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)

   - ID4 (host4)
icm/server_port_0 = PROT=HTTP,PORT=8046,TIMEOUT=90,PROCTIMEOUT=600
icm/host_name_full = <host4>.<domain>
   - SAP Web Dispatcheer (MSCS_virtual_hostname):
SAPGLOBALHOST = <MSCS_virtual_hostname>
SAPLOCALHOSTFULL = <MSCS_virtual_hostname>.<domain>
SAPLOCALHOST = <MSCS_virtual_hostname>
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).

Installing SAP ERP on DB2 with high availability

Hey Gurus,
currently we're installing SAP ERP 6 EHP 6 based on DB2 for unix and windows, this is done using the high availability option on AIX 7.1 and IBM's power HA.
We have the following architecture:
          Node A:
                    1-A host for ASCS, ERS and CI.
                    2-A host for the DB instance.
The same with node B replacing CI with DI.
Please advise on how to proceed with installation.
Also I need a bit of clarification regarding how to share (or export) the file systems between the hosts of the same node so that the CI can and DB can be connected, since as far as I know the DB installation will ask for the profile directory through the installation, while the CI will ask to see the db file systems as well as the db instance.
Thanks in advance

Hi Ahmed,
For your query
Also I need a bit of clarification regarding how to share (or export) the file systems between the hosts of the same node so that the CI can and DB can be connected, since as far as I know the DB installation will ask for the profile directory through the installation, while the CI will ask to see the db file systems as well as the db instance.
Please refer installation guide sections related to file system planning.
Here you can see the file system directory structure as well as information on which filesystems to be shared.
Attached are some screenshot for reference
Hope this helps.

Two SAP Instances in High Availability cluster - SGeSAP - HPUX

Dear All
We want to install 2 SAP instances in single host with DB and CI separately. DB and CI will be on High Availabilty Cluster using SGeSAP for HP - Unix. The database is Oracle 10g.
Does SAP support multiple instance on the same hosts(DB and CI) for HA option.
Kindly inform
Regards
Lakshmi

Yes it is possible to run two SAP systems on same cluster using SGeSAP. Normally If there is only one system on the cluster DB is configured on one node and CI is configured on the second node, with fail over in case of a node failure. In your case if a node fails one node will be running two DB and two CI instances. You have to size the hardware accordingly. Just FYI, SGeSAP is licensed per SAP System.

New transactions for BW in SAP ECC source system

Hi experts,
I need to know if in SAP ECC 6.0 there is someones transactions news or changed for datasources manages.
For example:
For create/Modify generic datasource
Activate LIS* datasources
rsa5 Functionality because the hierarchy has differents name; before the hierarchy began with SAP hierarchy, now is Not connected...
Any information about with ECC 6.0 and integration with BI 7: transactions list and migration I will receive very good.
Thank you very much.
Regards,
Jeysi Ascanio

Basically, the same transactions are used. I don´t see a different treatment until now.

UOO sequencing along with WLS high availability cluster and fault tolerance

Hi WebLogic gurus.
My customer is currently using the following Oracle products to integrate Siebel Order Mgmt to Oracle BRM:
* WebLogic Server 10.3.1
* Oracle OSB 11g
They use path service feature of a WebLogic clustered environment.
They have configured EAI to use the UOO(Unit Of Order) Weblogic 10.3.1 feature to preserve the natural order of subsequent modifications on the same entity.
They are going to apply UOO to a distributed queue for high availability.
They have the following questions:
1) When during the processing of messages having the same UOO, the end point becomes unavailable, and another node is available in order to migrate, there is a chance the UOO messages exist in the failed endpoint.
2) During the migration of the initial endpoint, are these messages persisted?
By persisted we mean that when other messages arrive with the same UOO in the migrated endpoint this migrated resource contains also the messages that existed before the migration?
3) During the migration of endpoints is the client receiving error messages or not?
I've found an entry on the WLS cluster documentation regarding fault tolerance of such solution.
Special Considerations For Targeting a Path Service
When the path service for a cluster is targeted to a migratable target, as a best practice, the path
service and its custom store should be the only users of that migratable target.
When a path service is targeted to a migratable target its provides enhanced storage of message
unit-of-order (UOO) information for JMS distributed destinations, since the UOO information
will be based on the entire migratable target instead of being based only on the server instance
hosting the distributed destinations member.
Do you have any feedback to that?
My customer is worry about loosing UOO sequencing during migration of endpoints !!
best regards & thanks,
Marco

First, if using a distributed queue the Forward Delay attribute controls the number of seconds WebLogic JMS will wait before trying to forward the messages. By default, the value is set to −1, which means that forwarding is disabled. Setting a Forward Delay is incompatible with strictly ordered message processing, including the Unit-of-Order feature.
When using unit-of-order with distributed destinations, you should always send the messages to the distributed destination rather than to one of its members. If you are not careful, sending messages directly to a member destination may result in messages for the same unit-of-order going to more than one member destination and cause you to lose your message ordering.
When unit-of-order messages are processed, they will be processed in strict order. While the current unit-of-order message is being processed by a message consumer, the next message in the unit-of-order will not be delivered unless it is to the same transaction or session. If no message associated with a particular unit-of-order is processing, then a message associated with that unit-of-order may go to any session that’s consuming from the message’s destination. This guarantees that all messages will be processed one at a time and in order, and any rollback or recover will not prevent ordered processing of the messages.
The path service uses a persistent store to save the state of which member destination a particular unit-of-order is currently using. When a Path Service receives the first message for a particular unit-of-order bound for a distributed destination, it uses the normal JMS load balancing heuristics to select which member destination will handle the unit and writes that information into its persistent store. The Path Service ensures that a new UOO, or an old UOO that has no messages currently on any destination, can be enqueued anywhere in the cluster. Adding and removing member destinations will not disrupt any existing unit-of-order because the routing decision is made dynamically and those decisions are persistent.
If the Path Service is unavailable, any requests to create new units-of-order will throw the JMSOrderException until the Path Service is available. Information about existing units-of-order are cached in the connection factory and destination servers so the Path Service availability typically will not prevent existing unit-of-order messages from being sent or processed.
Hope this helps.

Discover System with a database cluster environment?

Hi All
We are thinking of getting the Discovery System and are looking into using the SQL Server 2005 Enterprise addition to allow us to use the Discovery System beyond the 180 day evaluation version of SQL Server that comes with the system.
Does anyone know if the Discover System will work with a database cluster environment or does the database need to be installed on the Discovery System box?
Sorry, Im not a BASIS Administrator or DBA.
Thanks!
Mike Vondran

Thanks Rick,
Just to put our proposed usage of the Discovery System into context, our goal is to use it as a proof of concept/ prototyping system to use some of the features of the NetWeaver environment for various different business cases. We would like to use it for this purpose beyond the 180 day SQL Server evaluation addition constraint that comes with the Discovery System. We have existing SQL Server database clusters that we could leverage and wanted to see if it is possible to use them before purchasing an Enterprise Addition of SQL Server.
We would NOT, and could not, be using it for any Production purposes.
Let me know if this usage/environment makes sense.
Thanks again for your help on this.

2 SCM 4.0 Optimizer instances for one SCM system as high availability?

Hi
Can we install more (i.e. 2) seperate SCM 4.0 Optimizers and connect them both to one SCM Server system?
If yes:
1) Can/will the SCM Server system used both optimizers?
2) If one failes, can/will the SCM server then just use the one still running
Best regards
Tom

Hi Larsen
Since optimizer is just exe.file, you can install several optimizers<engine> (put exe.file into
different location <folder>) and it should not be in same HW. And in the IMG customize you can priolatize Optimizer engine. So system can use several engine depending on the priority (or for some component like CTM, you can specify engine and run CTM in parallel with using different CTM engine for different objects.
And I know 1 company who install 2 CTM engine into 2 servers for high availbility solution (This means active server A has 2 CTM engine/ stand by server B has 2 CTM engine).
To use fail over scenario with several server, I think you need to define following customize in SCM system.
T-CD /SAPAPO/COPT01 (Define directly and engine name)
T-CD /SAPAPO/COPT00 (Check availbility of Server)
<Also RFC definition should be correctly customized in SM59).

PI 7.1 High Availability Cluster issue

Dear All,
in our PI7.1 system, we have High availabilty..........we have 2 app servers APP1 and APP2 .............we have 2 servers CI1 and CI2 for central instance.........we are using virtual host as CI everywhere.......so CI can be CI1 or CI2 at any instance.........
Two days back during night for 10 minutes something strange happened........before this time period and after this time period everything is okay................during this time period, i saw msgs erroring in PI in SXMB_MONI transaction giving HTTP 503 Service not available msg and giving HTML error as ICM started but no server with HTTP connected.................then after this time-period, these error msgs were restarted automatically because of RSXMB_RESTART_MESSAGE report which is scheduled in backgroud.............
i want to analyze what happened during this time period..............
From the above HTML error, i analyzed that J2EE engine was down.............
From ICM trace i got that a server node with some number has been dropped from load balancing list, then its HTTP service was stopped, then later this server node was added to load balancing list, then its HTTP service was started and then msgs started getting processed............
i think this server node is linked to CI1 instance.............
So my questions:
1. why CI1 was dropped from load balancing list - what happened at that point of time - how to analyze it.......
2. even if CI1 was not working, why did not the system switched to CI2 immidiately.......
3. how did CI1 automatically got added in the load balancing list............
Plz help me to analyze this situation..........

please gone through this links i hope it will help you.

Unable to connect copied vhd files to VM Hyper-v high availability cluster.

Hi
I have my VMs VHD files stored on my SAN and I have a copied one of the LUNs containing a vhd file which I have then exported to the shared storage of the hyper-V cluster which is just like and other VHD. The problem comes when trying to connect this
copied vhd to the VM which still uses the original VHD . The system refuses reporting that it cannot add the same disk twice..
These are two different VHD files
I have: renamed the new file, changed the disk ID, changed the volume id and using vbox (because it was the only way I could find do it ) changed the uuid of the vhd file. But still no joy.
I can connect the volume to any other VM without any issues, but I need to be able to connect it to the same VM..
I'm not sure how Hyper-v is comparing the two VHD files but I need to know so I can I can connect the copy VHD without having to copy all its contents to a new VHD which is impractical..
Anyone got any ideas or a procedure??
windows 2008 R2 cluster with 3par SAN as storage.
Peter

Hi perter,
Please try to refer to the following items :
1. create a folder in the LUN , then copy the problematic VHD into it ,attach the copied VHD to original VM.
2. copy the problematic VHD file to another volume ,then attach it to original VM again .

How to configure current SQL high availability cluster using mirroring with dedicated replication NICS?

We have a current HA cluster at center1 which is mirrored to another HA cluster in center2. We have several instances already installed and working which are using one NIC for data and replication. We want to prevent mirror failovers by
configuring a NIC on a replication network which has no DNS server. What are the steps to configure the current SQL instances to use this dedicated NIC for mirror replication?

Hi dskim111,
You can refer the following step by step article to create the dedicated mirroring NIC,

Highly Available Cluster-wide IP

We have the following situation
1>. We have a resource group hosting samba
2>. We have one more resource group hosting a java server.
We need to make both this resource group dependant on a common logical hostname.
Do we create a separate resource group with a logical hostname resource. In this case even if the adpater hosting the logical hostname goes down, the resource group is not switched since there is no probe functionality for LogicalHostname.
How do we go about doing this

Hi,
from your question I conclude that both services always have to run on the same node, as they have to run where the "common" logical IP is running. How about putting both services into a single resource group? This seems to be the easiest solution.
In most failure scenarios of logical IP addresses, a failover should be initiated. I must admit that I have never tested a RG which consisited only of a logical IP address.

SAP ECC 6.0 SR3 Cluster failover not working in AIX with DB2 UDB V9.1 FP6

Hi Gurus,
We have installed the SAP ECC 6.0 SR3 High Availability with DB2 UDB V9.1 FP6 in AIX cluster environment.
After installation we are doing the cluster fail test.
Node A
Application Server
Mount Points:
/sapmnt/<SID>
/usr/sap/<SID>
/usr/sap/trans
Node B
Database Server
Mount Points:
/db2//<SID>
The procedure followed to do the cluster failover:
We have down the cluster on Node A and all the resources of the Node A has been moved to Node B.
On Node B when we issued a command to start the SAP. It says u201Cno start profiles foundu201D
WE have down the cluster on Node B and moved the Resource from Node B to Node A . There the db2 User IDu2019s are not available. We have crated the user Idu2019s manually on Node A. however it did not work.
Please suggest the procedure to start the sap in cluster failover.
Best Regards
Sija

Hi Sija,
Can i have detailed scenario in your cluster configuration.
Means you are saying that going to start cluster package manually, if it is right please make sure that you had the same copy of start, instance profiles of NodeA to Node B. Means you need to maintain two startup, two instance profiles for both nodes. In a normal situation it will picik the profile of node A to start databse from A node. But in a failover situation it will not pick node A profile to start, it should pick Node B s profiles.
Just make a copy from node A and change the profile name accordingly to Node b. Then try to restart.
