We are running Z/OS DB2 version 8 - but just in 'compatibility mode'.
That is the mode where they don't yet convert the DB2 catalogue.

Soon we will be entering 'new function' mode and by then the DB2 catalogue will be converted to the version 8 format.

To prepare for this, I want to get a sneak preview of how the SYSIBM db2 catalogue tables have changed. We have some dynamic processes that read these tables, and that will probably require some adjustments.

Where can I get documentation that will provide me with the structures of the SYSIBM db2 catalogue tables for Z/OS version 8 ?

thank-you for anyone who can assist.

You can find the catalog tables in the manual:

I think you are right that V8 CM hasn't convert the catalog table yet.

One way to verify it, you can try look at syscolumns

SELECT NAME, COLTYPE, LENGTH FROM SYSIBM.SYSCOLUMNS WHERE TBNAME = 'SYSTABLES' AND TBCREATOR = 'SYSIBM'.

then compare the column type and length with v7 sql ref, to see whether they are the same.

need to take my words back. V8 CM already change some catalog definition.
