Db2 for z/OS

Drop indexes with uniquerule P and C

When a tablespace is converted from PBG to PBR or even PBR-PBG-PBR all indexes become non-partitioned. There will not be a solution to convert non-partitioned indexes to partitioned. Instead IBM point to DB24ZOS-I-553 to create new unique indexes ...

Removed object types after Db2 13

At IDUG in Valencia Haakon Roberts informed us that some object types and a few other things has to be removed before we can go to the version after Db2 13. These are Simple tablespaces Segmented Tablespaces Classic partitioned tablespaces Basic (...

Allow alter column to drop NOT NULL constraint

Currently the only way to remove the NOT NULL constraint from a column is to unload the table, drop-recreate table (or drop-add column) and reload table. Such a small change needs so much effort, and causes unnecessary outage and service disruptio...

Add support for GRANT ROLE to AUTHID.

In DB2 for z/OS I am allowed to CREATE ROLE, GRANT priviledges to ROLE but I can't GRANT that role to a USERID. Seems something is broke to me. What are ROLES good for if I can't assign a user or group of users to that role.

Improve ALTER TABLE ROTATE PARTITION

Currently ALTER TABLE ROTATE PARTITION only allows the ENDING value to be a constant, minvalue, or maxvalue. I would suggest adding the ability to generate DATES or TIMESTAMPS so that additional programming is not necessary to generate the ALTER s...

Enhanced Instrumentation for workfiles

A possibility through IFI and/or a new command -DIS WORKFILES to get an “asis” use list of all work pools (Sort , DGTT, Work etc.) This data is crucial for tuning the number, size and type of the work spaces that we all have. The output should be ...

IRLM enhancement in case of global deadlock processing

We had a situation which was described in case TS015567644. The symptom was that IRLM could not fully process the complete deadlock stuff of all members of an 8-way DS system. Therefore we get DXR167E in some of the members. Additional workload wi...

allow CREATE TABLE LIKE another table and propagate table partition limits

Today, it is possible to create a PBG tablespace and then use CREATE TABLE like another table and the new table is in the new ts. CREATE TABLESPACE ZPOLCL IN DDB01P SEGSIZE 64; CREATE TABLE TPOLCL LIKE DBCCLP1.TPOL IN DDB01P.ZPOLCL; If the source...

ALTER TABLE DROP multiple COLUMNs

If you want do delete multiple columns of a table using "ALTER TABLE tbname DROP COLUMN colname", you currently have to execute many ALTER TABLE statements. The execution time increases exponentially with the number of columns to be deleted. If th...

Stop package invalidation after ALTER MAXPARTITIONS

These days in an agile world we have to ALTER PBG spaces on-the-fly to raise the MAXPARTITIONS value. Sadly this ALTER, even though it is an immediate ALTER, sets all dependent packages to VALID = 'N' which is, of course, a disaster.
