Re: Lock mode

In Response To: Lock mode (Georges Martin)

I don't quite understand your question... Usually a program establishes just
one connection to the database...
Once you SET LOCK MODE TO... in a session it will keep it for the duration
of the session (until another SET LOCK MODE... instruction is sent).
As others said, IDS 11.10+ has a functionality which you can use to redefine
the LOCK MODE (an other options) without changing the application code.
That functionality is the special sysdbopen() procedure which can be seen as
a sort of .profile of a session. Note that this was introduced in IDS 11.10,
not v10.
Finally, if your application uses JDBC the driver supports a property to
automatically define the LOCK MODE. Unfortunately this is not supported for
other types of connections (ODBC/.NET/OLEDB would be nice...)
If this is not enough, please give us more information.
Regards.
