Exadata Database Machine Host OS version-Alibaba Cloud Developer Community

A colleague asked me what operating system I used Exadata before? Earliest Oracle with HP cooperation Exadata V1 is used Oracle Enterprise Linux, And Oracle-Sun Exadata V2 The Current ALSO provides only OEL, but HAS adopted Solaris -11 Express in Exadata V2 on The TEST, therefore, Exadata V2 will soon have Solaris choices. Currently, most of the existing Exadata X2-2 and X2-8 use two small versions of OEL 5:
较早出厂的使用OEL 5.3
# cat /etc/enterprise-release
Enterprise Linux Enterprise Linux Server release 5.3 (Carthage)

近期出场的使用OEL 5.5

# cat /etc/enterprise-release
Enterprise Linux Enterprise Linux Server release 5.5 (Carthage)

# uname -a
Linux vrh1.us.oracle.com 2.6.18-128.1.16.0.1.el5 #1 SMP Tue x86_64 x86_64 x86_64 GNU/Linux

The IB should be one of the compatible cards specified in Note 888828.1 If you build a backup server machine it is best tro build as close a clone of the Exadata Compute nodes as you can get. I .e. install OEL 5 Update 5 and one of the IB cards specified in the note and you will have the correct ofed versions and kernel This will guarantee interoperabilty and correct operation with the kernel and ofed drivers From the doc InfiniBand OFED Software Exadata Storage Servers and database servers will interoperate with different InfiniBand OFED software versions, however, Oracle recommends that all versions be the same unless performing a rolling upgrade. Review Note 1262380.1 for database server software and firmware guidelines. InfiniBand HCA Exadata Storage Servers and database servers will interoperate with different InfiniBand host channel adapter (HCA) firmware versions, however, Oracle recommends that all versions be the same unless performing a rolling upgrade. Review Note 1262380.1 for database server software and firmware guidelines. For a complete list of the Oracle QDR Infinband adaptors see here: http://www.oracle.com/technetwork/documentation/oracle-net-sec-hw-190016.html#infinibandadp For the compute nodes all firmware updates must be done via the bundle patches descibed in Doc 888828.1 So I would advise upgrading to the latest supported bundel patch. For you backup server choose the same model card that came with the X2 compute nodes. Install Oracle Eterprise Linux Release 5 Update 5 Upgrade the firmware to the same firmware an on the X2 or higher if not already the same Database Machine and Exadata Storage Server 11g Release 2 (11.2) Supported Versions [ID 888828.1]
