Re: Added 39.6GB file to backup, time only grew 4 minutes.

Hi Paul,

Thank you, I have already checked the TechDoc link posted by Rob, so
if the customer allows us to test it, I will switch it on.

Regards,
Bon

I should of posted all of these, to turn on ASYNCBRING within BRMS,

In V6R1 and above, override support for the new ASYNCBRING key on the QsrSave API to help improve IFS save performance is now possible using one of the following commands:
(Important Note: Enter the commands in uppercase only.)

To enable the new ASYNCBRING key:
CALL PGM(QBRM/Q1AOLD) PARM('PARMOVR' '*ADD' 'ASYNCBRING' '*YES')

To disable the new ASYNCBRING key:
CALL PGM(QBRM/Q1AOLD) PARM('PARMOVR' '*ADD' 'ASYNCBRING' '*NO ')

To remove the override, use the following command (default is *NO):
CALL PGM(QBRM/Q1AOLD) PARM('PARMOVR' '*REMOVE ' 'ASYNCBRING')

To show the current override being used, use the following command:
CALL PGM(QBRM/Q1AOLD) PARM('PARMOVR' '*DISPLAY' 'ASYNCBRING')

Rob,

Yes.

ASYNCBRING:.

I turned ASYNCBRING off, this is now what I see.
So according to the display you are currently off.

If you turn it on, should appear as below.

CALL PGM(QBRM/Q1AOLD) PARM('PARMOVR' '*DISPLAY' 'ASYNCBRING')
ASYNCBRING: *YES.

You mean like this snippet from my earlier email?

When you run this command do you see *YES or *NO

CALL PGM(QBRM/Q1AOLD) PARM('PARMOVR' '*DISPLAY' 'ASYNCBRING')
ASYNCBRING: *YES.

Comparing that with the BRMS flight recorder and it doesn't look like
we are using that.

Rob,

Are you using ASYNCBRING, default is *NO.
You may see even faster results.
My entire IFS save is only 5 minutes, LTO5 fiber.

Added a 39.6GB stream file to our backup. The save time only grew four
minutes. Yes, I am rather fond of fiber LTO4 drives.
