setting up non-root DB2 instance on RHEL5

Jeff Taylor (76●7●3) | asked Feb 26 '09, 11:05 a.m.
I am trying to setup RTC server and DB2 Express on a RHEL5 machine. I am trying to complete the installation as a non-root user and have run into a snag.

I used the Install Manager to install the packages from the downloaded zip file of RTC Standard. Following the instructions, I used the launchpad to start db2setup to install DB2 Express.

The instructions mention to take note of the userID, password, and port. The only information I received from the installation was the port number. I can only assume that the userID is my own, db2admin, or db2inst1.

The steps for setting up the DB2 database, say that I should use an account that have sysadmin authority on the DB2 database. The is a tip that says to sudo to db2fenc1.

I do not have access to sudo on this machine. Should it matter if I am trying to do a non-root install? Is there a way around this by configuring the database?

In any case, I proceeded to run the "db2 create" command without problems. Afterwards, I run into problems trying to run the "repotools.sh -createTables" command. It complains about not being able to connect to the database without root access.

Any help would be appreciated.

Thanks,
Jeff Taylor

Yes, the userID is your own.

That tip is applicable when DB/2 is installed as root. You will not
need to use sudo when doing a non-root install.

In any case, I proceeded to run the "db2 create" command
without problems. Afterwards, I run into problems trying to run the
"repotools.sh -createTables" command. It complains about
not being able to connect to the database without root access.

Unfortunately, there is still one step that has to happen as a root
user. A root user has to run the db2rfe command to enable
authentication. If you're able to do this, the steps are:

1. Edit /home/<userid>/sqlllib/instance/db2rfe.cfg
Set ENABLE_OS_AUTHENTICATION=YES

2. As a root user:
cd /home/<userid>/sqlllib/instance
./db2rfe -f db2rfe.cfg
