CHAPTER 8 CONFIGURING EXADATAMachine. However, the version of OneCommand that came with your Exadata system only supportsautomatic installation of certain software versions and patches.The Exadata Owner’s Guide that came with your system specifies the RDBMS and GridInfrastructure installation media OneCommand needs for the installation. The patches and install mediarequired by OneCommand tends to change as new versions of OneCommand are released. Currently,the following media is required by OneCommand:• Oracle RDBMS & Grid Infrastructure 11.2.0.2 (patch 10098816)• p10098816_112020_Linux-x86-64_1of7.zip• p10098816_112020_Linux-x86-64_2of7.zip• p10098816_112020_Linux-x86-64_3of7.zipThe Readme file included within the onecommand directory states which bundle patches aresupported by the version of OneCommand installed on your system. For example, we recently installed aquarter rack X2-2 system in our lab. The following listing shows the patches supported by it in theReadme file:# egrep 'PATCHES|bundle patch' /opt/oracle.SupportTools/onecommand/READMEPATCHES Applied with this versionBug 10252487 - 11.2.0.2 db machine bundle patch 1Checking MOS note 888828.1, we see that Bundle Patch 1 for 11.2.0.2 is patch 10252487.• Bundle Patch 1 (patch 10252487)• p10252487_112020_Linux-x86-64.zipThe install media (zip files) listed above may already be installed on the first compute node of yourExadata Database Machine. So it’s worth a look, and it may save you some time to check beforedownloading the installation files. If necessary, download and stage the installation files in the/opt/oracle.SupportTools/onecommand directory on the first compute node.Step 7: Running OneCommandAlthough Exadata can be configured manually, OneCommand is the preferred method. OneCommand isan Oracle-provided utility consisting of several configuration steps, (31 as of this writing). OneCommandprovides two very important benefits to Exadata customers and Oracle’s support staff. First, it creates alimited number of standardized (and well known) configurations, which makes the platform mucheasier to support. After all, who wants to hear “oh, I’ve never seen it configured that way before” whenwe finally get a support tech on the phone? This is one of Exadata’s key strengths. Second, it provides asimplified and structured mechanism for configuring Exadata from start to finish. This means that withvery little knowledge of Exadata internals, an experienced technician can install and configure Exadatain a matter of hours. It’s unclear whether Oracle originally intended to provide support forOneCommand externally, but about the same time the X2 began shipping, Oracle added it to theExadata Owner’s Guide. The instructions in the Owner’s Guide are not very extensive, but the Readmeincluded with the utility does a fairly good job of explaining how to run it, and what to watch out for.OneCommand comes preinstalled in the /opt/oracle.SupportTools/onecommand directory on yourcompute nodes. If you need access to the latest version of OneCommand, it is available for downloadfrom Oracle’s Technology Network. The download link is password-protected however, and you willneed to open a service request with Oracle Support to request temporary access to download it.263
