An option that I use successfully, and simpler in my opinion, is a function
that executes GFSH commands. It uses some internal capabilities but the
simplicity of it makes it worthwhile to me.
I pass the string into my function as “gfshCommand”. This is a programmatic way
of executing create region via gfsh.
create region --enable-statistics=true --type=PARTITION_REDUNDANT --name=prices
public CommandResult executeInternal(final String gfshCommand)
throws IllegalAccessException,
IllegalArgumentException,
InvocationTargetException,
RuntimeException {
try {
ParseResult parseResult = gfshParser.parse(gfshCommand);
logWriter.fine("Executing the GFSH command");
CommandResult commandResult = (CommandResult) parseResult.getMethod()
.invoke(parseResult.getInstance(), parseResult.getArguments());
return commandResult;
} catch (CommandProcessingException e) {
throw new RuntimeException("Gfsh could not execute your command.\n"
+ "Carefully check the spelling of your options and verify that the
option is valid for the command.\n", e);
}
}
