Symptom: When opening a database you receive an error that the database is currently unavailable.
Cause
System resources can limit the number of databases On-Screen Takeoff® and Quick Bid can have open at the same time. All open databases appear on the Bids Tab in On-Screen Takeoff and in the Bid Navigator in Quick Bid.
Resolution
To resolve this issue, click File > Open and uncheck some of the open databases in the Open Databases window. This should free up system resources and allow you to open other databases.
If you continue to receive this error, the
database may be damaged. Please perform a Compact and Repair using Microsoft's Access program and then try to re-open the
database.
Symptom: When attempting to open a database, you receive an error message that the database i no longer available or unrecognized format
Error mesage:
The database is no longer available. Please check with your database administrator regarding this problem.
If you attempt to open the database in Microsoft Access, you will receive this error message:
Unrecognized database format...
Cause
This indicates that the database is no longer usable. This is normally caused by an immediate (even temporary) disconnection between the user and the resource (drive) where the database is stored and or a power interruption (causing the same disconnect).
For example, if a user has a network database open in an On Center Software application and his or her connection to the network is lost, the database is left in an unusable and, usually, un-correctable state. This can also happen with a local database if the machine immediately loses power (like a power failure or the cord being unplugged).
Resolution
The only way to recover from this is to restore the database from a previous backup - you will lose all work performed since that backup was created. See Related Articles for information on backing up and restoring databases.
Symptom: When opening a database, you receive an error stating that the database needs to be repaired, or is no longer a valid database file.
Selecting to repair the database results in the following error:
Windows cannot find C:\Program Files\Common Files\On Center Software\Server\JetComp.exe.
Cause
When communication with a database is immediately terminated, due to a power outage or a lost network connection, or an unexpected application termination, the database may become inaccessible. JetComp.exe can be utilized to repair the database and resolve this issue.
Resolution
To resolve this issue, perform the following steps.
Download the following file based on your Operating System type:
Once downloaded, double-click the EXE file and click Unzip to automatically copy JetComp.exe to the correct directory.
Once extracted, attempt to open the database again - the database should be automatically repaired without prompting.
Additional information on JetComp.exe is available in the Summary section of the following Microsoft Support Article: Article ID: 295334 - http://support.microsoft.com/kb/295334.
This only affects Microsoft Access-type databases.
Be sure you are providing adequate backups of your
database(s). See Related Articles for information on backing up Access-style databases.
