SQL problem with zenOn 6.21 - huge project-log file

The project-log file (SQL Server Database Transaction file) in the SQL directory of the project constantly grows and requires several GigaBytes on the harddisk


Under very specific circumstances it can happen that the shrink action (especially doing it via the batch file) leads to a corrupt Log-File and thus the Database itself can not be read anymore.

Due to some reasons the SQL-Log-File of a database can reach indeed a very huge size (this behaviour belongs to default settings of the MS SQL Server).
However, it is possible to shrink this file (Note: do not delete this Log-File!! Otherwise important links can get lost and the project itself would be corrupt).
On the zenOn DVD there exists a SQL-Manager Software which can handle this issue (see Additional_Software\MSSQL_Express\ -> SQLServer2005_SSMSEE.msi)

Please follow the steps below after you have installed the software mentioned above:

  • create a project-backup (just for safety)
  • start the program SQL Server Management Studio Express
  • connect to the SQL Server (probably SQL Server (ZENON_DEV))
  • select the database (GUID) which should be shrinked (i.e. 0b1b379e-7a6d-43b6-9aa6-39cc5065c984)
  • right-click at this database and select properties ("Eigenschaften")
  • go to options ("Optionen") and at the recovery model ("Wiederherstellungsmodel") choose simple ("einfach") and close this dialog
  • right-click at the database again, choose tasks -> shrink database -> files ("Aufgabe -> Datenbank verkleinern -> Dateien")
  • select at datatype protocol (Project_Log will be automatically choosen at filename)
  • after pressing OK the Log-File will be shrinked (this process needs about 2-3 seconds -> depends on the size)
