On AIX, the CPU performance abnormally spikes during a Content Manager EE login or during a query that uses the execute() or executeWithCallback() methods.
On some systems such as AIX POWER-series servers and virtualization environments, the default FIPS-certified version of IBM Global Security Kit (GSKit) might cause performance degradation. The non-FIPS certified version of GSKit contains a fix.
Enable the non-FIPS certified version of GSKit for the library server by setting the ICC_IGNORE_FIPS and ICC_TRNG environment variables:
ICC_IGNORE_FIPS=yes
ICC_TRNG=ALT
export ICC_IGNORE_FIPS ICC_TRNG
Then restart the DB2 instance
associated with your Content Manager EE library server database.SID_LIST_LISTENER_ECM =
...
(ENVS="...,ICC_IGNORE_FIPS=yes,ICC_TRNG=ALT")
Then
restart the named listener used to service the Content Manager EE library server.
