Re: 6.5.4 - two questions

[Chris Whisonant <Chris.Whisonant@xxxxxxxxxxxxx>]

I have 3 dpars (mail, app, im) and I have right at 4400 MB memory. You do 
have the buffer pool set at the recommended (Total / # of DPARS * 3/8). 
But that could be causing some issues - what happens if you leave it at 
the default of 300?

I have only gotten the insufficient memory errors if one of my DPARs 
crashed and I haven't cleared up the shared memory or semaphores. In 
iSeries Navigator, you have to have all dpars offline to clear these. A 
couple of new commands can be viewed here:

These let you clean up shared memory and semaphores with just the one 
server down. While I've had my share of issues at 6.5.4, I haven't had 
these come up. I have my mail buffer pool at 396, app at 300, and IM at 
300. Even though they could all 3 be set at 550 (per my memory 
requirements), I have looked at the performance to come up with those 
numbers. A great reference I have is:

Go to section 4.2.2 for setting the buffer pool...
