Custom Connection Properties

Ascend utilizes JDBC to connect to IBM DB2 on iSeries/AS400 which allows for many property specifications. The names of keys and values can be found in the IBM Toolbox for Java JDBC properties documentation.

Ascend specific formatting

To specify properties in Ascend, do not use quotations. Present each property as newline-delimited key=value pairs (see Figure 3 below for an example).
