CA-VIEW: EAS Locks a User's Session during Read of Tape


Article ID: 135030


Updated On:




The client's customers are not using the View EAS Tape Robotic (being able to present a report without loading it to the database disk layer), as the Selection (S) of a report on tape suspends a user's View session, whereas they cannot do any work until the report is presented. 

In a Load (L) from tape, the session is freed, where the user can continue doing other work, awaiting response that the report has been loaded. 

Is there a solution to this issue? 


Release : 14.0

Component : CA View


It was suggested that the client do the following, regarding their SAREAS task:

 . Consider setting a REGION=nnnM parameter, to provide sufficient storage for faster processing. 

 . In the SAREAS parameters, code NBUF to have a value greater than the value of (NTHREADS * NREAD). 

With use of a "L" (Load) command, View allows for the submitting of a background SARBCH job, that loads the report to the database disk layer.  

With using the Load, the user is notified (via their environment) that the SARBCH job has been completed, and the resulting report has been loaded to the disk layer and is available for viewing. 

Note: With use of the Load command, the SARINIT HOLDTEMP=nnn parameter is used, to determine how long the report temporarily stays on the disk layer. 

With a "S" (Select) command, if the report is on the disk layer, the report is presented instantaneously.  

Using "S" to select a report on tape, the current session is suspended until the tape is mounted and the report is located thereon, for presentation.  

The amount of time until the report is located and presented depends on several factors: 

 . What type of tape system is being used. 

 . What service class and REGION value are assigned to the SAREAS task. 

 . If there is a problem with the tape itself, that with a tape copy the Block IDs have been removed, and the tape needs to be read through report-by-report, until the report is located.
