About Partitioning the Siebel File System
This topic describes how to perform the optional task of partitioning the Siebel File System.
This topic is part of Partitioning the Siebel File System.
Partitioning the Siebel File System allows you to store larger volumes of data on multiple devices. The original Siebel File System might use a single directory or might already use multiple directories on multiple devices or partitions.
In general, the term partitioning, as used in this
topic, refers to running the sfspartition utility,
which is provided for the purpose of adding one or more network directories
to an existing Siebel File System and distributing the existing files
among all of the participating directories. You can add each new directory
on the same device as an existing directory or add it on a different
device or partition in order to expand the overall capacity of the
Siebel File System. (You must consider the future growth of the volume
of data when you plan how to organize the file system directories.)
You can also use sfspartition to remove one or
more existing directories from service for the Siebel File System,
provided that the overall file system capacity remains sufficient.
To partition your Siebel File System, you first update the value of
the enterprise parameter Siebel File System (alias FileSystem) so
it specifies all of the network directories that you want to use for
the Siebel File System, delimited by commas. You then run the partitioning
utility and specify both the original directories containing the existing
files and the updated target directories, corresponding to the updated
FileSystem parameter value. The sfspartition utility distributes the
files in the Siebel File System evenly across the target directories.
The utility logs information into a file named sfspartition.log, which
is located in the log directory within the Siebel Server root directory.
When the File System Manager component (alias FSMSrvr) starts, it verifies the existence of all of the file system directories specified using the FileSystem parameter. When new file attachments are inserted, FSMSrvr distributes them across these directories. If a file system directory is unavailable, then FSMSrvr logs an error message in the FSMSrvr log file and tries to write the file attachment to the next available directory. If no file system directory is available, then FSMSrvr terminates and writes an error message to the FSMSrvr log file.
In order to maintain the even distribution of files across file system directories, you must run the partitioning utility every time that you update the value of the FileSystem parameter, for example, if you add or remove a file system directory. The procedure in this topic describes in detail how to perform this task.
Before you partition your Siebel File System, note the following additional deployment options:
Mobile Web Client. A Mobile Web Client's configuration file must refer to a single directory location, unless you configure it to use the server-based data source.
Replication Manager requirements. Partitioning is supported on replicated nodes. For more information about replication, see Siebel Remote and Replication Manager Administration Guide.
