Hello
I Have Oracle 10gR2 in /u10/oracle/BASE/product/10.2.0.1 with 1 database.
I now installed Oracle 11gR2 in /u10/oracle/BASE/product/11.2.0.1 and during the Installation of RDBMS, i selected the option to install sample database 'orcl'.

The DBCA failed with an Error message ' ORA-12560: TNS:Protocol Adapter Error'.

I changed my .profile to reflect the new Oracle Home before 11g Installation.
here is how my .profile looks like.

ORACLE_BASE=/u10/oracle/BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.1
ORACLE_SID=orcl
LD_LIBRARY_PATH=$ORACLE_HOME/lib32
LD_LIBRARY_PATH_64=$ORACLE_HOME/lib
PS1='[$USER:$PWD]'
PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:/usr/bin:/usr/sbin/:/bin:/usr/ccs/bin:/usr/ucb:/etc:/usr/openwin/bin:/usr/local/bin:.:./admin
export PATH ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH TNS_ADMIN NLS_LANG EDITOR


Anyhelp is greatly appreciated. This is the First time, i am installating multiple Oracle Versions on a single Box in Solaris.

Thanks
Ron
