Automatic File System Replication at remote(Disaster) Site

Hi all, I have two site one primary and other one is DR. How to configure file system replication for remote site so that any changes/create/delete being made in file system is automatically updated at DR site servers. At both site solaris version is 11.2
Please suggest.

Hi,
A few recommendations:
1. Use an actual clustering product like Oracle Solaris Cluster:
Oracle Solaris Cluster | Oracle
2. If you required synchronous replication, then review this product:
Sun StorageTek Availability Suite 4.0 Software Product Library Documentation
3. A clustered ZFS storage application provides continuous replication across the production and DR sites.
See page 2 of this doc: http://www.oracle.com/us/products/servers-storage/sun-zfs-storage-family-ds-173238.pdf
4. You can build your own Solaris 11.2 ZFS replication by taking hourly snapshots and sending them over to the DR site.
This is not a fully clustered solution, without any kind of automatic failover. ZFS is not a clustered file system so you can't
access the same data from different systems.
Thanks, Cindy

Distributed File System Replication between servers with different performance

If Distributed File System Replication is set between servers with different performance. What will happen with the performance of the fastest server? Will the performance decrease to match the performance of the
slowest server in the chain? I mean, will the source slow down (processor speed) if the recipients can't keep up?

Hi,
If you mix different performance server for DFS replication, most of improvements on the fastest server are disabled for backwards compatibility and the performance decrease to match the performance of the slowest server.
For more detailed information, please refer to the article below:

Source System Conversion in Remote Process Chain

Hi all!
I' working with BI7 SP12 and facing the following problem:
<b>There is no source system conversion for Remote Process Chains, when transporting Process Chains with Remote Process Chains from DEV to QA.</b>
First the following warning appears:
DEV-Destination of Remote Process Chain does not exist on QA-System.
==> The is correct because the DEV-Destination should have been converted to QA-Destination.
Then the following error appears:
Process Chain with the Remote Process Chain was not succesfully checked.
<b>All source system conversion tables are maintained correctly!</b>
The source system conversion works for example for InfoPackages correctly.
But for Remote Process Chain there is neither source system conversion for the Destination nor for Callback Destination. Both should be converted.
Do I have to do it manually??
Or do I have to create the DEV-Destination in SM59 on the QA-System??
==> We want to avoid this...
Thanks for any ideas...
kj

Please note:
When I create the DEV-Destination in SM59 on the QA-System,
the transport gets no warnings and no errors...
But there is still no conversion of the source systems for the Destination and the Callback Destination of the Remote Process Chain to QA-Destinations...
So, i think:
There is no automatic source system conversion of Remote Process Chains and I have to adjust it manually in the QA-System...

Libraries X File System

Hi all.
In my company we are wondering about the possibility of setting up
Library to read directly the server file system, local or remote.
The thing is that we already have a structures file system, correctly
divided, and we want to use this within Groupwise.
We are running GW 7.0.2 on a NW6.5SP5 box, and the file system that we
want to access through GW windows client is a NW 6.5SP5 too.
POA can access the remote server file system, but it is creating several
folders where it just should read the folders that already exists.
Any workaround on this?
Thanks,

Now Iam trying to access text file which is in remote s/m.
It is developing stub and skeleton classes,when i run it is coming for local
If I want to access remotely the error is coming like this
1
2
3
FileServer exception: null4
java.lang.NullPointerException
at FileClient.main(FileClient.java:18)
Can anybody help me please.

Probably the easiest way in this case is to run the performance trace (System/Utilities/Performance trace). Start transaction MD04, put on the trace in another window, press enter to see the stock/requirements list, then stop the trace and list the results. Then you'll see which tables were accesses with which queries.

Display files/directories of a remote system (RIO) on a host machine (PC)

Hello,
Please assume that we are discussing software built on the standard "Labview FPGA Control on Compact RIO" sample project. The host is a standard PC running LV14 Fall edition, the remote system is an sbRIO-9636 having an SD card and a USB HDD attached. The objective is process control. The process being controlled is not relevant to the question.
This question is about implementing the following functionality: the user operates a host machine running a Labview user interface vi (UI Main.vi) locally on the host machine. Part of this vi must offer the user a built in dialogue (some express vi or another) or custom dialogue (a bespoke vi displayed on demand). The dialogue must display the directories and files of the remote system which runs RT Main.vi and it must allow the user to select a single XML file on the remote system (which contains some generic configuration information). The name of the file will then be passed to the remote system and the remote system will act to open it and populate some configuration variables.
I am sure that a widely used solution exists for this problem but I've not found the right words to type into my favourite search engine yet to produce the result. I propose the following:
1) User clicks a "select config file" button on UI Main.vi
2) The UI Main.vi event loop enqueues a message on the UI Main message queue based on the value change event caused by the button press
3) The UI Main.vi message loop enqueues a separate message on to the "UI Command Stream" network stream
4) The RT Main.vi, RT Loop - UI Commands.vi subvi receives the message from the stream and enqueues it on the RT Main.vi message queue
5) The RT Main.vi message loop performs some functions to read the disk structures, directories and file names from the RT system
6) The file and directory name data in (5) is converted to a variant and is passed along with a suitable message into the RT Writer network stream
7) The UI Main.vi periodically reads the RT Writer network stream (it's in the "monitoring loop") and enqueues the received message (from 6) into the UI message queue
8) The UI Main message queue populated the UI Main front panel with the data
9) The user selects the directory and file they desire and clicks an "ok" button
10) The ok button click causes the event loop of UI main to enqueue a message in UI Main.vi's message queue due to the value change on the ok button
11) The UI Message loop enqueues a message on to the "UI Command Stream" network stream with the selected fully qualified file name of the selected file as the data (stored as variant)
12) The RT Main.vi, RT Loop - UI Commands.vi subvi receives the message from the stream and enqueues it on the RT Main.vi message queue
13) The RT Main.vi message loop opens the XML file and populated the appropriate variables with the configuration options therein.
The user should be able to cancel the dialogue and avoid using a configuration file but I have not delt with that here.
Now for the questions:
1) Is this a logical approach?
2) Are there any suggestions for a better way?
3) Any links to some pre-written code that will allow me to impliment all or part of this with minimum effort (I'm thinking here of the dialogue box bit rather than the network streams and events bit as those structures are extant and have lots of bespoke code already in them)?
Thanks,
James
Solved!
Go to Solution.

Hi Bob,
Thanks for your input. You're right I have used network streams.
I implimented more or less what I said in my original post. It works. My main objective was to keep all the config stuff, and data for the particular target on the target's SDCard. On reflection that did make my life much harder than keeping stuff on the host.
It is more (quite a lot more) involved to keep the config files on the target and send directory info etc. back to the host on demand. If I was to do this again I would probably keep the config files on the host machine and keep them in Dropbox or a Google drive so that if I had more than one host to work from (Work PC, Home PC and Laptop...) I would have all my files with little effort. Still I didn't konw that when I started.
Thanks,
James

Creating File System Repository for a remote system

Hi Experts,
My requirement is that I need to create a KM repository in EP from where I need to upload documents into the BW system. Is File System Repository the right type of repository which I need to create for this purpose?
If yes, then in what format do I have to specify the value of the Root Directory property of the repository? I have a folder /data/docs created in the BW system within which I want to upload documents using this repository. But since this folder is located on the BW system which is a remote system for EP, I am not sure how I have to enter the path to this folder.
Can anyone give me any hints on this?
Warm Regards,
Saurabh

Hello Saurabh,
I don't think an FS repository is what you are looking for in this scenario, you could instead use a BI Repository Manager, for more information see:

10G Database install on Linux 64bit File system Vs. Automatic Storage

Hi,
I'm installing Oracle 10G on a Dell 2950 server with an Intel 64 bit processor. The operating system is Red Hat Linux 4. It has a hardware RAID.
I've downloaded the Install Guide but I have a question about installing.
I'm confused about the File system vs. Automatic Storage management option. I will be installing on the local system, I will not be using a NAS or SAN.
Under Database Storage Options, the guide says that "Oracle recommends that the file system you choose be separate from the file systems used by the operating system or the Oracle software.".
1. Do I need to do that since I'm already using hardware RAID??
2. Which way is recommended / what do most people do: File system or Automatic Storage managment??
3. For Automatic Storage Management I read that I'd have to create an ASM Disk group that can consist of "a multiple disk device such as a RAID storage array or logical volume. However, in most cases disk groups consist of one or more individual physical disks". Do I need to reconfigure my partitions ??
I just need some input on what I should do since this is my first time installing Oracle on Linux.
Thank you.

Besides documentation there's a step-by-step guide :

What is virtual file system in sharepoint, where are the site pages stored?

I came across this paragraph in Inside Microsoft SharePoint 2010; page 126 :-
When SharePoint Foundation provisions the Proposals document library,it creates a folder named Proposals at the root of the site and then it creates a child folder named Forms.
Inside the Forms folder, it creates a set of site pages with names such as DispForm.aspx, EditForm.aspx, AllItems.aspx, and Upload.aspx. The reason that SharePoint Foundation creates site pages inside the Forms folder for each
new list and document library is that these site pages will provide users with the forms they will use to add and manage content.
My question is that:-
1) What us the root of the site means?
2) Are the pages for edit/add/allitems created in filesystem OR in the content database?
3)Suppose we create new sitepages, then where are they stored? In filesystem or in content db?

Hi,
For All above queries the data and site pages are stored in content database
Root folder: A folder created for the document library under the web (sub site) and another folder created as child folder named Forms. Site pages are created in SharePoint content database
SitePages(Add/display/edit): These pages are created in SharePoint content database
Note: The SharePoint will not create any physical aspx page OR folder in the file system while creating document library.
Hope this will help you.
Senthilrajan Kaliyaperumal
But the book mentions that:-
When SharePoint Foundation provisions the Proposals document library,it
creates a folder named Proposals at the root of the site and then it creates a child folder named Forms.
Is
this wrong? Are the folders created in filesystem or content db? If the files are not supposed to go into the filesystem, then why are the folders created?

CAF service: import web services using Remote Location / File System

Hallo Experts
I use the NetWeaver DevStudio 7.1 SP5.
I have a CAF project and in this project I want to import one WebService as external service. I have chosen the option "Remote location/ File System" in the import web service wizard, then I enter the URL in the following step. But at the end of wizard I got the error "WSDL could not be downloaded because Server returned HTTP response code 403 for URL". The web service I've deployed and tested on the server. It runs well. Any Hints?

View remote file system

Hello to all.
I have just implemented a simple client/server application which enables file transfers.
I would like to know if there is a way of implementing a remote file viewer in which i will be able to send requests and download files. My primary concern is to be able to view the remote file system of a server on a client computer. Please note that its a two-way application i.e. part of the software is installed on the client, part of it is on the server.
I have browsed through the forums and concluded that it is not possible to do this using a JFileChooser.
Anyone has any ideas regarding this matter?
Kind Regards
Christophoros

hi JaWarrior, thanks for your reply. I think i've read this solution somewhere else in the forums. The solution was like yours collecting the remote file system and sending it to the client. So if i got this straight i should have the server component sending lets say an array of strings with the files of the current working directory to the client?
Also could you please provide an example on how do i go on and grab the contents of a directory?
Many thanks to all

[warn] mod_bonjour: Cannot read template index file '/System/Library/User Template/English.lproj/Sites/index.html'.

Operating System: Lion 10.7.5
I was getting this warn in the logs
[warn] mod_bonjour: Cannot read template index file '/System/Library/User Template/English.lproj/Sites/index.html'.
and looking to the System directory on;
System/Library/User Template
User Template was locked and onwned by the System.
I went to the terminal and type;
sudo mkdir "/System/Library/User Template/English.lproj/Sites/"
sudo touch "/System/Library/User Template/English.lproj/Sites/index.html"
re-started Apache
The warn went away gracefully

I am adding here that this seems to be a permissions bug since the "User Template" is owned by the system and no one else have access to it. The warn went away temporarily because the permissions still wrong in that directory. I changed the permissions on the User Template directory to read and see what is inside and it loops to the user system structure. Most of the directories in the system structure are locked leaving only the public and sites directory with the correct permissions. Inside of the sites folder have a blank index.html file with read access.
So I am not sure if what I did until now will resolve the warn issue.
What I did was to get info on the User Template directory, authenticate as root and change the permission to the admin to read only. That is harmles since not even the admin can change its content. The warn seems to have gone away for now. However, the point here is to find out if the permissions should be read and write for the admin instead of read only or some other conf. More latter!

Implementing a remote file system to use with JFileChooser

Hi all
What I want to do is create a virtual file system so that I can browse through it with JFileChooser, select a file, and then take the correct action. If anyone has something like this that they can post it'd be much appreciated. Otherwise, does anyone have any advice about creating a navigation tool for traversing a vertual file system?

It appears that some people have indeed created some graphical FTP clients incorporating JFileChooser capabilities. The first entry on the search (and a few others) appear useful.

Hi,
I need some guidance here, please.
I have some questions about replication:
When we do a failover to a Replica, what happened to the connected clients? Assuming that the Replica is located in a remote DR site with a different IP configuration.
Is possible to automate the failover process? Just like happens in a cluster.
What changes do I need to do in order to guarantee that my clients reach my replica? For example, I need to do a failover to my Exchange Server Replica and I need to minimize the downtime. The same applies for a DC or a SharePoint Server
  Thanks in advanced.

Hi efebo,
“The same applies for a DC ”
As for replicating virtualized DC (Personally,  I do not suggest to replicate DC , even though it can be replicate ), please refer to following link:
http://technet.microsoft.com/en-us/library/dn250021.aspx
"In short, Exchange does
not support the Hyper-V Replica feature. Exchange has a long history of supporting virtualisation from
Exchange 2003 onwards. It is fully supported to install Exchange
2007,
2010 or
2013 as a virtual machine on Hyper-V, but using the Hyper-V replica feature is not supported.
For details please refer to following link:
http://blogs.technet.com/b/rmilne/archive/2013/07/29/exchange-and-hyper-v-replica-support.aspx
I assuming that the "Remote DR site" and the primary site both have public IPs .
Based on my knowledge you can not access replica site VM  directly after a disaster , maybe you need to rebuild primary site and replicate VM back .
