If the target database is Oracle, you can optimize the target database by checking the storage clause, space allocation, and rollback or undo segments.

When you write to an Oracle database, check the storage clause for database objects. Make sure that tables are using large initial and next values. The database should also store table and index data in separate tablespaces, preferably on different disks.

When you write to Oracle databases, the database uses rollback or undo segments during loads. Ask the Oracle database administrator to ensure that the database stores rollback or undo segments in appropriate tablespaces, preferably on different disks. The rollback or undo segments should also have appropriate storage clauses.

To optimize the Oracle database, tune the Oracle redo log. The Oracle database uses the redo log to log loading operations. Make sure the redo log size and buffer size are optimal. You can view redo log properties in the init.ora file.

If the Integration Service runs on a single node and the Oracle instance is local to the Integration Service process node, you can optimize performance by using IPC protocol to connect to the Oracle database. You can set up Oracle database connection in listener.ora and tnsnames.ora.
