# General Information for a UNIX/Linux Installation

This section covers general information for a UNIX/Linux Installation.

# Sample Metadata, Data, and Other Tutorial Samples

The WebFOCUS Reporting Server browser interface has a feature on the ribbon and on the application tree (under new), Tutorials (the Create Tutorial Framework page), which has a pull-down select list for various samples. The ibi Data Migrator desktop interface also has this feature on the application tree.

There are currently about 10 different tutorial/sample selections available on the pull-down select list to match various customer needs. The bulk of the prior IBISAMP sample objects can be generated by selecting the Create Legacy Sample Tables and Files tutorial. Other prior IBISAMP ibi Data Migrator sample objects (usually starting with the characters dm*) are now loaded by choosing their respective ibi Data Migrator tutorials. Under the new method, the tutorials/samples may be loaded to any application, not just IBISAMP.

If you are doing just a software refresh, the prior IBISAMP objects remain unchanged (because a refresh does not touch app directories).

# Java Listener JVM Defaults

The Java Listener on AIX has a pre-set value for Maximum Java Heap Size (JVM_MAX_HEAP) because the internal default for Java for this heap size is insufficient, which causes server features to fail. The pre-set value does not reflect any specific tuning, but is simply a known working value. Specific tuning should be done based on application needs.

Other UNIX/Linux operating systems have not shown issues with internal defaults, and are not pre-set. However, applications may benefit from tuning, and it should be done based on application needs.

# Tune the Java Listener From the WebFOCUS Reporting Server Browser Interface

To tune the Java Listener from the WebFOCUS Reporting Server browser interface:

Procedure
1. Select Workspace from the menu bar.
2. Open the Java Services folder.
3. Right-click DEFAULT and select Properties.

   The Java Services Configuration pane opens.

4. Expand the JVM Settings section.
5. Under Non-standard JVM options, enter values in the Initial Java Heap Size and Maximum Java Heap Size fields.
6. Click Save and Restart Java Services.
