USM driver install actions failed /u01/app/grid/11.2.0/perl/bin/perl -I/u01/app/grid/11.2.0/perl/lib -I/u01/app/grid/11.2.0/crs/install /u01/app/grid/11.2.0/crs/install/rootcrs.pl execution failed USM drivers […]

Setting up Oracle Clusterware 11.2.0.4 on SuSE Linux Enterprise Server (SLES) SP2 should work flawlessly, but sometimes it does not. 🙂 It turned out that this would become a pair of blog entries.

Oracle on AIX: How to find out the process memory usage
Calculating memory on Unix is tricky business. Especially when a complex software like Oracle Database has shared memory segments like SGA and Code Area. One might be convinced to use the following construction to calculate the overall memory footprint of Oracle processes running on this machine: ps -elf |egrep ” oracle* | ora_.*_* ” | […]

How to move a datafile as Oracle Managed File (OMF) before and after
Sometimes, you just have to move your data files away from where they sit. But when you love Oracle Managed Files as I do, you may want to have it being an OMF afterwards as well as before. Doing it the way you would have done it with ASM, fails. (RMAN> copy datafile 10 to […]
