JKLINT is the system that JKL uses for their Web site and e-mail. While this data is critical to their business, it is fairly static.
They need 24x7 availability for the critical data on this server, and they accomplish that by having a second server, JKLINT2, that shadows JKLINT. They use a high availability replication solution to copy the data from JKLINT to JKLINT2. Then, if JKLINT goes down, they can switch to JKLINT2.
Since Sharon is using a high availability solution she uses remote journaling with the two servers. Scenarios: Remote journal management and recovery description shows the different ways that Sharon can set up remote journaling between JKLINT and JKLINT2.
