Creating Oracle Database for Websphere Portal

Considerations before Creating database for Websphere Portal

View some important considerations before setting up Oracle databases to work with WebSphere Portal.

For information about creating databases, refer to the Oracle product documentation. For information on the recommended database architecture and the databases you will need to create, see the Planning for Oracle topic. Be sure that all databases to be used with WebSphere Portal are created as UNICODE character set databases.

If you are using remote Oracle databases, you must also copy the ojdbc14.jar file from the remote Oracle server to the WebSphere Portal machine. The typical location is the oracle_home/jdbc/lib directory. Record the copy location on your local machine for future reference.

When creating Oracle databases for use with WebSphere Portal, you should consider the following information:

  • The Oracle databases must be created manually before configuring WebSphere Portal.
  • All databases must be created using UNICODE Database and National character sets such as UTF8, AL32UTF8, or AL16UTF16.
  • It is recommended that all databases to be used with WebSphere Portal are configured in Dedicated Server Mode.
  • Determine if your Oracle server will be remote or local to the WebSphere Portal installation.
  • If using an earlier version of Oracle (9i), ensure that Oracle JVM is also installed.
  • After installing the database software for WebSphere Portal, you will need to set the buffer pools allocated to the Oracle database in order for WebSphere Portal to communicate with the Java Content Repository database. Use the following recommended values as a guide. Refer to Oracle product documentation for information on how to set the buffer pools. Recommended initial buffer pool sizes:
    db_block_size = 8192
    db_cache_size = 300M
    db_files = 1024
    log_buffer = 65536
    open_cursors = 1500
    pga_aggregate_target = 200M
    pre_page_sga = true
    processes = 300
    shared_pool_size = 200M
