How can I configure the logging for the server or agent? How do I change the logging level?

Where can I get InformixHQ?

InformixHQ is available as part of the Informix database server installation for versions 12.10.xC13 or higher.

For information, see Getting Started.

What should I do before upgrading to the latest version of InformixHQ?

Before upgrading to the latest version, it is suggested to make a backup copy of the old database file i.e. a backup copy of h2db.mv.db file. This is required in case if you ever want to revert to the previous version of InformixHQ with previous InformixHQ jar.

Where can I find sample configuration files for the server and agent?

Sample configuration files for both the InformixHQ server and agent are available in the $INFORMIXDIR/hq directory of your Informix database server installation.

For information, see InformixHQ Server Configuration and InformixHQ Agent Configuration.

How can I configure the logging for the server or agent? How do I change the logging level?

InformixHQ uses the log4j2 library for logging. By default, the InformixHQ server and agent will log messages at INFO level to an informixhq-server.log file and an informixhq-agent.log file respectively.

You can customize the logging behavior by providing a server.log4j.xml file in the current directory or classpath when starting the InformixHQ server or an agent.log4j.xml file in the current directory or classpath when starting the InformixHQ agent. Use these Log4j configuration files to change the logging level (ERROR, WARN, INFO, or DEBUG), change the log file location, or enable rolling window logging. For more information, see log4j2 and ifxhq_logging_in.html.

How do you stop the server and how do you stop the agent?

You can stop both the InformixHQ server and agent by terminating the java process that is running them.
