Hi,
In my GDG number of generation kept is decided by the application team, therefore,my JCL should have an ability to let application team specifies the number of generation as a parameter. How can i achieve this.An early reply is highly appreciated
Cheers,
Pradeep Samson. |

Pradeep, If you are talking about changing you GDG's generation limit.
You can use IDCAMS with ALTER Command for the same.

... so, define a parameter in your PROC, and let them supply the value when their job calls it.
Or, am I missing something here?  |

Hi Priyesh,
I don't think,ALTER command in IDCAMS could be used to modify generation limit.It could be used for EMPTY/NO EMPTY & SCRATCH/NO SCRATCH but NOT to modify generation limit.ALTER has some limitations.

Hi ...
I think Sridevi is right ...
We can't change the limit of GDG by alter command |

Hi,
It is possible to alter the limit of a GDG using IDCAMS with ALTER command...check the example given below:
letz assume previously the limit was 5 and now if you want to change it to 10, then use
//STEP1 EXEC PGM=IDCAMS
//SYSIN DD *
ALTER MY.GDG.BASE LIMIT(10)
/*
(OR)
u can also change the limit by going to ISPF 3.4 option, give your GDG base name, after doing ENTER, i think you can type "ALTER LIMIT /" at the GDG dataset...then it prompts for "Enter the Limit"....and enter it as "10"....i dont remember this exactly...i have done like this long back...just try this one also...
Please let me know if you guys have any doubt....
Cheers,
Kumar |

Hi,
I agree with rtalapaneni. Once GDG has records,its limit can't be changed.Just like,the fact that when records are loaded the length of record and key length can't be changed by ALTER command.

Sridevi. |

Hi,
You can alter the limit parameter of the GDG base, when it contains the generations already loaded with the records. I remember, I had done like this before.
Thanks,
Kumar. |

Hi Guyz,
I am first time user to this site and wanted to reply on this query which you were talking about.
you can alter the gdg base which contain already some generations. alter command of the idcams won't work, we tried couple of times. we have a alternate way to do this:
#) Go to =6 on ISPF and try Alter "GDGName new limit(n)" -- Where 'n' is the new limit of your gdg.
I hope it solve your problem.
