The RDSASZE system initialization
parameter specifies the size of the RDSA.
- RDSASZE={0K|number}
- The default size is 0, indicating that the DSA size can change
dynamically. A non-zero value indicates that the DSA size is fixed.
- number
- specify number as an amount of storage in the range 0 to 16777215
bytes in multiples of 262144 bytes (256 KB). If the size specified
is not a multiple of 256 KB, CICS rounds the value up to the next
multiple.
You can specify number in bytes (for example, 4194304),
or as a whole number of kilobytes (for example, 4096 KB), or a whole
number of megabytes (for example, 4 MB).
Restrictions You can specify the RDSAZSE
parameter in PARM, SYSIN, or CONSOLE only.
CAUTION:
Setting the size of individual dynamic storage areas
(DSAs) is not usually necessary and is not recommended. If you specify
DSA size values that in combination do not allow sufficient space
for the remaining DSAs, CICS fails to initialize. The limit on the
storage available for the DSAs in 24-bit storage (below the line)
is specified by the DSALIM system initialization parameter. You must
allow at least 256K for each DSA in 24-bit storage for which you have
not set a size.
