What you need to know

Case sensitivity

The keywords in the LTM for MVS configuration file are not case sensitive.

You can verify whether LTM for MVS accepted the correct values from the configuration file by examining the LTMLOG file. After you restart Replication Agent, LTMLOG displays the configuration parameters and values, and configuration errors, if applicable.

One line per configuration parameter

Each configuration parameter entry must be on its own line; therefore, the LTM for MVS configuration file has no line continuation character.

Duplicate parameter entries

LTM for MVS processes duplicate entries for a single parameter in the configuration file inconsistently. In most cases, the second entry overrides the first entry. Sybase recommends that you avoid using multiple entries for single parameters in the configuration file.

Optional parameters

For optional configuration parameters you do not want to use, comment out the line in the LTM for MVS configuration file by inserting the “#” (pound) symbol in the first column of the line.

Several changes were made to the syntax of the LTMCFG dataset:

  • Comments are now permitted after the configuration value.

  • Entire lines may be commented out by inserting “*” or “#”.

  • Configuration parameter names are not case sensitive.

  • Most configuration values are not case sensitive.

NoteA comment cannot follow a “blank” parameter. For example, RSSDPort= comment is not valid.

Required parameters

Do not delete or comment out any required configuration parameters.

LTM for MVS supplies default values for most configuration parameters. Change the values for these parameters for your site as needed.

Configuration errors

After modifying configuration parameters and before starting LTM for MVS, check this list for potential errors:

  • A line beginning with a blank is treated as a comment.

  • Provide valid values for all optional configuration parameters that are not commented out of the configuration file. Leaving a parameter name in an active state without an appropriate value causes syntax errors.

  • If a parameter is set to insert a null in a replicate column, make sure that column allows nulls.

  • Do not delete lines containing unused parameters. Your site may need those parameters in the future.

Adaptive Server LTM configuration parameters

LTM for MVS configuration parameters differ from Adaptive Server LTM configuration parameters.
