• Configuring JMS Adpter for remote weblogic JMS

  Hello
  We have SOA and OSB installed on separate computers.
  We use SOA 11.1.1.6.
  I have a requirement to send a JMS weblogic installation message where SOA is installed for weblogic installation where the OSB is installed.
  I understand that I must create a foreign JNDI provider where I need to create the link with the SMC OSB that I created on weblogic SOA.
  
  Now, when I am configuring the JMS adapterit asks me to select the connection to the server app jdev which is the installation of SOA connection it shows all queues and topics
  present on the installation of weblogic SOA but I need to specify the name JNDI Local and remote JNDI name somewhere so the message should go the
  OSB JMS.
  Can you get it someone please let me know how to configure the adapter in this scenario?
  Any help/pointers in this regard are appreciated.
  
  With respect,
  Hard

  Not very clear on your condition. Here's what I understand:
  1. you have a JMS queue in the field of the SOA Suite and another line in the area of the OSB
  2. you want to send messages to the queue JMS SOA field to the field to OSB JMS queue

  First of all don't think that you need a separate queue in the field of the OSB, you can have your proxy service point to the queue JMS in SOA Suite. You can simply use the domain SOA listening address and JNDI names in the service OSB JMS as URI a Proxy endpoint it will read messages directly from field JMS queue to SOA.
  However, if you have messages to copy first to the local OSB JMS queue, I would suggest creating an agent FAS to messages before directly from queue JMS SOA to the queue of the JMS OSB, in this way you will not have to build a composite to forward the message.
  Finally, if you want to forward the messages from the queue JMS SOA to the queue JMS OSB via a composite then you need build two adapters JMS in your composite application.
  JMS adapter to read the messages in the queue JMS SOA domain. (Use a server app connection in jDev which points towards SOA domain admin server and provide the queue JMS JNDI names created in the field of SOA).
  Other JMS adapter to write messages of OSB field JMS queue. (Create another connection of server app in jDev which points to OSB domain admin server and provide the names of the JNDI queue created in the field of the OSB).
  Then you can just put a mediator to take first map JMS messages and send to the second map of JMS

• What happens when "Still waiting for network when starting the computer and logon" is enabled and that the computer is not connected to the network?

  In MMC, I created the group policy and found through web search that computers with mapped network drives can connect better if "always wait for network when starting the computer and logon" is enabled...  So far, it has been very nice to have allowed.  Is no longer mapped network drives see the place as disconnected.  But what happens if the computer is not connected to a network?  Say the wireless router will turn off and your computer always 'wait... '. "turned on, should the user could still log the computer timely?

• How to wait for HTML when ADF Application sends a 'work' screen while Looking Up data space reserved

  Hello world

  I am trying to write test scripts in Openscript for an ADF application that uses Business Intelligence and support partial-Page rendering.  While it generates data, it sends HTML says his 'work', and then re - makes the area after the SQL call to the database ends.  The script passes after receiving the 'work' page and errors because it cannot find the variables that should have been created.

  How can I make the script wait for the actual page?  I looked through the documentation and looked online but I couldn't find anything relevant (or do not know what I'm looking for).

  Any help appreciated.

  Thank you

  Roy

  OK - problem solved.

  OBIEE sends the page indicating that it is looking up until the actual data returned.  There is an option on the Weblogic OBIEE server in the {WEBLOGIC_HOME}/instances/bi_instance/config/OracleBIPresentationServicesComponent/coreapplication_obips1/instanceconfig.xml file that can be defined (for test/debugging) to delay sending the screen holder place 'research'.}

  This should be added to the file XML between the tags.

  600

  True

  The value indicates how many seconds the OBIEE server waits until it sends to the screen "search.

  I hope that this information will prevent hair pulling episodes by others.

• Waiting for CPU: what exactly does that mean?

  Hi all
  
  I worked on this database (11.2.0.3 on AIX 6.1) try to improve the performance of certain lots of an ERP system developed by my company. These are all processes that work very well in other environments, but here the clock times are horrible for the load and I was seeing 10% CPU, 90% CPU waiting for almost every process. This is the last section of a very long trace file where you can see the invisible "wait."
  
  I know not how to do this: if I run something in the OS with a higher priority than to Oracle, what I will get. "Lack of processor" according to me, is the name for it. My question is: what else can cause this? If the OS say that nothing was on the computer, how can I study the root cause?

  don't you think that it is possible that tracing would cause such a huge head?

  Your trace file contains 25 million lines, that is a significant amount of write operations, to be compared with the information that reads one-piece 620K consume dry 4858.
  It is necessary to note that writing in the trace file leads to loss of time only when it is caused between measure of elapsed time from a visit to the database. But even if the write operation is due to the outside to measure the time of the call for a database (for example, information about a call, as FETCH #) it can be inside some call parent and will be included in the duration of the call of the mother.
  If you are interested in the details of this process, I prepare an article on this topic in my blog.

  I would therefore recommend to reproduce a similar load without follow-up.

  This error usually indicates that you have two type of event and bean converter specified or not specified. In your case, which does not seem the case by looking at the source file. You could also paste the contents of your configuration of the directory META-INF/wlevs file?

• 125, hogging threads waiting for lock oracle.jdbc.driver.T4CConnection@5500

  We use DBAdapter in soa suite 11 g (xa thin drivers, AIX platform) to talk to the database. At one point today, we could see the system WLS slows down considerably and thread dumps could see 125 hogging son everyone waits for the next lock:

  Can someone point to this oracle.jdbc.driver.T4CConnection@55005500. Is that a lock on a connection object? If so this means that all 125 discussions were waiting for a single connection? The source of data used has default settings for the connection pool.
  
  I couldn't see any thread thread discharge which States that it is now the same lock, possibly could be a problem with the way thread dump is generated in AIX
  
  Can someone shed some light on this?

  Hello. Grep just for T4CConnection@55005500 in the discharge. You will see the number of threads
  blocked (as you would expect) on this point, but only one thread that already have this object
  locked and uses it. Unfortunately, the thread is suspended in a call to DBMS, so it cannot
  go ahead and release the connection object and let all other threads proceed.
  I has you pointed out only one thread.

• "the db file sequential read" waiting for event slow down an application.

  "the db file sequential read" waiting for event slow down an application.
  
  It is a rather strange problem. There is an update statement that hangs on the wait event 'db file sequential read' and until you restart the database, the query works fine. It happens once a week, usually Monday or after several days of large amount of work.
  
  I checked the processor and is fine, memory is very good, although the SGA and PGA have taken maximum memory. Flow of the disc seems to be ok since each another session on the basis of data looks very good.
  
  I guess that there is a missing configuration to avoid having to restart the database each week.
  
  Any help is greatly appreciated.

  Hello

  If you want same order of the tables as plain exp after reboot just go with ordered hint

  UPDATE item_work_step
  SET user_name = :b1,
  terminal = SYS_CONTEXT ('USERENV', 'TERMINAL'),

  FROM (SELECT /*+ORDERED */ iws.item_work_step_route_id
  FROM user_role ur,
  work_step_role wsr,
  work_step ws,
  app_step aps,
  item_work_step iws,
  item_work iw,
  item i
  WHERE wsr.role_cd = ur.role_cd
  AND ws.work_step_id = wsr.work_step_id
  AND aps.step_cd = ws.step_cd

  and for small tables, you can try adding for example FULL (your) FULL (wsr)

  It can be rewritten in a different way, but it's the fastest way to try how query will be if you rewrite it. Check the explain plan command if certain partially ordered tables are not joined because you can get the Cartesian join, it seems that it will be ok.

  View query result in the em console.

• Stuck "waiting for the printer to be available."

  After initially looking at it's going to print, the printer dialog box displays "waiting for printer to be available" and it's there (even if the printer - inkjet HP series C3800 - is ready).

  Here is what I tried:

  Using the HP utility software on the same computer, I am able to successfully print a test page, which rules out a problem with the printer and its connection to the computer.

  Printing worked normally before moving on to the Sierra. I tried resetting the printing system and add new printer (Sierra recognizes very well). I also tried to run in case disk utility have a permissions problem.

  I'm stumped at this point. Help much appreciated.

  Same story, but with a HP Laserjet P3005dn, specific scenario, the exact symptoms, exact attempts to improve...

• Hi8 thru cam HDV into FCP 7: waiting for timecode

  Hello

  I have a bunch of Hi8 tapes I want to capture on the drive by running through Sony CCD-TR400 on the Canon HV - 20 MBPro & FCP 7.

  I can see the execution in the window capture, but when I hit capture now it gets no further than "Waiting for time code."

  I guess the Hi8 analog, but hoped the Canon with its AV > DV option would treat his way through.

  Any ideas?

  Is the only way to do this would save on tape dv on Canon HV-20 and then capture the disk?

  The best

  Elmer

  Hi8 uses only consumer re-writable (CCFC) timecode that is not readable by the PCF.  In the FCP capture settings, set "Device Control" device not controllable and then use Capture now capture rather than in batches.

• "waiting for encrypted google" does not allow me to open a Web site

  When I try to open lifenews.com, which I visited many times, there is a message saying left down "waiting for encrypted google." I don't even use google chrome? I don't know where to go to get rid of it, I don't want nothing blocked unless I specifically ask to be blocked. I did the research, said it's a blur, said another security settings to uncheck the ssl2 and ssl3. Nothing works. Can someone tell me please how to remove this thing waiting for encrypted google.

  You said blur, which is an add-on. Use the blur, or any extension of similar content filtering? If you think one of them might be the problem, you can test Firefox Safe mode. It is a standard diagnostic tool to disable extensions, hardware acceleration, and a few other advanced features of Firefox.

  Does not work if Firefox: Hold down the SHIFT key when you start Firefox.

  If Firefox is running: You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules

  and OK reboot.

  Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

  Any improvement?
