For a single connector processing pattern, server adapter data containers are containers associated with a DPL server adapter only. They are used to store state and status data, inputs or outputs, or both input and outputs for the DPL 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.
The following table lists the DPL server adapter data containers used at run time.
Container Type | Contents and usage | Size (bytes) | Name |
---|---|---|---|
OUTPUT | Application data that will be sent in the adapter reply message. Navigation Manager writes a copy of server adapter activity output container for purposes of returning adapter reply message. |
variable max. 32,500 | ADAPTER.OUTPUT |
STATUS | Status information from DPL server adapter, for
example
|
256 | COMMAND.STATUS |
