NAS/SAN commands to be used in a script

Hi
I have a requirement where in scripts/binaries need to manage the NAS/SAN storage for mirroring or failover issues. Are there any commands for NAS/SAN that can be used as part of scripts or in compiled code?
Regards

Hi Stephen
Thanks for the mail and apologizes for being vague. The below are my requirement details (in brief)
1. Working on solaris 10 OS with Sun StorageTek 5320 NAS/SAN,
2. Do not have any volume manager like Veritas
3. Some of the application directories are defined and stored and mirrored in the SAN/NAS
4. running a real-time system with multiple nodes of which couple of nodes will act as active/standby and the NAS filesystems will be mounted on these.
5. In the event the active fails, standby takes over and continues to read-write the NAS directories as they are mirrored.
6. If the Primary NAS goes kaput, the secondary will take over seamlessly.
What I have is a requirement where in I keep monitoring the health and accessibility of the FS defined in NAS. In the event of a primary NAS failure, I should be able to mount, using commands, the secondary NAS FS seamlessly. That is should umount these and mount those to continue to be able to give unbroken access to the applicaitons. In case the primary NAS is back, need to promote those disks and directories so that they become accessible again for the applications and start mirroring again. To do all this, I need to write a script which will connect to the NAS device is able to run scirpts or such to achieve the above.
Hope I am clear. Else please feel free to shoot back the query here.
Regards

Hello Ramanan,
Report Builder : connect JDBC Query in Report Builder is to through Connection Dialog in JDBC Query Editor. User can use a Sign on parameter (can use, default : P_JDBCPDS or can create new) to connect to JDBC Data Source. Connection once made will be mentioned and will be reused through out Reports Builder.
JDBC PDS allows user to connect one or more same or different kind of databases.
While running report through runtime or Server, user can pass the sign on parameter(connection string) value, like any other user parameter.
Syntax for connection string : <username>/<password>@databaseURL . The syntax of database part of connection string depend on the type of JDBC Driver used to connect to Data Source while designing the JDBC Query. databaseURL refer to the location of the database and its format depend on the JDBCPDS river selected in design time while creating the JDBC Query.
rwrun eg :
rwrun report=jdbc_odbc.rdf destype=file desname=output.html desformat=html P_JDBCPDS=scott/tiger@database
Server eg :
http://server.com:8888/servlet/RWServlet?server=MyReportServer+report=jdbc_odbc.rdf+destype=cache+desformat=html+P_JDBCPDS=scott/tiger@database

Custom splash screen only shows up when command line is used...

Hi,
Everything in my Java web start application works perfectly but, the custom splash screen only shows up when command line is used ("C:\Program Files (x86)\Java\jre7\bin>javaws -verbose http://www.xxx.eu/AcSentVivresCrus/AcSentJnlp/AcSent.jnlp"), if I use the shortcut on the desktop or in the start menu, the Java 7 splash screen shows up (tested under Windows Vista and Seven). Does someone have any clues?
Thanks...

Hi again,
I made some researches :
- The link in the generated shorcuts ("C:\Windows\SysWOW64\javaws.exe -localfile -J-Djnlp.application.href=http://www.xxx.eu/AcSentVivresCrus/AcSentJnlp/AcSent.jnlp "C:\Users\Arnaud\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\46\69c1e9ee-1f252d1a") is not the same as the one I use in the command line ("C:\Program Files (x86)\Java\jre7\bin>javaws -verbose http://www.xxx.eu/AcSentVivresCrus/AcSentJnlp/AcSent.jnlp"). Is there a way in the the JNLP file to tell how to generate shortcuts (not the icon, etc., but command line options)?
- This sample (https://blogs.oracle.com/thejavatutorials/entry/changing_the_java_web_start) displays the splash screen when I click on the the generated shortcuts (I use Windows 7). I have copied the ButtonDemo jar file and the JNLP file on my IIS web server (Windows 2008 Server), this time the splash screen does not show up when I click the generated shortcuts but always shows up when I use the command line. Can someone tell me if it is a trouble with IIS ?
Thanks again...

How are Windows Server Backup and Command Line Tools used in vCSHB installation?

How are Windows Server Backup and Command Line Tools used during the installation of vCSHB? Is it required in all types of deployments (PtoV, VtoV, PtoP)? Is it used to create the files that are put in the file share for the second node to use during vCSHB installation or is it only used during a vCSHB clone operation of a Physical to Physical deployment? Are these tools not used in some deployments?

You need Windows Server Backup installed on source and destination, and during the installation of vCSHB the installer will invoke the wbadmin (Windows Server Backup Utility) and will backup configuration and application data (application data is optimal but can decrease the sync time after installation of secondary node). On the secondary node you will need only run the vCSHB installer and everything will be restored.
Check this blog entry for some more info about some problems in P2P deployment: http://www.vcoportal.de/2013/12/vmware-vcenter-server-heartbeat-restore-on-a-second-node-a-journey/

Which ActiveX command do I use to IMPORT TEST FILES INTO EXCEL?

Happy New Year!
I am trying to write large data files to XL, but they take very long to write. Now I am trying to write text files and then near the end of teh program import them into an Excel file. IS there an ActiveX command I should use for this (invoke node)?
Thank-you!
Ivanka

Yes, you can do it.
1. Write a simple VBA procedure in Excel to import text file (or, you can use the macro recorder in Excel to do it) and very it works properly.
2. Copy the code into a string constant in your Labview code. The code must contains "Sub ... End Sub"
3. while you are sting inside Excel, disable Excel macro security check to make it to setting "low"
3. If you have report generation toolkit, then there are three methods: Excel Import Module, Run Module and Remove module. Wire those in sequence with all the appropriate inputs. I'm sure there are corresponding method in Excel ActiveX but could not remember it.
4. test it and modify it until it works

Basically, it is not well-written from both a LabVIEW and a communications point of view. Unfortunately, I can't elaborate because today is an exrtremely busy day at work. I'm hoping this bump will prompt someone to help you with your problem. If you could also provide us with the programmer's guide or the manual for your equipment, that would be extremely helpful.

Then you changed it in CS6. The normal preset usage for that preset is to Redo an Undo.

Why?   I've seen demonstrations on how to use the feature but mine doesn't work. I checked the updates and I have the current version.
Thanks.      LM

What commands can I use in iChat, like "/me"?

What special commands can I use in iChat?
I know about the command /me
And I know there's a command to roll dice
What are the other commands, or what command will get me a list of commands?

Hi,
I know about slashme ( /me )
For those that don't know it is something you can type in a Text Chat and it wil appear in the middle of a Text chat at the same point Timing and the Joining/Leaving messages.
/me waves will appear as "Ralph Johns waves".
The name that appears for you and your Buddies doing this depends on how you store your name in the Address Book (Real name in iChat) and those of your Buddies. If you only know/store their Screen Name That is what appears.
I don't know about the Dice roll though.
Could do with knowing what that is.
