50Picture Perfect 4.6 Enterprise EditionUser ManualConfigurationThe refresh program knows what databases are in the network and where they are located.The refresh_config table contains an entry for each history table to be refreshed on eachsubhost. The entries are created automatically whenever a subhost is defined using theControl/Hosts form. This table is for internal use by the refresh programs and is not accessible froma user interface. You do not need to change it.Table 4.Refresh Configuration TableColumn Name Type Descriptionid integer Unique row idhost_id integer Foreign Key - host tabletable_name varchar(19) table to be refreshedpoll_interval integer seconds to waitlast_poll_date integer yyyymmdd used for non-history refreshlast_poll_time integer hhmmss used for non-history refreshcurrent_id integer history subhost idmodify_datemodify_timeinteger yyyymmddinteger hhmmssRemote database access configurationThe hostname in the host table allows up to 64 alphanumeric characters. The hostname in the hosttable and the DBSERVERNAME in the Informix config file $INFORMIXDIR/etc/onconfig and the $INFORMIXDIR/etc/sqlhosts file must be identical. You do not need to edit onconfig orsqlhosts. Data is automatically written to these files during the Picture Perfect installation. It is forinformation purposes only.Polling intervalThe word “poll” refers to detecting changes between the nethost and the subhosts. Every machine inthe host table is polled for database refresh data based on a configurable time interval in therefresh_config table. Polling is configured only for history tables. The refresher executes for eachsubhost in the network, then sleeps for the poll interval and then begins again. Only subhosts thatare set up in the nethost with configure_online = ‘Y’ are refreshed.Note: Global tables other than history tables are immediately refreshed by Informix ER and do notuse poll interval times.Log file message layoutThe refresher log file is /cas/log/rfs.. Each entry indicates which table it is refreshingon the subhost as needed. Informix SQL and ISAM error codes are used for logging error messagesinstead of the full Informix textual error message.
