ERDSASZE
The ERDSASZE system initialization parameter specifies the size of the ERDSA.
- ERDSASZE={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 1073741824
bytes in multiples of 1048576 bytes (1 MB). If the size specified
is not a multiple of 1 MB, 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 ERDSAZSE 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 31-bit storage (above the line) is specified by the EDSALIM system initialization parameter. You must allow at least 1 MB for each DSA in 31-bit storage for which you have not set a size.
