Hi,
I am trying to install my copy of the DB2 Universal Workgroup
Server Edition on my Linux server (RedHat 9.0, kernel 2.4.20-6) and it
will not let me past the db2setup because of a Java error (which
doesn't make sense since I have installed version 1.5 which works). I
tried to get around it by using an earlier trial version of a DB2
Universal db which was running for 3 months until the license expired.
I figured that I could simply use that and install the licenses from my
Universal Workgroup Server Edition on top of the trial licenses. Well,
needless to say, it didn't work. Any suggestions? Pls advise. Thx.

It would be helpful to me if you could also post any response to my
email: odin@op.net

Here are some steps for installing on DB2 8.1 on RH9 that I have used. This
might work on other RH versions also:

DB2-RH 9 Linux Installation Instructions

1. Install IBM Java 1.4.2 (or latest code) free from IBM website.

2. Set display (where host_name is your host)
xhost + host_name
export DISPLAY=host_name:0

3. Set Kernel for DB2 install only (not needed later)
LD_ASSUME_KERNEL=2.2.5
export LD_ASSUME_KERNEL

4. Run ./db2setup
Install DB2 with an instance but DO NOT install Tools Catalog

5. Reboot

6. Update java path (your path may be different depending on which Java you
install). This will point DB2 to the correct JDK for DB2 and Admin Server.

db2 update dbm cfg using jdk_path /opt/IBMJava2-142
db2 update admin cfg using jdk_path /opt/IBMJava2-142

7. You can now install Tools Catalog in you want one.

8. Update Linux parms
The default setting for the msgmni kernel parameter only allows a couple of
simultaneous
connections to DB2. To set this value at boot time, append the following
lines to /etc/sysctl.conf:
# Sets maximum number of message queues to 128
# Set this to 1024 or higher on production systems
kernel.msgmni = 128

Hi,
IThe problem I am having is #4 db2setup. It chokes because of my
Java code. I have installed 1.5 from Sun (not IBM) and am working w/
it. It is just fine. Moreover I have checked the file which causes
the error and it purported tries to check the Java on my PC; if it
can't find it (which it can't) then it tries to use the version on the
CD (but can't). I have no idea why it can't use it's own version. Pls
advise. Thx.

Apparently, whatever version of Java you are using is not fine. Please
read the link I provided. I can't even find RH9 as a validated
environment for DB2 UDB V8.1. If you click the link on RHEL 3.0, you'll
find that even for RHEL 3.0, a workaround is recommended for using db2setup.

I told you what to do to make the install work. If you don't want to do
those things, that is up to you.

You can also bypass the Java installer entirely; just follow the
instructions listed in the DB2 HOWTO for Gentoo under "Installation
Notes": http://tldp.org/HOWTO/DB2-HOWTO/gentoo.html#AEN1134

You have to create your own users and groups, etc., but all of the
required instructions are there and it will get you going so that you
can actually work with the database

Unbelievable, just chging the xhost and LD_ASSUME_KERNEL seemed to do
the trick. At least I am past the db2setup error. Hopefully the rest
will be fine. I really appreciate your help. Thx soo mych.
