Interactive mode allows you to start a session on a working node with specific resource. To initiate a interactive mode, use qrsh command.

To reserve 4G for 10 hours ( Note: The job length cannot be more than 24 hours without "highp")
qrsh –l h_data=4G,h_rt=10:00:00
To reserve 2 cores with 4G memory for 8 hours ( Note: Total memory reserved will be 2 x 4 = 8GB)
qrsh –l h_data=4G,h_rt=8:00:00 –pe shared 2
To reserve for jobs longer than 24 hours needs “highp” (CCN contributed nodes)
qrsh -l h_data=4G,h_rt=72:00:00,highp
