Wally, are you the DBA that setup this instance? If not, you should be
working with that person to determine what is going on with the
instance.

If you are, then we need to know what you have done to this point
towards building, running, and securing the instance for usage and
recovery.

Thanks,

No, you need ontape -s -L 0 something similar to this.

I found one logical log backup using "ontape -a" in production server.

"Starting ontape -a Sat Sep 5 03:00:00 PDT 2009

Performing automatic backup of logical logs.

Please mount tape 1 on /backups/informix_lg and press Return to continue
.....

Do you want to back up the current logical log? (y/n) Please label this
tape
as number 1 in the log tape sequence.

This tape contains the following logical logs:

588 - 596

Program over.
Ontape -a complete Sat Sep 5 03:00:28 PDT 2009 Done..."

Is this my level 0 backup?

Thanks.

You must look for some evidence, such as "building sysmaster
database"... If you found that phrase, brow... you're in a bad
situation and prove that somebody created a new instance overwriting
your old instance.

To fix that, only restoring your databases performing a level 0
backup, as I mentioned before.

Look you online.log as I mentioned, and let me know...

I don't think that anyone would run the oninit -i. How do I find out
that
one did that?

Did you perform by accicdent oninit -i??? If you did that, you
initialized a new instance (without database application). To restore
you application database, you must perform a restore from your last
level 0 backup.

Otherwise, somebody who has sufficient privileges dropped your database
application... and to recover, you also must perform a restore from your

last level 0 backup.

You can look your online.log and find for a message, such as "Database
(database_name) dropped".

I hope that you have a valid level 0 backup...

Good Luck,

Thanks, Alberto. I got to the line "Verbose output complete mode=5", but

I
only have the sysmaster@onlinedev and sysutils@onlinedev. I should see
six
other databases, how can I bring back the missing databases.

Thanks.

To up your informix server database, execute oninit -v command using
Informix user.

If everything r working properly, the last line must be:

Verbose output complete mode=5

If not, you must look the Informix message file. Execute onstat -m to
view your online log.

Subject: shared memory not initialized for INFORMIXSERVER

Hi,

On our development server (IDS 7.31.UD6 on HPUX B.11.11), when we
executed
dbaccess dbname, we got error message "25588: The appl process connot
connect to Dynamic server". When I onstat -d, I got "shared memory no
initialized for INFORMIXSERVER 'onlinedev'".

What should I do?

Thanks in advance.
