Configuration assistants that start after the installer interview process configure Oracle ASM and Oracle Clusterware.</p> <p>The installation of the combined products is called Oracle Grid Infrastructure. However, Oracle Clusterware and Oracle Automatic Storage Management remain separate products.</p> <a id="CEGFBIID" name="CEGFBIID"></a><a id="RIWIN918" name="RIWIN918"></a> <h3 class="prefsect2">Oracle Automatic Storage Management Cluster File System (Oracle ACFS)</h3> <p><a id="sthref13" name="sthref13"></a>Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is a new multi-platform, scalable file system and storage management design that extends Oracle Automatic Storage Management (Oracle ASM) technology to support all application data. Oracle ACFS provides dynamic file system resizing, and improved performance using the distribution, balancing and striping technology across all available disks, and provides storage reliability through Oracle ASM's mirroring and parity protection.</p> <div class="infoboxnote"> <p class="notep1">Note:</p> Oracle ACFS is only supported on Windows Server 2003 and Windows Server 2003 R2 64-bit.</div> <p><a id="sthref14" name="sthref14"></a>The Oracle ASM Dynamic Volume Manager (Oracle ADVM) extends Oracle ASM by providing a disk driver interface to Oracle ASM storage allocated as Oracle ASM volume files. You can use the Oracle ADVM to create virtual disks that contain file systems. File systems and other disk-based applications issue I/O requests to Oracle ADVM volume devices as they would to other storage devices on a vendor operating system. The file systems contained on Oracle ASM volumes can be used to support files beyond Oracle database files, such as executable files, report files, trace files, alert logs, and other application data files.</p> <a id="CEGECBJA" name="CEGECBJA"></a><a id="RIWIN919" name="RIWIN919"></a> <h3 class="prefsect2">Cluster Time Synchronization Service</h3> <p>Cluster node times should be synchronized, particularly if the cluster is to be used for Oracle Real Application Clusters. With this release, Oracle Clusterware provides Cluster Time Synchronization Service (CTSS), which ensures that there is a synchronization service in the cluster. If Network Time Protocol (NTP) is not found during cluster configuration, then CTSS is configured to ensure time synchronization.</p> <a id="CEGJFCGE" name="CEGJFCGE"></a><a id="RIWIN921" name="RIWIN921"></a> <h3 class="prefsect2">Database Agent and Listeners</h3> <p>With this release, DBCA no longer sets the value for LOCAL_LISTENER. When Oracle Clusterware starts the database resource, it updates the instance parameters. The LOCAL_LISTENER is set to the virtual IP endpoint of the local node listener address. You should not modify the setting for LOCAL_LISTENER. New installation instances only register with Single Client Access (SCAN) listeners as remote listeners. SCANs are virtual IP addresses assigned to the cluster, rather than to individual nodes, so cluster members can be added or removed without requiring updates of clients served by the cluster. Upgraded databases will continue to register with all node listeners, and additionally the SCAN listeners.</p> <a id="CEGFAGCI" name="CEGFAGCI"></a><a id="RIWIN922" name="RIWIN922"></a> <h3 class="prefsect2">Daylight Savings Time Upgrade of Timestamp with Timezone Data Type</h3> <p>When time zone version files are updated, TIMESTAMP WITH TIMEZONE (TSTZ) data could become stale. In previous releases, database administrators ran the SQL script <code>utltzuv2.sql</code> to detect TSTZ data affected by the time zone version changes and then had to carry out extensive manual procedures to update the TSTZ data.</p> <p>With this release, TSTZ data is updated transparently with very minimal manual procedures using newly provided DBMS_DST PL/SQL packages. In addition, there is no longer a need for clients to patch their time zone data files.</p> <div class="infoboxnotealso"> <p class="notep1">See Also:</p> <a class="olink UPGRD" href="http://www.oracle.com/pls/db112/lookup?id=UPGRD"><span class="italic">Oracle Database Upgrade Guide</span></a> for information about preparing to upgrade Timestamp with Time Zone data, <a class="olink NLSPG" href="http://www.oracle.com/pls/db112/lookup?id=NLSPG"><span class="italic">Oracle Database Globalization Support Guide</span></a> for information about how to upgrade the Time Zone file and Timestamp with Time Zone data, and <a class="olink LNOCI" href="http://www.oracle.com/pls/db112/lookup?id=LNOCI"><span class="italic">Oracle Call Interface Programmer's Guide</span></a> for information about performance effects of clients and servers operating with different versions of Time Zone files</div> <a id="CEGCJDCJ" name="CEGCJDCJ"></a><a id="RIWIN923" name="RIWIN923"></a> <h3 class="prefsect2">Enterprise Manager Database Control Provisioning</h3> <p>Enterprise Manager Database Control 11<span class="italic">g</span> provides the capability to provision automatically Oracle Grid Infrastructure and Oracle RAC installations on new nodes, and then extend the existing Oracle Grid Infrastructure and Oracle RAC database to these provisioned nodes. This provisioning procedure requires a successful Oracle RAC installation before you can use this feature.</p> <div class="infoboxnotealso"> <p class="notep1">See Also:</p> <a class="olink RACAD" href="http://www.oracle.com/pls/db112/lookup?id=RACAD"><span class="italic">Oracle Real Application Clusters Administration and Deployment Guide</span></a> for information about this feature</div> <a id="CEGEFBGD" name="CEGEFBGD"></a><a id="RIWIN924" name="RIWIN924"></a> <h3 class="prefsect2">Enterprise Manager Clusterware Resource Management</h3> <p>With this release, you can use Enterprise Manager Cluster Home page to perform full administrative and monitoring support for both standalone database and Oracle RAC environments, using High Availability Application and Oracle Clusterware Resource Management. Such administrative tasks include creating and modifying server pools.</p> <a id="CEGFHICE" name="CEGFHICE"></a><a id="RIWIN925" name="RIWIN925"></a> <h3 class="prefsect2">Enterprise Manager Patch Application</h3> <p>With this release, you can apply patches to the Oracle RAC database using Enterprise Manager. A new Enterprise Manager feature, the Provisioning Advisor Console, enables you to customize, monitor, and deploy patch applications to nodes on the cluster.</p> <a id="BGGJCEEJ" name="BGGJCEEJ"></a><a id="RIWIN926" name="RIWIN926"></a> <h3 class="prefsect2">Grid Plug and Play</h3> <p><a id="sthref15" name="sthref15"></a>In the past, adding or removing servers in a cluster required extensive manual preparation. With this release, you can continue to configure server nodes manually, or use Grid Plug and Play to configure them dynamically as nodes are added or removed from the cluster.</p> <p>Grid Plug and Play reduces the costs of installing, configuring, and managing server nodes by starting a grid naming service within the cluster to allow each node to perform the following tasks dynamically:</p> <ul> <li> <p>Negotiating appropriate network identities for itself</p> </li> <li> <p>Acquiring additional information it needs to operate from a configuration profile</p> </li> <li> <p>Configuring or reconfiguring itself using profile data, making host names and addresses resolvable on the network</p> </li> </ul> <p>Because servers perform these tasks dynamically, adding and removing nodes simply requires an administrator to connect the server to the cluster, and to allow the cluster to configure the node. Using Grid Plug and Play, and using best practices recommendations, adding a node to the database cluster is part of the normal server restart, and removing a node from the cluster occurs automatically when a server is turned off.</p> <a id="CEGEDIHA" name="CEGEDIHA"></a><a id="RIWIN927" name="RIWIN927"></a> <h3 class="prefsect2">Improved Deployment, Deconfiguration and Deinstallation</h3> <p>Oracle configuration assistants provide additional guidance to ensure recommended deployment, and to prevent configuration issues.</p> <p>Oracle configuration assistants provide the capability of deconfiguring and deinstalling Oracle Real Application Clusters, without requiring additional manual steps.</p> <a id="BGGCEBAE" name="BGGCEBAE"></a><a id="RIWIN928" name="RIWIN928"></a> <h3 class="prefsect2">SCAN for Simplified Client Access</h3> <p><a id="sthref16" name="sthref16"></a><a id="sthref17" name="sthref17"></a>With this release, the single client access name (SCAN) is the address to provide for all clients connecting to the cluster. The SCAN is a domain name registered to at least one and up to three IP addresses, either in the domain name service (DNS) or the Grid Naming Service (GNS). The SCAN eliminates the need to change clients when nodes are added to or removed from the cluster. Clients using SCAN can also access the cluster using Easy Connect Naming.</p> <a id="CEGIJFIB" name="CEGIJFIB"></a><a id="RIWIN929" name="RIWIN929"></a> <h3 class="prefsect2">SRVCTL Command Enhancements for Patching</h3> <p>With this release, you can use <code>srvctl</code> to shut down all Oracle software running within an Oracle home, in preparation for patching. Oracle Grid Infrastructure patching is automated across all nodes, and patches can be applied in a multi-node, multi-patch fashion.</p> <a id="CEGHGBDI" name="CEGHGBDI"></a><a id="RIWIN930" name="RIWIN930"></a> <h3 class="prefsect2">Desktop Class and Server Class Installation Options</h3> <p>In this release, there are two installation types: Desktop Class and Server Class.</p> <p>The Desktop Class installation type is a simplified installation with a minimal number of manual configuration choices. The Desktop Class installation performs a full Oracle Database installation with a basic configuration.</p> <p>The Server Class installation type allows for more advanced configuration options. Select this option when installing Oracle RAC, if you use Enterprise Manager Grid Control, or if you want to configure database storage on Oracle ASM.</p> <a id="CEGEHIGI" name="CEGEHIGI"></a><a id="RIWIN931" name="RIWIN931"></a> <h3 class="prefsect2">Zero Downtime Patching for Oracle RAC</h3> <p>Opatch now can apply patches in multi-node, multi-patch fashion, and will not start up instances that have a non-rolling patch applied to it if other instances of the database do not have that patch. Opatch also detects if the database schema is an earlier patch level than the new patch, and it runs SQL commands to bring the schema up to the new patch level.</p> <div class="infoboxnotealso"> <p class="notep1">See Also:</p> <a class="olink OUICG" href="../../em.112/e12255/toc.htm"><span class="italic">Oracle Universal Installer and OPatch User's Guide for Windows and UNIX</span></a></div> <a id="CHDIFCBB" name="CHDIFCBB"></a> <h3 class="prefsect2">Deinstallation Tool</h3> <p>Oracle Universal Installer no longer removes Oracle software. Use the new Deinstallation Tool (<code>deinstall.bat</code>) available on the installation media before installation as well as in the Oracle home directory after installation. This tool can also be downloaded from Oracle TechNet.</p> <div class="infoboxnotealso"> <p class="notep1">See Also:</p> <a href="rem_orcl.htm#CIHBHIJH">Chapter 8, "Removing Oracle Real Application Clusters Software"</a> for more information</div> <a id="CHDGHHCH" name="CHDGHHCH"></a> <h3 class="prefsect2">Deprecated Options with Oracle RAC 11<span class="italic">g</span> Release 2 (11.2)</h3> <p>Note the following changes with this release:</p> <ul> <li> <p><a id="sthref18" name="sthref18"></a><a id="sthref19" name="sthref19"></a><a id="sthref20" name="sthref20"></a><a id="sthref21" name="sthref21"></a>Installing files on raw devices is no longer an option available during installation.

The main objective of this feature is to reduce the time required to resolve bugs. Automatic Diagnostic Repository is the layer of the Diagnostic Framework implemented in Oracle Database 11<span class="italic">g</span> that stores diagnostic data and also provides service APIs to access data. The default directory that stores the diagnostic data is <code>ORACLE_BASE\diag</code>.</p> <p>The Automatic Diagnostic Repository implements the following:</p> <ul> <li> <p>Diagnostic data for all Oracle products is written into an on-disk repository.</p> </li> <li> <p>Interfaces that provide easy navigation of the repository, and the capability to read and write data</p> </li> </ul> <p>For Oracle RAC installations, if you use a shared Oracle Database home, then the Automatic Data Repository must be located on a shared storage location available to all the nodes.</p> <p>Oracle Clusterware continues to place diagnostic data in the directory <code><span class="codeinlineitalic">CRS_home</span></code><code>\log</code>, where <code><span class="codeinlineitalic">CRS_home</span></code> is the Oracle Clusterware home.</p> <a id="RIWIN944" name="RIWIN944"></a><a id="sthref34" name="sthref34"></a> <h4 class="prefsect3">Oracle Automatic Storage Management Fast Mirror Resync</h4> <p>Oracle ASM fast mirror resync quickly resynchronizes Oracle ASM disks within a disk group after transient disk path failures as long as the disk drive media is not corrupted. Any failures that render a failure group temporarily unavailable are considered transient failures. Disk path malfunctions, such as cable disconnections, host bus adapter or controller failures, or disk power supply interruptions, can cause transient failures. The duration of a fast mirror resync depends on the duration of the outage. The duration of a resynchronization is typically much shorter than the amount of time required to completely rebuild an entire Oracle ASM disk group.</p> <div class="infoboxnotealso"> <p class="notep1">See Also:</p> <span class="italic">Oracle Database Storage Administrator's Guide</span></div> <a id="RIWIN945" name="RIWIN945"></a><a id="sthref35" name="sthref35"></a> <h4 class="prefsect3">Oracle ASM and Oracle RAC Deinstallation and Other Configuration Assistant Enhancements</h4> <p>Database Configuration Assistant (DBCA), Database Upgrade Assistant (DBUA), and Oracle Net Configuration Assistant (NETCA) have been improved. These improvements include the following:</p> <a id="RIWIN946" name="RIWIN946"></a><a id="sthref36" name="sthref36"></a> <h5 class="prefsect4">DBCA</h5> <ul> <li> <p>Provides a command line feature, <code>deleteASM</code>, that removes Oracle ASM instances.</p> </li> <li> <p>Provides the option to switch from a database configured for Oracle Enterprise Manager Database Control to Oracle Enterprise Manager Grid Control.</p> </li> </ul> <a id="RIWIN947" name="RIWIN947"></a><a id="sthref37" name="sthref37"></a> <h5 class="prefsect4">DBUA</h5> <ul> <li> <p>Includes an improved pre-upgrade script to provide space estimation, initialization parameters, statistics gathering, and new warnings. DBUA also provides upgrades from Oracle Database releases 9.0, 9.2, 10.1, and 10.2.</p> </li> <li> <p>Supports in-place patch set upgrades</p> </li> <li> <p>Starts any services running prior to upgrades</p> </li> </ul> <a id="RIWIN948" name="RIWIN948"></a><a id="sthref38" name="sthref38"></a> <h4 class="prefsect3">New SYSASM Privilege for Oracle ASM Administration</h4> <p>This feature introduces a new <code>SYSASM</code> privilege that is specifically intended for performing Oracle ASM administration tasks. Using the <code>SYSASM</code> privilege instead of the <code>SYSDBA</code> privilege provides a clearer division of responsibility between Oracle ASM administration and database administration.</p> <a id="RIWIN949" name="RIWIN949"></a><a id="sthref39" name="sthref39"></a> <h4 class="prefsect3">Oracle ASM Preferred Read Disk Groups</h4> <p>In previous releases, Oracle ASM used the disk with the primary copy of a mirrored extent as the preferred disk for data reads. With this release, using the new initialization file parameter <code>asm_preferred_read_failure_groups</code>, you can specify disks located near a specific cluster node as the preferred disks from which that node obtains mirrored data. This option is presented in Database Configuration Assistant (DBCA), or you can configure it after installation. This change facilitates faster processing of data with widely distributed shared storage systems or with extended clusters (clusters whose nodes are geographically dispersed), and improves disaster recovery preparedness.</p> <a id="RIWIN950" name="RIWIN950"></a><a id="sthref40" name="sthref40"></a> <h4 class="prefsect3">Oracle Automatic Storage Management Rolling Migration</h4> <p>Rolling migration for Oracle ASM enables you to upgrade or patch Oracle ASM instances on clustered Oracle ASM nodes without affecting database availability. Rolling migration provides greater availability and more graceful migration of Oracle ASM software from one release to the next. This feature applies to Oracle ASM configurations that run on Oracle Database 11<span class="italic">g</span> release 1 (11.1) and later. In other words, you must already have Oracle Database 11<span class="italic">g</span> release 1 (11.1) installed before you can perform rolling migrations.</p> <div class="infoboxnote"> <p class="notep1">Note:</p> You cannot change the owner of the Oracle ASM or Oracle Database home during an upgrade. You must use the same Oracle software owner that owns the existing Oracle ASM or Oracle Database home.</div> <div class="infoboxnotealso"> <p class="notep1">See Also:</p> <span class="italic">Oracle Database Storage Administrator's Guide</span></div> <a id="RIWIN951" name="RIWIN951"></a><a id="sthref41" name="sthref41"></a> <h4 class="prefsect3">Conversion of Single-Instance Oracle ASM to clustered Oracle ASM</h4> <p>Using either Oracle Enterprise Manager Grid Control or <code>rconfig</code>, you can convert an existing Oracle ASM instance from a single-instance storage manager to a clustered storage manager. You can convert Oracle ASM release 11.1 instances directly, and convert releases previous to 11.1 by upgrading the instance to 11.1, and then performing the conversion.</p> <a id="RIWIN952" name="RIWIN952"></a><a id="sthref42" name="sthref42"></a> <h4 class="prefsect3">Data Mining Schema Creation Option</h4> <p>In Oracle Database 11<span class="italic">g</span>, the data mining schema is created when you run the SQL script <code>catproc.sql</code> as the SYS user. Therefore, the data mining option is removed from the Database Features screen of Database Configuration Assistant.</p> <a id="RIWIN954" name="RIWIN954"></a><a id="sthref43" name="sthref43"></a> <h4 class="prefsect3">Oracle Disk Manager Network File System Management</h4> <p>Oracle Disk Manager (ODM) can manage network file systems (NFS) on its own, without using the operating system kernel NFS driver. This is referred to as Direct NFS. Direct NFS implements NFS version 3 protocol within the Oracle RDBMS kernel. This change enables monitoring of NFS status using the ODM interface. The Oracle RDBMS kernel driver tunes itself to obtain optimal use of available resources.</p> <p>This feature provides the following:</p> <ul> <li> <p>Ease of tuning, and diagnosability, by giving the Direct NFS Client control over the input-output paths to Network File Server, and avoiding the need to tune network performance at the operating system level.</p> </li> <li> <p>A highly stable, highly optimized NFS client for database operations.</p> </li> <li> <p>Use of the Oracle buffer cache, rather than the file system cache, for simpler tuning.</p> </li> <li> <p>A common, consistent NFS interface, capable for use across Linux, UNIX and Windows platforms.</p> </li> <li> <p>Does not require additional configuration of NFS mounts. With operating system NFS drivers, even though NFS is a shared file system, NFS drives have to be mounted with the option <code>noac</code> (No Attribute Caching) to prevent the operating system NFS driver from optimizing the filesystem cache by keeping file attributes locally. ODM automatically recognizes Oracle RAC instances, and performs appropriate operations for data files without requiring additional reconfiguration from users, system administrators, or DBAs.</p> </li> </ul> <a id="RIWIN955" name="RIWIN955"></a><a id="sthref44" name="sthref44"></a> <h4 class="prefsect3">Optimal Flexible Architecture (OFA) Simplified</h4> <p>With the development of stripe and mirror everything architecture (SAME), and improved storage and throughput capacity for storage devices, the original OFA mission to enhance performance has shifted to its role of providing well-organized Oracle installations with separated software, configuration files and data. This separation enhances security, and simplifies upgrade, cloning, and other administrative tasks.</p> <p>Oracle Database 11<span class="italic">g</span> release 1 (11.1) incorporates several changes to OFA to address this changed purpose.</p> <p>As part of this change:</p> <ul> <li> <p>During Oracle RAC installation, you are prompted to accept the default, or select a location for the Oracle base directory, instead of the Oracle home directory. This change facilitates installation of more than one Oracle home directory in a common location, and separates software units for simplified administration. For this release, you are not required to use Oracle base, but this may become a requirement in a future release.</p> </li> <li> <p>With this release, as part of the implementation of Automatic Diagnostic Repository (ADR), the following <code>admin</code> directories are changed:</p> <ul> <li> <p><code>bdump</code> (location set by the <code>background_dump_dest</code> initialization parameter; storage of Oracle background process trace files)</p> </li> <li> <p><code>cdump</code> (location set by the <code>core_dump_dest</code> initialization parameter; storage of Oracle core dump files)</p> </li> <li> <p><code>udump</code> (location set by the <code>user_dump_dest</code> initialization parameter; storage of Oracle user SQL trace files)</p> </li> </ul> <p>By default, the location of these trace and core files is in the <code>\diag</code> directory, which is in the path <code>ORACLE_BASE\diag</code>.</p> </li> <li> <p>The initialization parameters <code>BACKGROUND_DUMP_DEST</code> and <code>USER_DUMP_DEST</code> are deprecated. They continue to be set, but you should not set these parameters manually.</p> </li> <li> <p>A new initialization parameter is introduced. <code>DIAGNOSTIC_DEST</code> contains the location of "ADR base," which is the base directory under which one or more Automatic Database Repository homes are kept. Oracle documentation commonly refers to these homes as ADR homes. Each database instance has an ADR home, which is the root directory for a number of other directories that contain trace files, the alert log, health monitor reports, and dumps for critical errors. You can also view alert and trace files with the SQL statement <code>select name, value from v$diag_info</code>.</p> </li> <li> <p>The default Flash Recovery area is moved from <code>ORACLE_HOME\..\flash_recovery_area</code> to <code>ORACLE_BASE\flash_recovery_area</code>.</p> </li> <li> <p>The default data file location is moved from <code>ORACLE_HOME\..\oradata</code> to <code>ORACLE_BASE\oradata</code>.</p> </li> <li> <p>A new utility, The ADR Command Interpreter (ADRCI), is introduced. The ADRCI facilitates reviewing alert log and trace files.</p> </li> </ul> <p>For Oracle RAC installations, Oracle requires that the flash recovery area and the data file location are on a location shared among all the nodes. The Oracle Universal Installer confirms that this is the case during installation. This change does not affect the location of trace files for Oracle Clusterware.</p> <div class="infoboxnotealso"> <p class="notep1">See Also:</p> <span class="italic">Oracle Database Administrator's Guide</span> for detailed information about these changes, and <span class="italic">Oracle Database Utilities</span> for information about viewing alert log and list trace files with ADRCI</div> <a id="CEGIBGBG" name="CEGIBGBG"></a><a id="RIWIN956" name="RIWIN956"></a> <h4 class="prefsect3"><a id="sthref45" name="sthref45"></a>Oracle Configuration Manager for Improved Support</h4> <p>During a custom installation, you are asked if you want to install Oracle Configuration Manager (OCM). OCM is an optional tool that enables you to associate your configuration information with your My Oracle Support account. This can facilitate handling of service requests by ensuring that server system information is readily available.</p> <p>Configuring the OCM tool requires that you have the following information from your service agreement:</p> <ul> <li> <p>Customer Identification Number (CSI)</p> </li> <li> <p>My Oracle Support user account name</p> </li> <li> <p>Country Code</p> </li> </ul> <p>In addition, you are prompted for server proxy information, if the host system does not have a direct connection to the Internet.</p> <a id="RIWIN957" name="RIWIN957"></a><a id="sthref46" name="sthref46"></a> <h4 class="prefsect3">Support for Large Data Files</h4> <p>Large data file support is an automated feature that enables Oracle to support larger files on Oracle ASM more efficiently and to increase the maximum file size.</p> <div class="infoboxnotealso"> <p class="notep1">See Also:</p> <span class="italic">Oracle Database Storage Administrator's Guide</span></div> <a id="RIWIN958" name="RIWIN958"></a><a id="sthref47" name="sthref47"></a> <h4 class="prefsect3">Switching a Database from Database Control to Grid Control Configuration</h4> <p>In previous releases, Database Configuration Assistant contains the functionality to configure databases while creating them either with Database Control or with Grid Control, or to reconfigure databases after creation. However, if you want to change the configuration from Database to Grid control, then this requires significant work. With Oracle Database 11<span class="italic">g</span>, Database Configuration Assistant enables you to switch configuration of a database from Database Control to Grid Control by running the Oracle Enterprise Manager Configuration Plug-in.</p> <a id="RIWIN959" name="RIWIN959"></a><a id="sthref48" name="sthref48"></a> <h4 class="prefsect3">New Features in Oracle Database 11<span class="italic">g</span> Release 11.1</h4> <p>Oracle Database 11<span class="italic">g</span> release 11.1 includes the following:</p> <ul> <li> <p>ODP .NET Configuration</p> <p>Developers can now configure ODP .NET using configuration files, including application config, <code>web.config</code>, or <code>machine.config</code>.</p> <p>Settings in the <code>machine.config</code> override the registry settings and the settings in the application config or the <code>web.config</code> override the values in the <code>machine.config</code>.</p> </li> <li> <p>Performance Enhancements</p> <p>The following performance enhancements have been made:</p> <ul> <li> <ul> <li> <p>Improved Parameter Context Caching</p> <p>This release enhances the existing caching infrastructure to cache ODP .NET parameter contexts.
