Reconfiguring an FCC

There are three ways to reconfigure an FMS client cache (FCC). Each method involves a different level of user interaction and a different set of restrictions. Automatic reconfiguration of the FCC Automatic reconfiguration of the FCC occurs when changes are made to the fmsmaster_fscid.xml file and the primary FMS file server cache (FSC) configuration server is reconfigured. Not all FCC changes are reconfigured automatically. Many changes to FMS client cache (FCC) elements are automatically propagated to the FCC when you reconfigure the FMS primary configuration file (fmsmaster_fscid.xml). For example, the FCC detects when changes are made to the following FCCDefault parameters in the primary configuration file and reconfigures itself accordingly, without interrupting FCC client application service: FCC_TransientFileFSCSource FCC_EnableDirectFSCRouting FCC_WanThreshold FCC_MaxWANSources FCC_FSCConnectionRetryInterval The FCC also detects when changes are made to the following FCC configuration elements in the primary configuration file and reconfigures itself accordingly, without interrupting FCC client application service: FCCDefaultssite parentfsc assignment assignedfsc elements within the clientmap element directfscroute elements generated by the parentfsc file from resource elements in the primary configuration file directtransientvolume elements generated by the parentfsc file from resource elements in the primary configuration file Manual reconfiguration of the FCC Manual reconfiguration of the FCC is required when changes are made to the local fcc.xml file when the FCC is processing commands for one or more applications. The FMS client cache (FCC) responds to reconfiguration requests made through the fccstat utility, attempting to reconfigure without loss of service to the client workstation or to applications connected to the FCC. However, there are situations in which the FCC cannot be reconfigured automatically. Changes made in the local fcc.xml file while the FCC is processing commands for one or more applications require a manual FCC reconfiguration. Run the fccstat utility with the -reconfig argument. Changes are applied from your local fcc.xml files and from any parentfsc configurations. Restart the FCC Restarting the FCC is required when an immutable parameter (such as cache size) is changed in the fmsmaster_fscid.xml file or the fcc.xml file. Clients receive changes to immutable parameters when their FCCs are restarted.
