Upgrade Of Existing Repository

...

  • From host script set the script type of wsl_post_install_enablement_pack as Auto Execute - PowerShell Script

    Image Removed Image Added
Important Upgrade Notes
If RED upgrades the repository option is chosen.
This enablement pack will overwrite any existing Source Enablement Pack UI Configs:

...

  1. Connection: 'Database Source System' - this connection was set up as an example source connection,
    • open it's properties and set it up for a source DB in your environment
    • or you can remove it if not required
  2. Execute Update Procedure for dim_date_td to Initialize Date Dimension for Target

Image RemovedImage Added

Note

Please avoid regenerating the procedure update_dim_date_td as it is a custom procedure.

...

Some of the setup scripts will track each step and output the step number when there is a failure. To restart from the failed step (or to skip the step) provide the parameter -startAtStep <step number> to the script.
Example: 
Powershell -ExecutionPolicy Bypass -File .\<script_file_name.ps1> -startAtStep 123

Tip

T To avoid having to provide all the parameters again you can copy the full command line with parameters from the first "INFO" message from the beginning of the console output.
