Software

Software for 12CR1 is available on OTN or edelivery

• OTN: Oracle Database 12c Release 1 (12.1.0.1) Software (64-bit).
• edelivery: Oracle Database 12c Release 1 (12.1.0.1) Software (64-bit)

Database software

linuxamd64_12c_database_1of2.zip 
linuxamd64_12c_database_2of2.zip

OS configuration and preparation

OS configuration is executed as root. To login as root just execute following command in terminal.

su - root

The “/etc/hosts” file must contain a fully qualified name for the server.

<IP-address>  <fully-qualified-machine-name>  <machine-name>

For example.

127.0.0.1 fedora.dbaora.com fedora localhost.localdomain localhost

Set hostname

hostnamectl set-hostname fedora.dbaora.com --static

Add groups

#groups for database management
/usr/sbin/groupadd -g 501 oinstall
/usr/sbin/groupadd -g 502 dba
/usr/sbin/groupadd -g 503 oper

Add user Oracle for database software

/usr/sbin/useradd -u 501 -g oinstall -G dba,oper oracle

Change password for user Oracle

passwd oracle

Disable secure linux by editing the “/etc/selinux/config” file, making sure the SELINUX flag is set as follows. It requires REBOOT to be effective !!!

SELINUX=disabled

Edit the “/etc/redhat-release” file replacing the current release information “Fedora release 19 (Schrödinger’s Cat)” with the following.

redhat release 6

Packages

Check which packages are installed and which are missing

rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n' binutils \
compat-libstdc++-33 \
gcc \
gcc-c++ \
glibc \
glibc-common \
glibc-devel \
glibc-headers \
ksh \
libaio \
libaio-devel \
libgcc \
libstdc++ \
libstdc++-devel \
libXext \
libXtst \
libX11 \
libXau \
libXi \
make \
sysstat \
unixODBC \
unixODBC-devel \
zlib-devel

Install missing packages. It’s just example:

yum install compat-libstdc++-33 unixODBC unixODBC-devel sysstat

Add kernel parameters to /etc/sysctl.conf

# kernel parameters for 12gR1 installation

fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

Apply kernel parameters

/sbin/sysctl -p

Add following lines to set shell limits for user oracle in file /etc/security/limits.conf

# shell limits for users oracle 12gR1

oracle   soft   nofile   1024
oracle   hard   nofile   65536
oracle   soft   nproc    2047
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768

Additional steps

Create .bash_profile for user oracle

# Oracle Settings
export TMP=/tmp

export ORACLE_HOSTNAME=fedora.dbaora.com
export ORACLE_UNQNAME=ORA12C
export ORACLE_BASE=/ora01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1
export ORACLE_SID=ORA12C

PATH=/usr/sbin:$PATH:$ORACLE_HOME/bin

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;

alias cdob='cd $ORACLE_BASE'
alias cdoh='cd $ORACLE_HOME'
alias tns='cd $ORACLE_HOME/network/admin'
alias envo='env | grep ORACLE'

umask 022

envo

Directory structure

Create directory structure as user root

ORACLE_BASE – /ora01/app/oracle

ORACLE_HOME – /ora01/app/oracle/product/12.1.0/db_1

mkdir -p /ora01/app/oracle/product/12.1.0/db_1
chown oracle:oinstall -R /ora01

In Fedora 19 /tmp data is stored on tmpfs which consumes memory and is too small. To revert it back to storage just run following command and REBOOT machine to be effective.

systemctl mask tmp.mount

Install database software

Let’s start with database software installation as oracle user.

su - oracle

--unizp software it will create directory "database" 
--where you can find installation software
unzip linuxamd64_12c_database_1of2.zip
unzip linuxamd64_12c_database_2of2.zip

--I defined 4 aliases in .bash_profile of user oracle to make 
--administration heaven :)

[oracle@fedora ~]$ alias envo cdob cdoh tns
alias envo='env | grep ORACLE'
alias cdob='cd $ORACLE_BASE'
alias cdoh='cd $ORACLE_HOME'
alias tns='cd $ORACLE_HOME/network/admin'

--run alias command envo to display environment settings
envo
ORACLE_UNQNAME=ORA12C
ORACLE_SID=ORA12C
ORACLE_BASE=/ora01/app/oracle
ORACLE_HOSTNAME=fedora.dbaora.com
ORACLE_HOME=/ora01/app/oracle/product/12.1.0/db_1

--run alias command cdob and cdoh 
--to check ORACLE_BASE, ORACLE_HOME 
[oracle@fedora ~]$ cdob
[oracle@fedora oracle]$ pwd
/ora01/app/oracle

[oracle@fedora db_1]$ cdoh
[oracle@fedora db_1]$ pwd
/ora01/app/oracle/product/12.1.0/db_1

--run installation from "database" directory
./runInstall

1. Uncheck checkbox “I wish to receive security updates via My Oracle Support” and then click “Next” button.

2. Ignore following message and click “Yes” button.

3. Select “Skip software updates” and click “Next” button.

4. Ignore following message. Just click “Yes” button.

5. Select “Create and configure a database” then click “Next” button.

6. Select “Desktop Class” and click “Next” button.

7. On the screen you need to define global database name and pluggable database name. Rest of options you can keep default. Then click “Next” button.

8. Accept default settings then click “Next” button.

9. Summary screen just before installation. It’s the last moment to make changes in previous steps. If you are ready click “Install” button.

10. Installation begins …

11. Unfortunately I received error during binaries linking

in log you should see

/usr/bin/ld: note: '__tls_get_addr@@GLIBC_2.3' is defined in 
DSO /lib64/ld-linux-x86-64.so.2 so try adding it to the linker 
command line /lib64/ld-linux-x86-64.so.2: could not read symbols: 
Invalid operation

INFO: collect2: error: ld returned 1 exit status

12. To solve this problem do following as user Oracle

• remove directory /ora01/app/oracle/product/12.1.0/db_1/lib/stubs

rm -rf /ora01/app/oracle/product/12.1.0/db_1/lib/stubs

• backup file $ORACLE_HOME/rdbms/lib/env_rdbms.mk

cd $ORACLE_HOME/rdbms/lib/
cp env_rdbms.mk env_rdbms.mk.bck

• make changes in $ORACLE_HOME/rdbms/lib/env_rdbms.mk

modify line 176

LINKTTLIBS=$(LLIBCLNTSH) $(ORACLETTLIBS) $(LINKLDLIBS)

to

LINKTTLIBS=$(LLIBCLNTSH) $(ORACLETTLIBS) $(LINKLDLIBS) -lons

modify line 279 and 280

LINK=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS) $(COMPSOBJS)
LINK32=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS32) $(COMPSOBJS)

to

LINK=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS) $(COMPSOBJS) -Wl,--no-as-needed
LINK32=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS32) $(COMPSOBJS) -Wl,--no-as-needed

modify line 3041 and 3042

TG4PWD_LINKLINE= $(LINK) $(OPT) $(TG4PWDMAI) \
        $(LLIBTHREAD) $(LLIBCLNTSH) $(LINKLDLIBS)

to

TG4PWD_LINKLINE= $(LINK) $(OPT) $(TG4PWDMAI) \
        $(LLIBTHREAD) $(LLIBCLNTSH) $(LINKLDLIBS) -lnnz12

Once it’s done click “Retry” button on screen from point 11 to continue with installation. Linking should finish properly and binaries installation should continue.

13. In the end you will be asked to run as root two scripts. Once they are completed click “OK” button – installation will proceed.

/ora01/app/oraInventory/orainstRoot.sh
/ora01/app/oracle/product/11.2.0/db_1/root.sh

18. Once binaries are installed automatically DBCA (database configuration assistant) will start to create new database.

19. You should see summary screen for your database. You can click “Password Management” to unlock and change passwords for default account. Click “OK” button.

20. Installation is finished. Click “Close” button.

21. Post installation steps

Edit the “/etc/redhat-release” file to restore original release information.

Fedora release 19 (Schrödinger’s Cat)

Edit the “/etc/oratab” file to set restart flag for ORA12C to ‘Y’.

ORA12C:/u01/app/oracle/product/12.1.0/db_1:Y

Have a fun 🙂
