©Continuent 2013

One more reason why tpm is better

• Security:

• all data in transit (transaction history logs, or THL) is encrypted using SSL

• all administrative tra"c is encrypted with SSL

• Transparent to the user

• Independent of the database server (works also for heterogeneous replication)
