Setting Resource Allocations
The RESOURCE command (abbreviated RE) sets system resource allocations. RESOURCE has
the following parameters:
RESOURCE (RE) [GRINS = global-rin-allocation ]
[RINS = total-rin-allocation ]
[IOMONT = io-monitor-table-size ]
[MAXCMCODE = cm code segment size ]
[CMSEGS = cm code segs per proc ]
[MAXXDATA = max size of xdata seg ]
[XDATAPERPROC = max data segs/proc ]
GRINS sets the number of global RINs to be allocated.
RINS sets the total number of global and local RINs to be allocated.
IOMONT sets the size of the I/O monitor area.
MAXCMCODE sets the maximum CM code segment size allowed for any given process.
MAXXDATA sets the maximum extra data segment size allowed.
XDATAPERPROC sets the maximum number of extra data segments for any given process.
NOTE Changes to GRINS and RINS take effect only if a tape containing the changes
is generated and the newly created tape is used to update the configuration or
install the system.
Table 7-2. shows the minimum and maximum values for the RESOURCE command
parameters.
