The individual Components

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 monitor
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

The following entries are assumed in the configuration file in this example:

NSR_SERVER=psi
DBO_CONFIG_DIRECTORY=/nsr/oracle/ora
