If you cannot set SORTSPACE to allocate enough contiguous memory for a SORT operation, set SORTTEMPSPACE to the required amount, and then set SORTSPACE to a smaller value. Memory is then allocated in chunks of the size specified by SORTSPACE, until it has allocated the value set by SORTTEMPSPACE.
We recommend that you use SORTTEMPSPACE only if you are receiving COBRT105 Memory allocation error (Fatal) errors.
Specify the amount of memory in one of the following formats:
The maximum value is 4,294,967,295 bytes (4GB - 1 byte).
