Server adapter data-containers are data containers associated with a DPL server adapter and MQSeries® server adapter, or both. They are used to store state and status data, inputs or outputs, or both input and outputs for server adapter program (server adapter activity).
DPL Server adapters use the EXEC CICS LINK command, that has a maximum COMMAREA length of 32,767 bytes. CICS® Service Flow Runtime supports 32,500 bytes. The remaining 267 bytes are taken up by the message header. See the CICS Application Program Reference for more information on the EXEC CICS LINK command.
Container Type | Contents and usage | Size (bytes) | Name |
---|---|---|---|
INPUT | Mapped input data. | variable max. 32,760 | COMMAND.INPUT |
OUTPUT | Output from the server adapters. | variable max. 32,760 | COMMAND.OUTPUT |
STATUS | Status information from server adapter, for example:
|
256 | COMMAND.STATUS |
