Output=log-filename.out
Output=log-filename_pid.out
Identifies the name of the file where you want the Hot Standby
software to create an operational output file (log) for the LCS
or LRS process:
o Specify the Output qualifier on the master database to create
an output file and collect information about the LCS process.
o Specify the Output qualifier on the standby database to create
an output file and collect information about the LRS process.
o Optionally, include "_PID" or "_pid" when you specify the
output file name. This causes the software to create a unique
file name because it includes the process identification (PID)
number.
Applicable to: Master and standby databases
Required or Optional: Optional
Default Value: None. If you do not specify the
Output qualifier, the Hot Standby
software does not record LCS or LRS
process activities to an output file.
The Output qualifier overrides definitions you make with the
BIND_LCS_OUTPUT_FILE or BIND_LRS_OUTPUT_FILE logical name. If you
enable replication operations for multiple databases, there will
be multiple operational output files.
The purpose of the operational log is to record the transmittal
and receipt of network messages, and to provide administrative
and diagnostic information.
Note the following when you specify the Output qualifier:
o You must specify an output file name. When you include "_PID"
in the output file specification, the command creates a unique
file name that includes the process identification (PID).
This command line creates a unique file name, for example,
DISK1:[USER]LRS_25C02914.OUT.
o Do not include a node name designation when you specify the
output file name.
o The default location is the database root file directory. You
can optionally include a directory name when you specify a
file name.
o The directory containing the output files must be readable and
writable by all processes.
o The default file type is .out
o You can display the name of output files that you specify with
the Output qualifier using the RMU Show Users command (shown
in Example 7-1). Output file names are not displayed in Show
Users output for files specified with a logical name.
NOTE
All bugcheck dumps are written to a corresponding
bugcheck dump file. Bugcheck dumps are not written to
the Output operational log.
Although it is optional, Oracle Corporation recommends that
you use the Output qualifier, or a logical name, to collect
information about the LCS and LRS processes during replication.
You can also collect information about the ABS, ALS, DBR, and
AIJSERVER processes by defining a logical name. The following
table lists the logical names you can define to collect server
process information to an output file:
Logical Name Specifies an output file for the . . .
BIND_ABS_LOG_FILE ABS process
BIND_ALS_OUTPUT_FILE ALS process (1)
BIND_DBR_LOG_FILE DBR process
BIND_HOT_OUTPUT_FILE AIJSERVER process
BIND_LCS_OUTPUT_FILE LCS process
BIND_LRS_OUTPUT_FILE LRS process
Footnote (1):
You can also collect information about the ALS process to an
output file by including the Output qualifier on the RMU Server
After_Journal command. For more information about displaying ALS
information, refer to the Oracle RMU Reference Manual.
Defining a logical name is also useful if you omitted the Output
qualifier when you entered the Replicate After_Journal Start
command to start replication. You can define a logical name to
specify an output file while replication operations are active.
This can be done by defining the appropriate logical name, and
then invoking the Replicate After_Journal Reopen_Output command.
This allows you to create an output file so the server can start
writing to the file without you having to stop and start the
server.
