.SysMachineMsgq: message queue blocking

Hi,
I am getting the following error message:
064222.hostname!TMSYSEVT.14351.3071440608.0: WARN: .SysMachineMsgq: hostname message queue blocking
Is there anyway to pinpoint exactly which application and or which service is causing the blocking?
Thank you,
Ivan

Ivan,
You can look in the userlog for a "LIBTUX_CAT:672 ERROR: Message operation
failed because the message queue or the system is full" message. That will
tell you the process in which the msgsnd() failed, although it will not tell
you the specific queue that was full. If the queue full condition is not
something transient, you can use the "ipcs -q -a" command to examine the
number of bytes currently on each queue on the machine.
If you need to automate the process of searching the ULOG, the T_ULOG class
in TM_MIB(5) can be used.
The event message for the SysMachineMsgq event deliberatly contains very few
details, since the process where msgsnd() failed uses a message to inform
the event server of the failure and if a message queue is full, then there
might be a problem with sending a large message to the TMSYSEVT server.
(There is a check to prevent looping if the message send to TMSYSEVT fails.)

Message Queue Blocking / MSGMNI Setting

Hi All,
Firstly, many thanks to all that can assists. I am currently getting Message Queue
Blocking messages in my ULOG files in my Tuxedo Application. (Tux ver 7.1 in Unix).
I am not sure what is causing this, but started to look into the Tux Config (UBB.MP)
and System message queue setting. Detailed as follows:
1)
Listed below is the system message queue setting:
set msgsys:msginfo_msgmni=2000
set msgsys:msginfo_msgmax=128000
set msgsys:msginfo_msgmnb=100000
set msgsys:msginfo_msgssz=256
set msgsys:msginfo_msgseg=25088
set msgsys:msginfo_msgtql=1550
set msgsys:msginfo_msgmap=1000
According to the BEA site, the MSGMNI is determined by this formula:
MSGMNI = MAXACCESSERS + 7 + (no. of servers with REPLYQ) + (no. MSSQ sets) - (no.
of servers with MSSQ sets)
The following is my current Tux. Config (UBB.MP) is set as :
- MAXACCESSERS = 2300
- Each servers (4 types in total) has its own REPLYQ and RQADDR.
- The same type of servers are set the same across 4 application servers.
Hence, my MSGMNI should be a minimum 2339 (ie. MSGMNI = 2300 + 16 + 16 - 0 = 2339).
But my current MSGMNI is 2000.
Would this contribute to my Message Queue Blocking?
Is my understanding correct and is this something I should change to avoid Message
Queue Blocking? Any helps and advice is much appreciated.

Malcolm,
Your information and explanations behind these error messages are very useful.
It allow me to further understand Tuxedo internal processing and at the same time
give me a chance to start analysing these fields.
I am reluctant to ask further questions at the mean time. I will use your suggestions
as a starting point.
I will certainly keep you posted of the outcome when I have made the changes in
my UBB config and machine parameters.
Many thanks with your help/explanations Malcolm. It helps alot!
Cheers.
David.

Hi David,
The MSGTQL reference you give (Solution S-00488) refers to the BEA MessageQ
product
and is not relevant to Tuxedo.
The error messages indicate that the queue buildup is probably due to
a restartable
server failing. What happens is this:
When a restartable server fails its IPC queue remains in place and continues
to
receive messages (which will be processed when the server restarts).
Depending
on the time taken to restart, the queue could become full and unable
to receive
any more messages, and this is probably why you got the message CMDTUX_CAT:1380
indicating that the BRIDGE process was unable to put a message on the
server's
queue.
A server is only restarted when the BBL does a SANITYSCAN check. If,
for example,
your SANITYSCAN interval is 300 seconds and your server fails immediately
after
the previous scan, then there will be a delay of almost 5 minutes before
the failure
is detected and the server restarted - plenty of time for the queue to
fill up.
There are a few things you could do:
The key thing would be to find out why the server is failing, and fix
the problem.
If this is not possible immediately, consider some of the other ideas
below.
Have several servers form an MSSQ to service this queue; then if one
fails the
others will continue processing the messages while the failed server
restarts
(this assumes, of course, that your application does not require the
messages
to be processed in strict order through the server).
Reduce the SANITYSCAN interval (but don't make it too small). This would
reduce
the average time taken to restart the server.
Increase the size of the IPC queue (MSGMNB) so that it can hold more
messages.
I'm not sure why you got a LIBTUX_CAT:1485 message, but this could be
due to a
BRIDGE failure as a result of the congestion.
The NETLOAD parameter would reduce the number of messages going to the
remote
machine, but only if the local machine offers the same service. If the
remote
machine is the only source of the service then NETLOAD will have no effect.
I
recommend you do a search of this newsgroup for postings on "load balancing"
there's some good stuff which will explain how load balancing works.
Depending how things go, it might not be a bad idea to open a case with
BEA Support
and ask for guidance (remember to submit your ubbconfig (or preferably
do a tmunloadcf)
together with the complete ULOGs from both the master and the slave machine).
Hope this helps some.
Regards,
Malcolm.

Hi Malcolm,
Thank you for your reply. Interesting point you have made about theMSGTQL
value.
Based on your suggestion I went hunting around the BEA site and found
the following
snipplet:
"- The MSGTQL parameter must be set to a value greater than or
equal to the MSGMNI setting."
(http://support.bea.com/application?namespace=askbea&origin=ask_bea_answer.jsp&event=link.view_answer_page_solution&answerpage=solution&page=msq/S-00488.htm)
If the above point is valid, then my MSGTQL is definitely way too low.
IF this
be the case, would you know of a method to work out what my MSGTQL bytes
value
should be?
Additionally, I have looked at other parameters which I could tune,and
would
adding a NETLOAD parameter in the *MACHINES section will reduce remote
servers
call? Which potentially, maybe reduce message queue blocking?
FYI:
The error messages I am seeing in my ULOG file are:
"LIBTUX_CAT: 1477 : ERROR .SysServerDied
LIBTUX_CAT: 1476 : ERROR: .SysServerRestarting"
Which then leads to message queue blocking
"CMDTUX_CAT: 1380 : ERROR: Message queue blocking prevented delivery,
Qaddr=..."
and potentially "LIBTUX_CAT: 1485 .SysNetworkDropped."
Many Thanks. Hope to hear from you (Malcolm) or other parties out there
that can
assists.
Thanks.

CMDTUX_CAT:1380: ERROR: Message queue blocking prevented delivery

Today, I changed a Tuxedo application (server) to the product systems(One master and two slaves). Only a small changes in code. But after a period of running, there are many errors in ULOG:
CMDTUX_CAT:1380: ERROR: Message queue blocking prevented delivery, Qaddr = 583902
And then, the server is died. After restart the server, this will happen again later.
I don't know why this happens? Thx.

Hi Bill,
This is happening because the BRIDGE process received a message from the network and was unable to place the message on the intended IPC queue. This could be because the server handling that message is backed up, or the system IPC resource settings are too low. Please check the recommended actions in:

Delete message queues

I had iconnection problems between one of the POA and MTA and I restored this connection after a couple days.
now I can see the poa open on the MTA bus the message between the post-offices are not working.
I thinking the delete the message queue because I believe that there is possible problem with the queue ( any bad message that blocked it).
How can I clean the POA queue ?
Tks.

* ffernandesv,
down the MTA, under the MTA directory, rename the MSLOCAL\MSHOLD\<postoffice>\ folder of the troubling PO. The folder will get recreated when you restart the MTA.
Also down the POA and rename the WPCSIn and WPCSOUT directory under the POA's directory structure.

Queue Blocking and File picked Partially Problem ?

Hi All,
The File which is placed in FTP server having more 50000 to 65000 rows .
when XI picks the File the Partial Data is processed.
In SXMB_MONI if we check the message we are able to see some rows not full Data which was in file.
it's also blocking the Large message QUEUE -XBTM0000
while processing.
In QUEUE monitoring(SMQ2) the STATUS message is "Connnection CLosed No DATA" .
what could the reason here and also we are not able see any error related information(If it is having error) in SXMB_MONI.
it's urgent because of Production issue.

Problem with GlassFish and Sun Java System Message Queue

Hi,
I used application server PE.8 and I upgraded to Sun Java System Application Server Platform Edition 9.0 Update 1 Patch 1, and I changed all my CLASSPATH and everything. My system is working fine, but the Sun Java System Message Queue that I used before is still showing the queues and physical queues of the previous application server, not the new one. Do you know if there is way to change that and link it to the new version?
thanks

Use an ESB like ServiceMix to bridge JMS providers
http://servicemix.org/
Or write your own MessageListener to consume from one JMS and publish on another one. Be careful with queues to avoid loosing the ordering - so you probably want to use a single MessageListener per subscription/queue - or to take advantage of Tibco's exclusive queues to ensure ordering is preserved. If ordering doesn't matter then don't worry too much about it and maybe have a pool of consumers to improve throughput

Error message without blocking Input fields

Hi,
I want to display an error message in the selection screen. The error is for input date validation. But the once error displays in the status bar, it blocks the input fields in the selection screen. I want to display the error message without blocking any of the input parameter in the selection screen. Where should i write the code?
Thanks in advance.

Hi Ezhilhrh
I think you could have done a trial with different message types before posting this question.
Please try with success message(Type - S) and DISPLAY LIKE 'E'.
And also control the program flow using a flag or by checking the initiality of your internal table.

Oracle tuxedo and Oracle tuxedo message queue on top of a virtual machine.

Hi buddies.
how is it going?
A quick question.
So we are going to go live using Oracle Tuxedo 12.1.1.0 with Distinguished Bulletin Board Liaison and Oracle Tuxedo Message Queue 12.1.1.0 on top of a Virtual Machine (VMWARE) running Oracle Linux 6.2. However we want to know if there are any recommendations or mishaps in which we may face ahead by running Oracle Tuxedo on a virtual machine?
I mean, I am wondering if I have to worry about kernel parameters, virtual machine parameters or any other thing from which could mess up everything.
Another question.
Does oracle also provide virtual machines certification where Oracle tuxedo would run on top of ?
Todd Little-Oracle
Maurice G

Hi Bruno,
I'm not sure what you mean with Distinguished Bulletin Board Liaison. I'm guessing you mean a clustered or MP configuration? And is it truly a clustered configuration or just a single machine MP configuration?
Regarding configuration, are you using Tuxedo services as well or just Tuxedo Message Queue? The biggest issue related to OS configuration is around IPC resources. If you do a tmloadcf -c on your UBBCONFIG file, it will help you determine the minimum IPC resources required. In general I suggest configuring significantly more resources than the minimum to allow for future changes and for some of the parameters for heavier loads. In particular IPC message queue parameters are heavily dependent upon load. So make sure the maximum message size and queue size are large enough for your anticipated workload. You can monitor them under load using the ipcs command.
We don't certify virtual machine environment but support them as long as the VM vendor assures compatibility, which obviously VMware and Oracle VM both do.

When I try to play youtube video I get the message of blocked plug-in, and I can not play video using Safari. (Youtube works fine with google chrome) I tried installing flash player HTML5 etc... but still no difference.

I just installed OSX Mountian Lion, and ever since then I can not play youtube video's. I get the message of 'Blocked Plug-in' in the youtube screen. I have tried installing Adobe Flash Player. HTML 5, also tried enabling/disabling java, but nothing worked out. Is there any way I can play youtbe vieos on Safar. (It works fine with Google Chrmoe, only safari has problem)

If you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. Safari > Preferences > Extensions
It can also be installed as a plugin in /Library/Internet-Plug-Ins.
Try uninstalling the currently installled Flash plugin (required for most YouTube content) then reinstall new > Troubleshoot Flash Player | Mac OS
From your Safari menu bar top of your screen click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Now from the menu bar click Develop > Empty Caches

App Server Install fails - due to incompatible Message Queue

I had JES 2005 q1 installed in one of the test machines...now I am trying to set up JES 2005q4 on that. I cud install a Web Server on that ut when I tried to set up the App Server it throws up a msg stating that there is an incompatible version of Message Queue installed and hence installation cannot go ahead.
I am not able to find any instance of Message Queu setup....how do I detect and uninstall old versions of Message Queue??
thx
anand

I assume you are talking about appserver install on Solaris. Message Queue on Solaris is a package based install. The easiest way to uninstall the old version of MQ is: "pkginfo -i | grep Message" ---> "pkgrm all MQ packages".

Clearing JAVA Message Queue in PI 7.1

Hi Experts
I am working on a file to File Scenario, and file has been picked up on the sender CC and mesaages have been sent to JAVA queues, But the messages are stuck on the JAVA queues,
Java Queue name: File_http://sap.com/xi/XI/SystemRecv
How can I clear the JAVA message queue in PI 7.1
Thanks
PR

If the messages are on the queue, usually one of the actions must be performed: a) Fix the related scenario and restart the messages or b) Manually cancel the messages. This is also advised on the note below under item "3. Troubleshooting Archiving / Deletion in the Adapter Framework"
[Note 872388 - Troubleshooting Archiving and Deletion in PI|https://service.sap.com/sap/support/notes/872388]
If you are having performance problems, please check if the messages are taking long time in TBDL/Holding status. Let us know if this is the case.

Hi, try [setSequenceId|http://help.sap.com/javadocs/pi/pi711sp03/com/sap/engine/interfaces/messaging/api/Message.html#setSequenceId(java.lang.String)]. Maybe you have to use setDeliverySemantics before in order to set EOIO.
