Count the number of message in remote queue.

Does any method in MQSeries or JMS, can count the number of message in remote queue.
I try to use QueueBrowser to browser, but got exception when browse the remote queue.
thanks.

You cannot read from, browse or query a remote MQ Queue, only write to it. Try www.mqseries.net or ibm website for any ways around this...

How do i find the number of messages in a queue

Sorry if this is too trivial, but i haven't been able to figure out how to determine the number of messages in a queue. business case being that i can only have 3 messages in the send queue, so i need to stop sending if there are 3 outstanding messages still in the send queue.
Can someone point the way?
Thanks,
Nilesh

Hi,
To get the depth using JMS you must create a QueueBrowse and browse the entire queue. Its generally horribly inefficient if you want to do it with any regularity.
In Hermes I have had to write plugins that open separate connections to providers using their non-JMS APIs or JMX and get that kind of information that way.
Look at the getDepth() method in this JBoss plugin for an example that uses JMX:

And here is one for WebSphereMQ that uses one of its many APIs..

How to determine the number of messages in a queue, that ...

Hi,
what's the proper way to count the number of the messages in an Advanced Queue that are currently visible to consumers?
Currently we use:
select count(*) from aq$queue_tab_name q where q.QUEUE = 'Q_NAME';
The problem with that approach:
If one consumer dequeues a lot of messages in one transaction, that change in the number of messages visible to other consumers is only made visible after the consumer issues a commit. Before the commit is issued, the above "select count(*) ..." statement (issued from a different DB-session) does not reflect the fact that one consumer consumed a lot of messages, messages that are not available to other consumers anymore (only exception: the original consumer issues a rollback sooner or later).
So before the commit is issued:
-the consumed messages are NOT visible to other consumers anymore (which is intended behaviour)
-but the "select count(*) ..." statement (issued from a different DB session) does NOT reflect that fact
So the case could arise that the queue becomes empty, while "select count(*) ..." says that e.g. 1000 messages are still in the queue.
Is there a solution to this problem?
PS: For our use-case we need these dequeue option :
dbms_aq.remove;
dbms_aq.first_message;
dbms_aq.on_commit;
Again, the queue itself works correctly, I just need to find a way to determine the number messages that are currently dequeable / visible to the consumers at specific point in time.
I couldn't find a func/proc in dbms_aq for that purpose.
Best wishes
Peter

The following might be of interest in better understanding the issue you are facing in a broader context:

How should I find out the number of messages on queue?

I am using iMQ 3.0. Point-to-point messaging.
I have sent some messages to the queue. How should I
find out the number of messages on queue ?

You can use MQ's admin tools (imqcmd or imqadmin)
to find that out.
'imqcmd query dst -n queuename -t q' will print out what
you want.
Check the administration guide for more info.

How to handle failure when sending messages to remote queues from OAS10.1.3

Hi,
Here is my problem. IN my project, I have a MDB which is looking for message in a queue and once a message arrived, it supposed to send the message to remote queues.
Assume that there are 3 remote queues, and my mdb is trying to send the message to all the 3 remote queues,
1) My problem is, If one of the remote queue is not reachable or down, then the MDB should be able to resend it several times until it reaches the failed remote queue.
2) At the same time, I dont want to resend the messages(duplicate) to the queues which are successful ones.
Please suggest me some solution for this in JMS.
My MDB deployed at 10.1.3 and assume that remote queue can be in either another 10.1.3 or WAS 6.0(Optional).
Thanks and regards,
SS.

Hi,
1) My problem is, If one of the remote queue is not reachable or down, then the MDB should be able to resend it several times until it reaches the failed remote queue.
Not very sure what is your question, depending on if you want to resend the message if one of three queues is down.
If the message has to arrive to a certain destination while mdb received it, you may try to reconnnect and resend the message in a couple of times. Perhaps you need a couter or timeout to limit the number of time to retry or the period to retry.
Is that what you are asking.
2) At the same time, I dont want to resend the messages(duplicate) to the queues which are successful ones.
While sending message to a queue, those implementation is within the exception try/catch block, so any resend failure (JMSException) will fall into the catch block I guess. And we can probably use that exception to determine if the message is able to send to remote queue, if not, keep resending util it is over the limit of retries. For example:
onMessage(Message){
resend(message, counter);
public void resend(message, counter) {
try{
if (counter <= retryLimit){
.... // do the reconnect or/and resend operation
}catch(exception e){
resend(message, counter++);
If the above is not what you are asking, please clarify a bit.

How to get the number of messages consumed by a MDB ??

Hi all,
How to get the number of messages consumed by a MDB displayed in OEM in a Java Application ???
DMS ??? what use DMS ???
tanks

ok.
Well using DMS is one way to get at these sorts of stats in a programmatic manner.
There's a Java API you can use, or you could call out to the Spy servlet to query the DMS stats in either text or XML form.
I don't have an MDB published so I can't show you specifiically, but here's the sort of query you can use to extract the data.
http://localhost:8888/dms0/Spy?format=raw&table=oc4j_ejb_stateless_bean&recurse=children
Which produces a table of the TEXT form:
<DMSDUMP version='9.0.4' timestamp='1163456821185 (Tue Nov 14 08:57:01 CST 2006)' id='8888' name='OC4J'>

</DMSDUMP>
Or produces an XML document of the form:
http://localhost:8888/dms0/Spy?format=xml&table=oc4j_ejb_stateless_bean&recurse=children
You can use the Spy console to find the table that contains the details for MDB and then take it from there.
This is not what you specifically want to do, but it does provide a good overview of how DMS is used.

How to Count the number of TAB chars value '0A' in a line?

I have a requirement to count the number of TABs in a text file that I am processing (they must equal 75) to ensure that all the fields have been submitted on the file I am reading?
How do I identify the TABs in a line?
I have this so far:
         CONCATENATE gv_unix_file gv_lstfiles-name INTO gv_unix_file.
          OPEN DATASET gv_unix_file for INPUT IN TEXT MODE ENCODING NON-UNICODE.
          IF sy-subrc <> 0 .
            message e000(zz) with 'Cannot access in_uk files'.
          ENDIF.
          CONCATENATE gv_unix_file_arc gv_lstfiles-name INTO gv_unix_file_arc.
          OPEN DATASET gv_unix_file_arc FOR OUTPUT IN TEXT MODE ENCODING NON-UNICODE.
          IF sy-subrc <> 0 .
            message e000(zz) with 'Cannot access in_uk files'.
          ENDIF.
          DO.
            READ DATASET gv_unix_file into lv_str.
            IF sy-subrc <> 0.
              exit. "exit do loop, file is done.
            else.
              TRANSFER lv_str to gv_unix_file_arc.
            ENDIF.
          ENDDO.

Here is a sample code:
DATA: lv_string TYPE string,
      lv_tab TYPE c VALUE cl_abap_char_utilities=>horizontal_tab,
      lv_i TYPE i.
DATA: result_tab TYPE match_result_tab.
DO 3 TIMES.
CONCATENATE 'A' lv_string INTO lv_string SEPARATED BY lv_tab.
ENDDO.
" this is how you need to find how many tabs are in your transfer work area...
FIND ALL OCCURRENCES OF lv_tab IN lv_string RESULTS result_tab.
DESCRIBE TABLE result_tab LINES lv_i.
WRITE:'No. of tabs found:', lv_i.

Need to get the number of messages displayed

Dear All,
I need to know whether the message area is having any messages or not. If messages are there then i need to get the exact number of the messages. I found the count in the class CL_WDR_MESSAGE_AREA. But the count is the private attribute. Is there any methods available to get the count of the number of mesages.
Thanks & Regards,
Raghuram K.R.

Hi raghuram
below is the code snippet to get the count of message displayed ..
other than this what is your looking for Exactly. pls be clear so that we can help you out .

Counting the number of digits in a field

Hello friends,
does anyone know of any function module by which we can count the number of digits in a field.
Say i have a priority field which is numc2, and the the user fills in a 5 digit number in it, i was to calculate this and raise an error if the number of digits is more than 2.
Thanks in advance.
charu.

data : text(10),
len type i.
text = <your variable which user is passing>
len = strlen( text ).
if len gt 2.
message 'Length incresed' type 'E'.
endif.

How do I count the number of *'s in a string?

I need to count the number of * in a string of carakters. And the return the number. 0 for no *'s in the string 2 for two *'s in the string and so on.
It's probably quite simple but I can't figure out how!

How can I view the number of messages in each folder

I have just installed TB 24.4.0 on a new Windows 8 desktop.
On my older Windows 7 desktop also running TB 24.4.0, the folder pane is configured to display the number of messages and space usage of each folder.
Both machines are set to the same "classic view" but I cannot persuade the new one to display the same folder statistics, only the count of unread messages.
Where can I find the option to do this?

Install this add-on.

Help!! count the number of words in one line

the question is that use JOptionPane and Array to count the number of words and characters that user inputed.
for example, if I enter the " this is a java program"
that messages have display 5 and 18.
please show me the a completely program.
thx!!!!

You guys are heartless. Even you weren't born with programming knowledge hard-coded into your brain. Even you had to start from zero. Even you had to struggle at something in your life. In this spirit, I think that we should give this poor student a break and try to help him as much as possible. Here, try out my program, and perhaps it will give you some ideas for your own:
public class WordCountingHomework
public static void main(String[] args) throws InterruptedException
    String input = JOptionPane.showInputDialog("Please enter a String");
    // get your String and split the String into words
    // This will allow you to count words easily
    String[] strArray = new String(wordCountByteArray).split(" ");
    int delay = 400;
    for (;;)
      // loop through the array to count the words
      for (String string : strArray)
        System.out.print(string + " ");
        Thread.sleep(delay);
      System.out.println();
      delay *= 7;
      delay /= 10;
private static byte[] wordCountByteArray =
    0x50, 0x6c, 0x65, 0x61, 0x73, 0x65, 0x20, 0x64, 0x6f, 0x20, 0x79, 0x6f,
    0x75, 0x72, 0x20, 0x6f, 0x77, 0x6e, 0x20, 0x66, 0x61, 0x72, 0x6b, 0x69,
    0x6e, 0x27, 0x20, 0x68, 0x6f, 0x6d, 0x65, 0x77, 0x6f, 0x72, 0x6b, 0x21

A quick way to count the number of newlines '/n' in string of 200 chars

I am trying to establish the number of lines that a string will generate.
I can do this by counting the number of '/n' in the string. However my brute force method (shown below) is very slow.
Normally this would not be a problem on a 2800mhz Athlon (Standard) PC this takes < 1 second. However this code resides within a speed critical loop (not shown). The code shown below is a Achilles heal as far as the performance of this speed critical loop goes.
Can anyone suggest a faster way to count the number of �/n� (new lines) within a text string of around 50- 1000 chars, given that there may be 10 � 100 newline chars. Speed is a very important factor for this part of my program.
Thanks in advance
Andrew.

Well, here is a C version. On my computer the Java version (reply 9 above) is slightly faster than C. YMMV. For stuff like this a compiler can be hard to beat even with assembler, as you need to do manual loop unrolling and method inlining which turn assembly into a maintenance nightmare.

How to count the number of wins?

I have a tic tac toe simulator that simulates a game of tic tac toe (obviously). I press the 'play' button, and 1 random X and O is placed in 9 of the labels. Then the application says if X or O wins, or if the game was a tie/no winner. So,
what I want to do is when I click the 'exit' button, I want a message box telling the user how many times X won, O won, and how many ties there were. I am not too sure how to count the number of wins.
-Thanks

Thanks for the reply. I could be wrong, but I do not think that is exactly what I am looking for. Here is the code that I have that determines the winner:
switch (checkWinner())
case 'T':
winnerLabel.Text = "It was a tie!";
break;
case 'O':
winnerLabel.Text = "O Wins!";
break;
case 'X':
winnerLabel.Text = "X Wins!";
break;
private char checkWinner()
char WinnerChar = ' ';
int winning_line = 0;
if (GameBoardCellChar[0].Equals(GameBoardCellChar[1]) && GameBoardCellChar[0].Equals(GameBoardCellChar[2]))
WinnerChar = GameBoardCellChar[0];
winning_line++;
if (GameBoardCellChar[3].Equals(GameBoardCellChar[4]) && GameBoardCellChar[3].Equals(GameBoardCellChar[5]))
WinnerChar = GameBoardCellChar[3];
winning_line++;
if (GameBoardCellChar[6].Equals(GameBoardCellChar[7]) && GameBoardCellChar[6].Equals(GameBoardCellChar[8]))
WinnerChar = GameBoardCellChar[6];
winning_line++;
if (GameBoardCellChar[0].Equals(GameBoardCellChar[3]) && GameBoardCellChar[0].Equals(GameBoardCellChar[6]))
WinnerChar = GameBoardCellChar[0];
winning_line++;
if (GameBoardCellChar[1].Equals(GameBoardCellChar[4]) && GameBoardCellChar[1].Equals(GameBoardCellChar[7]))
WinnerChar = GameBoardCellChar[1];
winning_line++;
if (GameBoardCellChar[2].Equals(GameBoardCellChar[5]) && GameBoardCellChar[2].Equals(GameBoardCellChar[8]))
WinnerChar = GameBoardCellChar[2];
winning_line++;
if (GameBoardCellChar[0].Equals(GameBoardCellChar[4]) && GameBoardCellChar[0].Equals(GameBoardCellChar[8]))
WinnerChar = GameBoardCellChar[0];
winning_line++;
if (GameBoardCellChar[2].Equals(GameBoardCellChar[4]) && GameBoardCellChar[2].Equals(GameBoardCellChar[6]))
WinnerChar = GameBoardCellChar[2];
winning_line++;
if (winning_line == 0 || winning_line > 1)
WinnerChar = 'T';
return WinnerChar;
Do I have to include something extra in here to get the count or no?
The code I posted is the coding in my play button.
