Why am I unable to show Ecplise-Plugin after successfully installed?

问题

I am unable to use Eclipse-Plugin after install it into Eclipse IDE.

Same thing happen with all Most time with me, while going to install any plugin either it is from MarketPlace or from ZIP.

For example, just right now i have installed Toad-Eclipse-Plugin & after installing it while i am going to open it from

Window -> Open Perspective -> Other

i am unable to show it over there into list.

So , finally i am unable to use it.

Same scenario i feel before with while installing Maven-Plugin.

Can anybody guide me here what is the exact way to install any plugin into eclipse and use it in a right manner ? ( especially Toad-Eclipse Plugin )

I have tried both way,

1. Installing from Market Place
2. First Download Zip and extract it and add to then Install New Software...

My Current Perspective after Installing Toad-Eclipse-Plugin is as per below screen shot : ( that installed plugin needs to be here but not come up why ? )

If Any Help Appreciate....!!

Ideally, both the approaches which you've mentioned should work.

1. Installing from Market Place
2. First Download ZIP and extract it and add to then Install New Software...

Then, eclipse has to be restarted to apply the new changes.

However, sometimes eclipse won't load new plugins due to OSGI registry caching issues. This can be solved by launching eclipse in clean mode.

To launch eclipse in clean mode. Go to the terminal.

eclipse -clean

In mac OSX, go to terminal

cd  /eclipse/Eclipse.app/Contents/MacOS
./eclipse -clean

To understand more about clean mode: How to run eclipse in clean mode? and what happens if we do so?
