Even though, this sounds trivial at first sight, unfortunately it isn’t. But a bug fix done recently for a German automotive customer is very handy here. So let me show you how you can Choose your desired time zone version (DST) upgrade.

Many thanks to a German customer for showing me this tiny behavior change with Oracle Database RU 19.4.0. From this RU on the well known ORA-1555 won’t get reported into alert.log anymore since 19.4.0. But if you still like to see the “snapshot too old” error, then you can use a workaround.

Posted on May 24, 2018 by Flaws and Pitfalls 5

RMAN backup generates traces in Oracle 12.2.0.1Oracle 12.2.0.1 seems to be the “tracing” release without further patch or parameter treatments. After posting about MMON unconditional traces in Oracle 12.2.0.1 a day ago, I received a couple of comments either on the blog, via LinkedIn or Twitter regarding other trace facilities in Oracle Database 12.2.0.1. One of them is the case that RMAN backup generates traces in Oracle 12.2.0.1.
