The tpm query command provides information about the current tpm installation. There are a number of subcommands to query specific information:
tpm query config — return the full configuration values
tpm query dataservices — return the list of dataservices
tpm query default — return the list of configured default values
tpm query deployments — return the configuration of all deployed hosts
tpm query modified-files — return the list of files modified since installation by tpm
tpm query staging — return the staging directory from where Tungsten Cluster was installed
tpm query topology — return the current topology
tpm query usermap — return the list of users
organized by type from the user.map
tpm query values — return the list of configured values
tpm query version — get the version of the current installation
Returns a list of all of the configuration values, both user-specified and implied within the current configuration. The information is returned in the form of a JSON value:
shell> tpm query config
{
"__system_defaults_will_be_overwritten__": {
...
"staging_directory": "/home/tungsten/tungsten-clustering-6.1.25-6",
"staging_host": "tr-ms1",
"staging_user": "tungsten"
}Returns the list of configured dataservices that have, or will be, installed:
shell> tpm query dataservices
alpha : PHYSICALReturns a list of all the individual deployment hosts and configuration information, returned in the form of a JSON object for each installation host:
shell> tpm query deployments
{
"config_target_basename": "tungsten-clustering-6.1.25-6_pid22729",
"dataservice_host_options": {
"alpha": {
"start": "true"
}
...
"staging_directory": "/home/tungsten/tungsten-clustering-6.1.25-6",
"staging_host": "tr-ms1",
"staging_user": "tungsten"
}
Shows the list of configuration files that have been modified since the
installation was completed. Modified configuration files cannot be
overwritten during an upgrade process, using this command enables you
identify which files contain changes so that these modifications can be
manually migrated to the new installation. To restore or replace files
with their original installation, copy the
.filename.orig file.
Returns the host and directory from which the current installation was created:
shell> tpm query staging
tungsten@host1:/home/tungsten/tungsten-clustering-6.1.25-6This can be useful when the installation host and directory from which the original configuration was made need to be updated or modified.
For convenience, the following command will take you straight to the directory:
shell> cd `tpm query staging | cut -d: -f2`Returns the current topology and list of configured servers and roles in the form of a JSON object:
shell> tpm query topology
{
"host1": "slave",
"host2": "slave",
"host3": "master"
}
Returns a summarized list of the currently configured users in the
user.map:
shell> tpm query usermap
# user.map Summary
# Configured users
app_user ******** alpha
# Script entries
# DirectRead users
# Host-based routing entriesReturns the version of the installed software:
shell> tpm query version
