We have a performance issue that has surfaced lately on our TEST webmethods Integration Server. We use wm IS 6.5 SP2 and our DB2 database is JD Edwards EnterpriseOne 8.12 (Oracle) on an AS400. The IS is running on a Windows 2003 Server. We actually run four Integration Servers. Two Production and one Test (soon to be third Production) and then the one Test in question.
We restart the wM IS every night at 1:30 AM automatically. The database server and the three other wM servers reside all at the same location while the Test server in question resides in another data center 30 miles west of here but we do have a 1GB Fiberoptic connection between the two data centers.
If I send the first test order to one of my flows on that server in the morning around 8 AM then it takes around 15!!! minutes to process. I have an SMTP Email sent when the flow starts and then after the order has been created. I will get the first email right away and the other Email about 15 minutes after that one. If I then send a second order through after the first one it only takes 10-20 seconds to process through.
We have not used that server for testing for a while and we never used to have performance issues that severe before. I don’t have that kind of issue it seems with our other IS servers.
I guess after the restart wm IS first needs to reestablish the EnterpriseOne connection when the first order comes through and that takes so long? I will do a test tonight and have a job process shortly after the IS resets around 2 AM and then do my test job at 8 AM. Although I don’t know for how long the connection stays established if there is no activity.
Does anyone have any comments, suggestions, insight?
