Preparing the New Oracle Home for Upgrading
To prepare the new Oracle home in a new location, check to see if you must move configuration files, or complete other tasks.
-
Adjust your parameter file in the new Oracle Database release by completing the following steps:
-
Remove desupported initialization parameters and adjust deprecated initialization parameters. In new releases, some parameters are desupported, and other parameters are deprecated. Remove all desupported parameters from any parameter file that starts the new Oracle Database instance. Desupported parameters can cause errors in new Oracle Database releases. Also, alter any parameter whose syntax has changed in the new release.
AutoUpgrade run with the
-preupgrade
parameter inanalyze
mode displays any deprecated parameters and desupported parameters it finds in theupgrade.xml
file that it generates.Adjust the values of the initialization parameters to at least the minimum values indicated in
upgrade.xml
Ensure all path names in the parameter file are fully specified. You should not have relative path names in the parameter file.
-
If the parameter file contains an
IFILE
entry, then change theIFILE
entry in the parameter file. TheIFILE
entry should point to the new location text initialization parameter file that you specified in step 1. Also edit the file specified in theIFILE
entry in the same way that you edited the parameter file in step 1. -
If you are upgrading a cluster database, then if necessary, you can modify the
SPFILE
orinitORACLE_SID.ora
files.
After making these parameter file adjustments, make sure that you save all of the files that you modified.

-
(Manual upgrades only) If you are upgrading a cluster database, and you are not using AutoUpgrade or Replay Upgrade, then you must manually separate the database instance from the cluster. Set the CLUSTER_DATABASE initialization parameter to
false
. After the upgrade, you must set this initialization parameter back totrue
. If you are using DBUA, then the assistant takes care of this task for you.
