Step by Step Oracle 12c Database Installation on Linux

July 30, 2016 by techgoeasy Leave a Comment

I will be posting the step by step Oracle 12c Database Installation on Linux. First we will performing the binaries installation and then creating the database using DBCA

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.

/u50/app/oracle/software/database/runInstaller

Once the GUI starts, respond as follows:

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/12.1.0.2/root.sh

/u50/app/oracle/product/12.1.0.2/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/12.1.0.2

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

./dbca

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/12.1.0.2
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/12.1.0.2)
(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)
)
)

4) How to Login to 12c database

$ sqlplus / as sysdba

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

CAUSE

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.

SOLUTION

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) 12.1.0.2 Installation fails with error:

PRVG-11322 : One or more node names “host_name” contain one or more of the following invalid characters “_”

Cause

As per standards for protocols RFC 952 , host names cannot contain the underscore character (“_”)

Solution

The 12.1.0.1 & 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 12.1.0.2 . And from 12.1.0.2, the CVU checks for host name with underscore “” and the installation will fail, if it finds the host name with underscore “”
3) Oracle 12c Installation fails with PRCI-1113 PRVF-5300 PRKC-1032

While performing the 12c standalone installation, the installer is failing with below error:

ERRORMSG(localhost): PRCI-1113 : Directory /u01/app/oracle/product/12.1.0.2/grid does not exist

ERRORMSG(localhost): PRCI-1113 : Directory /u01/app/oracle/product/12.1.0.2/grid does not exist

INFO: Advice is ABORT
SEVERE: Unconditional Exit
INFO: Adding ExitStatus FAILURE to the exit status set

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.

Solution

Remove any references for GI Home /u01/app/oracle/product/12.1.0.2/grid.
Delete the files:

/var/tmp/.oracle
/etc/oracle/ocr.loc and /etc/oracle/olr.loc files.
