Resolving References to External Systems

A captured workload may contain references to external systems, such as database links or external tables. Typically, you should reconfigure these external interactions to avoid impacting other production systems during replay. External references that need to be resolved before replay a workload include:

• Database links

  It is typically not desirable for the replay system to interact with other databases. Therefore, you should reconfigure all database links to point to an appropriate database that contains the data needed for replay.

• External tables

  All external files specified using directory objects referenced by external tables need to be available to the database during replay. The content of these files should be the same as during capture, and the filenames and directory objects used to define the external tables should also be valid.

• Directory objects

  You should reconfigure any references to directories on the production system by appropriately redefining the directory objects present in the replay system after restoring the database.

• URLs

  URLs need to be configured so that Web services accessed during the workload capture will point to the proper URLs during replay.

• E-mails

  To avoid resending E-mail notifications during replay, the mail server on the replay system should be configured to ignore requests for outgoing E-mails.
