InterSystems IRIS: Customer-Managed UDAF Installation

When configuring an InterSystems IRIS data warehouse, you must choose Customer managed as the Custom function installation mode, and you must manually install the AtScale UDAFs.

Selecting Customer managed gives the responsibility of installing and upgrading the AtScale UDAFs to the InterSystems IRIS administrator.

The following instructions explain how a InterSystems IRIS administrator can install or upgrade AtScale UDAFs on a InterSystems IRIS system.

InterSystems IRIS: download the binaries​

Go to the InterSystems WRC software download area and download the AtScaleUDAF.xml file for your InterSystems IRIS data warehouse. Note that this will require a login.

The following instructions use a schema ATSCALEUDAF. Modify the commands for your specific schema.

InterSystems IRIS: UDAF installation​

  1. Copy the .xml files to your InterSystems IRIS server (For example, in /tmp).

  2. From the IRIS terminal, run the following command to load the functions:

    do $system.OBJ.Load("/path/to/AtScaleUDAF.xml","c")

  3. To determine whether the installation was successful, run the following. It should return a valid version string.

    SELECT ATSCALE_HONEYBEE_VERSION()

  4. When configuringing the data warehouse connection, be sure to set the Custom function installation mode to Customer managed, and the UDAF schema to ATSCALEUDAF. For more information, see Adding InterSystems IRIS Data Warehouses.
