PH07660: ADD PRE-MIGRATION QUERY TO DSNTIJPM TO IDENTIFY STORED PROCEDURETHAT'D INCUR AUTOBIND AT FIRST USE.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This apar adds a query to DSNTIJPM to report native stored
  procedures and non-inline SQL functions created in V9 or
  earlier that can incur autobind(autbndxx service task)
  at first use. The many autobind service tasks can deadlock
  with each other and interfere with other jobs.

  1. Native SQL procedures and compiled SQL scalar functions
  created in Db2 9 need to be explicity alter regenerated
  in order to avoid ongoing implicit regeneration by Db2
  after migrating to Db2 12. However, the Db2 12
  pre-migration checkout jobs DSNTIJPM (in Db2 12) and
  DSNTIJPC (in Db2 11) do not provide any reports to
  identify such action.
  2. Private copies of the DSNTIDxx CLIST member may have a
  STATCLGSRT entry with a DS SCP (data sharing scope) value
  of 'G', instead of 'M'.
  

Problem conclusion

• 1. This APAR adds a new report (REPORT23) to Db2 12
     pre-migration checkout jobs: DSNTIJPM (in Db2 12)
     and DSNTIJPC (in Db2 11).
  
     These jobs use the following query
  
        SELECT CASE ROUTINETYPE
               WHEN 'F' THEN 'FUNCTION'
               ELSE 'PROCEDURE'
             END
           , RTRIM(SCHEMA) || '.' || RTRIM(NAME)
           , RTRIM(SCHEMA) || '.' || RTRIM(SPECIFICNAME)
           , RTRIM(VERSION)
        FROM SYSIBM.SYSROUTINES
         WHERE RELCREATED = 'M'
         AND (ORIGIN = 'N'
          OR (ORIGIN = 'Q' AND INLINE='N'))
       ORDER BY ROUTINETYPE, SCHEMA, SPECIFICNAME
  
     to generate REPORT23 which identifes all native SQL
     procedures and compiled SQL scalar functions which were
     created in Db2 9. The routines listed in this report need
     to be alter regenerated explicitly before beginning
     migration to Db2 12, immediately after migration to
     Db2 12, or after migration to Db2 12 if you have not
     performed such action yet.
  
     The following example SQL shows how to alter regenerate a
     native SQL procedure:
  
        ALTER PROCEDURE schema.name
        REGENERATE VERSION version-id
  
     The following example SQL shows how to alter regenerate a
     compiled SQL scalar function:
  
        ALTER SPECIFIC FUNCTION schema.specificname
        REGENERATE VERSION version-id
  
  2. This APAR also adds a HOLD action for users who
     maintain private copies of the DSNTIDxx CLIST
     member to change their STATCLGSRT DS SCP setting to
     'M', if it is currently 'G'.
