Operating Notes for Large Systems
For operation using large systems, note the following points:
• To update the SSO repository information in the repository server (update system), check whether
operation stopped because of a problem such as the SSO repository being down in the repository
server (reference system). If the SSO repository is stopped, start it immediately.
• If the repository server (reference system) stays down for an extensive period of time, the data
integrity of the SSO repository may not be guaranteed. If irep15071 is output to the system log of
the repository server (update system), check the message contents and recover SSO repository
data. For details about messages output to the system log, refer to “Messages with Message
Number Beginning ‘irep’” in Messages.
If irep15071 is not output, restore the repository server (reference system). The update of the SSO
repository of the repository server (update system) is reflected in the SSO repository of the
repository server (reference system). The reflection is completed when the last update information
output to the access log of the SSO repository of the repository server (update system) is output to
the access log of the SSO repository of the repository server (reference system).
