Exadata用户的困境
当然这是Oracle-Sun Exadata V2 数据库一体机的竞争者,Netezza公司制作的一个小视频,但并非空穴来风!
很多人告诉我有了Exadata这么智能的一体机后都可以不需要dba了,那么这是事实吗?
就我个人的体验,部署了Exadata之后DBA花在管理上的时间更多了。
Exadata上复杂的数据库升级步骤:
Infiniband Switch - > Exadata Storage Software - > Exadata Host Minimal Patch -> Grid Infrastructure - > Database
客户视角的Exadata 详细升级过程:
- Exadata Cells from 11.2.1.3.1 to 11.2.2.2.0
- Exadata database nodes from 11.2.1.3.1 to 11.2.2.2.0
- Applying a number of pre and post patching fixes (addendums to the standard patching instructions,probably included due to customer reported issue with eth patching
- Upgrade kernel on database nodes
- Upgrade GI Home to 11.2.0.2
- Upgrade ALL RDBMS Homes to 11.2.0.2
- Upgrade the database to 11.2.0.2
- Apply 11.2.0.2 BP2 to ALL Homes(Part of this need to be done manually ,as opatch auto doesn't work when the installation has different GI and RDBMS owners)
- 软硬件一体,耦合过于紧密
- 升级操作十分复杂,客户看到升级流程后几乎绝望
- 国内使用经验贫乏
- support只有Oracle自己一家,没有第三方可选
- 就以往的表现来看美国支撑的X team并不给力。。。。。。
- 贵,Exadata很贵!具体了解其报价Exadata V2 Pricing
