Re: Dynamic access to IMS databases
Posted: Wed Apr 24, 2013 2:18 amIMS is not Java. Objects are not inherited. IMS requires a PSB to access Databases. The PSB statements define the databases to be accessed by the application program. The statement also defines the type of operations allowed by the application program. Each database requires a separate PCB statement. PSB generation allows for up to 255 database PCBs (less the number of alternate PCBs defined). That limitation alone suggests that even if you were to create a PSB to access everything, after 255 databases you will lose access.
