Re: Subsystem and Apache Setup for Zend Server 6

One other point. Mike suggested that tuning the SQL server jobs is important, and he is right.

The database jobs should be in their own memory ( the QSQSRVR and QZDASOINIT jobs ) not associated with anything else. Of course you need enough memory to do it with as well.

Jim - I set up a new *SHRPOOL entry and changed the ZENDSVR6 subsystem to
use that shared pool:

Subsystem description: ZENDSVR6 Status: ACTIVE

Pool Storage Activity
ID Size (K) Level
1 *SHRPOOL6

Are you saying that I should change the QHTTPSVR subsystem to use the same
shared pool? And that I should change the Activity Level for the pool
definition in the SBSD to 200?

Thanks!
