Aleph Toolkit User's Guide

Aleph Properties

Aleph maintains a set of properties, similar to System properties.  When Aleph is started, any system property that starts with the string "aleph." is encorporated into the Aleph properties.  Aleph properties can be created and queried by calls to Aleph.setProperty() and Aleph.getProperty().  When Aleph creates a new PE, all its current Aleph properties are passed to the PE.

The following properties may be useful, either as command-line arguments, or to check at run-time.
aleph.batch If true, start application without the desktop.
aleph.communicationManager Communication manager, see Config.communicationManagers
aleph.directoryManager Directory manager, see Config.directoryManagers
aleph.eventManager Event manager, see Config.eventManagers
aleph.label PE's print name (default PE[n]).
aleph.logging If true, log desktop interactions to a file.
aleph.maxPEs Maximum number of PEs on runtime window choice button.
aleph.numPEs Number of PEs to start up.
aleph.pathJava where to find java
aleph.port talk to Aleph servers listening on this port.
aleph.pathRsh where to find rsh (Unix shells only)
aleph.transactionManager Transaction manager, see Config.transactionManagers
aleph.verbosity Diagnostic messages: 0, 1, or 2 are sensible values.
