Retrieving information about versions

Learn how to retrieve information about replication version for a single node or all nodes.

1. Log in to the Netezza Performance Server container as the nz user.

   ssh nz@APPLIANCE HOSTNAME -p 51022

2. Locate the nzdr utility in the /nrs directory.
3. Retrieve information about version.

   nzdr version [--node-name] [-j]

   Example:

   • To retrieve information about version for a single node, run:

     ./nzdr version --node-name NODE NAME

     Example:

     [root@e1n1 nps]# ./nzdr version --node-name CPDS-A
     +-------------+-----------+
     | node-name   | version   |
     +=============+===========+
     | CPDS-A      | 3.0.0.0   |
     +-------------+-----------+ 

   • To retrieve information about version for a single node in JSON, run:

     ./nzdr version --node-name NODE NAME -j

     Example:

     [root@e1n1 nps]# ./nzdr version --node-name CPDS-A -j
     [
       {
         "node_name": "CPDS-A",
         "version": "3.0.0.0"
       }
     ]

   • To retrieve information about versions for all nodes, run:

     ./nzdr version

     Example:

     [root@e1n1 nps]# ./nzdr version
     +-------------+-----------+
     | node-name   | version   |
     +=============+===========+
     | CPDS-A      | 3.0.0.0   |
     +-------------+-----------+
     | CPDS-B      | 3.0.0.0   |
     +-------------+-----------+ 

   • To retrieve information about versions for all nodes in JSON, run:

     ./nzdr version -j

     Example:

     [root@e1n1 nps]# ./nzdr version -j
     [
       {
         "node_name": "CPDS-A",
         "version": "3.0.0.0"
       },
       {
         "node_name": "CPDS-B",
         "version": "3.0.0.0"
       }
     ]
