Vary SCRatch

Specifies the size of the secondary allocation, maximum amount of storage, and storage location.

LOCation

Specifies where memory for the scratch information is allocated with the following options:

ANY|XA|64-bit

Determines the storage location. The storage needed for scratch processing is allocated directly from the operating system and not from the CA IDMS storage pools.

ANY Acquires 64-bit storage if possible. If the request to allocate 64-bit storage fails, XA storage is acquired.

XA Acquires 31-bit storage.

64-bit Acquires 64-bit storage. If the request to allocate 64-bit storage fails, no attempt to acquire XA storage is done.

SECondary extent is

Specifies the secondary scratch allocation size.

sec-size-with-unit

Specifies the amount of additional storage acquired when all existing scratch storage is in use. Enter a number in the range 1-32767 followed by a unit of KB (Kilobyte: 2**10), MB (Megabyte: 2**20), GB (Gigabyte: 2**30), TB (Terabyte: 2**40), or PB (Petabyte: 2**50).

LIMit is

Specifies the maximum scratch allocation size.

limit-with-unit

Specifies the maximum amount of scratch storage. The system continues to allocate more storage for scratch processing until the sum of all allocations reaches the value specified by limit-with-unit. Enter a number in the range 1-32767 followed by a unit of KB (Kilobyte: 2**10), MB (Megabyte: 2**20), GB (Gigabyte: 2**30), TB (Terabyte: 2**40), or PB (Petabyte: 2**50).
