Data Store Upgrades


When a TimesTen data store is loaded into shared memory, many of its
attributes are fixed, including size, logging options, TimesTen software

Starting with TimesTen version, TimesTen version numbers
consist of five components. Prior versions of TimesTen used only three
numbers to indicate the version, such as 5.1.35. The first two numbers in
the version are used to indicate a major release of TimesTen, such as
5.1.x or 7.0.x.y.z. The third number indicated the patch release of a
major release of TimesTen. For example, TimesTen version number
5.1.35 indicates the 35th patch release of TimesTen version 5.1.

TimesTen data stores are not compatible between major releases, but
they are always compatible between patch releases. For example, a data
store created with TimesTen version 5.1.35 is not compatible with a
TimesTen version application, but a data store created with
TimesTen will be compatible with a TimesTen version application.

When referring to a TimesTen version, the version number will often be
abbreviated to the major version number. For example, version
may be abbreviated to 7.0.
