| <div class="block"><b>Database Platform for SAP MaxDB.</b> |
| <p> |
| <a href="http://wiki.eclipse.org/EclipseLink/Development/DatabasePlatform/MaxDBPlatform"><b>Wiki page</b></a> |
| <p> |
| <b>Usage</b> |
| <p> |
| The MaxDB platform is configured in the persistence.xml by the following property: |
| <p> |
| <code><property name="eclipselink.target-database" value="MaxDB"/></code> |
| <p> |
| Forward mapping with EclipseLink assumes that MaxDB is configured for unicode (in version 7.7, this is the default). Unicode mode also needs to be specified in the URL as follows: |
| <p> |
| <code>jdbc:sapdb://localhost/E32?unicode=yes</code> |
| <p> |
| <b>Tested with:</b> |
| <ul> |
| <li>DB: MaxDB, kernel 7.8.01 build 004-123-218-928</li> |
| <li>JDBC driver: MaxDB JDBC Driver, SAP AG, 7.6.06 Build 006-000-009-234 (Make-Version: 7.8.01 Build 003-123-215-703)</li> |
| </ul> |
| |
| <b>Limitations:</b> |
| <br> |
| <ul> |
| <li>The platform class must not be used with XA transactions - see bug 329773.</li> |
| <li>SetQueryTimeout or the hint "jakarta.persistence.query.timeout" do not work on MaxDB - see bug 326503.</li> |
| <li>The hint "jakarta.persistence.lock.timeout" has no effect with a positive value; a value of 0 is translated to NOWAIT.</li> |
| <li>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.</li> |
| <li>VARCHAR [UNICODE] columns do not preserve trailing spaces - see bug 327435.</li> |
| <li>VARCHAR BYTE columns do not preserve trailing 0 bytes.</li> |
| <li>The hint "jakarta.persistence.lock.timeout=0" (NOWAIT) has no effect when atempting to pessimistically lock an entity with inheritance type JOINED - see bug 326799.</li> |
| <li>Pessimistic locking with lock scope EXTENDED should be used cautiously in the presence of foreign key constraints - see bug 327472.</li> |
| |
