Run RMF, I think monitor I, with the following option. This create
an RMF SMF enqueue record.
VIEW USER.PARMLIB(ERBRMF00) - 01.05
Command ===>
000014 ENQ(DETAIL)
Then run the RMF postprocessor as below.
//STEP010 EXEC PGM=ERBRMFPP
//MFPINPUT DD DISP=SHR,DSN=your.smf.data (Could be the currently
active MANx, or an SMF offload data set.
//MFPMSGDS DD SYSOUT=*
//SYSIN DD *
SYSOUT (X)

Hello everyone,
I wnat to know how to debug this situation after it occurred, in this case,
the next day. In this particular case Connect Direct was unable to pick
this library for a transmission task becuase it was in use by someone (user
ou job).
I did run RMFMONIII DSND "Data set delays" with 100sec sampling moving
forward and rewinding on time and I coundn't find anything.
But basically, what tool do you normally use for a situation like this ???
to find the enqueue after the problem take place ??
Many thx for all your sugestions, A.Cecilio.
