Installation Cluster SAP ECC DB2

Hi experts,
I´m installing SAP ECC with DB2 in a Windows MSCS environment. I already installed all the critical components in the cluster, and now I need to install the CI. I´m using only 2 nodes. I have the following doubt:
Do I need to install a local CI in the first node and the local DI in the second node and that is enought in case of failure?
Or
Do I need to install a local CI in the first node and then a local CI in the second node too?
In this context CI and DI is the same?
Because in the installation guide the paragraph is a little bit confuse:
To protect system components that are non-SPOFs, for example application servers, you have to install them as multiple components. In this case you must install at least two application servers (one central instance and at least one dialog instance) on two different hosts.
Thanks a lot.
Kind Regards

Hi,
>> Do I need to install a local CI in the first node and the local DI in the second node and that is enought in case of failure?
How did you started the installation? You should perform the steps, under "High-Availability System" So, you will install ASCS first. Then, database instance, ERS, Central instance and Dialog instance
>> To protect system components that are non-SPOFs, for example application servers, you have to install them as multiple components. In this case you must install at least two application servers (one central instance and at least one dialog instance) on two different hosts.
It means that you should have 2 application servers. If one fails another will take all the resources and continue to the service. In short you will anstall 2 application servers in the HA installation.
Read and follow the installation guide, very carefully.

SAP ECC 6.0 installation in windows 2008 clustering with db2 ERROR DB21524E

Dear Sir.,
Am installing sap ECC 6.0 on windows 2008 clustering with db2.
I got one error in the phase of Configure the database for mscs. The error is DB21524E 'FAILED TO CREATE THE RESOURCE DB2 IP PRD' THE CLUSTER NETWORK WAS NOT FOUND .

please help me since am already running late with this installation to run the db2mscs utility to Create resource.
Best regards.,

Edited by: Manjug77 on Oct 29, 2009 2:45 PM

Hello Manjunath.
This looks like a configuration problem.
Please check if IP_NETWORK is set to the name of your network adapter and
if your IP_ADDRESS and IP_SUBNET are set to the correct values.
Note:
- IP_ADDRESS is a new IP address that is not used by any machine in the network.
- IP_NETWORK is optional
If you still get the same error debug your db2mscs.exe-call:
See the answer from Adam Wilson:
Can you run the following and check the output:
db2mscs -f <path>\db2mscs.cfg -d <path>\debug.txt
I suspect you may see the following error in the debug.txt:
Create_IP_Resource fnc_errcode 5045
If you see the fnc_errcode 5045
In that case, error 5045 which is a windows error, means
ERROR_CLUSTER_NETWORK_NOT_FOUND. This error is occuring because windows
couldn't find the "public network" as indicated by IP_NETWORK.
Windows couldn't find the MSCS network called "public network". The
IP_NETWORK parameter must be set to an MSCS Network., so running the
Cluster Admin GUI and expanding the Cluster Configuration->Network to
view all MSCS networks that were available and if "public network" was
one of them.
However, the parameter IP_NETWORK is optional and you could be commented
out. In that case the first MSCS network detected by the system was used.
Best regards,
Hinnerk Gildhoff

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.

Cluster Error SAP ECC EHP5 using DB2

Hi, I´m installing SAP ECC EHP5 over Windows Server 2008 R2 in MSCS using DB2 as Database.
I follow the steps in the installation guide and the first node was sucessfully installed. My problem is that when I execute the second step of the installation (database installation), in the sub-step "Now cluster the database" , after installed the database in the second node and run the utility db2mscs the following error occurs when I tried to initialize the DB2 service:
"An error occurred while attemping to bring the resource ''DB2 Server' online"
Error code: 0x8007138f
The cluster resource could not be found
Could you please give any hint to continue the installation?
Thanks a lot.
Kind regards

I made a mistake and opened the thread 2 times. The other one was answered.

AIX6.1+HACMP+DB2 9.1+SAP ECC 6.0 High Availablity Installation

Dear All,
This is to request you that anyone having a sure shot Installation guide /Solution to Install SAP in High Availablity using following platform.
1. AIX 6.1
2. DB2 9.1
3. HACMP
4. ECC 6.0 SR 2
Note: Not Failover by scripting. High Availablity like Microsoft MCSC. Complete installation on Virtual host, IP and Shared File system/stirage.
Please....................................................
Regards
Dharmendra

Installing SAP NW07 SR3 with DB2 on AIX HACMP
Scenario:-
DB will run on Node A
SAP CI will run on Node B
If node A fails DB will failover to Node B
If node B fails CI will failover to Node A
Shared SAP and DB filesystem are in SAN
Filesystems will failover accordingly
Requirements:-
SAP NW07 SR3 DVDs
AIX Node A
AIX Node B
HACMP supports node failures. We are not using HACMP to probe Application (SAP/DB) failures. i.e. if SAP or DB process crashes HACMP will not failover the resource groups.
/etc/hosts should have IPs of both nodes
Assumptions:-
PRD = PRD
Node A hostname: dbserver
Node B hostname: ciserver
Shared filesystems
These filesystems can be moved/ failed over (unmounted /mounted) from one node to another.
/usr/sap/PRD
/sapmnt/PRD
/db2/PRD
/db2/db2prd
/db2/PRD/sapdata1
/db2/PRD/sapdata2
/db2/PRD/sapdata3
/db2/PRD/sapdata4
/db2/PRD/log_dir
/db2/PRD/db2dump
Users and Groups will be created by SAPINST.
Please make a note of the UIDs as we have to use the same UIDs and GIDs on other node as well.
User Home directory:- For prdadm please use a home directory on shared disk
For e.g. /usr/sap/PRD/home/prdadm
Use Distributed Installation option in SAPINST
Installation steps:-
Node A:
Mount SAP filesystems
Mount DB2 filesystems
Check /etc/hosts that IP of both nodes are available
Ping both nodes and check the IP address
Check output of command ifconfig u2013a and confirm that both IPs are available
Start SAPINST with SAPINST_USE_HOSTNAME option.
For e.f. ./sapinst SAPINST_USE_HOSTNAME=dbserver
Step 1: Global host preparation (this should be easy to finish)
Step 2: Database instance installation
During this step note down UIDs and GIDs created by sapinst.
During this step please choose /usr/sap/PRD/home/prdadm as user home for prdadm user.
With SR3 DVDs db2 software will be installed in /db2/PRD/db2_software
Step 3: Install SAP Central Instance with SAPINST_USE_HOSTNAME=ciserver
Stop / Start SAP -> Login and confirm SAP instance is running fine.
Shutdown SAP and DB2
Add entries in .rhosts in home directory on user prdadm and db2prd
For example in /usr/sap/PRD/home/prdadm/.rhots
<IP Address of Node A> prdadm
<IP Address of Node B> prdadm
<all possible IP address> prdadm
Similarly for /db2/db2prd/.rhosts
<IP Address of Node A> db2prd
<IP Address of Node B> db2prd
<all possible IP address> db2prd
Node B:
Move SAP resources from Node A to B (i.e. SAP filesystems should become available on Node B)
DO NOT MODE DB RESOURCES, Let it stay on Node A alone.
Create /db2/PRD and /db2/db2prd directories (this should have some free space, 10 GB is good to go)
Start SAP installation under Distributed installation option
Step 1: Global host preparation
Temporarily change /etc/hosts and make the IP of dbserver same as ciserver.
dbserver line should be written above ciserver line
i.e. u2018ping dbserveru2019 and u2018ping ciserveru2019 should return same IP address on Node B (NOT NODE A)
Step 2: Database instance installation with option SAPINST_USE_HOSTNAME=dbserver
During this installation, make sure UIDs and GIDs are given same as in Node A.
You can confirm the UIDs from /etc/passwd and GID from /etc/group
Also, make sure you specify user home for prdadm as /usr/sap/PRD/home/prdadm
Once installation starts ABAP Load and one or two jobs are completed, please cancel the installation.
as db2prd
db2stop force
db2start
db2 connect to PRD
It should be successful. This confirms the DB2 is setup properly.
db2stop terminate
db2stop force
rm u2013r /db2/db2prd/*
rm u2013r /db2/PRD/sapdata1
rm u2013r /db2/PRD/sapdata2
rm u2013r /db2/PRD/sapdata3
rm u2013r /db2/PRD/sapdata4
rm u2013r /db2/PRD/log_dir
rm u2013r /db2/PRD/db2dump
Retain these directories so that you can mount the shared filesystems from Node A to Node B during failover.
Change and correct IP address in /etc/hosts of host dbserver, which we changed temporarily earlier.
Failover DB resources to Node B
Check if all DB2 filesystems are correctly available.
On Node A, check and double confirm that there are no files/directories under /db2 and its subdirectories. i.e. all filesystems have come to Node B.
In our case there was one filesystem /db2/PRD/db2prd which did not come to node B and we had to struggle a lot to find the same.

File system for SAP ECC, EP , BI and CRM installation on Solaris/DB2

Hello,
We are going to implement SAP ECC 6.0 with EP 7, BI and CRM on Solaris operating system with IBM DB2 database.
All these applications are going to be installed on single server, as being a basis person, I know this is not all recommended.
But due to client's requirement and keeping cost factor in mind I need to install all these application on single box.
Now here I need your help. as I basis person, I know the required Solaris file system for SAP ECC 6.0 but not having any Idea about other application like EP/ CRM and BI .
If anyone able to help me with required Solaris file system. it will be great help.
Please let me know if there is any query.
Thanks.

> All these applications are going to be installed on single server, as being a basis person, I know this is not all recommended.

Why not using Solaris zones/container? This decreases the administrative amount tremendeously since you will deal as with "single machines" but they all run together on one box.
> Now here I need your help. as I basis person, I know the required Solaris file system for SAP ECC 6.0 but not having any Idea about other application like EP/ CRM and BI .
So you'd need to read the installation guides

The cluster resource could not be found-SAP ECC on Windows Server 2008 MSCS

Hi,
I'm installing SAP ECC 6.0 on Windows server 2008 MSCS Cluster. As mentioned in the guide, i've created a service and added a resource.
I was able to successfully configure the DB installation and cluster configuration. But when I start the ASCS installation, the installation fails when it tries to create system folders with the following error.
Error when sharing file system export (share) saploc : The cluster resource could not be found
I'm using a user with domain admin access and also a member of the local administrators group. I've even tried to install using the domain administrator user but still the problem exists.
Can anyone please let me know where am I going wrong ?
NB: The host on which I'm installing is not a domain controller but it is a member of a domain.
Regards,
Varadharajan M

Yes Krishna,
I've not created any shared folders manually and I've used the "Use domain of current user" option.
Actually SAPINST has created the usr and sap folder in the SAP drive (say E: drive) which is a clustered disk. The name of that clustered sidk is "Clustered Disk 1". I could able to open up the shared directories available in that SAP virtual host by issuing
<SAPGRP>. I don't know where am I going wrong:( I've also opened a call with a SAP and waiting for their reply.

Have you any cluster script ( HACMP Cluster script for SAP ECC 6.0 ) ?
Thanks & Regards,

Hello, I'm doing a "Plant ECC6 to do a test disatre / Recovery.
During the installation, I would use the same <sidadm> existing as it is in the PRD.
If I tell you to install it during the same <sidadm> it will overwrite what already exists, or do I just enter the password of existing <sidadm>?
