Accessing Oracle On VirtualBox From Host Virtual Machine?
Jul 18, 2013
I have a Host system of windows 8, installed the Virtual Box Latest edition.The guest OS is the oracle Linux that came with the Pre-Built Developer VMs from Oracle.The VM is set to HOST ONLY network setting. Now, the thing is that i want to access the Oracle in the guest machine from my windows host machine.the guest OS shows the IP address as 192.168.56.101. I can ping the IP address from the HOST machine, but cannot connect theSQL developer to the oracle in the guest OS from the host machine. It keeps on saying the Network adapter cannot connect. do not say that install the oracle in window itself. I actually want to do the same on my macbook pro as that is my primary machine.

How to get a RAC running in an EC2 environment?
It isn't possible to use one EC2 machine for each RAC node because EC2 can't handle the virtual IPs, but I had thought that I could use one EC2 machine to host several Linux VMs using Virtual Box (the same way that I use Virtual Box on a Windows host). But I can't get Virtual Box working on EC2. The only relevant advice I can find on this is comments to the effect that running any virtualization product with a Xen machine as host is not a good idea.
I do realize that this isn't a 100% Oracle question, but if set up a RAC on an Amazon Cloud machine,

SLES 11
Oracle® Enterprise Manager Grid Control Installation and Configuration Guide
10g Release 5 (10.2.0.5.0)
Part Number E10953-1518 Configuring Enterprise Manager for Active and Passive Environments18.1 Using Virtual Host Names for Active and Passive High Availability Environments in Enterprise Manager Database ControlSet Up the Alias for the Virtual Host Name and Virtual IP Address
You can set up the alias for the virtual host name and virtual IP address by either allowing the clusterware to set it up automatically or by setting it up manually before installation and startup of Oracle services. The virtual host name must be static and resolvable consistently on the network. All nodes participating in the setup must resolve the virtual IP address to the same host name. Standard TCP tools similar to nslookup and traceroute commands can be used to verify the set up.

I am having 3 oracle 10.2.0.5 version standard edition databases running on windows platform on 3 different servers. OEM is configured for all the 3 databases and we are able to access these OEM from their respective servers.
As per my knowledge, I should be able to access the OEMs of all 3 databases from my local machine. But Iam facing problem in accessing the OEMs from my local machine.
what changes need to be done so that I can access the OEMs of all 3 databases from one single local machine rather than checking it by logging into their respective servers.

I work as a Sys. Admin. for several RHEL 3.8 servers, most of them are clusters of 2 machines. All these servers are running Oracle 9.2.0.7 database. They are running fine on a separate filesystem. So everytime the system has to be formatted for some particular reason, there is no need to re-install the database.
I am trying to make some tests by running the same filesystem containing the oracle database in a fresh Red Hat Enterprise Linux 4.8 X86_64 Install. This task has become impossible, and I'm not quite sure why.
I installed all the compat- packages required for a fresh oracle 9 install in a RHEL4 machine, but at the time of stating the STARTUP sentence, it gives me the next error:
CMCLI ERROR: OpenCommPort: connect failed with error 2.
CMCLI ERROR: OpenCommPort: connect failed with error 2.
CMCLI ERROR: OpenCommPort: connect failed with error 2.
CMCLI ERROR: OpenCommPort: connect failed with error 2.
CMCLI ERROR: OpenCommPort: connect failed with error 2.
After this error (repeated) it says something like: Cannot start an already running database.... But if i stat a shutdown sentence, it says that the instance has not been initialized....
I don't know whether i have to re-install all the oracle software in order to make a clean install in the new kernel version or not, i tried to apply a patch, and the oracle installer recognized the installation i had.
I think it might be because the original system is configured to work as a cluster, and i'm running it on only a virtual machine.

Oracle 11g installation problem in Oracle VM VirtualBox (Linux)
I've attended the training on 11g admin i in my school and still confused about installation. My tutor asked me to copy the ".vdi" file from my school and import into my home pc for practice. He said in order to practice at home, have to do the following.
1. Grid Infrastructure
2. Oracle Software
3. Oracle Database
I already installed Oracle VM Virtual Box and imported the ".vdi" file (In Linux). Does this vdi file include all the 3 items above? My vdi file size about 30G. Currently, i can't access Enterprise management, dbconsole.

I have installed Oracle 11g R2 on Oracle Linux and Oracle Instant Client on Windows 7. I am trying to access the server from the Oracle client but I am getting the following error:
ORA-12560: TNS: protocol adapter error
I have set the below TNSNAMES.ORA file on the client machine and the LISTENER.ORA file on the server:
#TNSNAMES.ORA
OCCELLUS =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = oracle.localdomain)(PORT = 1521))
)
CONNECT_DATA =
[code]........
The ORACLE_SID is OCELLUS.
The host name is oracle.localdomain
Pinging between the client/server works fine. I have turned off the firewall on both the client (Windows firewall) the Server (IPtables) but got the same problem!
I have also set the ORACLE_HOME, TNS_ADMIN and PATH in the Windows environment variables.

We have been upgrading our servers to Server2008 and are getting..
[ORA-3134: Connections to this server version are no longer supported.]
..using the drivers we used to use in XP and Server2003 to access a legacy Oracle7 db. Connections to this db are needed for typical CRUD functionality by multiple applications, some written in Classic ASP and some in C# .NET 3.5 & 4.0. I have tried ODBC drivers (System.Data.Odbc) and also ODP (Oracle.DataAccess.Client) to no avail.
Any existing driver solution to make this connection without have to resort to a custom HLI interface?
I would think we aren't the only ones needing to access Oracle7 from Server2008.

We just got a new Dell R720 server that will host our Oracle DB. The server hasn't even been turned on yet but we know that the load on the server will be very low for a long time.
One of our problems is that we need to run a VERY important application. Since it is not very resource consuming compared to it's importance we chose to run it on a not so new Xeon 5110 1.60 GHz - 4GB RAM server. He said it's not a good idea and that we should buy a new server. (money is very low)
The software vendor suggested to virtualize our R720 server, host a vm running our database, and along with it other smaller machines like the one I described above. I suggested the use of Oracle VM, Oracle Linux for the database host and transforming the physical servers servers in VM with P2V.
Our IT Manager didn't like that, he said that it's not recommended to run a database on a virtual machine. But our software vendor said that many of their clients run their solution this way.

Host: Win7
Guest: Using Virtual PC on Win7, created a VM using XP-Mode. Installed Oracle and everything on it. I can connect to the Oracle from within the guest env using sqlplus. Listener is also running, checked with 'lsnrctl status"
Guest and Host can ping (network) each other. I installed the guest using the Microsoft Loopback Adapter. Disabled the firewall on the guest OS before the host ping could work.
So ping works both ways from guest to host and host to guest. tnsping from host fails says "no listener". When I did a "telnet 192.168.x.x 1521" from host it said could not open connection on port 1521.
How do you open port 1521 on the guest OS to traffic from the host OS?

When working against the Oracle 10G/11G RAC database it's important to have all the relevant entries in the etc/hosts file.
Thus, when running the following code against the database sometimes it finishes with "Ok!" and sometimes getting the error below:
CODEimport java.sql.*;
public class TestDBOracle {
public static void main(String[] args)
[Code].....
The reason is missing RAC-related entries in the etc/hosts.
When dealing with Oracle RAC it should be both entries for the public and for the virtual IPs of the nodes in the etc/hosts file.
CODEA.A.A.A NODEA
A.A.A.B NODEB
...
B.B.B.X NODEA-VIP
B.B.B.Y NODEB-VIP
