I am new to Oracle and have a question in my mind about Oracle OPatch tool.
I am using Oracle 10.2 -
(1). Is OPatch a dedicated tool for Oracle Database patching? if not what are the other usage of OPatch?
(2). Can we use OPatch to upgrade Databases? (Ex - upgrade 10.2 to 11.1)
(2). if upgrade my Opatch tool with latest version, Still can I use my OPatch Tool (Upgraded) to patch my 10.2 Oracle Database?
Or should I keep my old OPatch tool for patch up 10.2 Database?
Thank You in advance.
