I often have the same problem on my laptop and have to restart the services. In my case, the root cause is that the Oracle TNS listener service goes to sleep when I suspend my laptop and does not wake back up. When this happens, I restart my services in this order:
- Oracle database (only if it is not running)
- Oracle TNS listener
- OpenLDAP
- Shared Services
- Essbase Admin Services server
Once this is complete, I have no problems logging in. I am sure that if I had the Oracle piece running on something other than a laptop, I would not see these issues either.
The user also had some other questions relating to the app server / web server terminology in the Oracle docs. The embedded Tomcat server is the app server that is shipped out of the box. I expect that to change in the future due to the Oracle acquisition of WebLogic.
He also asked about the role of Microsoft IIS in the equation. IIS is not used in the Essbase stack (OpenLDAP / Shared Services / Essbase / Essbase Administration Services / Essbase Integration Server / Analytic Provider Services). I believe that some portions of the other Hyperion products may need it.
