Rational Workbench for CLM setup

Is there any place to find whole setup documentation from first steps to deploying first templates?

I created four db2 databases:

jazz, rtc, rqm and rdm. I customized teamserver.properties files for each of this databases.
After that, I run repotools for creating tables for all of databases.
After that, I started Jazz team server and followed these steps:

https://jazz.net/wiki/bin/view/Main/CommonProjectAdminSetup

I successfully logged in RTC setup and RQM setup (as described in first steps of link I mentioned), but in RDM setup (step 6),

I got this message:

You are not authorized to access the Jazz Team Server Admin UI.

Why this happened?

I can't follow further steps without this.

Is there something what I am doing wrong?

P.S. As I mentioned RQM, when using DB2, I needed to create this database with PAGESIZE 16k, and all others with PAGESIZE 8k. Also, at RQM database, I needed to increase buffer pool size. While I didn't do these steps, I wasn't able to run repotools -createTables.
