Issue with 2k and 4k db_block_size – ORA-1450 when upgrading to Oracle 12.2.0.1

The text on the OTN page is a bit misleading – and a customer I work with downloaded the wrong version which led to a failed upgrade – even though the scripts seem to be made for this patch upgrade.… [Read More]

OPTIMIZER_ADAPTIVE_FEATURES obsolete in Oracle 12.2

The Oracle Database 12.1 parameter OPTIMIZER_ADAPTIVE_FEATURES has been made OBSOLETE (i.e. must be removed from the SPFILE when upgrading) in Oracle Database 12.2.

  • OPTIMIZER_ADAPTIVE_STATISTICS=FALSE by default

Nigel Bayliss, our “Optimizer” Product Manager has blogged about it already with way more detailed insights.… [Read More]
