Yip, thats a golden oldie! Look at II07124 and OY25606 and perhaps others too. John McKown said in 2005: "We have DDCONS set to NO. Why? Because with DDCONS set to YES, our long running started tasks (such as NET and CA-7) took too long to terminate." ... and in 2006 this gem: "I think that DDCONS(YES) has something in it about efficient as a bubble sort of 100,000 records. Yuck!" Oh, someone told me last week about this one where DDCONS(NO) can resolve this problem: 'Slowdown in CICS TS every 15 minutes with resource manager waits and DB2 hanging' in Tech Note Reference #: 1206955 (year 2014) Steve Carlson wrote: > When trying to shut down the DB2 regions on our Development LPAR the DB2M1 > regions are taking over 1 hour to shut down.

As others kindly suggested, change your SMF settings. You may need to stop/start your DB2 subsystems to get the last SMF records out _AFTER_ you changed your SMF settings with T SMF=??. >Also these STC's have been up and running for over 60 days and are at Release >10. Release does not matter. Since what DB2 release did these problems happen? > Has anyone else seen this problem, and what did you do to resolve this > problem? Not only with DB2, in fact, any [usually longrunning] STCs with lots of datasets are having this problem.
