ISE 3.3 High Undotablespace Usage

Just to let you know that our ISE 3.3 patch 2 deployment was reporting high undotablespace usage. After further investigation by Cisco, they found the issue and create a bug. This issue will be address in a future patch for this ISE version.

what symptoms/issues did you notice as a result? Is this service degrading/impacting? I was on patch 2 some months ago, and now on patch 3. Can't say I was even aware of this. But then again, I dare not look at the low-level ISE logs because they are always full of errors (Java mostly).

Hi @ajc ,

please take a look at:

ise/admin# application configure ise
 Selection configuration option
 ...

 ...

Bugs related to undotablespace that you should know:

CSCwh68651 ISE 3.1 P7 // Recreate undotablespace causes URT to fail

Hi Arne, sorry for not replying before. ISE 3.3 has multiple issues we have identified.

-DB being duplicated

-Purge process taking significant amount of time because of the previous with that purge running during regular operation hours.

-Patch 3 on ISE broke RFC 3164 that was fixed on ISE 2.6 (CSCvk09565 ISE 2.x onwards RFC 3164 is not being followed). There is no solution at this point.

The first 2 are supposed to be addressed on patch 5, we asked Cisco for a solution not a manual process via "application configure ise"
