Compression - Job Queue Manager

When Job Queue Manager writes the table output result to the database, it compresses the data. By default, the compression level is set to level 5, which is a compromise between size and speed.

You can change this setting:

• Setting a value lower than 5 increases the file size considerably, but runs slightly faster.
• Setting a value higher than 5 reduces the file size slightly, but runs considerably slower.
• Valid values are 1 to 9 (inclusive).

Change the Compression Level

To change the compression level:

1. Go to the Tomcat instance that is running Job Queue Manager and open <tomcat_home>\webapps\queuedjobservice\WEB-INF\config\common\service-config.xml in a text editor.
   
   

   Make a backup copy of this file before making any changes.

2. Locate the following line:

   XML

   <property name="compressionLevel" value="5"/>

3. Change the value to your preferred level. For example:

   XML

   <property name="compressionLevel" value="3"/>

4. Save your changes.
5. Restart the Tomcat server that is running Job Queue Manager.
