This article describes how MEMORY CACHE works in a local mode batch job.
Does the MEMORY CACHE option specified on a FILE in the DMCL get honoured in a local mode batch job?
CA-IDMS, all supported releases.
Yes. The MEMORY CACHE option is respected in a local mode batch job. But in local mode, IDMS always uses a 31-bit dataspace. In the CV, a file with MEMORY CACHE set will use a 64-bit storage if enough is available, otherwise it will use a 31-bit dataspace.
