Configure the Oracle ACFS Cluster File System

First of all, Shenma is ACFS. Please refer to the definition officially provided by Oracle:
Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is a multi-platform, scalable file system, and storage management technology that extends Oracle Automatic Storage Management (Oracle ASM) functionality to support customer files maintained outside of Oracle Database. oracle ACFS supports databases and application files, including executables, database trace files, database alert logs, application reports, BFILEs, and configuration files. other supported files are video, audio, text, images, engineering drawings, and other general-purpose application file data.

ACFS is a Scalable Cluster File system that supports multiple platforms. It can be used to store files of databases and applications, including trace files of databases, alert Log Files and configuration files can also be used to store video, audio, text, images, and other files!

Before that, the cluster file system used the RedHat gfs and the open-source ocfs2. gfs felt that the configuration was too cumbersome and complex because it was based on the RHCS suite, therefore, many functions correspond to the simple cluster file system, which seems to be somewhat redundant. ocfs2 is a abandoned child and has stopped development, but it is easier to configure it; ACFS was launched in 11g r2. It is easy to configure Based on grid infrastructure and developed based on ASM. The stability should be ensured, next, we plan to use ACFS to test the golden gate replication in the rac environment! The following describes the use of ACFS in the 11g rac environment!

1. Check whether acfs-related services are normal.

 
 

  
  
[grid@rac1 ~]$ crs_stat -t -v ora.registry.acfs  
  
  
Name           Type           R/RA   F/FT   Target    State     Host

Ii. Use the asmca graphical tool to create a volume in the asm disk and format it into an ACFS file system.

1. [Root @ rac1 ~] # Su-grid
2. [Grid @ rac1 ~] $! Exp
3. ExportDISPLAY=192. 168.1.105: 0
4. [Grid @ rac1 ~] $ Asmca
