ZENworks 11.2 Upgrade Pre Global Actions fail if SQL Server Instance is case-sensitive

Upgrading from ZCM 10.3 to ZCM 11.2

The upgrade fails during Pre-global Actions

From the ZENworks_Upgrade_<date>_<time>.log.xml:

Exception while upgrading database schema.
com.novell.zenworks.systemupdate.exceptions.SystemUpdateException: Unable to update database schema
Caused by: com.novell.zenworks.datamodel.exceptions.InternalDataModelException: Error executing SQL: CREATE PROCEDURE ZCM_PurgeHistory

From the pre-global-actions.log:

[PreGlobalAction]Error executing inventory_update.sql, will retry (1). Error: [Error executing SQL: CREATE PROCEDURE ZCM_PurgeHistory
Caused by: java.sql.SQLException: Must declare the scalar variable "@v_retaindate".

Verify if the SQL Server instance or database has case-sensitive collation
Run the following on the ZCM database:

Server instance:

SELECT SERVERPROPERTY('COLLATION');

Database:

SELECT DATABASEPROPERTYEX('<database-name>', 'Collation') SQLCollation;

If either of these have case-sensitive collation, follow the SQL Server documentation to change the collation to a case-insensitive one.

In one case, the server instance had the collation of "SQL_Latin1_General_CP850_BIN2". This is a case-sensitive collation.

A variable name in one of the Pre-global Action scripts is declared with a capital letter and then used as all lower-case.

The need for a case-insensitive instance for the ZCM database is covered in "Database Requirements", part of "System Requirements" in https://www.novell.com/documentation/zenworks11/zen11_installation/data/bookinfo.html
