CICS® periodically monitors the state of unallocated user region (24-bit) and extended user region (31-bit) MVS storage available to the CICS address space.

IBM CICS (Customer Information Control System) is a family of mixed-language application servers that provide online transaction management and connectivity for applications on IBM mainframe systems under z/OS and z/VSE. CICS family products are designed as middleware and support rapid, high-volume online transaction processing.

To optimize your use of the MVS storage and to avoid region abends due to short-on-storage (SOS) conditions, you can use CICS® monitoring support and the SOS wait feature for 24-bit and 31-bit user region storage.

Multiple Virtual Storage, more commonly called MVS, is the most commonly used operating system on the System/370, System/390 and IBM Z IBM mainframe computers. IBM developed MVS, along with OS/VS1 and SVS, as a successor to OS/360. It is unrelated to IBM's other mainframe operating system lines, e.g., VSE, VM, TPF.

You can improve the performance of your Java™ applications and the JVMs in which they run by analyzing and tuning your CICS regions. MVS and DASD: performance and tuning Tuning CICS for virtual storage under MVS depends on several elements: z/OS systems tuning, z/OS Communications Server SNA tuning, CICS tuning, and VSAM tuning.

CICS allows users to develop and execute online application in an MVS environment. CICS has become the most commonly used server for Internet applications. CICS is a transaction processing system which is also called as Online Transaction Processing (OLTP) Software.

CICS (Customer Information Control System) is middleware that sits between the z/OS IBM mainframe operating system and business applications. As an online transaction processing ( OLTP ) system, it is used to build customer transaction application programs.

KICKS is an enhacement for CMS and TSO on IBM mainframes and emulators that lets you run your CICS applications directly instead of having ot install those apps in CICS. You don't even need CICS itself instald on your mainframe. KICKS is …

It enables you to issue various operator-oriented CICS transactions (CEMT) through the z/OS MODIFY console command if security and console definitions are properly defined to CICS.
