Walden, I understand that teraspace can not be directly shared across multiple jobs, but that's really not much of an impediment to sharing teraspace. You just do it indirectly. If you create a job which allocates an instance of teraspace, and this job runs in batch as a daemon, it can provide shared access to common teraspace across all other jobs in your system. Other jobs can communicate with the Teraspace Server via two data queues. One to send requests to the server, the other to send result sets back to the client. A request to the server could contain a function code, a handle, and data. The result would be just handle and data. The handle/address cross reference could be stored in an array or based data structure in the server program, and the cookie/handle would be the array pointer or based data structure offset, depending on which way you went. Why wouldn't such a mechanism work ? -Dave K. ----- Original Message ----- From: "Walden H.
