Hello, I try to up my informix server and I have this error

oninit: Cannot open chunk ''. errno = 2

oninit: Fatal error in shared memory initialization

I don't konw what to do. may you help me?

Oops, it seems one of your chunks/disks is being offline. There should be more info in your logfile (See MSGPATH parameter in your onconfig file).

If it wasn't your rootdbs there a big chance IDS has marked it down, only way to recovery in that case is a restore.

If you want more advice, please post the last 100 lines or so from you log file and the output of oncheck -pr (this still works even if the engine is down, it will be only very very slow (could take several minutes)).

If your rootdbs was unavailable then you could be lucky....

Hope this helps,

This is the whole error.

Where is the file ONCONFIG?

Please check if you have correct value
for ROOTPATH variable in onconfig file.
This error is reported when oninit process fails to open
a file(root chunk) mentioned in ROOTPATH.
onconfig file is generally located in $INFORMIXDIR/etc/$ONCONFIG, where INFORMIXDIR and ONCONFIG are environment variables.
hope this helps.

Also check if the variable ONCONFIG is set at all. If not IDS is using only the onconfig.std file, and the ROOTPATH in their will probably be empty.

Have you already found the solution??

Thanks ROOTPATH was wrong, I got it, but now we have another problem, the application server doesn't run because it doesn't find the database server. Where do I join the application with de database server?

java.sql.SQLException: com.informix.asf.IfxASFException: Attempt to connect to database server (ol_gandalf) failed.


Thank for all.

This is the sqlhosts file. This file should have an entry on the application server which point to the db server.

Hope this helps,
