To install DB2 9.1 on CentOS I had to do the following:
- install the correct java JDK from IBM (see previous posts)
- the db2prereqcheck gave me this error
ERROR:
The required library file libstdc++.so.5 is not found on the system.
Check the following web site for the up-to-date system requirements
of IBM DB2 9.1
I installed the following package with yum and prereqcheck passed:
yum install compat-libstdc++-33-3.2.3-61
After launching db2setup, the graphical install program came up and I went thru the screens with no problems.
Transferred fp5 code to system and ran installFixPack command which completed successfully.
I thought all was good, but that was wishful thinking. Issuing the db2start command resulted in the following error:
SQL1032N No start database manager command was issued. SQLSTATE=57019
To fix this, I went to /opt/ibm/db2/V9.1/instance and issued the command: ./db2iupdt [instance name]
ie.
./db2iupdt db2inst1
The db2start command was then able to start the database.
