If your site has installed 10g, what $ORACLE_HOME setting are you using? Historically, we've used the format $ORACLE_BASE/product/release, so that for say, 9i, we would see: $ORACLE_BASE/product/9.2.0.2 $ORACLE_BASE/product/9.2.0.4 Oracle has tweaked the OFA so that it now recommends ORACLE_HOME be=20 set like this: $ORACLE_BASE/product/10.1.0/{type}_{counter} where type is the product name: db - database server, client, etc So for our first enterprise install, ORACLE_HOME would be set thus: $ORACLE_BASE/product/10.1.0/db_1 (which actually is version 10.1.0.2) Now, let's say we want to patch to 10.1.0.2. What we would do is clone db_1=20 into db_2 and then patch the db_2 version, giving us: $ORACLE_BASE/product/10.1.0/db_1 $ORACLE_BASE/product/10.1.0/db_2 Oracle cites the advantages of the new OFA structures as: o You can install different products with the same release number in the same=20 $ORACLE_BASE o You can install the same product more than once in the same $ORACLE_BASE However, it's not visually apparent as to the specific release you are looking=20 at when perusing the directory structure under the new OFA structure. =20 Thanks!
