The individual Components The Archiving Monitor
3.1.1 Starting and Ending the Archiving Monitor
A control program start_amon.sh is provided in the directory ${NSR_INST}/ora-
cle/bin for coordinating the activities of the archiving monitor. This program can
be invoked at operating system level with the relevant parameters (start, status,
stop).
start_amon.sh [-t {nsr|emc}] <command> [<ORACLE_SID> ...]
The -t option is required if NSR-ORA (nsr) and NSR-ORA-EMC (emc) are
installed on one machine, so that it is possible to distinguish which archiving
monitor is to be started.
If ORACLE_SID is not specified, the environment variable $ORACLE_SID is eval-
uated. If this variable is not set, amon is started for all configured ORACLE
instances; otherwise only for the specified ORACLE_SIDs.
The following commands are available:
start Starts the archiving monitor
stop Stops the archiving monito r
status Status inquiry
The start command is used to start the archiving monitor. This requires the
database to be in ARCHIVELOG mode.
The configuration file dbo${ORACLE_SID}.init is then read out and the archiving
monitor (amon daemon) is started. All important events are recorded in a
protocol file located in the directory ${DBO_CONFIG_DIRECTORY}/prot.
The stop command deactivates the archiving monitor.
The status check status shows, among other things, the following information:
●the time the archiving monitor is activated
●the database to be monitored
●the archive directory
●the maximum number of offline redolog files
●the current number of offline redolog files
Example:
The following entries are assumed in the configuration file in this example:
NSR_SERVER=psi
DBO_CONFIG_DIRECTORY=/nsr/oracle/ora
