I have one VSAM file defined to a region .. I want to know if this file is a Transactional VSAM file or not ..
I tried searching this Forum and Internet for help but most of the things went over head..

Could anyone tell me How to identify if a VSAM file is transactional or not ..

Hello,

Please define what you mean by "transactional VSAM".

That is not a term that has wide usage/understanding.

If a VSAM file is being used by CICS it can not be accessed by Batch.

To provide simultaneous access a concept of Transactional VSAM files was introduced where in file could be accessed by Batch and CICS both.

Hello,

You might try this command (if your system has the add-on).

Quote:
DISPLAY SMS,DSNAME(dsn)
For a given fully qualified data set name, this command displays the jobs
currently accessing the data set using DFSMStvs on the systems within the
sysplex. Figure 6-18 shows that the specified data set is not open for DFSMStvs
access.


From this redbookhttp://www.redbooks.ibm.com/redbooks/pdfs/sg246105.pdf

Do you have DFSMStvs installed ?

If so, speak to your storage people and they will be able to let you know which files are tvs defined.
