OEM 13cR3: Plugin Update on OMS : ONLINE

Now, in this blog I start with Plugin Update on OMS - but in Online manner
(Remember 2 steps for Online,Enable Online in Setup --> Provisioning & Patching --> Offline and set the credentials in Setup --> My Oracle Support --> Set Credentials)

So, now that you are ready 
Step 1 is to go to our good old page  Setup --> Extensibility --> Self Update  

(I will do my favourite here Oracle Database Plugin)
Select Plugins and Search for Oracle Database.

Select the "Available" Plugin and Click Download. 

Select Immediate

Click on Job Details and (Navigate to Job Details) Use  Refresh till the job completes

TIP: you can see the directory where it is downloading the patch. You can navigate to the directory and see the patch number if you want (nerds)



Next Go To Setup --> Extensibility --> Plug-ins 
Select the Plugin and Click Deploy on "Management Servers"

Click Next (Ensure you do the Pre-req check every-time - Best Practice)

Wait for the Pre-req to complete. 
If it fails one of the reasons might be 
EM13c : Plug-in Deployment Failed at "Install Software" Prerequisite Step (Doc ID 2455748.1)

Click Next and Enter the sys Credentials
You must ensure backup of DB and EM has been taken as specified

Click Next (OMS will go down in installation)

Now Monitor on the host using 

$ emctl status oms -details (emctl of MW Home)

Wait Till Completion depending on size the time varies - this one generally completes within 10-15 minutes.

One of the ways to grep for Status is to use a small script like this  - 

PWD=<sysman_password>
echo $PWD | emctl status oms -details | egrep 'Success|Running|Step'

And you will get output like this 

Step                                     Start Time                End Time                  Status

Preconfigure Management Repository       11/25/19 9:29:45 AM UTC   11/25/19 9:29:45 AM UTC   Success
Preregister DLF                          11/25/19 9:29:45 AM UTC   11/25/19 9:29:45 AM UTC   Success
Stop management server                   11/25/19 9:29:46 AM UTC   11/25/19 9:31:27 AM UTC   Success
Register DLF                             11/25/19 9:31:27 AM UTC   11/25/19 9:33:40 AM UTC   Success
Configure Management Repository          11/25/19 9:31:27 AM UTC   N/A                       Running
Configure middle tier                    11/25/19 9:31:27 AM UTC   11/25/19 9:34:52 AM UTC   Success

The last step generally is to Start OMS and Recover Middle Tier, OMS will come back up and you will have your OMS Plugin version update.

You can verify either from console or like this
$ emcli login -username=sysman
$ emcli sync
$ emcli list_plugins_on_server 

OMS name is vineet-sandbox:4889_Management_Service
Plug-in Name                                 Plugin-id                     Version [revision]
Oracle Database                              oracle.sysman.db              13.3.2.0.0
