Number of ssh connection to Oracle servers

Hello All,
one of the requirements while implementing Oracle rac is to have passwordless ssh connectivity betweeen the nodes.
My question is that needed after implementation by the Oracle nodes?
Does Oracle nodes communicate to each others using ssh after implementation?
Regards,

OK, a quick search yielded this Oracle document
http://www.oracle.com/technetwork/articles/hunter-rac11gr2-iscsi-2-088698.html
16. Configure RAC Nodes for Remote Access using SSH - (Optional)
Perform the following optional procedures on both Oracle RAC nodes to manually configure passwordless SSH connectivity between the two cluster member nodes as the "grid" and "oracle" user.
One of the best parts about this section of the document is that it is completely optional! That's not to say configuring Secure Shell (SSH) connectivity between the Oracle RAC nodes is not necessary. To the contrary, the Oracle Universal Installer (OUI) uses the secure shell tools ssh and scp commands during installation to run remote commands on and copy files to the other cluster nodes. During the Oracle software installations, SSH must be configured so that these commands do not prompt for a password. The ability to run SSH commands without being prompted for a password is sometimes referred to as user equivalence.
The reason this section of the document is optional is that the OUI interface in 11g release 2 includes a new feature that can automatically configure SSH during the actual install phase of the Oracle software for the user account running the installation. The automatic configuration performed by OUI creates passwordless SSH connectivity between all cluster member nodes. Oracle recommends that you use the automatic procedure whenever possible.

How to find the number of ODBC connections to Oracle Database

Hi All,
How to find the number of ODBC connections and all connections to the Database in last week. Are there any views to get this information?
Thanks in advance,
Mahi

What Ed said is true that Oracle doesn't note which type of protocol is connecting to the database, however, you can see which program is accessing the database.
For example: if you already know of a user using ODBC, you can verify as:
select username, osuser, terminal, program from v$session where username = 'SCOTT'
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Assuming that you can confirm the progam noted in the above (example) is the one using ODBC, then you can change the query such as:
SQL> select username, osuser, terminal, program from v$session where program = 'w3wp.exe';
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Just for kicks, I checked our listener.log file, but there was no reference of odbc in it either.
Hope this helps...

What limits the number of MII connections to Oracle.

We are using MII 12.0.5 and an Oracle database and are seeing errors in the logs to the effect:
SQL error occurred on connection jdbc:oracle:thin:@mii001:1527:SMD: code=0, state="null", message="Listener refused the connection with the following error:
ORA-12518, TNS:listener could not hand off client connection
The Connection descriptor used by the client was:
mii001:1527:SMD
I am ot an Oracle expert and I have not seen this issue before. What is limiting the number of connections? Is this a MII configuration issue that I am not aware of or an Oracle database issue?

Hello sparks,
I assume you are getting this error when you are trying to connect to databse while configuring Dataservers in MII,if fo what are the value you passed in the fields PoolMax and PoolSize while connecting to the database.

Kumar

Connecting to Oracle servers using dialup

Hi,
I am trying to connect to the Oracle databases at work from home. I have Oracle Client (8.1.7) loaded on my PC and the tnsnames.ora and sqlnet.ora are exactly the same as the ones on my PC at work. When I connect via dialup to work, it allows my PC to be a node on their network. But I can't access any of our Oracle servers, the message is host not found. Cannot ping to the servers either.
Does anyone know what else I need to configure this to work?
Thanks.

Just to take a quick step back, are you using some sort of VPN software once you've dialed up that allows you to bypass your company's firewall? Oracle databases generally are not and should not be made available through company firewalls. Can you connect to work-related machines other than databases (file servers, etc) when you dial in from home?

Huge number of idle connections from loopback ip on oracle RAC node

Hi,
We have a 2node 11gR2(11.2.0.3) oracle RAC node. We are seeing huge number of idle connection(more than 5000 in each node) on both the nodes and increasing day by day. All the idle connections are from VIP and loopback address(127.0.0.1.47971 )
netstat -an |grep -i idle|more
127.0.0.1.47971 Idle
any insight will be helpful.
The server is suffering memory issues occasionally (once in a month).
ORA-27300: OS system dependent operation:fork failed with status: 11
ORA-27301: OS failure message: Resource temporarily unavailable
Thanks

Ssh connectivity(password less) for oracle unix account in 11gR2 RAC

DB : 11.2.0.2
OS : Unix
While installiation of RAC, password less connectivity setup is required between two nodes to copying files and to run commands. This is mandatory before installation.
But after installation, is it require to have password less connectivity ( SSH) between two nodes ? By locking "oracle" unix account breaks ssh connectivity between two nodes. Even though it's not breaking cluster, but do we really need ssh connectivity once RAC db is up and running ?

it is also used when you apply patches but not for everyday 'normal' operation
http://download.oracle.com/docs/cd/B19306_01/install.102/b14203/prelinux.htm#BABJBAEB
Oracle Universal Installer uses the ssh and scp commands during installation to run remote commands on and copy files to the other cluster nodes. You must configure SSH so that these commands do not prompt for a password.

How to connect to oracle ebs from an external software

Hi!
I want to develop an integration for oracle EBS. Therefor I'm looking for ways how to connect to the EBS and for a repository of functions which can be called from an external program. I'm not quite sure if this is the right place to ask but I could not find anything yet so I'm trying here.
Are there any standard connectors for the EBS provided by Oracle?
Thanks,
Konrad

Oracle Applications Architecture is a framework for multi-tiered, distributed computing that supports Oracle Applications products. In this model, various servers are distributed among multiple levels/tiers as follows:
- The Desktop Tier --> Web browser with Jinitiator or Sun JRE
- The Application Tier --> Web, Forms, Reports, Admin, and Concurrent servers
- The Database Tier --> Oracle Enterprise Edition Database
The Application tier is the layer which is responsible for:
- Hosting the various servers that process the business logic
- Managing communication between the desktop tier and the database tier
So, in order to connect to the database, you can either access the application tier, or connect directly to the database. I do not think it is possible to communicate with the application services from some other application. Therefore, you would need to connect to the database directly which can be achieved as explained in my previous reply. There is no such API which can be used to open/close a database connection. Oracle E-Business Suite is just a database with number of schemas and objects which are tightly integrated.
More details about Oracle E-Business Architecture can be found in:

I have a Dell Power Edge Server with 1 network card. I have installed VMWare ESXi 5 on it. Created several Windows 2003 Servers Virtual Machines. Networking is working fine all these windows machines. On one of the virtual machines I have installed Oracel VM Server 2.2.2 (Dom0) and on top of it I am trying to install Oracle VM Template for Oracle 11g provided by Oracle. I am having connectivity issues on the Oracle 11gDB (DomU). I can ping and ssh from Dom0 to DomU and vice versa. But I cannot connect the Oracle DB machine from any other machine. I can connect the Oracle VM Server (Dom0) from other computers in my network.
Any clue what the issue is ?
Thanks,
Ruchin

How to find the number of users connected to database from OS level(Linux)

Hi All,
Could anyone know , how to find the number of users connected to database without connecting with sql*plus
is there any command to find it?
example we have 10 databases in one server, how to find the number of users connected to particular database without connecting to database(v$session)?
oracle version:- 10g,11g
Operating System:- OEL4/OEL5/AIX/Solaris
any help will be appreciated.
Thanks in advance.
Thank you.
Regards,
Rajesh.

Excellent.
Tested, works as long as you set the ORACLE_SID first ( to change databases )
ps -ef | grep $ORACLE_SID | grep "LOCAL=NO" | awk '{print $2}' | wc -l
Thanks!
select OSUSER
from V$SESSION
where AUDSID = SYS_CONTEXT('userenv','sessionid')
and rownum=1;Best Regards

Not able to connect remote oracle database over VPN

I can not connect remote oracle database over VPN. tnsping is ok and it shows the server information of remote database. i can also telnet the 1521 port of remote database server. I can connect the same server when it is located in the same LAN. Please help me out this is very urgent.

First, this is a forum of volunteers. There is no "urgent" here.
"Urgent" means one of two things -
1) people are dying, or
2) you have a customer-facing, revenue-producing production system that is down.
(And to get some perspective on the second case, keep the first in mind.)
For the first, you call whatever civil emergency service seems appropriate.
For the second, you open an SR with Oracle - which requires a paid-up support contract. For *them* to consider your problem "urgent", you will need to demonstrate that your problem falls under item #2. I seriously doubt your problem fits that criteria.
You don't have a support contract? Now you know the exact dollar figure that your company places on the data.
That said, you need to understand a few things about your specific problem,
First, port 1521 is only used by the listener to accept a connection request. Once it gets that request (and finds that it is for a service (sid) that it knows about, it will fork a server process and tell the requesting client that it can communicate with that server process over some other port .. a randomly chosen port number in the "high" range. It could be your vpn is blocking that other port, whereas your internal firewall is not.
But this is just an educated guess since I cannot find "can not connect remote oracle database over VPN" in any error message manual. If you had mentioned the VPN along with an actual oracle error message we could be much more precise in our diagnoses and recommendations.
---- edit 22 Sep
It occurred to me that I just assumed you were using the same client machine in both cases ... a laptop that you use both at work (local network) and home (vpn). If that assumption is false, there are probably problems with your tns setup on the home (vpn) machine.
But again, it would be much easier to help if you gave us an actual error message.

Can't get Microsoft FrontPage to connect to Oracle 9.2i

After considerble discussion in the microsoft.public.frontpage.client newsgroup (subject: "Database | Results ... won't ... through Oracle ODBC"), we had to give up and conclude that there didn't seem to be a straightforward way to connect to Oracle 9.2i via the FrontPage database wizard.
I tried a system Oracle ODBC DSN via MS Access and it worked; but, ` can't get the same DSN to work from FrontPage. From FrontPage it generates a user/password error, though the same user/password works from MS Access.
I tried an OLEDB connection and still received the following:
Server error: Unable to connect to a database from the web server using the
connection string 'Provider=MSDAORA; PWD=myPwd; UID=Administrator; Data
Source=glOdb.mikecoughlin.net'.
The following error message comes from the database driver software; it may
appear in a different language depending on how the driver is configured.
ORA-01017: invalid username/password; logon denied
Source: Microsoft OLE DB Provider for Oracle
Number: -2147217843 (0x80040e4d)
I'm certain that this user/password combination is valid e.g. it works in Enterprise Manager to view tables etc.
So, my question is:
Does anyone have a/the workaround to use FrontPage to connect to Oracle 9.2i ?
thanks,

JDBC connection to Oracle 10g RAC periodically times out

I've been banging my head against the wall for months now and can't figure out why this is and what's causing it.
We have 6x CF8 servers in our environment. 3 of which work perfectly and the other 3 have the following problem. All 6 machines were installed at the same time and followed the exact same installation plan.
When I configure Oracle RAC data source, some of the machines time-out connecting to Oracle from time-to-time.
Config:
Solaris 9 on both CF and Oracle
CF8 Enterprise with the latest updater.
Apache 2 (not that it's relevant)
6 machines, load-balanced (not clustered), identical install and configuration.
data source config:
JDBC URL: jdbc:macromedia:oracle://10.0.0.3:1521;serviceName=dbname.ourdomain.com;AlternateServers= (10.0.0.4:1521);LoadBalancing=true
DRIVER CLASS: macromedia.jdbc.MacromediaDriver
The problem:
Every few minutes, CF starts hanging requests that deal with a specific RAC only data source. After about 30 seconds, all requests bail and generate this error in cfserver.log:
A non-SQL error occurred while requesting a connection from dbsource.
Timed out trying to establish connection
This happens with any RAC data source on the "bad" servers while the "good" servers don't have this problem. The "bad" server doesn't have any problems with direct (non-rac) Oracle data source.
Already tried:
Moving server connections around on a switch (rulling out bad switch port)
Copying driver from the healthy server (but it's the same installer anyway)
Changed from RAC to normal Oracle type data source - works perfectly. So at the moment I have 3 servers connecting to a specific oracle instance and the other 3 connecting to RAC.
Tried googling and searching forums and even Oracle metalink - nothing I could see relevant to this.
It's a shame that after spending a ton of money on CF8 upgrades and Oracle RAC, we can't really utilize fail-over on the database connection.
Any takers?
Thanks,
Henry

How can I connect to Oracle and SQL server at the same time?

I have been trying to find a way to connect to Oracle Database through the developer 2000 and SQL server at the same time. I need to return some data from Oracle Database and some from the Sql Server Database. And update both through SQL. I find there is such a thing as the Oracle Transparent Gateway for SQL server. I can't find it on any of my CD's or through OTN downloadable files. If anyone can point me where to get this. Or tell of another way this can be accomplished I would appreciate it. TIA.

As far as I know you have 3 options depending on your specifications. I don't think option #3 will work if you need to actually join a
SQL Server table to an Oracle table.
1. Oracle Transparent Gateway. I haven't used the Oracle Transparent Gateway but my understanding is that Oracle gateways are
separate purchased products from Oracle. I've never seen any free/development versions of it anywhere. You'll need to contact
your Oracle sales rep about it.
2. Heterogeneous Connectivity. There's something called Heterogeneous Connectivity that could work for you - depends on what
version of Oracle you're on and what OS. You basically set up an ODBC data source on the Oracle server and modify the listener.ora
and tnsnames.ora files. You can then create a database link to SQL Server just like you would to any other Oracle database. You can
check your Oracle documentation for how this works. There's also some very good documents on Metalink that tell you how to do this
as well as a Heterogeneous Connectivity forum on this site.
3. Use the exec_sql package available in Developer 2000. This allows you to open and execute cursors to remote databases within
Developer. We have an account validation process that uses this - when a person enters an account number in a form while logged
into Oracle it validates the account is valid in our main accounting DB2 database. We also pull HR information from DB2 into Oracle
this way. If you're using Forms 6i exec_sql is a built-in command, in Forms 5.0 and 5.5 you have to add it as an attached library to
the form. I think you also need the OCA options installed from the Developer software to have access to the library in Forms 5.0 and
5.5. The library will be in the $ORACLE_HOME\oca20\plsqllib directory for these versions. The Developer documentation should have
additional information.
