  • Unable to connect remote source: exception 151044: Agent "DPAgent_ID" is not available. , Code: 5921, SQL State: HY000

Environment

SAP Datasphere

Resolution

Follow these steps:

  1. Download and upgrade into latest DP Agent version (see KBA 2563103 - How to check the Data Provisioning Agent version).
    • Latest version can be identified in the following location on the SAP for Me Software Center → Support Packages & Patches tab → By Alphabetical Index (A-Z) → H → SAP HANA SDI > SAP HANA SDI <version_number> → Comprised Software Component Versions → HANA DP AGENT 2.0

  2. Verify that the external/public IP (IP for untrusted networks) of the server where the DP Agent is installed is allowlisted (see SAP Note 2894588 - IP Allowlisting in SAP Datasphere)
    • Allowlist is NOT relevant for private IP ranges (10.0.0.0 ~ 10.255.255.255, 172.16.0.0 ~ 172.31.255.255, 192.168.0.0 ~ 192.168.255.255)
      Trusted networks use private IP addresses to communicate within trusted environment.
      Communication between the trusted networks over an untrusted network, use a single public IP address. Network Address Translation (NAT) manages this communication.
      Therefore if the DPAgent is installed in a private network, make sure to add the public IP address into SAP Datasphere's Allowlist for untrusted networks. 

    •  To determine the external IP proceed:

      1. In Linux, run from the terminal: curl ifconfig.me OR dig +short myip.opendns.com @resolver1.opendns.com

      2. In Windows, run from CMD: nslookup myip.opendns.com. resolver1.opendns.com

  3. Verify if there is a firewall that can block outbound requests
  4. Perform command telnet in the agent side to SAP Datasphere tenant on HANA port 443
  5. When using proxy,  the proxy's address needs to be included in Datasphere's IP Allowlist as well
  6. Check all points of the Troubleshooting Guide for the DP Agent step by step: Troubleshooting Guide
