Package and OS requirements
We can install the Oracle Provided 12c preinstall package to meet the Package and OS requirement
running the below yum command (as root):
yum install oracle-rdbms-server-12cR1-preinstall
Download the database 12c software
You need to download both Oracle Database 12c parts from the Oracle Technology Network (OTN)
Once you’ve downloaded the software, unzip both files to a staging area:
unzip /home/oracle/linuxamd64_12c_database_se2_1of2.zip -d /u50/app/oracle/software unzip /home/oracle/linuxamd64_12c_database_se2_2of2.zip -d /u50/app/oracle/software
All of the contents from the above will be extracted to a “database” directory.
Start the installation
Open an X-Windows session to the server as the ‘oracle’ user.
Once the GUI starts, respond as follows:
Choose install Database software only
Choose Single instance installation
We are here doing standard edition installation. You can do whatever licence you have
Give the location of Oracle base and Oracle Home directory
When Prompted run below scripts
When prompted, run the following as root:
/u50/app/oraInventory/orainstRoot.sh (first Oracle installations only)
/u50/app/oraInventory/orainstRoot.sh Changing permissions of /u50/app/oraInventory. Adding read,write permissions for group. Removing read,write,execute permissions for world.
/u50/app/oracle/product/18.104.22.168/root.sh Performing root user operation for Oracle 12c The following environment variables are set as: ORACLE_OWNER= oracle ORACLE_HOME= /u50/app/oracle/product/22.214.171.124 Enter the full pathname of the local bin directory: [/usr/local/bin]: <enter> Copying dbhome to /usr/local/bin ... Copying oraenv to /usr/local/bin ... Copying coraenv to /usr/local/bin ... Creating /etc/oratab file... Entries will be added to the /etc/oratab file as needed by Database Configuration Assistant when a database is created Finished running generic part of root script. Now product-specific root actions will be performed.
This conclude the Oracle Binaries installation.
Now lets do the create database
We are choosing the default option as it will ask for less question. Then click next
After prerequisite check ,database should create successfully
Post Installation Configuration Steps.
1) Set the values in .bash_profile for Oracle Environment
export ORACLE_BASE=/u50/app/oracle export ORACLE_HOME==/u50/app/oracle /product/126.96.36.199 export ORACLE_SID=TEST export PATH=/usr/sbin:$PATH export PATH=$ORACLE_HOME/bin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
2) Do the Listener Configuration
Listener Configuration:$ORACLE_HOME/network/admin/listener.ora TEST = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = TECH.com)(PORT = 1521)) ) ) SID_LIST_TEST = (SID_LIST = (SID_DESC =(ORACLE_HOME= /u50/app/oracle/product/188.8.131.52) (SID_NAME = TEST) ) )
3) TNS Configuration: $ORACLE_HOME/network/admin/tnsnames.ora
TEST= (DESCRIPTION= (ADDRESS=(PROTOCOL=tcp)(HOST=TECH.com)(PORT=1521)) (CONNECT_DATA= (SID=TEST) ) )

Known issues with Oracle 12c Installation(ALL OS)
1) Dbca/dbua gives issues
UnsatisfiedLinkError exception loading native library: njni12 java.lang.UnsatisfiedLinkError: njni12 (rtld: 0712-001 Symbol CreateIoCompletionPort was referenced from module /u01/products/rdbms_12102/lib/libnjni12.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol GetMultipleCompletionStatus was referenced from module /u01/products/rdbms_12102/lib/libnjni12.so(), but a runtime definition of the symbol was not found. rtld: 0712-002 fatal error: exiting.) Exception in thread "main" java.lang.UnsatisfiedLinkError: oracle/net/common/NetGetEnv.get(Ljava/lang/String;)Ljava/lang/String;
Oracle NOTE : 1949184.1
IOCP module not enabled on the server.
To check if the IOCP module is enabled, run the lsdev command:
The following sample output shows the IOCP status is set to Defined and hence not enabled: $ lsdev | grep iocp iocp0 Defined I/O Completion Ports By default, IOCP is set to Defined.
Enable the “iocp” option and relink the oracle binaries.
To enable IOCP, set IOCP to Available using the following procedure:
Log in as root and run the following command: smitty iocp Select Change / Show Characteristics of I/O Completion Ports. Change configured state at system restart from Defined to Available. Run the lsdev command to confirm the IOCP status is set to Available: $ lsdev | grep iocp iocp0 Available I/O Completion Ports Perform a system restart to make the changes permanent. Relink the binaries using " relink all " and then root.sh as root user.
2) 18.104.22.168 Installation fails with error:
PRVG-11322 : One or more node names “host_name” contain one or more of the following invalid characters “_”
As per standards for protocols RFC 952 , host names cannot contain the underscore character (“_”)
The 22.214.171.124 & earlier versions, were able to install on host name with underscore “” , as there was no pre check during the installation for host name with underscore (“”).
Now this is fixed in 126.96.36.199 . And from 188.8.131.52, the CVU checks for host name with underscore “” and the installation will fail, if it finds the host name with underscore “”

The OUI / Installer is detecting the references for earlier installed GI home. Due to the previous failed GI / ASM installation and GI / ASM as it was not removed or cleaned up.
Remove any references for GI Home /u01/app/oracle/product/220.127.116.11/grid.
Delete the files:
/var/tmp/.oracle /etc/oracle/ocr.loc and /etc/oracle/olr.loc files.
