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.
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,
In my Organization I am trying to install oracle ODTwithODAC112030 but one Error showing that is java virtual machine could not find main class program will Exit.

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.
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 am trying to install Oracle RAC installation w/ guest OS OracleLinux6 on Virtualbox/Mac OS.But getting problem to set network & ip setting and yum is not able to reach oracle repository.
if anyone tried installing Oracle RAC installation w/ guest OS OracleLinux6 on Virtualbox on intel based Mac OS.
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:
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 have a scenario where Oracle Database R1 is installed on Windows System and the Client is present on Linux. Both the system is on same network. We can access Windows -2-Windows using TNS entry.
I am unable to connect to this scenario where Database is on Windows and Client is on Linux.
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.
I am configuring two node RAC on oracle virtual box. Did its mandatory to configure DNS on both nodes before Rac installation? Whats the purpose of DNS in RAC. And if its mandatory did i have to configure DNS on each node separately?
I have a requirement wherein I need to access the MS ACCESS database table from Oracle Client.I have created ODBC data source and have configured tnsnames.ora and listener.ora for the same. As a next step I am trying to configure HS init file for hsodbc connection but couldn't find the directory hs in $ORACLE_HOME (<ORACLE_HOME>hsadmininit******.ora). Any patch that needs to be applied for hsodbc connection in the server.
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?
I am having issue with IMPDP on ORACLE VIRTUAL COLUMNS.I am having following table with Virtual column defined with Not null. Expdp is fine without any issue.
DDL : ------ CREATE TABLE alert_hist ( alertky INTEGER NOT NULL, alertcreatedttm TIMESTAMP(6) DEFAULT systimestamp NOT NULL, alertcreatedt DATE GENERATED ALWAYS AS (To_date(Trunc("alertcreatedttm"))) VIRTUAL NOT NULL
When I do the import (IMPDP) it got failed with the following error.
. . imported "TESTSCHEMA"."VALART" 359.1 KB 4536 rows ORA-31693: Table data object "TESTSCHEMA"."ALERT_HIST" failed to load/unload and is being skipped due to error: ORA-39097: Data Pump job encountered unexpected error -1
After that I dropped the Virtual Not null column and recreated that column with Nullable.
DDL : ----- alter table alert_hist drop column alertcreatedt; alter table alert_hist add alertcreatedt DATE GENERATED ALWAYS AS (To_date(Trunc("alertcreatedttm"))) VIRTUAL;
After that I took the expdp and impdp , it went fine with out any issue.
DB: 11.2.0.3 & OS: RHEL5 Easy Connect Naming method enhances the host naming method by allowing for a port and service specification. My question is does Oracle 11g support Host naming method?
I installed Oracle 11g Express edition in my local Machine(Windows 7).listener.ora, tnsnames.ora files seems fine. Service and listener are running; While trying to connect to the my db sqlplus>connect sys/oracle as sysdba
I am getting "ora - 12543 TNS: destination host unreachable."
what could be the issue. Find below listener.ora, sqlnet.ora, tnsnames.ora files:=
What tool can be used to monitor Oracle host on Windows environment if the database goes down? I know about "Nagios" but like to know is there any other tool available?
