oninit: Fatal error in shared memory initialization

Posted By: Kokane Rajesh, IBM
Date: Wednesday, 15 January 2003, at 1:40 a.m.

Hi,

We have Production system & DRS system ( OS : AIX 4.3). We take the backup
of prod system, clone it and send to drs site for restoration. Both system
have same hardware except physical memory, prod system have 5.5 gb memory
and drs have 2 gb memory.

Last Sunday, we upgraded the Informix ver. 7.24 UC3(32bit) to 7.31FD2x1
(64bit) successfully on prod system and then we took the database backup,
file system backup of /informix/CD1(contains config/bin files of informix),
/home/informix (home path of informix) and sent to drs site.

We have restored the file system backup on drs system and then restored the
database, but when I try to bring the database into online mode it gives
error of shared memory. In the online log file it gives the following
error. I have checked the sqlhosts.soc, /etc/services file, onconfig file
setting on both system, all are identical. Since upgradation , I have
restored twice the prd system backup on drs system.

When I restored the database on drs, it brings the drs system in fast
recovery check point reqd. mode. But same time in the online log file it
shown restoration completed.

I killed all shared memory segment by IPCRM command, restarted the server ,,
but still giving the same problem.

Error when I run the oninit command to bring the system online.

oninit: Fatal error in shared memory initialization

Error in online.log file

10:48:53 Event alarms enabled. ALARMPROG = '/informix/CD1/etc/no_log.sh'
10:48:58 DR: DRAUTO is 0 (Off)
10:48:58 AIX MP latch code enabled
10:48:58 Informix Dynamic Server Version 7.31.FD2X1 Software Serial Number
ACN
#J349349
10:48:58
10:48:59 Logical Log File not found.
10:48:59 Informix Dynamic Server Stopped.
10:48:59 mt_shm_remove: WARNING: may not have removed all/correct segments

There is no problem on production system.

My question :
1. Do I need to initialize the database and restore the database ?
2. Is it because of less physical memory on drs system ?

Regards

Rajesh Kokane
