Issue/Introduction

APAR LT06425 introduced two new PARMS. How are these used and are these included in the ICOM STC PROCs in the PARM statement  or in the CA7 INIT deck?

Environment

Release : 12.1

Component :

Resolution

 

The CA7ICOM JCL procedure may be modified to include the following parameters to activate U7SVC dataset creation monitoring.  When U7SVC Dataset Creation Monitoring is in effect, all dataset creations by the U7SVC facility are monitored for frequency within a specified interval. 

 

DCOI=nnnnnn

Length in milliseconds of a U7SVC dataset creation monitoring interval  

Valid values: 1-999999

1000 = 1 second

 

DCRC=999999

The maximum number of U7SVC dataset creations for a unique dataset name by a unique task name within the monitoring interval (DCOI) before a dataset / task combination is considered critical. 

Valid values: 1-999999

 

When a dataset / task combination becomes critical, the following WTO is issued:

CAL2108I DSN dddddddddddddddddddddddddddddddddddddddddddd Task tttttttt critical 

 

When the subsequent number of creations observed for a critical dataset / task does not exceed the DCRC limit for approximately 5 consecutive intervals, the following WTO is issued:

CAL2109I DSN dddddddddddddddddddddddddddddddddddddddddddd Task tttttttt no longer critical 

 

 

Messages 

CAL2108I DSN dddddddddddddddddddddddddddddddddddddddddddd Task tttttttt critical 

The dataset name was created using the U7SVC facility by the task name more than the number of times specified by the ICOM DCRC parameter within the interval specified by the DCOI parameter. 

Action:

None required - information only.  

 

CAL2109I DSN dddddddddddddddddddddddddddddddddddddddddddd Task tttttttt no longer critical 

The number of U7SVC creations of a critical status dataset name / task combination was not over the limit specified by the ICOM  DCRC parameter for 5 consecutive intervals (DCOI). 

Action:

None required - information only.  

 

CAL2110I Dataset Monitoring Deactivated 

U7SVC Dataset monitoring was requested in the ICOM facility but a virtual storage error prevented the monitor from initializing.

Action:

Increase the region size and restart ICOM 

 

CAL2111I Dataset Monitoring Data Lost

U7SVC Dataset monitoring failed to obtain additional virtual storage needed to monitor all dataset creations that are concurrently active. Some dataset name / task combinations will not be monitored at various times during this execution of ICOM.

Action:

Increase the region size and restart ICOM
