Configuring the LTM

You control LTM behavior by modifying the LTM configuration file, which is a plain text file created and edited using a text editor. The LTM configuration file contains information the LTM needs, such as the SQL Anywhere server it transfers a log from, the Replication Server it transfers the log to. You need a valid configuration file to run the LTM.

Creating a configuration file

You must create a configuration file, using a text editor, before you can run the LTM. The -C LTM command specifies the name of the configuration file to use, and has a default of dbltm.cfg.

Configuration file format

The LTM configuration file shares the same format as the Replication Server configuration file described in your Replication Server Administration Guide. In summary:

  • The configuration file contains one entry per line.
  • An entry consists of a parameter, followed by the = character, followed by the value: 
    Entry=value
  • Lines beginning with a # character are comments ignored by the LTM.
  • The configuration file cannot contain leading blanks.
  • Entries are case sensitive.

For the full list of available configuration file parameters, see The LTM configuration file.
