Assignee:

Unisys Corporation - Blue Bell PA

International Classification:

G06F003/00

US Classification:

719310

Abstract:

A method for providing a program which executes a sequence for handling a suspended task. The method includes the steps of performing a security check on a mainframe server. The program then detects a response from the suspended task, and then monitors and handles the response. Finally, the program re-activates the suspended task with the response.

Appl. No.:

13/298410

Inventors:

Donald Hart - Foothill Ranch CA, US
Kung Lin - Irvine CA, US

International Classification:

G06F 17/30

US Classification:

707803, 707E17005

Abstract:

Methods and systems are disclosed to perform record counts of particular structures without causing database-wide locking to occur while such counting is being performed. A Data Definition Language (“DDL”) syntax referred to as RECORDCOUNT is specified at the structure level to enable a particular structure to be locked for performance of record count operations without locking the global dataset record. Updates or deletions/insertions to other structures can still be made by locking the structures associated with the RECORDCOUNT operation and not the global dataset. Further, the RECORDCOUNT option can be added to existing structures to enable structure-specific locking for performance of record counts.
