Changing Configuration Parameters With Scripts

Several scripts allow you to change Distribution Server configuration settings. The Distribution Server cannot start unless it can connect to the repository. If you cannot start the Distribution Server, use these scripts to correct connection settings. The scripts are installed in:

/install_directory/ibi/WebFOCUS81/ReportCaster/bin

The following scripts are available:

Script

Purpose

dbname

Changes the DB Name parameter. This parameter is only needed when using a DB2 repository on z/OS..

dbpass

Changes the password used to access the repository.

dbuser

Changes the user ID used to access the repository.

repclass

Changes the JDBC class used to access the repository driver. See Additional WebFOCUS Repository Topics and Tasks for information on this value.

repurl

Changes the JDBC URL used to access the repository. See Additional WebFOCUS Repository Topics and Tasks for information on this value.

To run a script, execute it at a shell prompt with the first argument being the value you wish to set.

Warning: If a value contains a semicolon (;), you must place that value between quotation marks.



Example: Running Configuration Scripts

If during the installation you typed the wrong user ID and password to access the repository, you can change them as follows.

  1. Navigate to the following directory:
    /install_directory/ibi/WebFOCUS81/ReportCaster/bin
  2. Execute the following to change the user ID used to access the repository:
    ./dbuser userID

    where:

    userID

    Is the correct user ID to access the repository.

  3. Execute the following to change the password used to access the repository:
    ./dbpass password

    where:

    password

    Is the correct password to access the repository.

The other scripts (for example, repurl, repclass) are executed in the same fashion. If your URL or CLASS contains a semicolon (;), place the URL or CLASS between quotation marks when running the scripts.

Configuring the Memory Available for the ReportCaster Log Report

The size of the ReportCaster log report is limited by the amount of memory available to the Java VM. When the memory of the Java VM is exceeded, a Java OutOfMemoryException error occurs.

To control the size of the log report, you can set the following ReportCaster Server Configuration tool parameters:

Configuring the Heap Size for the ReportCaster Distribution Server

If the ReportCaster Distribution Server experiences a Java out of memory error, you must increase the amount of memory (heap size) available to Java on the Distribution Server. This is done by passing parameters on the Java command line, as follows:

java -Xms<initial heap size> -Xmx<maximum heap size>

For example,

java -Xms256m -Xmx512m

You must restart the Distribution Server to enable this change.

Configuring ReportCaster Failover and Workload Distribution

How to:

The Distribution Server Failover feature allows you to configure a backup Distribution Server that can resume ReportCaster operations when there is an interruption (planned or unplanned) in the primary Distribution Server service. The primary Distribution Server is monitored to verify that it is operational. If there is an interruption in service, the failover Distribution Server is triggered to take over the role of the primary server.

The Workload Distribution feature allows ReportCaster to distribute scheduled jobs across multiple Distribution Servers, providing an efficient and fast way to process large numbers of ReportCaster schedules. Multiple Distribution Servers can be installed on one or more hosts. One instance is designated as the Workload Manager, while the others are designated as Workers. The WebFOCUS Repository will be shared by the Workload Manager and the Workers. Workload Distribution is set up through the ReportCaster Configuration tool. All servers will share one set of configuration information, and the Workload Manager will push any configuration changes to the Workers.

For your application of ReportCaster, you can configure either Failover or Workload Distribution, or both at the same time. The following procedure includes instructions to configure both, but notes when to skip to the appropriate steps if you are only configuring one or the other.

Procedure: How to Configure Workload Distribution

To configure workload distribution:

  1. Open the ReportCaster Console and click Configuration in the top pane.
  2. Click the Distribution Servers folder in the left pane.
  3. Click the button to the right of the Workload Distribution field.

    The Workload Distribution dialog box opens, as shown in the following image.

  4. Select the Enabled check box.

  5. Click Add.
  6. Enter the name, host name, and port number of the Worker Distribution Server.

    Repeat this step for each Worker Distribution Server instance that you want to add.

Adding Support for UTF-8 to the Distribution Server

Support for UTF-8 can be added to the Distribution Server by adding -Dfile.encoding=UTF8 to the Distribution Server Java command. If the Distribution Server is being run from the command line, modify the schbkr bat or script file and add -Dfile.encoding=UTF8 to the Java command.

Configuring Secure Communications to the ReportCaster Distribution Server

ReportCaster encryption can be enabled to secure communications between the ReportCaster application and the ReportCaster Distribution Server. For more information, see Distribution Server Settings in the ReportCaster manual.

Configuring ReportCaster Web Services in an SSL Environment

By default, the Axis Servlet only accepts HTTP requests. If you use ReportCaster Web Services in an SSL environment, you will need to manually configure the Axis Servlet to accept HTTPS requests. To do so, add a second AxisServletListener with the name https to axis2.xml and specify the port parameter for both listeners. The axis2.xml file is located in the ibi/WebFOCUS81/webapps/webfocus/WEB-INF/conf folder.

The following code is an example of a second AxisServletListener.

<transportReceiver name="https" 
class="org.apache_1_6_2.axis2.transport.http.AxisServletListener">
<parameter name="port">8443</parameter>
</transportReceiver>

Configuring ReportCaster for Graphs

How to:

In order for ReportCaster to distribute graphs, you must either set DISPLAY or use the headless option. This is similar to the Server Side Graphics configuration discussed in Verifying and Troubleshooting Server Side Graphics (PCHOLD).

Procedure: How to Configure ReportCaster for Graphs

The procedure for distributing graphs will depend on whether you have an X Windows Server.

To distribute graphs, do one of the following:
