CREATING AND USING ADDITIONAL SWAP SPACE

If you don’t have any additional disks, you can create a file somewhere on your filesystem, and

use that file for swap space.The following dd command example creates a swap file with the name “myswapfile” under /root

directory with a size of 1024MB (1GB).

# dd if=/dev/zero of=/root/myswapfile bs=1M count=1024

1024+0 records in

1024+0 records out

# ls -l /root/myswapfile

-rw-r--r-- 1 root root 1073741824 Aug 14 23:47 /root/myswapfile

Change the permission of the swap file so that only root can access it.

# chmod 600 /root/myswapfile

Make this file as a swap file using mkswap command.

# mkswap /root/myswapfile

Setting up swapspace version 1, size = 1073737 kB

Enable the newly created swapfile.

# swapon /root/myswapfile

To make this swap file available as a swap area even after the reboot, add the following line to

the /etc/fstab file.

# vi /etc/fstab

/root/myswapfile swap swap defaults

0 0




Verify whether the newly created swap area is available for your use.

# swapon -s

Note: In the output of swapon -s command, the Type column will say “file” if the swap space is

created from a swap file.

TO SOLVE THE ERROR OS Kernel Parameter: semopm

The semop system call (function) provides the ability to do operations for multiple semaphores

with one semop system call. A semaphore set can have the maximum number of SEMMSL

semaphores per semaphore set and is therefore recommended to set SEMOPM equal to SEMMSL.

Oracle recommends setting the SEMOPM to a value of no less than 100. When you need to

change the semopm value you can do the following:

echo "kernel.sem=250 32000 100 128" >> /etc/sysctl.conf

sysctl -p /etc/sysctl.conf

This should solve this issue and you should be able to install the database.

TO SOLVE THE ERROR OS Kernel Parameter: file-max

OS Kernel Parameter: file-max

This is a prerequisite condition to test whether the OS kernel parameter "file-max" is

properly set.

Expected Value

: 6815744 Actual Value

: 198903

Stating that the file-max kernel setting should read 6815744. The solution to this is to edit the

file /etc/sysctl.conf and add the (or change a existing line to) line to the following:

fs.file-max = 6815744




After you have done so you will have to activate the new file-max setting. One can do so by a

reboot or you can do it on the fly by executing the following command:


This should have resolved your issue. You can check it by executing the oracle database installeror you can directly check from the command line by executing the following command:

cat /proc/sys/fs/file-max

The result of this should now list 6815744

TO SOLVE THE ERROR OS Kernel Parameter: IP-LOCAL-PORT-RANGE

OS Kernel parameter: ip_local_port_range

This is a prerequisite condition to test whether the OS kernel parameter

"ip_local_port_range" is properly set.

Expected Value : between 9000 & 65500

Actual Value : between 32768 & 61000

The /proc/sys/net/ipv4/ip_local_port_range defines the local port range that is used by TCP and

UDP traffic to choose the local port. You will see in the parameters of this file two numbers: The

first number is the first local port allowed for TCP and UDP traffic on the server, the second is the

last local port number. For high-usage systems you may change its default parameters to 32768-

61000 -first-last.

echo "net.ipv4.ip_local_port_range = 9000 65500" >> /etc/sysctl.conf


This should solve your problem and you should be able to install the Oracle database on your

system.

Yes, the keys in the /etc/sysctl.conf file are incorrect. Modify

your entries to read:

net.core.rmem_default = 262144

net.core.rmem_max = 262144

net.core.wmem_default = 262144

net.core.wmem_max = 262144

TO CHECK sysctl -p /etc/sysctl.conf




TO SOLVE THE ERROR OS Kernel Parameter: aio-max-nr

This is a prerequisite condition to test whether the OS kernel parameter "aio-max-nr"

is properly set.

Expected Value : 1048576

Actual Value : 65536

The /proc/sys/fs/aio-max-nr file is the maximum number of allowable concurrent requests. The

maximum is commonly 64KB, which is adequate for most applications. This is related to

asynchronous I/O usage on your system. IBM is running a great article on this which you can

find here at the IBM website where they dive into the POSIX AIO API.

To solve the problem in hand you have to add the below line to your /etc/sysctl.conf file.

fs.aio-max-nr = 1048576

After you have done so you can activate your settings by executing the following command:


When this is done you should be set and ready to continue the installation of your database.

AFTER INSTALLING ORACLE 11G TO CHECK

#hostname :- to find the host name of the server

# su - oracle :- switch to oracle user

$cd /u01/app/oracle/

$ls

$cd product/11.2.0/db_1/

$ls

$sqlplus

(if we get shared library error go to se linux doc and find error log and

execute it

login to root user and ececute

#chcon -t textrel_shlib_t

'/u01/app/oracle/product/11.2.0/db_1/lib/libclntsh.so.11.1'




ORA-12162 TNS:net service name is incorrectly

specified

Oracle Tips by Burleson Consulting

The error message ORA-12162 "TNS:net service name is incorrectly specified" , is verymisleading. It suggests that there is a problem with the tnsnames.ora file contents, but in reality the messageORA-12162 "TNS:net service name is incorrectly specified" results from improperly setting your ORACLE_SID value. To fix this error in Windows, set your $ORACLE_HOME: c:> set ORACLE_SID=fred In Linux, these commands sets ORACLE_HOME and $ORACLE_SID as follows:

$ export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1

$ export ORACLE_SID=orcl

how to find ORACLE_SIDA few ways would be the following.

UNIX/LINUX:

echo $ORACLE_SID

If this doesn't show anything, you can check the /var/opt/oracle/oratab file on UNIX and the

/etc/oratab file on LINUX.

Windows:

echo %ORACLE_SID%

If this doesn't show anything, you can check the window's service for a service named

OracleSerivce<sid_name>.
