haemtrcoff Command
Purpose
Turns tracing off for the Event Manager daemon.
Syntax
haemtrcoff -s subsys_name -a trace_list
Description
The haemtrcoff command is used to turn tracing off for specified activities
of the Event Manager daemon. Trace output is placed in an Event Management
trace log for the system partition.
Flags
- -s subsys_name
- Specifies the name of the Event Management subsystem. On a node this
is emsvcs. This argument must be specified.
- -a trace_list
- Specifies a list of trace arguments. Each argument specifies the type
of activity for which tracing is to be turned off. At least one argument must
be specified. If more than one argument is specified, the arguments must be
separated by commas. The list may not include blanks.
Parameters
The following trace arguments can be specified:
- init
- Stops tracing the initialization of the Event Manager daemon.
- config
- Stops dumping information from the configuration file.
- insts
- Stops tracing resource variable instances that are handled by the daemon.
- rmctrl
- Stops tracing Resource Monitor control.
- cci
- Stops tracing the client communication (internal) interface.
- emp
- Stops tracing the event manager protocol.
- obsv
- Stops tracing resource variable observations.
- evgn
- Stops tracing event generation and notification.
- reg
- Stops tracing event registration and unregistration.
- pci
- Stops tracing the peer communication (internal) interface.
- msgs
- Stops tracing all messages that come to and are issued from the daemon.
- query
- Stops tracing queries that are handled by the daemon.
- gsi
- Stops tracing the Group Services (internal) interface.
- eval
- Stops tracing expression evaluation.
- rdi
- Stops tracing the reliable daemon (internal) interface.
- sched
- Stops tracing the internal scheduler.
- shm
- Stops tracing shared memory management activity.
- all
- Stops tracing all activities.
- all_but_msgs
- Stops tracing all activities except for messages. Message activity is
defined by the msgs argument.
Security
You must have root privilege and write access to the SDR to run this command.
You should be running on the control workstation. Before running this command,
you must set the SP_NAME environment variable to the appropriate system partition
name.
Exit Status
- 0
- Indicates the successful completion of the command.
- 1
- Indicates that an error occurred. It is accompanied by one or more error
messages that indicate the cause of the error.
Restrictions
Do not use this command during normal operation. Use this command only
under the direction of the IBM Support Center. It provides information for
debugging purposes and may degrade the performance of the event management
subsystem or anything else that is running in the system partition.
Standard Output
When the command executes successfully, it writes the following informational
messages:
Reading Event Management data for partition syspar_name
CDB=new_EMCDB_file_name Version=EMCDB_version_string
Standard Error
This command writes error messages (as necessary) to standard error.
Examples
- To turn off all tracing for the Event Management subsystem on one of the
cluster nodes, log in to the node and enter:
haemtrcoff -s emsvcs -a all
- To turn off all tracing of initialization and configuration for the Event
Management subsystem on a cluster node, log in to the node and enter:
haemtrcoff -s emsvcs -a init,config
