Installing and Updating the OVO Configuration on the Managed Nodes
Selective Distribution of User-selected Files to Managed Nodes
210
A configuration file seldist is provided in which node group names
together with file name prefixes and files are listed. For details about
seldist configuration file, see “The seldist Configuration File” on
page 211.
The advantages of this distribution include the reduction of the
following:
❏ disk space utilization on managed nodes
❏ network traffic during configuration file distribution
If selective distribution is not enabled, the standard distribution of
user-selected files is performed.
How Does Selective Distribution Work?
On starting configuration file distribution from the OVO GUI or
command line, the distribution manager (opcdistm) checks the selective
distribution configuration and when the distribution process of actions,
commands or monitors is started, Selective Distribution in accordance
with the requirements of the seldist file is started.
On distribution, every file from the customer actions|cmds|monitor
directories is compared against each file name prefix in the seldist file.
If it does not match any prefix, it is distributed to all agents of the
respective platform.
If it matches one or more entries, it is only distributed to the agents of
the corresponding node group(s). For example, an empty seldist file
would result in all files being distributed to all nodes.
In a MoM environment, you must manually ensure synchronization of
the seldist files on all of your OVO management servers.
Most Database SPI files have a dbspi prefix, SAP SPI files have an r3
prefix, so an example of a SAP SPI binary would be named r3perfmon.
In addition to the preconfigured SPI-related files, you may also add your
own files and file prefixes together with a node group name. This is most
useful if you have your own templates and accompanying scripts that
only need to be distributed to a subset of the nodes. For more
information, see the section “To Configure Custom Selective
Distribution” on page 217.
