CICSplex Link Analysis attribute group

The CICSplex Link Analysis attributes provide details on one or more links in a selected intersystem communication (ISC) or multiregion operation (MRO) connection. Use the CICSplex Link Analysis attributes to monitor the following conditions:

Condition and numbers of transactions and transmissions.
Link storage violations.

Note: These attributes are not available for situations. They provide data only for the Link Summary table view.

Count of Link Inputs Indicates the number of input requests on this link. The value format is a positive integer, a maximum of four bytes.

Count of Link Outputs Indicates the number of output requests on this link. The value format is a positive integer, a maximum of four bytes.

Count of Link Storage Violations Indicates the number of storage violations associated with this link. The value format is a positive integer, a maximum of four bytes.

Count of Link Transaction Errors Indicates the number of transaction errors on this link. The value format is a positive integer, a maximum of two bytes.

Count of Link Transactions Indicates the number of transactions run on this link. The value format is a positive integer, a maximum of four bytes.

Count of Link Transmission Errors Indicates the number transmission errors on this link. The value format is a positive integer, a maximum of two bytes.

Current Transaction Number Indicates the number of the transaction currently executing on this link. The value format is an alphanumeric string, a maximum of five characters.

Link Connection Name Indicates the name of the connection that owns this link session. The value format is an alphanumeric string, a maximum of four characters.

Link Current Tranid Indicates the name of the currently executing transaction. The value format is an alphanumeric string, a maximum of four characters.

Link Netname Indicates the name of the VTAM applid to which this link is or will be connected. The value format is an alphanumeric string, a maximum of eight characters.

Link Next Tranid Indicates the name of the next scheduled transaction on this link. The value format is an alphanumeric string, a maximum of four characters.

Link Region 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, and case-sensitive. CICS region names are always in uppercase characters.

Link Session Status Indicates the status of the link. These are the valid values for ISC connections:

INS: In service
OUT: Out of service

For MRO connections, the valid values are:

REL_OUT: Released, out of service
REL_INS: Released, in service
SIMLOGON: CICS issues a VTAM logon request to start a session with a device, and the request has not completed
ACQ_OUT: Acquired, out of service
OBT_INS: Connection is being obtained
FRE_INS: Connection is being freed
AVA_INS: Acquired, no sessions bound
PENDING: The named connection is not yet available. The remote scheduler has not yet completed processing

Link System ID Indicates the SMF identifier that uniquely identifies an active z/OS operating system. The valid format is an alphanumeric string, with a maximum of four characters.

Link Termid Indicates the name, from the TCTTE, of this link. The value format is an alphanumeric string, a maximum of four characters.

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

When a situation is true, the system 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, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.

Resource Name The name of the resource the transaction is waiting to access. This name is an alphanumeric string, with a maximum of eight characters.

Resource Type The category of resource the transaction is waiting to access. This name is an alphanumeric string, with a maximum of eight characters.
