If you have any idia please suggest me for the solution. The 'problem' is there in earlier releases - you just got lucky. Basically you cannot do this. Before making such copies you have to quiesce the database and sync to disk. There is a command in your version of jBASE that might help though: Try a script: #! /bin/ksh DB-PAUSE sync # command to do filesystem copy goes here DB-RESUME However, I am unfamiliar with the use of those commands (I don't think it is a good way to do things) so check with TEMENOS or others here that may have done this. Even with the above, while it should mean you don't get a corrupt file, it does nothing to protect against the fact that you might be half way through a transaction, so the target copy is still next to useless. You need to implement transaction journaling and jlogdup. Jim   On Sun, Aug 2, 2009 at 10:47 PM, Jim Idle <j...@temporal-wave.com> wrote: kumar wrote: > Hi, I am using jbase5.0.6 and T24 R07.
