Hacking SLOB to run on Solaris

Kevin Closson’s Silly Little Oracle Benchmark https://kevinclosson.net/slob/ is not ported to Solaris. This means that to get it working is not as easy as it should be. Kevin himself suggests that you use a small linux host to run the tool if your database is running on a non-supported operating system.

I’m going to track the changes I make here.

setup.sh

First problem – grep!

./setup.sh test 16
SLOB 2.4.0
FATAL : 2018.05.15-14:40:57 : Usage : ./setup.sh.orig: <tablespace name> <number of SLOB schemas to create and load>
FATAL : 2018.05.15-14:40:57 : Option 2 must be an integer

This is caused by the function f_is_int requiring the gnu grep command behaviour. Simplest way to this is to change the grep to point to /usr/gnu/bin/grep in this script.

Next problem..

Once this change was made, I was then able to create the first schema ( yay!) but then when it came to make the remaining 15, it failed.

Handily there is an error message in the logfile

I’m going to assume the clue is in the error and increase the PGA aggregate limit

After this change, the script ran to the end successfully.

runit.sh

So – we already know that the scripts need gnu grep, especially in the function f_is_int. Safest option will be  to change every occurrence of grep with /usr/gnu/bin/grep.

Try running it with a single schema

 ./runit.sh 1

The duration of the run is based on the slob.conf variable RUN_TIME. The default is 300 seconds, but I am dropping it to 90 while I am doing debugging.

This ran successfully (I think!). Certainly AWR reports were created.

There was one obvious failure – the mpstat output was not generated.

$ cat mpstat.out 
mpstat: -P expects a number
Usage: mpstat [-aqm] [-A core|soc|bin] [-k key1,[key2,...]] [-o num] [-p | -P processor_set] [-T d|u] [-I statfile | -O statfile ] [interval [count]]

Ok – so this is the line causing the problem.

 ( mpstat -P ALL 3 > mpstat.out 2>&1) &

On Linux mpstat without the -P flag will give you summary output, -P separates the output by processor.  On Solaris the default is to show one line per CPU, so I just need to change the line to

 ( mpstat 3 > mpstat.out 2>&1) &

also check for other invocations of mpstat

Next - try with 2 sessions

./runit.sh 2

Arrgh. That fails with

: List of monitored sqlplus PIDs written to /tmp/.SLOB.2018.05.15.153524/13174.f_wait_pids.out.
usage: ps [ -aAdefHlcjLPyZ ] [ -o format ] [ -t termlist ]
 [ -u userlist ] [ -U userlist ] [ -G grouplist ]
 [ -p proclist ] [ -g pgrplist ] [ -s sidlist ] [ -z zonelist ] [-h lgrplist]
 'format' is one or more of:
 user ruser group rgroup uid ruid gid rgid pid ppid pgid sid taskid ctid
 pri opri pcpu pmem vsz rss rssprivate rssshared osz nice class time etime stime zone zoneid env
 f s c lwp nlwp psr tty addr wchan fname comm args projid project pset lgrp

This wasn’t obvious where the fault was happening. So lets add the -x flag to the first line of our script to try and find the line causing our problems.

++ sed /PID/d
++ wc -l
+++ cat /tmp/.SLOB.2018.05.15.153852/15451.f_wait_pids.out
++ sed 's/[^0-9]//g'
++ ps -p 32526 32527
usage: ps [ -aAdefHlcjLPyZ ] [ -o format ] [ -t termlist ]
 [ -u userlist ] [ -U userlist ] [ -G grouplist ]
 [ -p proclist ] [ -g pgrplist ] [ -s sidlist ] [ -z zonelist ] [-h lgrplist]
 'format' is one or more of:
 user ruser group rgroup uid ruid gid rgid pid ppid pgid sid taskid ctid
 pri opri pcpu pmem vsz rss rssprivate rssshared osz nice class time etime stime zone zoneid env
 f s c lwp nlwp psr tty addr wchan fname comm args projid project pset lgrp
++ return 0
+ tmp=0

So there is something with the ps -p command that is not happy in solaris. I  can reproduce the problem at my command line, by providing ps -p with multiple pids.


# ps -p 7 8
usage: ps [ -aAdefHlcjLPyZ ] [ -o format ] [ -t termlist ].....

If we look at the ps man page, on solaris it says

Some options accept lists as arguments. Items in a list can be either
separated by commas or else enclosed in quotes and separated by commas
or spaces. Values for proclist and grplist must be numeric.

so this means the following will work, but not the format within runit.sh

# ps -p 7,8
 PID TTY TIME CMD
 7 ? 127:47 zpool-rp
 8 ? 1:39 kmem_tas
# ps -p "7 8"
 PID TTY TIME CMD
 7 ? 127:47 zpool-rp
 8 ? 1:39 kmem_tas

 

So – I need to find the line with ps command, and try to change the format presented.

while ( ps -p $pidstring > /dev/null 2>&1 )

 ps -fp $pidstring

both occur in function f_wait_pids

but, they are actually being presented with the list of pids built up in line 1440

sqlplus_pids="${sqlplus_pids} $!"

So – how do I go about getting either a comma or a quote in the string that is passed to the function f_wait_pids?

Well, rather than destroying something that Kevin may rely on later, I add a line below 1440 to generate the pid list with commas

 melsqlplus_pids="${melsqlplus_pids},$!"

This is pretty ugly, as it means my string leads with a comma. However it seems that Solaris doesn’t care about this.

Now I need to add this to the function call on line 1493

if ( ! f_wait_pids "$(( SCHEMAS * THREADS_PER_SCHEMA ))" "$RUN_TIME" "$WORK_LOOP" "$sqlplus_pids"  "$melsqlplus_pids")

Of course I need to add something to pick up that new 5th argument to the function, so within the function itself

local melpidstring="$5"

while ( ps -p "$melpidstring" > /dev/null 2>&1 )

ps -fp "$melpidstring"

So this all seems ok.. but then I discover some more little rats in f_count_pid.

So once again – create my own custom usage of the pid list. There probably is a MUCH simpler way to do this, I’m just building it up as I go along. So – here are the changes I have made to runit.sh to get it to execute without error

Tomorrow – time to get someone else to run it and see if it behaves how they expect.

Dimstat and add on stats

In my working life I regularly use a tool called Dimstat, a unix performance monitoring tool which stores the statistics into a MySQL database. The tool is written by a former colleague and is available from http://dimitrik.free.fr/

It comes with ‘built in’ support to gather standard unix statistics such as vmstat, mpstat but one of the great features is the ability to add new statistics collection methods. It can handle single line output (e.g. vmstat) or multi line output like mpstat. Let’s say we want to gather filesystem utilisation information based on the output of df -k. This will be a multi-line STAT as we will have more than one filesystem reported.

Creating your script

First you create your script that gathers the information you want. You must remember to include a line separator field in your output (default newline) so dimstat knows that the record is complete and also a field to accept the interval.

So here’s my basic script, you may want to adjust the filesystems I am excluding from the list (or make the egrep more elegant!)

# cat mel_df.sh
#!/bin/bash
while true
do
df -k |egrep -v 'fd|mnttab|objfs|sharetab|Filesystem|volatile|proc|devices|contract|dev' | sort | awk  '{ print $6 " " $2 " " $3 " " $4}'
echo ""
sleep $1
done

Test your script interactively

Now you copy the script into /etc/STATsrv/bin on the hosts you want to capture the statistics from.

Then you edit the /etc/STATsrv/access file and add a line pointing to your script, and giving it the name ‘DF_CHECK’

command  DF_check       /etc/STATsrv/bin/mel_df.sh

On the host with the STATsrv demon we can check if this stat is advertised and available..

Declaring your script to the Dimstat server

You have 2 methods to declare your script to the server, either via the GUI or by importing a stat definition file (the format for these files make this option for experienced users only)

Via the GUI you select ADD-on STATS -> Integrate new ADD-on STAT

Enter the name of your STAT: DF_check and complete the information about the column names and data types

dimstat

Once you have declared your add on stat you should now be able to start a new collect on the host using your new statistic. Once it has collected some data, the button for your statistic will become visible in the Analyze page.

mp3splt

mp3splt is a really useful little tool to chop big mp3s into smaller ones. I use it mainly to split audio books into finer grained sections for easier navigation in the car or on my ipod.

To achieve this I use the following command

C:\Program Files (x86)\mp3splt>mp3splt d:\temp\audio\TheAdventureoftheBlueCarbun
cle.mp3 -a -t 30.00 -d d:\temp\audio\bluecarbuncle

This will split my mp3 file into 30 minute (-t 30.00) chunks, auto adjusting to cut in silent parts (-a) and writing the output files into a directory, creating if necessary.

CURL – curl: (9) Server denied you to change to the given directory

I hit this error trying to import some VMs into OVM

To get more detail I tried the command from the ocmmand line

curl -v "ftp://root:blahroot@192.168.8.192/var/tmp/taxud-disk1.vmdk"
* About to connect() to 192.168.8.192 port 21

This is because the pathname I have given is relative, rather than absolute, so I was unknowingly trying to change directory to /root/var/tmp which did not exist.

To give an absolute pathname, you need an extra slash

curl “ftp://root:blahroot@192.168.8.192//var/tmp/taxud-disk1.vmdk”

Strange behaviour of listener_networks and scan listener

I had an Exalogic and a Sparc SuperCluster T4-4 connected together by infiniband for a set of tests. This meant that I was able to enable SDP and IP over the infiniband network.

To configure it, I had followed the instructions in the Exalogic Manual.

After setting the listener_networks parameter I checked whether the services had registered correctly with the scan listener. Expected behaviour is to see all instances registered with all 3 scan listeners

– Set your environment to the GRID_HOME

- Check which nodes are running the scan listener as you can only interrogate the listener from that node

 oracle@ssca01:~$ srvctl status scan
 SCAN VIP scan1 is enabled
 SCAN VIP scan1 is running on node ssca03
 SCAN VIP scan2 is enabled
 SCAN VIP scan2 is running on node ssca04
 SCAN VIP scan3 is enabled
 SCAN VIP scan3 is running on node ssca01

So on ssca01, I can check the status of LISTENER_SCAN1 ..
And it had  no services registered. Strange. Checked all of my listeners and only LISTENER_SCAN3 had any services registered

I looked on Oracle Support and I could find no other reports of this problem, but then only a small proportion of customers will be running in this configuration.

However, I did find a note 1448717.1 that documented a similar problem with the remote_listener parameter.

So, I amended my tnsnames.ora file so that my LISTENER_IPREMOTE alias included the 3 scan ip addresses

#LISTENER_IPREMOTE =
#  (DESCRIPTION =
#    (ADDRESS = (PROTOCOL = TCP)(HOST = ssca-scan.blah.com)(PORT = 1521))
#  )

LISTENER_IPREMOTE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 137.3.16.87)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 137.3.16.88)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 137.3.16.89)(PORT = 1521))
  )

You can trace the PMON registration process by setting the following database event

alter system set events=’immediate trace name listener_registration level 3′;

and then issue a alter system register; to force pmon to re-register to listeners.

This will produce a trace file in background_dump dest

Looking through this logfile I saw it was still trying to register with the SCAN address.

 Remote listeners:
  0 - (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=ssca-scan.osc.uk.oracle.com)(PORT=1521)))
       state=1, err=0
       nse[0]=0, nse[1]=0, nte[0]=0, nte[1]=0, nte[2]=0
       ncre=0
       endp=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=ssca-scan.osc.uk.oracle.com)(PORT=1521)))
         flg=0x0 nse=12545

At this point I realised that the tnsnames.ora must only be checked at certain times, such as database startup. So, I restarted my database.

Success! On checkng all of my scan listeners they all had services registered.

Zoning a Brocade Switch Using WWNs

Way back in the mists of time I used to use port based zoning on Brocade switches, however, I started having problems with this and newer storage systems (almost certainly pilot error!). I needed to zone some switches for a customer’s piece of work and this time I thought I’d get with the future and use WWN based zoning.

So, in my setup I have 2 hosts, each with 2 connections per switch, and 2 storage arrays with 1 connection to the switch.

swd77:admin> switchshow

Create aliases for your hosts and storage arrays

swd77:admin> alicreate host1_a,"21:00:00:24:ff:20:3b:92"
swd77:admin> alicreate host1_b,"21:00:00:24:ff:25:6d:ac"
swd77:admin> alicreate host2_a,"21:00:00:24:ff:20:3a:f6"
swd77:admin> alicreate host2_b,"21:00:00:24:ff:20:3a:e0"
swd77:admin> alicreate "a6140","20:14:00:a0:b8:29:f5:56"
swd77:admin> alicreate "b6140","20:16:00:a0:b8:29:cd:b4"

Create Zones to include your alias

swd77:admin> zonecreate "port2","host1_a; a6140; b6140"
swd77:admin> zonecreate "port3","host1_b; a6140; b6140"
swd77:admin> zonecreate "port8","host2_a;  a6140; b6140"
swd77:admin> zonecreate "port9","host2_b;  a6140; b6140"

Create a configuration for your zones and save it

swd77:admin> cfgcreate "customer1","port2; port3; port8; port9"
swd77:admin> cfgsave

Android Calendar Synchronization

My work phone has just been upgraded to a HTC Legend. The phone is very attractive, the screen clear and bright and the choice of applications dizzying.

I did discover one thing that Android did less well than the Nokia E71 – Calendar Synchronization. The native app seems to be totally geared around you being able to use google calendar, which is fine for personal use, but no good if your company uses another calendar technology and prevent you from storing your corporate diary in external services.

The answer I’ve found is the application http://www.hypermatix.com/products/calendar_sync_for_android?q=faq which is able to connect to my corporate calendar and use it to populate the local calendar on my phone. Currently only in Beta, but it seems to be an effective solution to the problem.

Nokia – Free Navigation for all?

There has been a lot of buzz about Nokia making their navigation free forever.

However, it isn’t that simple, unless you are on the short list of phones that support Ovi Maps 3.0.3, you don’t get the free navigation at all. This means if you have a smartphone such as the E71 you don’t get the free navigation, and there are some rumours that you cannot buy new navigation licenses.

Next time, no nokia for me.
