|Product/Release:||Visual LANSA V11.3|
|Abstract:||LANSA now allows the creation of collections with new SQL Server databases|
|Submitted By:||LANSA Technical Support|
Support for SQL Server 2000 and SQL Server 2005 collections was delivered in V11.3 (CU3) and the text below was added to the LANSA documentation. The information provided below is very important to understand as it highlights that you cannot simply elect to upgrade an existing LANSA environment using an SQL Server database to 11.3 (CU3) and start using this new feature. A degree of planning and migration is required before an existing SQL Server database can avail of this newly supported SQL Server feature. Options and alternatives are discussed below.
LANSA V11.3 introduced a SQL Server database change.
This new feature of LANSA now allows the creation of collections with new SQL Server databases. This is a critical change to SQL Server functionality.
If you a) use SQL Server as your LANSA database, b) created it using a version of LANSA prior to LANSA 11.3 and c) have deployed applications that also use SQL Server, you MUST NOT use this new feature. You must continue to use a LANSA database created by prior versions of LANSA. This is because there is no migration possible from a database that does not support collections to one that does.
If you need to create a new installation of LANSA to maintain an application deployed prior to LANSA 11.3, then you must do one of the following:
- Install LANSA with a version of LANSA prior to 11.3
- Use an existing SQL Server database that was created a version of LANSA prior to V11.3.
If you need to start using a new version of SQL Server to maintain an application deployed prior to LANSA V11.3 (e.g. upgrading from SQL Server 2000 to SQL Server 2005), then you must do one of the following:
- Use SQL Server administration utilities to directly upgrade the SQL Server 2000 database to SQL Server 2005
- Use SQL Server administration utilities to export the entire SQL Server 2000 set of schema and data and import it to the SQL Server 2005 database
- Install LANSA to the SQL Server 2005 database with a version of LANSA prior to LANSA V11.3.
This feature is only available for use with applications that have not yet been deployed with a version of LANSA prior to LANSA V11.3. This also includes test environments that contain test data that must be retained.
If you are already using an Independent LANSA System created with a version of LANSA prior to LANSA V11.3 - one that does not have a System i Master - then you also CANNOT start using collections. This is because there is no migration possible.
If you are already using a Slave LANSA System created with a version of LANSA prior to LANSA V11.3, and that has not yet been eliminated because of one of the reasons described above, then provided you have checked all your changes into the System i you can use this new feature.
To use this new feature, create a new SQL Server database and then install LANSA to it. Collections will be automatically used.
