I just Installed Oracle Database 12c. At the end of the installation it gave me Information about my connection. SID, IP, etc. I restarted the computer run all these services (some of them already running):
OracleJobSchedulerORCL
OracleOraDB12Home1MTSRecoveryService
OracleOraDB12Home1TNSListener
OracleRemExecServiceV2
OracleServiceORCL
OracleVssWriterORCL
But I think I forgot the IP and port of my database since I tried to access the database using a webbrowser and it doesn't work (I tried https://10.10.10.10:5500/em). I don't know If the problem is really the IP:Port that I may have forgotten or if I forgot to run service. I am pretty sure the IP address look like https://10.10.x.x:xxxx/em but I don't I am not certain. Is there a way to recover the IP address and port of the database?
EDIT: I've installed it on Windows 8 x64 JP. with
In Environment Variable
with ORACLE_HOSTNAME = 10.10.10.10
ORACLE_UNQNAME = orcl
And in the host file (in System32/Drivers/etc/)
127.0.0.1 localhost
10.10.10.10 wopr.orcl wopr
Per documentation, format for accessing enterprise manager in your browser
http://hostname:portnumber/em
Once you sure that default port number is kept as default HTTP port number is 5500 then you can get your system hostname. Port numbers are recorded in $ORACLE_HOME/install/portlist.ini file.
If running windows then just run the command hostname which will give you the hostname of your machine. Then run like
http://My_hostname:5500/em
Or use the command ipconfig to see your IPV4 address and use that address
http://X.X.X.X:5500/em
Or you as well use localhost
http://localhost:5500/em
or 127.0.0.1 (loop back address) like
http://127.0.0.1:5500/em
See here for more information
Well, if you installed it on your local machine, you can always access it using localhost, so try https://localhost:5500/em.
The default port number for Enterprise Manager is indeed 5500.

I have a windows server 2016 machine which I have Jenkins running on. I wanted to install SonarQube. So have downloaded v7.1
I have managed to start sonarqube on the machine and can view the webserver at http://localhost:9000
I tried to view the page on a different machine using the IP address and port 9000, but this doesn't connect. Looking in the sonar.properties file I can see
Binding IP address. For servers with more than one IP address, this property specifies which
address will be used for listening on the specified ports.
By default, ports will be used on all IP addresses associated with the server. sonar.web.host=http://xx.xxx.xxxx.xxx
If I use http:// then sonarqube starts, but I can't see sonarqube from any other machine, if I don't use http:// (so just the ip) then it won't start with a bind error.
Has anyone experience of setting this up on windows?
Turns out it was something a lot simpler, the machine is being run on azure and there was no port 9000 endpoint
I've got a RMI server running on a mac. Once I changed the server IP and restart the Application and clients, then clients keep connect to the old ip address with right bind and lookup address. I really have no idea what went wrong because the program is working on another linux server just with different port.
What the remote object clients got is Proxy[MinervaInterface,RemoteObjectInvocationHandler[UnicastRef [liveRef: [endpoint:[192.168.0.104:51815](remote),objID:[40d99efb:140ba232cec:-7fff, 6333954213550330995]]]]]
which 192.168.0.104 is the old IP and it should be 10.0.1.104
I've check the host file and my code, there is no anything like 192.168.0.*
Please help, Thank you.
UPDATE
I have confirmed this is a server registry problem. But I have already restarted the server. I did't remember what else did I do to the registry. Is there any way to set it manually?
UPDATE
I rune this code on that server InetAddress.getLocalHost().getHostAddress(), it returned 192.168.0.104, that can explain where this address came from. But there is no such address on the server now
SOLVED
I found java use a hostname to lookup localhost address, that hostname is not localhost and have not been updated by OS X Server for some reason. I updated the record from OS X Server console and solved this annoying problem.
NEVER THOUGHT ABOUT THAT
I developed a client/server simulation application. I deployed client and server on two different Windows XP machines. Somehow, the client is not able to send requests to the server.
I tried below options:
Pinged server machine successfully from client using ip-address.
Pinged client machine successfully from server using ip-address.
Checked netstat command line tool from both machines. Server is in LISTENING mode and client is in SYS_SENT mode. But the foreign address it is using to send is host name not the ip address.
Pinged server machine unsuccessfully using host name from client.
Pinged client machine successfully using host name from server.
I feel the problem is when the client is trying to connect to the server using the host name.
Could you please let me know how to force an application to use an ip address instead of a host name? Is there any other way to map the host name to an ip address?
Go to your client machine and type in:
nslookup server.company.com
substituting the real host name of your server for server.company.com, of course.
That should tell you which DNS server your client is using (if any) and what it thinks the problem is with the name.
To force an application to use an IP address, generally you just configure it to use the IP address instead of a host name. If the host name is hard-coded, or the application insists on using a host name in preference to an IP address (as one of your other comments seems to indicate), then you're probably out of luck there.
However, you can change the way that most machine resolve the host names, such as with /etc/resolv.conf and /etc/hosts on UNIXy systems and a local hosts file on Windows-y systems.
Try tracert to resolve the hostname. IE you have Ip address 8.8.8.8 so you would use; tracert 8.8.8.8
You could use a C function getaddrinfo() to get the numerical address - both ipv4 and ipv6.
See the example code here
This is hard to answer without more detail about the network architecture. Some things to investigate are:
Is it possible that client and/or server is behind a NAT device, a firewall, or similar?
Is any of the IP addresses involved a "local" address, like 192.168.x.y or 10.x.y.z?
What are the host names, are they "real" DNS:able names or something more local and/or Windows-specific?
How does the client look up the server? There must be a place in code or config data that holds the host name, simply try using the IP there instead if you want to avoid the lookup.
Windows XP has the Windows Firewall which can interfere with network traffic if not configured properly. You can turn off the Windows Firewall, if you have administrator privileges, by accessing the Windows Firewall applet through the Control Panel. If your application works with the Windows Firewall turned off then the problem is probably due to the settings of the firewall.
We have an application which runs on multiple PCs communicating using UDP/IP and we have been doing experiments so that the application can run on a PC with a user who does not have administrator privileges. In order for our application to communicate between multiple PCs we have had to use an administrator account to modify the Windows Firewall settings.
In our application, one PC is designated as the server and the others are clients in a server/client group and there may be several groups on the same subnet.
The first change was to use the functionality of the Exceptions tab of the Windows Firewall applet to create an exception for the port that we use for communication.
We are using host name lookup so that the clients can locate their assigned server by using the computer name which is composed of a mnemonic prefix with a dash followed by an assigned terminal number (for instance SERVER100-1). This allows several servers with their assigned clients to coexist on the same subnet. The client uses its prefix to generate the computer name for the assigned server and to then use host name lookup to discover the IP address of the assigned server.
What we found is that the host name lookup using the computer name (assigned through the Computer Name tab of the System Properties dialog) would not work unless the server PC's Windows Firewall had the File and Printer Sharing Service port enabled.
So we had to make two changes: (1) setup an exception for the port we used for communication and (2) enable File and Printer Service in the Exceptions tab to allow for the host name lookup.

I have installed Oracle 11gR2 on my machine, now when i try to connect to it using IP address as 'localhost' or '127.0.0.1' there is no issue, but when I use ip address of machine '192.168.1.6' it throws exception: Io exception: Then Network Adapter could not establish the connection.
I have installed ms loopback adapter prior to installation and my machine get IP from DHCP.
do i need to configure any setting oracle config or what i might be missing here?
Before looking at the network you need to check what address your listener is actually configured for. If it's specifying localhost or 127.0.0.1 then you won't be able to access remotely. If it's specifying a different IP previously allocated by DHCP then your current one won't work. If it's a host name, is that resolvable to your DHCP address?
As well as looking at listener.ora, you can try running netstat -an | find "1521" to see what address(es) it's actually listening on.
It's a network issue. Likely a firewall, router or proxy somewhere in the line isn't properly configured to forward the desired port.
Not a programming problem.
localhost and 127.0.0.1 are known to be the local machine. It can bypass a lot of the fluff.
When you try for 192.168.1.6, it will go and 'ask' a router (or similar) to send the traffic to that IP address. First I'd try to PING the IP address. If that works, I'd try telnet 10.253.82.33 1521 to see if you can connect to the port without involving JDBC or SQL or anything.
What steps do I need to take to change an IP address for Oracle 10g? I cannot connect to the database after going from a dhcp address to a static IP and a reboot.
If the server's IP address changed, these are the first things I would look at:
The TNSNAMES.ORA file on the client -- does it have the IP address hardcoded? If so, change it. Does it use the machine name? If so, does the machine name resolve to the correct IP address on your client machine?
The LISTENER.ORA file on the server -- does it explicitly specify the old IP address as its listening address?
More info please. Do you mean that you have changed the ip address of the host that the database is on and now you have to connect to it from a different macine, or are you having trouble starting the database after the ip change?
... and what error message do you receive?
Most obvious files to check are:
$ORACLE_HOME/network/admin/tnsnames.ora
$ORACLE_HOME/network/admin/listener.ora
Other than that we'd need more info...
I presume you mean the Oracle 10g DB and not the Oracle 10g Application Server?
Does the database start ok?
Is there anything in the database alert log?
Are the error(s) connecting from a client or the server?
What error message(s) do you get?
Can you ping the machine on it's new address (by both name + IP address) From both client + server?
Does a TNSPING work?
Can you connect using SQL*Plus on the server?
What other tool(s) have you tried connecting with?
Update after comment
Please can you post...
Your old ip address (if you know it)
Your new ip address
Your FQDN (e.g. machine.domain.com)
The output of "ipconfig/all" (or equivalent)
Your listener.ora file
The output of "$ORACLE_HOME/bin/lsnrctl start"
The output of "$ORACLE_HOME/bin/lsnrctl status"
Check that LOCAL_LISTENER is not defined (or defined correctly) in the database - it may not be registering correctly because of an incorrect entry here. Also try 'ALTER SYSTEM REGISTER' to attempt to register with the listener (rather than waiting up to 3 minutes for an auto-register). Examine the listener.log to see the instance registered (service_update * ) and 'lsnrctl status' to see if it is there.
Did you change the hostname in DNS? Can you ping the hostname from another machine?
