HXRC device blocking and load balancing

The XP12000/XP10000 supports the IBM-compatible specifications for XRC device blocking and load

balancing control. In addition, the XP12000/XP10000 provides more flexible tuning methods for load

balancing control under HXRC environments as shown below.

Device blocking function

The XP12000/XP10000 HXRC function supports the new TSO command specifications for the XRC device

blocking function.

DONOTBLOCK option. DONOTBLOCK is a new option parameter that is specified by the XADDPAIR

command.
• DONOTBLOCK: The amount of write data for application programs are blocked by the threshold

specified by SDM. Default value is “500”HEX RECSETs.

• Specified: When the DONOTBLOCK option is specified to a logical device, the amount of write

data of application programs for the logical device is not blocked.

XQUERY. The number of RECSET and the current threshold value corresponding to a logical device will

be displayed by the XQUERY command.

CAUTION:

If you specify the DONOTBLOCK option for too many devices, a sidefile puncture condition

will occur. Use caution when determining the appropriate tuning (devices with DONOTBLOCK option, SVP

modes) for your operational environment.
