> 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.
