Hi,

Once we write all JCL statements into IRDR TDQ, at what point job will get triggered/submitted from TDQ?

Please help me.

The answer to your question depends on the system setup:

How many records per block for IRDR TDQ? If the block size is greater than 1 record per block, the job won't be submitted until the block fills up and the buffer is flushed.

How frequently do jobs get submitted? A JOB card will cause any existing job in the buffer to be submitted to JES.

If you're wanting quick submission, use /*EOF (from the JCL User's Guide):
Quote:
Sending Internal Reader Buffer Directly to JES

Instead of waiting for the buffer in your address space to fill up, send the contents of the internal reader buffer directly to JES by coding as the last record in the job:

/*EOF
This control statement delimits the job in the data set and makes it eligible for immediate processing.

Thanks, icon_smile.gif

I could see the statement /*EOF in my JCL as last statment.

Once writing JCL statements to TDQ got over, would see the following statemet in my program.

EXEC CICS
SEND CONTROL
FREEKB
END-EXEC.

What does above statement will do along with TDQ?

EXEC CICS
SEND CONTROL
FREEKB
END-EXEC.


this is sending a control response to 3270 terminal to free
the keyboard. Why not just look in CICS applications programmer
guide when you have questions about EXEC CICS commands?

For submitting JCL from CICS, you could also use the
EXEC CICS SPOOL commands, use the internet or look in CICS
manuals for additional information..
