Hello All,


WCS installed on windows server is suddenly stopped responding to console/https etc..what should i check ...?

Correct Answer by Scott Fella about 3 years 11 months ago

Have you checked in windows if the service has stopped? Have you tried to
Stop and start wlc's again or reboot the server? I usually would do these and then verify by checking the WCS status.

Adding to what Scott suggested; try to use the latest version of WCS that is compatible with your WLCs.

The newer versions usually have more bug fixes.

Restoring the WCS Database.

If problem not solved and no other solution found, then you can restore it.

Follow these steps to restore the WCS database from a backup file on a Windows server. If you are restoring the WCS database in a high availability environment, refer to the "Restoring the WCS Database in a High Availability Environment" section.



Step 1 Log into the system as administrator.

Step 2 Perform one of the following:

•Follow these steps from the Windows Start menu:

a. Click Start > Programs > Wireless Control System> Restore. The DBAdmin and Enter Information window appears.

b. Browse to the backup directory that you created and choose the filename or enter the full path and filename of the backup file (such as C:\WCS7.0.X.X_Backup\Nov11.nmsbackup) and click OK.

< OR >

•Follow these steps from the command prompt:

a. Navigate to the WCS installation directory (C:\Program Files\WCS7.0.X.X\bin).

b. Enter DBAdmin restore backup-filename, where backup-filename is the full path and filename of the backup file (for example, C:\WCS7.0.X.X_Backup\Nov11.nmsbackup).

Step 3 If you have a large event table to migrate, you must limit the size of the event table. You cannot decline this process, but it generally only affects pre-5.1 to 5.2 or later migration. The following warning message appears:
WARNING: You are migrating from a pre-5.1 database to a post-5.1 database. This may take a very long time -- possibly several hours. You can considerably speed this migration by retaining only the most recent events from the restored database. Even if you do this, the event table will be repopulated within seven days. This does not affect current alarms. This does not affect the backed-up database.
Would you like to retain only recent events?

If you type Y or Yes (or click Yes from the GUI prompt), the restore retains only the most recent 40,000 events.

Step 4 Click Yes if a message appears indicating that WCS is running and needs to be shut down.

Step 5 The DBAdmin window appears and displays messages indicating that WCS is shutting down (if applicable) and the WCS database is being restored. Close the DBAdmin window when the Close button becomes active.
