Mainframes & Legacy Applications

Mainframe applications are often the most critical applications in the organization. For many firms IBM zSeries machines represent the mainstay processors and are looked to for their outstanding reliability, availability and serviceability. Terres Technology has actively supported mainframe applications and associated technologies. Members of our staff are knowledgeable in TPF, VSAM, CICS, JCL and OS utilities, as well as coding languages and DBMS that are commonly used on mainframe machines.
Many of our clients depend upon older technologies to process their core operational systems. These technologies have proven to be stable and reliable components of their IT infrastructure. With decades of experience in the computer industry, we offer support in a wide range of technologies which include non-relational databases and less frequently used programming languages.
