Change hostname of your Linux server

Leave a comment

Oracle RAC depends heavily on the network, hostnames, and DNS service within a network. In this article we will show how to change the hostname of a LINUX server for the use of Oracle RAC to include the domain name.
1. Logon to your LINUX server as the root user.
2. Open the file /etc/sysconfig/network.
3. Update the parameter HOSTNAME to include the domain name.
[root@mylinux1 ~]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=mylinux1.mydomain.com

[root@mylinux1 ~]#

4. Reboot the server.
5. Issue the command hostname and you will see it is updated.
[root@mylinux1 ~]# hostname
mylinux1.mydomain.com
[root@mylinux1 ~]#

This completes changing the hostname of a LINUX server for Oracle RAC.

Oracle Installation – Add swap space in UNIX or Linux environment

Leave a comment

The typical Oracle installation will require more swap space on a system, due to prerequisite checks performed by the installer, than is typical available. The following procedure shows how to create additional swap in Unix or Linux.

1. Create a file on /u01 of 12gb with the dd command. NOTE: Repeat on each RAC node.

dd if=/dev/zero of=/u01/tempswap bs=1k count=12000000

Example:

[root@mylinux1 ~]# dd if=/dev/zero of=/u01/tempswap bs=1k count=12000000
12000000+0 records in
12000000+0 records out
12384000000 bytes (12 GB) copied, 64.2111 seconds, 255 MB/s
[root@mylinux1 ~]#

2. Then format your new file with the mke2fs command. NOTE: Repeat on each RAC node.

/sbin/mke2fs /u01/tempswap

Example:

[root@mylinux1 ~]# /sbin/mke2fs /u01/tempswap
mke2fs 1.39 (29-May-2006)
/u01/tempswap is not a block special device.
Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
2003424 inodes, 4000000 blocks
200000 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4097835008
123 block groups
32768 blocks per group, 32768 fragments per group
12288 inodes per group
Superblock backups stored on blocks:
32768, 98304, 123840, 229376, 294912, 819200, 884736, 1205632, 2654208

Writing inode tables: done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 29 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
[root@mylinux1 ~]#

3. Make the additional swap space with the mkswap command. NOTE: Repeat on each RAC node.

/sbin/mkswap /u01/tempswap

Example:

[root@mylinux1 ~]# /sbin/mkswap /u01/tempswap
Setting up swapspace version 1, size = 12383995 kB
[root@mylinux1 ~]#

4. Make the swap space available to the OS with the command swapon. NOTE: This will have to be executed after every reboot. Repeat on each RAC node.

/sbin/swapon /u01/tempswap

Example:

[root@mylinux1 ~]# /sbin/swapon /u01/tempswap
[root@mylinux1 ~]#

Oracle Installation files extraction with PAX

Leave a comment

For a Unix or Linux installation, Oracle places its installation files in cpio (archiving format) to contain multiple directory structures in a single file. This article describes the use of the pax utility to extract Oracle installation files.

1. Download your oracle installation files from www.oracle.com

2. Logon to your Oracle database server and place the installation files in the appropriate location.

3. Extract the cpio.gz installation files with the pax utility and options -rvzf

pax -rvzf (name_of_cpio_file.cpio.gz)

4. If the cpio archive file is not compressed, use the pax utility and options –rvf.

pax -rvf (name_of_cpio_file.cpio)

5. This completes unpacking of Oracle installation files with the utility pax.

Oracle Installation files extraction with cpio

Leave a comment

For a Unix or Linux installation, Oracle places its installation files in cpio (archiving format) to contain multiple directory structures in a single file. This article describes the use of the cpio utility to extract Oracle installation files.

1. Download your oracle installation files from www.oracle.com

2. Logon to your Oracle database server and place the installation files in the appropriate location.

3. Extract the cpio.gz installation software with the following command.

gunzip (name_of_cpio_file .cpio.gz)

4. Unpack the archive file using the cpio utility with options –idmv

cpio -idmv < (name_of_cpio_file.cpio)
NOTE: replace the string (name_of_cpio_file .cpio) with your actual cpio file name, but do not remove the first < - greater than sign, that is the input of your file name into the utility. 5. This completes unpacking of Oracle installation files with the utility cpio. Larry J. Catt, OCP 9i, 10g oracle@allcompute.com www.allcompute.com

Oracle error OUI-10058

Leave a comment

The OUI (Oracle Universal Installer) relies on an Oracle inventory to recognize the Oracle software which already exists on the system. Multiple files are read during the OUI startup, the first of which is /etc/oraInst.loc. The oraInst.loc file points to the location of the Oracle inventor directory, which could be anywhere. In order to get an inventory of the current system, OUI must have access to this file. The error OUI-10058 is an indication that OUI does not have access to this file. This article covers the typical error and resolution to this problem

Typical error:

OUI-10058 The OUI Inventory on this system does not exist or is not writable.
1. The /opt/oracle/oraInventory/orainstall…..
or
2. You are not a member of the specified installer group.


Solution: If you executed all previous root.sh script as instructed, the most like cause is permission.

1. Logon to the system as root.
2. Change directory to /etc
3. Check the file permissions with the command ll

[root@mylinux /]# ll *ora*

4. If the file permission is not set to 644, change the permissions with the command chmod

[root@mylinux /]# chmod 644 /etc/oraInst.loc.

5. This completes the resolution of OUI-10058, due to file permissions of /etc/oraInst.loc.

Oracle installation of 10.2.0.4 for Windows 7 Error

Leave a comment

While I am not an OS expert, I can comment that Windows 7 has given us speed and reliability while eliminating the sluggish performance and over-bearing protection of Vista. In this series, I would like to discuss problems one may encounter while running Oracle products on a Windows 7 client and ways in which these problems can be over come. This article discusses the Error of incorrect operating system found while installing Oracle 10.2.0.4 on a Windows 7 machine and how to ignore this error.

1. After you have downloaded the 10204_vista_w2k8_x64_production_db software from Oracle website and attemtpted to install the software with the command setup, you will probably encounter the below error.

Starting Oracle Universal Installer…

Checking installer requirements…

Checking operating system version: must be 5.0, 5.1, 5.2 or 6.0 . Actual 6.1

Failed < <<< Exiting Oracle Universal Installer, log for this session can be found at C:\User s\Home\AppData\Local\Temp\OraInstall2010-08-03_11-57-13AM\installActions2010-08- 03_11-57-13AM.log Please press Enter to exit...

2. This type of error is typical for most software once a new operating system version is released. To bypass the error, first open a command prompt by entering: Start –> Run –> CMD and enter.

3. Navigate the to directory of your oracle installer.

C:\Users\Home>
C:\Users\Home>cd c:\software\10204_vista_w2k8_x64_production_db\database

c:\software\10204_vista_w2k8_x64_production_db\database>

4. Now execute the command: setup.exe -ignoresysprereqs

c:\software\10204_vista_w2k8_x64_production_db\database>setup.exe -ignoresysprereqs

5. If a warning screen appears, click Yes to install the software.

6. At the Welcome Screen, you can press Next to begin your installation.

That completes the installation of Oracle 10.2.0.4 RDBMS on a Window 7 machine.
