Failover using SLM2008 and 2 linux servers

I am wondering if LACP 802.3ad can work in this scenario where I have a single SLM2008 switch and 2 linux servers (not 2 nics in a single server)... is it possible to configure the switch to send packets to the alternate server if the primary one no longer responds?

lacp is a method to control the bundling of several physical ports together to form a single logical channel. it may act as failover when link fails between 2 devices but they should have multiple links. if there is only one link between the 2 devices then it will not act as failover. on your case, i believed that it is not possible. lacp works by sending frames down all the link that have protocol enabled. if lacp is enabled on both server, both server will receive the frames from the switch.

How to create and use file share in linux

Hi,
I just started trying out Azure, I have 2 linux ubuntu instances. I would like to create a File share to use as a type of NAS and mount it on both of the instances.
How can I go about doing that? Is there a tutorial?
thanks
Ricardo

Hi,
We can use Azure File services to do this, for more information, please have a look at this article:
http://blogs.msdn.com/b/windowsazurestorage/archive/2014/05/12/introducing-microsoft-azure-file-service.aspx. The Azure File service exposes file shares using the standard SMB 2.1 protocol. Applications running in Azure can now easily share files between
VMs using standard and familiar file system APIs like ReadFile and WriteFile.

I am using jboss 4.2, java5.0 and Fedora Linux Enterprise Version 4.0 with

Hi,
I am using jboss 4.2, java5.0 and Fedora Linux Enterprise Version 4.0 with kernel 2.6 and NPTL 2.3.4
I am using open source network chart generation API provided by geosoft ( http://geosoft.no/graphics/). This API generates chart into swing window.
I wrote the code to change this swing window into web browser compatible jpeg image. I used thread to generate the image. It is working fine, for one user and no other processes running on the application.
ISSUE:- When more than 5 users hit the application at the same time, some images get generated, some donot, there is no fixed trend to this image generation process.
I analyzed CPU timing, it is using 100% CPU and after the images are generated / not generated, the CU usage goes down to zero.
When I used the same code with Linux 9.0 (kernel 2.4, NPTL � 0.6), rest remain the same, it is working perfectly fine with more than 10 users, with all images being generated within 30 secs
Can somebody help me out to figure out whether it is a kernel issue / NPTL issue? Does it have something to do with thread processing?
Code for network chart generation :-
NetworkGenerator ntw=new NetworkGenerator();
BufferedImage img;
ntw.setVectRootNodes(vectRootNodes);
ntw.setHashChildNodeNames(hashNodeData);

Configure CRS2008 to using AD and Kerberos with Java application servers.

Hi All,
I have configure CRS2008 to using AD and Kerberos with Java application servers. Domain Controller is installed on W2K3 Server. In addition, CRS2008 is installed on another W2k3 Server.
I have create service account in domain controller: CMSACC
I have create two user account: CRuser1 and CRuser2
I have create domain group: CRSGroup
After I had run the setspn in domain controller,I got the message at below:
Registered ServicePrincipalNames for CN=CMSACC, OU=TEST, DC=BD, DC=com:
    BOBJCentralMS/BDMGTSRV.BD.com
CMC Setting:
AD Administration Name: BD\administrator
Default AD Domain: BD.com
Add AD Group(Domain\Group): secWinAD:CN=CRSGroup,OU=TEST,D=BD,DC=com
Service principal name:BOBJCentralMS/CMSACCatBD.com
I have create a WINNT folder in root directory.Moreover and save bcsLognin.conf and Krb5.ini at here.
bscLogin.conf:
com.businessobjects.security.jgss.initiate {
com.sun.security.auth.module.Krb5LoginModule required;
krb5.ini:

dns_lookup_kdc = true
dns_lookup_realm = true
[realms]
forwardable = true
BD.com = {
default_domain = BD.com
kdc = BDMGTSRV.BD.com
I have tested the Kerberos,using kinit CMSACCatBD.com password, and got error message at below:

My problem is failed to logon CMC and infoview and got error message at below:
Account Information Not Recognized: Active Directory Authentication failed to log you on. Please contact your system administrator to make sure you are a member of a valid mapped group and try again. If you are not a member of the default domain, enter your user name as UserNameatDNS_DomainName, and then try again.
Actually, I am sucessful to logon Business View manager with CRuser1. However, I fail to logon CMC and infoview and got the above error. Have you any suggestion to solve this problem?
Ken.

if you can logon with client tools then that should be an indication that the service account running the CMS IS working! Good news.
So the problem is likely with the java portion (krb5/bsclogin or java options)
If the files are in c:\winnt\ (if not copy them there) and perform c:\program files\business objects\javasdk\bin\kinit username
then enter and password/enter again
Probably get the same message. To note in your krb5.ini all domain info must be in CAPS (the .com appears to be in lower case)
kinit works with just the krb5.ini, java SDK and AD (removing BO config and the service account from the picture). Once that works if your java options are specified properly you should be able to login to CMC/infoview.
also 1 last point. Add udp_preference_limit = 1 to the krb5 lib defaults section
libdefaults
default_realm = BD.com
dns_lookup_kdc = true
dns_lookup_realm = true
udp_preference_limit = 1

Tim

I have used eclipse to create an executable jar. This is run on the console with commands like
#java -jar myJarFile.jar
Am using linux(OpenSUSE)
How can I create an executable file in search a way that the use just clicks on the icon and the system launches?>There are at least two basic ways you can head.
1) Add a manifest file to the Jar that specifies the main class. The end user can 'double click' it to launch the app.
2) Deploy the Jar using webstart, which can install desktop and menu item shortcuts for a program (plus adding splash screens, automatic update..) while installing it.

Can i use vps's for linux edge server's???

so am i out of luck for using vps's?
any help would be great thanks

yeah no that doesn't work but get this...
when i publish to windows edge server the signal gets sent to origin vps then to viewers...
but if i make windows origin and vps edge server is does not work dont understand why this is happening

Subject: can i use vps's for linux edge server's???
I agree load balancing part but load balancing should be done in context of subscribing and not in terms of publishing. You can do failover in context of publishing using Multi-point publish.
If you publish directly to origin and then introduce edge servers for subscribing do you still face issue.
I mean if you set up your linux VPS as edge and then subscriber goes through that edge - say like rtmp://linuxedge/?rtmp://origin/live - does this work?
Can you try that out and let me know.

Parameters of NFS in Solaris 10 and Oracle Linux 6 with ZFS Storage 7420 in cluster without database

Hello,
I have ZFS 7420 in cluster and OS Solaris 10 and Oracle Linux 6 without DB and I need mount share NFS in this OS and I do not know which parameters are the best for this.
Wich are the best parameters to mount share NFS in Solaris 10 or Oracle Linux 6?
Thanks
Best regards.

Hi Pascal,
My question is because when We mount share NFS in some servers for example Exadata Database Machine or Super Cluster for best performance we need mount this shares with specific parameters, for example.
Exadata
192.168.36.200:/export/dbname/backup1 /zfssa/dbname/backup1 nfs rw,bg,hard,nointr,rsize=131072,wsize=1048576,tcp,nfsvers=3,timeo=600 0 0
Super Cluster
sscsn1-stor:/export/ssc-shares/share1 - /export/share1 nfs - yes rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp,vers=3
Now,
My network is 10GBE
What happen with normal servers only with OS (Solaris and Linux)?
Which parameters I need use for best performance?
or are not necessary specific parameters.
Thanks.
Best regards.

IP failover, load balancing and notification...

Pretend I have the following setup/hardware:
Two intel xserves running 10.4. One is for http traffic the other https. The http server contains a static html website while the other server has a large dynamic database driven website and all of its pages require ssl encryption. I'll refer to the first as server 1 and server 2 for the other.
Now I want to implement a solution for providing high availability and performance.
If I wanted IP failover I would need two additional servers, one for the first webserver and the second for the other. Likewise if I wanted to address load balancing I would also need two additional servers, one for server 1 the other for server 2. Now my questions:
1) It seems implementing load balancing as described on page 32 of Apples High Availability pdf that this would also provide high availability like IP failover does. If two additional servers were purchased to provide high availability via a load balancing strategy would there be any need to implement IP failover? Does load balancing provide the same benefits as IP failover when talking about high availability? When if ever would one need to implement both strategies?
2) Can you somehow provide IP failover with only one server as the backup using the setup above (a third server to provide IP failover for both servers 1 and 2)? Assume the third server has all the data of both server 1 and server 2.
3) Is it possible to have Server Admin or Raid admin notify you of a problem via calling your cell phone or sending you a text message as opposed to only email, maybe via a third party solution? I think (not 100% sure) APC offers this when the power left in their batteries reaches a certain level.
Thanks.
G5 xserve Mac OS X (10.4.8)

1) There's generally no need to implement IP Failover at the server level if you're already using a separate load balancing solution. The load balancer should be able to take care of dealing with a failed server.
2) Good question - it's not clear whether IPFailover will failover for one machine or more than one.
3) Most cellphone providers offer an email-to-SMS gateway, allowing you to send an email to an email address that's forwarded to your phone as a text message. Check your cellphone provider for details on what that email address might be (e.g. Cingular uses <phonenumber>@cingularme.com, Verizon uses <phonenumber>@msg.myvzw.com, etc.

Site list update not working with TED and Zenworks for Servers

Subject: Site list update not working with TED and Zenworks for Servers ,
all on Linux
Description: We have an exiting environment with 6 ZfS Servers and now we
brought up a new Server for another location. I configured all same as on
the other Server and the new one created all NAL-Apps at the new location.
But in the Application Site list on the golden App is this Application
missing. So I clicked on the Link up site list on the Distribution Screen
in C1. On ApplicationSite list the App from the new location is missing.
So I removed all and added the new from the new location and now i see all
in the application site list.When I install an app on the client on the
new location NAL is connecting alway th the same (wrong location-server
and i get an msi error 1612 or id=53272 with path=\Wrong serverpath to
file.
I looked on the other tab on C1 at the golden app an I see the backlinks
are going to all other servers without the new one. Software installation
on other locations are ok

Andreas,
I forgot to mention that you can also set the loging level on the Distributor and the Subscriber to 6. to do this at the Zenworks Server Management prompt type "setconsolelevel 6" if you want to capture this to the log file ted.log then use "setfilelevel 6"
Next delete the Distribution from the Subscriber and then re-push the channel.
What we are looking for here in the log is the creation of the object and the linking information about the gold object. it should look like this (not the failure part ;-))) )
In this excerpt you will see the entry

This should be were the link is to
You can check this both ways in the Golden App and in the Distributed Application.

Specifying Partner Failover in odbc.ini for Linux ODBC driver for SQL Server

Hi,
We are trying to specify the partner failover when making connections via Linux ODBC driver for SQL Server. Do you know a way to specify partner failover in the DSN entry in odbc.ini?
We are using Linux ODBC driver for SQL Server and unixODBC DriverManager.
Our DSN is:
[MyDSN]
Driver=ODBC Driver 11 for SQL Server
Description=MyDSN
Server=MySERVER,<port>
I also tried to use the following connection string in Python (via pyodbc) bypassing the DSN and connecting using the server name.
cnxn = pyodbc.connect("Server=server1,<port>;UID=sa;PWD=<pwd>;Driver=ODBC Driver 11 for SQL Server;Failover_Partner=Server2,<port2>;Database=MyDB")
If the standby DB is on server1 connection fails. It doesn't try server2. If the DB is principal on server1 connection succeeds.
Thank you,
Liviu
LLL

Hello,
Did you use ODBC Driver for SQL Server to connect to database that uses database mirroring?
According to
the BOL,it does not list "Failover_Partner" as ODBC Driver for Linux connection string keywords.
But ODBC driver for Linux supports
AlwaysOn Availability Groups or Failover Cluster Instance by specify MultiSubnetFailover=True when connecting to a SQL Server 2012 availability group listener or SQL Server 2012 Failover Cluster Instance.
The following case is about similar issue and it seems that ODBC Driver on Linux does not recognize Failover_Partner in connection string. (Not test myself).You can refer to:

1 NodeManager, 1 Admin Server and 2 Managed Servers

Hi All, I'm new in Weblogic and this is my 1st time to post a question on this forum. Would like ask for help from you all above my setup, I'm not sure whether it will work or not. Please find out the scenario below:
Setup:
1 Machine (RedHat Enterprise Linux 5.5)
1 NodeManager
1 AdminServer (Name: APP)
2 Managed Servers (Name: APPLIVE, APPUAT)
Currently I would like to using one NodeManager to control both Managed Servers under 1 machine. When I configure my APP Admin Server and two Managed Servers, i would like to nmEnroll both Managed Servers under one NodeManager but it will overwrite my enroll entries if i enroll 2nd Managed Server.
Is it possible to configure NodeManager to accept both Managed Servers entries? Thanks. :)
Edited by: user13602952 on Jan 2, 2011 9:54 PM

Hi Hong,
Following are the few things which you help you understand about NodeManager and nmEnroll
- First of all a Node Manager process is not associated with a specific WebLogic domain but with a machine
- When you run a nmEnroll then you just give "domainDir" and "nmHome" which would then gets the file called "*nm_password.properties*" which contains the encrypted username and password that is used for server authentication and "*SerializedSystemIni.dat*" file.
Example:
nmEnroll([domainDir], [nmHome])
- With above files it also updates the nodemanager.domains file with the domain information which was mentioned in the above command.
Thus when you run the nmEnroll command it would get all the details which it needs to start any managed servers in the same Machine, hence you do not need to run the same commend for each managed servers in the same Machine.
For more information have a look at the below links:
