SAP Note 784568 - DB6: fullyMaterializeLobData=false

Component : DB2 Universal Database for Unix / NT -

Solution : https://service.sap.com/sap/support/notes/784568 (SAP Service marketplace login required)

Summary :
During the execution of a JDBC-based application on DB2, a `DisconnectException` error may occur due to attempts to fully materialize large LOB (Large Object) data, exceeding the Java VM’s capacity. The default configuration of the DB2 JDBC driver, type 4, materializes LOB data during the fetch process. This can be modified by setting "fullyMaterializeLobData=false" to manage LOBs with locators, saving memory. Applications might face reentrant calls issues, but versions post-DB2 V8 SP10 have a setting to circumvent this. However, complete materialization is recommended to avoid larger memory consumption during batch operations with LOBs.
