SVC dumps

A SVC dump is a core dump initiated by the operating system generally when a programming exception occurs. SVC dump processing stores data in dump data sets that you pre-allocate, or that the system allocates automatically as needed.

Alternatively, you can initiate an SVC dump through the MVS console, to gather diagnostic data for a 'hang' condition, for example. SVC dumps that you initiate this way are called console dumps.

One example of an abend that could occur is the EC3 abend. WebSphere® Application Server for z/OS® requests an SVC dump when a controller terminates a servant (region) with an EC3 abend when timeout conditions occur. See z/OS MVS Diagnosis: Tools and Service Aids, GA22-7589 for additional information about SVC dumps.
