Is Multiple SDM agents in one Host supported?

Hi Experts
I know about the rule of one SDM agent per host. Is it possible to install 2 different SDM agents in one host...
Does SAP supports this? Is there any documentation supporting this.
For Example...
I want my Development systems connected to my both Solution Managers ( Production and Development ). I want to have the possibility to start monitoring from either one of them.
Or, I want an SDM agent pointing to an external service provider to monitor my landscape throught their SolMan, And I want to keep one SDM agent configured to my own Solman Server.
Again
Should/Can I install an additional SDM agent in every system?
Do you have a particular documentation that support this scenario?
Regards and thanks
Henry Lopez

Hi,
first, if you mean SMD Agent, then yes, the diagnostics concept from SAP needs only one diagnostics agent per host.
Big negativ impact on this SAP concept is, that if you implement monitoring with SAP Solution Manager, you have a single point of failure = the SAP Solution Manager itself,
In former days, there was CCMS and primary / secondary target servers possible.
Now with SMD you may have a agent with instance 98 (older versions had 97 as default) which "reacts" to the prod Sol Man and an additional agent with a diffent number which "reacts" to the non-prod Sol Man and so on.
This "single point of failure" in the E2E / SMD concept is for me not acceptable.
Everytime there is a Sol Man downtime, you and your complete "monitoring" will be BLIND.
Sometimes the Java Agent turns from Green to Yellow, then the blindness is for all compontents on that host.
If any alerts (MAI) etc come up, the SolMan down, you will not know / auto-react it until SolMan downtime is over or you restarted the Yellow agent.
That's the reason and solution why the making a SPOF to a "halt/two point of failure" might be better on larger landscapes.

Multiple IQ databases on one host ---- NLS for BW-HANA

Hi,
We are planning to build a Sybase IQ NLS landscape to support BW on HANA landscapes.
We have thought of installing DEV/QA NLS (IQ) on one server and accordingly have created the file systems on the Linux host. My question is whether we have to install sybase IQ 16 SP8 PL27 twice on the server to have two seperate $SYBASE install directories, from which we can source the environmenmt profiles while launching each of these databases.
The FS layout is as follows --- All FS's will be owned by sybase (2 sets of FS will be created with SIDs for DEV and QAS)
/usr/sap/SID/sybase ------------- sybase install dir
/usr/sap/SID/database -------- catalog DB
/usr/sap/SID/main -------------- IQ_SYSTEM_TEMP
/usr/sap/SID/log -- ---- Transaction logs and other system logs ----- Can the transaction log be stored here for Point in Time Recovery?
/usr/sap/SID/messages --------- messages
/usr/sap/SID/html ---------- html query plans
/usr/sap/SID/sapdata1 to /usr/sap/SID/sapdata4 --- for iq db spaces (user db spaces)
/usr/sap/SID/temp/temp1 to /usr/sap/SID/temp/temp4 --- for iqtmp spaces (both the sapdatax and tempx have same sizes)
Question ---- can the base directory /usr/sap/SID/temp become the IQTMP16 and will it access the other file systems (temp1, temp2 and so on) undreneath it or do we have to just create one file system - /usr/sap/SID/temp?
/usr/sap/SID/tmp ----- path for -dt option in the config file to store server dependant files. - I am not sure what this -dt stands for and how different is it from iqtmp FS (usr/sap/SID/temp....)
Question - In the First Guidance guide, this filesystem is mentioned as (IQ for Sort)... Does /usr/sap/SID/temp (iqtmp) and /usr/sap/SID/tmp (.tmp) have same sizes?
Question - Does the /usr/sap/SID/sapdata, /usr/sap/SID/temp and /usr/sap/SID/tmp have same sizes?
We will install DEV under /usr/sap/DEV/sybase and configure it to use the above file systems. Similarly, we will have filesystems for QAS but the install will begin from /usr/sap/QAS/sybase.....
Is it a viable way of installting multiple NLS databases on one server?
Please help....

Multiple Schedule Agents for One Work Repository

Hi
Does anyonem know if it should be possible to have multiple schedule agents running (on different machines, with different names, ports etc.), but all agents use the same master and work repository (defined in odiparams.sh).
I seem to be having a problem with this set up. Only one of the schedules is working. I can add schedules to any of the other agents, but when I go to update scheduling (in TM) and then view the schedule, odi tells me it is unable to retrieve the schule information.
This error is usually caused by either empty schedule, or odiparams.sh connection information not being set correctly. But in my case it must be correct as I can see items in one of the schedules.
Thanks

Hi,
I don't really know if multiple Scheduler agents on the same repositories is possible.
But I just can say that I have the following message too : "unable to retrieve the schedule information".
This message appears each time I try to view the schedule.
I have tried to correct things to avoid this message but it always appears.
At the end all my scheduling works fine so I let it.
Moreover when this message appears if I click ok it loads me the calendar with all the scheduled tasks of the period.
So my question is, what do you see when you click Ok after the Warning message occurs ?
Do yo see the scheduling planning empty ?

How to setup multiple content servers on one host

Hi,
We have setup 2 ECC 6.0 systems on one host ECC DEV and ECC QAS. Windows 2003 Server 64bit
We want to setup 2 standalone Content Servers (MaxDB). One contentserver pointing to ECC DEV and one to ECC QAS. Containing its own content.
Problem is that I was not able to set up 2 content servers on one host because in ISS i could only create one default webservice during installation.
To my opinion it must be possible to setup 2 standalone content servers on one host, question is how?
Can anyone help me how to proceed?
Many Thanks!
Best regards,
Jacco Raymakers.

Hi Jacco
You cannot Configure Two Content Servers on IIS( One Sigle Hardware).
As this Content Server you have configured can be used by both ECC DEV and ECC QAS.
There is no need of two content servers.Same Contentent server can be used by ECC DEV and ECC QAS.
Configure Content Repository and Content category diferrent for ECC DEV and ECC QAS.
I hope I have answered your query.Please let me know if helpfull.

Multiple XI systems on one host - problems

Hi,
We have a problem when installing a second XI system on the same host.
Symptoms are that the J2EE engine of the first running installation does not work anymore, all java related items either hang or do not start.
The abap stack runs as normal. We do get a lot of shortdumps that say that the programs in the RFC connections are not registered. We do not know whether this is cause or result of the problem.
Our Visual administrator does not start anymore as well.
We shut down the newly installed system of course but this does not seem to help.
Anyone have a clue?

Hi Chris,
Im particulary interested in the behaviour of SLD in this kind of infrastructure.
Does your XI environment uses only one or multiple SLD instances?
Do you have access to all your defined business and tech. systems/objects across the XI environment in SLD?
Thanks,
Rob.

Multiple SDM for single WAS instance

Are you talking about SDM servers or SDM clients? There's no need to have multiple SDM servers for one WebAS server.

Using multiple agents through one webgate

How can we use multiple agents through one webgate.when i copy a file OBACESSCLIENT.XML its gets overwritten what should i do.

This is trivial to do - just don't use Finder aliases.
Aliases are Mac OS X-specific and UNIX-based applications like apache don't know how to deal with them.
The solution is to use symbolic links, the original UNIX equivalent of the Mac's aliases.:
<pre class=command>$ cd /Library/WebServer/Documents
$ ln -s /Volumes/User1Drive user1
$ ln -s /Volumes/User2Drive user2
...</pre>
etc.
This will create a symbolic link from user1 to /Volumes/User1Drive. Now when anyone hits /user1 on your server they'll given the content on /Volume/User1Drive.
There is an alternative solution which doesn't use directory paths, but hostnames. It's possible to configure Apache's virtual hosts so that 'http://user1.server.com/' is based on /Volumes/User1Drive while 'http://user2.server.com/' is based on /Volumes/User2Drive, and so on.
This takes some configuration in DNS to point all the hostnames to the same IP address, but it's another option that can scale without the need of more IP addresses.

Dynamic memory allocation on HP-UX for multiple instances on one host

Hi everyone,
I was wondering what the current possibilities are nowadays on running multiple SAP instances on one very large host with regard to resource sharing. Normally, for each instance, using PHYS_MEMSIZE etc you have to set the memory to a fixed size and then optimize it.
Preferrably we would like the memory to be allocated based upon actual usage. Is that possible at all? on HP-UX? Using third party techniques?
Thank you
Marcel Rabe

Hello Marcel,
As Juan said you may not be able to change the parameters at runtime.
The only parameters that can be dynamically switched are :
ztta/roll_first
ztta/roll_extension
ztta/roll_area
abap/heap_area_dia
abap/heap_area_nondia
abap/heap_area_total
em/stat_log_size_MB
em/stat_log_timeout
These parameters would put a cap on memory allocations, however they wouldn't help increase the total addressable memory area.
I would suggest that you consider Adaptive Computing for dynamic use of resources.

Multiple machines with the same host name

Has anyone tried it? Is it supported? We have this policy around here that all db servers are called db2 with different domain names. When I tested it, one host registered with GC properly although without domain name (ie db2 only), but agents on the remaining db2 hosts keep dying and never show up in GC. I'm gonna play with it some more, just wanted to ask if anyone has heard of such problem ...
Thanks,
Julius

Actually, if you see the emd.properties file in the $AGENT_HOME/sysman/config directory, you should be able to specify fully qualified host name (e.g. db2.domainname) in the agent url.
If the agent has secure communication setup with OMS, then you will have to re-secure the agent after changing agent url in emd.properties.
Hope this helps.

How to run multiple CodedUI Ordered Tests over multiple Test Agents for parallel execution using Test Controller

we are using VS 2013, I need to run multiple Coded UI Ordered Tests in parallel on different agents.
My requirement :
Example: I have 40 Coded UI Test scripts in single solution/project. i want to run in different OS environments(example 5 OS ). I have created 5 Ordered tests with the same 40 test cases.
I have one Controller machine and 5 test agent machines. Now I want my tests to be distributed in a way that every agent gets 1 Ordered test to execute.
Machine_C = Controller (Controls Machine_1,2,3,4,5)
Machine_1 = Test Agent 1 (Should execute Ordered Test 1 (ex: OS - WIN 7) )
Machine_2 = Test Agent 2 (Should execute Ordered Test 2 (ex:
OS - WIN 8) )
Machine_3 = Test Agent 3 (Should execute Ordered Test 3
(ex: OS - WIN 2008 server) )
Machine_4 = Test Agent 4 (Should execute Ordered Test 4 (ex:
OS - WIN 2012 server) )
Machine_5 = Test Agent 5 (Should execute Ordered Test 5 (ex:
OS - WIN 2003 server) )
I have changed the “MinimumTestsPerAgent” app setting value
as '1' in controller’s configuration file (QTController.exe.config).
When I run the Ordered tests from the test explorer all Test agent running with each Ordered test and showing the status as running. but with in the 5 Test Agents only 2 Agents executing the test cases remaining all 3 agents not executing the test cases but
status showing as 'running' still for long time (exp: More then 3 hr) after that all so its not responding.
I need to know how I can configure my controller or how I can tell it to execute these tests in parallel on different test agents. This will help me reducing the script execution time.
I am not sure what steps I am missing.
It will be of great help if someone can guide me how this can be achieved.
-- > One more thing Can I Run one Coded UI Ordered Test on One Specific Test Agent?
ex: Need to run ordered Test 1 in Win 7 OS (Test Agent 1) only.
Thanks in Advance.

Hi Divakar,
Thank you for posting in MSDN forum.
As far as I know, we cannot specify coded UI ordered test run on specific test agent. And it is mainly that test controller determine which coded UI ordered test assign to which test agent.
Generally, I know that if we want to run multiple CodedUI Ordered Tests over multiple Test Agents for parallel execution using Test Controller.
We will need to change the MinimumTestsPerAgent property to 1 in the test controller configuration file (QTControllerConfig.exe.config) as you said.
And then we will need to change the bucketSize number of tests/number of machines in the test settings.
For more information about how to set this bucketSize value, please refer the following blog.
http://blogs.msdn.com/b/aseemb/archive/2010/08/11/how-to-run-automated-tests-on-different-machines-in-parallel.aspx
You can refer this Jack's suggestion to run your coded UI ordered test in lab Environment or load test.

12c Console reports two agents on one target, I don't understand why

Greetings,
I have completed the installation and upgrade from 11g to OEM12c Cloud Control using the 2-System method and am in the process of deploying/configuring the 12c agents on numerous hosts. On one particular host after successful deployment/configuration of the 12c agent I bring up the 12c console, choose the target in question (there were metric collection errors but those were resolved, not sure if that is pertinent), drill down and under the hosts tab choose related targets. I see two agents displayed.
One agent, the active one is displayed as <hostname>:3872 and is up. The other is displayed as agent12c1_3_<hostname> and shows as n/a. Drilling down to the <hostname>:3872 shows the metrics and performance information of the agent and all is well. But under the monitored targets it lists the agent12c1_3_<hostname> agent and a database target named <sid>.<domain>oracledatabase_home. Both are listed as n/a.
Drilling down to the agent12c1_3_<hostname> agent shows tabs for products, patchsets and a list of patches which have been applied.
From the setup -> agents dropdown this agent does not appear. This second agent did not appear when the host was viewd using the 11g OEM Console.
I haven't been able to find any information as to the source of this, where the agent came form, what configured it and what will happen if I try and remove it. Has anyone else encountered this situation? Any ideas are greatly appreciated.
Thank you.
Bill Wagman

Hi Bill:
As Rajesh has noted, the new agent has multiple HOMEs for separate components. There is the traditional HOME (core), and instance, sbin and plugin locations. This Oracle note has a great summary: 12c Cloud Control Agent - Details of the Directory Structure and Commonly Used Locations in a 12c Agent Installation [ID 1386113.1]. I used it to set the correct environments as I patch the components.

Multiple iPad sync on one computer fail

I am confused about how to maintain two iPads on one computer. Try it and I get dialog boxes threatening to erase all the content on one iPad. Do I creat multiple libraries? That seems risky in light of the "threat" message in the dialog boxes. Is there a simpler way. Why can't I just plug iPad #1 and iPad #2 into a computer and have iTunes recognize that each one should have a separate library? This seems really silly.

How do I set up backup for multiple iphones (40 ) in one Itune?

We will as soon as IP5 is released transfer all of our users from IP3/4 (40+) and to make that progress smoothly
we want to backupp all IP's on one computer.
Is it possible to backup multible iphones/Ipads in one Itune?
How do I set it up?
/Anders

Some of the "sync cart" solutions will hold anywhere from 10 to 40 devices and sync them all to one host pc.....you can also connect multiple devices to a powered usb hub and all of the connected devices will appear on the left side of iTunes...I think the main challenge would be giving each device a meaningful and unique name so that you could identify it when attempting to restore it...we are looking at the the Ergotron tablet management module, they have a user guide that describes the process for connecting multiple devices through their module to one host pc. You might also look at this solution, which is on the Apple Store.

How do I install multiple KMS keys on one server?

I currently am working at Phelps County Regional Medical Center in Rolla, MO and my question is: How do I install multiple KMS keys onto one server? This is very urgent and I have the KMS activating Windows 7 but, I also need all my Office keys, Windows
8, and Windows 8.1 to be activated via KMS. the current KMS is a Windows Server 2008 R2 server. Please help me out and thank you for your time! :)

you need to apply the following update (http://support.microsoft.com/kb/2885698)to your KMS server so you can license up to Windows 8.1. From there your key for 8.1/2012R2 will license everything
downwards and then you can also install your Office KMS key without issue. If its Office 2013 then you need to download the files here (http://www.microsoft.com/en-us/download/details.aspx?id=35584)

How to FaceTime and iMessage on multiple apple devices with one iTunes account

We recently received iPad 2's for Christmas and was looking for some advice on how to FaceTime and iMessage on multiple apple devices with One iTunes Account (Apple Id). I have created or attached other e-mail addresses to our apple id but do not know how to use them on the new devices. Our home MacBook Pro uses our main apple id for FaceTime. The iPads have been setup with the main apple id w/o being able to use FaceTime and iMessage.
Please Help...
I appreciate the help and support.

P and V-
If you are trying to connect to someone with a different Apple ID, I think all the devices should work, but one at a time.
The problem is when you try to connect between two with the same Apple ID. Once the calling device tries to make the connection, it finds the second device to be "busy". That is where each needs to use a different E-Mail address when setting it up.
On iOS devices, when you press the Home button to exit an App, the App may still be active in the background, even when the device is sleeping. If FaceTime or iMessage is merely being active that way, it may be enough to "tie up" the E-Mail address.
From the Home screen, double click your Home button. You will see a list of recent Apps along the bottom of the screen. Press and hold on one of them until they start to wiggle. You will then see a red minus sign on each. Pressing the minus sign will remove an App from the list, and stop it from working in the background. (Click the Home button to stop the wiggling, and again to hide the recent Apps.)
