Background technique

At present, the key business systems in many industries use IBM mainframe mainframe systems. Mainframe (MAINFRAME) is the corresponding noun that appeared after the appearance of mini computers (MINI COMPUTER) such as DEC PDP-8 in 1970. It originally refers to It is a large computer that can be managed in a centralized manner, occupies a large area, is expensive, but is very reliable. It relies on RAS (Reliability, Availability, Serviceability) - high reliability, high availability, and high serviceability, which will be valued by many customers who pay attention to these three aspects. However, due to the performance and high availability of open platforms, especially minicomputers, are becoming more and more The higher the cost, coupled with business flexibility and cost, more and more customers will choose to migrate their business systems to the open platform. Based on the TCP/IP protocol, the open platform can build the customer's IT system architecture in a more free way, and can adapt to the new application mode in a timely manner by choosing different configurations for different application environments. The host environment is more open, allowing users to use it more actively in terms of technical and economic costs.

Therefore, there is an urgent need to provide a platform architecture application solution that can reduce the hardware cost of the architecture itself while ensuring that the entire application architecture can meet its original requirements of high reliability, high availability, and high serviceability.

detailed description

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Fig. 1 shows the processing flowchart of the development platform application method of Embodiment 1 of the present invention, comprising the following steps:

Step 102: Use a general server or a small host as the main body of the server in the business system.

Step 104: Realize the application program and data storage in the server main body by using the simulation middleware on the development platform.

Based on the idea of software architecture replication, realize the CICS function and VASM management function of the mainframe environment through simulation software, split the tightly coupled architecture of the mainframe, and cooperate with the server cluster mode of the open platform to realize hardware support. This can not only smoothly migrate mainframe applications to open platforms, but also reduce the migration time period and technical continuity.

Further, using the UNIX-like system in the development platform as the operating system of the server main body;

The monitoring and automatic management module in the development platform is used as the management system in the business system.

Further, using the CICS middleware in the development platform to realize the data management module in the business system;

The transaction management module in the business system is realized by using the CICS middleware in the development platform.

The software architecture is used to simulate CICS functions and VASM management functions. The host platform application program relies on the file management mode of the host platform. The VASM function simulation software for simulating the host platform is developed on an open platform to facilitate the operation of the application program, and the middleware level simulation of software products is developed. Software, to realize the COBOL program of the host platform on the open platform, use the database software of the open platform to realize the data management and storage function, configure its disaster recovery management mechanism according to the customer environment, and the operating system of the open platform can support the monitoring and management function of the server , realize platform expansion and load balancing through the cluster function, and improve the high availability and high reliability of the overall framework.

Further, the application layer server cluster and the database server cluster in the server body are constructed by using general servers or small hosts.

Wherein, the server bodies are connected through TCP/IP.

Using a minicomputer as the main data processing server of the architecture can greatly improve the high availability and high reliability of the application architecture on the open platform, especially the application system in the data concentration mode. However, a data processing server using a general-purpose server as an architecture combined with database software can perform distributed data processing, which is usually implemented in applications that have low requirements for data consistency and timeliness. The choice of the two data modes can be selected according to specific applications.

The simulation module 204 is configured to use the simulation middleware on the development platform to realize the application program and data storage in the server main body.

Further, the general server or small host 202 uses the UNIX-like system in the development platform as the operating system of the server body, and uses the monitoring and automatic management module in the development platform as the management system in the business system .

Further, the simulation module 204 uses the CICS middleware in the development platform to realize the data management module in the business system, and uses the CICS middleware in the development platform to realize the transaction management module in the business system .

FIG. 3 is a schematic diagram of an open platform replacing a mainframe environment software environment system according to Embodiment 3 of the present invention.

As shown in Figure 3, the entire software of the IBM mainframe is systematic and is deployed on its Z series servers to realize its functions. As an alternative solution on the open platform, it needs to be split from the architecture, so the corresponding software system The interior of the architecture can be divided into several modules to facilitate the realization of functional modules on the open platform, and to ensure that even if the IBM mainframe is not used and the open platform server is used, there will be perfect function realization. In this embodiment, the entire mainframe software system is divided into 5 modules, from bottom to top and from left to right are:

1. Operating system (OS): IBM uses its Z/OS operating system to manage its mainframe servers, while the open platform will use a UNIX-like system to manage servers, and the operating system will conform to the security management model of the UNIX system.

2. System Management (System Management) is divided into monitoring and automation. IBM's built-in monitoring is the Tivil software management system. Automatic management is implemented with the help of multiple sensors inside the mainframe, such as internal storage backup and hardware downtime. Automatic switching, data backup switching, automatic switching of service nodes and other functions. The open platform launches a monitoring and automatic management module corresponding to its application architecture. The monitoring content includes storage devices, basic machine hardware operation of servers and switches, middleware operation on application servers, and database operation on database servers. Automatic downtime switching function configuration (for example, storage downtime automatic switching), background data backup and other management functions.

3. Database (DATABASE Manager): Use the data software commonly used on the open platform as the database management part of the entire software system. High availability implementation and performance load balancing processing need to be adjusted according to actual application needs. The simulated CICS middleware component simulates the function of the JES program on the mainframe and can execute the JOB program to achieve calling and monitoring by running batches.

4. Transaction Manager: The open platform simulates CICS components to realize the middleware function of CICS in the original mainframe and run its COBOL program or application development language developed by other programming languages, also supporting JAVA, COBOL, C/C++ Wait for the development environment on the original mainframe system environment.

5. Network Communication (Network Management): Support TCP/IP protocol for network interconnection, but considering that it may need to be interconnected with the mainframe environment, it can be compatible and support IBM's unique SNA protocol, and do it through IBM's open SNA protocol interface. Secondary product development and packaging can be interconnected with the IBM mainframe platform.

Usually the IBM mainframe uses 6 IBM Z series machines, two of which are used as couplers for clock synchronization and high data availability in the cluster environment, and 4 are used as computing nodes interconnected through couplers, using high-speed fiber optic connections in the middle, and external high-speed storage use. The entire architecture is called the Sysplex architecture, which is an architecture in which functional applications and databases are tightly coupled. To use a solution based on a minicomputer or a general-purpose server on an open platform, the split of the architecture functions must be considered first, and the split of the architecture must be ensured. It is logical and functionally compatible with the mainframe environment.

On the entire hardware open platform, it supports the smooth operation of the system after a single node fails. Divide the hardware environment into several modules:

1. The application layer server cluster is built with lightweight minicomputers or low-end general-purpose servers. It is easy to expand and virtualize using the Web and application layers. Nodes can be flexibly increased or decreased, and FAILOVER technology is used to ensure high availability and load balanced.

2. The database server cluster is built using high-end minicomputers or high-performance general-purpose servers. The data horizontal expansion of the database is realized through the cluster management function of the database software. The archiving and backup of business data and disaster recovery and emergency handling are carried out through the database's own functional tools or third-party Software Implementation.

3. The network is connected to the equipment, and the optical fiber switch is used between the servers to maximize the network transmission speed and ensure the operating efficiency of the system. The switch ensures its high availability in network interconnection through the active and standby redundancy mode.

4. External storage devices, use different types and performance storage according to needs, ensure storage I/O throughput, and make storage redundant backup, so that storage will not become the bottleneck of the entire system and ensure high availability.

This embodiment can simulate the running environment of a mainframe through the mode of architecture replication, and improve the high availability, high reliability and high performance of the overall architecture through cluster management and data management. Compared with the mainframe environment, it can effectively reduce the implementation period for customers to migrate from the mainframe environment to the open environment, and has a good continuity in technology, enabling the original technicians to maintain their original development experience on the mainframe platform.

Through the following schemes: use a general server or a small host as the server body in the business system, use the simulation middleware on the development platform to realize the application program and data storage in the server body, and use a general server or a minicomputer as the server of the entire application architecture The main body, the CICS simulation tool and the VASM simulation tool complete the realization of the application program function and file system reading in the mainframe environment. The servers are connected through TCP/IP without using IBM's SNA network protocol. From the perspective of application Directly process the application program, so as to get rid of the closeness of the mainframe platform, reduce the hardware cost of the architecture itself, and ensure that the entire application architecture can meet its original requirements of high reliability, high availability, and high serviceability.

For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
