11.8 Release All Configuration Locks

When certain configuration operations are in progress, software locks are set to warn other users who may
attempt configuration of the same item simultaneously (e.g., User 2 attempts to configure Summary 10
when User 1 has already begun configuring Summary 10). This applies to the following configuration oper-
ations:

Graphics (locked by model name)

Summaries (locked by index number)

1

Trends (locked by index number)

Security functions, including:

Function Access

Default Configuration

User Login

Security Activation

Normally a message is displayed (similar to

Figure 11-27

), warning the second user that another user is

already configuring an item, and providing an option to override the configuration lock.

Click Yes to go ahead and override the lock, or click No to exit without attempting to configure the item.
Click Info to exit the warning window and open a window (similar to

Figure 11-28

) which lists the other

users currently engaged in configuration of the item. The information provided about these users includes
the node each is logged in on, the node name (under the heading Terminal), and the time each com-
menced configuration.

If more than one user has an item open for configuration, the only changes which will take effect will be the
set of changes made by the last user to save the item.

If an abnormal condition arises while a configuration operation is in progress (a Micro-PWC shutdown as
the result of a power failure, for example), the configuration lock will remain set when the system is recov-
ered. The last item on the Utilities menu, Release All Config. Locks, is used to clear all such “lost” configu-

1.

Note that all groups in a Summary are locked when any one group in that Summary is being configured.
