Talk about running behind. I recently found out that Oracle does offer a client tools ONLY set for OBIEE. As of this writing (18.104.22.168.0), you can head over here and grab Oracle Business Intelligence Developer Client Tools Installer.
At a bit larger than 300 MBs, this download is a walk in the park compared to them 25 GBs.
I am successfully running Admin Tool now sans server on local box but I ran into a few odd things along the way.
1. Installing client tool goes smoothly until the end when installer states ‘completed with error’ message. Installer writes log to base of client tools directory, Oracle_Business_Intelligence_Enterprise_Edition_Plus_Client_InstallLog.xml
Here is the only error I found:
<action name="Custom Action" target="oracle.bi.CustomIAActionGetInstanceNumber" status="error">
For this, Google unusually gives/gave no results (yet?)
2. Upon opening rpd file in offline mode, I get the following error:
Disregarding this error proves the best idea since rpd opens file and I was able to proceed and work as intended.
Adding ORACLE_INSTANCE to what I believe is my valid path(C:\Program Files\Oracle\OBIEE Client\oraclebi\orainst\bifoundation\OracleBIServerComponent\coreapplication\repository), replaces that click-and-forget error with the following error:
Removing path brings back original one but allow me to open rpd again.
