Oracle 10g dump file into Oracle 11g database I went through this link for my answer to the same question. I was not sure if i could continue in the same link, so created a new question. 

Oracle 10g dump file push into Oracle 11g database

Sorry if I am wrong.

When I used imp  with the following parameters:

file=my.dmp log=my.log fromuser=myuser touser=myuser statistics=none, ignore=y, full=y


I got the following errors:

IMP-00058: ORACLE error 12560 encountered
ORA-12560: TNS:protocol adapter error
IMP-00000: Import terminated unsuccessfully


Also this error message was there 


  the procedure entry point longjmp could not be located in the dynamic link library ORAUTS.DLL


The database and devsuite home are installed on Windows in two different drives. I found some references saying I should run the datapump import commands from the 11g home, with this:

set ORACLE_HOME=C:\app\Administrator\product\11.1.0\db_1
set ORACLE_SID=ORCL11R1


I am new to this Oracle database. Should this command be run in command prompt, since the installation is done on Windows, is it "set ORACLE_HOME"?

Any suggestion on this would be welcomed.
That error is most likely due to incorrect environment settings indeed, probably your PATH is mixed up too.

In a command prompt, assuming that your Oracle 11g home is indeed as you posted above, run:

set ORACLE_HOME=C:\app\Administrator\product\11.1.0\db_1
set ORACLE_SID=ORCL11R1
set PATH=%ORACLE_HOME%\bin;%PATH%


Make sure you can connect with sqlplus, then start imp.

(Do consider using the expdp/impdp Data pump tools instead though. imp/exp are essentially deprecated in 11g.)
