LDF4_FILE_NAME (Parameter)

System Parameter Reference

Parameter: LDF4_FILE_NAME

Definition

The file path, name, and extension of the files in destination fileset #4

Description and Use

This parameter defines the file name template of the file #4 logging destination.

Some variables can be used in the file name template:

@INSTANCE_ID@: the SAP Convergent Charging Core instance identifier (Example: updater#1, rater#2 ...)
@INSTANCE_TYPE@: the SAP Convergent Charging Core instance type (Example: updater, rater ...)
@IP_ADDRESS@: the SAP Convergent Charging Core instance network IP address
@CURRENT_DATE@: the current date at the time the system is started
/: the local file name separator
%h: the home directory, the value of the system property 'user.home'
%t: the system temporary directory, the value of the system property: 'java.io.tmpdir'. Normally, it is "C:\temp". Therefore:"C:\temp\trace.log" == "%t/trace.log"
%u: a unique number to make the file name unique, as a GUID. To make sure that no naming conflict will occur.
%%: the percentage sign
%g: the sequence number of the file. This is useful only when you specify the file size limit and the maximum number count to do rotation. By default, this will be appended to the end of the filename/file pattern specified. For example:"%t/trace.%g.log" ----> "C:\temp\trace.0.log". By default: "C:\temp\trace.log.0"

SAP recommends that you end a log file with an extension '.log' and a trace file with an extension '.trc'.

Caution

If no value is set for this parameter, the value of the "ld.file4.name" system property located in the startup configuration file (jstart.config) of the instance is used instead.
If this system property is not set, the "" value is used instead.

Additional Information

See the LDF1_ENABLED and LDF2_ENABLED system parameters for more information about the configuration of the log and trace functions in the SAP CC system.
