When a user enters the CA Database Management fore DB2 for z/os products main menu settings from the parmlib (hlq.CDBAPARM ) are automatically brought in. Settings such as which members of *.CDBAPARM are being used of the many on that library to choose from. Also settings like dataset allocations for the various product and DB2 libraries.
When in the CA Database Management for DB2 for z/os products main menu there are two Option line OR Command line commands that will give the user information about the settings used. The STATUS command lists the actual CDBAPARM members being used and the FILES command lists the actual datasets that have been allocated. The STATUS command also tells the user the actual xmanager started task identifier that is being used. If there a problem then STATUS will tell you that also.
The report from the FILES command can be used to track back to the DSNAME00 and PTISYS00 members in hlq.CDBAPARM to see that the correct libraries are in use. In the FILES report the actual CDBAPARM library that was allocated can be found assigned to the PTIPARM DD.
The IBM ISRDDN diagnostic utility can also be used to list the datasets allocated.........TSO ISRDDN
The TSO ISRDDN command can be typed from the command line also!!
