DFS0943I PSB PsbName REQUIRES A MINIMUM OF xxxxxxxx AND A MAXIMUM OF xxxxxxxx BYTES OF STORAGE IN THE EPCB POOL


or
PSB PsbName REQUIRES A MIN OF xxxxxxxx AND A MAX OF xxxxxxxx BYTES OF STORAGE IN EPCB POOL IF USING FAST PATH

Explanation

The message describes the amount of storage that the PSB requires in the EPCB pool.

The first form of this message is used only in IMS Version 10 and IMS Version 11.

You are attempting to size the EPCB pool. Each PCB with PROCOPT=H requires additional storage in the EPCB pool for use by High Speed Sequential Processing (HSSP). The information that is required to calculate the exact size of the additional storage needed by HSSP was unavailable at the creation of this message. There is a minimum and maximum amount of additional HSSP work area storage obtained for each HSSP-sensitive PCB. This additional HSSP work area storage is used to present the minimum and maximum amount of storage the PSB requires in the EPCB pool.

The MAXIMUM amount of storage the PSB requires in the EPCB pool includes each IOPCB and ALTPCB in the PSB.

System programmer response

Use the maximum required EPCB size, because the HSSP work area is not large enough to accommodate the required space for the PSB.
