• Job queue and event ADVANCE.

  Hello

  I'm getting to do advanced queues work which could be removed by the use of event in function. For a single message, it seems to work but if I queue of messages more some of them are 'lost' without having been processed. In below code I create job scheduler queue and event. Then I enqueue messages 3 - two immediately after each other and third with 5 delay. Only the first and the third message are processed (and written to the TST_DATA table). In the queue table, it seems all messaged have been processed. RDBMS version is 12.1.0.2.

  Thanks for any response.

  SELECT * FROM TST_DATA;
  

  Hello

  you're right: after two immediate queue operations and a separate queue there are only two lines in the table

  (tested on 11.2.0.4):

  SQL> select * from tst_data;
  
  SCOMMAND
  --------------------------------------------------
  test1
  test3
  

  If you wait just 1 sec after each DBMS_ENQUEUE there are 3 rows.

  Even with a visibility using DBMS_AQ.COMMIT and COMMIT after that each line there are only 2 rows.

  This mechanism using DBMS_SCHEDULER and EVENT_MESSAGE functionality seems to be a bit slow.

  You must specify the option parallel instance for your business:

  DBMS_SCHEDULER.set_attribute ('TST_JOB', 'parallel_instances', TRUE);
  

  You will get then 3 rows, even without a delay of sleep:

  SQL> select * from tst_data;
  
  SCOMMAND
  -----------------------------
  test1
  test2
  test3
  

  Kind regards

• Oracle Streams and CLOB column

  Hello
  
  We use "Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64 bit. My question is "Does Oracle Streams capture, spreads (source capture method) and applies the CLOB column changes?"
  
  If so, is this default behavior? Can we say Brooks to exclude all of the CLOB column (capture-spreading-request) process?
  
  Thanks in advance!

• Grid Control 11 g includes advanced replication management?

  The system that I administer currently Oracle Enterprise Manager 10g Grid Control to General administration, but he had to keep the old based on java Enterprise Manager to manage advanced replication. (All of the databases is currently Oracle 10 g. We plan to upgrade the databases up to 11g Release 2. The context is a central database with 16 knots that have views materialized update-able over them to subsets of the data.)
  
  I do research moving to Oracle Enterprise Manager 11 g. Manage Advanced Replication? Otherwise, what Oracle tool now provide or support for advanced replication management? The URL of a white or manual book or article would be a great help.

  Clark,

  If you do not find yourself still, Yes, he does. OEMGC can set up and manage advanced replication environments: http://oracle.informatik.haw-hamburg.de/server.111/b28326/repoverview.htm#i13140

• Advanced replication monitor

  Hello
  We have advanced replication between two Master set up sites, this configuration also is aimed at DR solution as replication sites located in different cities. My question is that in case of disaster, how can we determine when was the last 'push' that we have obtained from the other site...
  To develop more... For example we have advanced replication between Melbourne and Sydney, and "sydney" goes down... How can we say (sql query) when was the last time we got the 'push' of sydney success in Melbourne...
  and the reasoning for this question must answer the question of Exec which is the scenario of loss of data in Sydney...
  
  Thank you
  Manu

  Hello

  There are probably ways you could accomplish something like this using a combination of opinion of replication queue, but I don't know what either "out of the box" for replication that offers this possibility, I'm sorry.

  Thank you

• Tuxedo of Oracle and Oracle Tuxedo message queue on a virtual machine.

  Hi friends.

  How is it going?

  A small question.

  So let's go live using Oracle Tuxedo 12.1.1.0 with binding distinguished Bulletin Board and Oracle Tuxedo Message Queue 12.1.1.0 on a Virtual Machine (VMWARE) running Oracle Linux 6.2. However, we want to know if there are recommendations or mishaps in which we face before running Oracle Tuxedo on a virtual machine?

  I mean, I wonder if I have to worry about kernel parameters, settings of virtual machine or any other thing that could ruin everything.

  Another question.

  Oracle also provides certification of VMS where Tuxedo Oracle would go on top of the?

  Hi Bruno.

  I'm not sure what you mean with single Liaison Bulletin Board.  I guess you mean a cluster or the MP configuration?  And is it really a clustered or just a single machine of the MP configuration?

  About the configuration, you use Tuxedo services as well or just Tuxedo Message Queue?  The biggest problem with the configuration of the BONE is the IPC resources.  If you do a-c tmloadcf on your UBBCONFIG file, it will help you to determine the required minimum IPC resources.  In general, I suggest configuration much more resources than the minimum to allow for the changes to come and for some of the parameters for heavier loads.  In particular IPC message queue settings are strongly dependent on the load.  So make sure that the maximum message size and the size of the queue are big enough for your expected workload.  You can monitor the slot load using the ipcs command.

  We don't certify virtual machine environment, but support also a long time the VM vendor to ensure compatibility, obviously VMware and Oracle VM who both do.

  Kind regards

• Oracle Streams without link DB

  Hi all
  
  We have an obligation to move data for about 20 tables of a database in a particular network to a database in another network. The database on both sides runs on 11g and has an RAC implementation.
  
  To perform this replication options are here
  
  -Oracle Streams
  -Oracle Golden Gate
  -Export and import Datapump then
  
  We have the following restrictions to make the transfer
  
  -No DB connection cannot be created
  -No additional licenses can be purchased for the purchase of Golden Gate
  
  Subject limitations above still go with Oracle Streams (as I read the oracle documentation, and he says that DB Link is mandatory) or am I just left with the option of datapump
  
  Thanks in advance,
  Jayadeep

• When to recreate queues and tables of the queue in QA?

  When recreate us queues and queue tables when you use Advanced Queuing? Is there an advantage in doing this?
  
  dbms_aqadm.stop_queue)
  dbms_aqadm.drop_queue)
  dbms_aqadm.drop_queue_table)
  
  dbms_aqadm.create_queue_table)
  dbms_aqadm.create_queue)
  dbms_aqadm.start_queue)
  
  Also, can you please let me know what is the difference between the queue and queue table? I'm newbie and not able to get help on that. I had a little of that first we can create the queue table and then create the queue. Any help would be appreciated.

  Why do you want to "recreate" the queues and queue tables?

  Read the documentation of

  DBMS_AQADM.ALTER_QUEUE
  and
  DBMS_AQADM.ALTER_QUEUE_TABLE
  

  and see if you can get out without falling and re - create

  In the contrary case; do some reading on how to manage queues, to drop, modification and creation!

  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14257/aq_admin.htm#i1005956
  and
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14257/aq_admin.htm#i1006297

  If you want to change the payload type, you need to remove the queue and re-create it, in which case read on drop, keep in mind the STOP_QUEUE!
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14257/aq_admin.htm#i1006355

  Similarly for the DROP table queue!
