Install SharePlex on PostgreSQL High Availability Cluster

SharePlex supports CrunchyData High Availability cluster environment setup.

Follow the below configuration steps:

  1. Setup the CrunchyData High Availability cluster environment according to the CrunchyData setup documentation.

  2. Install or upgrade to SharePlex 11.1.

  3. Run the pg_setup utility and enter a slot name.

  4. Activate the configuration. The user input slot name will be created in the database after a successful activation.

  5. Add the slot name to the respective CrunchyData config [YML or YAML] file to monitor in failover or switchover scenario.

  6. Run the deactivate configuration or cleanup [pg_cleansp] utility to remove the dedicated slot name from the database. Users need to remove SharePlex dedicated slot name from the CrunchyData config file.

  7. Remove the SharePlex dedicated slot name from the CrunchyData config file.

Example of CrunchyData config command: patronictl -c /etc/patroni/crunchy-demo.yml edit-config

NOTE: User need to add SharePlex dedicated slot name to the respective CrunchyData config.

Limitation: SharePlex internally uses PostgreSQL logical replication with a PostgreSQL database over cloud services. In the event of a failover to the standby server, the logical replication slots are not copied over to the standby server on cloud database services; hence, SharePlex will not handle logical slot re-creation and maintenance with cloud database services. This applies to the Azure PostgreSQL Flexi server, the AWS Multi-AZ cluster setup of the RDS PostgreSQL, and the Aurora PostgreSQL databases.

Generic SharePlex Demonstration for PostgreSQL

Contents

 

  • This chapter demonstrates the basics of SharePlex replication. This demonstration can be run on Unix or Linux from a PostgreSQL source to supported target databases.

    Notes:

    • These demonstrations are for use with databases. They do not support replication to a file or a messaging container.
    • These are only demonstrations. Do not use them as the basis for deployment in a production environment. To properly implement replication in your environment, follow the instructions in the SharePlex Installation and Setup Guide and the SharePlex Administration Guide.
    • For more information about the commands used in the demonstrations, see the SharePlex Reference Guide.
    • The demonstrations assume that SharePlex is fully installed on a source system and one target system, and that any pre- and post-installation setup steps were performed.

    What you will learn

    • How to activate a configuration
    • How SharePlex replicates smoothly from source to target systems
    • How SharePlex quickly and accurately replicates large transactions
    • How SharePlex queues the data if the target system is unavailable
    • How SharePlex resumes from its stopping point when the target system is recovered
    • How SharePlex recovers after a primary instance interruption
    • How to use named queues to spread the processing of different tables across parallel Post processes

    • Prework for the demonstrations

    Before you run the basic demonstrations, have the following items available.

    Tables used in the demonstrations

    You will replicate splex.demo_src from the source system to splex.demo_dest on the target system. These tables are installed by default into the SharePlex schema, which in these demonstrations is "splex." Your SharePlex schema may be different. Verify that these tables exist.

    Description of the demo tables.
    Column Name Data Type Null?
    NAME varchar2(30)  
    ADDRESS verchar2(60)  
    PHONE varchar2(12)

     

    INSERT scripts

    • Create a SQL script named insert_demo_src that inserts and commits 500 rows into the splex.demo_src table. You will run this script during some of the demonstrations.
    • If you will be using the demonstration of named post queues, create a SQL script named insert_demo_dest that inserts and commits 500 rows into the splex.demo_dest table. You will run this script during some of the demonstrations.

    Start SharePlex

    Start SharePlex

    The following are instructions for starting SharePlex and the sp_ctrl command-line interface on Unix and Linux. Start SharePlex on the source and target systems.

    To start SharePlex on Unix and Linux systems:

    1. Log onto the system as a SharePlex Administrator (a member of the SharePlex Admin group).

    2. From the bin sub-directory of the SharePlex product directory ( productdir in the following syntax), run sp_cop and sp_ctrl.

      $cd /productdir/bin

      $./sp_cop &

      $. /sp_ctrl
