Db2: Customer-Managed UDAF Installation

The following instructions explain how a Db2 administrator can install or upgrade AtScale UDAFs on a Db2 cluster, starting with downloading the binaries linked below.

Db2: Download the Binaries​

Follow this link to download the UDAF .tgz file for your Db2 Data Warehouse.

  1. Obtain the honeybee binaries, and copy the file to the Db2 server:

    scp db2honeybee.tar.gz user@db2server:/tmp

  2. Log in/SSH to the server as the target DB2 instance user. If there is a dedicated user for AtScale, use that user.

  3. Extract the .tar.gz file into the instance user's functions directory, for example:

    tar -xvzf /tmp/db2honeybee.tar.gz -C /database/config/atscale/sqllib/function``

Db2: Register the HLL functions​

  1. Connect to the database as the instance user and execute the following SQL script.

  2. To check if honeybee has been installed correctly, execute the following SQL command:

    select atscale_honeybee_version from SYSIBM.DUAL

  3. Choose Settings from the top navigation menu, select Data Warehouses, and edit the DB2 data warehouse. Select "Customer managed" for User Defined Aggregate Functions.
