Oracle: Unbreak my Linux Heart

Kevin Closson’s Oracle Blog has an interesting blog about Mount Options for Oracle over NFS . It's not as hard as it may seem, but you have to pay attention to the option you use when mounting the NFS share. There are also little differences between various ports of Oracle for certain platforms. This, of course, makes troubleshooting nearly impossible. Kevin sheds his idea of this too. He may blog about this later in more detail...

tech times' techbytes: Momentum continues for Oracle Unbreakable Linux support program : "Companies such as 170 Systems, AppWorx Corp., Egenera, EMC, Emulex Corp., Hitachi Data Systems, LSI, NetApp, Patchlink, Pillar Data Systems, QLogic, and Synoran, all members of the Oracle PartnerNetwork (OPN), now include Oracle Enterprise Linux among the operating systems they support. In addition, open source companies including KnowledgeTree and SugarCRM are also among those supporting the Oracle Unbreakable Linux Support Program. Partners are finding that they can easily and rapidly support their applications on Oracle Enterprise Linux because Oracle Enterprise Linux is fully compatible with Red Hat Enterprise Linux."

Today, Oracle announced a new TPC-C benchmark result on an HP ProLiant ML350 with the best ever price/performance. This result sets a world record in the price/performance category, which measures the cost per transaction of the configuration benchmarked. It demonstrates that Oracle Database not only provides customers with a highly performant and scalable data management solution, but can also deliver unparalleled cost savings with record-breaking performance on HP ProLiant systems, ideally suited to small and medium sized businesses (SMB). Achieving 100,926 transactions per minute with a price/performance of $.78/tpmC, Oracle Database 10g Release 2 Standard Edition One delivered 45 percent more performance at 14 percent less cost than its nearest competitor. To set this new TPC-C price performance record, Oracle Database 10g Release 2 Standard Edition One was run on an HP ProLiant ML350 server with one Intel Quad-Core Xeon 2.6 GHz processor and HP StorageWorks arrays. The operating s...

Had a discussion with an Oracle architect about increasing the shared memory limit of Linux for Oracle. Thought I'd blog this link to instructions on Tuning and Optimizing RHEL for Oracle 9i and 10g Databases . As OEL is very similar to RHEL 4, it should apply. As far as I know, you can increase the shared memory limit of Linux on a bare metal machine with 16GB RAM to a value higher than 4, 8 or even 12 GB. You only need the hugemem kernel if you have more than 16GB of RAM. And it will basically assign a separate chunk of 4GB to kernel space and the rest to user spaces...
