Several environment variables have been introduced in maintenance versions of PowerBuilder 8 and PowerBuilder 9. You can set them in a batch file that launches the application, or as a system or user environment variable on the computer or server on which the application or component runs. All of these variables can be used with PowerBuilder components in EAServer.

The variables that help you control memory management can also be used with PowerBuilder applications:

• PB_POOL_THRESHOLD
• PB_HEAP_LOGFILENAME
• PB_HEAP_LOGFILE_OVERWRITE

The following environment variables control how EAServer behaves when unhandled internal exceptions and runtime errors are raised by PowerBuilder components:

• PBOnFatalError
• PBRollbackOnRTError

When EAServer uses XSL-FOP to produce a PDF file, it writes informational and warning messages to the Jaguar log. You can prevent these messages from being written to the log file by setting the environment variable PB_FOP_SUPPRESSLOG to 1.

For more information about these variables, see Application Techniques in the compiled HTML Help.
