Preparing to Access and Modify Information in Multiple Oracle Databases

This topic describes actions that are required to prepare your databases to access and modify information at other databases.

To prepare to access and modify information in multiple databases: 

1. Set the GLOBAL_NAMES initialization parameter to TRUE at each Oracle database in the distributed environment. See "Setting the GLOBAL_NAMES Initialization Parameter to TRUE" for instructions.

2. Configure network connectivity so that the databases can communicate with each other. See Configuring the Network Environment for information about configuring network connectivity between databases.
