iSeries Performance and Replication issue

HCL Domino Domino Forum

I know this is not the Domino 8 forum, but I didn’t get a response in that forum. Also it is possible that this issue is not totally associated with our upgrade. Here is my posting:

We upgraded our three production servers to Domino 8.0.1 like a week ago.

They are in a Cluster, so we decided to upgrade all at the same time to avoid possible design issues. The main server is on iSeries, and the other two are on Windows 2003 boxes.

In general, everything works well except for one database that is key for our manufacturing process. The behaivor of the replica in the iSeries is really poor when you compare it with the other two servers, making impossible to open the database. I have been trying to troubleshoot what is causing the issue, without any success.

I re-created the replica at least three times. At the very beginning, after the replica is created, it opens as fast as the other two replicas. After some time, the replication task start between the servers and basically it takes almost all the resources in the iSeries, making impossible to open the database again.

I tried to run fixup, and it said that an updall –r is required because one of the views is damage. Each time I ran the updall, looks like the Server process in the iSeries is grabbing more resources taking up to 80% of CPU.

My next step if take that database totally out of the iSeries. This database has some agents running every 5 minutes, like many others in our environment. I changed them to run in the other two servers, in order to provide the data to the users. One of the agents is Java the others LotusScript.

Does somebody has issues like this after upgrading to Domino 8 in the iSeries?

Any Ideas?

Any suggestion is appreciated.

Do you have enough memory allocated to the domino subsystem?

And if the db is damaged did you try doing a copy style compact on it?

Did you call support to see if they offer any debug advice?

Thanks for your response.

I don’t know how much memory we have assigned in the iseries for domino. That didn’t change with the upgrade. I will check that, but the other databases are working good.

I didn’t try copy style compact, because I delete that replica and re-created it at least three times. That is the same thing but faster consuming less resources.

Unless your iseries is grossly undersized then ram would almost always be the first thing to check. Also the activity level of the storage pool may need adjusted. Review the qpfradj sysval to see how memory and activity levels are being managed.

Also, IMO replicas of your db may also contain any damage that existed in the original. Copy style compact will allow you to ignore errors during the compact.
