Hi,

I am experiencing an odd problem.

We have upgraded our Metastorm from version 7.5 to Metastorm 7.6. We published all maps, and we took care of their dependencies.

We tested the flows  in our development server, and everything worked according to the plan. The flows were fine and there is no issue with the performance. The development server is having both, the DB and the application installed.

However, when we moved the changes to production,  and when we tried to test the flows, we have encountered a slowness issue. The server setup in production is as follow: 1 Application server, 2 DB servers and a Cluster.

The slowness is happening when the request is moving from one stage to another (Similarly from one stage to another action and so on). For example, consider the following map:

Moving from System Stage A to Action 2, takes around 3 minutes. Moving from Information Stage to System Stage B, takes more than 3 minutes, and so on for the rest of the stages. The timing was taken and verified from the eEvent Table.

The code in the stages and in the actions is not complicated. And in our previous development server where we have Metastorm version 7.6, it does not take seconds to pass through and complete the stages.

We also checked Service Manager for any trace. But, with not avail.

Seeking your advice and directions please.

Your response would be highly appreciated.

Thank you.

With Regards,
Mohd Rafeea

Are all the server times in sync? We've seen metastorm act real strange when the engine was off the DB server even by few seconds.

Hello praxkan,

My apologies I just saw your reply. Thank you for sharing this with me.

I checked our servers and the servers times were not in sync. I tried your suggestion and unified the server times. The slowness still exists.

Is there any suggestion or a try you could advise me to do?

With Regards,
Rafeea

Hmm, not sure what else it could be. Did you recycle the engine after you changed dates?

Hello praxkan,

When you advised me to recycle the engine, are you referring to restart the Metastorm process from services? If so, then yes we did that. The slowness still exists.

We have also rebuilt all indexes for all tables (eEvent, eFolder, etc ...). This did not help.

The odd thing is that, in our test instance, we are not facing this slowness. It is only when we moved to our production server.

Just to add something.

In our development instance, it is one server which has the DB and the application installed. In our production server, the setup is as follow: (One Server for application, two servers for the DB and one cluster).

We tried to disable the firewalls in all production server. The problem still exists.
