Before you can use this product to deploy SQL applications developed for .NET managed COBOL with COBSQL, DB2 ECM or OpenESQL, ensure any third-party software prerequisites are installed and the environment is set properly. 
	 
 
	  
		 
		  - HCO for SQL Server (HCOSS) 
		  
-  
			  
				 
				  - Microsoft SQL Server 
				  
-  SQL Server 2008, SQL Server 2008 R2, or SQL Server 2012, Developer or Enterprise Editions. 
				  
- Database Migration 
				  
-  
					  
						- Microsoft OLE DB Provider for DB2, available in the SQL Server 2008 or 2012 Feature Pack 
						
- Mainframe DB2 
						  Note: We support only the mainframe DB2 versions that are currently under IBM support. 
						   
 
 
- Application Migration 
				  
-  
					  
						 
						  - ADO.NET applications 
						  
- ADO.NET applications require either of the following combinations: 
							  
								- SQL Server 2008 and SqlClient Data Provider in .NET Framework 3.5 
								
- SQL Server 2012 and SqlClient Data Provider in .NET Framework 3.5 or 4.0 (4.0 is preferred) 
								
 
- COBOL Stored Procedures 
						  
- See the requirements specified in the 
							 SQL CLR Integration section below. 
						  
 
 
- OpenESQL 
		  
-  
			  
				-  Database access is supported using the OpenESQL preprocessor with applications compiled as .NET managed code to access relational databases using ODBC 3.0-compliant drivers. Refer to your driver vendor's documentation to determine whether your driver is suitable for use with OpenESQL. 
				
- OpenESQL has been tested against the following ADO.NET data providers: 
				   
					 - Microsoft provider for SQL Server 
					 
- Microsoft provider for Oracle 
					 
- IBM DB2 
					 
- Oracle Data Provider for .NET (ODP.NET) 
					 
- OleDb 
					 
- Managed ODBC .NET providers 
					 
 
- Dynamic SQL using the SQL Descriptor Area (SQLDA) is not currently supported for OpenESQL applications compiled with the SQL(DBMAN=ODBC) directive.
