Broker does not reconnect after db restart

Hi,
we have a enhanced cluster with two brokers running on solaris 10. the ha store is a oracle 10 db. after a db downtime of 10 minutes the cluster could not reconnect to the ha store. we have in the broker logs the following SQLExceptions. it was impossible to use any imqcmd. we had to terminate the two brokers. after starting them everything was running fine, no more exceptions. why do the brokers not reconnect after a db downtime?
regards
ricky

Hi Tom,
near the end of the pasted exception it says: Closed Connection.
i think this is the cause of the failure. this is expected because the oracle data store is down. The problem is, that after the db was back online. the broker continued to throw the same exception. i expect, that the broker throws away the closed connections and reopens new ones to continue his work.

  • WIFI does not reconnect after a standby

    Since I installed "OSX Mavericks" on my MACBOOK AIR, the wireless network does not reconnect after a reboot or standby. I need to disable the wireless and reactive for the connection resumes!
    Thanks for your answer...

    http://carnationsoftware.com/LastA2DPDevice_Mac_Wireless_Problem.html
    Trash your Bluetooth preferences, restart your Mac.
    Open Bluetooth Preferences (Apple Menu, System Preferences, Bluetooth)
    Remove any audio devices that are shown in the upper section of that list.
    Pair your Bluetooth Speaker or headset device and then connect and disconnect it.
    Open /Library/Preferences/com.apple.Bluetooth.plist
    If the LastA2DPDevice item is present, then you know you have just paired a A2DP device. You need to trash your Bluetooth preferences and restart your Mac again.
    The problem is caused by an interaction with Bluetooth and specifically Bluetooth devices that use Advanced Audio Distribution Profile (A2DP) which is used to stream bluetooth audio from devices such as Bluetooth headsets and Bluetooth speakers.
    The problem is caused when the Mac goes to sleep and wakes back up. It tries to connect to the A2DP device that was last used by the Mac. If that device is not powered on or is not in bluetooth range, it will keep trying to connect to that device (for an unknown amount of time). While it is looking for that Bluetooth device, the 802.11 wifi is also looking for the last wireless router or access point and fails to find it.
    Why the wifi is unable to reconnect after waking from sleep is not exactly clear because wifi is a different protocol than Bluetooth. One hint is that it only seems to fail with wireless routers that run on the 2.4 Ghz band. That is the same frequency that Bluetooth uses (even though Bluetooth hops through different smaller bands within that frequency.)
    I do not have the problem when at home and connected to my Airport Supreme Wireless AC router which is running on the 5 Ghz band.
    To prove this, here is what I did...
    1. Go to a location where you are having the sleep / wake wireless problem and take your Bluetooth speakers or Bluetooth headphones with you.
    2. Now while at that location, Connect to the wireless network there.
    3. Turn on the power to your Bluetooth device (speakers or headphones).
    4. Turn Bluetooth on and connect to your Bluetooth device.
    5. Put your Mac to sleep for 45 seconds (that is enough time for the Macbook to shut down power to Bluetooth.)
    6. Wake your Mac back up and you will notice that there is no problem reconnecting back to the wireless network.
    7. Now turn OFF the power to your Bluetooth device and put your Mac to sleep for 45 seconds.
    You will see that your MacBook will not connect back to your wifi wireless network after it wakes from sleep.
    That is because it is looking for your Bluetooth device that it cannot find.
    Note that this test is only valid if you are using a Bluetooth device that uses the A2DP protocol. I did my tests with a Bose Soundlink Mini speaker.
    I am connecting to a Netgear N300 Wireless Router (WNR2000)

  • Airport Extreme in extender mode does not reconnect after main router reset.

    I have an Airport Extreme 4th Gen (extender). set to extend the signal from an Airport Extreme 5th Gen (main).  Whenever the main router resets (after reconfig, etc) the extender does not reconnect.  I would have to restart the extender before it will connect again to the network.  However, my Airport Express set to extend will automatically reconnect.  Is this a settings issue?  Please advise. 

    Ok, well I am hoping you are not doing a re-config of your 5'th gen all the time? This should only be done very rarely... we're talking like less than once a year for many people.  Unless there's something else going on there, I wouldn't worry about it if you have to power-cycle the 4'th gen once in a few blue moons.

  • External hard-drive does not reconnect after sleep

    Hi everyone
    I am trying to use my Energy Saver to SLEEP my iMac after 1 hour. It goes to sleep no problem, but on wake-up, my external USB hard drive does not reconnect. There is also an error message that I didn't disconnect the drive properly. I fear this may be one of Mac OS X's "features". Has anyone encountered the same thing?
    On a side note, I also find that my USB keyboard does not always reconnect as well. I use a windows USB mouse that I have connected to wake it from sleep, however my USB keyboard (the small one for Macs), sometimes does not allow me to type unless I unplug it and back in.
    Another point of note is that both the HD and the keyboard are connected to the iMac through a 7 port USB hub.

    r_dizzle wrote:

    I think this might be the issue. If the iMac is waking back up, it will likely be waking up this HUB, but the HUB might not be re-initialising the connection between OS X and the external drive or the keyboard.
    After waking the iMac, if you unplug the external drive from the HUB, then plug it back in again, does OS X pick it up again? Have you tried plugging the external drive directly into the iMac and then testing what the result is?
    If you read back on what you've said, you pointed out that you have a USB mouse that you use to wake the iMac from sleep. Is this mouse directly connected to the iMac? If so, it surely can't be a coincidence that a directly connected USB device can wake the iMac from sleep, but any USB devices connected to the iMac via a USB HUB cannot.
    I would suggest you test the drive as it is directly connected to the iMac. I would complete the same test with the keyboard too. I think you'll find it's the USB HUB.
    I hope this helps.

  • Airport does not reconnect after standby...

    Is anyone having issues w/ wireless not reconnecting after standby? In order to resolve the problem, I have to turn airport off then back on. Most of the time I can get back on using on/off method, but seldomly I have to reboot. This is my config:
    SSID is not broadcasted, using capital letters and numbers for SSID Name.
    WPA TKIP set for router encryption. WPA Personal selected on Airport.
    I don't seem to have this problem on my Macbook running Leopard, so I'm pretty sure it's hardware/driver related to my Macbook Pro. I have to keep tabs on this, but I almost think this problem does not appear when a network SSID is broadcasted and/or unecrypted. It could be my imagination but not sure.
    Any ideas or same issues out there?

    I always have the same problem; I assume it has something to do with the fact that I regularly switch my cable modem to "standby" when done surfing the internet. Seemingly Airport loses the signal (or whatever) because the modem isn't feeding a signal being in standby mode? When I turn the modem back on, I have to turn Airport back on as well. So far, I've just felt it to be a small inconvenience.

  • Apple wireless mouse does not reconnect after changing batteries

    The wireless mouse on my iMac quit working after I changed batteries. There was no response to mouse clicks, or movement, or scrolling. Eventually I connected a USB mouse, did an orderly shutdown of the system, rebooted, and the mouse started working again.
    The long story ...
    The first time I encountered this problem was the first time I changed batteries in the Apple Wireless Mouse that came with the iMac 3.06 GHz Intel Core 2 Duo I purchased in January 2010. (The OS is 10.6.2 without updates.) I switched the mouse on, the green light on the bottom of the mouse blinked for awhile (at least a minute), but clicking or moving the mouse got no response. The new batteries were Eneloop 1.2v rechargeables. I tried clicking and moving the mouse several times over a period of ten or fifteen minutes, nothing.
    I started searching the web for clues about what to do and maybe a half hour or so later I tried the mouse again and it worked.
    A few days later I wanted to see if the problem was reproducible. I don’t remember now whether I removed the batteries and reinserted them or just power cycled the mouse, but again the mouse quit working. The green light would blink for awhile, about a minute, then would go off completely. I took this to mean the mouse was searching for the Bluetooth network, not finding it, and giving up. Over the period of half an hour or more I tried switching the mouse off and back on several times. The green light would blink, but nothing more.
    I started searching for tips about reconnecting an Apple wireless mouse after changing batteries. I ran across a (2005) discussion on MacRumors forums titled “Wireless mouse troubleshooting problem...” The symptom was a little different, the mouse was partially functional. In this discussion some contributors thought weak batteries could be to blame. So I replaced the rechargeable batteries with new alkaline batteries. Still no go.
    I attached a USB mouse and looked at the Bluetooth preferences pane. I was surprised to see the Apple Wireless Mouse was listed there with status paired and connected. Still at this point switching the mouse off and on would produce blinking light on the mouse, but no functionality.
    I tried various things in the Bluetooth preferences to see if I could get the mouse connection to restart. When I tried to delete the mouse connection there was an alert saying this was the only mouse connected, was I sure I wanted to disconnect. I said yes, but nothing changed in the Bluetooth preferences pane. I tried unchecking the Bluetooth “On” box, etc. Eventually I only succeeded in losing response to the keyboard as well.
    I attached a USB keyboard, shutdown the system, and rebooted. I didn’t know if having the USB keyboard and mouse plugged in would interfere with the wireless devices, but it did not. After the reboot both the wireless keyboard and the mouse were functional again.
    Since then I have tried removing the batteries briefly a couple of more times to see if the problem would recur. I actually put the rechargeable batteries back in. Both times the connection was remade as soon as I clicked the mouse. I also now have seen the Apple support article about setting favorite Bluetooth devices http://support.apple.com/kb/TA21371 . I'll try that if this issue comes up again.

    Hi, is this a question" Post?
    or are you just offering an insight into your Mouse Issue?
    Generally and at times we all have little idiosyncrasies appearing with the running of our Macs.
    I use the same Logitech BT with my MBP. MB & iBook..(not at the same time) Only ever had one issue
    and the cure was to completely Delete the mouse from BT -> Repair Permissions & Reboot then Re Install the BT mouse..Ihave just put a new set of batteries in the Logitech (only 2nd set ever)...L

  • Express does not reconnect after reboot of Extreme

    My extreme is conencted (via ethernet) to my router (bridge mode)
    My Express is connected to Extreme to expand wireless network (bridge mode)
    However when i reboot the extreme, the Express is no longer visible
    I have to reboot as well. is this normal?
    Also, logically (as per above config) the extreme & express are part of ONE wireless network
    So a device conected will "roam" between the 2 as if it's only 1 wifi point (?)
    However when i connect a wireless security camera, it shows me express & extreme seperately (eventhough same name & login)
    and I have to choose to which one to connect.
    IThis means if it's connected to Express & Express stops working, then
    it will NOT got directly to the extreme (eventhough it's well in range)
    Plsd to hear

  • WIFI does not reconnect after MBP sleeps

    When my new MBP Retina wakes up the wifi dies not reconnect.  I have to "Turn WIFI off" and back on again.  My late 2011 works without a problem on the same netowrk.  I have been to an Apple Genius four times.  I have even returned the MBP and got a new one. Same problem....
    Any suggestions.  Could it be the Linksys wifi router? SOuld I get an Apple AirPort Extreme????
    THanks

    I can not believe it, a new wifi router fixed it (so far)

  • Airport Extreme "N" does not reconnect after MBP wakes from standby/sleep

    I have a closed network and do not have any problems with the new AirPort "N" base station except this one. When I open the lid on MBP the computer does not pick up the signal. I have my closed AirPort network in my list of Preferred Networks and yet I have to choose "Other..." from the drop down menu and type in the network name and password before to get it to connect. I do not have this problem on my PowerBook so I have only to assume that I have an incorrect setting on my MBP. Any suggestions? Thank You in advance.
    MacBook Pro 15" 2.4Ghz 160GB HD   Mac OS X (10.4.10)  

    I had this problem on one of my Airport N units. I deleted the base station from the preferred networks and also from the (I think) two locations from the keychain.
    I then connected again and had the Airport added to the keychain again and since then I haven't had the problem.

  • ICloud mail does not reconnect in Mail application on MacBook Pro after disconnecting and reconnecting iPhone or after sleep

    iCloud mail does not reconnect in Mail on my MacBook Pro after sleep or after disconnecting and reconnecting my iPhone. This only happens when I use my iPhone as a 3G-modem and not when I am on Wi-Fi. The only solution seems to be to quit the Mail-application and restart it again. Then Mail reconnects to iCloud.

    Hi horstp,
    Given your description of the issue (works on other Macs), it may be worth trying to set up that account by itself in a new test user on the iMac to see if it can be isolated to a user-specific file. You may find the following article helpful:

  • Site does not load after some minutes of creation or after restart the server

    Hello,
    I have been asked to create a test enviroment identical to the production enviroment. So, what I did was:
    Backed up the production web application's content database: Prod_WSS_ContentDB
    Created new test servers (domain controller, sql server and sharepoint 2013 server) in a new, completely isolated, network environment, without any connection with the production environment (specifically Azure)
    Created a new web application in test environment with a new content database.
    Dismounted the new content database with powershell: Dismount-spcontentdatabase Test_WSS_Content
    Copy the Prod_WSS_ContentDB database to the test sql server and restored it with Management Studio.
    Mount the Prod_WSS_ContentDB databe to the web application with powershell:
    Mount-spcontentdatabse Prod_WSS_ContentDB -WebApplication http://testsp/
    Then, when I type http://testsp in the browser it redirects me to http://testsp/SitePages/Home.aspx
    and the site loads exactly as the production environment.
    But, after some minutes, or if I restart the Sharepoint Server, when I navigate to
    http://sitesp I am redirected to http://testsp/SitePages/Home.aspx
    as expected, but the site does not load, the browser just show a complety blank page.
    The Central Administration site loads normally.
    Trying to fix it I found that if I dismount the content database Prod_WSS_ContentDB, then mount the test database Test_WSS_Content,
    then navigate to the site, dismount Test_WSS_Content and finally mount again Prod_WSS_ContentDB, the site loads normally, no blank page, but after some minutes or if I restart the same happens again.
    For the error event I receice in event viewer it seems that the problem is related to database. I have not found a solution for this error... How can I solve  this?

  • PCI wireless card does not work after restart - FM2-A55M-E33

    Installed TP-LINK WN751ND wireless PCI card onto FM2-A55M-E33 motherboard. The card works fine after cold start, but does not work after restart. Windows recognises the card, but it gets code 10, cannot start.
    BIOS is updated (v.11.1), as well as drivers and Windows 7 64.
    I suspect that this might be the issue: Incorrect ASPM Transitions on the GPP Interface as found in ChipsetMotherboard_TechDocs/48671.pdf on AMD's official support site.
    Does anyone know more about this issue?

    Great! I've done that and now my card shows up. Thing is, when I try to get an IP address, it won't work. Here is the command output:
    ieee80211 phy0: wl_ops_config: change monitor mode: false (implement)
    ieee80211 phy0: wl_ops_config: change power-save mode: false (implement)
    ieee80211 phy0: wl_ops_bss_info_changed: qos enabled: false (implement)
    And then it times out and no IP is assigned. The thing is, wpa_supplicant stays alive after this time out, and I am unable to kill it (killall -9 wpa_supplicant won't kill it). At this point if I try to reboot the machine, it will stop at 'Rebooting' and won't go anywhere. If I turn off the wireless card in its switch Linux crashes. If I try to get an ip again (by running dhcpcd) the command will hang and not return to the shell anymore.
    I am unable to find any useful information in the logs.
    Got any more suggestions?
    Thanks! (And sorry to disturb so much)

    Hello,
    My config is OSX 10.9.1 new macbook pro 13 retina (2014).
    The wifi does not reconnect automatically when waking up from sleep mode since I have a Bluetooth apple magicmouse.
    It was not the case before I bought the BT mouse.
    Is this problem between Wifi and bluetooth coming from the OS?
    Is there a fix already available or scheduled?
    Thanks

    Hello alexandrefromfrance
    Check the Symptom: The network connection drops unexpectedly section for steps on what to do when your MacBook Pro does not connect after waking from sleep. I have also quoted the section on troubleshooting the issue as well.
    Wi-Fi: How to troubleshoot Wi-Fi connectivity
    http://support.apple.com/kb/HT4628
    Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
    After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
    After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
    Solution
    Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
    Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
    Choose System Preferences from the Apple menu.
    Choose Network from the View menu.
    Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
    Click the TCP/IP tab from the top of the screen.
    Click the "Renew DHCP lease" button.
    Select the Wi-Fi tab and view your Preferred Networks list.
    Select each network and click the minus sign to remove those networks from your Preferred Networks list.
    Click OK and close the Network preferences.
    Remove your stored network passwords using the Keychain Access Utility.
    Open Keychain Access from /Applications/Utilities. Your window will look like this:
    Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
    Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".

Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
    Restart your computer.
    Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.

    -Norm G.

  • Card slot does not work after update (14/10/2011)

    Card slot does not work after yesterday update (14/10/2011)! It works with my SD card month ago, but now it dosn't!!!
    MacBook Pro 13 OS ver. 10.6.8

    Thanks for your suggestion. I downloaded OnyX and ran the cleaning function. After restarting, I opened Help and once again the first screen appeared fine. But again most of the links did not work, though those under the "What's New" heading did work. I might add that I had previously tried a variety of suggestions posted in another thread, which included deleting from the caches folder in Home>Library several files such as com.apple.helpui and help.plist in the Preferences folder. (As noted in my previous post this evening, I also created another user but that also did not have any effect.) Any other ideas? Thanks
