Hi ,

We i try running a Load job, i got an abend 3301.

U3301: This pseudoabend is issued when the number of locks acquiredon behalf of the application program has exceeded the maximum specified bythe installation or application programmer. The maximum number of locks anapplication program can accumulate before committing is specified by thePSBGEN LOCKMAX= parameter or the LOCKMAX= override parameter in the DL/Ior DBB batch, or dependent region JCL.

Please advice on this( what could the cause for this abend)

As per my manual:

You can override the PSBGEN LOCKMAX= specification at execution time by specifying the LOCKMAX= parameter in the batch or dependent region JCL. An override parameter of LOCKMAX= 0 will turn off all locking limitations. The LOCKMAX value for the PSBGEN and override cases is in units of 1000. Each time the LOCKMAX value is increased by 10, the application is allowed to acquire 10,000 more locks.
Each application program is allowed to have its own limit on the maximum number of locks it can acquire, that is each application program can be individually constrained to a specific amount of virtual storage resources to be used for locking.
An errant application program that is not constrained can consume all locking storage and cause significant disruption to other application programs using the same locking services.

Please let us know if you need any more informatiopn about the same.
