CICS threadsafe commands in the APIIf your application program is defined as threadsafe, it can receive control on an open transaction environment (OTE) TCB.doi:dfhp4avM. Fisher
Beginning with IBM® CICS® Version 2, applications can run on TCBs apart from the QR TCB, which has positive implications for improving system throughput and for implementing new technologies inside of CICS. Examples of implementing new technologies
In the CICS open transaction environment (OTE), when application programs, task-related user exits (TRUEs), global user exit programs, and user-replaceable modules are defined to CICS as threadsafe, they can run concurrently on open TCBs.Margaret Fisher...
When developing application programs, you must be aware of certain programming considerations in order to improve the performance of your application and avoid potential problems. Whether you use qualified or unqualified SQL influences many other aspects of the CICS DB2 environment. To gain the ...
If you are using CICS intercommunication to make requests for functions or programs to run in remote CICS systems, choose IP interconnectivity (IPIC) over TCP/IP connections between the CICS systems to provide optimal support for threadsafe applications. With IPIC connections, CICS uses an open TCB...
如果您将 CICS® 程序编写并定义为线程安全程序,那么它可以接收对开放式事务环境 (OTE) 的控制 TCB。 要从OTE 获取最大性能优势,请以线程安全的方式编写 CICS 程序,以避免 CICS 必须切换 TCB。 但是,请注意并非所有 EXEC CICS 命令都是线程安全的,发出任何非线程安全命令都会导致 CICS 将任务切换回 QR TCB ...
Threadsafe API and SPI commandsdoi:threadsafeMany new system programming interface (SPI) commands in CICS Transaction Server for z/OS, Version 4 Release 2 are threadsafe. Additionally, some existing commands have been made threadsafe in this release.Alyn Iorwerth...
