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 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.
