SQL Server stopped due to oversized Transaction Log.

Article summary

The Pharos Principal Server is not functioning correctly as the hard drive is full. The Pharos Database Transaction Log is using all available HD space.


This can happen if the SQL Server Agent is never turned on. When backups are run, the log is truncated, making it smaller.

To free up the space in the SQL Server Transaction Log for the Pharos Database, follow these steps:

  1. Close all connections to the Pharos Database on SQL Server by stopping the Pharos Database Service and any dependant Pharos services. Also close any copies of Pharos Reports that may be running.

  2. Open SQL Query Analyzer, logging on as 'sa' or a user with System Administrator rights and run the following SQL query:

    sp_detach_db 'pharos'
  3. Open Windows Explorer and browse to a location where the SQL Server data files are located. (i.e. c:\MSSQL7\Data). There should be two files related to the Pharos Database (pharos_data.mdf and pharos_log.ldf). Delete the old log file that is now too big (i.e. pharos_log.ldf). You may need to delete the file from the Recycle Bin as well.

  4. Switching back to SQL Query Analyzer, run the following SQL query:

    sp_attach_single_file_db @dbname ='pharos', @physname = 'c:\MSSQL7\Data\pharos_data.mdf'
  5. Restart the Pharos Services (starting with Pharos Database Service)
