There are a number of options to consider when setting the Synch
to OS Thread Allowed option.
With the Synch to OS Thread Allowed support:
- The application developer or assembler requests behavior by setting the
special application environment entry env-entry in the deployment descriptor: com.ibm.websphere.security.SyncToOSThread=true|false.
- The system administrator grants the request made by the application developer
or assembler using an application server configuration setting.
- The resource access control facility (RACF) administrator
controls if Synch to OS Thread Allowed can be used by defining a FACILITY
class profile with an optional SURROGAT class profile to refine the control.
You can select the
Synch to OS Thread Allowed option at development
time or at assembly time:
- At development time, use Rational Application Developer to add an environment
entry (environment variable) to the Enterprise JavaBean (EJB) component or
Web application module.
Important: Environment entries (environment
variables) can be defined on individual EJB components but cannot be set on
individual Web components.
A Java 2 Platform, Enterprise Edition
(J2EE) standard deployment descriptor can be defined for each EJB component
and for each Web application module. Note that a Web component is either a
servlet or JavaServer Pages (JSP) files. For Web components, environment entries
(environment variables) can only be set on a Web application module. A Web
application module contains servlets and JSP files.
- At assembly time, you can add or change environment entries
(environment variables) using an assembly tool. For more information, see
"Starting WebSphere Application Server Toolkit" in the Application Server
Toolkit documentation.
