STEP 2.create auxiliary structure AT 'SERV2'
mkdir auxl
cd auxl
mkdir admin oradata admin/create admin/diag admin/pfile oradata/control oradata/log oradata/data oradata/archive


STEP 3.edit clone pfile only and  not to source db
SQL> create pfile='/home/oracle/initauxl.ora' from spfile;
File created.
[oracle@serv1 ~]$ scp /home/oracle/initauxl.ora oracle@192.168.62.129:/home/oracle/axul/admin/pfile/

----------------------------------------------------------------
target pfile 
db_name=source
sga_target=500m
control_files='/home/oracle/target /oradata/control/control01.ctl'
diagnostic_dest='/home/oracle/target /admin/diag'
undo_tablespace='UNDOWW'
-----------------------------------------------------------------

log_file_name_convert='/home/oracle/target/oradata/log','/home/oracle/auxl/oradata/log'    -----not necessary so remove this one may be ur choice
undo_tablespace='UNDOWW'


STEP 4. create password file
AT 'SERV1'
cd $ORACLE_HOME/dbs
export ORACLE_SID=target
orapwd file=orapwtarget password=sys force=y

AT 'SERV2'
cd $ORACLE_HOME/dbs
export ORACLE_SID=auxl
orapwd file=orapwauxl password=sys force=y

AT 'SERV3'
cd $ORACLE_HOME/dbs
export ORACLE_SID=catlog
orapwd file=orapwcatlog password=sys force=y


STEP 5.startup the auxiliary  upto nomount
export ORACLE_SID=auxl
sqlplus / as sysdba
startup pfile='/home/oracle/auxl/admin/pfile/initauxl.ora' nomount;

STEP 5.CREATE REPOSITORY CATLOG USER AT CATLOG DATABASE AND CONNECT ALSO AUXILIARY DB(RUN BELOW SCRIPT) OR U CAN  COPY AND PASTE LINE BY LINE.

vi ruser.sh at serv3
export ORACLE_SID=catlog
sqlplus / as sysdba   <<EOF
startup;
alter system set db_create_file_dest='/home/oracle/catlog/oradata/data/' scope=spfile;
