What our customers say
Experience firsthand how our expertise helps businesses achieve success
In 2018, we were faced with the problem that Oracle had discontinued the use of RAC for Standard Edition 2. CarajanDB helped us to migrate to the alternative Standard Edition 2 High Availability and Oracle 19c without any restrictions. Today, we benefit every day from the robustness of the system.
In 2015, we redesigned our Oracle infrastructure. CarajanDB convinced us with its expertise to utilize Oracle RAC, Data Guard, and the then-new multi-tenant architecture. In addition to the planning and implementation, CarajanDB consistently supported us with suitable workshops.
November 2021 was a dark month for us. We were hit by a ransomware attack that crippled all our IT systems. Our important Oracle databases were also infected. When we attempted to restore a backup, we found that those were also unusable. The experts from CarajanDB were able to get the old databases running again within a day.
The CarajanDB experts have been supporting us in managing our Oracle databases since 2011. Thanks to the remote maintenance contract, we enjoy high system reliability. Our staff received training from CarajanDB, enabling them to manage the databases independently, always with the assurance that an expert can be called upon if necessary.
Since 2020, we have had a remote maintenance contract with CarajanDB. The proactive monitoring gives us a lot of security, as we receive early information about bottlenecks. Through workshops on Oracle Multitenant and Quest Toad for DBAs, we were optimally prepared for the recent migration of the databases to Oracle 19c. The related transition from Windows servers to Oracle Database Appliances was also optimally supported by CarajanDB.
In 2018, we faced the issue that Oracle had discontinued the use of RAC for the Standard Edition 2. CarajanDB helped us migrate to the alternative Standard Edition 2 High Availability and Oracle 19c without limitations. Today, we benefit from the robustness of the system every day.
