Oracle restart: change network interface name

Hi all,
Env: Oracle Restart 11.2.0.3 w/ASM.
I've been trying to look up info about this without any luck so I hope some experts here can shed some light..
To improve redundancy we're planning to change the network configuration in our Oracle Restart environment from using 1 LAN interface to a bonded interface consisting of 2 interfaces.
So the change will be from using "eth0" to using "bond0" consisting of "eth0" and "eth1". Are there any changes that must be done in the Oracle Restart configuration to reflect these changes?
Thank you for your time.

[SOLVED] Network interface name keeps changing

My network interface name keeps changing between wlp2s0 and wlan0. This is a real pain, since I never know what name will be generated at boot. Most of the time it's called wlp2s0, so this is what netctl is set up to handle by itself. At boots were wlan0 is generated I have to connect manually.
I've tried making the name static by adding a rule to the /etc/udev/rules.d/10-network.rules. The rule i added was:
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="48:5d:60:7e:64:e9", NAME="wlp2s0"
Wlp2s0 is generated at boot alright, but I still have to connect manually with this solution. As if the "new" wlp2s0 is not recognized as the old one (same MAC). What gives?
This is on an Asus Eee 1001PXD, with the Qualcomm Atheros AR9285.

I've now been able to replicate the issue, and run the command:
journalctl -b
I did find the output:
mai 18 02:30:02 <hostname> systemd-udevd[126]: error changing net interface name wlan0 to wlp2s0: Device or resource busy
I haven't been able to process the whole output yet (I'll continue tomorrow if necessary), but I've found some things that I hope will clearify things. I get similar outputs to the following a lot throughout:
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: carrier lost
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: waiting for carrier

mai 18 02:30:04 <hostname> systemd[1]: Starting Network.
mai 18 02:30:04 <hostname> systemd[1]: Reached target Network.
EDIT:
I see now that this is later in time, so that's not so strange after all. I'll look some more.
EDIT2:
The error code that a name change i impossible is the first time the term 'wlan0' occurs in the log. However there's a line much earlier that talks about wlp2s0:
mai 18 02:29:59 <hostname> systemd[1]: Expecting device sys-subsystem-net-devices-wlp2s0.device...
But as I said, if this information doesn't help, I'll have a closer look at the output tomorrow. Getting late here in Norway now.

How to get active network interface name?

Hi All,
Can any one tell me how to get the currently active network interface name (Local Area Connection/ Wireless Network Connection/ other) either by using java SDK or win32 API.
Is there any function to get the active network interface name in java/win32?
Is there any procedure for it to get from observing registry keys.
I found NetworkInterface class in java but not yet succesful in getting the display name of active network interface.
Can anyone help me with partial code?
Please help me.

Use getLocalHost() then retreive the list of NetworkInterfaces and cycle through them until you find the one that has that address.

[solved] network interface names changed?

Hi,
I reinstalled arch on my laptop yesterday (hard drive failure). Normally, not to big a deal. Took me four hours to get arch installed. Why? couldn't for the life of me figure out how to get the wireless connected (ethernet connection unavailable, port is physically damaged). In the end, my fault, I should have tried iwconfig earlier.
It seems that my network interfaces have all changed names since the last time i installed. The wireless interface has changed from the sensible 'wlan0' to the mystical 'wlp4s0'.
also, eth0 is now enp9s0.
This has messed up a number of my scripts and above all is more than a little confusing, wlan0 feels right, wlp4s0 feels wrong.
Now, I'm not opposed to change. I like change, even if it breaks a lot of my scripts, but I like to know why something has changed to something less intuitive.
Why was this change put in place? I can't find any real info on it after 30 mins googling.
Can it be changed back through some setting somewhere without upsetting whatever problem it's supposed to fix?

Oracle Reports - Change Email Attachment Name

Hello,
I'm sending salary receipts in PDF via email using Report Server 10g. It's working but i want to change the PDF name, in order to appear the number of employee in the name (something like Receipt_00001.PDF)
I used to accomplished that in other versions using the DESNAME parameter, but now since its Web and via Reports Server that doesnt work :(
PROCEDURE EXEC_REPORT_SRV_FILE (WK_REPORT VARCHAR2 /* report name */,
WK_PROC VARCHAR2 /* process name */,
wk_file VARCHAR2 /*a parameter value that i use in the command below*/)
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESNAME,wk_file);
Where i call the EXEC_REPORT_SRV_FILE i tested like this below but just for doing this, the emails are no longer sent and it gives me the error in (**)
I done this because i think it would be in the 3rd parameter, but i was in doubt it could be in the 2nd one but i dont think so..
exec_report_srv_file (name_in ('PARAMETER.PR_DRIVE_APLIC')
|| name_in ('PARAMETER.PR_DIRECT_APLIC')

Executed successfully but there were some errors when distribute the output REP-50159: Executed successfully but there were some errors when distribute the output
I'm using Oracle Reports 10g.
This is so urgent that i joined this forum just for this (For now.. :) )
Thank you so much in advance for your time.
Best regards,
Nuno Neves.

- What is the difference between the reports that work and the ones that do not work?
- I would suggest to apply latest patchset 10.1.2.3

[SOLVED] systemd-udevd renames network interfaces

During install I enabled dhcpcd service like this:
systemctl enable [email protected]
Seems perfectly valid, eh? But after reboot network I've got the following messages:
[ TIME ] Timed out waiting for device sys-subsystem-net-devices-eth0.device.
[DEPEND] Dependency failed for dhcpcd on eth0.
dmesg | less
systemd-udevd[111]: renamed network interface eth0 to enp0s3
It appears systemd changes network interface names. But then I suppose [email protected] is to be removed:

old to Linux new to archLinux
jasonwryan -thanks!
Your post helped me figure it out why my Ethernet interface name was changed to enp0s3 and why - I like the old naming convention ethx easier for me to remember. So went the route with custom rules in /etc/udev/rules.d
Here is what I used.
70-my-net-names.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="08:00:27:3b:f3:cd", NAME="eth0"

Error in udev change of net interface name wlan0 to wlp3s0

My quite fresh installation of Arch has started having the following problem:
the udev rename of my wireless interface from wlan0 to wlp3s0 suddenly stopped working!
In journalctl, I find the following error line:
Jan 09 16:23:43 mole systemd-udevd[180]: error changing net interface name wlan0 to wlp3s0: Device or resource busy
I am using netctl, netctl-auto and netctl-plugd with wpa-supplicant and dhcpd. The issue seems to be that netctl tries to do stuff with wlan0 before udev can rename it, as a non-predictable race condition. Further down in journal, I have this (non-error) line
Jan 09 16:23:43 mole systemd[1]: Started (Re)store the netctl profile state.
Searching Google yielded me a few places talking about this, but no solution as I could see, and they were also possibly quite outdated.
My ethernet interface is properly renamed and works without issues. I should perhaps also mention that my install is now about 3 weeks old, and I have rebooted the machin a number of times before this behaviour started. In this time I also switched from netctl to wicd back to netctl, and the last switch was only a few days ago.
I have brainlessly tried various stuff, such as disabling netctl-auto and netctl-plugd for all interfaces, as well as adding a custom renaming rule to
/etc/udev/rules.d/10-network.rules
. Needless to say, this didn't resolve my problem.
In case it is important, I have the following services pertaining to networking running:
UNIT LOAD ACTIVE SUB DESCRIPTION
dhcpcd.service loaded active running dhcpcd on all interfaces
[email protected] loaded failed failed Automatic wireless network connection using netctl profiles
[email protected] loaded active running Automatic wired network connection using netctl profiles
netctl.service loaded active exited (Re)store the netctl profile state
netctl@wlan0_eduroam.service loaded active exited Networking for netctl profile wlan0_eduroam
polkit.service loaded active running Authorization Manager

systemd-udevd.service loaded active running udev Kernel Device Manager
systemd-update-utmp.service loaded active exited Update UTMP about System Reboot/Shutdown
wpa_supplicant.service loaded active running WPA supplicant
Is it right to have netctl.service activated?
Any help is greatly appreciated.
Thanks,
jsrn

Thanks for the reply, lspci. With the same no. as your question:
1. Right now I have both wlp3s0_[some interfaces] and wlan0_[same interfaces] since I need both interfaces. All of the names are correct, and their configs are the same expect of course for the Interface-line. I also have an enp0s25_dhcp for my wired connection.
2. and 3. The custom udev rule that I made after the problem started occurring is in /etc/udev/rules.d/10-network.rules and contains
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="a4:4e:31:cd:5d:64", NAME="wlp3s0"
I can't seem to detect that it has any influence or is even run. But on the other hand, it is exactly this that udev was already trying to do but failing.
4. I could of course do this. But shouldn't it work without conflicting with the udev rename? The wiki currently recommends exactly these two services.
Right now my system works, albeit more manually than I would hope. I am on wireless right now, but if I lose connection (bad reception here), then I have to stop the netctl service on wlan0, down the wlan0 link and then restart netctl on wlan0. Also, whenever switching wireless network or to wired, I expect to have to do similar tedious stuff.

How to change the Ethernet Interface name in Solaris 10

I have to install Oracle 10G RAC on three nodes with different ethernet cards, but the ethernet interface name must be the same which is the precondition for Oracle RAC installation.
So I want to know how can I change the ethernet name in Solaris.
For example, the ethernet name in the OS is "ce0", how can i change the interface name "ce0" to "e1000g0".
bash-3.00# dladm show-dev
ce0 link: unknown speed: 1000 Mbps duplex: full
ce1 link: unknown speed: 100 Mbps duplex: half
ce2 link: unknown speed: 100 Mbps duplex: half
ce3 link: unknown speed: 100 Mbps duplex: half
ce4 link: unknown speed: 100 Mbps duplex: half
ce5 link: unknown speed: 0 Mbps duplex: unknown
Thanks in advance.

You can't. The ce or e1000g refers to the driver as well as the adapter itself. The only exception I am aware of is: the ipge and e1000g which both refer to the Intel Pro 1000.I'm pretty sure I've renamed a driver in the past (and all references to it in name_to_major, path_to_inst, driver_aliases, and minor_perm) and had it function just fine after 'plumb'ing it up. However I just tested this by trying to turn a 'pcn' driver into a 'foobar' driver on a vmware box. It looks like everything works except some internal bits of the driver continue to create one file with 'pcn' in the name instead of 'foobar'. And since this is Solaris 10, the /devices filesystem is dynamic and read-only. I can't seem to force the change.
So while this may be possible with some drivers (and maybe only on older versions of the OS), it doesn't seem to be generally possible for all drivers on Solaris 10.

Oracle 10g RAC - public network interface down

Hi all,
I have a question about Oracle RAC and network interface.
We're using Oracle 10gR2 RAC with two nodes on Linux Red Hat.
Let's assume that the public network interface goes down.
I would like to know what happens with existing connections
on node with network interface with problems.
Are connections frozen, actives?
Can the users continue to use theses existing connections using the another node of RAC?
I know that the listener goes down and any other connections is allowed.
Thank you very much!!!!

Can the users continue to use theses existing connections using the another node of RAC?If the interface is down? what do you think? All connections to this node will die. How does your application handle fail-over, does it attempt to reconnect or just have a complete application failure?
You should spend some time in a test lab where you can test this stuff for yourself. Read the documentation and there are tons of sites out there that purport to have all of your RAC/TAF/FAN/FAF questions. - I would read and trust the documentation first.

Public API/Interface name to import the payment information against invoice

Hi,
I want to get the Oracle supported Public API/Interface name to import the payment information against invoices(because there is a need to importing payment data against closed invoices from 11.5.5 to R12). Since I am not getting any standard oracle supported method, I am using the API AP_PAY_INVOICE_PKG.AP_PAY_INVOICE but while running it I am getting the following error:-
Payment API Error =ORA-20001: APP-SQLAP-10000: ORA-28115: policy with check option violation
occurred in
AP_AIP_TABLE_HANDLER_PKG.Insert_Row <-AP_PAY_INVOICE_PKG.ap_pay_insert_invoice_payments<-AP_PAY_INVOICE_PKG.ap_pay_invoice<-.
Regards,

The below query will meet your requirement, but payment amount won't matches with some cases see below .
1) Check Payment/EFT Payment for more than one invoice we will pay that time invoice amount is
not equal to payment amount, Payment amount is greater than Invoice Amount. This will be controlled in Report level.
if you develop report using this query, there you can control this issue.
SELECT aia.vendor_id, aps.vendor_name, aia.invoice_id, aia.invoice_num,
       aia.invoice_date, aia.invoice_currency_code, aia.payment_currency_code,

Get/set message interface name in adapter module

Hello,
From an adapter module, I'd like to get or even set the Message Interface name of the message that is handed over to the function "process" of the adapter module.
I've got two context's, sessioncontext and modulecontext. With both contexts, you can get values from that context. I'm not sure which context has the message interface name of the message currently being processed, and I'm also not sure what that value is called (moduleContext.getContextData("name");).
The reason for this is that sometimes you'd like to do something different depending on the type of message being processed.
If anyone knows how to do this, I'd be glad to hear.
Thanks in advance for any advice!
Greetings, Walter.

Hi Walter,
It is fairly easy to get the interface name. When you have extracted the XIMessage there is a parameter, which allows you get the Action, where you can get the interface name.
I have tried to change the interface name. You need to create a new message an copy the content from the old message over to this. This is a little tricky and I'm not able to get any code samples for you.

USB wireless adapter - interface name keeps changing

I have used different usb wireless (G) adapters with my 12" Powerbook G4.
Each was automatically assigned an interface name (BSD) such as en2, en4.
I recently updated to a Wireless N dongle (D-Link DWA140) which works great with my new Belkin Wireless N router.
I have had a few connection problems where the dongle was named as enNull.
After rebooting and re-entering the ip address via DHCP, I noticed that the same dongle has been renamed each time e.g First as en5 then en6, 7 and 8. It's now called en10
It works fine but is it possible to reset the name/number of this wireless adaptor using something like ifconfig in the shell Or some other way. I understand that en0 is built-in ethernet and en1 is Airport. I have 2 other dongles which are still identified as en 2 and en4. But my current dongle has an inflation problem and I would like to reset it if possible to a lower number.
Is this possible or am I mad to even consider it?
any help welcome.

That is very strange that PCI cards would keep changing names between reboots. Maybe you should investigate that to figure out what's going on. Check the dmesg and journalctl after each reboot and see what the interface is named as. Maybe that will give you some clues as to what "external" program is responsible in naming the interfaces.

Network share name keeps changing

I have setup my eMac to have the network share name eMac but it keeps changing into +eMac (2)+ does anyone know why?

well I do, but a short while later.
or some weeks or even month later, I can do it again.
this is a problem because I need to connect to it from my server.
the server is a Dell PowerEdge 1650 (I know, old, but it was cheap and it does the trick) which is running Linux Ubuntu Server 9.10 "Karmic Koala", since it's a server I did not install a DE(desktop environment) so I need to use the bash or shell (depending on what I do, since it has both)
how I connect it like this (on the sever):
+mount -t nfs "emac.local:/dev/macintosh HD" /storage/nfs/emac/+
the problem here: I use a DHCP, with DHCP reservation.
since I use DHCP reservation the IP should not change.
but the DHCP reservation doesn't really work correctly,
because of this, if my mac is offline (A.K.A off, I never disconnect it), the IP is in the pool, and thus can be assigned to a other computer.
since the IP may change depending on if it is on at a given time.
I need a way to always successfully identify my emac.
for this I use the network name.
and now it changes too!
which means that in order to find it I need to know if it still has the same network name, or what it's IP is.
I can find the IP from a web browser since it's my router who is my DHCP.
but the server doesn't have one.
so I'd have to use a other computer, since the router doesn't allow SSH/TELNET connections.

How to change network name on BT Hub 2.0?

Hi folks,
I've just set up my Broadband with BT here in the UK and all is well.
However, how do i change the network name from the default BThomehub?
I had a belkin router prior to this and i could change it easily by going into the routers home page but in the BT home page it shows the name of the hub/router but i can't change it?
Thanks.

You need to log into the home hub manager and select "settings"
Then select "advanced settings"
Then choose "Wireless" where you can change the Wireless name/SSID
Hope that helps.
