Capacity requirements - USS

The following are general guidelines regarding the real frames and aux storage slot usage of the CAE address spaces.

A CAE agent must be active on each z/OS® image that you want to see in a CAE browser client.

Real Frames

To prevent excessive paging, the CAE agent address space requires a minimum of 1,000 real frames.

Aux Storage

Typically, the CAE agent address space does not hold on to large amounts of memory. During requests for large numbers of rows the CAE agent requires brief, temporary use of less than 3K bytes for each row. The default region size of 70M allows users to retrieve about 20,000 rows, limited then by the capacity of the CAE server address space.

The CAE server can run on a Windows® workstation where it does not use z/OS resources.

Real Frames

To prevent excessive paging, the CAE server under USS requires a minimum of 20T real frames.

Aux Storage

Typically, the CAE server under USS uses 30T to 50T aux storage slots. With heavy use, it can require up to 90T aux storage slots. You should allow that existing-aux-storage-usage + 90T < 30% of total aux storage.
