Query regarding Queue block

Hi Experts,
The BASIS team has configured the CCMS alert for XBTI* and XBTO* queues in development system.
Hence we need to test the same.
Possibilities tried:
1. Huge payload
2. Stop and start of BPE this blocks the XBQ which is not needed as of now
3. Deregistering the specific queues. The queus is set to ready state until we register the same. Once registered the queue block is cleared. Hence this option is not helpful.
Kindly let us know the various ways to block the queues in PI.
Thanks
Suganya.

Hi,
If you have any interfaces using EOIO queues then try failing the same at mapping level and check...
Another option is try failing the interface at mapping level by sending some invalid data for normal interfaces (EO) only and check...but in this case runtime may not block the queues all the times only few times and few circumstances it will block the queues...

Query regarding delayed block cleanout

Hi,
I have a question regarding delayed block clean-out in Oracle.
I have read below from meta link note: 40689.1
Consider a transaction that updates a million row table. This obviously visits a large number of database blocks to make the change to the data.
When the user commits the transaction Oracle does NOT go back and revisit these blocks to make the change permanent. It is left for the next
transaction that visits any block affected by the update to 'tidy up' the block (hence the term 'delayed block clean out').
But the rollback segment transaction table slot can be recycled once it is marked as committed.
So if any new transaction tries to visit a block affected by last update and figures out this block is changed and goes to corresponding rollback segment transaction table slot, but that that rollback segment transaction table slot is recycled because of commit.
So how Oracle will handle this situation?
Thanks in advance.

What makes you think that the changed data will be in rollback segment? Rollback segement contains the previous image of data. According to my understanding this should be in the Redo logs.
So if any new transaction tries to visit a block affected by last update and figures out this block is changed and goes to corresponding rollback segment transaction table slot, but that that rollback segment transaction table slot is recycled because of commit.
This should go to the Redo & DBWR process should write all the dirty blocks to disc consequently.

Account fact sheet, print version (PDF). Query regarding output blocks.

I have looked at OSS Note 1066280 which explains exactly how to config the PDF fact sheet. However, on looking at the view or using the SPRO path I can see that there are currenty no settings in place at the moment. i.e. the view/SPRO is showing no data.
However, when looking at the appropriate Smartform I can see blocks for:
Opportunities
Activities
Interaction history
Contact Person
Relationship types
Which all print out (display in PDF) okay, except there's also a Sales block in the Smartform which does not print. The logic/output conditions in the Smartform say PRINT_DATA-SALES_AREAS = 'X' and SALES_AREAS[] NE initial. What controls whether this information prints, config-wise.
Also, I need to add new blocks of data, which is probably going to be sourced from ERP, but config-wise can I control whether the PDF displays these newly created blocks in the same way as it does for the SAP standard?.

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.

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

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:

Return amount of records after query multi-record block

Hello,
I would like to have a restriction in my multi-record form that counts the amount of returning records (after execute_query). If the amount is >= 1000 then I have to raise an error.
How can I implement this?
Best regards,
Ronny.

It most cases forms doesn't return all rows to the user in a batch unless the block property Query-all is set to yes. But if you have sum items based on that block, you have to set it to Yes. If you can turn this flag off and change the Query Array Size (block property) to 0 or something small (like 20), you dont have to worry about how many rows the query is going to return.
In you case, sounds like you want the user to put more constraints if rows returning > 1000 and you probably dont want the user to ever look those rows. You can do a
select count(*) from your_table
where --your critera
and rownum < 1001
before execute the query. But this select might take
a while if you table is very big in oracle 9i.
The easiest thing is to turn off the Query-All switch, let the forms handle the query and let the user decide whether to refine the query.

Query regarding updation thru a Procedure

Hi,I have a query regarding updation.
1.I invoke a procedure in Oracle called submit thru my Java application.
The submit procedure saves the XML data in the database
and displays this data in a Front End GUI.
2. Now,I make a change in my Java application by adding new elements to the same row.This row now contains additional XML elements.
I would like to display the new row with the new elements in the GUI.
What is a better option for doing the above?
1.Delete the row being shown,save the new row with the changes in the database,and re display it?
2.Or,Update the row dynamically and refresh?
Any suggestions
Thanks,

Thanks,If you delete (it seems to me yours this process is regular and frequent) and re insert the new updated one record then High water mark will cause to scan yours table which may cause to degrade the performance.AFAIK you should go with update.But hold down dont implement it as i suggested lets see what are others solution here which may be more precious then mine.

A query regarding synchronised functions, using shared object

Hi all.
I have this little query, regarding the functions that are synchronised, based on accessing the lock to the object, which is being used for synchronizing.
Ok, I will clear myself with the following example :
class First
int a;
static int b;
public void func_one()
synchronized((Integer) a)
{ // function logic
} // End of func_one
public void func_two()
synchronized((Integer) b)
{ / function logic
} // End of func_two
public static void func_three()
synchronized((Integer) a)
{ // function logic
} // End of func_three, WHICH IS ACTUALLY NOT ALLOWED,
// just written here for completeness.
public static void func_four()
synchronized((Integer) b)
{ / function logic
} // End of func_four
First obj1 = new First();
First obj2 = new First();
Note that the four functions are different on the following criteria :
a) Whether the function is static or non-static.
b) Whether the object on which synchronization is based is a static, or a non-static member of the class.
Now, first my-thoughts; kindly correct me if I am wrong :
a) In case 1, we have a non-static function, synchronized on a non-static object. Thus, effectively, there is no-synchronisation, since in case obj1 and obj2 happen to call the func_one at the same time, obj1 will obtain lock for obj1.a; and obj2 will obtain lock to obj2.a; and both can go inside the supposed-to-be-synchronized-function-but-actually-is-not merrily.
Kindly correct me I am wrong anywhere in the above.
b) In case 2, we have a non-static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a. However, since obj1.a and obj2.a are the same, thus we will indeed obtain sychronisation.
Kindly correct me I am wrong anywhere in the above.
c) In case 3, we have a static function , synchronized on a non-static object. However, Java does not allow functions of this type, so we may safely move forward.
d) In case 4, we have a static function, synchronized on a static object.
Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a. However, since obj1.a and obj2.a are the same, thus we will indeed obtain sychronisation. But we are only partly done for this case.
First, Kindly correct me I am wrong anywhere in the above.
Now, I have a query : what happens if the call is made in a classically static manner, i.e. using the statement "First.func_four;".
Another query : so far we have been assuming that the only objects contending for the synchronized function are obj1, and obj2, in a single thread. Now, consider this, suppose we have the same reference obj1, in two threads, and the call "obj1.func_four;" happens to occur at the same time from each of these threads. Thus, we have obj1 rying to obtain lock for obj1.a; and again obj1 trying to obtain lock for obj1.a, which are the same locks. So, if obj1.a of the first thread obtains the lock, then it will enter the function no-doubt, but the call from the second thread will also succeed. Thus, effectively, our synchronisation is broken.
Or am I being dumb ?
Looking forward to replies..
Ashutosh

a) In case 1, we have a non-static function, synchronized on a non-static object. Thus, effectively, there is no-synchronisationThere is no synchronization between distinct First objects, but that's what you specified. Apart from the coding bug noted below, there would be synchronization between different threads using the same instance of First.
b) In case 2, we have a non-static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a.obj1/2 don't call methods or try to obtain locks. The two different threads do that. And you mean First.b, not obj1.b and obj2.b, but see also below.
d) In case 4, we have a static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a.Again, obj1/2 don't call methods or try to obtain locks. The two different threads do that. And again, you mean First.b. obj1.b and obj2.b are the same as First.b. Does that make it clearer?
Now, I have a query : what happens if the call is made in a classically static manner, i.e. using the statement "First.func_four;".That's what happens in any case whether you write obj1.func_four(), obj2.func)four(), or First.func_four(). All these are identical when func_four(0 is static.
Now, consider this, suppose we have the same reference obj1, in two threads, and the call "obj1.func_four;" happens to occur at the same time from each of these threads. Thus, we have obj1 rying to obtain lock for obj1.aNo we don't, we have a thread trying to obtain the lock on First.b.
and again obj1 trying to obtain lock for obj1.aYou mean obj2 and First.b, but obj2 doesn't obtain the lock, the thread does.
which are the same locks. So, if obj1.a of the first thread obtains the lock, then it will enter the function no-doubt, but the call from the second thread will also succeed.Of course it won't. Your reasoning here makes zero sense..Once First.b is locked it is locked. End of story.
Thus, effectively, our synchronisation is broken.No it isn't. The second thread will wait on the same First.b object that the first thread has locked.
However in any case you have a much bigger problem here. You're autoboxing your local 'int' variable to a possibly brand-new Integer object every call, so there may be no synchronization at all.
You need:
Object a = new Object();
static Object b = new Object();

How to query two data blocks simultaneously?

Dear all,
Need your inputs on the following problem statement...
Existing Functionality:
We have two data blocks A (Parent) and B (Child) in a relationship. Both data blocks refer to different tables.
Data block A is the query data block and for a single record in block A we can have multiple records in block B. Multiple records in block B are shown one at a time after executing a query, this is implemented by using a list item C (belongs to a third block).
For example
Let us say block B can have 5 different types of entries for each record in block A. In this case the list item C will have 5 values corresponding to these entries. Once the query is executed, block B will show the default entry for the queried record in block A. To see other entries for the record user can select the required value in list item C and corresponding entry in block B will be fetched.
Requirement:
Our requirement now is to enable querying upon both data blocks A and B simultaneously. To implement this I replaced data blocks A and B with a single data block X which is based on the join of the two tables referred by the Data blocks A and B earlier. As the fields should allow insert, update, delete operations we did not use a view here.
Issue:
Now the problem is, each record in block A for which block B had multiple entries earlier is now getting listed multiple times because of the join.
I have tried but could not find any solution for this. I would appreciate if any of you can suggest how we can query both blocks simultaneously without affecting the existing functionality.
Thanks,
Amit

I don't understand your requirement in detail. I try to repeat what i understood so far.
You have a master-block A based on a table A and a detail-block B based on a table B. So far so good. You can now query based on conditions just the datablock A, because B is a detail and therefore can only be queryied in context of block A.
Your reuirement is to query on both blocks A and B and find block in B also without giving conditions for the relevant block A.
Is it that ?
What i don't understand, what is block C used for?
An idea for the querying of block B's data: Create Non-database-items items in block A for the search-criteria you need on block B and make them Queryable.
In the PRE-QUERY-trigger on block A build a WHERE-condition if that search-criteria is entered, something like
IF :BLOCK_A.SEARCH_CRITERIA_FOR_BLOCK_B IS NOT NULL THEN
SET_BLOCK_PROPERTY('BLOCK_A', ONETIME_WHERE, 'WHERE PKVALUE IN (SELECT FKVALUE_TO_A FROM TABLE_B WHERE FIELDVALUE=' ||:BLOCK_A.SEARCH_CRITERIA_FOR_BLOCK_B)');
END IF;This would query also records to A for which you want to have the B-records. So you could keep block-structure up to master-detail.
