• SQL Server: Is it possible to prevent SQL Agent from failing a step on error?

  - by franklinkj

  I have a stored procedure that runs custom backups for around 60 SQL servers (mixes 2000 through 2008R2). Occasionally, due to issues outside of my control (backup device inaccessible, network error, etc.) an individual backup on one or two databases will fail. This causes this entire step to fail, which means any subsequent backup commands are not executed and half of the databases on a given server may not be backed up. On the 2005+ boxes I am using TRY/CATCH blocks to manage these problems and continue backing up the remaining databases. On a 2000 server however, for example, I have no way to prevent this error from failing the entire step: Msg 3201, Level 16, State 1, Line 1 Cannot open backup device 'db-diff(\PATH\DB-DIFF-03-16-2010.DIF)'. Operating system error 5(Access is denied.). Msg 3013, Level 16, State 1, Line 1 BACKUP DATABASE is terminating abnormally. I am simply asking if anything like this is possible in SQL 2000 or if I need to go in a completely different direction.

• Why isn't sox able to convert to mp3?

  - by marue

  I installed Sox, i installed lame-398, but sox is not able to convert any file to mp3. It fails with the messages: ./../sox FAIL util: Unable to load LAME encoder library (libmp3lame). ./../sox FAIL formats: can't open output file `funktech.mp3': How can i check if lame has been installed correct? How can i get sox to find the mp3Library? edit: I did not install sox at all, it works without installing directly from the commandline. Lame was installed by following the instructions on their site: ./configure make make install which results in the following files being found in /usr/local/lib/ : libmp3lame.dylib, libmp3lame.la, libmp3lame.a Maybe symlinking libmp3lame.la, which is marked as executable, to /usr/bin would help?

• Exim - Sender verify failed - rejected RCPT

  - by Newtonx

  While checking on Exim's log messages I found many entries of the following message "Sender verify failed" "rejected RCPT" ... I 'm not an exim expert... I'm afraid Exim is not delivering 100% emails to recipients, because our Email Marketing Application its getting a lower OPEN RATE. Can someone helpe understand this log messages? Is it my server saying "No Such User Here" or a remote server? 174.111.111.11 represents my server IP.

• Some sites won't load on Ubuntu/Mint

  - by Or W

  I have a REALLY weird problem with either my network or my OS. Last week I've suddenly had difficulties loading some websites or even more odd some parts of different websites. For example, I could load gmail.com, login and view the list of emails in my inbox but when I clicked one of them it would just time out. Another example is http://www.ynet.co.il, I can view the home page but going into any one of the articles fails (times out). I've tried Chrome, Firefox and Opera, all fail the same way. If I take a URL of a page I cannot load via the browser and try to wget it though the console I get the file just fine. I've formatted my machine (Used to run Ubuntu 13.04) and installed Mint Linux this time, it worked fine for a few days and now, again, having the same exact issues. Important to note that I have other machines connected either directly or via Wi-Fi to the router and they are all working fine (two win7 machines and 1 raspberry pi). Another strange behavior is that I can ftp or ssh to remote machines but cannot send files via ftp (times out) even if I set passive mode ON and when using ssh I can do just about anything but I cannot paste text into the remote machine, for example if I nano a file on the remote machine and try to paste anything from my clipboard it freezes. What I've tried so far: Disable IPv6 on the networking admin (and on firefox disabling ipv6 on the about:config page) Changing the port and the network cable I went to the store and bought a new standalone PCIe network adapter Connected my win7 laptop using the same cable and router port (sites that were not working on my Mint are working just fine on the win7 machine) Loaded Mint from a livecd, got the same result Tried changing the MTU (was 1500, tried 1492) Some observations: When I clear my browser cache and go to facebook.com for example, the homepage loads but I fail to load any profile/group page. If I refresh facebook.com homepage a couple of times it stops and fails to load until I clear my browser cache. I changed the chrome cache folder permissions to 0777 but that did not help. When I run netstat -n I see A LOT of connections that are in 'FIN_WAIT' mode (I'm guessing that's when I try to refresh pages that are not working and timing out), I have no idea what it means or if it helps anyone figure out what's wrong. The sites that are not loading correctly are always that same, they don't vary or anything and they fail to load exactly the same way on all three browsers that I've tried. When I Googled 'Ubuntu some sites not loading' I see a huge amount of complaints just like mine, but none of them that I could find actually says what the problem is or how they fixed it. Technical stuff: netstat -n ps aux netstat -nr

• Mercurial not receiving push

  - by Jeffrey04

  I have a mercurial web-frontend (hgwebdir.cgi) installed on a server, and an installation of nginx was installed in front of it as a reverse proxy to the web-frontend as my friend suggested. However, whenever a large changeset is pushed (via a script), it would fail. I found an issue ticket @google-code that describe similar problem, and there is a solution that says (#39) So the server side answer is: don't send the 401 back early. Be as slow/dumb as 'hg serve' and make the hg client send the bundle twice. How do I do that? My current nginx config location /repo/testdomain.com { rewrite ^(.*) http://bpj.kkr.gov.my$1/hgwebdir.cgi; } location /repo/testdomain.com/ { rewrite ^(.*) http://bpj.kkr.gov.my$1hgwebdir.cgi; } location /repo/testdomain.com/hgwebdir.cgi { proxy_pass http://localhost:81/repo/testdomain.com/hgwebdir.cgi; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_buffering on; client_max_body_size 4096M; proxy_read_timeout 30000; proxy_send_timeout 30000; } From the access log we keep seeing 408 entries incoming.ip.address - - [18/Nov/2009:08:29:31 +0800] "POST /repo/testdomain.com/hgwebdir.cgi/example_repository?cmd=unbundle&heads=73121b2b6159afc47cc3a028060902883d5b1e74 HTTP/1.1" 408 0 "-" "mercurial/proto-1.0" incoming.ip.address - - [18/Nov/2009:08:37:14 +0800] "POST /repo/testdomain.com/hgwebdir.cgi/example_repository?cmd=unbundle&heads=73121b2b6159afc47cc3a028060902883d5b1e74 HTTP/1.1" 408 0 "-" "mercurial/proto-1.0" Is there anything else I can do on the server because solving it on the server side is preferable :/ Further Findings Bitbucket seems to have this solved ( Check liquidhg bitbucket project and the Diagnosis wiki page ) on the server side, can't find the config anywhere though :/ What happens next varies depending on your server. Some servers refuse the BODY, simplying closing the pipe from the client and causing Mercurial to fail. Some, like Apache (at least the way I configure it, and that could be part of the problem) and nginx (they way BitBucket.org configures it), accept the BODY, though it may take a few retries. Bottom line: if Mercurial doesn't fail the push, it sends the changeset data at least once to a server that has already told it it lacks credentials (more on this at Blame). Assuming Mercurial is still running, it resends the "unbundle" request and data, this time with authentication. Finally, Apache accepts the data successfully. Nginx, OTOH, at least under BitBucket's configuration, seems to reassemble the previous body (the one that lacked authentication) and somehow keep Mercurial from re-sending the whole body.

• Apache doesn't autostart because vpn isn't up yet.

  - by Col. Shrapnel

  I have a FreeBSD8 server, and VPN connection to my ISP. I use mpd5 and it works fine. A have an Apache server whch works fine, if I start it manually, after VPN is get up. But when I add it to rc.conf autostart, it fail to start, saying (49) can't assign requested address: make_sock could not bind to address I suppose it's because VPN isn't up yet and no IP address assigned to the interface which i set in the Listen directive in the httpd.conf. If i set Listen to the existing 127.0.0.1, it fail to serve wan requests. Is there a solution, either to delay apache autostart or configure it some different?

• Force failover a Cisco ASA

  - by user974896

  I have two ASA in a lan state primary\secondary configuration. None of them have "failover active" or "no failover active" in their configuration. Would it be proper to failover in a manner such as: Log into console of primary unit and issue "failover lan state secondary", log into the console of the original secondary unit and issue "failover lan state primary". To fail back simply reverse the process or Log into the console of the primary unit and issue "no failover active", log into the console of the original secondary unit and issue "failover active". To fail back issue "failover active" on the original primary (now secondary) unit, and "no failover active" on the now primary unit. I do not like the second method because it adds configuration directives that were not in place before. Will the first method work?

What could be the reason for this failure? What is the problematic definition for the certificate? Thank you in advance!!!

• Is there a program that compares image files and reports if they are exactly the same pixel-wise?

  - by Nathaniel Drake

  I'm making a regression testing suite for some rendering software. I need to be able to load an image file (PNG or TGA, ideally) and compare the pixel values to a standard approved image. I'd like it to be command line driven too, so I can make a batch file to run all the tests. All the compare utilities I have found so far either show differences (I just need it to fail if they are different) or compare all the bytes, meaning that meta-data will trigger a fail. Anyone got any suggestions? I am not a coder, and can only barely cobble a batch script together. Thanks for any suggestions.

• window.requestFileSystem fails/events firing multiple times in PhoneGap Cordova 3

  - by ezycheez

  cordova 3.1.0-0.2.0 Droid Razr M Android 4.1.2 Windows 7 New to PhoneGap/Cordova. Running one of the filesystem demos from http://docs.phonegap.com/en/3.1.0/cordova_file_file.md.html#File. Using "cordova run android" to compile the code and run it on the phone attached via USB. Problem #1: When the app first starts I get alert("1") twice and then nothing else. Problem #2: When I kick of the code via the button onclick I get the following alert pattern: 1, 2, 2, 3, 3, 4, 6, 5, 7, 4, 6, 5, 7. Some of that makes sense based on the code flow but most of them are firing twice. I'm suspecting problem #2 is being caused by some asynchronous calls hanging out from the first attempt but no matter how long I wait those events don't fire until I kick of the code via the button. So why is the requestFileSystem call failing even though it is waiting for deviceready and why is the other code getting intermingled? Any thoughts are appreciated. <!DOCTYPE html> <html> <head> <title>FileReader Example</title> <script type="text/javascript" charset="utf-8" src="cordova.js"></script> <script type="text/javascript" charset="utf-8"> // Wait for device API libraries to load // document.addEventListener("deviceready", onDeviceReady, false); // device APIs are available // function onDeviceReady() { alert("1"); window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail); } function gotFS(fileSystem) { alert("2"); fileSystem.root.getFile("readme.txt", null, gotFileEntry, fail); } function gotFileEntry(fileEntry) { alert("3"); fileEntry.file(gotFile, fail); } function gotFile(file) { alert("4"); readDataUrl(file); alert("5"); readAsText(file); } function readDataUrl(file) { alert("6"); var reader = new FileReader(); reader.onloadend = function (evt) { console.log("Read as data URL"); console.log(evt.target.result); }; reader.readAsDataURL(file); } function readAsText(file) { alert("7"); var reader = new FileReader(); reader.onloadend = function (evt) { console.log("Read as text"); console.log(evt.target.result); }; reader.readAsText(file); } function fail(error) { alert("8"); console.log(error.code); } </script> </head> <body> <h1>Example</h1> <p>Read File</p> <button onclick="onDeviceReady();">Read File</button> </body> </html>

• HDFS datanode startup fails when disks are full

  - by mbac

  Our HDFS cluster is only 90% full but some datanodes have some disks that are 100% full. That means when we mass reboot the entire cluster some datanodes completely fail to start with a message like this: 2013-10-26 03:58:27,295 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: java.io.IOException: Mkdirs failed to create /mnt/local/sda1/hadoop/dfsdata/blocksBeingWritten Only three have to fail this way before we start experiencing real data loss. Currently we workaround it by decreasing the amount of space reserved for the root user but we'll eventually run out. We also run the re-balancer pretty much constantly, but some disks stay stuck at 100% anyway. Changing the dfs.datanode.failed.volumes.tolerated setting is not the solution as the volume has not failed. Any ideas?

• Network adapters reliability

  - by casey_miller

  Can you help me with understanding of reliability of network adapters. Most of the time servers do have at least 2 NIC's bonded to provide sort of a HA for it. So in case of one NIC fails, the second would still do the job. I wonder which factors work when you use network adapters. I know that, the most important and weakest part of any computer system is: storage (i.e HDD). but how reliable actually network adapters are? There are more expensive ones, and cheaper adapters. In which cases do they actually fail? In what circumstances. May it be a intensive usage of them Time when it's on In your experience how often you found yourself changing NIC's due to their fail? Or just what's the typical lifetime of commodity NIC's? thanks.

• Why am I getting 'undefined method' exceptions when executing 'run_list add', 'run_list remove' and 'rackspace server delete'?

  - by Peter Groves

  [Originally posted this to opscode forum, got no response] I’m testing out a free hosted chef-server account and multiple subcommands are failing with ‘Unexpected Errors’. Perhaps my version and the server version are incompatible? OS: Ubuntu 12.04LTS Local Chef: 10.12.0 (Installed through gem) Local Ruby: 1.8.7 Also, the workstation machine has been manually configured, but the client(s) I’ve been experimenting with are launched with the Rackspace plugin (using ‘knife rackspace server create…’) The problem commands seem to fail when talking to the host chef-server, however, before it ever tries to modify the client, so I don’t believe that’s where the problem exists. The virtual-servers that are launched by ‘knife rackspace server create’ are launched properly but then deleting them with knife fails. If I include a recipe in the run_list when I create the server, the recipe is properly added to the run_list. If I try to add it later or remove the one that there server was initialized with, those commands fail. Here is the output of a few relevant commands (with stacktraces): https://gist.github.com/7100ada3fd6690113697

• Installation fails after period of time

  - by Jack Marchetti

  I'm running Windows 7 64 bit, Ultimate. I'm running into a problem where, if my computer is on long enough, I am unable to install any software. For example, if I reboot and try to install something, for the most part, it will succeed. if I try and install something after a few hours/days, it will always fail. Sometimes stating that "a previous install failed..." or "an install is already taking place..." even though there is nothing being installed. This also seems to be making my Windows updates fail at a pretty regular rate. Any ideas?

• Server drives: 2.5" SCSI less reliable than 3.5" ?

  - by Bill

  Just had an HP 2.5" SAS 10k drive fail on a RAID5 array after about 2.5 years. It made me wonder if this was a fluke or an indication that 2.5" drives are less reliable than 3.5" SAS drives. I've had many 3.5" SAS drives running for many years without any issues (knock on wood). I would think that smaller drives would generate less heat and therefore be more reliable, but couldn't find any evidence of this. I realize all drives will eventually fail and that it's a crap shoot with any particular model, but was hoping someone could point out some related studies or comment on the SCSI drive sizes they've found to be most reliable in servers. Thanks.

• Remote Desktop Problem on Windows Server 2008 R2

  - by lukiffer

  Revised this question to be more concise, consolidating several revisions. Symptoms: From a domain-member Windows 7 Client: Domain credentials to a domain controller = success Domain credentials to a member server (by hostname or FQDN) = success Domain credentials to a member server (by IP) = fail Local credentials to a member server (by either) = success From a non-domain-member Windows 7 Client: Domain credentials to a domain controller = success Domain credentials to a member server = fail Local credentials to a member server = success (Identical behavior from a Mac RDC 2.1 client) Server Configuration Details: Windows 2008 R2 Datacenter w/ SP1 The domain in question is a subdomain of a Windows 2008 domain (forest root). Root has DCs in both Site A and Site B, subdomain only has DCs in Site B. RDP is operating normally on all root member-servers and DCs. No remote desktop settings are defined by GPOs. Network level authentication is enabled; all clients are compatible and the certificate exchange/SSL handshake completes successfully. Not catching any errors in netlogon log.

• Linux software RAID6: 3 drives offline - how to force online?

  - by Ole Tange

  This is similar to 3 drives fell out of Raid6 mdadm - rebuilding? except that it is not due to a failing cable. Instead the 3rd drive fell offline during rebuild of another drive. The drive failed with: kernel: end_request: I/O error, dev sdc, sector 293732432 kernel: md/raid:md0: read error not correctable (sector 293734224 on sdc). After rebooting both these sectors and the sectors around them are fine. This leads me to believe the error is intermittent and thus the device simply took too long to error correct the sector and remap it. I expect that no data was written to the RAID after it failed. Therefore I hope that if I can kick the last failing device online that the RAID is fine and that the xfs_filesystem is OK, maybe with a few missing recent files. Taking a backup of the disks in the RAID takes 24 hours, so I would prefer that the solution works the first time. I have therefore set up a test scenario: export PRE=3 parallel dd if=/dev/zero of=/tmp/raid${PRE}{} bs=1k count=1000k ::: 1 2 3 4 5 parallel mknod /dev/loop${PRE}{} b 7 ${PRE}{} \; losetup /dev/loop${PRE}{} /tmp/raid${PRE}{} ::: 1 2 3 4 5 mdadm --create /dev/md$PRE -c 4096 --level=6 --raid-devices=5 /dev/loop${PRE}[12345] cat /proc/mdstat mkfs.xfs -f /dev/md$PRE mkdir -p /mnt/disk2 umount -l /mnt/disk2 mount /dev/md$PRE /mnt/disk2 seq 1000 | parallel -j1 mkdir -p /mnt/disk2/{}\;cp /bin/* /mnt/disk2/{}\;sleep 0.5 & mdadm --fail /dev/md$PRE /dev/loop${PRE}3 /dev/loop${PRE}4 cat /proc/mdstat # Assume reboot so no process is using the dir kill %1; sync & kill %1; sync & # Force fail one too many mdadm --fail /dev/md$PRE /dev/loop${PRE}1 parallel --tag -k mdadm -E ::: /dev/loop${PRE}? | grep Upda # loop 2,5 are newest. loop1 almost newest => force add loop1 Next step is to add loop1 back - and this is where I am stuck. After that do a xfs-consistency check. When that works, check that the solution also works on real devices (such a 4 USB sticks).

• php.ini settings change not taking effect for large file uploads

  - by user51347

  My server was just reprovisioned, and my application which uploads large (100M+) files now breaks upon re-installation. the symptom is quite consistent : smaller files (8mb in my tests) upload just fine. Larger files cut off at quite close to the same point every time given a particular computer. a file that fails at 26% will fail at just about the same every time. One that takes 1:40s to fail will take within 2 seconds of that every time, before failure. I have set my php.ini settings extravagently : post_max_size = 512M upload_max_filesize = 512M max_input_time = 3600 max_execution_time 3600 Is there possibly a setting at the Apache Level which would override PHP?

• "ssh root@server" hangs indefinitely long

  - by Thibaut

  Hi, Sometimes my ssh client will take forever to login. This happens when the server is not responding (overloaded, killed processed, ...). My automated scripts will then fail because the ssh process will never exit. Is there a ssh configuration value to set a timeout in order to fail if ssh can't login after a predefined number of seconds? I know there are knobs on the server side, but I have to set this on the client side as the sshd process is not responding, or responding incorrectly. Thanks!

• How to gain accurate results with Painter's algorithm?

  - by pimvdb

  A while ago I asked how to determine when a face is overlapping another. The advice was to use a Z-buffer. However, I cannot use a Z-buffer in my current project and hence I would like to use the Painter's algorithm. I have no good clue as to when a surface is behind or in front of another, though. I've tried numerous methods but they all fail in edge cases, or they fail even in general cases. This is a list of sorting methods I've tried so far: Distance to midpoint of each face Average distance to each vertex of each face Average z value of each vertex Higest z value of vertices of each face and draw those first Lowest z value of vertices of each face and draw those last The problem is that a face might have a closer distance but is still further away. All these methods seem unreliable. Edit: For example, in the following image the surface with the blue point as midpoint is painted over the surface with the red point as midpoint, because the blue point is closer. However, this is because the surface of the red point is larger and the midpoint is further away. The surface with the red point should be painted over the blue one, because it is closer, whilst the midpoint distance says the opposite. What exactly is used in the Painter's algorithm to determine the order in which objects should be drawn?

• Weblogic domain scale up using EM Grid Control 11gR1

  - by dmitry.nefedkin(at)oracle.com

  As you know a weblogic domain consists of set of servers running independently or in a cluster mode, sharing the distributed resources. And in most environments weblogic  cluster consists of multiple managed servers running simultaneously and working together to provide increased scalability and reliability.  These servers can run on the same machine, or be located on different machines.  It's a common task to increase a cluster's capacity by adding new machines to the cluster to host the new server instances.  You can do it by manually installing weblogic binaries to the new host and use pack/unpack commands to add a managed server to this new host.  But with Enterprise Manager Grid Control 11gR1 (EMGC) there is  another way - Fusion Middleware Domain Scale Up  procedure. I'm going to show you how it works.Here is a picture of  my medrec_oradb weblogic domain, what is registered in EMGC. It contains an admin server and a cluster MedRecCluster with  the single managed server MS1. Both admin and managed servers are on the same host oel46-vmware, it's a virtual machine with OEL 4.6 that runs inside our Oracle VM infrastructure.  And here are the application deployments, note that couple of applications are deployed to the cluster.First of all I have to prepare a new machine that will host new managed sever of my cluster. I created new VM with OEL 5.4 using the corresponding Oracle VM template available in Oracle E-Delivery site for Oracle Linux and Oracle VM and named it wls1032. Next step is to install Oracle EM Grid Control 11gR1 Agent to this new host.  You can download it from the OTN page and install it manually,  or you can use Agent Installation Deployment procedure available in EMGC  (Deployments->Agent Installation->Install Agent). Anyway, when you agent is up and running on the new machine, you will see it in EMGC Console in the Targets->Hosts subtab.Now we are ready to scale up our weblogic domain. Click the Deployments tab in Oracle Enterprise Manager Grid Control, and then click Deployment Procedure. Select a Fusion Middleware Domain Scale Up procedure from the list, and click Schedule Deployment. The first page of the FMW Domain Scale Up Wizard is displayed and you can proceed with the deployment process.Select the domain from list, enter the working directory on the admin server host, and also fill the weblogic credentials for the administration server console and the OS credentials for the  admin server host.  Click Next button.  The next step allows you to configure you domain, to add a new manager server to the cluster you should select the cluster in the tree and click Add Server button. Select the newly added server in a tree, choose the target host and  enter the configuration details of your managed server. You can also add new machine and node manager details.  Please note that you cannot change the values in  Domain Location and Fusion Middleware Home fields, so these locations on the target host will be the same as for the admin server host.   Working directory on the target host should have enough free space to store FMW home binaries and domain configuration files.  In my experience the working directories should have at least 3 Gb of free space.  The last thing you should fill is the OS credentials for the target host. The next steps allows you to schedule the execution of the procedure, it is started immediately in my example. The last step is just a review the configuration for the domain scale up. Click Submit to launch the process. You can track the status of the procedure execution by selecting Deployments->Deployment Procedures->Procedure Completion Status in the EMGC Console.As you can see in the picture below, the procedure consists of the many steps, and I'm going to share my experience about the issues that I had at some of the steps. Please keep in mind that you can always continue the execution from the last successfully completed step by clicking Retry button.Check OUI Prerequisites  step may fail if the target host does  not pass prerequisites checks for Weblogic Server installation such as amount of RAM, linux packages installed, etc. Create FMW Clone Archive step may fail if you do not have enough free space in the working directory on the administration server host.Transfer cloning archive to targets  step  may fail if the EMGC agents on the admin server host or on target host are not secured.   You should secure the agent by issuing ./emctl secure agent  command from $AGENT_HOME/bin directory and entering the agent registration password.Both Transfer cloning archive to targets and Apply Clone at target hosts steps may fail if you do not have enough free space in the working directory on the target host. The most complicated issue I had on the Run Inventory Collection  step. The step failed and I noticed that the agent on the target server is also failed with the following error in the $AGENT_HOME/sysman/log/emagent.trc  log file:2010-12-28 11:50:34,310 Thread-2838952848 ERROR upload: Failed to upload file A0000008.xml: Fatal Error.Response received: 500|ORA-20603: The timezone of the multiagent target (/Farm_Localhost_MedRec_medrec_oradb/medrec_oradb,weblogic_domain)is not consistent with the timezone (America/Los_Angeles) reported by other agents.2010-12-28 11:50:34,310 Thread-2838952848 ERROR upload: 1 Failure(s) in a row or XML error for A0000008.xml, retcode = -6, we give up2010-12-28 11:50:35,552 Thread-2838952848 WARN  upload: FxferSend: received fatal error in header from repository: https://oel46-vmware:1159/em/uploadFATAL_ERROR::500|ORA-20603: The timezone of the multiagent target (/Farm_Localhost_MedRec_medrec_oradb/medrec_oradb,weblogic_domain)is not consistent with the timezone (America/Los_Angeles) reported by other agents.2010-12-28 11:50:35,552 Thread-2838952848 ERROR upload: number of fatal error exceeds the limit 32010-12-28 11:50:35,552 Thread-2838952848 ERROR upload: agent will shutdown now2010-12-28 11:50:35,552 Thread-2838952848 ERROR : Signalled to Exit with status 55.

Here was the steps:issued system-config-date command on wls1032.imc.fors.ru  and set timezone to "America/Los_Angeles"propagated the changes to the agent bu executing ./emctl resetTZ agent  command from $AGENT_HOME/bin directoryconnected to EMGC repository as sysman and executed the following PL/SQL block:   begin      mgmt_target.set_agent_tzrgn('wls1032.imc.fors.ru:3872','America/Los_Angeles');      commit;   end;After that I had to clear the pending uploads on wls1032.imc.fors.ru:  rm -r $AGENT_HOME/sysman/emd/state/*  rm -r $AGENT_HOME/sysman/emd/collection/*  rm -r $AGENT_HOME/sysman/emd/upload/*  rm $AGENT_HOME/sysman/emd/lastupld.xml  rm $AGENT_HOME/sysman/emd/agntstmp.txt  $AGENT_HOME/bin/emctl start agent  $AGENT_HOME/bin/emctl clearstate agentThe last part of this solution was to resync the agent in EMGC console by clicking Agent Resynchronization button (please leave "Unblock agent on successful completion of agent resynchronization" checkbox checked in the next screen).After that I issued ./emctl upload command from $AGENT_HOME/bin on the wls1032 host,  and my previous error disappeared,  but I catched another one: EMD upload error: Failed to upload file A0000004.xml: HTTP error.Response received: ERROR-400|Data will be rejected for upload from agent 'https://wls1032.imc.fors.ru:3872/emd/main/', max size limit for direct load exceeded [7544731/5242880]So the uploading XML file size was 7 Mb, and the limit on OMS was 5 Mb.  To increase the max file size limit to 20 Mb I had to connect to the OMS host and execute the following commands from $OMS_HOME/bin directory: ./emctl set property -name em.loader.maxDirectLoadFileSz -value 20971520 -module emoms ./emctl stop oms ./emctl start omsAfter that I issued ./emctl upload command from $AGENT_HOME/bin on the wls1032 one more time and it completed successfully.   The agent uploaded the configuration information to the EMGC  repository and I was able to see the results of my weblogic domain scale-up in EMGC Console.DeploymentsSo, now the weblogic cluster contains 2 managed servers located on the different hosts. This powerful feature of the Enterprise Manager Grid Control  is a part of  the WebLogic Server Management Pack Enterprise Edition.

• No endpoint listening at.........

  - by Michael Stephenson

  I was having some very frustrating behaviour on our build server and while I found a number of articles online with similar error messages none of them helped me.  I thought I would just explain this here incase if helps me or anyone else in future.The error message we were getting is:There was no endpoint listening at http://localhostStubs.ExternalApplication/SampleService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more detailsOur scenario is as follows:We have a solution where a WCF service application hosting the WCF routing service is listening to the Windows Azure Service Bus Relay.  We have an acceptance test project in the solution which sends a message to the service bus which is then received by the WCF routing service and routed to SampleService.svc which is hosted in another IIS application on the same box.  A response is flowed back through to the test.  In the tests there are 5 scenarios simulating a successful message, and various error conditions.  On my developer machine it was working absolutely fine every time, and a clean build on my developer machine worked fine.  On the build server however one or more of the tests would fail each time with the above error message.  There didnt seem to be any pattern to which test would fail.The solution was building on a Windows 2008 R2 machine with IIS 7 and AppFabric Server installed with auto-start configured for the IIS Application which would be listening to service bus.After lots of searching online and looking at logs etc it turned out to be a simple solution to just restart the WAS service (Windows Process Activation Service) and the services it advised you to restart with it.  Hope this helps someone else
