Resetting Referential Constraints if Data Purge Fails on DB2
If the Data Purge fails or is canceled by the user, there is a chance the referential constraints were not re-enabled. Use the following command sequence to enable them.
*To reset referential constraints
1. (Windows Only:) db2cmd (Skip this step if running on UNIX.)
2. db2 connect to[dbname] user [username] using [password]
3. db2 set path[Analysis Schema or Process Tracker Schema], SYSTEM
4. db2 set current schema [Analysis Schema or Process Tracker Schema]
5. Initiate the purge:
*Windows:
db2 call db_mgmt_modify_dependant_fk_constraints_all ('ENFORCED')
*UNIX:
db2 "call db_mgmt_modify_dependant_fk_constraints_all ('ENFORCED')"
