Utility Locking

Some utilities require exclusive use of certain MDM-RE system resources. These include the:

Table Loader

Update Synchronizer

Refresh / Delete utility

When the utility starts it will acquire application level locks within the Rulebase for the appropriate resources. Other processes that require the same locks will not be allowed to run.

For example, locks are used to prevent two Update Synchronizers from updating the same IDT and IDXs concurrently.

The

lockmgr

utility (documented in the Batch Utilities
chapter) is used to list and delete locks in the situation when a utility terminates abnormally while holding locks. In most situations MDM-RE is able to determine that the utility has crashed to unlock the resources automatically. The

lockmgr

utility can be used to manually unlock resources in the rare circumstances when automatic unlock is not possible.

System Name: Select a system from the list of available systems in the current Rulebase, to view the list of job names belonging to the system.
Job Name: Select a job name from the list of available jobs in the selected system, to view the run information.
System Logs: Check this option to see the System dependant logs.
Global Logs: Check this option to see the System independent logs.
Run-Information: The user is presented with a run information list of the selected system job. The user can at this time make a selection to view the relative step information.
Step Logs: The user is presented with a list of steps belonging to the selected job. The user can now view the run logs, error logs, output files (if any) of each step by selecting the desired option.
