Well along with "liking to know" how to fix the problem, which evidently we won't know unless or until the exact same symptoms appear on our systems and Oracle Support divulges the information then, I'd also like to know what caused the problems and what exactly the symptoms were. Just a "slow" database is rather vague. Were their consistent messages in the alert log that pointed to something, or was everything acting like 10x more users than normal were accessing the system, or what. Knowing what caused the problem as well would be beneficial, in case the same sort of process (or processes) were taken here. I've only done an "upgrade" once, usually I prefer to always do a clean install and then export from the old version and import into the new version, just so everything stays as "clean" as possible, but if this was done at Cingular, did anybody have any ideas on how the corruption occured in the first place? -- -- Bill Ferguson
