Hello all,
We use Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production. We try to upgrade our development server from 11.2.0.4 to 12c using DBUA. But after Pre-Upgrade tasks it gives the below error messages,
ORA-01034: ORACLE not available
ORA-01092: ORACLE instance terminated. Disconnection forced
ORA-00704: bootstrap process failure
ORA-39700: database must be opened with UPGRADE option
Though I ignore and proceed further, upgrade assistant fails. I have set all the environment variables correctly and checked that the source DB is up before this upgrade. However I noticed one more thing, Step 2 screen of DBUA (Refer https://docs.oracle.com/database/121/UPGRD/upgrade.htm#UPGRD52860 . Section 3.2.3 - screen 2 shows the screen mentioned here) which displays the Source DB and Target DB shows below information,
Source Database Oracle Home: /u01/app/oracle/product/11.2.0/dbhome_2
Source Database Version:11.2.0.4.0
Target Database Oracle Home: /u01/app/oracle/product/12.1.0/dbhome_1
Target Database Version:12.1.0.1.0
Below this is a "Select Database" option displayed with the database information as given below,
Name Release Status Type
orcl 11.2.0.1.0 Up Single Instance
I believe that the release version above should be the same as the source database version. But due to some reason, the DBUA shows a wrong version here and i guess this could be a reason for this failure. I have recently upgraded this database from 11.2.0.1.0 to 11.2.0.4.0 using DBUA and this was successful. Can anyone explain where does DBUA get this release information give above? Can anyone help me to solve this problem?
Thanks in advanca
