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
JavaBeans (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 Platform,
Enterprise Edition (Java EE)
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.
