Oracle Doesn’t Look Good – 23ai TBA

I have to say that Oracle Corporation is not looking like a company that knows what its doing. At least when it comes to getting Oracle 23ai shipped out the door for on-premise customers. The saga continues and no mention from Oracle why the continued delays. If I’m an Oracle Cloud customer, I can enjoy …

I am patching an Oracle Multitenant 19.13 database with the April 2022 RU which will bring my database version up to 19.15 (yes I skipped 19.14). When running datapatch against the PDBs, I received the following error stack for every PDB: Patch 33806152 apply (pdb TST): WITH ERRORS logfile: /u01/app/oracle/cfgtoollogs/sqlpatch/33806152/24713297/33806152_apply_ORCL_TST_2022May14_00_47_11.log (errors) -> Error at line …

GTT Table Stats and SYS.WRI$_OPTSTAT_TAB_HISTORY

Back in 2015, I upgraded our Oracle 11.2.0.4 databases to 12.1.0.2 and experienced some performance issues related to our use of GTTs. I blogged about those issues here. The crux of the issue I was trying to solve was that a behavior change in 12c lead to Oracle saving stats that the GTT has zero …

ORA-1114 Running Datapatch

I have an Oracle 19.3 Multitenant database that I am attempting to apply the 19.7 Release Update. The RU was installed by opatch just fine. But datapatch will incur the ORA-1114 error. I get errors like the following in one of the logs: SQL> alter pluggable database GOLD2020_06_18_123653 open read write instances=all;alter pluggable database GOLD2020_06_18_123653 …

It’s In The Details

I have an Oracle 12.1.0.2 Multitenant database that I’m trying to remove a PDB from. However, I mistakenly removed the storage from the database server and the PDB cannot access its files. When unplugging the PDB, I get the following error: SQL> alter pluggable database GOLD2019_08_22_125953 unplug into ‘/tmp/GOLD2019_08_22_125953.xml’; alter pluggable database GOLD2019_08_22_125953 unplug into …
