Hi All,
My Job is getting abended on a perticular step every time due to lack of region available (U0008). I want to add REGION parameter to overcome this prob from that perticular step.
Problem is how can I measure the region parm needs to provide there.
Thanks & Regards,
Priyesh. |

I do not know how to measure the parm value. But by providing REGION=0M in the step will aquire all the available storage.Provided you are not overriding this in the JOB.

First, you may want to read the chapter "2.6.4 Resource Control of Address Space" in the MVS JCL User's Guide:
publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2B540/2.6.4?DT=20040712160458
It provides some details on using the REGION parameter for jobs or job steps.
In the real world, if I were experiencing problems with real storage, I would be in contact with my MVS Systems Programmers to determine what should be done. My gut feeling is that they would use a product such as Strobe to record the storage used by the executing program, and then use the analysis provided to recommend a reasonable value for your REGION size. If the program in question was provided by a vendor, I would be looking to them to make the recommendations for the REGION size.
Otherwise, if there is nothing preventing you from doing so, I would go with Som's recommendation and use REGION=0M. |

Think that is the only way, as putting REGION=0M is not feasable for me.
