23. Oracle GoldenGate
Conclusion
+ GoldenGate avoids any production downtime and business
loss during cross-platform database migration and upgrade
+ GoldenGate allows to benefit from each infrastructure
investment, providing data reporting on the target site
+ GoldenGate supports large data volume for large mission-
critical businesses
 GoldenGate allows Zero downtime application modification
and upgrade with some additional coding effort
 However, according to dbi services expertise Data Guard
remains the best solution for High Availability:
 No synchronous transaction transfer
 No possibility for No Data loss setup
 Not a 100% identical Database (only a logical copy)
 Do you really want Cross Platform High Availability ?
