Dear Stefan,
Thank you for the response.
I meant to say in my previous post that I'm changing the undo_management parameter from MANUAL to AUTOMATIC. I found quite a few of our 11.2.0.3 databases that are still using MANUAL undo management. I will be following the guide in Note 600141 to do this.
I was referring to the SAP recommended default for the UNDO tablespace, whether to create it with retention guarantee or not?
I found oracle notes about "retention guarantee" that mention: "This option is disabled by default. Enabling retention guarantee can cause multiple DML operations to fail. Use with caution". With this in mind it seems I should rather not add it by default?
I also notice a few databases contain all the PSAPROLL, PSAPROLLBIG and PSAPUNDO tablespaces. In these databases only the segmens for PSAPROLL are ONLINE, and for the rest are offline. Should I follow roughly the same SAP note to move to PSAPUNDO tablespace and remove PSAPROLL and PSAPROLLBIG tablespaces? I noticed in the guide that PSAPROLL are the old format of PSAPUNDO.
Response will be appreciated.
Thanks and Regards,
Willem
