Figure 27: Log File
51. ‘max_allowed_packet=32M’ needs to be added to the my.cfg file. There is not a specific place that this needs to go in the file but we highly recommend you use the spot we show here. We have used “[mysqld]” (part of the pre-made file) as a reference so you see where to add the new text.
52. Save file.
53. Restart the ‘LabMySQL’ service (Start > Administrative Tools > Services).
54. Click OK on the error message you originally received if you haven’t and then click Execute again.
Figure 28: Execute Query
55. Depending on the version of SQLyog you are using, you may be required to restart SQLyog before the database and tables will appear. For older versions, you should now see all the labtech database tables.
Figure 29: LabTech tables
56. Open the Registry Editor (click Start and enter regedit in the Search box).
57. Expand HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > LabTech
58. Right-click in the right side of the window and select New > String Value.
59. Rename to ‘SQLLOC’.
60. Double-click on ‘SQLLOC’ and enter the path to your MySQL server (e.g.,
%Programfiles%\MySQL\MySQL Server 5.5\) in the Value Data field. This is used to perform daily backups and if it is not set, there may be compatibility issues in the future when it is not set.
IMPORTANT: The path must end with a backslash (\) or your backups will fail!
Figure 30: Value Data
61. From your Services window on the LabTech server, start the following services:
a) LabTech Database Agent b) LabTech Monitoring Service
c) LabTech Monitoring Service CheckUp Util d) LabTech Redirector
Figure 31: Start Services
62. Log back in to LabTech. You should see the agents starting to check back in.
63. IMPORTANT: The last step is to go your Program Files (x86)\Labtech\ folder and create a new text file named OWNMYSQL.CTL. You can do this by right-
clicking in the folder and choosing NEW > Text document. Windows, by default will append a ".txt" to the end of the file when you rename it unless you have system file extensions unhidden. You can find this option in File Explorer by going to Tools > Folder Options, then clicking on the View tab. Be sure you did not save as OWNMYSQL.CTL.TXT. This will be an empty file so you will not have to put anything in it. It just needs to be present so that the database is not corrupted when you upgrade to the next release of LabTech.
NOTE: If the menu bar does not appear in Windows Explorer, press the [Alt] key for the Tools menu to display.
