Creating Database Using DBCA got ORA-01034: ORACLE not available

My oracle file permission was wrong.

--Before
[oracle@bwdhdbpr060 bin]$ ls -la oracle
-rwxr-x--x  1 orashp oinstall 232399041 Jul 27 15:05 oracle

--After

[oracle@bwdhdbpr060 bin]$ chmod 6751 oracle
[oracle@bwdhdbpr060 bin]$ ls -la oracle
-rwsr-s--x 1 oracle oinstall 203972171 Jul 25 19:24 oracle


Also, unset ORA_CRS_HOME from your database OS user before starting dbca.

This fix my problem.

netca got error ServiceAliasException: Could not initialize Service Alias: TNS-04404: no error caused by: oracle.net.config.ConfigException: TNS-04414: File error caused by: TNS-04612: Null RHS for "BWWLPR"

O got this error below while trying to create a listener using netca in a RAC 10g.

############################################################################

ServiceAliasException: Could not initialize Service Alias: TNS-04404: no error
  caused by: oracle.net.config.ConfigException: TNS-04414: File error
  caused by: TNS-04612: Null RHS for "BWWLPR"
############################################################################

The problem was that netca is not recognising my service name BWWLPR as below:

############################################################################

BWWLPR =
(DESCRIPTION =
  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = xxxxx1.b2w)(PORT = 1525))
    (ADDRESS = (PROTOCOL = TCP)(HOST = xxxxx2.b2w)(PORT = 1525))
    (ADDRESS = (PROTOCOL = TCP)(HOST = xxxxx3.b2w)(PORT = 1525))

    (ADDRESS = (PROTOCOL = TCP)(HOST = xxxxx4.b2w)(PORT = 1525))
  )
  (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = BWWLPR)
    (FAILOVER_MODE =

 (TYPE = SELECT)
      (METHOD = BASIC)
      (RETRIES = 180)
      (DELAY = 5)
    )
  )



############################################################################


To fix this issue I added the line "(DESCRIPTION = " to the first line like below:

"BWWLPR = (DESCRIPTION ="

It works for me.

Clone RAC 11g Binaries to Single Instance

1.      Copy OH from source to target:

cd /dbotm/oracle/products

find 11.2 -print | cpio -ov > /media/binario_OTM/OH_otm.cpio           

scp /media/binario_OTM/OH_otm.cpio orabpel7@10.3.0.31:/midias/binario_OTM            

2.     Create OH on new target:

mkdir -p /dbbpel7/oracle/products/11.2

3.     Uncompress:

cd /dbbpel7/oracle/products/              

cpio -idmv < /midias/binario_OTM/OH_otm.cpio

4.     Run clone.pl to clone binaries:

export ORACLE_HOME=/dbbpel7/oracle/products/11.2         

cd $ORACLE_HOME/clone/bin

perl clone.pl ORACLE_HOME="/dbbpel7/oracle/products/11.2" ORACLE_HOME_NAME="OH_BPEL7" ORACLE_BASE="/dbbpel7" OSDBA_GROUP=oinstall OSOPER_GROUP=dba

5.     Don't forget to run as root:

cd $ORACLE_HOME

./root.sh    

6.     Fix inventory(if necessary):

cd $ORACLE_HOME/oui/bin

./runInstaller -clone -silent -ignorePreReq ORACLE_HOME="/dbbpel7/oracle/products/11.2" ORACLE_HOME_NAME="OH_BPEL7" ORACLE_BASE="/dbbpel7" oracle_install_OSDBA=oinstall oracle_install_OSOPER=dba

7.     Finally, change RAC to OFF:

cd $ORACLE_HOME/rdbms/lib

/usr/ccs/bin/make -f ins_rdbms.mk rac_off

make -f ins_rdbms.mk ioracle
