The following post-apply actions are required of all current V9 customers. If you have already applied UK32047 and have performed the action for it, you need to take the following post-apply action only: (0) Bind the scheduler packages as follows: (a) Make a work copy of your updated customized copy of job DSNTIJSG. (b) Remove all job steps except DSNTIAS. (c) In job step DSNTIAS, remove all CREATE statements and remove the BIND PACKAGE command for member DSNADMCD. (d) Run the modified job to bind the scheduler packages. (e) When finished, you can erase the work copy of the job. For data sharing, this action needs to be performed only once for the group. If you have not yet performed the post-apply actions for UK32047, you need to take the following post-apply actions for this PTF: (1) Update private copies of the installation CLIST This PTF modifies the DB2 installation CLIST members

DSNTINS1 and DSNTINS2 in the prefix.sdsnclst target library. After applying this PTF, you need to redo any record format changes and reapply any tailoring you have done to your copies of DSNTINS1 and DSNTINS2. You may also want to move them to the prefix.new.sdsnclst data set, where the CLISTs processed by job DSNTIJVC reside. (2) Update your customized copy of job DSNTIJSG (a) Edit your customized copy of DSNTIJSG (b) Add the following SQL statement under the SYSIN DD of job step DSNTICU. If DSNTICU is commented out then you should also comment out this statement: DROP PROCEDURE SYSPROC.ADMIN_TASK_ADD RESTRICT; (c) In job step DSNTIAS, make these changes to the CREATE statement for procedure SYSPROC.ADMIN_TASK_SCHEDULE: - Change the procedure name to SYSPROC.ADMIN_TASK_ADD - Change,IN TRIGGER_TASK_ID INTEGER to,in TRIGGER_TASK_NAME VARCHAR(128) - Change,OUT TASK_ID INTEGER to,inout TASK_NAME VARCHAR(128) (d) Also in job step DSNTIAS, make these changes to the CREATE statement for procedure SYSPROC.ADMIN_TASK_REMOVE - Change TASK_ID INTEGER to IN TASK_NAME VARCHAR(128) (e) Also in job step DSNTIAS, make these changes to the CREATE statement for function DSNADM.ADMIN_TASK_LIST: - Change,TRIGGER_TASK_ID INTEGER to,trigger_task_name VARCHAR(128) - Change,TASK_ID INTEGER to,task_name VARCHAR(128) (f) Also in job step DSNTIAS, make these changes to the CREATE statement for function DSNADM.ADMIN_TASK_STATUS: - Change TASK_ID INTEGER to TASK_NAME VARCHAR(128) - Add,SQLERRMC VARCHAR(70) between,sqlerrp VARCHAR(8) and,db2_ssid VARCHAR(4) (g) In job step DSNTIJG, change the GRANT EXECUTE statement on procedure SYSPROC.ADMIN_TASK_SCHEDULE to SYSPROC.ADMIN_TASK_ADD. If you do not already have the routines ADMIN_TASK_SCHEDULE, ADMIN_TASK_REMOVE, ADMIN_TASK_LIST and ADMIN_TASK_STATUS and the scheduler configured in your DB2 V9.1 for z/os, you can skip the following section. Otherwise, to activate the changes in this PTF you need to take the following additional actions: (3) Stop the scheduler for administrative tasks. (4) Replace the interface in DB2.

(5) Stop and restart db2. (6) Migrate the currently defined scheduler tasks. (7) Adapt the applications. Each of these actions is detailed below. Note that DB2 must be running. (3) If the scheduler is running, stop it first by executing following console command: modify dsnadmt,appl=shutdown where dsnadmt is the name of the scheduler. (4) Create, bind, and grant access to the stored procedures and functions for the administrative scheduler. For data sharing, this action needs to be performed only once for the group: (a) Make a work copy of your updated customized copy of job DSNTIJSG. (b) Uncomment step DSNTICU, remove all job steps except DSNTICU, DSNTIAS and DSNTIJG. (c) Remove all DROP statements from step DSNTICU except the following: DROP PROCEDURE SYSPROC.ADMIN_TASK_SCHEDULE RESTRICT; DROP PROCEDURE SYSPROC.ADMIN_TASK_ADD RESTRICT; DROP PROCEDURE SYSPROC.ADMIN_TASK_REMOVE RESTRICT; DROP SPECIFIC FUNCTION DSNADM.ADMIN_TASK_LIST RESTRICT; DROP SPECIFIC FUNCTION DSNADM.ADMIN_TASK_STATUS RESTRICT; (d) In job step DSNTIAS: - remove the BIND PACKAGE command for member DSNADMCD - remove all CREATE statements, except the following: CREATE PROCEDURE SYSPROC.ADMIN_TASK_ADD... CREATE PROCEDURE SYSPROC.ADMIN_TASK_REMOVE... CREATE FUNCTION DSNADM.ADMIN_TASK_LIST... CREATE FUNCTION DSNADM.ADMIN_TASK_STATUS... (e) Remove all GRANT statements from step DSNTIJG except the following: GRANT EXECUTE ON PROCEDURE SYSPROC.ADMIN_TASK_ADD TO PUBLIC; GRANT EXECUTE ON PROCEDURE SYSPROC.ADMIN_TASK_REMOVE TO PUBLIC; GRANT EXECUTE ON FUNCTION DSNADM.ADMIN_TASK_LIST TO PUBLIC; GRANT EXECUTE ON FUNCTION DSNADM.ADMIN_TASK_STATUS TO PUBLIC; GRANT EXECUTE ON PACKAGE DSNADM.DSNADMTA TO PUBLIC; GRANT EXECUTE ON PACKAGE DSNADM.DSNADMTR TO PUBLIC; GRANT EXECUTE ON PACKAGE DSNADM.DSNADMTU TO PUBLIC; GRANT EXECUTE ON PACKAGE DSNADM.DSNADMTL TO PUBLIC; GRANT EXECUTE ON PACKAGE DSNADM.DSNADMTS TO PUBLIC; GRANT EXECUTE ON PACKAGE DSNADM.DSNA6DB2 TO PUBLIC; GRANT EXECUTE ON PACKAGE DSNADM.DSNA6THP TO PUBLIC; You can of course replace keyword PUBLIC with a more restrictive set of grantees, as they are currently defined in DB2. (f) Locate the WLM ENVIRONMENT clause in each of the CREATE PROCEDURE and CREATE FUNCTION statements in job step DSNTIAS and change WLMENV6 to the WLM environment for running these routines, as they are currently defined in DB2. Make sure that in the WLM procedure used to start the address space where these stored procedures are running, all libraries in the STEPLIB DD concatenation are APF authorized. (g) Run the modified job to create the new objects, bind

the new packages, and grant access. (h) When finished, you can erase the work copy of the job. (5) Stop and start DB2. This action will also start the DB2 administrative task scheduler if zparm ADMTPROC specifies a valid, non-null setting. (6) No task migration is needed. The tasks that were present in the scheduler before installing this PTF are still available afterwards. You can list them using the table function ADMIN_TASK_LIST, a task with a previous TASK_ID of 1 is listed under the TASK_NAME of "TASK_ID_0001". If you want to change the name of the task you have to remove the task and add it again with another name. (7) Modify any application that calls one of the stored procedures or functions of the scheduler. The changes in the interface are explained elsewhere in this PTF.).

If your site does not use the DB2 Universal JDBC Driver or the CLI Driver shipped with DB2 for Linux, Unix, and Windows, then these stored procedures are likely not used so the following instructions would be unnecessary. However if these stored procedures are used at your site and the following instructions are not followed, SQL errors may result, particularly SQLCODE -805 or SQLCODE -443. After applying this PTF, the packages associated with these stored procedures must be bound from the updated DBRMs. There are two ways to do this: 1. Re-run the installation job for those stored procedures. That installation job is named DSNTIJMS and it resides in db2-prefix.sdsnsamp. The customization instructions are inside the job itself. While this option can be more convenient, it may perform additional activity that can impact concurrently-running applications. The customization instructions in that job indicate that if you are re-running the job, you should uncomment the first step, which pre-drops all the objects (procedures, temporary tables, indexes). If there are application using the procedures, or that have statements or packages that are dependent on the indexes, the applications or the installation job might be unable to complete normally. 2. Create and submit a job to just bind the affected packages. Following is the BIND command that should be used. Replace the DSN!!0 in the command with your

high-level dataset qualifier for the target DB2 subsystem: BIND PACKAGE(DSNASPCC) MEMBER(DSNACPR8) - ACTION(REPLACE) ISOLATION(UR) QUALIFIER(SYSIBM) - RELEASE(COMMIT) SQLERROR(CONTINUE) ENCODING(EBCDIC) - LIBRARY('DSN!!0.SDSNDBRM') BIND PACKAGE(DSNASPCC) MEMBER(DSNACOL8) - ACTION(REPLACE) ISOLATION(UR) QUALIFIER(SYSIBM) - RELEASE(COMMIT) SQLERROR(CONTINUE) ENCODING(EBCDIC) - LIBRARY('DSN!!0.SDSNDBRM') BIND PACKAGE(DSNASPCC) MEMBER(DSNATBP8) - ACTION(REPLACE) ISOLATION(UR) QUALIFIER(SYSIBM) - RELEASE(COMMIT) SQLERROR(CONTINUE) ENCODING(EBCDIC) - LIBRARY('DSN!!0.SDSNDBRM') BIND PACKAGE(DSNASPCC) MEMBER(DSNATBL8) - ACTION(REPLACE) ISOLATION(UR) QUALIFIER(SYSIBM) - RELEASE(COMMIT) SQLERROR(CONTINUE) ENCODING(EBCDIC) - LIBRARY('DSN!!0.SDSNDBRM') These packages were built using the VERSION option. This means that submitting these binds after this PTF was applied, but before DB2 or the WLM address space has been restarted will create the new version of the packages but will leave the old version, allowing the stored procedures to continue running with the old procedure load modules and packages until DB2 or the WLM address space is restarted.).
