Hi,
we're currently trying to test the HotStandby feature of MaxDB using
7.5.0.34 on SuSE linux.
Our scenario looks like this (minimal hardware requirements):
- server A: master instance with shared log-space via nfs
- server B: standby instance with mounted log-space via nfs
- data devspace is stored on local disks on each server
After enabling the master instance for HotStandby (db_offline and
hss_enable) it is not possible to bring the instance in
online mode. "db_online" fails with the following error:
2006-07-06 13:05:44 7809 ERR 13900 RTEHSS RTEHSS_API

2006-07-06 13:05:44 7809 ERR 20010 Admin ERROR '' CAUSED EMERGENCY
SHUTDOWN
Do we have a main configuration problem, and furthermore why does the
data devspace needs to be accessible for other hosts (I thought only the
log-space will be shared/used by all instances) ???
any help appreciated------------GERD----------------
