HADR Tools: HADR Calculator

The HADR Calculator is one of three HADR tools provided by IBM on developerWorks. For more details on the other(s), see:
HADR Tools: the HADR Simulator

For the full technical specifications and details on using the HADR tools, see:
https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/DB2HADR/

What are the HADR Tools?

IBM provides three major HADR tools on a devloperWorks wiki site.

The HADR Simulator is used to look both at disk speed and network details around HADR. It can be used in several different ways, including helping you to troubleshoot the way HADR does name resolution.

The DB2 Log Scanner is used to look at log files and report details about your DB2 Workload. The output is a bit cryptic, and this tool is best used in conjunction with the HADR Calculator. This does require real log files from a real workload, so if you’re setting up a new system, you will need to have actual work on the system before you can use it. Also, IBM will not provide the tool they use internally to uncompress automatically compressed log files, so if you want to use it, you’ll have to turn automatic log compression off. I tried to get the tool, they would not give it to me.

The HADR Calculator takes input from the DB2 Log Scanner, and values that you can compute using the HADR Simulator, and tells you which HADR SYNCMODEs make the most sense for you.

These three tools do NOT require that you have DB2 on a server to run – they are fully standalone. There are versions of the first two for each operating system. The third requires that you have perl, but can be run anywhere, including on a laptop or personal computer. This allows you flexibility in considering details of a network or server you are thinking of using before actually using it. And allows you to analyze log files without adding workload to a server.

Using the HADR Calculator

The HADR Calculator requires you to pull four values from the HADR Simulator output and to give it the filename from the db2logscan output.

Getting the Disk Numbers

It’s actually easiest to run the HADR simulator separately to get the disk values using two separate commands:

$ ./simhadr_linux -write test.out -flushSize 1
+ simhadr -write test.out -flushSize 1

Measured sleep overhead: 0.003843 second, using spin time 0.004611 second.
Simulation run time = 4 seconds
use file system cache = false
write behind caching = false

Writing to file test.out
Press Ctrl-C to stop.

Total 136 writes in 4.022017 seconds, 0.029574 sec/write, 1 pages/write

Total 0.557056 MBytes written in 4.022017 seconds. 0.138502 MBytes/sec

Distribution of write time (unit is microsecond):
Total 136 numbers, Sum 4022017, Min 16092, Max 60107, Avg 29573
From 8192 to 16383                 1 numbers
From 16384 to 32767              130 numbers
From 32768 to 65535                5 numbers

AND

$ ./simhadr_linux -write test.out -flushSize 1000
+ simhadr -write test.out -flushSize 1000

Measured sleep overhead: 0.003925 second, using spin time 0.004710 second.
Simulation run time = 4 seconds
use file system cache = false
write behind caching = false

Writing to file test.out
Press Ctrl-C to stop.

Total 46 writes in 4.034771 seconds, 0.087712 sec/write, 1000 pages/write

Total 188.416000 MBytes written in 4.034771 seconds. 46.698065 MBytes/sec

Distribution of write time (unit is microsecond):
Total 46 numbers, Sum 4034771, Min 72366, Max 148424, Avg 87712
From 65536 to 131071              45 numbers
From 131072 to 262143              1 numbers

Now this will actually generate a file on disk, so make sure you have some space where you’re running this, and also delete test.out when done. The numbers to pull out are highlighted above.

Getting the Network Numbers

The network round trip time actually comes from a simple ping:

$ ping server2
PING server2 (000.000.000.000) 56(84) bytes of data.
64 bytes from server2 (000.000.000.000): icmp_seq=1 ttl=64 time=0.124 ms
64 bytes from server2 (000.000.000.000): icmp_seq=2 ttl=64 time=0.152 ms
64 bytes from server2 (000.000.000.000): icmp_seq=3 ttl=64 time=0.083 ms
64 bytes from server2 (000.000.000.000): icmp_seq=4 ttl=64 time=0.076 ms

--- ssadwdevdata ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3001ms
rtt min/avg/max/mdev = 0.076/0.108/0.152/0.033 ms

Note that this value is in ms, and we need it in seconds, so multiply this value by 0.001 to get the value you need to give the HADR calculator.

The final network number needed comes from the HADR Simulator. See my blog entry on the HADR Simulator to see how to run it and the full output. The piece of output we’re looking for is:

Total 18163171328 bytes sent in 60.000131 seconds. 302.718861 MBytes/sec

Executing the HADR Calculator

With all the input pieces gathered, we can run the HADR calculator. The general form of syntax is:

./hadrCalculator.pl –disk <MB/sec> <overhead secs per write> -network <MB/sec> <round trip secs> db2logscan filename

Using the details from the examples in this post, the command would be:

$ ./hadrCalculator.pl -disk 46.698065 0.029574 -network 302.718861 0.000108 db2logscan.bcudb.out
hadrCalculator.pl: Network speed 302.718861 MB/s, 0.000108 second round trip time
hadrCalculator.pl: Disk speed 46.698065 MB/s, 0.029574 second overhead per write

Now the output using my actual values isn’t actually all that useful because in the case of the database I’m analyzing, there would be no predicted slowdowns caused by HADR. So to show you what it looks like, here is the output if I mess with the input values some to the point it would cause problems:

See the question marks (I’ve added the red color) in a few of the lines? That’s really what you’re looking for in this output. A varying number of question marks will be added to lines (portions of log files) where the specified syncmode might cause some performance impact. One question mark is mild impact, two question marks is moderate performance improvement, and three question marks is severe performance impact. If you see three question marks in a real world scenario, consider the fact that you should not use that syncmode, or if there is a requirement for the syncmode that you must somehow change one of the inputs – the disk speed, the network speed, or the transactional activity.

    We turned automatic log compression off.too. If you ever need to do something with a database and archive log files and you have the log files compressed, you are out of luck. We discovered that in a production environment and found it just silly that the vendor wanted us to transmit our log files to them, have them uncompress them and send them back at 2 AM in the morning with no promise as to how many of these we would have to work through manually like this before getting the production environment back online and working. If the vendor wants to hold on to control of when this program is used they can simply use the same approach they use with db2cleancat. Have a new version for each new version of the database and have a 7 day password that you can only get by opening a PMR. Run the program, give it the valid password and uncompress your archive log files so you can use them the way you need to use them in an emergency situation. Otherwise, suffer through a restore of a backup and a partial roll forward if logs backed with that are corrupted too and then suffer through applications playing catch up while your CIO and CEO ask the question, and why do we have you people working for us? Vendors need to get some field experience and then they would understand more about their customers needs.

    Hi everybody…
    i don(t understand what is represented by :
    – flush duration (what is it)
    – What reprersent the ‘numbers’ (Total 348 numbers, Sum 37504, Min 0, Max 7501, Avg 107.770115)
    so i can’t completely read the output of db2logscan
    Thank you for your answer…
