Re: extracting selective information
Jothish, If all that's needed is a read-only snapshot of the data from the non-Oracle sources, then the heterogeneous services should be sufficient (more sophisticated usage might require the gateway product for that specific db). This is discussed in the Distributed Database Systems manual. Also see Notes 115098.1 (Unix) and 114820.1 (NT). HTH, -- Anita --- K.

TIA, Jothish Jotish, Snapshots are of course proprietary but nothing prevents you from using the same mechanism as 'snapshot refresh' - having a log which holds the primary key and enough information to reconstruct the insert, update or delete statement, and triggers to fill it. It's exactly the way that the Sybase replication agent for Oracle works - the log is then processed by a replication server. -- Regards, Stephane Faroult Oriole Corporation Voice: +44 (0) 7050-696-269 Fax:+44 (0) 7050-696-449 Performance Tools Free Scripts -- http://www.oriole.com, designed by Oracle DBAs for Oracle DBAs -- -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Stephane Faroult INET: [EMAIL PROTECTED] Fat City Network Services-- (858) 538-5051 FAX: (858) 538-5051 San Diego, California-- Public Internet access / Mailing Lists To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
