On the new host, ensure the Appendix B, Prerequisites have been followed.

Update the configuration using tpm, adding the new host to the list of connectors

If using the staging method of deployment, you can use +=, which appends the host to the existing deployment as shown in the example below. Click the link to switch between staging and ini type deployment examples.

Show Staging

Show INI

shell> tpm query staging
tungsten@db1:/opt/continuent/software/tungsten-clustering-6.1.25-6

shell> echo The staging USER is `tpm query staging| cut -d: -f1 | cut -d@ -f1`
The staging USER is tungsten

shell> echo The staging HOST is `tpm query staging| cut -d: -f1 | cut -d@ -f2`
The staging HOST is db1

shell> echo The staging DIRECTORY is `tpm query staging| cut -d: -f2`
The staging DIRECTORY is /opt/continuent/software/tungsten-clustering-6.1.25-6

shell> ssh {STAGING_USER}@{STAGING_HOST}
shell> cd {STAGING_DIRECTORY}

shell> ./tools/tpm configure alpha \
    --connectors+=host4 \

Run the tpm command to update the software with the Staging-based configuration:

shell> ./tools/tpm update --no-connectors

For information about making updates when using a Staging-method deployment, please see Section 10.3.7, “Configuration Changes from a Staging Directory”.

shell> vi /etc/tungsten/tungsten.ini

[alpha]
...
connectors=host4

Run the tpm command to update the software with the INI-based configuration:

shell> tpm query staging
tungsten@db1:/opt/continuent/software/tungsten-clustering-6.1.25-6

shell> echo The staging DIRECTORY is `tpm query staging| cut -d: -f2`
The staging DIRECTORY is /opt/continuent/software/tungsten-clustering-6.1.25-6

shell> cd {STAGING_DIRECTORY}

shell> ./tools/tpm update --no-connectors

For information about making updates when using an INI file, please see Section 10.4.4, “Configuration Changes with an INI file”.

Using the --no-connectors option updates the current deployment without restarting the existing connectors.

During a period when it is safe to restart the connectors:

shell> ./tools/tpm promote-connector
