SET PROCESS
The SET PROCESS command changes the current SDA process context to that
of the process indicated by name or /INDEX=nn. The process specified by this
command becomes the current process for SDA until you exit SDA or change SDA
process context by issuing one of the following commands:
SET PROCESS/INDEX=nn
SET PROCESS process-name
SHOW PROCESS/INDEX=nn
In the analysis of a crash dump from a multiprocessing system, changing process
context can involve a switch of CPU context as well. For instance, if you issue a
SET PROCESS command for a process that is current on another CPU, SDA will
automatically change its CPU context to that of the CPU on which that process is
current. The following commands can have this effect if process-name or index
number (nn) refers to a current process:
SET PROCESS process-name
SET PROCESS/INDEX=nn
SHOW PROCESS process-name
SHOW PROCESS/INDEX=nn
See Section 4 for further discussion on the way in which SDA maintains its
context information.

The first SHOW PROCESS command shows the current process to be NETACP.
The SHOW SUMMARY command shows the names of the processes that exist.
