How to move a website and domain name without experiencing downtime for emails or site?

- by user4842

Okay, I have a pretty complex problem, so I'll get right to it. I'm a designer who built a new website for my client. Their old site is hosted at GoDaddy, as well as their email. Problem is, the guy who built the original site decided to put the original domain name and hosting under HIS personal GoDaddy account. Well, that turned out to be a bad move for several reasons. Here's how it's all tied together. The original domain name, www.domainoriginal.com, was actually purchased at Network Solutions. The original web designer pointed the nameservers from Network Solutions to his GoDaddy account, where the email and hosting is setup. The new domain name, www.domainnew.com, was purchased under a new and separate GoDaddy account belonging to the company, and the new website was built under a 3rd party platform (Big Commerce). So, the www.domainnew.com is already pointed to the new website using A records at new GoDaddy account. All is fine there. However, they still need www.domainoriginal.com to point to the NEW website as well. (The old one can simply be deleted, it is NOT important). AND, they want to keep their old email addresses intact and working as well, but under the NEW GoDaddy account. Obviously, I have no DNS control at Network Solutions, and I have no idea what kind of control I have at GoDaddy under the old account because the web designer will not let me see inside his account. But, he and GoDaddy both tell me nothing can be done other than to repoint the nameservers to Network Solutions, and then repoint the A record to my new website, www.domainnew.com, and point the MX Records to GoDaddy. I'm told the downtime would be 24-48 hours if I do this. Ideally, we'd like to do a domain name transfer and get www.domainoriginal.com in the new GoDaddy account created by the company. But, I'm told this could take up to 7 days. Does this mean the site and email will be down for 7 days? And any emails sent during this time, would they be lost forever? If I do this, how long could I expect the site and email to go down? And, will the emails be permanently lost? I've gotten different answers from everybody at GoDaddy so I kind of don't trust them anymore... Any help would be greatly appreciated Thanks, Tyson

ZFS for Database Log Files

- by user12620111

I've been troubled by drop outs in CPU usage in my application server, characterized by the CPUs suddenly going from close to 90% CPU busy to almost completely CPU idle for a few seconds. Here is an example of a drop out as shown by a snippet of vmstat data taken while the application server is under a heavy workload. # vmstat 1 kthr memory page disk faults cpu r b w swap free re mf pi po fr de sr s3 s4 s5 s6 in sy cs us sy id 1 0 0 130160176 116381952 0 16 0 0 0 0 0 0 0 0 0 207377 117715 203884 70 21 9 12 0 0 130160160 116381936 0 25 0 0 0 0 0 0 0 0 0 200413 117162 197250 70 20 9 11 0 0 130160176 116381920 0 16 0 0 0 0 0 0 1 0 0 203150 119365 200249 72 21 7 8 0 0 130160176 116377808 0 19 0 0 0 0 0 0 0 0 0 169826 96144 165194 56 17 27 0 0 0 130160176 116377800 0 16 0 0 0 0 0 0 0 0 1 10245 9376 9164 2 1 97 0 0 0 130160176 116377792 0 16 0 0 0 0 0 0 0 0 2 15742 12401 14784 4 1 95 0 0 0 130160176 116377776 2 16 0 0 0 0 0 0 1 0 0 19972 17703 19612 6 2 92 14 0 0 130160176 116377696 0 16 0 0 0 0 0 0 0 0 0 202794 116793 199807 71 21 8 9 0 0 130160160 116373584 0 30 0 0 0 0 0 0 18 0 0 203123 117857 198825 69 20 11 This behavior occurred consistently while the application server was processing synthetic transactions: HTTP requests from JMeter running on an external machine. I explored many theories trying to explain the drop outs, including: Unexpected JMeter behavior Network contention Java Garbage Collection Application Server thread pool problems Connection pool problems Database transaction processing Database I/O contention Graphing the CPU %idle led to a breakthrough: Several of the drop outs were 30 seconds apart. With that insight, I went digging through the data again and looking for other outliers that were 30 seconds apart. In the database server statistics, I found spikes in the iostat "asvc_t" (average response time of disk transactions, in milliseconds) for the disk drive that was being used for the database log files. Here is an example: extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 2053.6 0.0 8234.3 0.0 0.2 0.0 0.1 0 24 c3t60080E5...F4F6d0s0 0.0 2162.2 0.0 8652.8 0.0 0.3 0.0 0.1 0 28 c3t60080E5...F4F6d0s0 0.0 1102.5 0.0 10012.8 0.0 4.5 0.0 4.1 0 69 c3t60080E5...F4F6d0s0 0.0 74.0 0.0 7920.6 0.0 10.0 0.0 135.1 0 100 c3t60080E5...F4F6d0s0 0.0 568.7 0.0 6674.0 0.0 6.4 0.0 11.2 0 90 c3t60080E5...F4F6d0s0 0.0 1358.0 0.0 5456.0 0.0 0.6 0.0 0.4 0 55 c3t60080E5...F4F6d0s0 0.0 1314.3 0.0 5285.2 0.0 0.7 0.0 0.5 0 70 c3t60080E5...F4F6d0s0 Here is a little more information about my database configuration: The database and application server were running on two different SPARC servers. Storage for the database was on a storage array connected via 8 gigabit Fibre Channel Data storage and log file were on different physical disk drives Reliable low latency I/O is provided by battery backed NVRAM Highly available: Two Fibre Channel links accessed via MPxIO Two Mirrored cache controllers The log file physical disks were mirrored in the storage device Database log files on a ZFS Filesystem with cutting-edge technologies, such as copy-on-write and end-to-end checksumming Why would I be getting service time spikes in my high-end storage? First, I wanted to verify that the database log disk service time spikes aligned with the application server CPU drop outs, and they did: At first, I guessed that the disk service time spikes might be related to flushing the write through cache on the storage device, but I was unable to validate that theory. After searching the WWW for a while, I decided to try using a separate log device: # zpool add ZFS-db-41 log c3t60080E500017D55C000015C150A9F8A7d0 The ZFS log device is configured in a similar manner as described above: two physical disks mirrored in the storage array. This change to the database storage configuration eliminated the application server CPU drop outs: Here is the zpool configuration: # zpool status ZFS-db-41 pool: ZFS-db-41 state: ONLINE scan: none requested config: NAME STATE ZFS-db-41 ONLINE c3t60080E5...F4F6d0 ONLINE logs c3t60080E5...F8A7d0 ONLINE Now, the I/O spikes look like this: extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1053.5 0.0 4234.1 0.0 0.8 0.0 0.7 0 75 c3t60080E5...F8A7d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1131.8 0.0 4555.3 0.0 0.8 0.0 0.7 0 76 c3t60080E5...F8A7d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1167.6 0.0 4682.2 0.0 0.7 0.0 0.6 0 74 c3t60080E5...F8A7d0s0 0.0 162.2 0.0 19153.9 0.0 0.7 0.0 4.2 0 12 c3t60080E5...F4F6d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1247.2 0.0 4992.6 0.0 0.7 0.0 0.6 0 71 c3t60080E5...F8A7d0s0 0.0 41.0 0.0 70.0 0.0 0.1 0.0 1.6 0 2 c3t60080E5...F4F6d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1241.3 0.0 4989.3 0.0 0.8 0.0 0.6 0 75 c3t60080E5...F8A7d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1193.2 0.0 4772.9 0.0 0.7 0.0 0.6 0 71 c3t60080E5...F8A7d0s0 We can see the steady flow of 4k writes to the ZIL device from O_SYNC database log file writes. The spikes are from flushing the transaction group. Like almost all problems that I run into, once I thoroughly understand the problem, I find that other people have documented similar experiences. Thanks to all of you who have documented alternative approaches. Saved for another day: now that the problem is obvious, I should try "zfs:zfs_immediate_write_sz" as recommended in the ZFS Evil Tuning Guide.

4.8M wasn't enough so we went for 5.055M tpmc with Unbreakable Enterprise Kernel r2 :-)

- by wcoekaer

We released a new set of benchmarks today. One is an updated tpc-c from a few months ago where we had just over 4.8M tpmc at $0.98 and we just updated it to go to 5.05M and $0.89. The other one is related to Java Middleware performance. You can find the press release here. Now, I don't want to talk about the actual relevance of the benchmark numbers, as I am not in the benchmark team. I want to talk about why these numbers and these efforts, unrelated to what they mean to your workload, matter to customers. The actual benchmark effort is a very big, long, expensive undertaking where many groups work together as a big virtual team. Having the virtual team be within a single company of course helps tremendously... We already start with a very big server setup with tons of storage, many disks, lots of ram, lots of cpu's, cores, threads, large database setups. Getting the whole setup going to start tuning, by itself, is no easy task, but then the real fun starts with tuning the system for optimal performance -and- stability. A benchmark is not just revving an engine at high rpm, it's actually hitting the circuit. The tests require long runs, require surviving availability tests, such as surviving crashes -and- recovery under load. In the TPC-C example, the x4800 system had 4TB ram, 160 threads (8 sockets, hyperthreaded, 10 cores/socket), tons of storage attached, tons of luns visible to the OS. flash storage, non flash storage... many things at high scale that all have to be perfectly synchronized. During this process, we find bugs, we fix bugs, we find performance issues, we fix performance issues, we find interesting potential features to investigate for the future, we start new development projects for future releases and all this goes back into the products. As more and more customers, for Oracle Linux, are running larger and larger, faster and faster, more mission critical, higher available databases..., these things are just absolutely critical. Unrelated to what anyone's specific opinion is about tpc-c or tpc-h or specjenterprise etc, there is a ton of effort that the customer benefits from. All this work makes Oracle Linux and/or Oracle Solaris better platforms. Whether it's faster, more stable, more scalable, more resilient. It helps. Another point that I always like to re-iterate around UEK and UEK2 : we have our kernel source git repository online. Complete changelog of the mainline kernel, and our changes, easy to pull, easy to dissect, easy to know what went in when, why and where. No need to go log into a website and manually click through pages to hopefully discover changes or patches. No need to untar 2 tar balls and run a diff.

Difference between a socket and a port

- by cobie

Could someone please explain quite clearly the difference between a port and a socket. I know that a port serves as a door into the network for an application process and that the application process uses a socket connection to the given port number to handle network communication but when you have multiple processes listening on a single port number, I am finding it difficult to understand the difference between the socket and the port and how they all fit together.

How are Reads Distributed in a Workload

- by Bill Graziano

People have uploaded nearly one millions rows of trace data to TraceTune. That’s enough data to start to look at the results in aggregate. The first thing I want to look at is logical reads. This is the easiest metric to identify and fix. When you upload a trace, I rank each statement based on the total number of logical reads. I also calculate each statement’s percentage of the total logical reads. I do the same thing for CPU, duration and logical writes. When you view a statement you can see all the details like this: This single statement consumed 61.4% of the total logical reads on the system while we were tracing it. I also wanted to see the distribution of reads across statements. That graph looks like this: On average, the highest ranked statement consumed just under 50% of the reads on the system. When I tune a system, I’m usually starting in one of two modes: this “piece” is slow or the whole system is slow. If a given piece (screen, report, query, etc.) is slow you can usually find the specific statements behind it and tune it. You can make that individual piece faster but you may not affect the whole system. When you’re trying to speed up an entire server you need to identity those queries that are using the most disk resources in aggregate. Fixing those will make them faster and it will leave more disk throughput for the rest of the queries. Here are some of the things I’ve learned querying this data: The highest ranked query averages just under 50% of the total reads on the system. The top 3 ranked queries average 73% of the total reads on the system. The top 10 ranked queries average 91% of the total reads on the system. Remember these are averages across all the traces that have been uploaded. And I’m guessing that people mainly upload traces where there are performance problems so your mileage may vary. I also learned that slow queries aren’t the problem. Before I wrote ClearTrace I used to identify queries by filtering on high logical reads using Profiler. That picked out individual queries but those rarely ran often enough to put a large load on the system. If you look at the execution count by rank you’d see that the highest ranked queries also have the highest execution counts. The graph would look very similar to the one above but flatter. These queries don’t look that bad individually but run so often that they hog the disk capacity. The take away from all this is that you really should be tuning the top 10 queries if you want to make your system faster. Tuning individually slow queries will help those specific queries but won’t have much impact on the system as a whole.

Is it possible to add a notification ballon, like the one I see when the network connection is estabilished? P.s if the connection fail or is dropped, the notification cames out like this:

This is mostly a repost of LaoTsao's Weblog with some tweaks. Last time that I tried to cut & paste directly off of his page, some of the XML was messed up. I run this from my MacBook.

How does juju expose work?

- by user84471

If I expose my service, for instance teamspeak server, on what address it will be running? On my server address? For example: my server has an address of 158.37.15.167. If I deploy teamspeak from my local network (10.0.0.0) connected to the server, how will it be seen in the 158.37.15.167 network? When I run juju status I get this: public-address: nodeTWO.localdomain instead of an IP address. My juju status: http://pastebin.com/z99Bhx9G

rt2800 wireless keeps disconnecting

- by Matthew Fumi

My HP dm1 laptop has a rt2800sta wlan driver. My wireless doesn't usually have a problem connecting to a network, yet sometimes it does. The biggest issue I have found is that when it does connect, it doesn't stay connected. It continually connects and disconnects to the network. Does anyone know why this is happening, and how I would go about fixing the issue? Thank you and look forward to trying your solutions.
