The CICSplex Connections Summary attributes 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 (the maximum number of requests that originate in this region than can be queued).
Allocation Percentage Is the percentage of link allocations across connections of this type.
Allocation Rate Is the rate per minute at which 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 operating system has a unique name. This name is an alphanumeric string, with a maximum of eight characters. CICS region names are always in uppercase characters.
CICS Region VTAM Applid Is the eight character name that specifies the generic VTAM Applid of the CICS region.
CICS Region VTAM Generic Applid Is the eight 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 by which 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. One of ISC, MRO, and IPIC.
Maximum Receive Sessions in Use Is the peak number of receive sessions in use on this connection at any one time since CICS started or since statistics were last reset.
Maximum Send Sessions in Use Is the peak number of send sessions in use on this connection at any one time since CICS started or since statistics were last reset.
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 is the percent of maximum receive sessions in use based on the negotiated receive sessions.
Percent of Maximum Send Sessions in Use Is the percent of maximum send sessions in use based on the negotiated receive sessions.
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. 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 Indicates how many sessions of this type have been received.
Total Send Sessions in Use Indicates how many sessions of this type have been sent.
