CICS server sessions definition

For each EXCI connection definition, you create a sessions definition.

The relevant parameters (shown in bold in the figures) are:
Connection
This sessions definition is associated with the JCOS connection.
Protocol
Specify EXCI.
RECEIVEPfx
This is a one or two character prefix for the receive session names. CICS® creates the remainder of the four character names from the alphanumeric characters A through Z, and 1 through 9. These two or three character identifiers begin with the letters AAA, and continue in ascending sequence until the number of session entries reaches the limit set by the RECEIVECount value (in our example JGAA, JGAB, JGAC, and so on). The default receive prefix is the < symbol.
RECEIVECount
This defines the number of sessions that can receive before sending. Because all EXCI sessions are receive sessions, this defines the number of pipes that can be used simultaneously. Because the EXCI imposes a maximum of LOGONLIM pipes for each EXCI address space, set RECEIVECount to a value larger than LOGONLIM.
SENDCount
Leave blank. Because EXCI sessions can only receive, there are no send sessions.
USERId
This defines the preset user identifier to be used for link security checking. It provides an additional security check for each transaction in addition to the flowed user ID. If you do not specify a preset user ID for link security, CICS uses the flowed user ID.
