Since you have Oracle Support, I would suggest that you ask them, or go on MOS page and look at the desupport matrix.
Typically, their basic support is 5 years from date of release.
If it is older than 5 years, then you can pay for extended support.
There are also more expensive extended support options as well.
For future reference, I might also suggest that your title line for your posting contain more than the word "Help", and that you choose the appropriate forum for your question(s).
