OBIEE 12c Online RPD modification : BI Server Password corruption
We have noticed that the BI Server goes down some times and does not come up after carrying out online RPD changes.
During the online edit looks like the RPD password is getting corrupt and causing the BI server errors
We worked a way to overcome this issue by restoring the default RPD and then deploying the latest version of the RPD. Of course you do need the latest offline RPD to hand to use this method.
The detailed steps are

We worked a way to overcome this issue by restoring the default RPD and then deploying the latest version of the RPD. Of course you do need the latest offline RPD to hand to use this method.
The detailed steps are
- Navigate to the directory /Middlewarehomebi12/user_projects/domains/bi12/bitools/bin and issue
- Delete liverpd.* and all other versions of RPDs in the directory /Middlewarehomebi12/user_projects/domains/bi12/bidata/service_instances/ssi/metadata/datamodel/customizations
- Clear the content of file default_diff.xml in the directory /Middlewarehomebi12/user_projects/domains/bi12/bidata/service_instances/ssi/metadata/datamodel/customizations/default
Note: Do not delete this file
- Issue the command sh start.sh to start all services from bitools/bin directory
- The system should come up with default RPD
- Login in to Weblogic as weblogic user to ensure all services are up and running
Now we need to deploy the latest RPD
FTP the RPD to the server and issue the following command from /bitools/bin directory
sh data-model-cmd.sh uploadrpd -I <Mylatestversion>.rpd -W <RPD Password> -SI ssi -U weblogic -P <weblogic password>
Hope you don't face this issue but if you encounter an error like here then you can use the above approach.
[Server failed to start up but Node Manager was not aware of the reason]. Please check Node Manager log and/or server 'obis1' log for detailed information.]. Please check Node Manager log for details.
