sqlplus startup - failure in processing system parameters I am trying to do the startup command

This is what I have done:

set oracle_sid=ORCL
sqlplus /nolog
SQL&gt; conn /as sysdba
startup


It shows this error message:


  failure in processing system parameters
  could not open parameter file "C:\Program\11.2.0\DBhome_1\Database\initorcl.ora"


I checked and found out that "initoracl.ora" doesn't exist inside this path:

C:\Program\11.2.0\DBhome_1\Database


I found a init.ora file in:

C:\Program\11.2.0\dbhome_1\dbs


I tried doing this command:

startup pfile="C:\Program\11.2.0\dbhome_1\dbs\init.ora"


It shows this error:


  invalid value given for the diagnostic_dest init.ora parameter
  the specified ADR Base Directory does not existed [C:\program\11.2.0\dbhome_1\database\]
  specific directory does not exist
  additional error information
   the filename, directory name, or volume syntax is incorrect.  


What should I do?
Set the ORACLE_SID  and ORACLE_HOME  variables properly.  They must be in upper case letters.

Second, share the content of directory. ORACLE_HOME/dbs
