Changing the SYSMAN Password.

In the good old days, you could just login to the repository database and use an ALTER USER SQL command to change the password of the SYSMAN user. In an object lesson of how to make things more complicated, here’s how you have to change the SYSMAN password now. There are two slightly different methods described below. One worked for OEM 12c R5 (you know the current SYSMAN password) and the other worked for OEM 13c R2 (you do not know the current SYSMAN password). These steps and others are described in more detail in MOS Doc ID 1365930.1:

OEM 12c R5 Method (you know the current SYSMAN password):

Locate the OMS_HOME directory:

[oracle@oraemcc ~]$ cd /u01/app/oracle/product/middleware/oms/bin

Shutdown the middle tier:

[oracle@oraemcc bin]$ ./emctl stop oms

Stopping WebTier...

Change the password:

[oracle@oraemcc bin]$ ./emctl config oms -change_repos_pwd

Stop the local Management Agent (just in case):

Stopping agent … stopped.

Ensure you can log into the SYSMAN_OPSS repository database account. Change the password using SQL*Plus if necessary:

SQL> connect sysman_opss/<your-SYSMAN_OPSS-pwd>@EMPDBREPOS
Connected.

SQL> show user
USER is "SYSMAN_OPSS"

Update the SYSMAN_OPSS password:

[oracle@oraemcc bin]$ ./emctl config oms -update_ds_pwd -ds_name sysman-opss-ds -ds_pwd <your-SYSMAN_OPSS-pwd>

Start the AdminServer and change the SYSMAN password:

Manually Remove Targets from the Repository.

From time to time you’ll need to remove targets and the Cloud Control GUI will complain, throw an error and invite you to contact Oracle Support. Like you, I have no time for that and fortunately there is a CLI method to achieve the desired outcome. Here’s a summary of the sub-programs within the MGMT_ADMIN package owned by SYSMAN (some are overloaded):

PROCEDURE ADD_TARGET_ADDITION_CALLBACK
PROCEDURE ADD_TARGET_DELETION_CALLBACK
PROCEDURE ADD_TARGET_DELETION_EXCEPTIONS
PROCEDURE CLEANUP_AGENT
PROCEDURE CLEAR_SITE_URL
PROCEDURE DELETE_OMS
PROCEDURE DELETE_TARGET
PROCEDURE DELETE_TARGET_ASYNC
PROCEDURE DELETE_TARGET_INTERNAL
PROCEDURE DELETE_TARGET_METRICS_1DAY
PROCEDURE DELETE_TARGET_METRICS_1HOUR
PROCEDURE DELETE_TARGET_METRICS_RAW
PROCEDURE DELETE_TARGET_SYNC
PROCEDURE DELETE_TARGET_WITH_MEMBERS
PROCEDURE DEL_TARGET_ADDITION_CALLBACK
PROCEDURE DEL_TARGET_DELETION_CALLBACK
PROCEDURE DEL_TARGET_DELETION_EXCEPTIONS
PROCEDURE DEREGISTER_TGT_DEL_MATCH
PROCEDURE DISABLE_METRIC_DELETION
PROCEDURE ENABLE_METRIC_DELETION
FUNCTION GET_MS_NAME RETURNS VARCHAR2
FUNCTION GET_OMS_DATA RETURNS REF CURSOR
FUNCTION GET_OMS_STATUS RETURNS NUMBER
FUNCTION GET_OMS_URLS RETURNS REF CURSOR
FUNCTION GET_SITE_URL RETURNS VARCHAR2
FUNCTION IS_METRIC_DELETION_ENABLED RETURNS NUMBER(38)
PROCEDURE REGISTER_TGT_DEL_MATCH
PROCEDURE SET_INACTIVE_TIME
PROCEDURE SET_LOG_LEVEL
PROCEDURE SET_LOG_PURGE
PROCEDURE SET_SITE_URL

In SQL*Plus, query the official name and type of the target you want to delete:

select target_name, 
       target_type                   
from   mgmt_targets 
where  target_name like 'orasvr02%';


TARGET_NAME                    TARGET_TYPE
------------------------------ --------------------
orasvr02.mynet.com             host
orasvr02.mynet.com:3872        oracle_emd

Delete the desired target:

exec mgmt_admin.delete_target('orasvr02.mynet.com','host');

To delete the Management Agent:

exec mgmt_admin.cleanup_agent('orasvr02.mynet.com:3872');
