How to relocate DAB_NEXUS_HOME to a new drive?

Why can it be necessary to relocate the DAB_NEXUS_HOME directory?​

If you often use the dab Nexus Replication Tasks with large amounts of data, you may encounter the following error message: Download failed: There is not enough space on the disk. This is because Real-Time objects and Parquet files are written locally before being sent to the designated Cloud Connection (Fabric, Snowflake, etc.).

To resolve this issue, the DAB_NEXUS_HOME directory should be relocated to a drive with more disk space.

Note

Before starting the relocation, please ensure that the user running the dab Nexus Service has authorization to write data to the new location.

  1. Stop the Windows Service for dab Nexus

  2. Change the System Variable for DAB_NEXUS_HOME

    • Open the Start menu and search for "Edit the system environment variables" (this name may vary)
    • Search for the System Variable DAB_NEXUS_HOME
    • Save the current path per copy & paste and then change the value to the new path
    • Save your changes

  3. Test the new System Variable

    • Open the Data Explorer
    • Enter %DAB_NEXUS_HOME% in the path line and press ENTER
    • You should now be redirected to the new location for the dab Nexus data. If not, please check the system variable again!

  4. Make sure you relocate all files and directories from the old path to the new one. Please don't leave any behind!
