NW2004s Installation fails in High Availability Environment

We are installing our Production Server
SAP Netweaver 2004s with High Availablility.
AS per the inst guide, we installed the Oracle 10G in Local Disk of both the nodes.
Then Installed the OFS and the SCS Instance successfully.
Then we created the Oracle Fail Safe Group.
After this when we try to install the Database Instance, During the Prerequisites Check, we are getting the message as the
"Oracle Software is not installed. Install Oracle First"
But we have the Oracle installed in the Server into local disk.
Any Ideas?
Thanks & Regards

Hi Benny,
Thanks for the info. We recieved a reply in OSS stating that NW2004s in HA is note tested.
It will only work with NW2004s SR1.
Now we are plannign to go with Distributed System installation without HA because we will not get the NW2004s SR1 DVD.
Where can we get the info about how to Convert the System Landscape from the Distributed System to HA System. Is this possible as part of the migration or as a seperate installation.
Can you please help me in your views on Converting from Distributed Environment to HA Environment.
Thanks & Regards

File Adapter vs BPEL interaction issue on high availability environment

Hi all,
i would really appreciate your help on a matter i'm facing about a composite (SCA) deployed on a clustered environment configured for high availability. To help you better understand the issue i briefly describe what my composite does. Composite's instances are started by means of an Inbound File Adapter which periodically polls a directory in order to check if any file with a well defined naming convention is available. The adapter is not meant to read the file content but only its properties. Furthermore, the adapter automatically makes a backup copy of the file and doesn't delete the file. Properties read by the adapter are provided to a BPEL process which obtains them using the various "jca.file.xyz" properties (configurable in any BPEL receive activity) and stores them in some of its process variables. How the BPEL process uses these properties is irrilevant to the issue i'd like to pose to your attention.
The just described interaction between the File Adapter and the BPEL process has always worked in other non-HA environments. The problem i'm facing is that this interaction stops to work when i deploy the composite in a clustered environment configured for high availability: the File Adapter succeeds to read the file but no BPEL process instance gets started and the composite instance gets stuck (that is, it keeps always running until you don't manually abort it!).
Interesting to say, if I put a Mediator between the File Adapter and the BPEL, the Mediator instance gets started, that is the file's properties read by the adapter are passed to the mediator, but then the composite gets stuck again 'cos even the mediator doesn't seem to be able to initiate the BPEL process instance.
I think the problem lies in the way i configured either the SOA infrastructure for HA or the File Adapter or BPEL process in my composite. To configure the adapter, i followed the instructions given here:
http://docs.oracle.com/cd/E14571_01/integration.1111/e10231/adptr_file.htm#BABCBIAH
but maybe i missed something. Instead, i didn't find anything about BPEL configuration for HA with SOA Suite 11g (all the material i found refers to SOA Suite 10g).
I've also read in some posts that for using the db as a coordinator between the file adapters deployed on the different nodes of the cluster, the db must be a RAC! Is that true or is possible to use even another type of oracle db?
Please, let me know if someone of you has already encountered (and solved :)) a problem like this!
Thanks in advance,
Bye!

Hi,
thanks for your prompt reply. Anyway, i had already read through out that documentation and tried all settings suggested in it without any luck! I'm thinking the problem could be related to the Oracle DB used in the clustered environment, which is not RAC while all documentation i read about high availability configuration always refers to a RAC db. Anyone knows if a RAC Oracle DB is strictly needed for file adapter configuration in HA cluster?
Thanks, bye!

SAP Web Dispatcher in a high availability environment

Hello, guys
We are working in a CRM 7.0 implementation Project. Our system landscape is the following:
   - Two hosts (host1 & host2) on MSCS cluster (Windows 2008) with SQL Server and ASCS in high availability. Additional, this MSCS cluster has a instance of SAP Web Dispatcher.
   - In these two host weu2019ve installed a CI & DI instance, outside of high availability scope
   - Two additional hosts (host3 & host4) with one dialog instance in every host
We have severe problems with communication between SAP Web Dispatcher and ICM components. Our configuration schema is the next:
   - ASCS (MSCS_virtual_hostname):
ms/server_port_0 = PROT=HTTP,PORT=8141
SAPLOCALHOSTFULL = <MSCS_virtual_hostname>.<domain>
   - IC (host1)
icm/server_port_0 = PROT=HTTP,PORT=8040,TIMEOUT=90,PROCTIMEOUT=600
icm/host_name_full = <host1>.<domain>
   - ID1 (host2)

SAPLOCALHOST = <MSCS_virtual_hostname>
ms/http_port = 8141
icm/server_port_0 = PROT=HTTP, PORT=8042,TIMEOUT=30,PROCTIMEOUT=600
wdisp/add_xforwardedfor_header = TRUE
In SAP Web Dispatcher log weu2019ve found the following error messages:
Fri Jan 28 15:45:22 2011
***LOG Q0I=> NiPConnect2: connect (10061: WSAECONNREFUSED: Connection refused)

*** ERROR => Connection request to host: , service: 8044 failed (NIECONN_REFUSED)
SAP Web Dispather is trying to connect to connect with dialog instances through , which itu2019s incorrect (ports 8044, 8045 & 8046 are opened in dialog instances, not in virtual instance). I think it should try with real hostnames (host1, host2, host3 & host4).

Hello Elmar,
If you are instaling the NW4 s on your company's domain and if you have not changed the master password for all the portal users then it might be conflicting with your company's security policy.
Please chjange the master password according to your company;s secirity policy and then re-start the installation?
Or create all the users before and as per the company's policy and then re-start the installatioin.
I hope it helps.
Thanks and Regards

SAP NetWeaver 7.30 High-Availability installation without MSCS

Hi all,
Do we have any option to install SAP NetWeaver 7.30 High-Availability System on the third-party cluster solution, except for MS Cluster Service?
I tried to install the first cluster node without MSCS configuration, however, sapinst.exe checks whether we already set up MSCS on this node, then installer aborted.
I'd like to know the way to disable this checks. (Or, way to mimic the installer as if MSCS cluster configuration was done.)
If unavailable, I have to install MSCS first, and SAP NetWeaver, then also have to uninstall MSCS instead of out cluster software;
It seems to me no sense.
Best regards,

Hi Peter,
Thanks for your quick response.
It is disappointed for me that HA Installation is tightly combined with MSCS.
Do we have a way to migrate from other installation scenario to High-Availability?
For example, once we install ASCS instance as distributed system, then migrate
it for High-Availability usage, leveraged by profile updates and so on?
I'm not sure how High-Availability installation is different from other installation
scenario except for installation path and hostname to be used for connection.
Best regards,

Advice Requested - High Availability WITHOUT Failover Clustering

We're creating an entirely new Hyper-V virtualized environment on Server 2012 R2. My question is: Can we accomplish high availability WITHOUT using failover clustering?
So, I don't really have anything AGAINST failover clustering, and we will happily use it if it's the right solution for us, but to be honest, we really don't want ANYTHING to happen automatically when it comes to failover. Here's what I mean:
In this new environment, we have architected 2 identical, very capable Hyper-V physical hosts, each of which will run several VMs comprising the equivalent of a scaled-back version of our entire environment. In other words, there is at least a domain
controller, multiple web servers, and a (mirrored/HA/AlwaysOn) SQL Server 2012 VM running on each host, along with a few other miscellaneous one-off worker-bee VMs doing things like system monitoring. The SQL Server VM on each host has about 75% of the
physical memory resources dedicated to it (for performance reasons). We need pretty much the full horsepower of both machines up and going at all times under normal conditions.
So now, to high availability. The standard approach is to use failover clustering, but I am concerned that if these hosts are clustered, we'll have the equivalent of just 50% hardware capacity going at all times, with full failover in place of course
(we are using an iSCSI SAN for storage).
BUT, if these hosts are NOT clustered, and one of them is suddenly switched off, experiences some kind of catastrophic failure, or simply needs to be rebooted while applying WSUS patches, the SQL Server HA will fail over (so all databases will remain up
and going on the surviving VM), and the environment would continue functioning at somewhat reduced capacity until the failed host is restarted. With this approach, it seems to me that we would be running at 100% for the most part, and running at 50%
or so only in the event of a major failure, rather than running at 50% ALL the time.
Of course, in the event of a catastrophic failure, I'm also thinking that the one-off worker-bee VMs could be replicated to the alternate host so they could be started on the surviving host if needed during a long-term outage.
So basically, I am very interested in the thoughts of others with experience regarding taking this approach to Hyper-V architecture, as it seems as if failover clustering is almost a given when it comes to best practices and high availability. I guess
I'm looking for validation on my thinking.
So what do you think? What am I missing or forgetting? What will we LOSE if we go with a NON-clustered high-availability environment as I've described it?
Thanks in advance for your thoughts!

Udo -
Yes your responses are very helpful.
Can we use the built-in Server 2012 iSCSI Target Server role to convert the local RAID disks into an iSCSI LUN that the VMs could access? Or can that not run on the same physical box as the Hyper-V host? I guess if the physical box goes down
the LUN would go down anyway, huh? Or can I cluster that role (iSCSI target) as well? If not, do you have any other specific product suggestions I can research, or do I just end up wasting this 12TB of local disk storage?
- Morgan
That's a bad idea. First of all Microsoft iSCSI target is slow (it's non-cached @ server side). So if you really decided to use dedicated hardware for storage (maybe you do have a reason I don't know...) and if you're fine with your storage being a single
point of failure (OK, maybe your RTOs and RPOs are fair enough) then at least use SMB share. SMB at least does cache I/O on both client and server sides and also you can use Storage Spaces as a back end of it (non-clustered) so read "write back flash cache
for cheap". See:
What's new in iSCSI target with Windows Server 2012 R2
http://technet.microsoft.com/en-us/library/dn305893.aspx
Improved optimization to allow disk-level caching
Updated
iSCSI Target Server now sets the disk cache bypass flag on a hosting disk I/O, through Force Unit Access (FUA), only when the issuing initiator explicitly requests it. This change can potentially improve performance.
Previously, iSCSI Target Server would always set the disk cache bypass flag on all I/O’s. System cache bypass functionality remains unchanged in iSCSI Target Server; for instance, the file system cache on the target server is always bypassed.
Yes you can cluster iSCSI target from Microsoft but a) it would be SLOW as there would be only active-passive I/O model (no real use from MPIO between multiple hosts) and b) that would require a shared storage for Windows Cluster. What for? Scenario was
usable with a) there was no virtual FC so guest VM cluster could not use FC LUs and b) there was no shared VHDX so SAS could not be used for guest VM cluster as well. Now both are present so scenario is useless: just export your existing shared storage without
any Microsoft iSCSI target and you'll be happy. For references see:

VM Cluster Storage Options
http://technet.microsoft.com/en-us/library/dn440540.aspx
Storage options
The following tables lists the storage types that you can use to provide shared storage for a guest cluster.
Storage Type
Description
Shared virtual hard disk
New in Windows Server 2012 R2, you can configure multiple virtual machines to connect to and use a single virtual hard disk (.vhdx) file. Each virtual machine can access the virtual hard disk just like servers
would connect to the same LUN in a storage area network (SAN). For more information, see Deploy a Guest Cluster Using a Shared Virtual Hard Disk.
Virtual Fibre Channel
Introduced in Windows Server 2012, virtual Fibre Channel enables you to connect virtual machines to LUNs on a Fibre Channel SAN. For more information, see Hyper-V
Virtual Fibre Channel Overview.
iSCSI
The iSCSI initiator inside a virtual machine enables you to connect over the network to an iSCSI target. For more information, see iSCSI
Target Block Storage Overviewand the blog post Introduction of iSCSI Target in Windows
Server 2012.
Storage requirements depend on the clustered roles that run on the cluster. Most clustered roles use clustered storage, where the storage is available on any cluster node that runs a clustered
role. Examples of clustered storage include Physical Disk resources and Cluster Shared Volumes (CSV). Some roles do not require storage that is managed by the cluster. For example, you can configure Microsoft SQL Server to use availability groups that replicate
the data between nodes. Other clustered roles may use Server Message Block (SMB) shares or Network File System (NFS) shares as data stores that any cluster node can access.
Sure you can use third-party software to replicate 12TB of your storage between just a pair of nodes to create a fully fault-tolerant cluster. See (there's also a free offering):
StarWind VSAN [Virtual SAN] for Hyper-V
http://www.starwindsoftware.com/native-san-for-hyper-v-free-edition
Product is similar to what VMware had just released for ESXi except it's selling for ~2 years so is mature :)
There are other guys doing this say DataCore (more playing for Windows-based FC) and SteelEye (more about geo-cluster & replication). But you may want to give them a try.
Hope this helped a bit :)
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

User experience question for High Availability

Hi Experters,
Not sure whether this is right forum to post this message.
If anybody has already captured user experience for the failover environment, will appreciate their help on this. I will give overview of environment. Using PowerHA for ASCS/SCS failover, ORACLE Data Guard for Database failover.
Trying to capture user experience for the failover environment
if ASCS/SCS fail,
App Server Fail (using F5 Load Balancer which should reroute, unless all app server fail),
Database fail
with following cases:
1. User logged in, NO ACTIVITY. I believe NO IMPACT either ASCS/SCS fail or DB fail or App Server fail.
2. User logged in and run a transaction before failover.
     What will happen in case of ASCS / SCS
     What will happen in case of DB failover
   and what will happen in case of App server fail (NO High Availability, only redundant app servers.      MAX 4 app servers for each component)
3. User logged in and run a transaction during failover.
   What will happen in case of ASCS / SCS
     What will happen in case of DB failover
   and what will happen in case of App server fail (NO High Availability, only redundant app servers.      MAX 4 app servers for each component)
Not sure which one possible or not. Some case thinking system will hang need to refresh. Some case hour glass and then come back once failover complete. and some case session closed completely.
Thanks for your time and god bless the knowledge you have.
Saroj

just try to answer as much as I can (guess)
> 1. User logged in, NO ACTIVITY. I believe NO IMPACT either ASCS/SCS fail or DB fail or App Server fail.
DB failed and SCS failed won't have any impact to enduser, but if app server failed, the user session will lost, user will see a pop up error message at their SAPGUI.
> 2. User logged in and run a transaction before failover.
>      What will happen in case of ASCS / SCS
user wont'be effected during failover if user is doing nothing but idle (replica enqueue is working before failover)
>      What will happen in case of DB failover
App server won't be able to do much thing but it's work processes into reonnecting status. it should resume (reconnect to DB) when failover is compoleted. So user should be able to continue the sessions.
>    and what will happen in case of App server fail (NO High Availability, only redundant app servers.      MAX 4 app servers for each component)
user sessions in failed app server will be lost. However user should be able to logon agan if
1) logon via group, and
2) within the group, there is at least one appl server alive.
> 3. User logged in and run a transaction during failover.
hanging or
>    What will happen in case of ASCS / SCS
if the transaction is using enqueue service, for example, then user will get error message. otherwise, user won't be effected, e.g. if use is just search a list of order. user wont to able to logon via group during the failover.
You also should be pepared for user connected through message server, .e.g. http request dispatching through message server directly , or via web dispatchr. user wont be able to connect during the failover.
>      What will happen in case of DB failover
user will get error message, transaction will be aborted.
>    and what will happen in case of App server fail (NO High Availability, only redundant app servers.      MAX 4 app servers for each component)
very similar case as case 2.

Benefits of high availability

Please let me know the benefits of high availability. Actually i have 2 machines with good spec..
I wana install oracle 10g infrastructure & middle-tier on both machines having o/s windows 2003 server.
where will High availability use and what will be its benefit?
Thanks

Vibe & High Availability

Hello,
I need some advices around the implementation of the Vibe solution in a "High Availability" environment....
Reading the Vibe installation doc, I think we have almost all the info but I have a question around the Tomcat Applications and the File repository.
Do I have to install a shared storage based on ocfs2 for the Tomcat application servers or would be managed by Vibe itself ?
Any info around it will be welcome ....
Of course any feedback or best practices will also be welcome ...
Tx for your help .

Tuxedo and High Availability

Can you provide some information on how Tuxedo can be configured in a high availability
environment. Specifically running Tux 7.1 on AIX 4.3 with HACMP/ES. I am planning
on running with a 'cascading N+1' configuration and have concerns over the ability
of the standby node to take over a failed node succesfully due to config dependancies
on the machine name. Is there a white paper detailing use of Tux in a high availability
environment ?

Found the answers and thought would share it.
1. Can load balancing be achieved in MP setup or is this a high availability configuration?
Both - MP supports load balancing and high availability 2. In an MP setup, can a workstation client continue to work even after the master node gets migrated? If so, can we have both (or all nodes and their WSL) listed in WSNADDR for this to happen
Correct.

High Availability

Hello All
We have to implement add-ins (Java + Abap) WAS installation for XI.
By definition this installation should be High Availability which means that the system should be on the air 24/7.
We have two strong servers for this goal. The ideal configuration for us is that both servers accepts always request but in case of crisis if one of them get down the other one continue from the point that the other one failed. if this configuration isn't possible then other option is that in concurrent time one of the servers will be up and in if it fail the other server raise up and continue from the point that the other failed until the first one recover.
I have a few questions about this implementation:
1.     In which installation architecture should I perform this mission?
2.     Is any restriction to do this task with Netweaver 640 SR1?
3.     Are we need other (except Netweaver) softwares or hardwares for this mission? If yes which?
4.     Any helpful tip or idea will be appreciated.
Thanks in advance

High Availability Test Cases for ECC6.0, PI 7.0, BI 7.0???

Dear All
I am in a pretty difficult situation here. I have to write test cases for the components in the High Availability environment. We are running AIX 5L with HACMP/XD clusters ACTIVE/PASSIVE setting. The following components are in the landscape, ECC6.0, PI 7.0 BI 7.0 cFolders 4.0 Portal 7.0 SLD 2004s and Solman 4.0. I have to write test cases for the above components especially ECC, PI BI and cFolders in the HA environment as to
   1.<b>WHAT WILL BE THE EFFECT ON OTHER COMPONENTS IF ECC</b> <b>FAILOVER and so on for PI and BI</b>,
   2. How do I check the consistency of the system after a failover, since the time for a failover will be anywhere between 3 - 4 mins.
Can anyone pls give me a 5 or 6 checks like
Checking RFC connections
ABAP dumps
Consistency check (txn: SICK)   and so on
In the test cases I have to make sure that after a failover the system is up and ready to perform the activities that it was able to before the Failover......
Will appreciate any suggestions and will definitely reward points for any helpful answers....Thanks in advance.

Hi Shailesh,

As per my understanding there is no need to activate any business function but if you need additional feature of SNC to be used then refer below help link for more details:
http://help.sap.com/saphelp_SNC700_ehp01/helpdata/en/a2/6d67d9b60149cb887acf72ae0b90ac/frameset.htm
In ECC you are going for EPh5 which means no need to activate any additional business function(Normally SNC needs EPh4 only for some the latest feature to be use like in workorder collaboration ManufacturingWorkOrderInformation and ManufacturingWorkOrderProductionProgressNotification XML are used if ECC is with EPh4)

NCS Licensing in High Availability

We are transitioning from a single WCS to NCS, and are looking at high-availability and the costs associated with it. How does the licensing work if you want a NCS high availability environment? If you have a 10,000 device license on your primary, do you have to buy an additional 10,000 license for the secondary as well? Or are they pooled?

A single license is necessary for a given HA cluster - please note the answer in this thread.

Urgent - OBIEE High Availability Deployment - Help Needed

HI All,
I don't have much OBIEE Admin experience, but for a client I have to deploy the OBIEE11g High Availability environment (with cluster,load balancer - http server so on) within a week or so.
I tried to go thru Oracle's guide on deployment,but seems it'd be helpful, if someone who has already done this kind of job - provides a step by step guide with screenshot etc. Otherwise time is too short for this,
Can you please help.
Regards,
Krish

Hi Srini,
I also have similar kind of requirement. I have did all the things mentioned in the above Rittmanmead URL. All the things are working fine, but when Primary BI server is down, then I am not able to log in to the application (it is showing authentication failure). In log file of BI Server it is showing below error
(Error Message From BI Security Service: WSM-06162 The policy referenced by URI "oracle/wss_username_token_service_policy" could not be retrieved as connection to Policy Manager cannot be established at "t3://01HW486222:7001,01HW486222:9704,01HW486222:9704" due to invalid configuration or inactive state.)
where 01HW486222 is our secondary server.
Same error is coming if I am trying to login with Primary server.
Please let me know if anything else need to configure, other than above mention rittmanmead link.
Thanks

Cold backup of High Availability DB 10gR2 in SOLARIS 8 SPARC

Hi
I want to know the procedure of taking Cold backup in Solaris 8 SPARC in
High Availability Environment.
Any reference document will be helpful.
Thanks in advance.
Renuka

That seems to be a contradiction in terms, high availibility and cold backup. When you do a cold backup the database is down and not available. In a primary - standby configuration, you could switch the standby to primary, shutdown the (former) primary and perform a cold backup of it.
