xDB Systems works with a large energy company providing a variety of services.
We offer database specialists who provide immediate support and resources as needed. We frequently assist the in-house DBA resources with systems support and maintenance tasks. One of the key services we provide is 24/7 support of critical production systems as well as round the clock availability of Informix experts to resolve any immediate issues, giving the client peace of mind that their systems will have available support anytime they need it.
Along with our support services, we have performed Informix upgrades and helped complete multiple re-platforming projects. The systems rely on Informix’s TimeSeries functionality to efficiently store and process meter readings for several million meters, with frequent readings, resulting in a huge amounts of data – a single systems contains over 1.3 trillion meter readings and associated metrics. The systems are 24×7, and efficiency and uptime are paramount. We have worked on performance tuning, problem resolution, implementing backup strategies, and disaster recovery using replication between multiple data centers. We have moved their databases across different architectures from AIX to Solaris, AIX to Linux, and Solaris to Linux, while minimizing downtime and making sure that the systems are reliable and able to handle that volume of data.
Ongoing work for a large supermarket chain.
The xDB team has provided DBA support for a large chain of grocery stores for many years. As part of our work with them we have provided 24/7 support for all their Informix instances and replicated environments, and worked as their primary DBAs. Regardless of the time day or night we answer the needs of the customer with our team of database experts. Along with the regular support we have worked larger projects with the customer, including several Informix version upgrades which were performed successfully and with minimum downtime. We also have worked with them to set up, and later on upgrade, Connection Manager to support all of their many connections, and implement PAM authentication. They are heavily invested in Informix and we continue to have an extremely positive relationship with them.

We also have developed completely web based applications that are used to fulfil major parts of the organization’s mission. Along with the development projects, our team actively supports their web servers and services. This involves support for outages, monitoring, system migrations and upgrades, and includes support for their growing cloud infrastructure. Along with web support, we have provided extensive support and administration to several large WordPress installations, including writing a series of custom plugins to enhance the systems’ capabilities.
