Changing hostname on Callmanager 6.1 and generate new SSL

I'm looking to change the hostname of our Callmanager because of a change in the naming convention for all our servers.
Is it as easy as it seems or are there any precautions I need to be aware of?
My thoughts were to just Change hostname under Cisco Unified CM Configuration for both PUB and SUB
Since I use mostly IP address for most of my configuration, are there anything else I need to be concerned about?
Also, how do I generate a new SSL cert based on this change so admins and users won't get a certificate mismatch prompt?
Thanks!

Premiere project opened - closed sequences and generating new peak files

Hey guys,
I'm working on a big project, which resides on our Drobo. I have been sorting clips and working in sequences for the last couple days now. All media was loaded fine, and peak files were generated.
When I went to open the project this morning, all of the sequences I had been working on (accept for one) had been closed, instead of opening up like how I left them. Further, Premiere is now generating new audio peak files for the project, which is taking forever. Finally, it took 25 minutes to load all of the clips (about 800 or so). They finally finished loading, but I can't start working until the peak files are finished. All in all, i've been at work for 1 hour and still can't work.
Basically, why didn't Premiere open the project as I left it last night? Closed sequences, slow load time, generating new peak files?
I'm working with footage from RED, Sony FS700, GH4, and GoPro.
My system:
Creative Cloud
Premiere Pro 8.0.1
Windows 7 (64 bit)
Intel 3770k
Quadro k4000
16 gb ram
256 gb SSD (System)

Can I change two devices of my Id and assign new id's and still access the same cloud.

After ISO8 my sons iPad rings when I receive a call. I have two 5c's and an iPad under one apple id. Can I assign a new id to my wife's phone and my son's iPad and then all of use the same cloud under the new update? Will my wife lose her contacts? Im thinking what I need to do is start both devices from scratch and assign new id's with different emails and then add them to family sharing. Am I correct here, I just want to verify before attempting so I do not lose anything or create unnecessary backlash in my direction. Thank you for any assistance

If your goal is to stop your son's iPad from ringing when you receive a call, all you need to do is go to Settings>FaceTime on his iPad and turn "iPhone Cellular Calls" off.

1. Parse the document into a DOM.
2. Modify the nodes which you said you wanted modified.
3. Serialize the DOM to a new document.
4. Repeat steps 2 and 3 as required.

Generate new version of doc on each status or change in DIR

how system can auto generate new veriosn of DIR on every change in DIR. for example i change the status of DIR ,system should generate new veriosn.

Hi,
I thinkt that this could be achieved by using BADI DOCUMENT_MAIN01 with the method BEFORE_SAVE. Here you should be able to check if the new data matches the already stored data and if there are differences you can trigger the creation of a new version.

Hi David,
Check this document.
How to Modify Public Network Information including VIP in Oracle Clusterware [ID 276434.1]
In that Document..
Changing public hostname
Public hostname is recorded in OCR, it is entered during installation phase. It can not be modified after the installation. >The only way to modify public hostname is by deleting the node, then add the node back with a new hostname, or >reinstall the clusterwar
Changing public IP only without changing interface, subnet or netmask
If the change is only public IP address and the new ones are still in the same subnet, nothing needs to be done on >clusterware layer, all changes need to be done at OS layer to reflect the change.
1. Shutdown Oracle Clusterware stack
2. Modify the IP address at network layer, DNS and /etc/hosts file to reflect the change
3. Restart Oracle Clusterware stack
Above change can be done in rolling fashion, eg: one node at a time.

Saved Tiffs will not open in CS2 and generate a "Could not complete your request because of a program error".

this was supplied by Ann Shelbourne.
Saved Tiffs will not open in CS2 and generate a "Could not complete your request because of a program error".
These files will often open in Photoshop 7.0.1 or in CS1 but not in CS2.
The trouble may be caused by bad dates in the EXIF data and can originate from an incorrectly-programmed digital camera; or from a scan that was created after after Jan1 of this year (because of a known bug in some scanner software).
If someone runs into the "Could not complete your request because of a program error" problem, and does not have CS1, try opening the Tiff in TextEdit.
The EXIF data is right at the top. Check the EXIF data for bad creation dates and change any incorrect ones there.
Save and close; and then the file will probably open in CS2 without a murmur.

What needs to be changed if we change hostname in linux

Dear all,
I have a question and will appreciate for appropriate answer(s).
My machine name was lxcms120.cern.ch and Oracle 10g DB was running fine on it (listener, DB, Enterprise Manager). It is not a production system rather a test system.
Now, i changed its name to docms11.cern.ch
I change hostname in listener.ora & tnsnames.ora and listener started successfully.
I started db from sqlplus and it started without any complaints.
Now, when i tried to start Enterprise Manager (emctl start dbconsole), it didn't and return this error.
OC4J Configuration issue. /localscratch/orahome/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_docms11.cern.ch_oralxcms120 not found.
Now, i know that when the machine name was initially lxcms120, it was /localscratch/orahome/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_lxcms120.cern.ch_oralxcms120
and if i go to that directory, i could see OC4J_DBConsole_lxcms120.cern.ch_oralxcms120 but of course there is no OC4J_DBConsole_docms11.cern.ch_oralxcms120
My dbname instance is oralxcms120 and has nothing to do with hostname.
So, what is the solution to the problem. Moreover, are there any steps to do while changing hostname of the oracle database like in my case which i can follow to make all required changes.
Best regards,
Anjum

You will need to do a little more than just directory rename,
From Oracle document,When the database host name (including the domain name) or the IP address changes, deconfigure and then reconfigure the Database Console with the repository create command. Run the following command:
emca -deconfig dbcontrol db -repos drop
emca -config dbcontrol db -repos create
or
emca -deconfig dbcontrol db
emca -config dbcontrol db -repos recreate

Select from table in group of columns and generate a sequence number

I have to select data from a table in group of columns and generate a sequence for every group resetting the sequence to start from 1 onwards.
For example:
Data:
Col1 Col2 Col3 Col4
A NA KA 2009-08-13
B NA KA 2009-08-13
C NA KA 2009-08-13
A NA KA 2009-08-13
B NA KA 2009-08-13
A NA KA 2009-08-13
Expected output from Select Statement:
Col1 Col2 Col3 Col4 Seq_No
A NA KA 2009-08-13 1
A NA KA 2009-08-13 2
A NA KA 2009-08-13 3
B NA KA 2009-08-13 1
B NA KA 2009-08-13 2
C NA KA 2009-08-13 1
How can this be possible with a SELECT statement? Is it possible to assign seq numbers for a group of columns and reset it when it changes? In the above example, all columns form the key to generate the seq number
I know it can be done using Stored procedures and that is how I am doing it now by introducing a temporary table.
Can anyone help me in this regard? Please let me know if the question is vague to understand!
Thanks,
Nachi

How to repair Open Directory Master after Changing Hostname

Summary:
How to repair Open Directory after Changing your Server's Hostname (see separate post)
Problem:
I had to change our server's hostname from a private hostname (server.name.private) to a public hostname (name.dyndns.org).
Procedure:
1. Precautions:
Since I was anticipating major dramas I tested the change of hostname on a clone ( I used Super Duper, and I very strongly advise everybody to heed this warning because a change of hostname will corrupt your server services, in particular Open Directory)
Second, I exported the network users from Server Admin and copied the archive to the Drop Folder of the server's local account (because the network accounts will be unavailable after demoting the OD Master.)
2. Change hostname and demote OD Master
a) I re-booted the server from the clone
b) I changed the hostname in Server App and I noticed that the Open Directory Password and the Kerberos database were still stuck with the old hostname.
c) I then demoted to a standalone directory (Server Admin) and I tried to promote the server to an OD Master using the Server App (Manage Network Accounts). Server App always returned an error saying I should check my network settings.
3. List of 'fixes'
I tried the following fixes to no avail (which does not mean that you can skip them)
a) I checked the DNS entries, forward and reverse were working fine (sudo checkip -changehostname)
b) Checked with Lookup in Network Utility, all was fine
c) I deleted all system certificates (Keychain) which showed the name of the previous hostname
( N.B. you need not delete email certificate and private/public keys)
d) I tried to assign a new static IP in Networking Preferences (had no visible result)
e) I re-booted from the working drive and I re-paired permissions on the clone; I ran disk repairs.
Despite all this I could not re-create an OD Master.
I then looked for this dubious folder /var/root/Library/Application Support/Certificate Authority.
I could not find this folder when using the Finder's Go To Folder, nor did "Easy Find" see this folder.
I was about to give up when I read the posts on this page and I entered the Terminal commands
sudo rm -R /var/root/Library/Application\ Support/Certificate\ Authority/
I had not much hope when I set about to re-create the OD Master from the Server App.
But lo and behold !!! I did not trust my eyes when Server App claimed that the OD Master had been successfully created. And indeed, Server admin showed a running OD Master, LDAP, Kerberos and Password Server all running again !
Final touch: re-import the user accounts.
Epilogue:
I woud not have been able to fix this issue had not so many others shared their experience and the working solution.
(Refer : https://discussions.apple.com/thread/3219325?start=0&tstart=0 )
Thank you all !
Let's hope that Apple will fix this annoying issue in the next server update.

Twistan

Change hostname/domain in ebs 12.0.6

Hi All,
I have single node installation of EBS R12 (12.0.6) and database version is 10.2,
I want to change hostname and domain name of application and database.
I have found this document (ID 341322.1). i think this document is for EBS 11i ,
may i follow this document on EBS R12 ?
Thank & Regards
Ravi Kumar

Hi Ravi,
Please have a look at the following notes, applicable to r12:
How to change the hostname and/or port of the Database Tier using AutoConfigNote (338003.1 )
How to change the hostname of an Applications Tier using AutoConfig (341322.1 )
You may follow link:
CHANGE HOSTNAME OR IP-Address OR DOMAIN NAME ON APPS-TIER OR DB-TIER in R12
http://applicationsdba.blogspot.com/2011/04/r12-iphost-name-change.html
Additionally, 2nd step would be..
- Run preclone script on DB and Apps Tier
- Change network necessary changes
- Run the post clone script.
Hope this helps!
Best Regards

PXI 4461 simultaneously read and generate

I am using PXI 4461 card, which has 2 inputs and 2 outputs.
I have a sequence, which will be loaded for multi UUT testing at the same time. I am trying to use AI0, AI1 to read the signals, which are generated by UUTs at the same time. One UUT can measure signal at AI0 and other UUT should measure AI1.
I was in impression that it can be possible to measure both AI0 and AI1 at the same time. But it's giving the error, when I try to measure.
I made the attached VI as an reentrant. Please let me know if this is possible.
I would like to know same if this is possible to generate from AO0, AO1 at the same time with different frequencies (1KHz, 10KHz). AO0 should generate signal with 1KHz and AO1 should generated signal with 10KHz. Is this possible?
Thanks,

4461.vi ‏17 KB

LV2010,
Thank you for using the forums!
First off, I ran your VI as is with one AI. I received the following error:
The message is letting you know you have your MIN set higher than your MAX. Basically, your max value is currently set to -10 and your min value is set to 10. Switch those, and you eliminate the error.
In order to read from both ai0 and ai1, you can simply put them both in the control window:
This is called channel expansion.
In order to see the waveforms, I added a Waveform Graph to my front panel and then on the block diagram I wired it to the data output of the DAQmx read.
The DAQmx Read VI will read the channels in the order in which you specify in the Physical Channels terminal.
In terms of generating two outputs from AO0 and AO1 at the same time, that is definitely something you can do! I have attached the final VI, but this is how I did it...
First, I opened the example finder by going to Help >> Find Examples. On the bottom left, I selected the PXI-4461 and marked the box next to where it says "Limit results to hardware". Navigating to Hardware Input and Output >> DAQmx >> Analog Generation >> Voltage, I opened the example "Cont Gen Voltage Wfm-Int Clk-Non Regeneration.vi".
Taking a look, this will allow us to generate one waveform at one frequency. First off, I know I want to output two different waveforms with separate information. I selected the relevant indicators and controls, then pressed Ctrl+C and dragged it over to create a copy. I changed labels and moved stop button to make it more appealing, and changed the waveform information.
Then, I moved to the block diagram. I placed a new Function Generator.vi and moved/wired the controls/indicators I created above to the inputs/outputs of the new function. I changed the error wire to go through the new Function Generator.vi before going into the DAQmx write. Lastly, I connected the sampling information from the first function generator to the new one.
Next, we need to change the write function. It is currently set up to write an along waveform with 1 channel and N samples. We want N channels and N samples. Change the DAQmx write to Analog >> Multiple Channels >> Multiple Samples >> 1D Waveform. By doing so, it creates an broken wire between the output of the one function generator.vi that is still wired to the input of the DAQmx write vi.
The reason for this is that the DAQmx write with N channels and N samples expects an array of waveforms, not a single waveform. I deleted this wire and placed a Build Array (Programming >> Arrays >> Build Array). I dragged it down to expand it to hold two waveforms, one for ao1 and one for ao0.
The order that you wire the two waveforms into the array will determine which waveform is output on which channel. The first waveform in the array will be output first. We will put the first function generator output to the first row of the Build Array function and the second to the bottom row. Then wire the output of the Build Array function into the DAQmx write.
The block diagram now looks like this:
All that is left is left is to specify what channels we want. We will again use channel expansion. Remember, the first waveform we wired into our array will be the first output, and the first in the list of the control will be the channel output first.
The front panel now looks like this:
And we are done! I have attached the final version of this VI as well as the edited version of the VI you posted.
I know this was long, but I hope it was helpful!
Also, here is an article and here is an example from our community forums you may find helpful.
