i'm not sure if i'm experiencing the same problem as the OP, but recently (don't know since when, exactly) i also can't get get my network up on eth0 once it's gone, like after suspending to RAM.
System: Host: laptop Kernel: 3.6.6-1-ARCH x86_64 (64 bit) Desktop: KDE 4.9.2 Distro: Arch Linux
Network: Card-1: Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller driver: r8169
IF: eth0 state: up speed: 100 Mbps duplex: full mac: c8:60:00:02:f1:09
restarting NetworkManager.service doesn't help. /etc/resolv.conf is correct, 'ip route' shows the proper routes, and ifconfig says that eth0 is up & running.
i can ping my own IP, but nothing else, neither internet nor LAN. the only thing that brings the network up again is a reboot (warm is fine). couldn't find anything in journalctl or everything.log (i'm keeping syslog-ng running for now). oh: i'm running systemd, since a couple months, and w/o problems until now.

Attansic L1 eth0 keeps constantly going down then up

As per title, eth0 keeps disconnecting and reconnecting especially during high load but not when idle, most likely because, well, it's idle. I have no idea if it's a driver problem or just a hardware defect, though I hope it's not the latter.
I'm using the vanilla Arch 64 bit kernel. The problem presents itself even on a 32 bit kernel and even with the ufw firewall disabled. However, I haven't flushed the rules after disabling the firewall which I will try later. Here are more details about my ethernet controller and sysctl.conf:

Temperatures look fine. Environment: around 28 C, CPU cores: 45-48 C, Nvidia graphics card: 62-68 C (8600M GT has always been that hot for me even older generations, again no idea why).
If it's hardware-related, I could save up for an ethernet to usb card or an ethernet express card. I'm more inclined towards an express card because of USB's CPU utilization and shared bus between all USB ports and I'd rather use it for external devices like HDDs. However, ethernet express cards are rather expensive, between 25 and 60 euros here, and I don't know if I should opt for a cheaper alternative which could lack shielding or be a clone.
Any help is appreciated greatly. Thank you in advance.
Edit:
Forgot to add dmesg's output.

Another thing. Disabling wake-on-lan on eth0 has no effect, even when done manually with ethtool, the output shows that wol is disabled but on poweroff the ethernet port's led on the router to which the laptop is connected is still on. I guess this could point to a defective ethernet controller, sigh.

You know, it sometimes helps to be specific.
Drive make, model, even firmware.
Seagate had a bunch of drives last year that would take 90 minutes to wake from sleep that drove people crazy (but seemed to be mostly or more common with iMac).
Hardware Monitor has a warning and probably something in the readme (those things you are suppose to read before installing?).
Stripped down system and minimal extras really does prove to to work better, fewer "side effects" and less trouble.
And when you do have your system installed, backup. Don't use it for anything else. I have had to resort to one of those backups more than I like now with Mac Pro. Put it on a FW400 drive and put it on a shelf.
Testing - make a list of what you add or change. Then let it run for a couple days that way before adding something else.
Zap the PRAM and reset the SMC. Run Apple Hardware Test. Maybe there is a problem - or you have a USB or FW device that interferes. Or driver.
In some ways, I think Vista and XP lets you see and control all the startupitems better.

Wireless Network Connection keeps going down

I have an Intel WiFi Link 5100 using the iwlwifi driver. The network comes up when I boot and works fine for a while, then suddenly stops. The card is still recognized, but I can't bring up a connection.

Power management is already disabled, you can see that from the output of "iwconfig wlp2s0". It was the first thing I tried. I also tried turning off wireless N which was suggested in the wiki and that did not help either, so I caved and posted to the forums.

RAC and instance goes down, transaction state?

I was talking to our physical DBAs, and they told me that when the RAC node you're connected to goes down:
1) if you're mid-query, your process gets transferred to another node
2) if you're not currently running a query, but you are in the middle of a transaction (ie no rollback or commit), that you lose the state of your transaction
I've seen 1) in action, but I haven't heard anything like 2). Is it true? They couldn't remember if they'd read it in the manuals, but they had heard it mentioned on more than 1 occasion during demonstrations.
-Chuck

What version of Oracle?
What kind of Application?
For most of the history of OPS/RAC if you are connected to an instance in the middle of a transaction or not when the instance you are connected to dies you must reconnect. Only if an Oranet fail-over connection was configured could you successfully reconnet asking for the same instance, though you would actually be connected to one of the available instances.
Any work in process was rolled back by another node.
Only with the advent of automatic transaction failover, ATF, would work on the dieing instance transfer to another instance. This works only if the application is coded to perform this task and when it first came out only for Select statements.

If Oracle DB Connection goes down,it should reconnect the DB again

Hi All,
I have a serious problem while running java process all the day. Sometimes I get following errors:
1. (***ERROR) java.sql.SQLException: OALL8 is in an inconsistent state.
2. (***ERROR) java.sql.SQLException: Io exception: Broken pipe
(***ERROR) java.sql.SQLException: Io exception: Broken pipe
(***ERROR) java.sql.SQLException: Closed Connection
3. (***ERROR) java.sql.SQLException: No more data to read from socket.
The above exceptions are not coming everyday.But sometimes it gives exceptions and because of that my java process will not run until it restarts the program.
I do know, because of oracle server down some of exceptions are coming. But what I wanted to do is if once the oracle server is up , my java application has to reconnect to the DB.
My idea is when java throws SQLException because of oracle server down, in the exception block it has to reconnect to the DB again by checking for right SQLERROR.
I am using JRE 1.4.2_10, JDBC Thin driver and Oracle 10g.
About Oracle DataSource am using JDBC 3.0 concepts which includes
OracleConnectionCacheManager and
Oracle DataSource
Can anybody help me on this to resolve the above exceptions.
Thanks in advance.

Actually, we are implementing Fast Connection Failover in our
application. Wwhenever one server instance goes down, java has to
map to another instance by taking all the required connections and
when server backs up then oracle has to do load balancing with all
the server instances.So you do already solve connection problem, right?
In the Java application, it sends array of hundred records to oracle all
the time. Is it because of sending huge arrays it is giving exception
java.sql.SQLException: OALL8 is in an inconsistent state.
Please help me out in solving the exceptions am getting.i think the exception raise not because you sending a huge arrays,
but because the connection broken in the middle of sending array.
you can get another connection when that exception occurs.
i'm not sure... i hope this can help you about handling that exception :
boolean success = false;
// will repeatly get available any connection until your transfer successfull
// or datasource does not has connection available anymore.
while (!success && isConnectionAvailable()) {
   Connection c = null;
   // Statement s = null;
   // ResultSet r = null;
   try {
      c = ds.getConnection();
      c.setAutoCommit(false);
      // send your array here
      // only commit when all data sent
      c.commit();
      c.setAutoCommit(true);
      success = true;
   } catch (SQLException sqlEx) {
      if (sqlEx.getErrorCode() == SERVER_DOWN) {
         // not sure this is needed...
         // when connection broken your partial sent data will not saved in db
         // because we set off auto-commit.
         // & actually calling rollback when connection is broken only raise
         // another sql exception ;P
         if (c.isValid(0)) c.rollback();
         // log exception information
   } finally {
      // close result set
      // close statement
      DbUtils.closeQuietly(c);
}

We have been experiencing issues with SSRS over the past 5 weeks, the service goes down frequently. And it comes up only on reboot of the server.

Hi SThiyag,
Based on your error message, it may be related to the “SecureConnectionLevel” in the RSReportServer.config file. Please go to C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\ReportServer, use Notepad to open the RSReportServer.config,
modify <Add Key="SecureConnectionLevel" Value="0"/>, change the value into "1" or "2".
(Note: Please backup the file before modify it.)
Acceptable values are:
3 Most secure—Use SSL for absolutely everything.
2 Secure—Use SSL for rendering and methods that pass credentials but don't insist on it for all SOAP calls.
1 Basic Security—Accepts http but rejects any calls that might be involved in the passing of credentials.
0 Least Secure—Don't use SSL at all
Here is a blog for error message "The underlying connection was closed...", please refer to the link below:

I am having a macbook pro 13" whenever I connect my reliance net connect to it the volume goes down by 50% automatically can anybody help me out?.

I am having a macbook pro 13" whenever I connect my reliance netconnect to it its volume goes down by 50%...

The problem is the Reliance software. You can verify this in the crash report. Try bypassing the Reliance software and just use the Network System Preference pane. Enter the same infromation there as you would in the Reliance software. Then hit "connect." It's worked pretty well for me.

Router goes down after Wi-Fi connecting my iPhone 5s

Hello,
Yes, simple as that, every time I connect my iPhone 5s to the home broadband, the router goes down for a few minutes and then it comes back, then goes down again and on ... (Never ending loop).
I made sure that it's related to my iPhone when the browser gone offline on my Macbook, when I turned the Wi-Fi off in my iPhone the router was on again.
Could it be a conflict or something?
Any suggestion will be good!
Many thanks and much appreciated.

Resetting Network Settings means that the saved password that enabled your iPhone to connect to your WiFi router was erased. You are now reentering that password. Most likely you are entering the password incorrectly or are entering an old password or the wrong password.
Check that the password that you are using is absolutely, positively, the correct and current password for your router. Make sure that you are not confused l with 1, O with 0, etc.

Hard Drive connected - Space Available never goes down when deleting files?

I have tried 2 different USB drives connected to the new airport N router.
Both drives work fine, an 80 GB maxtor, then replaced it with a 500GB usb seagate drive. Both drives have the same problem.
I only hook one drive up and copy over files to the drive. The space available shows up fine, but when I delete any files, the space available never goes down.
Any ideas how to fix this or is this just a nice big glitch?

Anyone with a hard drive connected to the N router.
Just copy some files the drive, then delete them while watching space available. The space available never goes down. What gives? Anyone else seeing this problem?

HT4060 Bought a new ipad and now its down to 28% so I am trying to charge it by the plug in but instead of going up its going down in %

Trying to figure out how to charge my new ipad wi-fi cellar. I plugged it in but instead of going up in % is still going down and its now showing me that its charging like a cell phone does. When I started to charge it, it was 28% now its 27%. Its plugged into a wall.

The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html

Secondary DNS failing to redirect clients when Primary DNS goes down

I have a single domain with two Windows 2008 servers, DC1 (physical) and DC2 (virtual). Both servers run DNS and are GC servers, and the entire domain is on the same subnet (192.168.0.x).
All clients on the network are configured to use DC1 as primary DNS, DC2 as secondary DNS.
DHCP is enabled only on DC1. (This might be part of the issue, not sure).
The problem is that when DC1 goes down for a reboot or repair, we lose access to the internet from our clients. Trying to pull up any website results in a "Page cannot be displayed" error. DC2 is available during this time and can be
pinged from any client but does not resolve DNS requests, even if I specify it as the primary DNS server on one of my workstations. However I can log on to DC2 locally and browse the web.
Here are the results of a DCdiag /dnsall from DC2 (I bolded areas of concern):

Looks like it may be trying to forward to a machine that's down (DC1 and another 192.168.0.7) and root hints aren't available.
Check out this article:
http://technet.microsoft.com/en-us/library/ff807391(v=ws.10).aspx
See if you can enable DNS access through the firewall to the Internet if it's not already available. Try to match whatever forwarder settings are on DC1, or remove them entirely and let the server resolve DNS from Internet root servers. Alternativly,
you could change your forwarder to a public DNS server you have access to, your ISP should supply this or you could test with something common like 4.2.2.2.

when i try to install oracle 10g i find this problem i wish you help meIn the future please work from a command line and use copy and paste to put commands and results in your posts. Many people's corporate nets block access to blog sites.
I have recently blogged extensively on this very subject. See edstevensdba.wordpress.com. I can't post a link to the exact article, because my corporate website blocks access to blog sites. I have also, many many times posted on this error in this forum, which a cursory search would have turned up. But once again, back by popular request:
=================================
ORA-12154: TNS:could not resolve the connect identifier specified
This error means one thing, and one thing only. The client could not find the specified entry in the tnsnames.ora file being used.
As a follow-on to that statement, remember that when you use a dblink, the database in which the link is defined is acting as a client to the database that is the target of the link. So in this case, the tnsnames.ora file on the host of your source should have an entry for your target db, as defined in the db_link.
And for the umpteenth time ... this error has NOTHING to do with the status of a listener. The connection request never got far enough to reach a listener. If anyone tells you to check a listener in response to ora-12154, they are not paying attention, or do not understand how TNS works. This error is the equivalent of not being able to place a telephone call because you don't know the number of the party you want to reach. You wouldn't debug that situation by going to the other guy's house and testing his telephone, or by going to the phone company and testing the switchboard. And you don't debug a ORA-12154 by checking the listener. If I had a top ten list of "Incredibly Simple Concepts (tm)" that should be burned into the brain of everyone who claims to be an Oracle DBA, it would include "ORA-12154 Has Nothing To Do With The Listener".
=================================
A couple of important points.
First, the listener is a server side only process. It's entire purpose in life is to receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It creates the connection. It doesn't sustain the connection. One listener, with the default name of LISTENER, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners or to name the listener as if it belongs to a particular database. That would be like the telephone company building a separate switchboard for each customer.
Additional notes on the listener: One listener is capable of listening on multiple ports. But please notice that it is the listener using these ports, not the database instance. You can't bind a specific listener port to a specific db instance. Similarly, one listener is capable of listnening on multiple IP addresses (in the case of a server with multiple NICs) But just like the port, you can't bind a specific ip address to a specific db instance.
Second, the tnsnames.ora file is a client side issue. It's purpose is for address resolution - the tns equivalent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
Assume you have the following in your tnsnames.ora:
larry =
(DESCRIPTION =
 (ADDRESS_LIST =
 (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
 (CONNECT_DATA =
 (SERVICE_NAME = curley)
)Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larrytns will look in your tnsnames.ora for an entry called 'larry'. Finding it, tns sends a request through the normal network stack to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the standard networking process delivers the message to port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, the listener will spawn a server process to act as the intermediary between your client and the database instance. Communication to the server process will be on a randomly selected available port. At that point the listener is out of the process and continues to user port 1521 to await other connection requests.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"
Third: If the client is on the same machine as the db instance, it is possible to connect without referencing tnsnames and without going through the listener.
Now, when you issue a connect, say like this:
$> sqlplus scott/tigertns will attempt to establish an IPC connection to the db instance. How does it know the name of the instance? It uses the current value of the enviornment variable ORACLE_SID. So...
$> export ORACLE_SID=fred
$> sqlplus scott/tigerIt will attempt to connect to the instance known as "fred". If there is no such instance, it will, of course, fail. Also, if there is no value set for ORACLE_SID, the connect will fail.
check executing instances to get the SID

ERROR:
ORA-12162: TNS:net service name is incorrectly specifiedOk, that is how we get from the client connection request to the listener. What about the listener's part of all this?
The listener is very simple. It's job is to listen for connection requests and make the connection (server process) between the client and the database instance. Once that connection is made, the listener is out of the picture. If you were to kill the listener, all existing connections would continue. The listener is configured with the listener.ora file, but if that file doesn't exist, the listener is quite capable of starting up with all default values. One common mistake with the listner configuration is to specify "HOST=localhost" or "HOST=127.0.01". This is a NONROUTABLE ip address. LOCALHOST and ip address 127.0.0.1 always mean "this machine on which I am sitting". So, all computers are known as "localhost" or "127.0.0.1". If you specify this address, the listener will only be capable of receiving requests from the machine on which it is running. If you specified that address in your tnsnames file - on a remote client machine - the request would be routed to the machine on which the requesting client resides. Probably not what you want.
=====================================

Wireless APs going down randomly

Hi All
We have a situation where wireless access points are just going down randomly on our network. The situation is as follows:
We have 2 Cisco 5508 WLCs (licensed for 250 APs each, with more licenses en-route), both running software version 7.2.103.0. Then we have a large-ish number (±300) of Cisco AIR-CAP3502I-E-K9 APs connecting to these two controllers. The APs are either connected to Cisco WS-C2960S switches, or in "older" areas of the network they are connected to WS-C2950 switches. We do not have PoE switches installed yet, so all APs are powered by power injectors (AIR-PWRINJ4=).
Anyhat, all the access points are in FlexConnect (previously HREAP) mode, and they all connect via trunk ports to the switches in order to get the VLAN per SSID working. Both controllers are in the same mobility group, and both are in the DNS as "cisco-capwap-controller" as they are load balancing. The APs are installed about 25m apart in most areas. There is one installation where two APs are about 10m apart, but this is due to the shape of the building in which they are installed. We have no autonomous APs deployed at all...
The problem is that some access points work for about a day, and then they just disassociate with whichever controller they were associated to, and then they just fall off the network completely. Both WLCs, the NCS, and the network monitoring system (WhatsUp Gold) show the affected APs as physically unreachable. Looking at the trunk port on the switch, it shows that the port is up and the line protocol is up, input rate is 0 bits/sec, and output rate is up to 70,000bits/sec. There are no input or output errors on the switch port. Here is the output from one such switch port:

Connecting a console cable to an affected AP is fruitless, as the AP appears to be unresponsive while it is "down". Rebooting the AP, then connecting a console cable works, but then you've lost your syslogs. Looking at the Ethernet interface on the AP, it appears as if the interface is picking up a lot of errors, especially CRC errors, which would indicate a physical cable problem.
I got our cabling contractor out to do a cable test again, and it passes every time. We have them test both the Systimax and the Molex cable installations of affected APs, and all is OK. They use a Fluke MicroScanner² cable tester which certifies the Cat 6 cable from patch lead to flylead. No problems there, and I trust that the cable is 100% as tested.
So I swap the power injector of an affected AP (let's call it AP A) with an AP that is not affected by this (let's call this one AP B), and AP A goes down again after a day, or sometimes only a couple of hours. AP B remains operational as usual. If I swap AP A out with a new AP (AP C), then AP C starts showing the same symptoms after about a day, and then it also just goes down. When "suspect" AP A is installed somewhere else, then it works and stays operational for, well, 58 days now. Changing the switch/switch port also makes no difference.
This happens to one of the APs that are part of the "10m apart deployment", but it also happens to another AP that is completely on its own in a building far away from any other wireless source, so I cannot think that this could be the problem. I happens to an AP that is less than 100m away from its closest WLC, and it happens to an AP that is more than 350km away from its closest controller. All the other APs deployed in our remote campus (350km fibre link) are 100% OK. It happens to APs connected to the older WS-C2950 switches as well as the brand new WS-C2960S switches.
I am at wits end with this one. Where could the problem be? I trust the "Big Green" company that does our cable installations, and I trust the equipment they use. I also trust both Systimax and Molex to be very good products. And I do trust Cisco, as this is the only network equipment we deploy.
Where to from here?

Connie

This issue has now been resolved. Details can be found here: http://www.cisco.com/en/US/partner/ts/fn/635/fn63537.html.
Here is the short version:
Problem Description:
Calibration between DRAM and processor on AIR-CAP350x and AIR-LAP126x results in Access Points (APs) failing to boot properly. One symptom includes a white LED and no console output.
Background:
The root cause is the DDR memory calibration process that was performed on the Access Points (APs) at the time of manufacture. The fix recalibrates the existing memory hardware, so it will operate more reliably.
Workaround/Solution:
The fix for this issue is now publicly available. Go to www.cisco.com to obtain Access Point (AP) IOS code version: 15.2(2)JA or later and/or WLC software version: 7.0.235.3 (or later 7.0 release), 7.2.111.3 (or later 7.2 release) or 7.3.101.0 (or later 7.3 release).
As of June 2012, new AP3500 and AP1260 products with version ID (VID) V02 are free of this issue.

Interface goes down with mds9140

Hi
I've a problem with both MDS 9140. The fc interface goes down and don't go up when I reboot a device connected to them with a fiber. To solved the problem I need to remove the gbic and plug it back again. I use the following version of software
Software
BIOS: version 1.0.8
loader: version 1.1(2)
kickstart: version 1.2(1a)
system: version 1.2(1a)

It is probably a software defect where if a port is up for over 248 days, Once link is lost, it will not come back w/o a shut/no shut or manual intervention as you describe. This issue is resolved in the 1.3.4b and above code. For a 91xx, this would be a disruptive upgrade. Or, simply issue a shut/no shut on an affected port and you'll be good for another 248 days.

Please do help me........ how to resolve this.
Thanks.

Hi,
You could try increasing the java heap size, though sometimes an issue can occur if you are trying to delete a member when a workflow process has started, do you have one running?
Cheers
