Change BDA Cluster Name in OEM Cloud Control 13c

Oracle OEM Cloud Control 13c has some improvement than OEM 12c. But for BDA, the most weird thing after OEM BDA Discovery is the target name for BDA cluster. By default, the target name is called BDA Network 1 for the first BDA cluster, and BDA Network 2 for 2nd BDA cluster. Think about this way, Oracle BDA already has a different BDA cluster name than Cloudera Manager’s cluster name. Right now OEM comes out with another different cluster name. If we have two BDAs and use OEM 13c to discover the DR BDA first, the DR BDA will take BDA Network 1 name. Then primary BDA will be discovered as BDA Network 2. It’s really an annoying new feature in OEM 13c. Ideally, I want to change the BDA Network Name to something meaningful. BDA Network 1 is really an useless naming standard, just like the door below. Mapping to either BDA cluster name or Cloudera Manager’s Cluster name is fine with me. In this blog, I am going to discuss whether I can change this name to something I like.

There are two types of targets in OEM: Repository Side Targets and Agent Side Targets. Each managed target in OEM have a Display Name and Target Name. So for BDA Network, I am wondering which category is for this target.

Run the query for Repository Side targets:

Ok, we can see entity_type is oracle_bda_cluster for BDA Network. Both target name and display name are BDA Network 1.

Next, I will check whether I can rename the target name of BDA Network 1. I used emcli rename_target command in the past to rename OEM target. It usually works. So I run the following command:

[oracle@enkx4bdacli02 ~]$ emcli show_bda_clusters
BDA Network 1 : enkx4bda

[oracle@enkx4bdacli02 ~]$ emcli get_targets -targets="oracle_bda_cluster"
Status  Status           Target Type           Target Name                        
 ID                                                                               
-9      N/A              oracle_bda_cluster    BDA Network 1  

[oracle@enkx4bdacli02 ~]$ emcli rename_target -target_type="oracle_bda_cluster" -target_name="BDA Network 1" -new_target_name="X4BDA"
Rename not supported for the given Target Type.

No luck. It doesn’t work. If renaming target name not working, let me try to change display name.

[oracle@enkx4bdacli02 ~]$ emcli modify_target -type="oracle_bda_cluster" -name="BDA Network 1" -display_name="X4BDA"
Target "BDA Network 1:oracle_bda_cluster" modified successfully

It works. Rerun the query to check oracle_bda_cluster type.

Well it work partially. For some screens, it works perfectly.

But for some other screen, it still shows the same annoying name.

Another lesson I learned recently is that you need very careful in using default password when setting up BDA. Once setting up BDA using default password and OEM BDA Discovery is using these default password for Named Credentials, you will run into issue after you change default password later on. In the worst case, like Cloudera Manager’s password change, it requires the remove the current BDA target and redo the BDA Discovery. I may write this topic in a different blog if I have time.
