Autoinstall: Global statistics - Local definition

You can retrieve autoinstall global statistics by using the EXEC CICS COLLECT STATISTICS AUTOINSTALL system command. They are mapped by the DFHA04DS DSECT.

Table 1. Autoinstall: Global statistics - Local definition
DFHSTUP name Field name Description
Autoinstall attempts A04VADAT is the number of eligible autoinstall attempts made during the current session of CICS® to create terminal entries as users logged on. For an attempt to be considered eligible, CICS and z/OS® Communications Server must not be terminating, autoinstall must be enabled, and the terminal type must be valid for autoinstall (not pipeline, LU6.1, or LU6.2 parallel sessions).

Reset characteristic: reset to zero

 

Rejected attempts A04VADRJ is the number of eligible autoinstall attempts that were subsequently rejected during the current session of CICS. Reasons for rejection can be maximum concurrency value exceeded, invalid bind, the user program has rejected the logon, and so on. If this number is unduly high, check the reasons for rejection.

Reset characteristic: reset to zero

 

Deleted attempts A04VADLO is the number of deletions of terminal entries as users logged off during the current session.

Reset characteristic: reset to zero

 

Peak concurrent attempts A04VADPK is the highest number of attempts made during the current session to create terminal entries as users logged on at the same time.

Reset characteristic: reset to current value

 

Times the peak was reached A04VADPX is the number of times when the highest number of attempts were made during the current session to create terminal entries as users logged on at the same time.

Reset characteristic: reset to 1

 

Times SETLOGON HOLD issued A04VADSH is the number of times that the SETLOGON HOLD command was issued during this run of CICS. CICS issues the z/OS Communications Server SETLOGON HOLD command when the maximum number of concurrent autoinstall requests allowed (the AIQMAX= system initialization parameter) is exceeded.

Reset characteristic: reset to zero

 

Queued logons A04VADQT is the number of attempts that were queued for logon due to delete in progress of the TCTTE for the previous session with the same LU.

Reset characteristic: reset to zero

 

Peak of queued logons A04VADQK is the highest number of logons that were queued waiting for TCTTE deletion at any one time. If this is unduly high, consider increasing the delete delay interval parameter of the AILDELAY system initialization parameter.

Reset characteristic: reset to current value

 

Times queued peak reached A04VADQX is the number of times this peak was reached.

Reset characteristic: reset to 1
