MDM-PI channel monitoring issue

Former Member

We are using standard customer, material, vendor repository and also a custom repository in our landscape and we have around 200 PI channels for MDM and 400 in total. PI channel monitoring not able to open the PI channels. We suspect it is do with MDM channels. We see the MDM-PI channels are actively connected always through MDM-PI Adapter.

MDM experts, Have you faced these issue?

Hi Subin,

First check whether the record processing by PI works properly. This can be checked in ready folder of the MDM ports. If the records are being processed from ready folders and are placed in Archive folders, then MDM PI adapter is working fine. If this is working try restarting the PI adapter engine once.

If the records are not processed in ready folder restart MDIS or MDSS accordingly and check.

Reply with your result.

I am trying to get into the root cause of the issues and if people have experienced the same. One observation is MDM PI adapter is having an active connection to MDS always. Is it possible to trigger MDM adapter connection only based on files appearing in MDM ready folders.

Hi Subin,

Very Interesting indeed.

Well if you switch to file adapter that would not maintain synchronous connection with MDM.

First of all I would say try to isolate the pain area.Search for area where the issue is arising.

You can look at MDS performance when the channels get locked.

The more write locks,more load on MDS the more the channels can create this problem.

Also,try to find the time taken by PI in processing messages at different times of load on PI and MDM.

Ravi,

Issue primarily has been on active MDM adapter connections even if there are no files to be processed. This in turn is causing PI channel monitoring to not function because there are around 200 MDM communication channels.

Hi Subin,

Please make provision for testing MDM server performance at various instances during the day.The more mass updates,strategy run,workflows,multiple users connecting the system etc. could cause this.Please test and update with result.

Hi Subin,

To address this, you have the option of ATP settings in PI. These interface Channel will be set to active mode during a set of time interval that would pick files from ready folder.

Thanks Mir. We are pursuing those option. Additionally, we received a MDM patch from SAP and that resolved the PI monitoring issue.

Hi Subin,

Yes you can schedule few channels and this can be helpful.However during business hours and peak load this would not help much.If MDS is busy the java connection would be waiting for the write lock to be free and hence performance issue would come up.

Kindly also look at removal of frequent write locks on data or make the time duration of lock very small by optimizating MDS performance.

Thanks,

Ravi
