Generic SharePlex demonstration-all platforms

Contents

 

  • This chapter demonstrates the basics of SharePlex replication. This demonstration can be run on Unix or Linux for any of the supported SharePlex source and 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 SharePlex replicates an Oracle TRUNCATE command
    • How SharePlex verifies synchronization and repairs out-of-sync rows
    • 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

    Create and activate a configuration

    SharePlex gets its replication instructions from a configuration file, which defines the objects that are to be replicated. The file specifies following:

    • The datasource (source database) — the identifier of the source database.
    • The source objects — the names of the objects that contain the data to be replicated.
    • The target objects — the names of the target objects that will receive the replicated data.
    • The routing map — the name of the target system and, if the target is a database, its identifier.

    Note: This demonstration demonstrates replication from one database to another. It does not cover replication to a file or a messaging container.

    Create a configuration file

    Perform these steps on the source system. The demonstration objects are assumed to be in the schema named splex.

    Perform the following steps to create a configuration file:

    1. Run sp_ctrl.

    2. Issue the following command to create a configuration file named sample_config in the default text editor.

      sp_ctrl(source)> create config sample_config

    3. In the text editor, build your configuration file based on the appropriate template, as shown in the Configuration templates. Allow no spaces between the characters in a component (source specification, target specification, routing map), and place at least one space between each component.

    4. Save the file, then exit the editor. SharePlex automatically saves the file in the config sub-directory of the variable-data directory.
    5. In sp_ctrl, verify that the configuration file will activate successfully.

      sp_ctrl(source)>verify config sample_config

    Configuration templates

    Oracle source to Oracle target

    datasource:o.source_SID

    splex.demo_src

    splex.demo_dest

    target_system@o.target_SID

    where:

    • source_SID is the ORACLE_SID of the source database.
    • target_system is the name or IP address of the target system.
    • target_SID is the ORACLE_SID of the target database.
    Oracle source to Open Target

    datasource:o.source_SID

    splex.demo_src

    splex.demo_dest

    target_system@r.database_name

    where:

    • source_SID is the ORACLE_SID of the source database.
    • target_system is the name or IP address of the target system.
    • database_name is the name of the Open Target database.
    PostgreSQL source to PostgreSQL target

    datasource:r.source_DB

    "qarun"."basic_c127"

    "splex"."basic_c127"

    10.250.14.105@r.sp_ad

    where:

    • source_DB is the database name of the source database
    • "qarun" is the database user of the source database
    • "splex" is the database user of the target database
    • "sp_ad" is the database name of the source database

    Activate the configuration

    Perform these steps on the source system. When you activate a configuration, SharePlex is ready to capture transactional changes that are made to the specified source data.

    Perform the following steps to activate a configuration file:

    1. Activate the configuration.

      sp_ctrl(source)> activate config sample_config

      Note: Configuration names are case-sensitive.

    2. Confirm that the configuration activated successfully. The name sample_config should appear under File Name, and the word Active should appear under State.

      sp_ctrl(source)> list config

    Troubleshooting tips

    If your configuration activation fails, isue the view config sample_config command to view the file. Compare it to the template and make sure all of the information you entered is correct. Make certain you specified the correct database identifier. Check your syntax for extra spaces or missing components.

    Because the configuration file is not active, you can edit it directly with the following command:

    sp_ctrl(source)> edit config sample_config

    Save the changes, then re-try the activation.

    Note: To change an active configuration, you must copy it to a new file first, and then edit and activate the copy. For more information, see Add or Change Table Specifications in an Active Configuration in the SharePlex Installation and Setup Guide.
