Simultaneous Access By Multiple Users

For any type of database (standard or enterprise), multiple users can log in to the same database simultaneously. The following is a general summary of the actions that are limited when multiple users are logged in to the same database or project. These rules apply to all Synthesis-enabled applications.

To check the status of a project or its items, see Status Indicators.

Secure databases have additional rules:

Status Indicators

When you encounter a project or item that is read-only (e.g., if the OK button is disabled in the properties window or if you are unable to type in the cells of a worksheet or table), you can check the status of the project or item to see if it is locked, checked-out, restricted to selected users or currently in use. There are two places in the software interface that display the status:

Restricted Access

In-Use

The location of these icons varies depending on the software you are using:

If an item is in-use, the caption bar of the item window will display a "Locked by" status, with the name of the user who is editing that item, as in the example shown next.

To display the username of the account that is editing the item, point your mouse cursor over the In-Use icon

Tip: The application interface refreshes automatically whenever you make a change (e.g., close a project, create a resource, select a different item, etc.). If your computer will not let you edit an item that is in fact not currently being edited by another user, it could be because your computer has not been recently refreshed with the latest changes made by other database users. You can initiate the refresh manually by choosing View > Refresh.

In addition, the software employs “in use” flags within the database to record when an analysis is currently being edited by a particular user. If the refresh still does not show that the item has been released, then something might have occurred to prevent the flags from being reset correctly (e.g., a network interruption or if the software closes unexpectedly). Refer to the Reset “In Use” Flags topic for instructions on how to reset the flags throughout the database if this problem occurs.
