Compression

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.
