CSM Loadbalancing multiple server VLANs

Is it possible to loadbalance servers located in multiple VLANs using the CSM? I have a need to loadbalance sites the may be located in different VLANs/Subnets but I am unable to consolidate them into a single subnet.

Its possible.
Just make sure that return traffic from Real Servers should not bypass CSM.
This can be achieved by using one of the three methods.
1. By configuring CSM's server Vlan IP as the Default Gateway on Real Servers.
Or
2. Using Source NAT on CSM.
Or
3. Using PBR

CSM + multiple client vlan

If a CSM has more than one client VLANs, connected to different routers, how does CSM decide what path to take when server initiate a connection? in other words is there a way to associate server vlan(s) to client vlan?

The term client vlan actually represents an interface between the CSM and the 6500's L2 and L3 vlan.
If you have multiple routers connecting to your 6500, they will be associated vlan(s) n the 6500 as any other vlan is...you define the balanced servers default gateway as the alias address within the server vlan define on the CSM...the CSM then forwards this to the gateway defined on the csm client vlan which is also the 6500's L3 interface. The 6500 then uses it's own routing table to define where the next hop for this destination is.
Hope this helps

DHCP from CSM Server VLAN

Is there a way to add a helper-address (or something similiar) to the CSM server VLAN? My unix team is planning on setting up a PIXE server boot server and a few of their servers that would need the ability to boot from it are in the server VLAN that my CSM hosts, I'm not sure how a DHCP request would ever leave that VLAN is I don't have some way of adding a helper address to it.
Thanks for any help....Jeff

Hello-
The CSM does not have any DHCP Helper address equivelants. However, you can configure the server VLAN in question in a bridged mode with a vlan on the MSFC that does do DHCP and the CSM will bridge the BOOTP requests to it.

I've got a problem with dynamic vlans. Trying to figure out configuration for the topology similar to the one in the picture.
I’ve got four vlans for PCs, one vlan per department. I have to add fifth vlan (50) for devices that can be connected to any of the three switches: A, B, C. these devices need to be on their own vlan, no matter to which switch they are connected to. On the other hand, PCs connected to any port on those switches should be assigned to appropriate vlan (10,20,30 or 40).
I was thinking about using dynamic vlans with list of mac addresses of devices that need to be on vlan 50 but not sure what to do with PCs. I don’t think I can use fallback vlan as I can set up only one fallback vlan for whole network and not per switch or port.
I cannot use list of mac addresses of all pcs as there’s simply too many of them (my network is way bigger than in the picture, I simplified it only to present the idea). I imagine I would need multiple fallback vlans for different switches.
Has anyone got any idea that could help me please? Maybe there’s some other and easier way?

In new software (for Cisco switches) we provide multiple fallbacks for MAC authentication (MAB):
1. 802.1x
2. web authentication
3. guest vlan (if no supplicant on the PC)
4. auth fail vlan (if radius denies you access)
So you could keep a list of MAC addresses for vlan 50 and do MAB for these devices if MAB fails you can use 802.1x for your PCs.
This will require configuring 802.1x supplicants on all PC (Windows comes preloaded with one) and maintaining a radius of users who are able to log into the network. A lot of people use their Active directory pre-existing database as a backend to store their usernames and passwords for user authentication with dot1x.
With using both dot1x and MAB you can now distinguish easily between two different processes and use your radius server to assign vlans based upon almost anything you can think of.

How Can i specify multiple server names in rwservlet.properties file?

How Can i specify multiple server names in rwservlet.properties file without clustering?
I am using oracle 10g Application server. we have 3 servers Repsvr1, RepSvr2 and RepSvr3. Now i need to configure rwservlet.properties file to point to these servers based on any running report. i got 3 keymap files with reports info.
Sample entry in the key map file is:
key1: server=Repsvr1 userid=xxx/yyy@dbname report=D:\Web\path1\path2\reports\Report1.rdf destype=cache desformat=PDF %*
key2: server=Repsvr2 userid=xxx/yyy@dbname report=D:\Web\path1\path3\reports\Report2.rdf destype=cache desformat=PDF %*
rwservlet.properties file letting me to enter only one servername. Even though i merged all 3 keymap files into 1, still i have the server name issue. If i leave the server to the default name still i am getting the below error.
REP-51002: Bind to Reports Server Repsvr1 failed. However, i know the default rep_<servername> would be used incase we dont have SERVER=<value> parameter in the rwservlet.properties file.
If i specify the servername in the rwservlet.properties file then only Repsvr1 reports are working fine and other 2 server reports are giving the same error like
REP-51002: Bind to Reports Server <<Server Name>> failed.
how can i configure the info which will work all 3 reports. 2 Port servers are invoking using oracle forms and report server is invoking using ASP pages.
If i specify Server name & Key map file in rwservlet.properties one at a time, all the reports are working without any error, whenever i am trying to integrate all 3 to workable i am getting binding error. if i exclude the server from rwservlet.properties still i am getting the same error.

My RELOAD_KEYMAP setting is YES only.As i said If i specify Server name & Key map file in rwservlet.properties one at a time, all the reports are working without any error.
keymap file entries
key1: server=Repsvr1 userid=xxx/yyy@dbname report=D:\Web\path1\path2\reports\Report1.rdf destype=cache desformat=PDF %*
key2: server=Repsvr2 userid=xxx/yyy@dbname report=D:\Web\path1\path3\reports\Report2.rdf destype=cache desformat=PDF %*
If i use http://server.domain:port/reports/rwservlet? cmdkey = key1 should bring the report from Repsvr1 and http://server.domain:port/reports/rwservlet? cmdkey = key2 should bring the report from Repsvr2, but i am getting an error from Repsvr2 saying that REP-51002: Bind to Reports Server repsvr2 failed.
Only Servername Repsvr1 is in rwservlet.properties file. Now what is the best option to by pass the server from rwservlet.properties file and should be from keymap file. if i comment server name in rwservlet.properties file still i am getting REP-51002: Bind to Reports Server <<Server Name>> failed error for both keys.

Load Data from a table on one server's database, to the same table structure in multiple server databases

Hi,
I have a situation where i have to load data from one server/database table to multiple servers/databases.
Example:
I need to load data from dbo.TABLE_A (on Server: Server_A & Database: Database_A) to the same table on the list of server databases like
Server: Server_B , Database: Database_B
Server: Server_C , Database: Database_C
Server: Server_D , Database: Database_D
Server: Server_E , Database: Database_E
Server: Server_F , Database: Database_F
Server: Server_G , Database: Database_G
Server: Server_H , Database: Database_H
so on and so forth on 250 such server database combinations.
The table structure is the same on all the servers.
If i make the source or destination dynamic, it throws an error while mapping ?
I cannot get Linked server permissions and SQL Server Config thing doesn't work as well.
Please suggest on how to load data from one source to multiple server/databases.
Thank you.

I just need to transfer one table's data. its like i have to use a query to pick data for
the most recent data. So i use something like, select A, B, C, D from dbo.table where ETL_TIMESTAMP > (the max(etltimestamp) in the destination on different server). There are no foreign key relationships and the data should not be truncated. it just had
to append the new records.

Does GRC AC 5.2 supports multiple server nodes

Hello Experts,
Does GRC AC 5.2 is supported with multiple server nodes.
Thanks
Davinder

Thanks once again Harleen,
For AC 5.2 i will raise an SAP OSS message and share the results with community.
For AC 5.3, we have configured SAP logger and make neccesary changes in NWA. But log information over here is not as detailed (background job information is missing) as we get in RAR -> Background Jobs ->View Logs.
I have generated another thread for this issue (GRC AC 5.3 Logging strategy in multi server nodes), would appreciate if you can show some light on this issue
Thanks

Pros and Cons of Application Isolation/Multiple server instances?

Hi. I'm setting a new server using ColdFusion Enterprise with Apache to migrate several web application from and old server with ColdFusion 7 server. I'm currently doing research regarding multiple server instances in order to have a separate server for production apps and another for development apps (see http://help.adobe.com/en_US/ColdFusion/10.0/Admin/WSc3ff6d0ea77859461172e0811cbf363c31-7ff 5.html and https://wikidocs.adobe.com/wiki/display/coldfusionen/Using+Multiple+Server+Instanceshttp:/ /). In addition, I'm also doing research regarding application isolation to have separate production application in separate servers. I'm trying to identify all pros and cons for both "Application Isolation" and "Multiple Server Instances" to make a decision on whether I will proceed in applying these techniques. I have found several links that talk about some of the advantages but have not been able to find anything regarding possible disadvantages. Have anyone in this forum has used any of the techniques, and can provide more information/experiences regarding the pros and cons?

Hi Ricardo_Lorenzo,
Whether to go for Multiserver instances or Single server, is totally a user requirement based decison. If a user has Single website, or multiple websites (of the same nature, in terms of functionality), usually the part of same domain, then they would go for Single sever installation. One single instance will handle the requests from all the websites (if there are multiple). There would not be a clustering/failover setup within ColdFusion and can use the ColdFusion Standard or Enterprise version.
On the other hand, if a user has multiple websites, all with different functionality and have multiple applications (may or may not) running, then they can go for Multiserver installation. Each website can be configured with individual instances. Clustering can be done within ColdFusion if needed. One would need an Enterprise license of ColdFusion for the same.
Hope this helps.

Multiple Server nodes in Java Instance

Hello Experts,
We have NW 700 SP17 Java system running with 5 server nodes. Would appreciate, if you clarify following doubts:
1. How can we check which user has landed up into which server node.
2. Is there any possibility of check logs (like defaulttrace,etc) for all the server nodes from a single location (like NWA).
3. How can we check the load on each of the server node.
4. Where can we find documentation on configuring and operating Java instance with multiple server nodes.
Thanks
Davinder

1. How can we check which user has landed up into which server node.
Ask the user to execute this: javascript:document.cookie
while they are in the Java pages.
2. Is there any possibility of check logs (like defaulttrace,etc) for all the server nodes from a single location (like NWA).
- Yes, SAP LogViewer should give you that options
3. How can we check the load on each of the server node -
- Consider configuring Solution Manager Diagnostics, is it very nice tool for Java Load Monitoring
4. Where can we find documentation on configuring and operating Java instance with multiple server nodes
- If you asking about how many nodes requires on a java instance, you might want to use the SAP Quick Sizer to size your systems, then it will give you total Memory it requirsts then you need to divide that by 2.5 GB (64 bit OS) or for 32 bits they recommend you not to exceed your heap size beyond 1 GB.
Added Nodes is very simple via Configtool, then you might have to setup your server with same settings as your previous nodes.

Running Multiple Server Instance in Weblogic Server

Hi
I am using Weblogic 5.1.0 with SP6. I am trying to run multiple server
instances
of Weblogic Server. The one that comes by default is "myServer".
My question is if i were to create multiple server instances, do i need to
copy the
weblogic.properties file in each of folder corresponding to respective
application
server instance. I am not using Clusters.
Also if i need to include some classes or jar files in my application server
instance
classpath, how do i do it. cuz in weblogic.properties file i didn't find any
property
corresponding to classpath.
The classpath i need to set is for my creating a JDBC pool for connectivity
to my
AS400 DB2 database using the Type 4 (AS400JDBCDriver) Driver. Is there some
other way to do it.
Thanks in advance

JNDI Lookup for multiple server instances with multiple cluster nodes

Hi Experts,
I need help with retreiving log files for multiple server instances with multiple cluster nodes. The system is Netweaver 7.01.
There are 3 server instances all instances with 3 cluster nodes.
There are EJB session beans deployed on them to retreive the log information for each server node.
In the session bean there is a method:
public List getServers() {
List servers = new ArrayList();
ClassLoader saveLoader = Thread.currentThread().getContextClassLoader();
try {
   Properties prop = new Properties();
   prop.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.sap.engine.services.jndi.InitialContextFactoryImpl");
   prop.put(Context.SECURITY_AUTHENTICATION, "none");
   Thread.currentThread().setContextClassLoader((com.sap.engine.services.adminadapter.interfaces.RemoteAdminInterface.class).getClassLoader());
   InitialContext mInitialContext = new InitialContext(prop);
   RemoteAdminInterface rai = (RemoteAdminInterface) mInitialContext.lookup("adminadapter");
   ClusterAdministrator cadm = rai.getClusterAdministrator();
   ConvenienceEngineAdministrator cea = rai.getConvenienceEngineAdministrator();
   int nodeId[] = cea.getClusterNodeIds();
   int dispatcherId = 0;
   String dispatcherIP = null;
   String p4Port = null;
   for (int i = 0; i < nodeId.length; i++) {
    if (cea.getClusterNodeType(nodeId[i]) != 1)
     continue;
    Properties dispatcherProp = cadm.getNodeInfo(nodeId[i]);
    dispatcherIP = dispatcherProp.getProperty("Host", "localhost");
    p4Port = cea.getServiceProperty(nodeId[i], "p4", "port");
    String[] loc = new String[3];
    loc[0] = dispatcherIP;
    loc[1] = p4Port;
    loc[2] = null;
    servers.add(loc);
   mInitialContext.close();
} catch (NamingException e) {
} catch (RemoteException e) {
} finally {
   Thread.currentThread().setContextClassLoader(saveLoader);
return servers;
and the retreived server information used here in another class:
public void run() {

The application is working for multiple server instances with a single cluster node but not working for multiple cusltered environment.
Anybody knows what should be changed to handle more cluster nodes?
Thanks,
Gergely

Thanks for the response.
I was afraid that it would be something like that although
was hoping for
something closer to the application pools we use with IIS to
isolate sites
and limit the impact one badly behaving one can have on
another.

Illustrator CS6 hangs saving files to local HD while having multiple server share points mounted

Mac OS 10.6
Illustrator CS6
Illustrator CS6 hangs (spinning beach ball) when saving files to the computer's local HD while having multiple server share points mounted.
I am NOT opening or saving the file to or from a server.
The server is mounted so that I can move my saved file to it once complete.
Unmounting the servers fixes the problem and Illustrator CS6 returns to being normal (not causing a spinning beach ball).
This is repeatable, not intermitent.

We were having similar issues working over a network. I believe it's a Mac OS 10.6 issue, something to do with the Mac finder searching for file dates or metadata on the servers. From what I understand, this has been fixed in OS 10.7. We can't yet move to 10.7 and after trying many possible fixes, found that a Mac finder alternative, Path Finder, fixed most server delays. It's not free, but you can give it a 30 day trial to see if it fixes your issue. Here is a link to discussions about other suggested fixes:

Multiple server sessions

Hi,
Should there be any issue mixing objects between multiple server sessions.
We have multiple services that each have each have their own ServerSession.
There are situations where objects retrieved through one ServerSession are ultimately part of an object that is persisted through another ServerSession.
Note: communication between client and services is via RMI and persistence is performed using the mergeWithReferences method.
Example,
- Person object has an Address object.
- Address is retrieved from ServerSession 1 (RMI)
- Person object is retrieved from ServerSession 2 (RMI)
- Address is added to Person and Person is persisted
thru ServerSession 2. (RMI)
The behavior I've observed is inconsistent but ultimately there seems to be problems.
From the example above, occasionally ServerSession2 will attempt to reinsert the Address object into the table.
In the case where Address is read only the cached version of Person in ServerSession2 will have a null Address attribute after persistence even though the database was updated correctly.
What accounts for this behavior?
Thanks
Mark

Marc,
The problem you are seing is related to TopLink's existence checking. When you go to write an object from session 1 into session2 and it does not exist in the cache TopLink assumes the object is new. This is very similar to when you are running in a cluster and your write request ends up in a JVM where the TopLink session has not read in the object you plan to write.
In order to make this work you can change the existence-checking setting, which I don't recommend, or you can alter your pattern for dealing with the UnitOfWork.
When you serialize the object(s) across RMI to the server that is going to do your writing I recommend the following pattern:
1. Acquire UnitOfWork from session
2. Read objects from database
unitOfWork.read(person);
unitOfWork.read(address);
3. Merge objects (unitOfWork merge APIs)
4. Commit UnitOfWork
Step #2 is important here. If you are writing to a session that has the objects cached then no database call is required. If not, the database version will be read in. The merge will copy the values over to the working copy and the commit will calculate and write any necessary changes.
Other recent threads in this forum and the documentation detail the merge options.
