Hi everybody,

I'm trying now several days to get DB2 v8.1 up and running. Guess the installation was successful. But I'm not able to create an instance. I'm receiving always the same error independent from what I'm trying.

During the setup (db2setup) the creation already failed therefore I've tried it manually with the command (as root):

./db2icrt -a SERVER -s ese -u db2fenc1 -w 32 -p db2_db2inst1 db2inst1

Then I see the following lines:
Segmentation Fault - core dumped
Segmentation Fault - core dumped

Which doesn't looks too got to me. Don't know if this has an influence to the 'real' problem.

The log file looks like this:
--->
Program name = db2idbm
Instance home dir = /export/home/db2inst1, Sysadm group = root
Instance type = 1, Auth type = SERVER


Update DBM cfg SYSADM_GROUP errcode = 139
DBI1281E The database manager configuration file could not be
initialized.

Explanation:

An error occurred when attempting to initialize the database
manager configuration file. A DB2 instance could not be created
or migrated.

User Response:

Refer to the log file for problem determination. Resolve the
problem and try the command again. If the problem persists,
please contact IBM Support.

Of course I've searched through the internet and this forum but I wasn't able to figure out my problem.

I've also de-installed DB2 and then tried to install it again and I've used different users, etc. but always with the error mentioned above.

BTW, my knowledge of UNIX and DB2 is low but I need to get it running.

Please give me some advice to solve the problem.

Thanks.

Have you modified Solaris Kernal paramters prior to install DB2 ?
You will find details in Db2 install guide. Usually after making kernal changes you require to reboot server and then install db2 and create instance.

Hope this will help.

My kernel parameter should be fine. I've double checked this already.

Are there any other paramter that need to be set? Where else could the problem be? What do yot think I should do next to get around this problem?

BTW, I'd already installed v7.1 on that system and this worked fine.

Thanks.

It looks like permission problem. Check following before creating instance.

(1)The permission of /dev/null is incorrect. The instance owner needs to have write authority for /dev/null.

(2)The /tmp directory can't be written to by the instance owner.

(3) Make sure Instance home directory have enough space and read-write permission by instance owner.

(3)Log on as root rather than switching user as root and then rerun the db2icrt command.
