How to check db2 version

Question

How to check db2 version on Z/OS using only SQL commands?

Thanks, Melita

Answer 1

There is a typo in your SQL. Fixed version is below:

SELECT GETVARIABLE('SYSIBM.VERSION') FROM SYSIBM.SYSDUMMY1;

I ran this on the IBM Mainframe under Z/OS in QMF and got the following results. We are currently running DB2 Version 8 and upgrading to Ver 10.

DSN08015  -- Format seems to be DSNVVMMM
-- PPP IS PRODUCT STRING 'DSN'
-- VV IS VERSION NUMBER E.G. 08
-- MMM IS MAINTENANCE LEVEL E.G. 015

Answer 2

You can query for the built-in session variables with SQL. To identify the version of DB2 on z/OS, you need the SYSIBM.VERSION variable. This will return the PRDID - the product identifier. You can look up the human-readable version in the Knowledge Center.

SELECT GETVARIABLE('SYSIBM.VERSION')
FROM SYSIBM.SYSDUMMY1;

-- for example, the above returns DSN10015
-- DSN10015 identifies DB2 10 in new-function mode (see second link above)

Answer 3

db2ls command will display the db2level along with the install path and install date.

To determine the specific product installed:

db2ls -p -q -b <installpath>

on db2ls command.

The following will appear:

Install Path       Level   Fix Pack   Special Install Number   Install Date    Installer UID
