In Response To: Re: IDS 940 64-Bit / 32-Bit conversion question (Art Kagel)

Thank you Art, thank you David too for yours answers.
I came back with a new questions on the same subject.

It is not a 'downgrade to 32bit' : I need for 32bit for short time and
after I will finish I want to come back on 64bit.
In fact I need to restore a database from production into a test server.
In production server I have an IDS 940 UC2.
On the test server I have an IDS 940 FC7 (with SOLARIS 10). Due to a
lack of machines I have to restore the server backup in 32bit format
over a server in 64bit. For the 32bit version I have not disk space to
make its own server configuration . I want to use the same disk spaces
as were used for 64bit server.

Now I have installed the IDS 940 UC2 into a different directory than
it was used for IDS 940 FC7.
I have configured the new environment (INFORMIXDIR, ONCONFIG, SQLHOSTS)
for 32bit
and I'm able to start the 32bit server. My server in 32bit it is ONLINE
but_ I think that the conversion does not complete._
In the online.log file I did not found any conversion errors , even the
message like 'Conversion completed successfully' it is not present there.
I performed the oncheck commands as are detailed into the doc (Migrating
to Dynamic Server 9.40 or 9.30 from 9.x, 7.3x, or 7.24) and no errors
were reported there.
When I try to make the L0 backup of the 32bit server it does not work:
- if the server it is ONLINE and I start the "ontape -s -L 0" - the
server crashes and I receive the error:
/"Archive failed - buc_fe.c : Archive API processing failed at line 236
for msgtype"

/- if the server it is OFFLINE and I start the "ontape -s -L 0" - the
backup stops and I receive the error:
/"Server is in an incompatible state or user authentication failed."

/Please let me know what I did wrong.

For me now this backup L0 it is not important because I do not need for
it. I need to restore over it a different backup in 32bit format.
Later, when I will finish with it I want to restore over it the backup
of 64bit server ( I made it before stating the server conversion) and I
want to start the
64bit server. It will work?

Thank you for your help,
Elena
