ORA 12162 / 12170 and Oracle 10G

Hello

Still with Itanium OpenVMS 8.3-1H1 and oracle 10G R2

After installing Oracle 10 G R2 and created a test database, I have started and shut Oracle several times with
$ sqlplus / as sysdba
shutdown
or startup

and
beqlsnr stop

Then I have modified the file in [network.admin]
tnsnames.ora in order to add my database TEST
on a remote PC and the Vms server.
I then connected fine from the PC on my TEST database.

A little later, any attempt to log in fails with ORA-12162

I noticed ora_sid was no longer defined, so I defined it again, and now

$ SQLPLUS "/ AS SYSDBA"

SQL*Plus: Release 10.2.0.2.0 - Production on Thu Mar 26 17:37:37 2009

Copyright (c) 1982, 2005, Oracle. All Rights Reserved.

ERROR:
ORA-12170: TNS:Connect timeout occurred


Enter user-name:


I have looked at metalink
VMS: Checklist for TNS-12170 errors when accessing or creating a database
Doc ID: 434836.1

but found nothing

I have renamed the file tnsnames.ora
I have the logical ora_sid in the logical table.

Thanks for any hint

When you modified it, did you take care to assure that the file retained the stream_lf attribute?
Most (just make it all) Oracle control files now HAVE to be stream_lf.

If they are not, then to fix it on 8.3 you can use one-liners like:

$conve/fdl="record; format stream_lf" tns_admin:SQLNET.ORA tns_admin:/stat

And a litte script that might be belpful below.

Hope this helps,
Hein.

Thanks Hein

It works now, and while I had applied the doc when creating the tnsnames.ora, I had not checked after my modif, so I guess this is the reason of the problem.

I do not understand why I still had this error after renaming the file ?
There is a faulty logic here I think, as with Oracle 10, stop or start Oracle means using
sqlplus.
And this command is unavailable then...

Getting tired, I rebooted and it works fine now.
