Relationship between oracle linux and External Storage Systems

Reference Original:
Oracle Linux and External Storage Systems (Doc ID 753050.1)

Applicability:
Linux OS-Version Oracle Linux 4.4 to Oracle Linux 6.0 with Unbreakable Enterprise Kernel [2.6.32] [Release OL4U4 to OL6]
Linux x86-64
Linux x86
Linux Itanium

Purpose:
This document describes information related to the external storage system in oracle linux configurations.
Note: the list may be incomplete or not up-to-date. For details, refer to the connection provided below

Range:
This document can be used by system engineers and administrators as a reference for creating a new oracle linux system.

Details:

DM-MPIO
DM-MPIO represents Device Mapper Multipathing I/O
Oracle linux and rhel both include DM-MPIO technology, which is developed in close collaboration with various vendors, such as emc.
DM-MPIO has included but limited to the following advantages:

1. User and kernel space tools for management and support
Second, you have more flexibility when upgrading the kernel. Because the DM-MPIO has been accepted by the upstream Linux kernel development team
In other words, the updated driver will be passed to each updated kernel.
On the other hand, if a driver from a third-party manufacturer is used, a new driver package is available in the new kernel version.
Third: Boot-from-SAN support is much easier to setup with DM-MPIO
Fourth: Multipathing support available during installation of OS
Fifth: Hardware vendors are starting to recommend/support DM-MPIO in certain storage deployments

For more information on DM-MPIO and also for varous cases/implementations see

Oracle Validated Configurations
For specific external storage (HP, EMC, NEC, Sun, Compellent, Dell, NetApp, Inspur, Pillar and more) deployments with Oracle Linux please:

Browse to http://linux.oracle.com/validated-configurations
Enter "OEL" in the search box. Click "Go"-that will provide you older validations but still applicable
Enter "Linux" in the search box. Click "Go"
See also the Oracle Technology Network Validated deployments page

Recommended:

First:
Second, run the 'cat/proc/partitions 'and 'dmesg' command to verify the lun.
Third: Use the driver integrated with linux kernel in a possible environment. Do not use a third-party driver.
Fourth: OCFS2 1.2 does not support online filesystem resize.
Use OCFS2 1.4 or later to have resize enabled with OCFS2.
Fifth: for shared file systems between nodes in each cluster, use ocfs2 and gfs instead of nfs.

Relationship between Oracle and Linux

Linux is an operating system, just like windows, which we usually use.
Oracle is a database. You can understand it as an application.

Oracle can be installed on linux or windows.

How to view the oracle stored procedures in linux?

Run the ls command.
It may be in the following two paths.
/Home/oracle/
/Etc/
