Security patches.

Does security patches need to be applied when you don't have the necessity to apply?

Applying them is a precautionary measure or unwanted trouble.

Guru's and techies in this field know this better.

Oracle releases may be 3 to 4 patches a year means every quarter your production db's cannot be updated with a patch.

well do you want to be protected or not? - its a simple question

Jan, July and Oct every year ORacle releases the security patch. Would you do recommend to apply the patches every quarter?

I have my databases secure between double firewall and no transactions go out side the lan nor do any come in. In this case why i need one.

I want to know the experts practice in real world

Thanks for your time.

again, do you want to be protected or not - its your choice
