the listener status

there multiple reasons issue:

recently faced similar problem oracle 11g on windows 7 machine. found in services.msc, oracleoradb11g_home1clragent not started , startup type set manual.

i changed startup type automatic , started oracleoradb11g_home1clragent manually, after able connect properly.

so basic reason oraclragnt isn't running.

for other reasons can check this link.
