Hello.

This question could be very fundamental, what is the concept of Database ON and OFF? how exactly these functions works in the system.

Hi,

Hopefully it's not only me, but you ball me out - IMS DB ON or OFF.. Does not convey anything to suggest, please explore a bit more.

Where did you hear/read this?

As Anuj mentions, you need to provide some clarification.

In our system, we do have jobs for each set of application IMS database ON (database UP)& and OFF (database down) jobs.

Normally at the beginning of job cycle OFF job will run at the end ON job will run.

Is this related to access mode to database? (Like read / alter).

Now we get it! I suggest that from now on, you refer to a database being UP - available online and to BMP processing or DOWN - stopped - only available to DLI jobs.

If you have a BMP environment, your databases will be UP most of the time except for a small window for backups and maintenance. If you do not have a BMP environment, your databases should be UP and available online during business hours. They are then taken off - or brought DOWN - for batch processing at night.

Is this what you needed to know?

Databases UP = started/ON-line
Databases Down = stopped/Off-line
