Symptoms

While attempting to install DBConsole  aka  DBControl on ODA:

• you have multiple failures
• unable to install manually **
• unable to install running steps
• unable to install using a deployment

** COMMENT: This note is regarding a niche problem on the ODA which we have seen more than a few times:

 There are excellent notes on Manual installation and deinstallation for DBControl aka DBConsole you should be aware of:

Changes

 New or relatively new usage:

• The failure to create DBConsole can occur during the very first deployment
• This problem can also occur after a deployment which skipped the installation of DBConsole option
• The problem can actually be seen after a successful deployment (not recommended)
  
  

Cause

 ODA Dbconsole steps can fail many ways and places:

• Can be associated with the first attempt to install EM / DBconsole
• Can be associated with the removal of an instance after the installation of DBConsole
• Can be associated with RACone**
   this _might_ be a variation of the removal of one instance problem: i.e. the failure is not due to RACone, but how RACone and DBConsole was installed
• MISMATCHED or Mixed Case for Node Names between various locations required for a normal installation
  
  

Solution

 One possible Solution

For Support  

Track bugs similar to the following for current workarounds, fixes or basic problem diagnosis steps
- e.g. bug 16450280  

Did the customer ever remove an instance on either node?

Did they attempt to install EM while one instance or node was down

Have they manually made any changes to various files associated with Node names

Here are some places and diagnostic steps you might find useful

from our env: 
@ # grep DBCONTROL_HTTP_PORT test.log 
@ CONFIG: No value was set for the parameter DBCONTROL_HTTP_PORT. 
@ CONFIG: No value was set for the parameter DBCONTROL_HTTP_PORT_<node1>. 
@ CONFIG: No value was set for the parameter DBCONTROL_HTTP_PORT.

@ CONFIG: Setting param: DBCONTROL_HTTP_PORT_DC1ODA01P1 value: 1158  <<< UPPER case hostname     

^^^^^^^^^^

"...We re-configure the ODA with the bare metal V2.6.0.0.0 image, and use lower case letters in the hostname.
The installation is completed without problems, and de EM-console for the database runs correct.

Thank you for the solution !

This SR can be closed, and please update bug 16450280 with this solution.
