Good morning, listers, I am following the instructions found in "How To remove Workload Repository information related to an old DBID from workload repository (Doc ID 1251795.1)"; I realize it specifically says it is for "Release 10.2 to 11.2", but I am unable to find similar documents or instructions for 12c, so this is all I have available to me. My database is vanilla OSEE 12.1.0.1 on Solaris 10. When I attempt to unregister a database from AWR by DBID, I get the following error. SQL > exec dbms_swrf_internal.unregister_database(2595040291); BEGIN dbms_swrf_internal.unregister_database(2595040291); END; * ERROR at line 1: ORA-13553: operation failed - missing parameter [SRCDBID] ORA-06512: at "SYS.DBMS_SWRF_INTERNAL", line 193 ORA-06512: at line 1 However, this error does not jive with the description found in the package: SQL> desc dbms_swrf_internal ...

I have filed a case with Oracle but they are (VERY) slow to acknowledge it. So here is my question - what is the proper syntax? -- Charles Schultz
