This article introduces the knowledge of "what is the step of enabling Oracle ACFS under CentOS". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

By default, CentOS is not one of the operating systems officially supported by Oracle. The ACFS feature is also not installed when you install Grid. When you try to install, you will prompt "Not Supported"

The kernel that installs Oracle Enterprise Linux uploads an ISO file of OEL 7.3.Using ISO as a local yum source installation

Yum-config-manager-disable ol7*

Yum-config-manager-enable ol7_UEKR3

Sed-I's Universe DFAULTKERNELL kernelash DFAULTERNERNELL kernelash / etc/sysconfig/kernel

Yum install kernel-uek kernel-uek-devel

After installation:

Grub2-editenv list

Init 6

Make GRID software patch

Patch: 25078431

1. Replace the opatch tool

P6880880_180000_Linux-x86-64.zip

The opatch of all nodes here needs to be replaced.

two。 Decompress and replenish the bag

Unzip / u01/p25078431_122010_Linux-x86-64.zip-d / tmp

3. Make a patch

/ u01/app/12.2.0/grid/OPatch/opatchauto apply / tmp/25078431

Both nodes have to be hit.

4. Modify Oracle configuration file

Modify $GRID_HOME/lib/osds_acfslib.pm

Reference:

Https://blog.csdn.net/weiwangsisoftstone/article/details/78813518

[root@rac01 lib] # vi osds_acfslib.pm

# Testing for "oraclelinux_release", etc prevents us from dropping

# into the code below from other RH based distros like CentOS, for example.

If ((defined ($release)) & & # Redhat or OEL if defined

(($release = ~ / ^ redhat-release/) | | # straight RH

($release = ~ / ^ enterprise-release/) | | # Oracle Enterprise Linux

($release = ~ / ^ centos-release/) | | # CentOS hack

($release = ~ / ^ oraclelinux-release/) # Oracle Linux
