Which Z OS component manages communications between applications in a Parallel Sysplex?
Cross-system Coupling Facility
In IBM mainframes, a Cross-system Coupling Facility, or XCF, is a component of z/OS that manages communications between applications in a sysplex.
What are the three methods of entering TSO commands?
You can enter most TSO commands, CLISTs, and REXX EXECs from all three panel types: data entry; menu; and scrollable data display. However, some TSO commands, such as LOGON and LOGOFF, can cause unwanted results when you enter them from ISPF.
What is the difference between Sysplex and Parallel Sysplex?
A sysplex can be either basic or parallel. A basic sysplex can communicate using channel to channel (CTC) connections between LPARs. Parallel Sysplex uses something called a Coupling Facility (CF). Note: The Parallel Sysplex Coupling Facility can run either as a separate LPAR or within a dedicated hardware device.
What is Parallel Sysplex in mainframe?
In computing, a Parallel Sysplex is a cluster of IBM mainframes acting together as a single system image with z/OS. Used for disaster recovery, Parallel Sysplex combines data sharing and parallel computing to allow a cluster of up to 32 systems to share a workload for high performance and high availability.
What is difference between TSO and ISPF?
TSO provides a single-user logon capability and a basic command prompt interface to z/OS. What is ISPF? ISPF is a full panel application navigated by keyboard. ISPF includes a text editor and browser, and functions for locating and listing files and performing other utility functions.
What is TSO command in mainframe?
Time Sharing Option/Extensions (TSO/E) allows users to create an interactive session with the z/OS® system. TSO provides a single-user logon capability and a basic command prompt interface to z/OS.
What is IBM z OS connect?
The IBM® z/OS® Connect offering is a Liberty feature that encapsulates calling z/OS target applications using REST (Representation State Transfer) calls. z/OS Connect is designed to provide a fast, secure, reliable connector to reach any z/OS asset.
What is ZOWE?
Zowe is an award-winning open source initiative within the Linux Foundation’s Open Mainframe Project (OMP). Founded by Broadcom, IBM and Rocket Software, Zowe is the first open source project based on z/OS.
What are the differences between Gdps and Gdps Xrc?
GDPS Metro Global – GM: This is a configuration for systems with more than two systems/sites, for purposes of disaster recovery. It is based on GDPS Metro together with GDPS Global – GM. GDPS Metro Global – XRC: This is a configuration for systems with more than two systems/sites for purposes of disaster recovery.
What is coupling facility in db2?
A coupling facility enables software on different systems in the Parallel Sysplex® to share data with the assurance that the data will not be corrupted and will be consistent among all sharing users. To share data, systems must have connectivity to the coupling facility through coupling-facility links.
What is the difference between a Sysplex and Parallel Sysplex?
What is Z OS Connect API?
The z/OS Connect API toolkit is an Eclipse-based workstation tool that you install into IBM Explorer for z/OS to create services and REST APIs for accessing z/OS resources.
Which Java API is required for Z OS?
The z/OS Connect API toolkit, the Eclipse-based workstation tool for creating APIs, requires IBM Explorer for z/OS Aqua V3. 1 and JRE V8. 0 or later. The z/OS Connect build toolkit requires JRE V8.
How to display proclib concatenations in JES2?
To display PROCLIB concatenations. $D PROCLIB (xxxxxxxx) displays dynamic PROCLIBs and PROCLIBs defined in the JES2 start PROC. Specifies the 1- to 8- character PROCLIB DD name being displayed.
What is the difference between z/OS and z/VSE and commands?
Please let me know the Difference between Z/OS and Z/VSE and Commands. They are completely different operating environments (operating systems) with different “commands”. The biggest similarities are that both are from IBM and both share most of the 360/370 assembler instructions.
What is JES2 start proc for proclib?
For PROCLIBs in the JES2 start PROC, this displays the approximate time that JES2 started. Can be used to select which PROCLIB concatenation to display. Displays the real DD name that is associated with this PROCLIB concatenation.
When is a proclib in use?
A PROCLIB is considered in use if a conversion processor currently has the data set open. Specifies a 1 to 6 character volume serial number for the PROCLIBs to be displayed. This command requires display authority.
