Error while installing DS EE on AIX

Hi All,
I am trying to install DS 7.5.1A ( Enterprise Edition) on an AIX env. Half way thru I get an error like this:

[DataStage Server 7.5.1A - Installation and Maintainance Utility]

ERROR: Installing DataStage server engine failed - see below
########################################

Initializing unohist file
uvregen: reconfiguration complete, disk segment size is 6924252
Booting engine version 7.5.1.2 instance "ade"
Error occurred during -admin -reset execution.
Install of DataStage Engine aborted.
########################################

I am doing the install under a non-root id.

Could this be the problem. Do I have to do the install with root priveleges?

Any help would be greatly appreciated.

~M

Welcome aboard. Reading your installation instructions will help you greatly. You've probably missed most of the important steps to do prior to an installation, such as verifying and adjusting kernel parameters, installing/verifying your compiler, and setting up the appropriate installation userid and groups.

Read the installation steps that came on the install CD, because to help you we would just paste the document here rather than retype all of the pre-install steps. If you get stuck, get back to us. :D

Hi KC,
I have read the installation steps and followed each one of them. Checking for shared memry settings etc...

I have the same recurring problem.

the error is the same. Initially I forgot to set the $DSHOME which i set in my .profile ( under the id I am runnig the installtion under.) I looked at the error log file,its more cryptic the last lines are the same as the error I posted in my first message.

I got the sysadmin to run the install under root, its the same error.

Called DS support , they asked me remove the dsinstall dir from /tmp and run the install again( after doing an uninstall). Same error.

The C compiler I have is : IBM(R) XL C Enterprise Edition V7.0

I note that uvregen is trying to generate a shared memory segment 6,924,252 bytes in size. Usually this shared memory segment is under 1MB. Please check that this large size of shared memory segment is possible on your system. Most UNIX systems have the kernal parameter SHMMAX, but AIX has more self-tuning in its kernel - you will need to check with your UNIX System Administrator. If this size of shared memory segment is not supported, you will need either to increase what permitted or to reduce the size of some of the tunables in uvconfig, or the memory offsets for the other shared segments.

The problem was the shared memory setting was somehow not showing.
ipcs -m does nto show any shared memory values. DS support had asked us to reboot the server and ipcs -m does show shared memory settings after bouncing the AIX box.

I was able to complete the installation after.
Thanks all for ur suggestions and help.

Regards,
M
