If the file is getting created in the job, we can identify it as it will be created by giving CI (control interval, CA (control area) parameters which are specific to VSAM creation

Answer / ashis

browse the file in Start 3.4 option then see whether data
and index present. this the only way. how u can identify
only looking into it without doing anything else. Probably
God can identify by looking into it.

Answer / harsha

I know its not a generic answer, but many system used BUFND
(Buffer data) and BUFNI(Buffer Index) parameter while using
any VSAM file.

Answer / becky

JCL contains EXEC PGM=IDCAMS for doing any operation in VSAM. From that we can identify VSAM file is used in the JCL by seeing the JCL code itself.

Answer / selvam a

If the VSAM file is updated in a job, then definitely there
will be a backup step prior to the update step. The backup
can be a DASD backup (using IDCAMS utility - Repro) or a
Tape backup (using ADDRSSU utility). And if the job abends,
there will be a separate JCL to delete/define this VSAM file
and restore it from the backup taken.
So by checking these utilities presence we can make sure
that JCL has a VSAM file.
More over in our system, we differentiate a vsam file by
including a 'V' as the last character of the second
qualifier Ex: XXXX.YYYV.ZZZZ
I am not sure of the other systems.

Answer / sj@iy

Not sure of how to indentify via JCL, but it can be
identified in COBOL program through the SELECT clause

SECLECT file ASSIGN TO FileSystemID-Filename

Here, FileSystemID identifies a file as either of the
following
a) VSAM - (Coded as VSA or VSAM; E.g. SELECT FILE1 ASSIGN
TO VSA-MyFile)
b) STL - STL File System (E.g. SELECT FILE1 ASSIGN TO STL-
MyFile)
c)RSD- Record Sequential Delimited File System.

If the FileSystemID is ommited, then the runtime option
FILESYS treats the file as VSAM.

I have 20 steps in a job... step01, 02....step17...step20. For some reason I want to execute step17 only if the return code for all the previous steps are less than or equal to 4. otherwise if return code for any of the previous 16 steps is greater than 4, then step17 should be bypassed. How do I do that ?? how and in which step should i formulate COND parameter
