Aleph Toolkit User's Guide

Aleph Properties

Aleph maintains a set of properties, similar to System properties.  When the console 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 the console 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 console.
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 console interactions to a file.
aleph.maxPEs Maximum number of PEs on console choice button.
aleph.numPEs Number of PEs to start up.
aleph.pathJava where to find java
aleph.pathJava_g where to find java_g
aleph.pathRsh where to find rsh (Unix shells only)
aleph.profile If true, dump profiling information to file.
aleph.transactionManager Transaction manager, see Config.transactionManagers
aleph.useJava_g If true, run applications using java_g.
aleph.verbosity Diagnostic messages: 0, 1, or 2 are sensible values.
 
Aleph uses other properties internally, and users are advised not to modify them.
