Additional region size required

Z Abend Investigator runs in the same region as your abending program at the time of the abend. Therefore, there must be spare GETMAIN storage that is not used by the application in order for Z Abend Investigator to run and analyze the program storage in its abend state. Initially, up to 16 megabytes of storage might be required, depending on the execution environment. This extra region size increases as the size and complexity of the abending program increases.

For detailed information about storage requirements, see Storage recommendations.

In situations where Z Abend Investigator is unable to obtain sufficient storage for the real-time analysis of a fault, a Recovery Fault Recording fault entry is normally created (see Recovery fault recording). However, if Recovery Fault Recording has not been enabled, then a SYSMDUMP can be taken for subsequent batch or interactive reanalysis.
