Extending a clustered filesystem with SVM

Hello all,
I need to increase capacity of a file system under cluster control. I think I am 90% done but am coming unstuck when trying to attach the new disk to an existing concatenation. Unfortunately our Storage Guru left last week, leaving the task to me!
I have performed the following activities:
1. Created the virtual disk on the storage array and mapped it to the correct host group
2. Ran devfsadm -c disk on both nodes. The new disk is visible to both nodes at the OS level.
3. Ran scgdevs to create the cluster device ID's. This was successful and the disk is visible to both nodes of the cluster (confirmed via scdidadm -L)
4. Added the new disk to the existing disk set by running 'metset -s oracle-ds -a /dev/did/rdsk/d15'
At this point I believe I need to create a metadevice for the new disk via metainit and then attach it to the existing concat (d31?) but I am not entirely sure how. I have tried a couple of different variations but cannot get the syntax correct.
Any help would be appreciated!
Our config is as follows:
OS: Solaris 9
SC: 3.2
Storage: IBM DS4700
The SVM config looks like this:
Filesystem size used avail capacity Mounted on
/dev/md/oracle-ds/dsk/d30
98G 82G 15G 85% /u02
# metastat -s oracle-ds d30
oracle-ds/d30: Mirror
Submirror 0: oracle-ds/d31
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 209694720 blocks (99 GB)
oracle-ds/d31: Submirror of oracle-ds/d30
State: Okay
Size: 209694720 blocks (99 GB)
Stripe 0:
Device Start Block Dbase State Reloc Hot Spare
d5s0 0 No Okay No
Device Relocation Information:
Device Reloc Device ID
d5 No
# metastat -s oracle-ds -p
oracle-ds/d30 -m oracle-ds/d31 1
oracle-ds/d31 1 1 /dev/did/rdsk/d5s0
oracle-ds/d20 -m oracle-ds/d21 1
oracle-ds/d21 1 1 /dev/did/rdsk/d6s0
oracle-ds/d10 -m oracle-ds/d11 1
oracle-ds/d11 1 1 /dev/did/rdsk/d7s0

A quick search on google brings up this link:
http://forum.java.sun.com/thread.jspa?threadID=5099632&messageID=9340632
This should work if you add a "-s oracle-ds", so I guess the syntax would be:
# metainit -s oracle-ds d32 1 1 /dev/did/dsk/d15s0
# metattach -s oracle-ds d31 d32
Please note, I haven't tried this as I don't have this set up to hand right now. I think it should work though.
Regards,
Tim

Sun Cluster 3.3 Mirror 2 SAN storages (storagetek) with SVM

Hello all,
I would like to know if you have any best practice for mirroring two storage systems with svm on sun cluster without corrupting/loosing data from the storages.
I currently have enabled the multipath on the fc (stmsboot) after that configure the cluster and created the SVM mirror with the did devices.
I have some issues that i wan to know if there's gonna be any problem.
a) 4 quorum votes. As i have two (2) nodes and 2 storages that i need to know which is up i have 4 votes, so in order the cluster to start needs 3 votes. Is there any solution on this like cldevice combine ?
b) The mirror is on SVM level so when a failover happens the metasets go to the other node. Is there any change to start the mirror from the second SAN insteand of the first and have any kind of corruption? Is there someway to better protect the storage ?
c) The storagetek has option for snapshots, is there a good way of using this feature or not?
d) Is there any problem by failling over global filesystems (global option in mount)? The only thing that may write in this filesystem is the application itself that belongs in the same resource group, so when it will need to fail over it will stop all the proccesses accessing this filesystem and it would be ok to unmount it.
Best regards to all of you,
PiT

Thank you very much for your answers Tim, they are really very helpfull, i only have some comments on them to be fully answered.
a) Its all answered to me. I thing that i will add the vote from only one storage and if the storage goes down, i will tell the customer to check the quorum status and add the second storage as QD. The quorum server is not a bad idea, but if the network is down for some reason i thing that bad thing will happen so i dont wont to relly on that.
b) I think you are clear enough.
c) I thing you are clear enough! (just as i thought this would happen for the snapshots....)
d) Finally, if this filesystem is in a metadisk that is been started from the first node and the second node is proxing to the first node for the metaset disks, is there any change to lock the filesystem/ metaset group and don't be able to take it?
Thanks in advance,
Pit
(I will also look the document you mention, a lot of thanks)

How can I extend my wireless network with the Time Capsule?

I recently bought a Time Capsule and set it up, backed up all my data, etc. It is currently plugged in to my AT&T Uverse wireless router via a LAN CAT5e cable. I am wondering if it is possible to wirelessly extend my preexisting network with the Time Capsule so I can move it somewhere else in my house where it can still pick up the signal but extend it. And if possible, how so? Or does it ALWAYS have to be wired'connected to my router for the internet to work?
Thanks in advance.

I am wondering if it is possible to wirelessly extend my preexisting network with the Time Capsule so I can move it somewhere else in my house where it can still pick up the signal but extend it.
Sorry but no. Extending using only wireless would require that the Time Capsule connect to another Apple router that is producing the wireless network.
Another way of saying the same thing is that you must have two Apple routers to be able to extend the signal wirelessly.

Problem in Blazeds with Jboss Clustering ( Mod_JK with SSL )

Hi,
     We are running our flex application in jboss clustering environment with the help of Apache mod_jk(Apache Web server as front end with mod_ssl enabled). We are using the SecureAMFChannel as we deploy the application in SSL. We use the RemoteObject for communicating with Java.
The Application is running fine when we have only one node of JBoss. But once we add one more node to the cluster the application throws the following exception .
Duplicate HTTP-based FlexSession error: A request for FlexClient 'FDCA49A7-9317-4D8A-881F-9248B1136E7A' arrived over a new FlexSession 'C9C563B8266A03C2207C00796CD7DFF1', but FlexClient is already associated with FlexSession '8A328320F5C530D55E94568996A1B552', therefore it cannot be associated with the new session.
As I am maintaing the session in the server, I need to use the JBoss cluster for session replication. I heard that flex clustering is not needed as we have mod_jk and it will do all the stuff for us.
I checked with simple application without any session data also then too I faced the same problem.
After the very first login, I can see 2 session created simultaneously and destroyed. I checked the application whether it calls twice before the session is created, but it is calling only once.
Also when application connects with server2 and if I down the server2 my flex application throws the error that the server is not found, It is not detecting the other server.But it works once I refresh the browser.
Application Environment Details
JBoss 6
Blaze Ds 4.5
Apache Web server 2.2.21
Mod_JK   1.2.32
Mod_SSL 2.8.31
Thanks,
Suresh T
I enabled the sticky session in Mod_jk .
It is working when the connection is not secure(http) in both apache web server and jboss web server ). But when the connection is https the above problem is happening .

Can't get extended class to work with asbstract class

I am having trouble working an extended class to work with my base abstract class. I keep getting this error message: "Fiction.java:4: invalid method declaration; return type required" public FictionBook()" Can someone give me some advice and or guidance on what I need to do? Thanks.
Here is my abstract class:
import javax.swing.*;
public abstract class Book
     protected String bookTitle;
     protected double bookPrice;
     public abstract double setPrice();
public Book()
          setBookPrice();
public double getBookPrice()
          return bookPrice;
public abstract void setBookPrice();
Here is the extended class that I have:
import javax.swing.*;
public class Fiction extends Book
     public Fiction()
          super();
          setBookPrice();
     public void setBookPrice();
          bookPrice = 24.95;
     public String toString()
          return("Fiction Book Price is $" + bookPrice);
}

Fiction.java:2: Fiction is not abstract and does not override abstract method setPrice() in BookThis one is pretty straightfoward: Book declares an abstract setPrice() method. In effect is promises "every concrete subclass of Book will define an implementation of setPrice()". But your Fiction class does not do this - it does not give an implementation of setPrice() even though as a Book it is required to do so. That is what the compiler is complaining about.
Fiction.java:6: call to super must be first statement in constructorThis one is slightly cryptic. If you use super() it must be as the first line of a constructor. You are using it as the first line of Fiction() so that looks OK - until you realise that Fiction() is not a constructor! That's because you declare it as a method returning void. Remove the "void" and the compiler will recognise it as a constructor and will be happy about your use of super().
Edited by: pbrockway2 on Sep 13, 2008 12:13 PM
Just a general point: it might be worth writing very brief comments for your abstract class to say what the methods are supposed to do. It isn't really clear what setBookPrice() is supposed to do given that it isn't passed any argument. Likewise setPrice(), how does it differ from setBookPrice()? what is the double value that it returns?

Clustering TopLink with 10g

We are trying to use TopLink (version 9.0.4.3) in a cluster of Oracle 10g application servers (9.0.4.0.0) but we are having a number of issues getting it to work. When I add the following into the sessions.xml file I get a number of toplink errors on startup:
<cache-synchronization-manager>

All feedback is appreciated,

There was a recent thread on this issue,
Missing Descriptor in Servlet
Basically TopLink does not get notified of the undeployment of an app, so cannot remove the session from the SessionManager. (unless you are using CMP)
If you can receive notification of the deploy/undeploy you could remove or refresh the session from the session manager.
A simple way to do this would be to keep a static boolean variable in your apps class that accesses the session from the session manager. The first time you access the session refresh it and set the static to true.
To refresh a session from the session manager use the API,
SessionManager.getSession(XMLSessionConfigLoader/XMLLoader xmlLoader, String sessionName, ClassLoader classLoader, boolean shouldLoginSession, boolean shouldRefreshSession)
i.e.
SessionManager.getManager().getSession(new XMLSessionConfigLoader/XMLLoader("sessions.xml/or your file name/path"), "yourSessionName", yourClassLoader, true, true);
Only use this API the first time you access the session from the app.
You can also use the following code to remove a session,
SessionManager.getManager().getSessions().remove("yourSessionName");
I have logged this issue internally, hopefully a better solution will be provided in the 10.1.3 release.

Extend Inventory Management (0IC_C03) with new field MSEG-INSMK

Dear Experts, We are using Business Content InfoCube "Material stocks/movements" (0IC_C03) in Area "Inventory Controlling/Inventory Management" in BW. We are using following Business Content DataSources: Stock Initialization for Inventory Management 2LIS_03_BX Goods Movements From Inventory Management 2LIS_03_BF Revaluations 2LIS_03_UM Everything works fine with delta load till now. Now we have a new requirement so that we have to fill additionally the R/3-Field MSEG-INSMK in existing Inventory Management InfoCube (0IC_C03). The Business Content DataSource (2LIS_03_BX/BF/UM) doesn't provide R/3-Field MSEG-INSMK and I don't find any other Datasource for the R/3-Field MSEG-INSMK ("Document Segment: Material" - Stock Type). How can we extend the InfoCube 0IC_C03 with the R/3-Field MSEG-INSMK? Should I define a new Generic Datasource based on the table MSEG to extract the field INSMK. The table MSEG is very large. What would be Delta-Specific Field for Generic Delta? I would load the data from generic DataSource into a new DSO. And I can read the field MSEG-INSMK per Look-Up from the DSO in the transformation to the InfoCube 0IC_C03. Is this the solution? Many Thanks Moha

2LIS_03_BX cannot be enhanced. There is an SAP note that says enhancing this Datasource is not supported.
2LIS_03_BF can be enhanced though, and the process is just like enhancing any other LO Datasource.
So you can include the new field in the cube, enhance BF and load to the cube. With this, you will be able to report the INSMK field on the goods movements. But as INSMK is not present in BX, you will not be able to report the INSMK field on stock position reports.

Registering the ACFS filesystem with CRS

Grid version:11.2.0.2 on Solaris 10
I want to register the ACFS filesystem with the CRS. Which option should I use ; Option A or Option B ?
Option A.
From
http://www.unbreakablecloud.com/wordpress/2011/02/01/acfs-file-system-setup/
You can add the file system using the following srvctl command:
#srvctl add filesystem -d /dev/asm/fs1-334 -v FS1 -g ACFSDG -m /fs1 -u oracle
Start the file systems
#srvctl start filesystem -d /dev/asm/fs1-334 -n node1 (please sure to change node1 to whatever your nodename)
When the system gets rebooted the file systems will be automatically mounted by Oracle Clusterware.or
Option B.
Example borrowed from oracle-base
http://www.oracle-base.com/articles/11g/acfs-11gr2.php
After , creating the Disk group, Creating the volume and enabling it. The following commands are run
-- creating the ACFS
/sbin/mkfs -t acfs -b 4k /dev/asm/acfsvol3-301 -n "ASMVOL3"
--- mounting the ACFS
$ /sbin/acfsutil registry -f -a /dev/asm/acfsvol3-301 /u01/app/oracle/acfsmounts/data_acfsvol3
Do these commands (option 2) register ACFS filesystem with CRS ?In option A, I am curious why he is running srvctl from root (I can see # sign ) ?
Another related question:
Is there any advantage in having ACFS registered with CRS ?

Omega3 -
Both options result in a mount point that is managed by CRS. I refer to this as a managed mount point.
The difference really comes down to what you want to do with it.
If you want a mount point that you can use on all nodes of the cluster and that you can create dependencies on, then use srvctl.
If you want a mount point that is node-local, then you can use acfsutil registry.
If you don't have either of those situations, then you can use either.
Generally, I recommend using 'srvctl'.
As pointed out, you can easily create the resource using ASMCA.
The advantage of this method is that you can create other resources, such as for user defined programs, and create STOP and START dependencies on the ACFS resource. This will ensure that the ACFS file system is mounted before those programs stop and start.
Also, keep in mind that if you are planning on putting large numbers of ACFS file systems in the registry, you may run into some timing issues. The ACFS registry resource has a finite TIMEOUT value, and may run out of time to look at all the file systems\volumes and ensure that they are operating as expected. This is another case where the single file system resource has an advantage.
In either case, add it and forget about it - it should just work. :)

How to extend an existing network with airport

How Do you extend a wireless network using two airports?

Please check out the following Apple Support article for details on how to extend a wireless network with multiple AirPort base stations.

I'm trying to extend my wifi network with time capsule but it can't find the existing wifi network

I'm trying to extend my wifi network with time capsule but it can't find the existing BT wifi network even though it is there with a good signal strength. The Time Capsule is connected to a Netgear router via ethernet.

You will need to start over on the setup of the Time Capsule as follows:
Disconnect any Ethernet cables that might be connected to the Time Capsule, but leave it powered on
Hold in the reset button on the back of the Time Capsule for 8-10 seconds and release. The reset button is located next to the AC power socket.
Allow a full minute for the Time Capsule to restart to a slow, blinking amber light
Connect the Ethernet cable from a LAN <--> port on the Netgear to the WAN "O" port on the Time Capsule. The Ethernet cable must remain connected at all times.
Click the WiFi icon at the top of the Mac's screen
Look for a setting of New AirPort Base Station
Click on Time Capsule
The example below shows an AirPort Express. You will see Time Capsule on your screen.
That will get the setup wizard going. It will take a minute to analyze the settings, then display a screen that looks like this, except you will see a picture of the Time Capsule
Network Name..........Type in the exact name that the Netgear wireless is using
Base Station.............Type in a name that you want to call the Time Capsule. Use something short and simple. Mine is TC, for example
Password..................Type in the exact password that the Netgear wireless requires
Verify.........................Verify the Password again
Click Next
The setup wizard will configure everything for you automatically. When you see the message of Setup Complete, click Done.
That's it. Now you have one big "extended" network. Technically, this is called a "roaming" network.

Extended search by default with closed SC actived as well??

Hi,
Does anybody know if I can put Extended search by default with show also closed SC actived as well.
Could I put a customer field in first place in the search criteria??
It might be done using screen variant or BADI? or I should modify templates or standard code.
Thanks
