Central NetWeaver Installation and DB Instance on same host?

HI all,
Would like to ask a question about NetWeaver installation.
If I choose central installation, means Central Service Instance, DB Instance and Central Instance will be on the same host, but can my DB, say SQL Server reside on separate host?
If not, is it correct that I have to choose distributed installation? So if distributed installation, can I install Central Service instance and Central intance on one host, and DB instance and SQL Server on another host?
Thanks,
Kelvin

Hi KL:
You can get this answer directly from the Installation Guides.
You can download the installation guides for NetWeaver under: https://service.sap.com/instguides
Hope this helps!

Multiple dialog instances on same host for different System

Dear Sir,
I install two dialog instances on same host ,one for DEV one for QAS.
First I install dialog instance for DEV and startup with no error.
Second dialog instance for QAS install with success end ,but can not start dispatchers.

It seem that first startup dialog instance already start MSSQLSERVER -m sap-dev and SQLSERVERAGENT -m sap-dev, so next instance can not start again ,and cause NICONN_REFUSED.
Could someone help me?
Thanks

It appears to be possible, at least in IDM 7.1
The release notes and Installation guide reference a setting called waveset.serverId that you set in your application server startup script like so:
-Dwaveset.serverId=Name
This would allow each JVM to identify itself differently from any others running on the same physical server.
I haven't tried this yet myself, so caveat emptor.

This is also covered in the guides.
Are you going to use VxFS? If you´re on Solaris 10 try ZFS - MUCH easier to configure and handle!

How to divide SAPS when having two instances on same host

Hello
I wander how to divide SAPS when having two instances on same host. By looking at st06?
Thank you in advance

Yes SAPS is nothing but the CPU power used by the SAP systems. SO if you have 2 SAP systems stacked on the same server, check the CPU utilization over a period of 7 - 10 days, average out & that should give you a fair bit of idea.

ASM and database instance sharing same home. Can i split them?

Hi I am running on 10.2.0.1.0 in a 2 server RAC cluster on linux. ASM and db instance are sharing the same home.
I now need to upgrade my ASM instance and clusterware to 11g, but just want to keep my db at 10g because of some compatability issues ( i will probably still need to upgrade the db to 10.2.0.5.0).
Is there any way i can split my Oracle Home so that i now can upgrade my ASM home and keep my prod DB instance still at 10g?
Thanks again. John

Multiple IDM instances on same host

Can multiple Identity Manager app server instances be run on the same host, connecting to the same db? If so, how is this accomplished. From what I see Identity Manager instances attempt to register themselves using the host name. Is there a property in the properties file that can set a unique name?

It appears to be possible, at least in IDM 7.1

I downloaded Firefox Optimized for Yahoo on my PC and get an error message about every 15 seconds: Java Script/ Uninstall set. I deleted Firefox and did a new download/installation and am getting the same problem.

:I went to Mozilla's website and downloaded the Firefox Optimized for Yahoo, following the directions. The download installed easily, but when it opened my Yahoo web page (I already had an account with them), the Java Script error message "Uninstall set!" immediately began alerts, and kept repeating the alert about every 15 seconds. I got the same result even after uninstalling Firefox and downloading a fresh installation. I am only getting this alert via Firefox; I do not get it when using my Yahoo page with Google. Thanks.

Problem in accessing second database instance on same host (ORA-12514)

Hi,
I had a database ICMDB installed on my machine. After that i created a second database instance (Service name: BI_APPS) using DBCA on the same machine. Using NETCA i also created a new listener OracleOraDb11g_home1TNSListenerBI_APPS_LISTENER on port 1522 on my machine. Then i configured this listener to listen for connections to service BI_APPS by adding the following to my tnsnames.ora:
BI_APPS_LISTENER =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.109)(PORT = 1522))
Then i changed the port in my tns entry for BI_APPS to 1522 as follows:
BI_APPS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.109)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = BI_APPS)
I then restarted the following services:
OracleOraDb11g_home1TNSListener
OracleServiceBIAPPS
OracleOraDb11g_home1TNSListenerBI_APPS_LISTENER
After this, when i try to access my first DB ICMDB via toad, the connection is successful. However, when i try to access the service BI_APPS i get the following error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
What am i doing wrong? Here is the content of my files:

Hi Ed,
I understand your point, however whenever i have tried to use the same listener to access my second instance, this is the error i have always received:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
That does not indicate you need a second listener.
And, after deleting the listener.ora file ,if i try the the command lsnrctl start, i get the error:
ORA-12560: TNS:protocol adapter error
Hence i restored the files. What do i do?
I've never experienced a 12560 trying to start a listener. I'll need to see if I can create a test system on Windows and try to recreate. Will be a good subject for my blog, that has been too long with no new content.
Since this is windows, I'd first check that the Windows service for the listenr is started.
Whatever, multiple listeners is NOT the solution.

Production and development OBIEE on same host

Hi!
I have a problem!
I installed with different users (oracle and bitest) one ias 10.1.3.1 and BIEE 10.1.3.3.2. The installation finished successfull without errors and warnings. I can start The IAS instances successfull and they work fine. But. I set the port of first nqserver to 9713 and the seconds 9703 on the NQSconfig.ini and I set the odbc.ini too. So, I start the first nqserver on 9713 works fine, but both IAS instance connect to that (run on 9713) nqserver. I don't know, did I set the all parameters perfectly?
Pls Help!
Thanks!

Running Sun App Server 7 and 8 on the same box

Hello,
Are there any known issues with running Sun App Server 7 and 8 in the same host box ? Currently I am encountering some class not found exceptions with Sun App Server 8 . Sun App Server 7 runs just fine.
Thanks,
Aswin.

It's not advisable to run separate installations of
ColdFusion 7 and ColdFusion 8 single server on the same machine the
re are several services that will try to use the same ports.
However, you can install ColdFusion Enterprise using the
multi-server configuration and then deploy the J2EE versions of
ColdFusion to JRun. You can change the JVM that each instance uses
(we recommend the latest 1.4 for CF7 and the latest 1.6 for CF8),
and everything should run fine.
ColdFusion itself is essentially just a J2EE application, the
J2EE server itself is JRun 4. So the specific answer to your
question is "don't install 2 copies of JRun 4 to the same machine".
But yes, it's 100% possible, I'm running this configuration in my
own development environment.

Calendar Server and Email Server on Same Machine - Email Issue

Hi.
I've installed email and calendar on the same host. The email domain for test purposes is the name of the machine. I noticed in the configuration guide, it says that if you put the calendar server and email server on the same machine you need to configure sendmail.cf and modify incoming rules in order to get email reminders from Calendar to Email. I have done this but am still not able to. I get the emails kicked back to root and they say:
553 5.3.5 System Config Errors
553 5.3.5 <machine name> config error: mail loops back to me (MX problem?)
Has someone seen this before?
Thank You,
Matt

Hi Russ,
We have the same problem as Matt.
We have properly set up OCS Email it works well both inside and outside our network.
The only thing that appears not to be working is the email notification capabilities of OCS Calendar.
We have changed sendmail.cf as stated in the documentantion.
we are using -
RedHat Advanced Server 2.1,
sendmail 8.11.6
bind 9.1.3
I would be very gratefull of any information on this, as we're out of ideas...

Nexus 1000V - port-profile for VSM and VEM on same host

Hello,
I'm trying to run the VSM and VEM on the same host. At first I connected the VSM to the vSwitch. This works fine. Then I tried to move the VSM behind its own VEM.
I have 3 different VLANs for management, control and packet traffic. Is it possible to connect the three VSM interfaces (management, control and packet) to only one port-profile, in which these three different VLANs are configured in a trunk? Or do I have to configure for each interface a separate port-profile, if I am using three different VLANs?
Thanks
Tobias

Hello,
The VSM does not emit VLAN-tagged frames. Therefore, its ports need to be configured in access mode. If your Control and Packet VLANs are the same, you could use the same port profile for both.
Please make sure that the access VLAN is a system VLAN for all three ports.
On a related note, if the VSM's storage is on NFS or iSCSI, the storage vmknic needs a system port profile as well. More info at:
