In Response To: onstat -g dis gives bad info (MICHAEL HOFFMAN)

original post:

Hi All,
Where does 'onstat -g dis' gather its information from?
We have a server that is reporting an instance that should never have existed on that server.

Server : legacy_tcp
Server Number : 9
Server Type : IDS
Server Status : Down
Server Version: IBM Informix Dynamic Server Version 12.10.FC4
Shared Memory : 0xa000000
INFORMIXDIR : /soft/prodinformix/foghorn
ONCONFIG : /soft/prodinformix/foghorn/etc/onconfig.legacy
SQLHOSTS : /soft/prodinformix/foghorn/etc/sqlhosts.legacy
Host : devdata2

Neither ONCONFIG nor SQLHOSTS file exists. Nor does the instance.

I looked at /INFORMIXTMP/.infdirs -- several directories listed, but there is no reference to legacy_tcp in any of the etc/sqlhost* or etc/onconf* files under any of the listed informix directories.

This leads me to believe that the info is stored somewhere else-- but since the command can be run off-line, it can't be in sysmaster.

I really want to clean up these servers before we upgrade.
Any help would be appreciated.

Thanks,
Michael Hoffman

Response:

I believe onstat -g dis uses the /INFORMIXTMP/.infdirs to get a list of directories to check. It then looks for files named ".conf.<something>" in the etc directory Note the "." That file is not a plain text file. I believe it's getting all that information from those .conf files it finds in all the informix dirs listed in the .infdirs file. One way you can verify this would be to use strace or truss and send the output to a file for the onstat -g dis command...so run something like this:

strace -o trace.out onstat -g dis

In that trace.out file you would see opens for the $INFORMIXDIR/etc/.conf.#### files.

I'm trying to recall this off the top of my head so I might be a tad off, but I'm pretty sure that's what it is doing and where it's getting it's info from.
