Shared Program Command SP
Purpose: | Specifies the number of shared programs and the number of extended schedule | |
| table programs in the system. These numbers indicate the number of different | |
| programs, not the total number of copies. Note that extended schedule table | |
| programs do not need to be shared programs, although it is permitted. | |
Syntax: | SP,n[,m] | |
| n | is the number of shared programs. |
| m | is the number of extended schedule table programs. |
System Memory Block Command MB
Purpose: | Specifies the size of the system memory block. |
Syntax: MB,n
nis the number of words reserved for the system memory block.
Description:
The system memory block is used by the networking products, DS/1000IV and NSARPA/1000. Refer to the DS/1000IV or NSARPA/1000 manual set for more information.
Concurrent User Command US
Purpose: | Specifies the number of concurrent users in the system. |
Syntax: US,n
nis the number of concurrent users allowed at one time in the system.
LOGOF Buffer Limit Command LB
Purpose: | Specifies the number of LOGOF information buffers that may occupy SAM | |
| concurrently. | |
Syntax: | LB[,n] | |
| n | is the number of buffers. Default is 25% of number of concurrent users. |
Description:
When a user logs off, a session information buffer is created by RTE which the LOGON program reads. If many users log off at once, the LOGON program may not run quickly enough to deallocate all the information buffers, causing SAM to become fragmented or clogged. You specify the number of information buffers that may occupy SAM; if the buffer limit has been reached and another user logs off, no session information is saved.
