Requirements for Replication Compatibility
TimesTen replication is supported only between identical platforms and bit-levels. Although you can replicate between databases that reside on the same host, replication is generally used for copying updates into a database that resides on another host. This helps prevent data loss from host failure.
Starting with Release 26.1, on Linux and UNIX, TimesTen has strengthened password security by adopting a stronger hashing algorithm. For replication between different major versions of TimesTen, the Times databases (on all the replication peers) must be one of the following releases to support the stronger algorithm and avoid authentication issues:
- Release 26.1.1.1.0 or later for TimesTen 26.1
- Release 22.1.1.36.0 or later for TimesTen 22.1
- Release 18.1.4.54.0 and later for TimesTen 18.1
The databases must have DSNs with identical value in the DatabaseCharacterSet database connection attribute.
