Hi ,

I would like to know :
1.how to find all the schema in my DB2 database on Main frame
machine .
2. How to see all the tables for a given schema .
3. What are the default schema in Db2 on Mainframe . zOS.


I know all the above when I connect to DB2 on LUW ..
1. db2 select schemaname from syscat.schemata
2. db2 list tables for schema <schema name >
3. The defauult are SYSIBM SYCAT , SYSCAT . SYSFUN .

Can u please help me ...as I am connecting to the ZOS Db2 database
for the first time ,..and all the query fails .

Thanks a lot .

The fully qualified table names are in SYSIBM.SYSTABLES. In DB2 z/OS, the
table creator is equivalent to the table schema in DB2 for LUW.

Hi , Thanks a lot .
I was able to find all the creator i.e schema from sysibm.systools.
I hv 1 more question ...is their a way to get the tables of a schema
with out using the query "select name , creator from sysibm.systools
where creator='XYZ' ;

In normal case in LUW we use the command "db2 list tables for schema
<schemaname> . Is their any similar command in zOS DB2.

Thanks and Regards

Not as far as I know. On DB2 for z/OS, you're basically limited to
querying the system catalog for information (which wouldn't be a bad
thing if its system catalog was anywhere near as complete as the DB2
for LUW one - unfortunately it's not and there's several "warts" in
there too, e.g. the way view definitions are spread across several rows
in SYSIBM.SYSVIEWS).

On the plus side, the REMARKS columns in the z/OS system catalog permit
762 (?!) characters, beating the rather puny 254 character limit in DB2
for LUW :-). Still, it's not as much as the REMARKS columns in the
QSYS2 catalog on DB2 for i5/OS (2000 characters!) ... which has yet
another layout.

You can find the documentation for the z/OS catalog tables here:

P.S. If I sound a bit cheesed off at all differences it's because
they're causing difficulties for me in a small project. Deep breaths...
