4.4 Configuring Environment Variables with Enterprise Manager

Use the Environment tab of the Enterprise Manager Application Server Control Console page to manage Environment Variables. From this page, you can add, edit, or delete environment variables as necessary.

The environment variables such as PATH, ORACLE_HOME, and FORMS_PATH for the Forms runtime executable (frmweb.exe on Windows and frmweb on Solaris) are defined in the Environment tab. The Listener Servlet calls the executable and initializes it with the variable values provided in the environment file, which is ORACLE_HOME/forms/server/default.env by default.

Any environment variable that is not defined in that page is inherited from the servlet engine (OC4J). The environment file must be named in the envFile parameter in the Default section of the Forms Web Configuration page.

A few things to keep in mind when customizing environment variables are:

Table 4-11, "Default Environment Variables" describes important environment variables that are specified in default.env:

Table 4-11 Default Environment Variables

Environment Variable Valid Values Purpose

ORACLE_HOME

ORACLE_HOME (default)

Points to the base installation directory of any Oracle product.

PATH

ORACLE_HOME\bin (default)

Contains the executables of Oracle products.

FORM_PATH

ORACLE_HOME\forms (default)

Specifies the path that Oracle Forms searches when looking for a form, menu, or library to run.

For Windows, separate paths with a semi-colon (;).

For Solaris, separate paths with a colon (:).

FORMS_TIMEOUT

Default: 15

Valid Values: 3 – 1440 (1 day)

Example:

FORMS_TIMEOUT=1440

This parameter specifies the amount of time in elapsed minutes before the Form Services process is terminated when there is no client communication with the Form Services.

Client communication can come from the user doing some work, or from the Forms Client heartbeat if the user is not actively using the form.

TNS_ADMIN

ORACLE_HOME/network/admin

Specifies the path name to the TNS files such as TNSNAMES.ORA, SQLNET.ORA etc.

CLASSPATH

ORACLE_HOME/jdk/bin/java

Specifies the Java class path, which is required for the Forms debugger.

REPORTS_CLASSPATH

ORACLE_HOME/jlib/zrclient.jar:ORACLE_HOME/reports/jlib/rwrun.jar

This setting is only needed if Reports applications are called from Forms applications

REPORTS_SERVERMAP

cluster:repserver

Where:

cluster is the Reports Server cluster name;

repserver is the Reports Server name.

This setting is needed if Forms applications are calling Reports applications from a Reports cluster instead of a Reports server. This setting is also needed when a Forms application calls a Reportss application using web.show_document. See Oracle Application Server Reports Services Publishing Reports to the Web for additional Reports configuration information.

ORACLE_GRAPHICS6I_HOM

<GRAPHICS6I_HOME>

These settings are only needed if Graphics applications are called from Forms applications Use Enterprise Manager to set the ORACLE_HOME value to use Graphics applications.

LD_LIBRARY_PATH

Set the LD_LIBRARY_PATH environment variable for the first time to

ORACLE_HOME/lib.

You can reset LD_LIBRARY_PATH in the Bourne shell by entering:

$ set LD_LIBRARY_PATH=ORACLE_HOME/lib:${LD_LIBRARY_PATH}

$ export LD_LIBRARY_PATH

or in the C shell by entering:

% setenv LD_LIBRARY_PATH ORACLE_HOME/lib:${LD_LIBRARY_PATH}

Oracle Forms Developer and Reports Developer products use dynamic, or shared, libraries. Therefore, you must set LD_LIBRARY_PATH so that the dynamic linker can find the libraries.



Note:

On Windows, Oracle Application Server Forms Services reads Oracle environment settings from the Windows Registry unless they are set as environment variables.
