Re: tough job to abandon Oracle DB
Last time I was at Unilever many years ago, and if you are selling databases is there a bigger consumer, they were migrating their entire database backend for their SAP systems off Oracle onto DB2 because Oracle had tried to milk them too hard. IBM were seriously sugaring the pill mind.
If you want to behave like Oracle you deserve to lose business.
Another company I worked for we resolved a million plus license liability to Oracle they had got themselves into. Zero help from Oracle to get them out of it.
Oracle are cunts. Avoid if possible.
