Re: Need To Journal Files & System Impact

Hi

Like Rob I don;t usually worry about setting up an additional ASP for
journalling, but I do try very hard to get the journals and receivers put
into separate distinct libraries, not just dumped into the application
library.

If ar all possible create a library called something like @@JRN to hold the
journals and @@JRCV to hold the receivers.

The reason for this is to ensure that the receivers and journals are
restored before the supported objects when you are doing a recovery and
journalling is automatically resumed on all object being restored.

I have a small group of files that I need to start to journal. Is there

a

way to determine how journaling of these files would impact a system.
Example: How big the journal receiver will get, how many entries, CPU
overhead, should the objects be in the same library, etc. Was not sure

if

there is a way to determine this or not.
