h2 tags | My thoughts on Oracle Slow running RMAN compressed backup post changing compatible parameter from 12.1.0.2 to 19.0.0. Degraded DB performance with significant waits for “reliable messages” & “enq: KO – fast object checkpoint” DB startup taking significant time on newly installed 19c RAC cluster Shell script to create DDL for all non-default users/schemas in Oracle DB Things to consider when implementing/using Multi-Instance Redo Apply(MIRA). Aggressive DBWR/High write IO requests post DR switchover on 19c database. A day well spent @OCYATRA2022!!!! Resolving significant Enq: HW contention post 19c upgrade tfactl fails with error “Exception in thread “CommandLine” – unable to create manager” High “latch: shared pool” post 19C DB upgrade |
