Problem

FATAL [Startup] (ClusterMaintenanceManager.halt:134) - Fatal error while performing schema maintenance

java.sql.SQLException: There is already an object named 'InstalledComponents' in the database.

Resolution

This is because the database has set as case sensitive for Table name and Column as well in addition to data. But only the Data should be case sensitive not the Table and Column. This issue mostly seen with MSSQL server.

In order to resolve this please select an appropriate value of collation while creating as database. For ex-

SQL_Latin1_General_CP1_CI_AS --> Where 'CI' refers to Case Insensitive.
