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=trueshell>tpm update
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”
The applier can now be configured.
Unpack the Tungsten Replicator distribution in staging directory:
shell> tar zxf tungsten-replicator-7.1.4-10.tar.gzChange into the staging directory:
shell> cd tungsten-replicator-7.1.4-10
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-7.1.4-10/tungsten-replicator/lib/Configure the installation using tpm:
shell>./tools/tpm configure defaults \ --reset \ --user=tungsten \ --install-directory=/opt/continuent \ --profile-script=~/.bash_profile \ --skip-validation-check=HostsFileCheck \ --skip-validation-check=InstallerMasterSlaveCheck \ --rest-api-admin-user=apiuser \ --rest-api-admin-pass=secretshell>./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

The description of each of the options is shown below; click the icon to hide this detail:
For staging configurations, deletes all pre-existing configuration information between updating with the new configuration values.
System User
--install-directory=/opt/continuent
install-directory=/opt/continuent
Path to the directory where the active deployment will be installed. The configured directory will contain the software, THL and relay log information unless configured otherwise.
--profile-script=~/.bash_profile
profile-script=~/.bash_profile
Append commands to include env.sh in this profile script
--skip-validation-check=HostsFileCheck
skip-validation-check=HostsFileCheck
The --skip-validation-check
disables a given validation check. If any validation check
fails, the installation, validation or configuration will
automatically stop.
Using this option enables you to bypass the specified check, although skipping a check may lead to an invalid or non-working configuration.
You can identify a given check if an error or warning has been raised during configuration. For example, the default table type check:
... ERROR >> centos >> The datasource root@centos:3306 (WITH PASSWORD) » uses MyISAM as the default storage engine (MySQLDefaultTableTypeCheck) ...
The check in this case is
MySQLDefaultTableTypeCheck,
and could be ignored using
--skip-validation-check=MySQLDefaultTableTypeCheck.
Setting both
--skip-validation-check and
--enable-validation-check is
equivalent to explicitly disabling the specified check.
--skip-validation-check=InstallerMasterSlaveCheck
skip-validation-check=InstallerMasterSlaveCheck
The --skip-validation-check
disables a given validation check. If any validation check
fails, the installation, validation or configuration will
automatically stop.

The description of each of the options is shown below; click the icon to hide this detail:
Replication topology for the dataservice.
The hostname of the primary (extractor) within the current service.
Hostnames for the dataservice members
Database type
For databases that required authentication, the username to use when connecting to the database using the corresponding connection method (native, JDBC, etc.).
--replication-password=password
The password to be used when connecting to the database using
the corresponding
--replication-user.
Name of the database to replicate into
Should the replicator service use a batch applier
--batch-load-template=vertica6
Value for the loadBatchTemplate property
Which script language to use for batch loading
The network port used to connect to the database server. The default port used depends on the database being configured.
--svc-applier-filters=dropstatementdata
svc-applier-filters=dropstatementdata
Replication service applier filters
--svc-applier-block-commit-interval=30s
svc-applier-block-commit-interval=30s
Minimum interval between commits
--svc-applier-block-commit-size=25000
svc-applier-block-commit-size=25000
Applier block commit size (min 1)
Disable the use of relay-logs?
If you plan to make full use of the REST API (which is enabled by default) you will need to also configure a username and password for API access. This must be done by specifying the following options in your configuration:
rest-api-admin-user=tungsten rest-api-admin-pass=secret
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.
