Connect to 11g RAC cluster failing

Hi,
I have a simple java client which tries to connect to the 11g RAC clustered Oracle server on a remote location using oracle thin client. We have been provided the SID of the load balancer and hence the client is not able to connect it. When I try to connect to individual nodes with their respective SID's it is able to connect. The server architect recommends to switch to OCI based client instead of thin client. On doing that I am getting this error "Exception in thread "main" java.lang.UnsatisfiedLinkError: no ocijdbc11 in java.library.path". The client resides on a 64 bit Linux machine.How can I make it work.
Below is the code I am using to connect:
OracleDataSource _source = new OracleDataSource();
source.setURL(mInitConnString); //_mInitString="jdbc:oracle:oci:@ip:port:SID";
source.setUser(mDbUser);
source.setPassword(mDbPass);
mConn = source.getConnection();

It seems that the failover and load balancing features of JDBC do not work with Oracle RAC. As phrased that statement is wrong.
JDBC is an interface. It doesn't do much of anything.
JDBC drivers on the other hand do something.
Oracle has always and still does create a JDBC driver. And so do other companies - for Oracle. The merge will have no impact on that.
Oracle certainly seems to think that RAC does work with their JDBC driver. The following link demonstrates that. (Notice that the page copyright on that page is 2008 so perhaps they have thought so for a while.)
http://download.oracle.com/docs/cd/E13222_01/wls/docs103/jdbc_admin/oracle_rac.html
and the fail over strings connect but without failover. So if I take a rac node down then the sites go down.Far as I know the primary and most significant goal of RAC is to support clusters of servers, so if in fact there isn't in some way to actually do what you are saying then why does Oracle claim that RAC does in fact work in Java? Why does the above link specifically discuss failover/retries within a Java context if it does not in fact work at all?

APEX on RAC cluster

I"m setting up a 11g RAC cluster and will be using APEX. My question is:
can http server run off of all nodes in the cluster or just one?

Hello Kevin,
When I run following sql statement:
select DBMS_XDB.getHTTPPort from dual;to check if APEX listener is running the gethttpport return 0.This command queries the port of the database internal XDB HTTP Server. The return value 0 means it is disabled.
If you want to use APEX Listener, you have to install it according to the corresponding documentation. See
- [url http://docs.oracle.com/cd/E37097_01/doc/install.42/e35123/otn_install.htm#BABJJAGF]Downloading from OTN and Configuring Oracle Application Express Listener in APEX 4.2 Install Guide on how to configure your APEX properly.
- [url http://docs.oracle.com/cd/E37099_01/doc/doc.20/e25066/install.htm#CHDIDHCD]APEX Listener 2 Installation Guide on how to install and configure APEX Listener 2.
Note that APEX Listener support starts with APEX 4.0. It also works with previous APEX versions such as your 3.2, but is not officially supported (and not documented). I'd recommend to update to the recent APEX release anyway, as it offers several new features, includes several bug fixes, ...
Also note that you can't configure RESTful services for APEX Listener 2 on APEX releases prior to 4.1.

Routing all connections through a one node in a 2 node RAC cluster

Hi everyone
My client has the following requirement: an active/active RAC cluster (eg node1/node2), but with only one of the nodes being used (node1) and the other sitting there just in case.
For things like services, i'm sure this is straightforward enough - just have them set to preferred on node1 and available on node 2.
For connections, I imagine I would just have the vips in order in the tns file, but with LOAD_BALANCING=OFF, so they go through the tns entries in order (i.e node 1, then node 2), so this would still allow the vip to failover if node 1 is down.
Does that sound about right? Have I missed anything?
Many thanks
Rup

What is the reason for a "+just in case+" node - and when and how is is "enabled" when that just-in-case situation occurs?
This does not many any kind of sense from a high availability or redundancy view.

Does that sound about right? Have I missed anything?Won't work on 10g - may not work on 11g. The Listener can and does handoff connections, depending on what the TNS connection string say. If you do not connect via a SID entry but via a SERVICE entry, and that service is available on multiple nodes, you may not (and often will not) be connected to instance on the single IP that you used in your TNS connection.
Basic example:
// note that this TEST-RAC alias refers to a single specific IP of a cluster, and use
// SERVICE_NAME as the request

This issue aside - how do you deal with just-in-case situation? How do you get clients to connect to node 2 when node 1 is down? Do you rely on the virtual IP of node 1 to be switched to node 2? Is this a 100% safe and guaranteed method?
It can take some time (minutes, perhaps more) for a virtual IP address to fail over to another node. During that time, any client connection using that virtual IP will fail. Is this acceptable?
I dunno - I dislike this concept of your client of treating the one RAC node as some kind of standby database for a just-in-case situation. I fail to see any logic in that approach.

Is there a way to config WLS to fail over from a primary RAC cluster to a DR RAC cluster?

Here's the situation:
We have two Oracle RAC clusters, one in a primary site, and the other in a DR site
Although they run active/active using some sort of replication (Oracle Streams? not sure), we are being asked to use only the one currently being used as the primary to prevent latency & conflict issues
We are using this only for read-only queries.
We are not concerned with XA
We're using WebLogic 10.3.5 with MultiDatasources, using the Oracle Thin driver (non-XA for this use case) for instances
I know how to set up MultiDatasources for an individual RAC cluster, and I have been doing that for years.
Question:
Is there a way to configure MultiDatasources (mDS) in WebLogic to allow for automatic failover between the two clusters, or does the app have to be coded to failover from an mDS that's not working to one that's working (with preference to a currently labelled "primary" site).
Note:
We still want to have load balancing across the current "primary" cluster's members
Is there a "best practice" here?

Hi Steve,
There are 2 ways to connect WLS to a Oracle RAC.
1. Use the Oracle RAC service URL which contains the details of all the RAC nodes and the respective IP address and DNS.
2. Connect to the primary cluster as you are currently doing and use a MDS to load-balance/failover between multiple nodes in the primary RAC (if applicable).
In case of a primary RAC nodes failure and switch to DR RAC nodes, use WLST scripts to change the connection URL and restart the application to remove any old connections.
Such DB fail-over tests can be conducted in a test/reference environment to set up the required log monitoring and subsequent steps to measure the timelines.
Thanks,
Souvik.

If you do not need XA connectivity then you are free to do whatever you want,
but it is not supportable for XA. We do document fairly well what we recommend
for RAC connectiviity.

Tnsentries in 11g RAC

(CONNECT_DATA =

whem am giving tnsping test and tnsping test1 from any client , it works fine..connection succeded..
but when am trying to connect using sqlplus user@test
am getting the error :

whereas I can able to connect sqlplus user@test1
Any ideas ?

LOCAL_LISTENER IS ALREADY set to the listener name on both the nodes..
I can able to connect from the server , but from any client it is giving this problem
Thanks
Kai

LOCAL_LISTENER is not supposed to be the listener name - it should be a tnsnames entry from the server's tnsnames.ora (in $ORACLE_HOME/network/admin). Or it can be an embedded connect string such as "(ADDRESS=(PROTOCOL = TCP)(HOST = 192.168.0.85)(PORT = 1521))".
Check that LOCAL_LISTENER is configured correctly with "lsnrctl services <LISTENER_NAME>" on your server - you should see the instance listed as accepting connections. If you don't see the instance then maybe you have an invalid TNSNAMES alias in LOCAL_LISTENER.

Can Oracle 11g RAC support 2 separate databases?

1. Can Oracle 11g RAC support 2 separate databases given that it asks for SCAN ip for cluster with a single Listener port number?
2. Will the Oracle 11.2 database connections work successfully if I setup a mandatory DNS server within the Oracle RAC servers?
I'm leading a team for a 11g project and appreciate responses.
Thanks
Satish.

No Real Application Cluster technology has ever supported more than one database.Quite untrue.
I know that both you and Tom Kyte take the stand that a cluster should have only 1 instance per node.
That doesn't mean that it is not possible to have more than one database in a cluster -- i.e more than one instance in a node.
That doesn't mean that it must always be so. Installing a separate cluster and additional EE + RAC licences for a separate database can be quite expensive. Of course, your reply is "consolidate". That is another debate that has been going on for years.
A discussion on multiple databases on RAC is also at

Theoretical question on having "stand by" instance on 4 node RAC cluster.

We have been having discussions on how we can improve the overall stability and performance of our RAC cluster. Currently we are running multiple databases on a 2 node cluster. The idea is that we will add two more nodes to the cluster and then spread the instances across the 4 nodes but only have two active and 1 as a standby in the event of node failure.
In other words:
Node1, Node2, and Node3 would run DB1
Node 4 Node3 and Node2 would run DB2
Additionally DB1_Instance3 would be shutdown on Node3 and only started if Node1 or 2 failed.
This would be the same for DB2 where DB2_Instance3 on Node2 would only be started if Node3 or Node4 failed.
Underneath them all would be the same ASM database shared for all 4 nodes.
Has anyone seen such a configuration? Is anyone aware of a white paper that discusses it.

the parameter active_instance_count is a 9i parameter and should only be set if you want to run RAC with a 2 node cluster - one instance active (all users connected here) and the second instance up but no one actively using it. IF instance one goes away, all work is move to instance 2. This is hot failover .
If you are adding a new instance to a rac database, you are recommended to use DBCA or EM to add the instance. If you do not want to have users connected to the instance all the time, you can either leave it running but do not enable any services on it until you need it or stop the instance with srvctl stop instance. The cluster will not try to restart the instance automatically.
The services option, when you create a service, you define which instances you wish it to run on. You can dynamically change where it runs. For the end user, they just connect to the service, the listener directs the connection to the least loaded instance providing the service at connect time. See the workload management with RAC 10g white paper on otn (otn.oracle.com/rac) or Chapter 6 of admin & deploy guide

Unable to create RFC iviews - connection test of the system failed

hello,
I always try to configure my system to run an RFC iView...
The connection of myt system is failed for 1 of the 4 tests.
i don't know why.
I have filled this fields :
- application host
- ITS host name
- ITS path
- ITS protocol
- Logical system name (not sure it's correct)
- Sap client
- Sap system ID
- SAP system number
- Server port (not sure it's correct)
- System type
- Web as host name
- Web as path
- Web as protocol
and i have this error :
SAP Web AS Connection
Test Details:
The test consists of the following steps:
1. Check the validity of the system ID in the system object
2. Check if the system can be retrieved
3. Check if a SAP system is defined in the system object
4. Validate the following parameters: WAS protocol; WAS host name
5. Check HTTP/S connectivity to the defined back-end application
Results
1. The system ID is valid
2. Retrieval of the system was successful
3. The system object represents an SAP system
4. The following parameters are valid: Web AS Protocol (http) Web AS Host Name (wsapv49.dhcp.xxx.xx.xxxx:8045)
5. HTTP/S connection successful
ITS Connection
Test Details:
The test consists of the following steps:
1. Check the validity of the system ID in the system object
2. Check if the system can be retrieved
3. Check if the system object has a valid system alias
4. Check if a SAP system is defined in the system object
5. Validate the following parameters: ITS protocol; ITS host name
6. Check the validity of any user mapping in the system object
7. Check HTTP/S connectivity to the defined back-end application
Results
1. The system ID is valid
2. Retrieval of the system was successful
3. Retrieval of the default alias was successful
4. The system object represents an SAP system
5. The following parameters are valid: ITS Protocol (http) ITS Host Name (wsapv49.dhcp.xxx.xx.xxxx:8045)
6. HTTP/S connection successful
Test Connection with Connector
Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the backend application using the connector defined in this system object
Results
Retrieval of default alias successful
Connection failed. Make sure user mapping is set correctly and all connection properties are correct.
Test Connection through the DQE
Test Details:
The test consists of the following steps:
1. Checks the existence of a backend admin user ID/password in the system properties.
2. Checks the existence of a default alias for the system.
3. Checks the DQE connection.
Results
1. DQE admin user ID or password is missing in the system properties. Make sure those properties exist for this system object.
2. Default alias of the system exists.
3. DQE connection successful. If you continue to experience problems, verify the DQE admin user ID and password properties for this system object.
can you help me to end this configuration?
thanks a lot.
(reward points for helful answers...)
