IBM Debug for z/OS details

Deep and wide z/OS environment support

Provides extensive subsystem support including environments such as Batch, CICS®, IMS, Db2®, z/OS Unix and TSO -- for day one support of the latest hardware, compilers, z/OS, CICS, IMS, Db2 and batch. This includes the ability to debug 64 bit applications and modules optimized with IBM Automatic Binary Optimizer for z/OS.

Code coverage to measure testing

Learn about the Debug Tool Code Coverage

Offers both client initiated and automated (headless) code coverage collection and the ability to view and combine code coverage results.

Valuable data at your fingertips

Learn about Debug Tool variables

Monitor variables, registers, memory and expressions.

Extensive debugging options

Set breakpoints at statements, programs and conditions, run until a breakpoint is reached, view and change the values of variables and storage and much more.

Boost your debug experience

Explore how to use Visual Debug (4:01)

For debugging using a traditional 3270 user interface, use IBM Debug for z/OS or IBM Developer for z/OS Enterprise Edition.

Visual debug, available through IBM Developer for z/OS, IBM Developer for z/OS Enterprise Edition, or IBM Wazi Developer, provides a graphical view of program execution flow, including the current execution path, plus features like setting breakpoints from the source editor. This extends the basic debugging with Eclipse IDE offered by IBM Debug for z/OS.

And if your chosen IDE is VS Code or Red Hat CodeReady Workspaces, for an OpenShift-native developer experience, Z Open Debug is provided with IBM Wazi Developer and IBM Developer for z/OS Enterprise Edition.

Supports shift-left testing initiatives

Measure the effectiveness of your automated testing by using code coverage in conjunction with IBM Z Virtual Test Platform or the ZUnit capability of IBM Developer for z/OS.

Simplify system test activities with IBM Debug for z/OS or IBM Developer for z/OS Enterprise Edition used in conjunction with the Rational Integration Tester beta to enable virtualization of Db2 calls.

Gain agility and flexibility

IBM flexible payment plans help align infrastructure investments with workload needs.
