Hello,

Any specific reason you want to remove just the Database System (suffix_sys) target? When the related Database Target is removed from OEM Cloud Control the system target is removed automatically.

Warning

You have chosen to remove the target SID (Database Instance). This database target is associated with database system and service. Removing the database target will delete the following associated targets. Do you want to proceed?

• Database System (SID_sys)
• Database Services (4)

Regards,

Satya

Hi,

You can not remove the 'database system' (e.g ORCL_sys) target only. If you try to remove the 'database system' target it will remove the other member targets within it and you will see the following message before proceeding:

You have chosen to remove the target ORCL_sys (Database System). This database system has database target ORCL (Database Instance) as key member. The database target will also be removed if the database system is removed. Do you want to proceed?

For more information about 'database system' target see  Doc ID 1543605.1: EM 12c, EM 13c: Understanding the Database System (oracle_dbsys) Target in Enterprise Manager Cloud Control 12c and 13c

Did you tried using emcli from the OMS server?

You can simply remove a target as following from target home page. in the example below Oracle Database is member of  ORCL_sys database system target. This screen is from 13c, but it is same for 12c as well.

Hi,

Could you please give us some more information? You have a database system with 'x' number of members. Could you please provide a listing of members (And their target types) and also indicate which member you want to remove?

Thanks

Ian

You can delete a target using emcli:

1)Login to EMCLI from your OMS server

emcli login -username=sysman -password=XXXXX

2)Then sync your targets:

emcli sync

3)Get the list of targets

emcli get_target

4)To delete an agent and its targets

$ emcli delete_target -name=”target_host_name:3872″ -type=”oracle_emd” -delete_monitored_targets

Note: The above deletes the Agent and ALL its monitored targets from the repository.

• "-delete_monitored_targets" : Delete the targets monitored by the specified Management Agent. Applicable only with the oracle_emd target type.

5) To delete a specific target:

$<EMCLI_HOME>/emcli delete_target -name="<target_name>" -type="<target_type>"

Example:

  $./emcli get_targets -targets="DBname:oracle_database"

  $./emcli delete_target -name="DB1" -type="oracle_database" -delete_monitored_targets -async
