Maintenance

Routine maintenance for Datamotive nodes: verifying services, validating connectivity, replacing SSL certificates, and generating support bundles when escalation is needed.

Verify Datamotive services

If the console at https://<management-node-ip>:5000 is unreachable, SSH into the node and check service status.

systemctl status mysqld
systemctl status nginx
systemctl status dm-auth
systemctl status dm-mgmt
systemctl status dm-repl-server
systemctl status dm-repl-client
systemctl status dm-mon

systemctl restart mysqld
systemctl restart nginx
systemctl restart dm-auth
systemctl restart dm-mgmt
systemctl restart dm-repl-server
systemctl restart dm-repl-client
systemctl restart dm-mon

Validate network connectivity

From the management node:

# management -> replication node
telnet <replication-node-ip> 5003
telnet <replication-node-ip> 5002
telnet <replication-node-ip> 5001
# management -> remote management node
telnet <remote-management-node-ip> 5000
# management -> prep node (WinRM)
nc -z -w1 <prep-node-ip-or-hostname> 5985; echo $?
# management -> dedupe node
telnet <dedupe-node-ip> 5005

From a replication node:

# replication -> management node
telnet <management-node-ip> 5000
telnet <management-node-ip> 5002
telnet <management-node-ip> 5001
telnet <management-node-ip> 3308
# replication -> remote replication node
telnet <remote-replication-node-ip> 5001
telnet <remote-replication-node-ip> 5002

For cloud deployments, also validate external access (for example ping www.google.com). If problems persist, contact support@datamotive.io.

Replace the SSL certificate

Nodes ship with a self-signed certificate; the GUI and APIs are served over TLS 1.3. To install a CA-signed or custom certificate:

1. Generate a CSR on the management node

   SSH in, elevate permissions, then:

   bash

   cd /home/dmadmin && mkdir cert && cd cert
   openssl req -newkey rsa:4096 -nodes -keyout server.key -x509 -days 365 -out server.cert

   Use the CSR to obtain your CA certificate.

2. Run the replacement script

   Download nginxCertsReplace.sh from the Datamotive releases bucket and run it on the management node:

   bash

   ./nginxCertsReplace.sh <new-key-file> <new-crt-file>

   Authenticate with the console Administrator user and password when prompted.

Generate a support bundle

Under Settings → Tech Support, click + Generate, describe why the bundle is needed, and click Generate Bundle. The node collects the required diagnostics; refresh the list to track status. Once complete, download the bundle via the download icon (or delete it) and attach it to your support case.
