Running Multiple Oracle Instances
I have created 2 instances under Oracle 8.1.7 HP-UX 11 and am trying to get them both started. I can start either database on its own without problems, but as soon as I try to start the second database (after changing oracle_sid I start svrmgr and do connect internal then startup) I get the following error:
SVRMGR> startup
ORA-03113: end-of-file on communication channel
As I can start this database if the other one is not running I think that there must be something worng with my Unix environment - has anyone any ideas.
Thanks in advance, Eddie
PS - I even tried using dbstart - output is attached FYI.

Re: Running Multiple Oracle Instances
You should check your kernel parameters.
Your SHMMAX should be larger than 1 GB.
Pls check also for HP patch PHSS_22478.
Try to get the installation guide from Oracle TechNet or Metalink. The Installation Guide there is for Oarcle 8.1.5 ithink, but the parameters in this will be ok.

Re: Running Multiple Oracle Instances
Windows? software to create multiple SGAs, each of which can be upto 1.75GB
in size.
Check Large SGA support for HP, Memory Windows, for a more details.
HP-UX patches and an Oracle 8.1.7 patch are required. Note that the Oracle
patch will NOT be backported to earlier releases.
Have a thorough look at this attached doc.

Re: Running Multiple Oracle Instances
I suspect that this is related to memory.
- What are the SGA sizes of your two databases?
- Is shmmax configured large enough to cope with both SGA's?
- Do you have sufficient swap space to cope with both SGA's etc.
Hope this helps.
