4.3.2. Install Vertica Applier

  1. Before installing the applier, the following additions need adding to the extractor configuration. Apply the following parameter to the extractor configuration before installing the applier

    Add the following the /etc/tungsten/tungsten.ini

    [alpha]
    ...Existing Replicator Config...
    enable-heterogeneous-service=true
    
    shell> tpm update

    Note

    The above step is only applicable for standalone extractors. If you are configuring replications from an existing Tungsten Cluster (Cluster-Extractor), follow the steps outlined here to ensure the cluster is configured correctly: Section 3.4.1, “Prepare: Replicating Data Out of a Cluster”

  2. The applier can now be configured.

    Unpack the Tungsten Replicator distribution in staging directory:

    shell> tar zxf tungsten-replicator-6.1.5-20.tar.gz
  3. Change into the staging directory:

    shell> cd tungsten-replicator-6.1.5-20
  4. Locate the Vertica JDBC driver. This can be downloaded separately from the Vertica website. The driver will need to be copied into the Tungsten Replicator lib directory.

    shell> cp vertica-jdbc-7.1.2-0.jar tungsten-replicator-6.1.5-20/tungsten-replicator/lib/
  5. Configure the installation using tpm:

    Show Staging

    Show INI

    shell> ./tools/tpm configure defaults \
        --reset \
        --user=tungsten \
        --install-directory=/opt/continuent \
        --profile-script=~/.bash_profile \
        --skip-validation-check=HostsFileCheck \
        --skip-validation-check=InstallerMasterSlaveCheck
    
    shell> ./tools/tpm configure alpha \
        --topology=master-slave \
        --master=sourcehost \
        --members=localhost \
        --datasource-type=vertica \
        --replication-user=dbadmin \
        --replication-password=password \
        --vertica-dbname=dev \
        --batch-enabled=true \
        --batch-load-template=vertica6 \
        --batch-load-language=js \
        --replication-port=5433 \
        --svc-applier-filters=dropstatementdata \
        --svc-applier-block-commit-interval=30s \
        --svc-applier-block-commit-size=25000 \
        --disable-relay-logs=true
    
    shell> vi /etc/tungsten/tungsten.ini
    [defaults]
    user=tungsten
    install-directory=/opt/continuent
    profile-script=~/.bash_profile
    skip-validation-check=HostsFileCheck
    skip-validation-check=InstallerMasterSlaveCheck
    
    [alpha]
    topology=master-slave
    master=sourcehost
    members=localhost
    datasource-type=vertica
    replication-user=dbadmin
    replication-password=password
    vertica-dbname=dev
    batch-enabled=true
    batch-load-template=vertica6
    batch-load-language=js
    replication-port=5433
    svc-applier-filters=dropstatementdata
    svc-applier-block-commit-interval=30s
    svc-applier-block-commit-size=25000
    disable-relay-logs=true

  6. Once the prerequisites and configuring of the installation has been completed, the software can be installed:

    shell> ./tools/tpm install

If you encounter problems during the installation, check the output of the /tmp/tungsten-configure.log file for more information about the root cause.

Once the service is configured and running, the service can be monitored as normal using the trepctl command. See Section 4.3.3, “Management and Monitoring of Vertica Deployments” for more information.
