Autoinstall: Summary global statistics
Autoinstall summary global statistics are not available online.
| DFHSTUP name | Description |
|---|---|
| Autoinstall attempts | is the total number of eligible autoinstall attempts made during the entire CICS® session 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). |
| Rejected attempts | is the total number of eligible autoinstall attempts that were subsequently rejected during the entire CICS session. 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. |
| Deleted attempts | is the total number of deletions of terminal entries as users logged off during the entire session. |
| Peak concurrent attempts | is the highest number of attempts made during the entire CICS session to create terminal entries as users logged on at the same time. |
| Times the peak was reached | is the number of times that the “peak concurrent attempts” value was reached during the entire CICS session. |
| Times SETLOGON HOLD issued | is the number of times that the SETLOGON HOLD command was issued during the entire 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. |
| Queued logons | is the total number of attempts that were queued for logon due to delete in progress of the TCTTE for the previous session with the same LU. |
| Peak of queued logons | 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. |
| Times queued peak reached | is the number of times that the “peak of queued logons” value was reached. |
| Delete shipped interval | is the currently-specified time delay, in the form hhmmss, between invocations of the timeout delete transaction that removes redundant shipped terminal definitions. The value is set either by the DSHIPINT system initialization parameter, or by a subsequent SET DELETSHIPPED command. |
| Delete shipped idle time | is the currently-specified minimum time, in the form hhmmss, that an inactive shipped terminal definition must remain installed in this region, before it becomes eligible for removal by the CICS timeout delete transaction. The value is set either by the DSHIPIDL system initialization parameter, or by a subsequent SET DELETSHIPPED command. |
| Shipped terminals built | is the number of shipped remote terminal definitions installed at the start of the recording period, plus the number built during the recording period (which equates to the sum of “Shipped terminals installed”, a statistic not shown in the summary report, and “Shipped terminals timed out”). |
| Shipped terminals timed out | is the number of shipped remote terminal definitions deleted during the recording period by the TIMEOUT transaction. |
| Times interval expired | is the number of times the delete shipped interval
expired during the recording period.
|
| Remote deletes received | is the number of old-style (pre-CICS/ESA 4.1) remote delete instructions received by this region during the recording period. |
| Remote deletes issued | is the number of old-style (pre-CICS/ESA 4.1) remote delete instructions issued by this region during the recording period. |
| Successful remote deletes | is the number of shipped terminal definitions deleted from this region because of old-style remote delete instructions, during the recording period. |
| Total idle count | is the total number of times that all previously
used remote terminal definitions (whether deleted from the system
or currently in the system) had been idle awaiting reuse. This number does not include the remote terminal definitions currently idle awaiting reuse (see A04CIDCT). |
| Average idle time | is the average idle time (expressed in STCK units)
that all previously used remote terminal definitions (whether deleted
from the system or currently in the system) had been idle awaiting
reuse. This number does not include the remote terminal definitions currently idle awaiting reuse. |
| Maximum idle time | is the maximum time (expressed in STCK units)
for which a previously idle shipped terminal definition had been idle
during the recording period. This number does not include the remote terminal definitions currently idle awaiting reuse (A04CMAXI). |
