'''OpenFrame''' is a [[Mainframe computer|mainframe]] rehosting solution developed by [[TmaxSoft]]. OpenFrame aims to help customers move existing mainframe assets to the [[Cloud computing|cloud]] quickly and with minimal risk.<ref>{{Cite news|url=https://www.tmaxsoft.com/products/openframe/|title=Mainframe Rehosting {{!}} OpenFrame{{!}} TmaxSoft|work=TmaxSoft|access-date=2017-11-02|language=en-US}}</ref>

'''OpenFrame''' is a Mainframe legacy rehosting solution that enables mainframe assets in a mainframe legacy system to be migrated to a more reliable and high performance open system. OpenFrame has been chosen as the replacement IT infrastructure for many leading companies around the world. <ref>http://www.tmaxsoft.com/bbs.do?cms_cd=ABO_10. Retrieved 2014-02-27.</ref><br />

'''OpenFrame''' is comprised of a number of different elements required to provide replacement features and functionality for a legacy mainframe system to be migrated and run in an open system environment. These correspond to elements of a mainframe system and include; OpenFrame Online, OpenFrame Batch, OpenFrame OSC for IBM CICS, OpenFrame OSI for IBM IMS, OpenFrame Web, OpenFrame TACF, OpenStudio and SysMaster for OpenFrame.<br />

OpenFrame can be used to Migrate the applications resources and datasets from Legacy IBM, Fujitsu and Hitachi mainframe systems. In the majority of cases applications run on a mainframe system can be automatically converted to run in an Open Environment with little or no change to the original source code or business logic.<br />

== Features ==

OpenFrame's key features revolve around the ability to transition to the cloud with minimal disruption to business activities, including no change to the [[User experience|end-user experience]] and no need to review [[Legacy system|legacy]] code for efficiency.

The main feature of '''OpenFrame''' is that it is possible to migrate applications, resources, and data from a mainframe system to an open system, without modifying the original business logic. <ref>OpenFrame White_Paper: Legacy Modernization through Rehosting http://www.platformmodernization.org/tmaxsoft/Lists/ResearchPapers/Attachments/2/OpenFrame_White_Paper.pdf. Retrieved 2014-02-27.</ref><br />

Switching to OpenFrame® can reduce the [[Total cost of ownership|TCO]] (60%) of the existing system.<ref>http://eyeball.bloter.net/archives/1674. In Korean. Retrieved 2014-02-27.</ref>,<ref>http://www.tmaxsoft.com/product/productView.do.

Retrieved 2014-02-27.</ref>. <br />

The main components of an '''OpenFrame''' solution are as follows:<br />

* '''OpenFrame Online'''

OpenFrame Online handles user requested programs and allows [[CICS|CICS]] / [[IMS|IMS]] programs to run without modification to the original source code or changes to functionality.<br />

* '''OpenFrame Batch'''

OpenFrame/Batch is used to run JCL batch jobs in OpenFrame. These are typically run after hours. OpenFrame/Batch offers the following features:<br />

JCL and batch applications can be migrated from a mainframe and run without modification to the original source code or the business logic and therefore avoiding the risks caused by program redevelopment.<br />

New batch jobs can be developed easily by using applications provided by the UNIX system.<br />

If real or virtual nodes fail unexpectedly, OpenFrame's fail-over functions automatically reroute

transactions to other available nodes. After the node failure is detected, an automatic recovery

of the failed node can be performed by the Tmax server.

OpenFrame Batch provides a host of tools to migrate applications from the mainframe to an open system environment, as well as the libraries needed to develop new tools and utilities. Many of the utility programs used in the existing MVS [[Job Control Language|JCL]] can be executed in a batch environment.

* '''OpenFrame TACF'''

Security and permission management is provided by OpenFrame TACF which is comparable to [[RACF|RACF]] in a mainframe system. OpenFrame/TACF uses a Tmax CS (client/server) type interface, as well as API type interfaces. The main features of OpenFrame/TACF are as follows:<br />

'''User Authentication:''' Users must possess a valid ID and password to access resources within OpenFrame.<br />

'''Resource Access Control:''' The administrator can define the specific resources that each user can access.<br />

'''Resource Access Log:''' TACF records a range of system statistics, such as connection times, access counts, resources

accessed, etc. These log records are the source for providing statistical reports and analyzing user behavior and resource usage trends.<br />

* '''SysMaster for OpenFrame'''

'''Tmax SysMaster''' is an [[Application Performance Management|APM]] solution that manages a wide range of enterprise system components. It supports efficient resource management by enabling identification of IT infrastructure status and error causes and supporting statistics analysis for applications such as [[Application Servers |WAS]] Web Application Servers, [[TP-Monitor|TP-Monitors]], [[database|databases]], and [[framework|frameworks]].

* '''OpenStudio'''

OpenStudio is a GUI-based tool for analysis, control, and development of the processes for OpenFrame. It provides effective monitoring and optimization functions for the system environment.

'''OpenStudio''' consists of a client application and RMI Based Objects. The client Application (OpenStudio Client)is based on the Eclipse Rich Client Platform and a Java server (OpenStudio Server) for interfacing and secure handling of the OpenFrame system. The structure of OpenStudio Server follows the master/agent model. The master is responsible for communications within the OpenFrame system, and the agent is responsible for communicating with particular machines.

The RMI (Remote Method Invocation) based objects such as OSM, DEV, DEP, OMC, BM and TM, contain client modules developed by the Eclipse Project. Modules are standalone allowing easy updates, development, customization and inter-operability.<br />

The main features of OpenStudio are as follows:<br />

'''Easy-to-use user interface:'''

As a tool which provides an overall user interface needed to operate OpenFrame, OpenStudio provides a Java Eclipse Rich Client based console. Users can manage the system from the comfort of a familiar environment through a user-friendly-designed UI, even when they do not have sufficient knowledge of the UNIX operating system or OpenFrame.<br />

'''TACF authentication:'''

If the authentication type within the common.properties file is set up as TACF, authentication

function can be interlocked with OpenFrame’s own TACF to authenticate users and resources.

In this case, user permissions are controlled by the TACF manager allowing a high degree

of flexibility in user management policies.<br />

'''Built-in database support:'''

If the user-processed information needs to be recorded, OpenStudio uses "HSQLDB" internally

to store them (e.g. DEV module's compilation information for each project and DEP module's

request deployment information, etc.).

Databases other than HSQLDB are also compatible through the db.properties file.<br />

'''Automatic update:'''

When multiple users login, the updated modules are downloaded automatically, without user

input required, maintaining the latest modules allowing easy roll-out of patches and new

features.<br />

'''Failover and load balancing:'''

OSM manages the master and agent directly, providing load balancing for multiple connections

and a failover mechanism in case of server error.<br />

TmaxSoft provides a timeline of typically less than one year for a complete transition.

OpenFrame also provides a [[COBOL| COBOL Compiler]] which is compliant with [[COBOL85|COBOL85]] standard and IBM Extension language specifications and supports VSCOBOLII and MFCOBOL dialects<br />

TmaxSoft also asserts the benefits of OpenFrame include a lower [[total cost of ownership]] compared to maintaining a physical mainframe.
