IH Command (TNS/R Native and OSS
Processes)
The IH command displays information about signal handling for all signals or for a
specified signal. The form of the IH command is:
signal-name
specifies a signal for which signal-handling information is to be displayed. The
TNS/R native signals are:
{ SIGSEGV | SIGILL | SIGFPE | SIGABRT }
{ SIGSTK | SIGLIMIT | SIGMEMMGR | SIGNOMEM }
{ SIGMEMERR | SIGTIMEOUT }
Additional signals are supported by Open System Services (see Considerations
below). If signal-name is not specified, information is displayed for all signals,
including both TNS/R native signals and OSS signals.
Considerations
•
Because only TNS/R native or OSS processes can have signal handlers, the IH
command is allowed only on such processes. For more information on signals,
refer to the description of the SIGACTION_INIT_ procedure in the Guardian
Procedure Calls Reference Manual.
•
Open System Services supports additional signals that can be specified for
signal-name. For more information about OSS signals, OSS users can refer to
the signal(4) topic in the reference page, either online or in the Open System
Services System Calls Reference Manual.
•
The first column of the IH command display shows the name of each signal for
which information is provided.
