You posted this to a publicly readable online forum.
Are you sure you want to display all that internal contact information to the Universe?
Do you think those people want you to broadcast their details to where spammers and identity thieves can harvest it?
I suggest you find some sort of internal help resource for whatever you are trying to do (ask your department supervisor if necessary) and then edit your initial forum post to delete all that information.
Thanks for the information. I didn't realize that all the data will be visible. I have removed the contents.
Can you help me in removing the post. I mean i want to delete the post.
There are company-internal resources for assistance with company-internal issues.
There are MOS forums available through a MOS login, readability limited to anyone with a MOS login, so that one is quasi-public.
... then there are these public-readable forums-dot-oracle-dot-com that are for the generic user community -- readable to anyone in the world regardless whether logged in or not.
I think you may need to take some time to get familiar with where you need to seek help for each individual occasion.
In the mean time, I have arranged to have this thread locked.
The text in it may help others in the future to pause for a moment before joining and posting.
