Unable to stop the listener in oracle 10g

Question

when i am stopping the listener, getting following error message...

LSNRCTL for Linux: Version 10.2.0.4.0 - Production on 01-JUN-2012 12:21:31 Copyright (c) 1991, 2007, Oracle. All rights reserved. NL-00857: wrong number (0 - 1 needed) of arguments to "stop"

I am using following command to stop the listener..

$ORACLE_HOME/bin/lsnrctl stop LISTENER

when i execute the command through command prompt then it works but through java it fails.

Please help me to resolve this problem....

Answer 1

I think your java cmdStr is not correct; you can't just put a space between commands (setting the env variable then calling lsnrctl). You need to use a semicolon:

String cmdStr="env ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1;/u01/app/oracle/product/10.2.0/db_1/bin/lsnrctl stop LISTENER";

Answer 2

env is a bash command, so you can't exec it from java. You can either make that into a short shell script and exec that from java or you can do the following

String cmd = "/u01/app/oracle/product/10.2.0/db_1/bin/lsnrctl stop LISTENER";
String[] envp = "ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1";
Process proc = Runtime.getRuntime().exec(cmd, envp);
if (proc.waitFor() != 0) {
    throw new RuntimeException("exit value was nonzero");
}
