Frequently Asked Questions
IBM i support and maintenance covers day-to-day issue resolution, proactive application maintenance, and ongoing monitoring to keep your systems secure, stable, and up-to-date. Proximity combines reactive helpdesk cover (with SLA-backed response times) with proactive work that prevents issues arising in the first place. Proactive maintenance keeps your IBM i applications updated, secure and addresses potential issues before they become support tickets. We use automated performance tracking to ensure problems are caught before they become an issue.
Typically support is provided on a 5-day working week based on ‘normal’ UK working hours, Proximity can provide SLA-backed extended hours, including 24/7 support for business-critical IBM i (iSeries and AS400) applications on request. All support is delivered against guaranteed response times so urgent issues are resolved promptly and any downtime is minimised. Proximity has a UK-based team of 40-plus IBM i technical specialists, not an outsourced call centre.
IBM i software support covers the operating system, security patches, and platform-level stability, while IBM i application support covers the day-to-day functioning of the business applications running on top of it. Most organisations need both working together to keep the whole environment reliable.
- Software support: OS updates, security patching, and platform configuration
- Application support: resolving issues, fielding user queries, and maintaining the business logic.
Proximity provides application support rather than software support. However, we do have a network of partners who can provide that exact service as part of their offering.
Yes, it is certainly possible to transfer your IBM i developers to Proximity. It is a model we have employed with other IBM i enterprises. If you’re looking to outsource the support and maintenance of your existing IBM i applications, we are always open to finding a ‘good home’ for your existing in-house IBM i developers or support staff. This preserves continuity and avoids the disruption of starting support from scratch (though we do have a tried and tested methodology for knowledge transfer should that be your preference). In our experience, enterprises looking for this option are planning to migrate from IBM i in the medium to long-term, which again is something we can support you with.
Proactive IBM i application maintenance and support provided by Proximity helps prevent downtime by identifying and resolving issues before they escalate any further, rather than waiting for something to break. When supporting and maintaining an IBM i application, we typically include a continuous performance monitoring tool, which has been designed and developed by us, within the service. That automated performance tracking and anomaly detection flag problems before users notice them and reduces support ticket volume overall, since many issues are caught and fixed proactively.
