The following class 2 system parameters have been discontinued:

-CCPUNORM

-DELLOGLN

The following class 2 system parameters have been changed:

- JTABSMEM

Defines the maximum JIT memory on SX servers.

The memory is requested as resident and must therefore match the memory available on the machine.

As of BS2000/OSD V6.0A, the parameter default is 0 and JIT calcu- lates the maximum memory space from the two values for MEMORY-SIZE and MINIMAL-MEMORY-SIZE.

*1 The previous default value for JTABSMEM was 1200 MB.

The size of the requested memory is logged with the message HJT0039 on the console.

The memory size can also be set to a fixed value by specifying a value between 1 and 65535.

The parameter can be changed during operation.

- DMCMAXP

Defines the maximum number of entries in the MRSCAT of the home pubset.

The new maximum value is 4096.

- MEMORY parameter set

Discontinued parameter:

The parameter PAGING-GSSIZE is no longer available since the function "Using global storage for page changing" has been dis- continued.

New parameters:

The parameters BIG-PAGE-QUOTA and BIG-PAGE-SHRSIZE have been

*1 introduced for using so-called "big pages" for JIT compilations

*1 on SX150 business servers. A "big page" is taken to mean a collection of 512 consecutive 8 KB sized frames in main memory. BIG-PAGE-QUOTA defines the amount of main memory as a percentage that is to be reserved for the big pages.

The default value is 40%.

BIG-PAGE-SHRSIZE defines the size of the "shared big pages" that are used for the JIT compilation of shared programs. A range of from 0 to 64 MB can be specified.

The default value is 64.
