CICSplex Connections Summary attribute group

The CICSplex Connections Summary table view helps you analyze the efficiency of multiregion operation (MRO), intersystem communication (ISC) and IP interconnectivity connections (IPCONN) links and detect capacity constraints that could cause bottlenecks.

Allocation Count Is the total count of allocate requests for this type of connection.

Allocation Percentage Is the percentage of link allocations across connections of this type.

Allocation Rate Is the rate per minute that the link allocations are occurring across connections of this type.

CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS image has a unique name. This name is an alphanumeric string, with a maximum of 8 characters, and case-sensitive. CICS region names are always in uppercase characters.

CICS Region VTAM Applid Is the 8 character name that specifies the generic VTAM applid of the CICS region.

CICS Region VTAM Generic Applid Is the 8 character name that specifies the VTAM applid of the CICS region.

CICS systems that use XRF have two applid names: a generic name and a specific name. The names are specified on the APPLID(=generic-applid,specific-applid) system initialization parameter. The active and alternate CICS systems must have the same generic applid and different specific applids. For XRF, a CICS system's generic applid is defined on the APPLID system initialization parameter and is the name that CICS is known in the network. It is the name quoted by remote CICS systems, on the NETNAME option of CONNECTION definitions or the APPLID option of IPCONN definitions, to identify this CICS. A CICS system's specific applid is used to distinguish between the pair of XRF systems. It is the name quoted on a VTAM APPL statement, to identify this CICS to VTAM.

Connection Type Is the type of connection between the selected region and this region.

Maximum Receive Sessions in Use Is the peak number of receive sessions in use on this connection.

Maximum Send Sessions in Use Is the peak number of send sessions in use on this connection.

Origin Node Is the combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.

When a situation is true, Tivoli Enterprise Portal compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, Tivoli Enterprise Portal changes the status of the item accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.

Percent of Maximum Receive Sessions in Use Is the maximum number of receive sessions in use on this connection at any one time since CICS started or since statistics were last reset.

Percent of Maximum Send Sessions in Use Is the percent of maximum send sessions in use based on the negotiated send limit.

System ID Indicates the 4 character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum 4 characters, and case-sensitive. z/OS System IDs are always in uppercase characters.

Total Number of Connections Is the total number of connections of the type indicated under 'Connection Type'.

Total Receive Sessions in Use Shows the number of receive sessions currently in use.

Total Send Sessions in Use Shows how many send sessions are currently in use.
