I wish there was. I hope someone will reply with a good method. First, add up all the blocks for the tables and their indexes you have assigned to the KEEP pool. Some of them may have grown over the past months and you may not have enough space allocated for all of them. Check the BHR for the KEEP pool to see what hit ratio you are getting. It should be 100%. Past that, you can consider the tables you have assigned to the KEEP pool and other small tables that you haven't assigned to the KEEP pool to decide if you have the best candidates assigned. You are looking for small tables that are accessed a lot. Based on your analysis and the available memory, you may decide to increase or reduce the size of the KEEP pool. Again, I really hope you (and I) receive a better reply.

Hi all,
Is there any way / script to find whether the tables kept in KEEP Buffer pool performing fine i.e. do they really need to be in the KEEP buffer pool or should they be removed. Tables that I want to check are in the buffer pool for over 6 months and I want to know if I should let them be there or be removed from there.

Regards,
