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.
for upgrading you can also use the upgrade assistant dbua
it takes most of the manual work out of the way
where you use opatch:
install base software 10.2.0.1 (using oracle universal installer = oui)
install patch software 10.2.0.4 (using oracle universal installer = oui)
apply patches (using opatch)
there are more links on support.oracle.com (search for dbua)
