DBConsole Port Assignments by DBCA
We are using dbca to install several training instances on a server. This server has been used in the past as a database machine with DBConsole running on it. When DBCA creates the database the port for Database Control is set and seems to increment based on the old databases.
Is there a way to set this and not let the DBCA auto-increment the setting? Or where can I find where it is pulling the last port used so I can reset that?
On a Windows system, check the Registry settings under HKLM_Software. Oracle sometimes does not clean up the registry settings the way you expect.
The other possibility is in the inventory data kept at c:\program files\oracle.
If you are doing an uninstall and reinstall of the system, you can manually dump all the Oracle registry keys after the uninstall and physically delete the directory on the C drive, then perform the install.
I don't have the equivalent information for a UNIX system.

hi all. if my question can be answered by reading TMG documentation, feel free to direct me there (i tried searching for the admin documentation but couldn't find it).
can someone tell me what the purpose of dynamic port assignment is from endpoint -> TMG? Once the traffic leaves the TMG -> Internet, the actual service port is being used but that doesn't help me for internal queries.
many thanks,
-PHi,

Notes
This port is not used with ISA 2000.
FWC application transport and protocols are negotiated within the FWC control channel.
ISA 2000 FWC control uses UDP. ISA 2004 and 2006 use TCP.
OEM uses Firewall Web Management to provide non-MMC management of ISA Server.
This port is also used for intra-array traffic.
This port is used only by the ISA management MMC during remote server and service status monitoring.
This is the range in TMG. Please note that TMG extends the default dynamic port ranges in Windows Server 2008 R2, Windows 7, Windows Server 2008, and Windows Vista.

Hello
We have several 4404 controllers that each support 100 antennas.
When I follow the documentation for using multiple ap-manager interfaces (our controllers have 2 fibers to one switch and 2 to another one) it says that I have to create 3 additional ap-manager interfaces so that I can support 100 antennas.
So I did it.
The first problem I ran into is that I cannot assign backup ports to my ap-manager interfaces.
I get the following error:
"Backup Port cannot be configured for the ap-manager interface."
Is it because they are all on the same VLAN? So you cannot have two interfaces with the same vlan-tag on one physical port?
But then again in the documentation it says thatall the ap-managers should be on the same vlan/subnet.
Will it be possible in the future to have a tertiary and quadriary port assignment for dynamic interfaces? Because now when two fibers break I have the chance to loose an entire SSID.Port redundancy for the AP-manager interface is not supported. You cannot map the AP-manager interface to a backup port.

How to force the "Bluetooth Communications Port" to be one of COM1 to COM8 ports?
Dear Lenovo Community, Happy Holidays to you all and wish you a great happy new year. Recently purchased a Bluetooth OBDII device and have difficulty making it to work with its provided software on my T61 (running original XP Home). My short story and question/problem is that I can open "My Bluetooth Places" and pair with the OBDII device as an "OBDII SPP Dev", but my T61 assigns serial port COM19 to it. The OBDII software which came with the device only can let user set to one of the COM1 to COM8 ports and in the properties of Bluetooth pairing, there is no way that I can select which COM port to use. I looked at the Device Manager and I do see these COM port assignments: COM4,5,6,7: Sierra Wireless (the HSDA modem in the laptop which I have never used BTW) COM 9,10,11,12,13,14,15,16,17: Bluetooth Serial Port COM 18, 19: Bluetooth Communications Port and I don't see anything for COM1,2,3, and 8 My question is how to force the computer/OS to assign one of the COM1 to COM8 ports to my device upon pairing? Can I disable the Sierra Wireless model from the COM ports list and hope this will happen? Thanks for your help and inputs beforehand. Regards, AL
Hi, AL_K
Have you attempted to change the port number in device manager itself? If you navigate to Device Manager and open the list of Ports, you can right-click on the device you wish to assign a different port number. After right-clicking, click Properties. There should be a tab called Port Settings. In here, you should find a setting to manually assign a port number.
Good luck, and let me know how it goes,
Adam

How do I change a port in Mac OS X Mountain lion
Apparently Logmein makes use of port 2002 in mac OS X Mountain Lion. I need to use that for some new accounting software. How do I change the part in Mountain Lion and how would I do an install of Logmein on the computer to use another port or how, with Logmein currently installed do I change from port 2002 to some other port. The major question is how do you change port assignments in OS x Mountain Lion?
Thanks for you help.
Tom in DallasThere isn't a generic way to do what you want. Not on Microsoft Windows. Not on OS X.
The ICANN registry of port numbers exists so that these messes don't happen, or don't happen very often. So that there are no port conflicts among various applications, and there are ways to request ephemeral (temporary) ports, and (for some applications) to find out which port(s) the application happens to have allocated and is using. In this case, it appears that folks at LogMeIn and with the accounting software didn't avail themselves of the ICANN port database. They're using the preferences mechanism as a work-around for that.
Have a look at ipfw and pfctl tools here (see man ipfw and man pfctl at the Terminal.app prompt), and see if you can figure out how you're going to map just one local application that's opening 2002 to some other port, without disturbing the other application that's mapping to that same port (and colliding). This is the remapping mechanism and akin to what can happen at some firewalls, and not the requested control over the selected port. It's not set up to remap local application conflicts.
The selected port is either a configuration option within the specific tool, or it's hard-coded within the tool. There's no generic registry of applications and ports. That's what the ICANN port registry is for.
The worst-bad-ugly approach is to dump out the executable code, reverse engineer it, and patch the preferred port right into the code; to change the code without using the original source code. Or some tool-specific configuration file or preferences setting, as and if available. -
100% CPU Usage Overhead running EM DBConsole 11g on OEL-5.2
After upgrading to OEL-5.2 and relinking all Oracle binaries, my old Oracle 11g installation, installed several months before on OEL-5.1, has been working well, including Enterprise Manager Database Console working nicely as always with respectful performance. Unfortunatelly, it lasted just several days.
Yesterday I decided to uninstall the 11g completely and perform new clean installation (software and database) with the same configuration options and settings as before, including EM dbconsole, all configured using dbca. After completing the installation (EM was started automatically by dbca), oracle continued to suck 80-85% CPU time. In further few minutes CPU utilization raised up to 99% due to only one (always the same PID) client process - "oracleorcl (LOCAL=NO)". For first ten minutes I didn't care too much since I always enable Automatic Management in dbca. But after two hours, I started to worry. The process was still running, consuming sustained 99% of CPU power. No other system activity, no database activity, no disks activity at all!
I was really puzzled since I installed and reinstalled the 11g at least 20 times on OEL-5.0 and 5.1, experimenting with ASM, raw devices, loopback devices and various combinations of installation options, but never experienced such a behaviour. It took me 3 minutes to log in to EM dbconsole as it was almost unusable performing too slow. After three hours CPU temperature was nearly 60 degrees celsius. I decided to shutdown EM and after that everything became quiet. Oracle was running normally. Started EM again, the problem was back again. Tracing enabled, it filled a 350 MB trace file in just 20 minutes. Reinstalling the software and database once again didn't help. Whenever EM is up, the CPU usage overhead of 99% persists.
Here is a cca 23 minutes session summary report taken from EM dbconsole's Performance page. The trace file is too big to list it here, but it shows the same.

----------------------------------------Wow!!! Note: no disk, no database activity !
Has anyone experienced this or similar behaviour after clean 11g installation on OEL-5.2? If not, anyone has a clue what the hell is going on?
Thanks in advance.Hi Tommy,
I didn't want to experiment further with already working OEL-5.2, oracle and dbconsole on this machine, specially not after googling the problem and finding out that I am not alone in this world. There are another two threads on OTN forums (Database General) showing the same problem even on 2GB machines:
DBConsole easting a CPU
11g stuck. 50-100% CPU after fresh install
So, I took another, a smaller free machine I've got at home (1GB RAM, 2.2MHz Pentium4, three 80GB disks), on which I used to experiment with new releases of software (this is the machine on which I installed 11g for the first time when it was released on OEL-5.0, and I can recall that everything was OK with EM). This is what I did:
1. I installed OEL-5.0 on the machine, adjusted linux and kernel parameters, and performed full 11g installation. Database and EM dbconsole worked nice with acceptable performance. Without activity in the database, %CPU = zero !!! The whole system was perfectly quiet.
2. Since everything was OK, I shutdown EM and oracle, and performed the full upgrade to OEL-5.2. When the upgrade finished, restarted the system, relinked all oracle binaries, and started oracle and EM dbconsole. Both worked perfectly again, just as before the upgrade. I repeated restarting the database and dbconsole several times, always with the same result - it really rocks. Without database activity, %CPU = zero%.
3. Using dbca, I dropped the database and created the new one with the same configuration options. Wow! I'm again in trouble. A half an hour after the creation of the database, %CPU raised up to 99%. That's it.
The crucial question here is: what is that in OEL-5.2, not existing in the 5.0, that causes dbca/em scripts to be embarrassed at the time of EM agent configuration?
Here are the outputs you required picked 30 minutes after starting the database and EM dbconsole (sustained 99% CPU utilization). Note that this is just a 1GB machine.

SOAP receiver adapter - SOAP request over HTTPS to ther port than 443?
Hi guys!
Is it possible to send SOAP request from XI to target web service over HTTPS to other target port than 443? Our 3rd party web service is running other port..
Thanx a lot, OlianHi Olian,
Check out this,
http://www.grc.com/port_443.htm
http://en.wikipedia.org/wiki/HTTPS
The port 443 is just the default port. One can theoretically run protocols over any port. Port assignments are just suggestions to the world as to what to expect on certain ports

Installation of Oracle 10g Application Server in custom port or 1522
I want to install Oracle 10g Application Server in Port 1522 or some other port as in port 1521 Oracle 10g database server is already installed.
But every time I try to install Oracle 10g Application Server it give the warning about 1521 port and then start installing on same 1521 port automatically.
What should I do if I want to install in some other port ?
Please help
ThanxAs a method, to install an OAS on a custom port,
1) make a file called staticports.ini and define your components/ports there.
2) on the Specify Port Configuration Options screen, select Manual and specify this file.
Follow this link for details for 10g.
http://download.oracle.com/docs/cd/B14099_19/win.1012/install.1012/install/reqs.htm#CHDJACIG
However, there are ways to use the same port for OAS and DB depending upon the version of your listener. Check the version of your DB Listener, and if it is 10.1.0.2 or higher then you are just good to go with automatic port assignments.

Are "Back to my MAC" and "Port Forwarding" mutually exclusive?
I have been using APExtreme and Port Forwarding successfully for several weeks now. The PF is to allow access to game players on a PC which acts as a server on the web. All Good.
One more thing, I have a ISP provided wireless modem/router to talk to the cable and the world. It seems to work either bridged or un-bridged.
I have disabled the wireless on the ISP's modem/router. (Actually the ISP's device doesn't hold a candle to the APE.)
Still all good.
So the firewall is on in the APExtreme and none on the modem router, and I have a port defined for my gamers to get access to my server in the APExtreme.
I now want to implement Back to my MAC on my MBP and my other Apple devices. I believe these use iCloud for which I have an account and it seems to be working well with my iPhone.
In Properties, when I select BtmM, iCloud says communications will be slow if I have port forwarding on. Also I will not be able to use the router function in my Modem/router.
I'd really like to have the modem/router firewall up, and do the port forwarding there, but the BtmM will likely not get through.
So what does anyone suggest?
Can I use BtmM and port forwarding without too much degradation?
Please advise.
Thanks
BarryTo best answer your question on whether the two are "mutually exclusive," let take a look at how Back to My Mac (BTMM) basically works.
BTMM - General Requirements
OS X Leopard 10.7.3+
Active iCloud account. Each Mac & the AirPort router, that will be relying on BTMM, needs to be configured with the same account.
A publicly reachable IP address for your router.
A router that supports either NAT-PMP or UPnP. For AirPorts, be sure it is running 7.6.1+ firmware.
BTMM uses TCP port 5354 and UDP ports 4500 & 5353 for communications.
BTMM - Basic Communication Flow
For a computer connected to the Internet via a router, BTMM "asks" the router for its configuration information. For a router, like your AirPort, that uses NAT-PMP, BTMM will ask the router to assign arbitrary public ports. In turn, the router will provide these port assignments (& the router's Public IP address) back to BTMM.
BTMM then sends this information to the iCloud account. In background iCloud updates a special set of DNS entries to be used by BTMM. These entries are then made available to all BTMM clients using your iCloud account. When a computer, with BTMM enabled, uses your iCloud credentials, it automatically retrieves a list of all other computers/routers that are registered with the same account. All these devices should then appear under the SHARED section of the Finder.
When attempting to connect to a remote computer (or router), BTMM creates a secure connection to that remote device using the information from the iCloud account.
Once the connection is established, the devices can then communicate with each other.
So potentially, unless you are using Port Mapping for any of the ports BTMM uses, they should not conflict. -
How do I pragmmatically determine what comm ports my serial instruments are on?
I am building a test stand that incorporates 5 serial instruments; 2 digital loads and 3 power supplies. I can use my PC's device manager to figure out which comm port each device is on and set the VISA Resource Name so everything runs as expected. All is well at this point. The problem comes in when an instrument's USB connection is unplugged and replugged, at which point the system may renumber the port assignments; the result is that my program errors out, I have to figure out what port everything is on all over again, and change the VISA Resource Name for all of my instruments. While this is a minor annoyance for me as the developer, this would make the program unusable by the user.
While "don't ever unplug an instrument" is a sensible answer, the fact is that these things happen from time to time - like for calibration - so I want the program to work regardless of instruments being unplugged.
Is there a way to have the vi automatically identify what port each instrument is on?I've used a USB connected barcode scanner that appears as a COM port. If it is left connected to the same USB port the COM port remains constant but if it is disconnected and then put back into a different port the COM port changes. This sounds similar to your problem so I'll share how I solved things for my application.
The scanner I use accepts commands and will respond with a known string when I send a character 'I' via the serial connection. Using this I can see if the scanner is connected to the expected COM port (default port is stored in an ini file).
If this fails I create an array of possible serial ports by trying to open COM1 and checking for an error. If this does not generate an error I add it to an array. Next I try the same with COM2, COM3 up to COM16 (for example). This gives me a list of COM ports I can open.
I then iterate through the array trying for a response and stopping either when I get the expected response and continuing with the application or if the device is not found by the time I get to the end of the array I show the appropriate error condition to the operator.
If your instruments can return some kind of ID that will allow you to identify them as mentioned in another reply then this method could be used. Your 3 power supplies and 2 digital loads would need to be able to return a unique identifier otherwise you wouldn't be able to tell them apart and I think you'd possibly run in to problems. -
Problem: Socket
connection is not creating in machine, through utility program (MFC Dll), on ListDisplay service port - 3334 (on separate machine), while we are able to telnet on same ListDisplay service port - 3334 from same issue machine on same time
Environment: -
OS:
Windows XP SP2/7
Code:
VC 6.0
Dll: MFC
Problem Description: -
We have written a utility program which create socket (Using windows standard method [MFC]), and then make connection with another service (List Display) running
on port 3334 in different machine and retrieve the required list data. This program was working fine in almost all the machines.
But, we have received a severe intermittent issue on two machines. Client is facing issue in displaying the list data from port 3334.
Attempt: -
First we tried to debug code, and we come to know that socket is not creating in utility program. So we tried to telnet on ListDisplay service port 3334 and we were surprised that we were able to telnet, then we opened some more
telnet window on same port 3334 around (6 to 8) window, and each cmd connected properly. But we were not able to create socket from utility program.
Problem is severe because issue is intermittent.
We have tried all the way, but we are not able to figure it out, that what can be the exact problem and what are the conditions, when utility program will not
connect with ListDisplay service on port 3334.
Kindly assist to resolve this issue. For any help, we would be really thankful.Hi,
According to your description, it seems that you have created an utility program which is making connection with another service port 3334, however, two clients are facing issue in display the data list from port 3334.
Port: 3334/TCP
3334/TCP - Known port assignments (1 record found)
Service
Details
Source
directv-web
Direct TV Webcasting
IANA
Since the port 3334 is used by directv-web service, I'd like to suggest check this service it is working well on the problematic clients.
1. The client can be resolved in DNS well? Please run "nslookup" in the prompt command.
2. Is there any 3rd party application interrupting? Do test in clean boot.
2. Strongly suggest you run process monitor tool to analysis it.
I am looking forward to your reply if you have any updated on your side.

Hp officejet j6450 port assignment changes each time i start up.
When I startup, the printer always comes up in "offline status", and I cannot figure out how to reset to online. The problem seems to be that each time the printer syncs up with the wireless router, the port assignments change, so I have to "discover" the correct port and reset that via the Windows control panel properties for the printer. How can I set this such that the port assignment remains constant? or is there some simpler solution? Thanks.
Let's set a static IP address for the printer:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). You can find the DHCP range of the router using its internal settings page or in its manual. Use the CD that came with your router or type the router's IP address (ends in .1) into a browser.
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Enter your router's IP (on the Network Config Page) for the gateway and first DNS. Leave the second one blank.
- Click 'Apply'.
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you may need to redo 'Add a Printer' using the new IP address.

Two FTP ports on a single solaris server
can i have two FTP ports on single Solaris server ? If yes, HOW ??
Hi adiyakiran,
This is possible in third party ftp server wu-ftpd. you can download it from http://www.sunfreeware.com.
read wu-ftpd faq URL: http://www.wu-ftpd.org/wu-ftpd-faq.html
Testing on a different port number then ftp:21
This can be done from the command line or with a special definition in /etc/services ,/etc/inetd.conf. For command-line, look up -P and -p in the ftpaccess(5) manpage.
To set up with special definitions, add 2 ports with consecutive numbers in /etc/services, and then start wu-ftpd on these ports. Add to /etc/services something like :
ftptest 4021/tcp #command port
ftptest-data 4020/tcp #data port
Then start wu-ftpd from /etc/inetd.conf like :
ftptest stream tcp nowait root /usr/etc/in.ftpd in.ftpd
The key is the name 'ftptest' which associates the port assignment in the /etc/services file to that in the inetd.conf file. Make certain the choice of ports in /etc/services (4021 and 4020 above) are from the local use list and don't conflict with other port assignments (see RFC1700, ASSIGNED NUMBERS). One important subtlety. The data
port is not really derived from the data port declaration in the /etc/services file. The FTP specification (RFC765) states the data port is defined as one less than the command port. However, including the data port declaration in the /etc/services file prevents it from being accidentally assigned to something else.
Thanks.

senthilkumar.
