Online Patching Enablement patch: 13543062:R12.AD.C. ORA-44305: service ebs_patch is running ORA-06512: at "SYS.DBMS_SYS_ERROR", line 86 ORA-06512: at "SYS.DBMS_SERVICE", line 454 ORA-06512: at "SYS.DBMS_SERVICE", line 375 ORA-06512: at "APPS.AD_ZD_PREP", line 308 ORA-06512: at line 4 Checked the error message with oerr utility oerr ora 44305 44305, 0000, "service %s is running" // *Document : Yes // *Cause : The specified service was running. // *Action : This message is informational only. Actually the line 308 in package APPS.AD_ZD_PREP is where the error is happening. The line 308 in the package APPS.AD_ZD_PREP is executing the procedure dbms_service.start_service, as the service is already running the said error was thrown. So dbms_service.stop_service is executed explicitly to stop the service and adctrl is used to restart the failed worker. The adpatch continued to run and completed successfully.
