Improve your Domino Server Performance on the System i

On Windows it is pretty clear that Domino Servers only perform well, when the admin regulary defragment the file system where the Domino data is stored. Unfortunatly many System i admins do not know that fragmentation of Domino databases is a problem on their system too. So they do not get the best performance possible and with every year of using the server the problem of framgentation gets bigger and bigger.The defragmentation of the disks in a System i Server can be done with the command . So login into your System i with a 5250 Terminal client and execute the command: STRDSKRGZ ASP(*ALL) TIMLMT(*NOMAX)The ASP Parameter means that you want to reorganize all Auxilliary Storage Pools (Normally you have only one of this, but if you have more of them, then *all handles them all)The Timlmt(*NOMAX) means that the System i should defragment the ASP till all data is complete defragmented. As an alternative you can specify a exact time how long you want do defrag the disk. Disk reorganization stop automatically when the timelimit is reached.As the disk reorganization runs in the background and on a very small runtime priority, you do not have to stop your domino server or other system i tasks running.When you want to stop the reorganization before it is finished or the time limit has elapsed you can use the command.ENDDSKRGZ ASP(*ALL) When a disk reorganization is started a CPI1470 Message is logged in the System i log and when the reorganization finishes a CPI1472 message is logged. You can find the reason why the execution hast stopped in the message details of CPI1472.You can scan the System i log for this messages with the DSPLOG command.DSPLOG MSGID(CPI1470 CPI1472) So give your Domino server on the the system i a performance boost and execute the disk reorganization regulary. My suggestion is to add the command to the job scheduler of the System i. - Full Post
