Gary Pugh, Oracle 9i product manager, confirmed that it has remarketed its migration programme since the deal. Financial incentives are on offer to Informix customers signing up for Oracle's Safeswitch migration programme.
"We have raised the awareness of Safeswitch following the IBM deal," said Pugh, who referred to the IBM purchase as "a wake-up call for the Informix user base".
Safeswitch was introduced by Oracle to assist businesses planning to move their underlying information infrastructures.
Oracle's action has prompted speculation about a database price war. "I think [IBM] is a serious threat to Oracle," said Charlie Garry, senior programme director for database research at Meta Group. Some industry insiders think IBM's DB2 database has overtaken Oracle as the market leader.
