Note: This page describes an extension of EclipseLink that is part of the EclipseLink incubator. Incubator projects are published so the community can use them either to progress towards having them included in the main product, or to use in their own implementations. They have been tested to varying levels and as such, we recommend doing your own testing before including any of this code in a production-level product.
Contents
Bug
- bug 284657 Support for MaxDB / SAPDB
Description
This is a subclass of DatabasePlatform that can be used by customers using the MaxDB database.
Documentation
MaxDB uses URL that may contain the ampersand (&) character, e.g.
jdbc:sapdb://localhost/E32?spaceoption=true&unicode=yes
Please make sure that this character is escaped properly in XML files.
In order to execute the eclipselink tests, the ampersand must also escaped in an URL contained in a test.properties file.
Limitations of the Platform
- SetQueryTimeout or the hint "javax.persistence.query.timeout" do not work on MaxDB - see bug 326503.
- The hint "javax.persistence.lock.timeout" has no effect with a positive value; a value of 0 is translated to NOWAIT.
- The maximum width of an index is 1024 bytes on MaxDB. This also limits the size of a primary key. Moreover the primary key of join tables must not exceed this limit either. As it is composed of the primary key of the two tables that are joined, the combined width of the PKs of these two tables must not exceed this limit. See bug bug 326968.
- VARCHAR [UNICODE] columns do not preserve trailing spaces.
