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.
