Upgrade Of Existing Repository

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

Image Removed Image Added
Important Upgrade Notes
If RED upgrade the repository option is chosen.

This enablement pack will overwrite any existing Source Enablement Pack UI Configs:

...

To ensure existing Source Enablement Pack connections and associated Load Tables continue to browse and load:
Go into UI Configuration Maintenance in RED prior to installing this Enablement Pack and rename the affected UI Configurations. While the updated Load Template will work with previous Source Enablement Pack's we recommend moving these previous versions of Load Tables to newly created Parser based connections following this install. The earlier versions of the Source Enablement Pack will be deprecated following this release.

Post Install Steps – Optional

If you used the script Setup Wizard for installation then the following optional post install steps are available.

...

Connection: 'Database Source System' - this connection was setup 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
Execute Update Procedure for dim_date_azsql to Initialize Date Dimension for Target

NOTE: Please avoid regenerating the procedure update_dim_date_azsql as it is a custom procedure.
For Azure SQL Target following extended properties will require your attention:

...

Run below queries in azure sql database query editor.
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '<MASTER_KEY>';
CREATE DATABASE SCOPED CREDENTIAL <BlobStorageCredential> WITH IDENTITY = 'SHARED ACCESS SIGNATURE', SECRET = '<SAS_TOKEN>';
DROP EXTERNAL DATA SOURCE <Blob Data Source>;

Troubleshooting and Tips

Run As Administrator

Press the Windows Key on your keyboard and start typing cmd.exe, when the cmd.exe icon shows up in the search list right click it to bring up the context menu, select "Run As Administrator"
Now you have an admin prompt navigate to to the folder where you have unpacked your WhereScape Red Enablement Pack to using the 'cd' command:
C:\Windows\system32> cd <full path to the unpacked folder>
Run Powershell (.ps1) scripts from the administrator prompt by typing the Powershell run script command, for example:
C:\temp\EnablementPack>Powershell -ExecutionPolicy Bypass -File .\Setup_Enablement_Pack.ps1
Notes: In the event you can not bypass the Powershell execution policy due to group policies you can instead try "-ExecutionPolicy RemoteSigned" which should allow unsigned local scripts.

Windows Powershell Script Execution

On some systems, Windows Powershell script execution is disabled by default. There are a number of several workarounds for this which can be found by searching the term "Powershell Execution Policy".
Here is the most common workaround which WhereScape suggests, which does not permanently change the execution rights:
Start a Windows CMD prompt as Administrator, change directory to your script directory and run the WhereScape Powershell scripts with this command:

...

Bulk load error on SQL SERVER

Interactive load
Image RemovedImage Added
Scheduler load
Image RemovedImage Added
For bulk load error, the 'bulkadmin' permission is required.
SQL SERVER -> SECURITY -> LOGINS -> USER -> PROPERTIES ->SERVER ROLES
Image RemovedImage Added

For bulk load error Operating system error code 5(Access is denied)

...

Grant SQL Server access to the bulk load folder by adjusting folder permissions. Navigate to the folder, right-click, select "Properties," go to the "Security" tab, click "Edit," then "Add." In the new window, select "Advanced," click "Find Now," and locate the appropriate SQL Server user (e.g., SQLServerMSSQLUser$UserName$SQLExpress). Confirm by clicking "OK" through all opened dialogs.
If the first fix doesn't resolve the issue, verify if permissions are applied to subfolders as well. Navigate to the advanced settings, and check the 'Inheritance' status. If it's 'Disabled,' enable it by using the "Allow Inheritance" button.

If you have RED 10.x or higher installed but the script (Setup_Enablement_Pack.ps1) fails to find it on you your system then you are most likely running the PowerShell (x86) version which does not show installed 64-bit apps by default. Please open a 64-bit version of Powershell instead and re-run the script.
