ISC/IRC attach time entry statistics

The ISC/IRC attach time statistics of the DFHSTUP listing is for a CICS® system using intersystem communication or interregion communication. It provides summary statistics for the number of times that the entries on the Persistent Verification 'signed on from' list are either reused or timed out. Using this data you can adjust the USRDELAY, and the PVDELAY system initialization parameters.

This section contains the following statistics:

ISC/IRC attach time: Resource statistics

These statistics are collected if you have either an LU6.2 connection or IRC defined in your CICS region, and they are then produced globally, one per system. These statistics cannot be accessed online using the EXEC CICS COLLECT STATISTICS command; they are only produced for offline processing (written to SMF).

These statistics are mapped by the DFHA21DS DSECT.

Table 74. ISC/IRC attach time: Resource statistics
DFHSTUP name Field name Description
Persistent Verification refresh time A21_SIT_LUIT_TIME is the time in minutes set by the PVDELAY system initialization parameter. It specifies the password re-verification interval. The range is from zero through 10080 minutes (seven days) and the default is 30 minutes. If a value of zero is specified, entries are deleted immediately after use.

Reset characteristic: not reset

 

ISC Persistent Verification Activity: Entries reused A21_LUIT_TOTAL_REUSES refers to the number of entries in the PV 'signed on from' list of a remote system that were reused without reference to an external security manager (ESM), such as RACF®.

Reset characteristic: reset to zero

 

ISC Persistent Verification Activity: Entries timed out A21_LUIT_TOTAL_TIMEOUT refers to the number of entries in the PV 'signed on from' list of a remote system that were timed out.

Reset characteristic: reset to zero

 

ISC Verification Activity: Average reuse time between entries A21_LUIT_AV_REUSE_TIME refers to the average time that has elapsed between each reuse of an entry in the PV 'signed on from' list of a remote system.

Reset characteristic: reset to zero

 

ISC/IRC attach time: Summary resource statistics

Summary statistics are not available online.

These statistics are collected only if you have either an LU6.2 connection or IRC defined in your CICS region, and they are then produced globally, one per system.

Table 75. ISC/IRC attach time: Summary resource statistics
DFHSTUP name Description
Persistent verification refresh time is the time in minutes set by the PVDELAY parameter of the SIT. It specifies how long entries are allowed to remain unused in the PV 'signed on from' list of a remote system.

 

Entries reused refers to the number of times that user’s entries in the PV 'signed on from' list were reused without referencing the ESM of the remote system.

 

Entries timed out refers to the number of user’s entries in the PV 'signed on from' list that were timed out after a period of inactivity.

 

Average reuse time between entries refers to the average amount of time that has elapsed between each reuse of a user’s entry in the PV 'signed on from' list.
