Reviewing technical changes in IBM App Connect Enterprise Version 11.0

Some minor changes in behavior are present in IBM® App Connect Enterprise Version 11.0; for example, those changes that are caused by defects that were fixed between versions.

If you are migrating from Version 9.0, read the following sections to understand the potential effects on your integration nodes and message flows::

Improvements in DFDL schema validation

The IBM implementation of DFDL has added extra validation checks to comply with the DFDL 1.0 specification. When a DFDL schema that is created in a previous version of IBM App Connect Enterprise or WebSphere® Message Broker is validated in the IBM App Connect Enterprise Toolkit or during deployment, errors are reported under the following conditions:
  • The DFDL property length of an element must not exceed the capacity of the element's simple type. If the validation fails, the following error is generated: CTDV1534E. To prevent the error, change the simple type of the element so that it can cope with the length. For example, if a "two's complement" binary number has the DFDL property length set to 8 and the type is xs:int, change the type to xs:long to clear the error.
  • When the DFDL property initiatedContent is set to yes on the parent sequence or choice, additional checks are made on elements and groups. If the validation fails, one or more of the following errors are generated: CTDV1561E, CTDV1560E, or CTDV1431E. To prevent the error, set initiatedContent to no on the parent sequence or choice. However, if a new error (CTDV1559E) then appears, contact IBM support for further advice.
  • When the parent sequence or choice is the content of a global group, and DFDL properties are placed on group references to the group, additional cross-checks are made between DFDL properties of elements and groups, and DFDL properties on the parent sequence or choice. If the validation fails, one or more of the following errors are generated: CTDV1150E, CTDV1118E, CTDV1432E, CTDV1446E, CTDV1466E, or CTDV1467E. To prevent the error, correct the schema in accordance with the indicated error.
  • When the DFDL property occursCountKind of an element is set to parsed, and the parent sequence has a separator, the DFDL property separatorSuppressionPolicy of the parent sequence must be set to anyEmpty. If validation fails, the following error is generated: CTDV1625E. To prevent the error, correct the sequence so that the DFDL property separatorSuppressionPolicy is set to anyEmpty, or change the element so DFDL occursCountKind is set to implicit.
  • The DFDL property fillByte must resolve to a single-byte value. If validation fails, the following error is generated: CTDV1458E. To prevent the error, correct the DFDL property fillByte to use a single DFDL entity that resolves to a single-byte value.
