DB Variables Configuration

• Created by: PicsOne (Normando Hall)

DB VARIABLES

SME7 come with the most used parameters set as variables. These variables are used for pass values to final configuration files. Please, read the SME Server Developer's Guide to understand the template and DB process.

These variables are useful to configure your system simply.

Without DB Variables you must following this process:

• If you need to modify a PHP.INI parameter, usually you need to create a custom-template file, and expand.
  • Make the custom directory
  • Copy the original template file to custom directory
  • Modify the file and save
  • Expand
  • Restart service

With DB Variables:

• The same example above, but with dbvar, execute the following command, expand and restart. In some configuration not need to restart because some signal-event make the necesary expansion and service restart, for example ibay-modify
  • db dbfile setprop key prop1 val1
  • Expand
  • Restart

Suppose you need to increase "memory-limit" in php.

You only execute this sentences:

db configuration setprop php MemoryLimit 64
expand-template /etc/php.ini

and then restart httpd service.

It is VERY IMPORTANT to type correctly, because the variables and keys are case sensitive, but if you make a mistake there are no error to alert you about that, and you think the configuration has changed, but really not changed.

These variables are located in files. Again, refer to Gordon Dev Guide.

The next is only the standard variables defined that come with SME7. Of course you can update this list with new standard variables in future SME versions. I organizing this long list with three columns. The first is the variable, the second is the target variable (located in the final configuration file), and the third is the default value.
