One reason to delete the members but not delete/reallocate the data set is there may be security issues about deleting and reallocating the data set. This happened to me long, long ago. You only need update access to delete members, but (typically) alter access to delete/reallocate the data set. Another, though very rare, issue may be an extents issue. If the data set is in multiple extents, you may not be able to reallocate the same size data set on the same volume. In a very bad case scenario, you have a data set with 15 tracks in 15 extents. You might not be able to get 15 tracks, much less 1 cylinder, on the volume in a delete/reallocate scenario.

Hi NicC..

I had read the docs and tried doing it.
But JCL when checked for syntax errors says "Dataset not found".

The doc says:
This parameter must be the first parameter following DELETE. entryname is the name of the entry to be deleted. A generic name can be coded to delete multiple entries with one entryname. (For example, GENERIC.*.BAKER is a generic name where * is any 1-to-8 character simple name.) Here is an example of how generic level DELETE works given the following data sets:
1) AAA.BBB.CCC.DDD
2) AAA.BBB.CCC.DDD
3) AAA.BBB.CCC.DDD.EEE
4) AAA.BBB.CCC

DELETE AAA.* results in the deletion of no data sets.
DELETE AAA.BBB.* results in the deletion of data set #4
DELETE AAA.BBB.*.DDD results in the selection of data sets #1 and #2
DELETE AAA.BBB.*.DDD.EEE results in the deletion of data set #3.

When a generic level name is specified, only one qualifier can replace the asterisk (*).



My JCL Looks like below:


//USERTEST JOB 3,'DELETE',CLASS=1,MSGCLASS=Y
//*
//STEP01 EXEC PGM=IDCAMS
//SYSOUT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
/ DELETE XM25.UBI04.*.AUG09
/*
//

When I compiled it Cond Code is 08 with the message:
"/ DELETE XM25.UBI04.*.AUG09
CAY6079E DATA SET "XM25.UBI04.*.AUG09" SPECIFIED AS OLD OR SHR, BUT
CANNOT BE FOUND
"
Thanks Always,
-Rupesh.

1) You do NOT conpile JCL - you submit it
2) IDCAMS control cards do not start with a /
The problem I have is that people can explain things quickly but I can only comprehend slowly.

But If I submit the same JCL with out giving the Wildcard * and with an known Dataset it is working without any issues.

What is the exact data set name you're trying to delete with the wild card? XM25.UBI04.A.AUG09 would be found and deleted, whereas XM25.UBI04.A.B.AUG09 would not since the wild card in IDCAMS only qualifies a single level (a point often missed).

Hi Robert,

I have so many datasets suffixed with Date fields and I am trying to remove all of the files which belongs to 2009.
Some Examples look like:
XM25.ABC.DEF.D010109
XM25.ABC.DEF.D020109
XM25.ABC.DEF.D030109 and so on.

Because I have more than 1000 different files with such date suffixed, is it possible to delete all of them in a single go?
Thanks Always,
-Rupesh.

Looking at your sample datasetname list your generic must be something like XM25.ABC.DEF.*09. This is invalid. An * must replace the ENTIRE name level. Check out the manual and see if it anywhere says *xx or xx* or xx*yy is allowed. ALL examples show .*. or .*
The problem I have is that people can explain things quickly but I can only comprehend slowly.
