The error on the log files refers to a problem with an index
Caused by: java.sql.SQLException: [CA Clarity][Oracle JDBC Driver][Oracle]ORA-01502: index 'NIKU.CMN_SEC_ASSGND_OBJ_PERM_PK' or partition of such index is in unusable state
ORA-06512: at "NIKU.CMN_SEC_ASSIGN_INST_RIGHT_SP", line 76
ORA-06512: at line 1
This is an Oracle DB issue:
An attempt has been made to access an index or index partition that has been marked unusable by a direct load or by a DDL operation
1. Make a DB backup.
2. Stop the Clarity services
3. On the database side, rebuild the affected index(es) using the command below as an example:
alter index <index name> rebuild
On your case: alter index CMN_SEC_ASSGND_OBJ_PERM_PK rebuild
4. Restart the Clarity services
Rebuilding the affected index might complain about the following index and so on.
If you find yourself in this scenario, you might need to rebuild all indices.
