Oracle ACFS Support on Linux detailed solution

recently ready to use Oracle ACFS built ogg-ha in a RAC environment, so a set of Oracle11.2.0.4.0 RAC was built on the RedHat6.5 system, found that ACFS cannot be used. After looking for a lot of data, found that 11G ACFS does not support RedHat6.5,11.2.0.4.0 only support to RedHat6.3. Next , let's look at the information about ORACLEACFS support on Linux.

not supported description of the ACFS

acfs OS kernel There is no on the module ACFS related information. Next we look at cluster service ACFS related services

Acfsdriverstate is a shell script, by calling $ORACLE _home/lib/acfstoolsdriver.sh script, followed by Acfstoolsdriver.sh call $ORACLE _home/lib/osds-*.pm< Span style= "Font-family:simsun, serif;" > script for validation. where osds-acfslib.pm Perl Osplatforms and the corresponding version. Let's take a look at this script (because I have a perl

# testing for  "Oraclelinux_release",  etcprevents  us from dropping# into the code below from other RH  based distroslike centos, for example.if  ((defined ($release))  &&                 #Redhat  or oel  if defined      ($release  =~ /^redhat-release/)  | |      # straight RH       ($release  =~  /^enterprise-release/)  | |    # Oracle Enterprise Linux       ($release  = ~ /^oraclelinux-release/))     # oracle linux 

redhat centos,oracle linux redhat The os ACFS and then there's the great God. This adds the script to the The support for Centos

See if there are any friends here, try to modify the OSDS-ACFSLIB.PM support kernel version of the relevant information? Right, the author tried, but for the author of this rookie, it must have ended in failure. Further analysis of the cause of the failure is followed:

you then confirm that the OS supports ACFS by command Uname–r (RedHat 6),uname–r–i (REDHAT5).

For the above summary:

1, If you need to use ACFS , the first plan to choose the function of the OS, avoid reloading, can use CentOS, but the kernel version must meet the support ACFS kernel.

2, You can also use UEK (unbreakableenterprise Kernel) to replace the core.

3. to use ACFS, the compatibility of ASM needs to be set to 11.2(alterdiskgroup Data set attribute ' COMPATIBLE. ASM ' = ' 11.2 '; )
