Replicating Oracle Webinar Question Follow-up

We had really great webinar on Replicating to/from Oracle earliest this month, and you can view the recording of that Webinar here.

A good sign of how great a Webinar was is the questions that come afterwards, and we didn’t get through them all. so here are all the questions and answers for the entire webinar.

Q: What is the overhead of Replicator on source database with asynchronous CDC?

A: With asynchronous operation there is no substantial CPU overhead (as with synchronous), but the amount of generated redo logs becomes bigger requiring more disk space and better log management to ensure that the space is used effectively.

Q: Do you support migration from Solaris/Oracle to Linux/Oracle?

A: The replication is not certified for use on Solaris, however, it is possible to …

A New Home for Tungsten in the UK

I was suitably heartened to hear about the new mine opening up in the Devon here in the UK to mine the element Tungsten.

I comment on this to my associates at Continuent, where comments were made by Csaba as to the appropriate quotes in the article:

“Tungsten is an extraordinary metal.”

“It’s almost as hard as a diamond and has one of the highest melting points of any mineral.”

“Adding a small amount to steel makes it far harder, far more resistant to stress and heat. The benefits to industry are obvious.”

Leading to him to suggest Adding a small amount of Tungsten to MySQL makes it far harder, far more resistant to stress and failures. The benefits to industry are obvious.

I couldn’t possibly agree more!

Revisiting ZFS and MySQL

While at Percona Live this year I was reminded about ZFS and running MySQL on top of a ZFS-based storage platform.

Now I’m a big fan of ZFS (although sadly I don’t get to use it as much as I used to after I shutdown my home server farm), and I did a lot of different testing back while at MySQL to ensure that MySQL, InnoDB and ZFS worked correctly together.

Of course today we have a completely new range of ZFS compatible environments, not least of which are FreeBSD and ZFS on Linux, I think it’s time to revisit some of my original advice on using this combination.

Unfortunately the presentations and MySQL University sessions back then have all been taken down. But that doesn’t mean the advice is any less valid.

Some of the core advice for using InnoDB on ZFS:

  • Configure a single InnoDB tablespace, rather than configuring multiple tablespaces …

Percona Live 2013, MySQL, Continuent and an ever-healthy Ecosystem

I’m sitting here in the lounge at SFO thinking back on the last week, the majority of which has been spent meeting my new workmates and attending the Percona MySQL conference.

For me it has been as much of a family reunion as it has been about seeing the wonderful things going on in MySQL.

Having joined Continuent last month after an ‘absence’ in NoSQL land of almost 2.5 years, joining the MySQL community again just felt like coming home after a long absence. And that’s no bad thing. On a very personal level it was great to see so many of my old friends, many of whom were not only pleased to see me, but pleased to see me working back in the MySQL fold. Evidently many people think this is where I belong.

What was great to see is that the MySQL community is alive and well. Percona may be the drivers behind the annual MySQL conference that we have come to know, but …
