Your expert for Oracle and PostgreSQL databases

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.

We have engaged CarajanDB GmbH to support our internal administrators with our database infrastructure, and we are very satisfied with their services. From the very beginning, the collaboration was highly professional and efficient. The colleagues at CarajanDB possess not only extensive expertise in database administration but also an excellent understanding of the specific requirements of our company.
The regular maintenance and optimization of our databases were always carried out successfully and with high precision. In the event of any issues, the colleagues from CarajanDB GmbH were quick to respond and resolved them in a highly competent manner. We particularly appreciated their proactive communication and the transparent reporting on announced versions, patches, or changes from the database manufacturers.
Thanks to the support of the colleagues at CarajanDB GmbH, we were able to significantly improve the performance of our database while ensuring the security of our data. I can recommend CarajanDB GmbH without reservation and look forward to continued successful cooperation.

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.
