Table A.2 Log Directories
Directory Name Definition
$HORCM LOG A directory specified using the environmental variable HORCM_LOG. The HORCM log file, trace file, and
core file as well as the command trace file and core file are stored in this directory. If no environmental
variable is specified, “/HORCM/log/curlog” is used.
$HORCC LOG A directory specified using the environmental variable HORCC_LOG. The command log file is stored in
this directory. If no environmental variable is specified, the directory “/HORCM/log*” is used (* is the
instance number). While the HORCM is running, the log files are stored in the $HORCM_LOG directory
shown in (a). When the HORCM starts up, the log files created in the operation are stored automatically in
the $HORCM_LOGS directory shown in (b).
a. HORCM log file directory in operation
$HORCM_LOG = /HORCM/log*/curlog (* is instance number)
b. HORCM log file directory for automatic storing
$HORCM_LOGS = /HORCM/log*/tmplog (* is instance number)
A.2 Trace Files
The command trace file is used for maintenance aiming at troubleshooting. It is not created
normally. If a cause of an error cannot be identified using the log file, the environmental
variables or trace control commands with trace control parameters are issued to start
tracing and the trace file is created. The trace control parameters include trace level, file
size, mode, etc. More detailed tracing is enabled by increasing the trace level. Tracing is
made in wraparound within the range of the file size. HORCM makes the trace file according
to the trace level specified in the HORCM start-up shell script set to activate the HORCM.
A.3 Trace Control Command
The trace control command (one of the HORCM control commands) sets or changes the trace
control parameters. This command is used for troubleshooting and maintenance. If no trace
control parameters can be specified using the environmental variables in the user’s
command execution environment, it is possible to change the trace control parameters into
the global parameters using this command. Table A.3 lists and describes the parameters of
the trace con
trol command.
Table A.3 Trace Command Parameters
Parameter Function
Trace level parameter Specifies the trace level, range = 0 to 15.
Trace size parameter Specifies the trace file size in KB.
Trace mode parameter Specifies the buffer mode or non-buffer mode for writing data in the trace file.
Trace type parameter Specifies the trace type defined internally.
Trace change instruction Specifies either the command or the HORCM (CCI instance) for which the trace control
parameters are changed.
