Oracle® Database Upgrade Guide 11g Release 2 (11.2) Part Number E23633-07 writes: 
Known Issue with the Deinstallation Tool for This Release
Cause: After upgrading from 11.2.0.1 or 11.2.0.2 to 11.2.0.3, deinstallation of the Oracle home in the earlier release of Oracle Database
may result in the deletion of the old Oracle base that was associated with it. This may also result in the deletion of data files, audit files, etc.,
which are stored under the old Oracle base.

Action: Before deinstalling the Oracle home in the earlier release, edit the orabase_cleanup.lst file found in the $Oracle_Home/utl directory and
remove the "oradata" and "admin" entries. Then, deinstall the Oracle home using the 11.2.0.3 deinstallation tool.

_Ref: http://docs.oracle.com/cd/E11882_01/server.112/e23633/intro.htm#BHCEECDJ

In our case:

  • There were already no oradata and admin entries in $ORACLE_HOME/utl/orabase_cleanup.lst.
  • There was already no database file in $ORACLE_BASE/oradata. There was just a soft link to ASM disk, which includes the database.

But, deinstall tool dropped the database.

Be careful while using deinstall. if you want to keep your database, don't use it until this problem is fixed.
