Configuration Monitoring 

Use

This function enables you to monitor the open configuration objects for both reading and writing, as well as to view information about existing blocking locks on configuration objects. You can force the release of a blocking lock and also close a configuration object if you need to terminate a read or write operation on the object.

Activities

The function is available in the Runtime tab of the Configuration Adapter Service in the Visual Administrator.

The Open configurations tab displays the following information about the configuration objects that are currently open:

·        Path – the location of the configuration object in the database

·        Mode – the access mode for the configuration object; its value is either Read or Write, depending on which operation is performed on the object

·        Cluster ID – the ID number of the cluster element where the configuration object has been opened.

The Blocking locks tab displays the following information:

·        Path – the location of the locked configuration object

·        Transaction ID – the ID number of the transaction that has locked the configuration object

·        Waiters – the number of threads currently waiting for access to the configuration object

·        Mode – the mode of the blocking lock; it depends on the type of the operation on the configuration object – either Read, or Write

·        Cluster ID – the ID number of the cluster element where the configuration object is locked

·        Seconds – the time during which the lock has been active.

You can request detailed information about the open configurations and the blocking locks both in the Open configurations and Blocking locks. To do this, choose Show details.

You can terminate the operation on a configuration object and close it by selecting it in the list, and choosing Close selected configurations in the Open configurations tab.

You can release a lock on a configuration object by selecting it in the list, and choosing Remove selected blocking locks in the Blocking locks tab.
