BMP Mode Parameters panel

The BMP Mode Parameters panel allows you to view and modify the parameters that are passed to the IMS region controller when a File Manager/IMS function is run in BMP mode.

The panel is displayed when option 5 is selected on the Subsystem Settings Menu.

The panel displays the parameters that an online FM/IMS function uses when a BMP region type is selected and this IMS subsystem ID is specified on the function's Entry panel. The Subsystem field displays the IMS subsystem ID you specified on the Subsystem Settings Menu.

The FM/IMS administrator may have fixed the values of some or all of the parameters displayed on the panel.

If a parameter has been fixed, the panel field will be protected and you will not be able to change the specified value. If a parameter has not been fixed, you can change the value that has been specified for it.

Enter the RESET command to reset all the parameters on the panel to their subsystem defaults.

Enter the EXIT command (F3) to exit the panel saving the changes you have made.

Enter the CANCEL command (F12) to exit the panel without saving the changes you have made.

Subsystem
The IMS subsystem ID you specified on the Subsystem Settings Menu.
PARDLI
Specify the parallel DL/I option used by functions running in BMP mode:
1 - PARDLI=0
DL/I processing is performed in the BMP region.
2 - PARDLI=1
All DL/I processing for the BMP is performed in the IMS control region.

PARDLI=1 prevents control region system 113 abends resulting from system X22 abends in the BMP region. However, if PARDLI=1, parallel DL/I is disabled. This can degrade performance.

Normal Buffer Allocation (NBA)
The number of Fast Path database buffers to be made available in the Common Service Area when a Fast Path region is activated. The number specified is used by functions when they access Fast Path databases.

Must be in the range 1 to 9999.

Overflow Buffer Allocation (OBA)
The number of additional page-fixed buffers to be made available to a Fast Path region if the normal allotment (specified in the NBA field) is used. The number specified is used by functions when they access Fast Path databases.

Must be in the range 1 to 9999.

LOCKMAX
The maximum number of locks (in units of 1000) that a function is allowed to hold at one time. The number must be in the range 0 to 32767.

If 0 is specified, there is no limit on the number of locks the function can hold at one time.

If you leave the field blank, the LOCKMAX value specified on the PSBGEN statement is used or 0 (no limit), if the LOCKMAX parameter is not specified on the PSBGEN statement.
