Re: runnable process search count
Others have already commented on the fact that ASE's threaded kernel uses a different model than the process kernel. Thread pools have an idle timeout defined in microseconds. Rarely would you need...

Hi, We have recently migrated from ASE 15.0.3 to ASE 15.7 SP132 on Solaris 10 platform. A 343 line stored procedure was modified to print a timestamp value at the start of the execution along with one...

Too many unknowns at this point ... what your proc is doing, how the ASE is configured, other activity on the ASE, etc, etc, etc. Can you post a (small) proc that reproduces the issue? Alternatively,...

Is this delay seen if the procedure is executed a second time fairly soon?As it sounds like it was a constant problem when "with recompile" was on, I'm wondering if a good deal of the time might be in...

Mark/Bret, Bret: Your assumption is correct. The second and subsequent runs execute extremely quickly because the plan is in cache. Also, the stored procedure has a number of complex joins along with...

OK, really slow first run (with tons of cpu usage), really fast second run, definitely sounds like a compilation issue. NOTE: Some of the following may be buried in those stacktraces ... I'll leave...

re: estimated execution time The short answer is the optimizer looks at table/index/column stats, optimization goal/options, and query complexity. While you could try tweaking your system to get a more...
