1.1Changes for Release 11.2.1.7.0 from Release 11.2.1.6.6

The file is no longer included in the installation directory.

Behavior changes are included in this document.

1.1.1Behavior changes in Release 11.2.1.7.0

■

Previous behavior: If SUBSTR() result is longer than the target column, the result

is silently truncated and an insert or update succeeds with the truncated string.

New behavior: If the result of SUBSTR() is longer than the target column in an

insert or update statement, the operation fails with error 982: "String

exceeds column width". For example, if column x is of type CHAR(4), SET

x=SUBSTR('abcdefg',2) results in error 982. SUBSTRB() in a multibyte

character set continues to silently truncate the string, and insert or update

continues to succeed with the truncated string.

1.1.2New features and changes in Release 11.2.1.7.0

See the "What's New" prefaces in the documentation to see the new features

documented in a specific guide.

■

You can create an explicitly loaded global cache group in a cache grid. If the cache

tables on the local grid member do not contain data that satisfies a query, then the

cache instance is transferred from other grid members to the local grid member in

a grid data transfer operation. If the grid does not contain the cache instance that

satisfies the query, data is not loaded from the Oracle tables and the query returns

no results. See Oracle In-Memory Database Cache User's Guide.
