Checking Space and Resources
Before running the SWAP_BASE_LANGUAGE command, be sure that your database has sufficient space and resources to perform the swap process. Although the swap base language process commits after each table is successfully swapped, you need sufficient log space, or rollback space in the case of Oracle databases, to hold the contents of the largest table to be swapped.
On a newly installed PeopleSoft database, the PSPNLFIELD table is typically the largest table to be swapped, and this can be used as a benchmark for sizing your log space. Plan on at least 50 to 75 MB log or rollback segment space before running the swap process.
