Making SQL Performance Solutions Stick - Followup #2

During last week's webinar, there were several questions that I did not have a chance to answer so I wanted to follow-up by answering those questions here. I also wanted to provide links to previous webinar recordings as many people had asked where to find them.

Do you need asmlib?

There are many questions from few of my clients about asmlib support in RHEL6, as they are gearing up to upgrade the database servers to RHEL6. There is a controversy about asmlib support in RHEL6.  As usual, I will only discuss technical details in this blog entry.

ASMLIB is applicable only to Linux platform and does not apply to any other platform.

Now, you might ask why bother and why not just use OEL and UK? Well, not every Linux server is used as a database server. In a typical company, there are hundreds of Linux servers and just few percent of those servers are used as Database servers. Linux system administrators prefer to keep one flavor of Linux distribution for management ease and so, asking clients to change the distribution from RHEL to OEL or OEL to RHEL is always not a viable option.

Do you need to use ASMLIB in Linux?

All about RAC and MTU with a video

Let’s first discuss how RAC traffic works before continuing. Environment for the discussion is: 2 node cluster with 8K database block size, UDP protocol is used for cache fusion. (BTW, UDP and RDS protocols are supported in UNIX platform; whereas Windows uses TCP protocol).

UDP protocol, fragmentation, and assembly

UDP Protocol is an higher level protocol stack, and it is implemented over IP Protocol ( UDP/IP). Cache Fusion uses UDP protocol to send packets over the wire (Exadata uses RDS protocol though).

Oracle’s Timeline, Copious Benchmarks And Internal Deployments Prove Exadata Is The Worlds First (Best?) OLTP Machine – Part 1.5

In Part I of this series about Oracle OLTP/ERP on Exadata versus non-Exadata, I took a moment to point out the inaccuracies of a particular piece of Oracle marketing literature. In a piece aimed at chronicling Oracle Corporation history, the marketing department went way out of line by making the following claim regarding Exadata:

[...] wins benchmarks against key competitors [..]
