Hi,

We are currently running Continuus 5.0 on Wnidows Nt 4. We plan to migration the database to a Solaris 8 server running the same version of Continuus. So I did the installation on the Unix server and create en empty database: everything seems ok. Now I've tried to migration a database and I got an error. Here's what I did:

On the Windows NT 4 server. I packed a database (ccmdb pack ...)
I tranfert this file to the Solaris 8. Then try to unpack it and I have the following error message:

bash-2.03$ ccmdb unpack test.cpk -t /var/opt/ccm/ccmdb/test24
UnPacking Database /var/opt/ccm/ccmdb/test24 from /var/opt/ccm/test.cpk
extracting .cpk file...
loading database...
Loading database /var/opt/ccm/ccmdb/test24/db from standard in.
...tform WINDOWS_NTmp file version 5.0
loading table attrib...
ERROR: Illegal data in input stream, aborting
Database load failed.
database load failed.
ERROR: Database is not inactive, can't continue.


Can someone help me out?

Thanks alot!

Firstly I think you need the -w option in the Unix unpack command for starters (if it's available under 5.0 - I can't remember that far back). However that may only be the start of your problems. We first tried such a move under Synergy 6.1 and it was horrendous; it got better under 6.2 and now we're on 6.3 we may try some more databases because again Windows to Unix conversion is supposed to be improved.

Good luck!

Thanks alot Russ.

I've been able to unpack a small database but I had another problem with a bigger one.

The pack file is about 2.7 gigs and I have the llowing error message:

bash-2.03$ ccmdb unpack ppfi.cpk -w -t /var/opt/ccm/ccmdb/ppfi
UnPacking Database /var/opt/ccm/ccmdb/ppfi from /var/opt/ccm/ppfi.cpk
extracting .cpk file...
cat: cannot open /var/opt/ccm/ppfi.cpk

ccm_gzip: stdin: unexpected end of file
loading database...
cat: cannot open ./DBdump.Z

ccm_gzip: stdin: unexpected end of file
Loading database /var/opt/ccm/ccmdb/ppfi/db from standard in.
ERROR: Database dump file is missing the required version field.
Database load failed.
database load failed.
ERROR: Database is not inactive, can't continue.
llowing error message:

Is there any limitation in the ccm_gzip on Solaris?

Thanks!

My Unix knowledge is paper-thin is but that looks very much like a space problem - did you create a big enough chunk (or chunks) in your dbspace? ccmsrv status -d -s <server> may help there.

Not sure if this helps either but I've dug up our old NT-Unix conversion notes. A very strong recommendation is to ensure that the database has all objects made static (ie checked in) & a clean_cache with zero lead time is run before packing. Once successfully(!) unpacked on Unix, a procedure must be run to convert any ascii cache files from dos to unix format.

Thanks a lot Russ...

The last error message was my mistake... I forgot to give the rights to ccm_root on the pack file

Also, thanks for the information about clean cache and the conversion of ascii cache file... I'll check that later if I can just unpack a database.

Thanks again!
