Pervasive Monitor Topics |

Resource Usage Tab |
Overview
View and/or disconnect Pervasive users accessing the RDP system. Similar to the Pervasive’s Monitor feature in that it allows viewing the active user connections, open files, and resource usage. The Monitor Users form is organized into four tabs: Users, Files, Resource Usage, and Lock/Unlock RDP.
The first time the User Monitor is accessed, the user is presented with a logon screen requiring administrative information before proceeding. Enter the Administrator logon and password. For more information, see Adding an Administrative User. Once the directories and connections are created, the administrator information is stored.
Users Tab
To access the Pervasive Monitor, select Monitor Users from the Audit/Day End submenu.

Each user is represented by a user name (typically the login ID of the user) or by an index into the engine’s client (user) list.

Each client is represented by either a user name (typically the login ID of the user) or an index into the engine’s client (user) list.

Files Tab
The fields and buttons available on the Files tab display the same information as those on the Users tab, EXCEPT that the field values pertain to the files listed in the Active MicroKernal Files list (and not the users).

- Read-only Flag
- Displays Yes when the selected file is accessed by the user in a read-only (non-changable) fashion and No when the file is writable.
- Record Locks
- Displays Yes when the selected file is accessing a record which renders it locked by the user. When No, the selected file does not have a record locked by the user.

Lock/Unlock RDP Tab
- Seconds to Display Warning Message on Workstations
- Configure the length of time in seconds (default setting is five seconds) the disconnection warning displays on users' workstations
- Minutes to Allow Users to Exit RDP
- Configure the length of time in minutes (default setting is five seconds) any and all users are given to complete projects and exit the system prior to being disconnected by the Lock Users Out of RDP button.
-
Lock Users Out of RDP - Click the "Lock Users Out of RDP" button to perform the lock.
When the system is locked, an "Update" lock record is placed in the Lock File (lockfile.dat). The standard utility message appears on the RDPWin and RDP-DOS logon screens. The RDPWin logon screen checks every 30 seconds for removal of the lock. When a user is in the system and the is system locked, then each time a function is chosen either from the main menu or the tool bar, a message displays that there has been a request to lock the system and all users should exit.
When the Lock/Unlock Logon is used to lock the system prior to running a utility, then once the utility is started, the Lock File is deleted and the Update is removed from the system. However, the UTIL lock for the utility running is still in the system, so all users are still locked out. Once the utility has finished, all users are allowed back into the system without accessing the Lock/Unlock Logon again.
Once locked, the administrator can exit RDPWin and apply the RDP update. The only workstation allowed back into the system is the workstation that originally executed the lock. - Allow Users in RDP
- Once users have been locked out of RDP, the "Lock Users Out of RDP" button title changes to "Allow Users In RDP". Click to perform the unlock (remove the "Update" lock record in the Lockfile.dat). The RDPWin logon screen checks every 30 seconds removal of the lock and allows access to users once the lock is removed.
