• Joining Samba to Active Directory with local user authentication

  - by Ansel Pol

  I apologise that this is somewhat incoherent, but hopefully someone will be able to make enough sense of this to understand what I'm trying to achieve and provide pointers. I have a machine with two network interfaces connected to two different networks (one of which it's providing several other services for, such as DNS), running two separate instances of Samba, one bound to each interface. One of the instances is just a workgroup-style setup using share-level authentication, which is all working fine. The problem is that I'm looking to join the other instance to an MS Active Directory domain (provided by MS Windows Small Business Server 2003) to enable a subset of the domain users to access the shares from Windows machines on the other network. The users who need access from the domain environment have accounts (whose names are all-lowercase versions of their domain usernames) on the machine running Samba, but I'm not sure about how to map the UIDs and everything I've read concerns authenticating accounts on that machine against either AD or another LDAP server. To clarify: I only want the credentials for AD users accessing the non-workgroup Samba instance to be authenticated against AD, not the accounts on the machine running Samba. I hope this is sufficiently clear. EDIT: In addition to being able to access the Samba shares from AD, I do also need to be able to access a share on the domain from the machine running Samba but would still like everything non-Samba-related to authenticate locally.

• OS X can't copy files from Windows Home Server...over wifi.

  - by John Clayton

  I'm a brand spanking new user of OS X, coming from a lifetime of Windows use. I've been setting up my new Macbook Pro and have run into a very unusual problem. Over wifi, I am unable to copy files to or from my Windows Home Server. The problem seems to exist only over wifi, and only to WHS. Here are the details of my setup: 2010 Macbook Pro (Core i7), OS X 10.6.3 Windows Home Server PP3 (virtualized in XenServer 5.5) Windows 7 Ultimate x64 desktop Windows 7 Ultimate x64 in Boot Camp D-Link DIR-655 wireless N router Here is what I've done to narrow down the problem: Files copy fine from WHS to OS X when using gigabit ethernet Files copy fine from desktop to OS X when using gigabit ethernet Files fail to copy from WHS to OS X when using wifi (error -51) Files copy fine from desktop to OS X when using wifi Files copy fine from WHS to Boot Camp when using wifi Files copy fine from desktop to Boot Camp when using wifi From what I can tell, it seems to be some sort of issue between OS X and WHS, but I can't for the life of me see what would be different between shares on WHS and my desktop. They are both connected using smb://ADDRESS (I've tried both by IP and name). I can browse the shares on the WHS, but copying to OS X fails. I originally found the issue while installing VS2010 off an ISO from WHS, mounted to a Windows 7 VM using VMware Fusion. During the installation the VM was unusable - even the clock got behind the host be about 8 minutes. Once I plugged in the ethernet and disabled the wifi things picked up and finished quickly. The Fusion 3.1 RC is the only I think of that I installed that may have messed with the wifi driver. I've also tried resetting the wifi router, and have changed it from being G & N to N-only. Under Boot Camp I get similar speeds as my wife's N laptop. Any ideas? Thanks!

• Samba server NETBIOS name not resolving, WINS support not working

  - by Eric

  When I try to connect to my CentOS 6.2 x86_64 server's samba shares using address \\REPO (NETBIOS name of REPO), it times out and shows an error; if I do so directly via IP, it works fine. Furthermore, my server does not work correctly as a WINS server despite my samba settings being correct for it (see below for details). If I stop the iptables service, things work properly. I'm using this page as a reference for which ports to use: http://www.samba.org/samba/docs/server_security.html Specifically: UDP/137 - used by nmbd UDP/138 - used by nmbd TCP/139 - used by smbd TCP/445 - used by smbd I really really really want to keep the secure iptables design I have below but just fix this particular problem.

• OS X Client & Ubuntu Server - Best way for client to access files on server?

  - by Camsoft

  I've got a local development web server running Ubuntu. I also have an iMac running OS X 10.6 which I use a client and is my development machine. I'm currently have Samba server installed on my Ubuntu server. I have shares setup for all the website directories. I then use my Mac and Coda to edit the files via their shares. This generally works really well but I noticed that my Mac was writing loads of resource fork ._filename files everywhere. I found out the following about the files: These files are created on volumes that don't natively support full HFS file characteristics (e.g. ufs volumes, Windows fileshares, etc). When a Mac file is copied to such a volume, its data fork is stored under the file's regular name, and the additional HFS information (resource fork, type & creator codes, etc) is stored in a second file (in AppleDouble format), with a name that starts with "._". (These files are, of course, invisible as far as OS-X is concerned, but not to other OS's; this can sometimes be annoying...) Does anyone know of a way of sharing files between a Mac client and a Linux server that is most compantable between the two operation systems? Ideally it needs to support the HFS filesystem so that the resource forks are not created and it also needs to support the permissions between server and client.

• Automounting Active Directory home drives on a Linux server on login

  - by Ethan

  I've got a Centos 5.7 box authenticating against Active Directory through PBIS Open (the new LikeWise Open), which works well. Now, I'm trying to get the server to automount the user's AD home directory, located at //ad.server.dom/shares/home directories (Yeah, it's a space in the path. I didn't set this up). Each user has a directory in there with the same name as the user. I've tried to get pam_mount working, but it has a series of issues on RedHat and friends, and I can't seem to get that working. The directory does need to be automounted for the server to perform it's role. My reading on automount seems to suggest that there's no way to get it to do it's thing with authentication, though I'm happy to be proved wrong. I've looked at this resource, but it requires version RedHat (thus CentOS) 6 or higher, and newer packages than I have. I can manually (As root) mount the AD directory using the command mount.cifs "//ad.server.dom/Shares/home directories/testuser" /home/local/AD/testuser/nfs_mount/ -o username=testuser and when I log in as testuser, I can see all of the sample files in the nfs_share directory. Any tips towards the right direction would be highly appreciated. This is going to be on a server at a college, so it needs to be fairly stable, and would lead towards more Linux adoption there.

• Chrome browser completely messing with network?

  - by kiasecto

  I have a bizare problem with Google Chrome on a intel core i5 running windows 7 32bit. Whenever chrome is installed, access to other computers in the home group becomes really slow - such as opening shares. Its becomes really slow to resolve windows names. Something goes hay-wire with the local network - pining local machines which is usually 0mS pings I get random timeouts and random successes. Whenever I try to load a local address inside of chrome (including localhost, 192.168.0.1 etc) - it always says something in the status bar about resolving proxy and times out after about 5 seconds, then seems to work fine. If I go to settings inside of chrome, it just brings up the internet explorer connection settings, where I have not set any proxy settings. One I uninstall chrome, all these problems go away. Network shares and name resolvings work instantly, pings to any machines never have a problem. Localhost and other network IP address work fine in all other browsers. Anyone heard of this problem before and know what it might be? I even tried re-installing winodws 7 and the problem came straight back when chrome was loaded on again.

• Anonymous access to SMB share hosted on Server 2008 R2 Enterprise

  - by bwerks

  Hi all, First off, I have read through this post and a whole slew of non-SF posts which seem to address the same or a similar problem, however I was still unable to fix my problem. I've got three machines in this situation: a domain-joined server that runs Server 2008 R2 Enterprise ("share server") a domain-joined workstation running XP Pro SP3 ("test server") a domain-unjoined test server running Server 2003 R2 SP2 ("workstation") The share server is exposing a share on the network that the test server must access--it's a Source/Symbol Server share for our debugging purposes. I believe visual studio simply accesses the the share with its own credentials in this case, meaning that the share must be accessible anonymously since the test server isn't joined to the domain and there's no opportunity to supply domain authentication. I've attempted a lot of things to avoid the authentication window when accessing the share: I've enabled the Guest account on the share server and given Guest full sharing/NTFS permissions for the share. I've given ANONYMOUS LOGON full sharing/NTFS permissions for the share. I've added my share to “Network Access: Shares that can be accessed anonymously” in LSP. I've disabled “Network access: Restrict anonymous access to Named Pipes and Shares” in LSP. I've enabled “Network access: Let Everyone permissions apply to anonymous users” in LSP. Added ANONYMOUS LOGON to “Access this computer from the network” in LSP. Added the Guest account to “Access this computer from the network” in LSP. Attempted to provision the share using the Share and Storage Management MMC snap-in. Unfortunately when I attempt to access the share from the test server, I still see the prompt and I'm forced to enter "Guest" manually. I also tried this workflow using the local administrator account on a workstation, and the same thing happens both with and without XP Simple File Sharing enabled. Any idea why I'm getting these results, or what I should have done differently?

• winbind failing after a semi-random amount of time

  - by The Digital Ninja

  I have winbind set up to authenticate to our AD for samba shares. This is the third such server, and the only one having any issues. It seems after a random amount of time samba shares will just stop working. Winbind processes seem to be running but restarting them seems to fix the issue for a while. Looking at the logs have been kind of hit an miss and I don't know exactly when it fails. One interesting thing is that it seems to be pulling from another domain controller that it shoudlnt. I censored out the domain name in this example. But isnt there some way to block authentication to a domain? I'm not sure if this is a symptom or a cause of the issue.

• Problems with "Read Only" on a Samba share from Windows machines

  - by fistameeny

  Hi, We have a Ubuntu 10.04 Server that has a bunch of Samba shares on it that Windows workstations connect to. Each Windows workstation has a valid username/password to access the shares, which have restricted access governed by Samba. The problem we are experiencing is that Samba doesn't seem to be able to mimic the Windows way of handling "Read Only" attributes. Say I have two users, UserA and UserB, both a group called Staff - UserA creates a file that is readable/writeable by the group (ie. chmod rwxrwx---). If UserA then sets the "Read Only" flag, this changes the permissions to r-xr-x--- (i.e. no write for anyone). As UserB is in the same group as UserA, they should be able to remove the "Read Only" permission - however, they can't as Samba won't allow it. Is there a way to force Samba to allow users within the same group to remove the "Read Only" from a file not created by them? Edit: The Samba smb.conf is as follows: The share is defined in the smb.conf as: [global] log file = /var/log/samba/log.%m passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . obey pam restrictions = yes map to guest = bad user encrypt passwords = true passwd program = /usr/bin/passwd %u passdb backend = tdbsam dns proxy = no netbios name = ubsrv server string = ubsrv unix password sync = yes os level = 20 syslog = 0 usershare allow guests = yes panic action = /usr/share/samba/panic-action %d max log size = 1000 pam password change = yes workgroup = workgroup [Projects] valid users = @Staff writeable = yes user = @Staff create mode = 0777 path = /srv/samba/Projects directory mode = 0777 store dos attributes = Yes The folder itself looks like this: ls -l /srv/samba/ drwxrwxrwx 2 nobody Staff 4096 2010-11-04 10:09 Projects Thanks in advance, Matt

• SVN, Samba and Symbolic Links. How to get them all to play together?

  - by Camsoft

  I've got a website project under version control that relies on files from an unversioned directory on the same server via Symbolic Links. I'm currently storing the symbolic links in the repository. The idea is that if someone checks out a working copy on to the same server they can edit and test the working copy of the project before committing it back to the repository. When they checkout their working copy it successfully sets up the symlinks so that the entire site works when testing. The users that work on the project are Windows users, so I've set a samba shares on the server and then mapped them to network drives in Windows. People can edit their working copies directly on the server via network shares and then test them in the web browser before committing their changes back to the repository via TortoiseSVN. The Problem The problem I have is that Samba resolves the symlinks as expected but when a user tries to commit their changes back to the repository, TortoiseSVN thinks the linked files are part of the project and tries to commit the target files to the repository and not the symlinks themselves. I tried turning off symlink support in samba which means that the linked files cannot be resolved as I don't really want people to have access to the linked files nor do I want to import the linked files in the repository. The problem with this is that I get Can't stat '\webserver\projects\working\project\symlinked_file.php'. Access is denied Apart from the symlink problem everything else works 100% perfectly. Users can either checkout website projects to their machine and work on them (but can't test) or checkout them out to their space on the dev web server and work on them and fully test. So I don't want to change the workflow process, I just need a solution to the symbolic link issue. Many thanks.

• Execute remote shell commands on windows XP embedded

  - by BartD

  The following situation: We have Windows XP Embedded clients that have all admin shares disabled and only have read-only shares (for security reasons). What we want to do is run remote shell (dos) commands on these machines. At first we looked at PsExec & BeyondExec applications (and all sorts of variants), but all of them rely on having at least an admin$ share, which are disabled on our systems. Telnet is not secure enough, as is RSHD servers. So we looked at the next obvious solution: and SSH server. We also prefer an open-source or freeware solution that is still maintained. I looked at freeSSH server for Windows, but that didn't run stable, I tried installing copSSH, WinSSH & openSSH for Windows, but none of these applications seem to work on Windows XP Embedded. The services can either not be installed or cannot be started. I don't know why. Some kind of dependency that is missing. So are there any other solutions out there? I don't care about having to an agent installation locally of some kind on each system, as long as the size of the software is small enough. Can someone suggest some alternatives to what I've already mentioned? Thank you very much.

• Mounting any Windows share from OS X 10.7.5 suddenly stopped working

  - by user2169619

  I have problem with mounting Windows network shares from my OS X 10.7.5 - it worked but it stopped and nothing helps and nothing in logs. Here what I get when trying to mount it manually: mount -t smbfs //10.0.0.7/d /tmp/test When doing sniffing with tshark - no packet it sent through and I get immediately return from the command: mount_smbfs: server connection failed: Unknown error: -1 Nothing in /var/log/syslog.log and /var/log/kern.log. The Finder does not work either - it throws an error that something is wrong (in czech thus I'm not sending the message here). I just cannot connect to any network shares. In virtual Windows 7 in Parallels Desktop I can connect successfully, but not within the network share (so the Win7 is behind OS X NAT) but only with its own IP address. The Windows server share is on the same network segment connected through switch. Any advice how to debug and what can be wrong? I spent hours to find solution on Google and here but no-one with this kind of problem and I do not know how to further debug it since there is no meaningful log / trace etc. I can ping 10.0.0.7 and I can connect to FTP server on 10.0.0.7 - the Windows machine (XP) has firewall completely turned off. The problem is that with tshark, I'm not seeing any packet sending to 10.0.0.7 so it's not even trying to reach the server.

• Sparc Solaris 2.6 will not boot

  - by joshxdr

  I have a very old Sparc Solaris network that was working fine last week, but after a power outage none of the workstations will boot. The network looks like this: host A: solaris 2.6, shares /export/home to network by NFS host B: solaris 8, runs NIS server. Mounts /export/home/ by NFS. host C: RHEL5, shares /share to network by NFS. Mounts /export/home/ by NFS. I figured that the main problem was host A, since you need the home directories available for the other workstations to boot(?). Host A does not mount anything by NFS as far as I know. However, this workstation will NOT boot. The OBP bootup sequence looks like this: Boot device <blah> configuring network interface le0 Hostname <hostname> check file system <everything ok> check ufs filesystem <everything ok> NIS domainname is <name> starting router discovery starting rpc services: rpcbind keyserv ypbind done setting default interface for multicast: add net 224.0.0.0: gateway <hostname> <HANGS at this point> Is there some kind of debug mode so that I can get more detail as to why the workstation won't boot? Is my network structure inherently susceptible to power outage? Is there a way I can boot up to command line so I can at least turn off the NFS mounting?

• Virtualize SBS 2003 - P2V vs migrating to new VM

  - by jlehtinen

  I need to virtualize a SBS 2003 server in my work environment. I need some tips on what people think is the best way to proceed. Background: The SBS 2003 server is the primary DC for the domain and also hosts FTP, RRAS(VPN), DNS, and file shares. Exchange is NOT used, neither is SQL server. DHCP is done via a firewall appliance. I have added a Server 2003 VM to the domain and promoted it to the DC role. AD/DNS is replicating here correctly. This was mainly done to provide fault-tolerance to the domain, I was not intending to make this VM the primary DC. I've already asked about buying upgraded licensing for Server 2008/2012 but was refused due to cost. Options: I see (at least) two routes I could take to complete this. From what I've read option 2 is the "preferred" method, but there's a few steps where I'm not clear on what to expect. Option 1.) P2V the primary DC Power off primary DC Power off secondary DC (to prevent USN rollback in case P2V has issue) P2V (cold clone) primary DC Boot new PDC VM Allow new hardware to detect Remove old NIC hardware from device manager Assign old IPs to new virtual NICs Reboot PDC VM, confirm connectivity and no major issues Power on secondary DC, confirm replication Option 2.)

• Server 2008 R2 & Domain Trusts - Attempt to Compromise Security

  - by SnAzBaZ

  We have two separate Active Directory domains; EUROPE and US. There is a two way trust between the domains / forests. I have a group of users called "USA Staff" that have access to certain shares on servers in the EUROPE domain and a group called "EUROPE Staff" which have access to shares in the USA domain. Recently the USA PDC was upgraded to Windows Server 2008 R2. Now when I try to access a share on a USA server from a Windows 7 workstation in the EUROPE domain I get the "Please enter your username / password" dialog box appear, with a message at the bottom: "The system has detected a possible attempt to compromise security." When I enter a username / password for a user in the USA domain, I can then access the network resource. Entering credentials for a EUROPE user however does not give me access, even though my NTFS and Share permissions are set to allow that. Windows Server 2003 / Windows Server 2008 did not have this problem, it seems to be unique to R2. I found KB938457 and opened up port 88 on the Server 2008 R2 firewall but it did not make any difference. Any other suggestions as to what to turn off in R2 to get this working again ? Thanks

• Can't run utilities/.exe's that use the network from a [DFS] windows share on Windows 2008 servers. Can this be overcome?

  - by Jim Lawhon

  Under Windows Server 2008 I'm unable to run many utilities that use network resources. This works just fine under Windows Server 2003. For example: \\domain\dfs\tools$\bin\sendmail.exe ... \\domain\dfs\tools$\bin\psexec.exe ... echo %_metric% %_value% %_unixtime% | \\domain\dfs\bin\foo$\nc graphite.domain 2003 -w1 Reproducing and maintaining this folder on a large number of servers/vm's is not desirable. Is there a way to allow Windows Server 2008 to run these tools? If so, can this be enabled via GPO or in a fashion that can be scripted during automated builds? Edit: The commands/tools do work just fine, when run from local drives. Edit2: Wget example: d:\scripts\helpers>z:\bin\wget http://www.google.com SYSTEM_WGETRC = c:/progra~1/wget/etc/wgetrc syswgetrc = z:/etc/wgetrc --2011-04-11 00:32:15-- http://www.google.com/ Resolving www.google.com... failed: Host not found. z:\bin\wget: unable to resolve host address `www.google.com' wget can neither use DNS to resolve the IP nor can it use HTTP if provided an IP directly. Edit3: The problem seems to be tied to DFS/DFS shares. Tools run correctly from other normal windows-server file-shares. They also run correctly when run directly from the file-servers behind the DFS. They only fail when we attempt to run them from the DFS UNC path or mapped drives.

• How to correctly setup home directories and permissions on a mounted partition.

  - by user36505

  I'm setting up a Fedora 12 server. I have a root (/) partition where the boot (/boot) partition is mounted and then a separate partition (/files) for separating home directories and shares away from the other partitions. The filesystem mounts fine and users can be created to have home directories in /files/home/[user] just fine. However, when I log in as one of those users, I get an error saying "Cannot chdir in to /files/home/[user]: permission denied". If I create a user under the default /home using the same process, everything works fine. The same goes for when I try and browse a share in windows; I can see the shares, but cannot access them. The permissions and owners on /files and /files/home are the same as /home. When the user is created, the user directory owner and permissions are also the same. How can I set the /files partition up so that it can be used as a home directory and for samba sharing rather than using the root (/) partition? Thanks.

• Create DFS replica from a NAS drive

  - by Mark

  We have two offices, at two different locations. In one we have a NAS, with some shares. We also have a Domain Controller using Windows 2003 R2. We have setup a second Domain Controller using Windows 2003 R2 to put that in the second office. What we would also like is to replicate the NAS drive onto the second Domain Controller so in the second office they have a local copy, and that their changes are replicated back to the NAS. Is there a way to setup DFS replication to do this? Or will it only work with local folders on each Server? Update 1 Sept Base on the answer below, I think I need to add some clarification. The real issue is that the NAS which hosts the shared folder that we want to replicate is external to both servers. And we have a particular share mapped to say S: . In the replication setup it doesnt seem to accept network shares external to the server to be candidates for replication. I can understand why, I just need confirmation that DFSR will only work with block devices that are local on at least one server. Is this the case?

• BYOD (accessing files) on a domain without joining?

  - by Philip White

  I run a Samba 4 instance at a small private school. This makes a regular Linux server appear as a directory controller. There are two relevant benefits to this: I have a Samba share for people's documents, and I use the Redirected Folders feature to allow any employee to sit down at any PC, log in with their domain credentials, and their My Documents points to network storage. Everyone has a mapped drive (using Group Policy Preferences) to a share specific to their account type. Students can access one share (one share for all students), teachers have another, and office staff have another. However, I would like to allow BYOD (Bring Your Own Device). Some employees are already asking for it with their personal laptops, and I know eventually most everyone will want to. Is there any way to replicate the two features above without having to join PCs to the domain? Joining personal PCs is impractical if only because only professional editions of Windows support this. Ideally, any operating system (including mobile) could access the relevant shares, but of course Windows is key. Offline caching is optional. (I could set up OpenVPN for teachers who want to access their files from home.) The problem with simply giving SSH access to the relevant shares is primarily that Samba 4 relies on ext4 ACLs and ext4 extended attributes to maintain NTFS permissions. Writing files directly to the Linux server would bypass this and would (probably) not be interoperable with Samba4. Right now I am completely flexible. I am even fine with scrapping the whole domain and using some other software for the two features above. How can I allow school employees and students freedom to securely share files without requiring everyone to have specific editions of Windows?

• Infinite sharing system (PHP/MySQLi)

  - by Toine Lille

  I'm working on a discount system for whichever customer shares a product and brings in new customers. Each unique visit = $0.05 off, each new customer = $0.50 off (it's a cheap product so yeah, no big numbers). When a new customer shares the site, the customer initially responsible for the new customer (if any) will get half of the new customer's discount as well. The initial customer would get a fourth for the next level and the new customer half of that, etc, creating a tree or pyramid that way that could be infinite. Initial customer ($1.35 discount: 2 new+3 visits + half of 1 new+2 visits) Visitor ($0) Visitor ($0) New customer ($0.60) Visitor ($0) Visitor ($0) Newer customer ($0) New customer ($0) Visitor ($0) The customers are saved along with their IP addresses (bin2hex(inet_pton)) in a database table (customers) with info like a unique id, e-mail address and first date/time the purchased a product (= time of registration). The shares are saved in a separate table within the same database (sharing). Each unique IP addresses that visits the site creates a new row featuring the IP address (also saved as bin2hex(inet_pton)), the id of the customer who shared it and the date/time of the visit. Sharing goes via URL, featuring a GET element containing the customer's id. Visits and new customers overlap, as visits will always occur before the new customer does. That's fine. The date/times are used just to make it a little more secure (I also use the IP along with cookies to see if people cheat the system). If an IP is already in the sharing or customer tables, it does not count and will not create a new entry. Now the problem is, how to make the infinity happen and apply the different values to it? That's all I'd need to know. It needs to calculate the discount for each customer separately, but also allow for monitoring altogether (though that's just a matter of passing all ID's through it). I figured I'd start (after the database connection) with $stmt = $con->prepare('SELECT ip,datetime FROM sharing WHERE sender=?'); $stmt->bind_param('i',$customerid); $stmt->execute(); $stmt->store_result(); $discount = $discount + ($stmt->num_rows * 0.05); $stmt->bind_result($ip,$timeofsharing); to translate all the visits to $0.05 of discount each. To check for the new customers that came from these visits, I wrote the following: while ($sql->fetch()) { $stmt2 = $con->prepare("SELECT datetime FROM users WHERE ip=?"); $stmt2->bind_param('s',$ip); $stmt2->execute(); $stmt2->store_result(); $stmt2->bind_result($timeofpurchase); Followed by a little more security comparing the datetimes: while ($stmt2->fetch()) { if (strtotime($timeofpurchase) < strtotime($timeofsharing)) { $discount = $discount + $0.50; } But this is just for the initial customer's direct results. If I'd want to check for the next level, I'd basically have to put the exact same check and loop in itself, checking each new customer the initial customer they brought to the site, and then for the next level again to check all of the newer customers, etc, etc. What to do? / Where to go? / What would be the correct practice for this? Thanks!

  The Top 10 most-clicked items shared on the OTN ArchBeat Facebook page for the week of December 2-8, 2012 Configure Oracle SOA JMSAdatper to Work with WLS JMS Topics Another of the four posts published on Dec 4 by the Fusion Middleware A-Team blogger identified as "fip" illlustrates "how to configure the JMS Topic, the JmsAdapter connection factory, as well as the composite so that the JMS Topic messages will be evenly distributed to same composite running off different SOA cluster nodes without causing duplication." Web Service Example - Part 3: Asynchronous Part 3 in this series from the Oracle ADF Mobile blog looks at "firing the web service asynchronously and then filling in the UI when it completes." Denis says, "This can be useful when you have data on the device in a local store and want to show that to the user while the application uses lazy loading from a web service to load more data." Advanced Oracle SOA Suite Oracle Open World 2012 SOA Presentations Oracle SOA & BPM Partner Community blogger Juergen Kress shares a list of 13 SOA presentations delivered or moderated by Oracle SOA Product Management at OOW12 in San Francisco. Oracle WebLogic Server WLS Domain Browser My colleague Jeff Davies, a frequent speaker at OTN Architect Day events and a genuinely nice guy, emailed me last night with this message: "I just came across this app on Google Play. It allows WebLogic administrators to browse WLS 12c domain information. I installed it on my phone and tried it out. Works very fast." I'm an iPhone guy, but I'm perfectly comfortable taking Jeff at his word. The app is called WLS Domain Browser. Follow the link for more info from the Google Play site. Retrieve Performance Data from SOA Infrastructure Database Another of the four blog posts published on Dec 4 by very busy Oracle Fusion Middleware A-Team member "fip," this one offers "examples of some basic SQL queries you can run against the infrastructure database of Oracle SOA Suite 11G to acquire the performance statistics for a given period of time." How to Achieve OC4J RMI Load Balancing "Having returned from a customer who faced challenges with OC4J RMI load balancing, I felt there is still some confusion in the field [about] how OC4J RMI load balancing works," says the Oracle Fusion Middleware A-Team member known only as "fip." "Hence I decide to dust off an old tech note that I wrote a few years back and share it with the general public." From XaaS to Java EE – Which damn cloud is right for me in 2012? Oracle ACE Director Markus Eisele wrestles with a timely technical issue and shares his observations on several of the alternatives. Exalogic 2.0.1 Tea Break Snippets - Creating a ModifyJeOS VirtualBox "One of the main advantages of this is that Templates can be created away from the Exalogic Environment," explains The Old Toxophilist. (BTW: I had to look it up: a toxophilist is one who collects bows and arrows.) ADF Mobile - Implementing Reusable Mobile Architecture "Reusability was always a strong part of ADF," says Oracle ACE Director Andrejus Baranovskis. "The same high reusability level is supported now in ADF Mobile." The objective of this post is "to prove technically that [the] reusable architecture concept works for ADF Mobile." Using BPEL Performance Statistics to Diagnose Performance Bottlenecks Someone had a busy day… This post, one of four published on DeC 4 by a member of the Oracle Fusion Middleware A-Team identified only as "fip," offers details on how to "enable, retrieve and interpret the performance statistics, before the future versions provides a more pleasant user experience."
