Special Forums UNIX and Linux Applications Infrastructure Monitoring Test if Oracle listener is running Post 302429766 by abdul bari on Tuesday 15th of June 2010 12:41:42 PM

The script looks like below.

Code:
if [ -z "$tnsping ora_tns_name |grep TNS- "]; then
        echo "Listener and TNS are working";
else
echo "Listener and TNS are not working";
fi

if tns is working value of "$tnsping ora_tns_name |grep TNS- " is null ( i mean no o/p).

otherwise it gives some value.

can you suggest how to proceed with the above if condition.

Thanks again.

VALGRIND(1)							   Release 3.7.0						       VALGRIND(1)

NAME
valgrind-listener - a simple listener program for valgrind log redirection SYNOPSIS
valgrind-listener [--exit-at-zero|-e] [port-number] DESCRIPTION
valgrind-listener is a tool to be used in conjunction with Valgrind's ability to redirect its commentary output to a network socket (by means of the --log-socket option). valgrind-listener accepts connections on the specified port and copies whatever it is sent to stdout. It can accept simultaneous connections from up to 50 Valgrinded processes. In front of each line of output it prints the current number of active connections in round brackets. port-number changes the port on which to listen for connections (default is 1500). It must be between 1024 and 65535. The same restriction applies to port numbers specified by the --log-socket option to Valgrind itself. Please note that killing the listener doesn't actually kill the processes sending data to it. OPTIONS
-h --help Show the help message. -e --exit-at-zero Causes the listener to exit when the number of connections falls back to zero (the default is to keep listening forever). SEE ALSO
