Installing IBM DB2 on Linux using IBM Installation Manager - Fun and Games

I've installed DB2 a million (!) times over the past 17 years, since I joined what was then IBM Software Group.

However, I've almost always installed it using the DB2 installation binaries and response files.

For a long time now, it's been packaged with IBM BPM, and other products, and thus suitable to be installed using IBM Installation Manager (IIM).

So now I'm trying that ….

One thing of which to be aware; DB2 is typically only ever installed as root, which means ( to me, at least ) that BPM etc. is also installed as root - which feels wrong.

But that's a challenge for another day.

I've got a response file to install WAS, BPM, DB2 etc., and am driving IIM as root (!): -

/opt/ibm/InstallationManager/eclipse/tools/imcl -input installBPM86_DB2_root.rsp -acceptLicense

Alas this failed with: -

ERROR: Error during "install" phase:
  ERROR: Installation of DB2 Advanced Workgroup Server has failed. 
  Installation failure reason: A fatal error occurred during the installation.

Thankfully, IIM keeps logs, lots of logs.

In my (root) case, these are here: -



ls -altrc /var/ibm/InstallationManager/logs

which makes sense …

cat /etc/redhat-release 

Red Hat Enterprise Linux Server release 6.6 (Santiago)

To check my hypothesis, I "cheated" by editing the above: -

Red Hat Enterprise Linux Server release 6.7 (Santiago)

and now things install happily :-)

/opt/ibm/InstallationManager/eclipse/tools/imcl -input installBPM86_DB2_root.rsp -acceptLicense

Installed to the /opt/ibm/WebSphere/AppServer directory.

DB21085I  This instance or install (instance name, where applicable: 
"db2inst1") uses "64" bits and DB2 code release "SQL11010" with level 
identifier "0201010F".
Informational tokens are "DB2 v11.1.0.0", "s1606081100", "DYN1606081100AMD64", 
and Fix Pack "0".
Product is installed at "/opt/ibm/WebSphere/AppServer/db2".

Of course, when I do this properly, I will use a supported version of RHEL, rather than "hacking" the redhat-release file …..
