  • Exadata: Install Oracle GoldenGate 12c using ACFS File System

    Overview
    You can install Oracle GoldenGate for Oracle RAC using:

    • Shared Storage
      •  NFS, OCFS2, DBFS, OCFS
    • Local file system
    You can Install Oracle GoldenGate 12c in 2 ways:

    • Graphical User Interface (GUI)
    • Using response file (Silent)

    In this article I will demonstrate how to Install Oracle GoldenGate 12c using GUI on a full Rack Exadata Database Machine using ACFS file system.

    What is ACFS?
    Automatic Storage Management Cluster File System (ACFS) was introduced in Oracle database 11gR2. ACFS is a general purpose single-node or cluster file system on top of ASM. ACFS can be accessed using industry-standard Network Attached Storage (NAS) file access protocols: Network File System (NFS) and Common Internet File System (CIFS)

    Installing GoldenGate on ACFS
    ACFS file systems are mounted on all nodes in a cluster. Oracle GoldenGate is supported in an Oracle ACFS environment. GoldenGate should be installed in the cluster to capture the data from the database.

    How to configure ACFS?
    Take a look at the below 2 articles on how to configure ACFS on Exadata Database Machine.
     

    Flex ASM: http://netsoftmate.blogspot.in/2017/03/configure-acfs-on-exadata-running.html
    Standard ASM: http://netsoftmate.blogspot.in/2017/02/configure-acfs-on-exadata-database.html

    Environment:

    • Exadata Database Machine X5-2 Full Rack
    • Oracle GoldenGate 12.2.0.1
    • Oracle Database 12.2.0.1
    • ASM Cluster File System (ACFS)
    Verify ACFS is running and mounted

    • Open the .bash_profile and add the following two variables
    dm01db01-orcldb1 {/home/oracle}: vi .bash_profile

    export GG_HOME=/acfs_ogg/app/oracle/product/12.2.0.1/gghome
    export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/lib32:$GG_HOME

    *** Repeat the above step on all the nodes to update the .bash_profile***

    • Execute the .bash_profile and verify the variables.

    Conclusion
    This completes our Oracle GoldenGate 12c installation on Exadata database machine using ACFS. We have seen how much easy it is to install Oracle GoldenGate software using GUI interface. The key for installing Oracle GoldenGate on 12c a RAC environment is to choose a shared location for software. You can also choose to install Oracle GoldenGate on local file system if you don’t have a shared location.
