Hi,
I'm having a hard time getting ESE 8.1 to run on a freshly installed
SuSE 9.0 linux box. It was actually up and running, but after a reboot
(one disk in the RAID 5 had to be replaced) it wouldn't start, saying
SQL6048N (communication error, see below).
As it was a test installation on a newly installed server I decided to
throw the DB2 installation away and start again (uninstalling DB2 and
removing everything DB2-related from /etc/, /var/db2 and /opt, and
removing the DB2 specific users).
Now, unfortunately, whenever I install from scratch and try to create an
instance, db2icrt complains about
SQL6048N A communication error occurred during START or STOP DATABASE
MANAGER
processing.
Update DBM cfg SYSADM_GROUP errcode = 8
DBI1281E The database manager configuration file could not be
initialized.
(from db2icrt.log.xxxx)
I've tried quite a lot - if not all - possible combinations of
- using db2setup or db2icrt to create instances
- letting db2setup create the users, or create them beforehand
- making sure that rsh works for the instance owner and for root
(although I'm not trying to install a multi-node database)
- making sure that all DB2 users have write permissions in their homes
- increasing the numbers of IPC resources via /proc/sys/kernel/shmmax
etc.
Older threads in this group point to potential problems with
/etc/services, but it looks like the installer set up a range of ports:
DB2_db2inst2 60000/tcp
DB2_db2inst2_1 60001/tcp
DB2_db2inst2_2 60002/tcp
DB2_db2inst2_END 60003/tcp
Maybe someone has an idea of what's going wrong here?
Thanks a lot in advance,
Christoph Schmitz
