More than one Exchange server on a domain @ different locations

Hello, I'm looking for advice, best practices, on setting up a backup exchange server. I currently have one Exchange 2010 server that everyone connects to. We have about 30 users spread out between 8 locations. We have a mix of bandwidth
capabilities. A couple of us have fiber, we have a couple of sites with t1's, and the rest have business class cable or dsl. All the sites are connected by IPsec tunnels. We're all part of a single domain and some of the sites have a local domain controllers.
What I would like to do is add a second exchange server, at a different site, so that if something happens to the primary server like a fire, power loss, comet :) the other server could take it's place and users could get their email without noticing much
of a difference. Or maybe having them both up at the same time and assigning some users to one server and the balance to the other, and if one went down everyone would still be able to use the server that is working. Any idea's?
If it matters I do have Exchange 2013 licenses. I haven't upgraded yet, but it on the to do list.

Hi Profector,
Great information from Ed.
DAG is a great method to configure a DR site for backup.
I find an article on "Database Availability Group Design Examples" for your reference:

HT2480 setting up more than one exchange account for iphone

Does anyone know how to set up more than one exchange account??

What you have is an alias email address to a primary email account.
You cannot create separate email accounts in Mail that share the same user name, password and incoming mail server due to the account and associated mailbox filing structure at the Finder level. When creating an email account in Mail, an account named folder is created at the first level within the Mail folder at Home > Library > Mail named by the user name and incoming mail server for the account which is why you cannot create multiple accounts that share the same user name and incoming mail server.
To add an alias email address to a primary account, go to Mail > Preferences > Accounts and under the Account Information tab for the account preferences at the Email Address field, add the alias email addresses to the email address for the primary account separated by a comma - [email protected], [email protected], etc.
All incoming messages for all email addresses will be deposited in the Inbox mailbox for the primary email account. If you want to separate messages by email address to a user created "On My Mac" location mailbox, you must create the mailboxes first and then create a rule to move messages received by email address.
When composing a message, the alias email addresses will be available via the account pop-up selection window just below the message header.

How to use more than one application server during initial load?

Hi,
we plan to use more than one application server in CRM during initial download in order to increase the number of parallel requests and to decrease the time for the initial load. Is there a way to allocate requests to more than one server? Is is possible via multiple rfc connections for consumer CRM in CRMRFCPAR?
Thanks.

Hi Naresh,
thanks for your answer. It has solved my problem. SMLG is the transaction that I was looking for.
Two more OSS notes that helped me to guide our basis into the right direction:

OSS 1413986 - SMLG: Possibility to select a favorite type for Ext.RFCs
Thanks again.

That means you have 2 instances running an enque process, even tho this is possible i don't think is meant to be in your system... you need to check why?
Check that parameter rdisp/wp_no_enq is not set in one of the application servers.

Need to download JAR files from more than ONE HTTP-server ?

Hello,
We have a need to download JAR files for an application, from more than ONE HTTP-server, i.e. any specified HTTP-server in an extremely secure network.
Does a solution exist for this requirement ? Is it possible to design a solution our selfes for this problem ?
Best Regards
Peter

We have a need to download JAR files for an
application, from more than ONE
HTTP-server, That can be done using the extension element
from within the resources element of the main JNLP.
http://java.sun.com/j2se/1.5.0/docs/guide/javaws/developersguide/syntax.html#resources
The extension element should refer to another JNLP
(on the other site) that refers to the Jars. The jar files
in any such (foreign) JNLP need to be signed, and the
JNLP files should declare itself as a <component-desc>.
For any level of detail on using extensions/components,
download the spec. mentioned in the second paragraph
of that section linked above. Unfortunately I can find no
web browsable form of the information.
Here is an example though..
http://www.javasaver.com/testjs/jws/04/glclock.jnlp
This (sandboxed) screenaver demo comes off my
javasaver site. It refers to the JOGL API via an
extension element in the JNLP, that points directly
to the JOGL site. You might notice the security
warning that is produced mentions..
Name: JOGL
Publisher: sun microsystems, inc
Source: https://jogl.dev.java.net
..i.e. any specified HTTP-server in an
extremely secure network. I do not know about an extremely secure network,
but if it is OK to launch a normal JNLP for an
application with a 'main()' from the server, I guess
it should be OK to launch extensions off it - you
might need to set up some tests.

More than one ATP Server

Hello guys and gals,
Is it possible to define more than one ATP server for one system?
Like setting rdisp/atp_server = host1,host2
Thanks,
Martin.

Allright, here's the story.
We're running ECC6.0 on AIX, ABAP Stack only.
We are clustered using AIX's HACMP.
We have four LPARs (Logical Partitions, or machines)
Two are clustered and two are standalone supplemental application servers.
Among the two that are clustered, one node is running Oracle (not RAC) and replicated enqueue (ERS), and the other node is running Central Services Instance for ABAP (ASCS) and a primary applicative instance (formerly CI).
The two nodes are mutually redundant.
The CI is actually our ATP server.
If one of the nodes fails, obviously the a take-over occurs on the other node. However, not to overload the node that's taking over the other one, the ASCS instance is restarted but NOT the CI.
The ASCS being the enqueue and message server, the system can run perfectly without the "CI" running as long as at least one supplemental app. server is running.
BUT! This will NOT ensure that the ATP is redundant.
I'm thinking of adding a third instance on the "CI" HACMP node exclusively used for ATP. So on that CI node, there will be ASCS, CI and ATP. Three different instances.
HACMP would be configured to provide redundancy for ASCS and ATP and still not for CI. This would ensure that ATP is always there and respect the rule of not overloading the HACMP node that'll be taking over.
This raises many other questions, like: what work processes do I need for ATP? Can it be a dialog-only instance? Of course it will not placed in any logon-groups...

More than one Integration Server

What would be the business requirement to have more than one integration server (HUB) in same environment.
Lets say DXI100 is used as HUB between 10 other business systems. What would be the business requirement to create another HUB in the same development environment?

Ashish,
>>When I try to create WEBAS ABAP TS, I can see ADD NEW LOGON GROUP on the right side....
Where do you see this? I dont see any option like that.
>>When I try to create a WEBAS ABAP BS,
It Asks for Business System Role as: Application System or Integration Server...what is this?
For all your R/3 and SAP products like SRM, CRM you have to select Application Server. You will create a Business system for XI server. It will be configured as Integration Server.
>>we also have to mention the related integration server, can we have more than one IS in XI???
We can have more than one XI server in your land scape(One for dev, one for QA and one for Prod). All these can have a single SLD and hence you find this option. But you have only one IS in one XI server.

Can RoboHelp projects be part of more than one RH server project group?

Hi. I'm wondering if a RH project can be made part of 2 or more project groups. I'm interested in having the content of a project appear in more than one "search domain" (RHS virtual Web site -- I've forgotten the term for this.)
Thanks!
-Kurt

Regardless of whether the project is published to a different area / context, you can duplicate the existing Single Source Layout changing the publish properties as required. This would save you time and reduce the scope for publishing to the wrong location.

Can I install photoshop cs5 on more than one computer, if "owned" by a different user?

I want to install my recently purchased photoshop cs5 on my macbook, as well as my imac. The only thing I worry about is that the macbook is in my name and the imac is technically in my dad's name, even though he only uses it to surf the web. The only reason he even bought the imac as opposed to anything else is so that I'd have a great place to edit photos. I really need it to be on both, will this work? Anyone have experience with this?

This is what I was able to dig out
May I use the software on more than one computer at a time?
The activation process supports installation on two machines. The Adobe product license agreement allows the primary user to install the product on a primary computer and also on a home or laptop computer for his or her use, provided that the two copies are not used simultaneously. While the activation process supports installing and activating Adobe software on two machines, the usage of the product on the second computer is restricted to the user who licensed the software. Allowing others to use a second copy of the software violates the product license agreement.

I want more than one site, all with personal domain names

I have a dot mac account and I created a personal website using iweb (www.personalname.com) and now I would like to make a site for my business using iweb (www.businessname.com). Is that even possible? I've followed directions from other people. i know that I need to go into iweb and under file click new site and choose the templates and so on. But once I do all of that, I click publish and a box comes up and says this new site will now be published under your www.personalname.com.
Am I missing something, or do I have to buy a completely new dot mac account for my business? Someone please help and walk me through this.
Thanks a bunch!

As Wyodor suggested have your domain name provider activate domain name forwarding for the second site. You'll need to open that site in your browser and get the actual URL to give the provider for forwarding.
To make it easier to edit and publish individual sites I use iWebSites to manage multiple sites.. It lets me create multiple sites and multiple domain files.
If you have multiple sites in one domain file here's the workflow I used to split them into individual site files with iWebSites. Be sure to make a backup copy of your original Domain.sites files before starting the splitting process.
This lets me edit several sites and only republish the one I want.
If you expect a lot of traffic to your business site you might want to consider having it hosted on a commercial hosting site that will not be bogged down with all of the bells and whistles that the MobileMe servers are in order to provide all of the special features. A commercial server will be faster and more reliable. Depending on where you purchase your business domain name you can host it on their servers.

More than one Database Server on one host

Hallo,
We want to implement two systems on one host with MaxDb as database. I know it is possible to run 2 DB-Instances on one host, is it possible to upgrade or patch one instance without inflicting the other one with this changes?
For example:
I have the development and test system on one host with two database instances running. is it possible to only upgrade the Database Instance of the Development System without upgrading the test instance.
I know it is possible in Oracle but is this also possible for MaxDB?
I hope you can give me an answer.
best regards,
Patrick Volny

Hello Patrick,
1) "If I understand you correctly, I am able to patch each Instance separately but because the instances share the same kernel to upgrade an Database I have to upgrade all instances?"
    Answer: You can update the database instance separately.
                   As the independent database software is shared between database instances, located in /sapdb/programs by default installation and it's downward compatible
                  ==>
                  you could upgrade only one database instance & run the another database instance with the higher version of the independent database software.
   Warning: Please follow the recommended structure of the database software installation & install the dependent on the version of the database system software once for each database instance.
                  By default it's installed in /sapdb/<SID>/db
    Example : On the local server ::
dbmcli db_enum
OK
SC1#C:\sapdb\sc1\db                        #7.6.04.11#fast#running
SC1#C:\sapdb\sc1\db                        #7.6.04.11#slow#offline
LVC750#c:\sapdb\lvc750\db                     #7.6.00.21#fast#offline
LVC750#c:\sapdb\lvc750\db                     #7.6.00.21#slow#offline
xinstinfo SC1
IndepData           : C:\sapdb\data
IndepPrograms       : C:\sapdb\programs
InstallationPath    : C:\sapdb\sc1\db
Kernelversion       : KERNEL    7.6.04   BUILD 011-123-181-372
Rundirectory        : c:\sapdb\data\wrk\SC1
xinstinfo LVC750
IndepData           : C:\sapdb\data
IndepPrograms       : C:\sapdb\programs
InstallationPath    : c:\sapdb\lvc750\db
Kernelversion       : KERNEL    7.6.00   BUILD 021-123-117-795
Rundirectory        : c:\sapdb\data\wrk\LVC750
In my case, I have installed two database instances of the versions 7.6.00   BUILD 021 and 7.6.04   BUILD 011 on one server,
Independent database software is installed in C:\sapdb\programs and each database instance has own InstallationPath.
And you could run also 'sdbregview -l' to get the short list of all installed database packages, pay attention to the "Database Kernel" package
for the dependent database software installation path/version.
2) "I also read that to patch an instance you have to stop an x server service. But this service is necessary for the communication between applications and the database. so if i patch an instance the second one can't work properly?"
The X Server is needed for the client to establish the connection to a database instance located on a remote computer. As you know the X Server is the communication server for the database system. The X Server listens out for connection requests from clients such as database applications and database tools.
As I already wrote you, that the independent database software is downward compatible & you should not have the problems with the communication to the Test database on the TEST system.
I case you would like to know more details about the database version software, if there are any known problems, please update with additional information::
      What are the current versions of the DEV and Test databases?
      Did you install the application servers on the database server or not?
      To what version of the database are you going to update the DEV database instance?
       What is the version/SP of the SAP basis on the TEST system?
        What is the version/patch of the SAP kernel on the TEST system?
3) The installation distinguishes between different software directories, as you already know.
For example, the following directories:
       - <independent_program_path>
          SAP Standard:/sapdb/programs
          Run the command 'dbmcli -s dbm_getpath IndepProgPath' or 'xinstinfo' to get the current value on your system.
          !!!! This directory contains instance- or version-independent software that works downwardly-compatible.
       - <independent_data_path>
          SAP Standard:/sapdb/data
           Run the command 'dbmcli -s dbm_getpath IndepDataPath' or 'xinstinfo' to get the current value on your system.
       - <independent_data_path>/config
          SAP Standard:/sapdb/data/config
       - <InstallationPath>
SAP standard: /sapdb/<SID>/db
       - <run_directory>
SAP standard: /sapdb/data/wrk/SID
If you are SAP customer,
please see the SAP notes::
             1020175     FAQ: MaxDB installation, upgrade or applying a patch
             820824     FAQ: MaxDB / SAP liveCache technology

Is there a way to have more than one SMTP server on iPod Mail?

The thread at this link http://tinyurl.com/5op2jn seems to indicate it's possible but there are no details provided.
Can anyone help? Does anyone know if this could be a feature included in a future iPod Touch update?

Then there's something wrong because when I added a second account with a different SMTP server, it changed the first account's SMTP server to be the same as the second one. If I then change the first one to be correct it then changes the second one to be the same as the first.
