• Opening an oracle database crashes the service

  - by tundal45

  I am experiencing a weird issue with Oracle where the service started fine after a crash. The database mount went fine as well. However, when I issue alter database open; command, the database does not open, gives a generic cannot connect to the database error & crashes the service. Oracle support has not seen this issue before so it's pretty scary. The fact that there are no logs that give any leads as to what could be causing this is also scary. I was wondering if good folks over at Server Fault had seen something like this or have some insights on things that I could try. It's Oracle 10g running on Windows Server 2003. Thanks, Ashish

• Distributed file systems

  - by Neeraj

  I need to implement a distributed storage system for a set of nodes(devices) connected in a mesh network. So what basically my design goals are: The storage system should be capable of handling dynamic entry and exit of nodes. Replication (for fault tolerance). For this i am thinking of using a Distributed file system. Every node could access data in the other nodes in a transparent manner. Are there some simple, easily pluggable opensource implementations? Thanks for your thoughts!

• Does SpinRite do what it claims to do?

  - by romandas

  I don't have any real (i.e. professional) experience with Steve Gibson's SpinRite so I'd like to put this to the SF community. Does SpinRite actually do what it claims? Is it a good product to use? With a proper backup solution and RAID fault tolerance, I've never found need for it, but I'm curious. There seems to be some conflicting messages regarding it, and no hard data to be found either way. On one hand, I've heard many home users claim it helped them, but I've heard home users say a lot of things -- most of the time they don't have the knowledge or experience to accurately describe what really happened. On the other hand, Steve's own description and documentation don't give me a warm fuzzy about it either. So what is the truth of the matter? Would you use it?

• Both servers running keepalived become master

  - by pcent

  After a network failure,both servers running keepalived become master. When the network is reestablished, both keep the MASTER state. What could be causing it? Edited: Another information that might be relevant, each server has two NICs. Here is the virtual instance configuration: vrrp_instance VGAPP { interface eth0 virtual_router_id 61 state BACKUP nopreempt priority 50 advert_int 3 virtual_ipaddress { 10.26.57.61/24 } track_interface { eth0 } track_script { jboss_check #tomcat_check #interface_check #interface_check02 } notify_master "/opt/keepalived/scripts/set_state.sh MASTER" notify_backup "/opt/keepalived/scripts/set_state.sh BACKUP" notify_fault "/opt/keepalived/scripts/set_state.sh FAULT" notify_stop "/opt/keepalived/scripts/set_state.sh STOPPED"}

• Virtualised Sharepoint Backup Strategies

  - by dunxd

  I have a Sharepoint (OSS 2007) farm running on three virtual machines in VMWare ESX, plus a SQL Server backend on physical hardware. During a recent Business Continuity Planning event I tried restoring the sharepoint farm with only the config and content databases, and failed to get things working. My plan was to build a new sharepoint server, then attach this to a restoration config database and install the Central Management site on this server, then reattach the content databases. This failed at the Central Management part of the plan. So I am back to the drawing board on the best strategy for backup and recovery, with reducing the time and complexity of the restore job the main objective. I haven't been able to find much in the way of discussion of backup/restore strategies for Sharepoint in a VMWare environment, so I figured I'd see if anyone on server fault has any ideas or experience.

• Kerberos: connection from win app running from IIS to SQL failed

  - by Mikhail Kislitsyn

  I have an IIS web-application with Windows authentication and impersonation. This application connects to SQL server. In this case Kerberos works fine. But there is a problem. Web-application runs windows application (not .NET), which also connects to the SQL server. Windows application runs with IIS app user credentials and impersonates current site user to connect to SQL server. scheme: http://i.stack.imgur.com/2cgv7.png When delegation for IIS user is set to "Trust this computer for delegation to any service" everything works fine. But I can't use this type of delegation according to security requirements. When I set delegation to "Specific services" and choose MSSQLSvc SPN, connection from windows application fails with "ANONIMOUS" fault. WireShark shows "KRB5KDC_ERR_BADOPTION" packet. What I'm doing wrong?

• How do I connect to the serial console port os a Sunfire 280R?

  - by DrStalker

  We have a Sunfire 280R (old SPARC/Solaris server) that is refusing to come up after being relocated. We're trying to connect to the serial console port, but all we get is random gibberish on the screen. We've tried both connecting with a DB25DB9 adapter and using a DB-25-RJ45 adapter with a cisco RJ45-DB9 adapter to a windows laptop. We're configuring the laptop to 9600 baud, 8 bit, 1 stop bit, no parity. We've tried both no flow control and Xon/Xoff. We get the same results hooking up to the serial port on a working SPARC server, so it's probably something in our setup rather than a fault with the server. How do we get access to to serial console so we can work out what is stopping this box from getting to the network? Is there a special sun adapter we need to get/make to get the serial link working?

• RAID Read/Write Speed Gradually Slows

  - by Nalandial

  This is actually a server at home, but I felt it was sufficiently complicated as to not have it on SuperUser and could easily apply to a professional situation. I have a file server running Debian (Lenny 5.0.4), and it has an XFS LVM on top of a RAID 5 with the OS drive separate from the RAID. It's also running apache, samba, and postgresql. Side note: before anyone asks, I'm using RAID5 because I get more bang for the buck on raw drive space, and still have some fault tolerance. When the box is started (via shutdown or reboot) reading/writing to it's samba share maxes out the gigabit network connection. Over time, this slowly degrades eventually becoming < 10MB/s; however, when rebooted the speed returns to maxing out the connection. Why is this happening, and is there a way to 'clear' out whatever's causing it without taking the server down? Thanks in advance!

• Reconnoiter - Anyone using it?

  - by Marco Ramos

  Reconnoiter is a new tool in the world of monitoring. It is not only a trending tool but also alerting/fault detection one. In my particular case, I reckon that it's in the trending capacities that Reconnoiter has a very huge potential. One of the premises Recoinnoter is built upon is that RRDTool large installations are very inneficient regarding I/O and I think this is RRDTool major problem. One of the things that would make me change from Cacti is, obviously, the cost of change and the learning curve. So, any of you has experience with Reconnoiter? How's the learning curve? Was it difficult to move from RRDTool frontend applications (Cacti, Munin, Ganglia) to Reconnoiter? I'm looking forward to read your opinions.

In my site, I have this link: http://site/search/?v[1]=myid it work nice, I think index.php handle it.

• ApplicationPool in IIS 7.5 crashes with identifty set to NetworkService

  - by Ravi

  We have a web application running on IIS 7.5 with the identity of the Custom Application Pool set to NetworkService. This was working fine for some days and now the application pool has gone in to a stopped state. The following error message is displayed in the Event Viewer Faulting application name: w3wp.exe, version: 7.5.7600.16385, time stamp: 0x4a5bcd2b Faulting module name: ntdll.dll, version: 6.1.7600.16559, time stamp: 0x4ba9b29c Exception code: 0xc0000005 Fault offset: 0x00038c19 Faulting process id: 0xa28 Faulting application start time: 0x01cbb2e5707aa2b2 Faulting application path: C:\Windows\SysWOW64\inetsrv\w3wp.exe Faulting module path: C:\Windows\SysWOW64\ntdll.dll Report Id: ae3f0610-1ed8-11e0-abf8-000c297f918f We are able to start the application pool only after changing the identity to LocalSystem. Why does the application pool fails to run with identity set to NetworkService. Can any one help us resolving this issue?

• nagios wrongly reports packet loss

  - by Alien Life Form

  Lately, on my nagios 3.2.3 install (CentOS5, monitoring ~ 300 hosts, 1150 services) has sdtarted to occasionally report high packet loss on 50-60 hosts at a time. Problem is it's bogus. Manual runs of ping (or its own check_ping binary) finds no fault with any of the affected hosts. The only possible cures I found so far are: run all the checks manually (they will succeed but it may act up again on next check) acknowledge and wait for the problem to go away (may take several ours) I suspect (but have no particular reason other than single rescheduled checks succeeding) that the problem may lay with all the checks being mass scheduled together - in which case introducing some jitter in the scheduling (how?) might help. Or it may be something completely different. Ideas, anyone?

• Apache Serving 403 Forbidden after OS X Snow Leopard Upgrade to Version 10.6.6

  - by Ian Oxley

  I've just upgraded my MacBook Pro to OS X Snow Leopard version 10.6.6 and now Apache is misbehaving: requests to http://localhost/ generate a 403 Forbidden response -- FIXED requests to any of my virtual hosts seem to generate a 200 Ok response, but contain zero bytes Some further info that might be useful: I'm using the Apache that comes bundled with OS X. I'm using PHP from http://www.entropy.ch/software/macosx/php/ (which is in /usr/local/bin) I've had look at the Apache error log and the only error seems to be the following: [notice] child pid 744 exit signal Segmentation fault (11) I'm completely stumped by this. Any help would be much appreciated. UPDATE Ok, I've managed to resolve the 403 Forbidden error thanks to http://techtrouts.com/mac-os-x-105-web-sharing-forbidden-403-on-httplocalhostusername/ I'm still having the second problem though for any request e.g. this now happens when I request http://localhost

• What is a fairly accepted endpoints to concurrent calls ratio for a PBX?

  - by Logan Bibby

  Hey guys! Not too positive about the relevance of this question to Server Fault, but I'll let you guys poke around at it anyway. :) I'm trying to figure out what an accepted ratio of endpoints to concurrent calls on the "average" office PBX. I'm defining concurrent calls as any call being placed, including internal calls. I'm not going to be considering call centers into this ratio, I'll be looking at those differently, anyway. To give you guys a little history behind the question: I need this ratio to be able to figure out decent specs for a virtual PBX service I'm going to be rolling out within the upcoming months. The ratio will determine the number of trunks needed per PBX system. -- Logan

• Internet Dropping?!

  - by stead1984

  I have a virtual DC running DNS and Routing and Remote Access, that routes ALL workstations Internet traffic out to the Internet, this works fine but noticed that the Internet drops occasionally. I've checked with our service provider (Managed Communications) and they are adamant that it's not their fault. The Internet drops seem to affect everyone. We also have a server configured to use the same Internet service on a different network over a site-to-site VPN connection which also suffers from packet drops. I've spoken to Cisco and have done many tests with Cisco and they believe the problem is down to the ISP. I'm wondering if it's a DNS issue, as the Internet service uses OpenDNS. Any ideas?

• Creating a vm using Hyper-V causes the host of BSOD

  - by Arcass

  Hi, Problem description: When I try to create a virtual machine, the host bsod part way through the process. From the logs in lookes to fail/hang on the "Creating new VirtualDisckDriver with new VHD" step. The BSOD error code is SYSTEM_SERVICE_EXCEPTION : STOP:0x0000003B When the machine has finished restarting, it looks to have created the vhd and XML files for the vm but it isn't accessable. I have two server bothing behaving in exactly the same way, so I don't believe it's a hardware fault. Has anyone had a similar experince? How did you resolve the problem?

• Initiate a PHP class where class name is a variable

  - by ed209

  I need some help with an error I have not encountered before and can't seem to find anywhere. In a PHP mvc framework (just from a tutorial) I have the following: // Initiate the class $className = 'Controller_' . ucfirst($controller); if (class_exists($className)) { $controller = new $className($this->registry); } $className is showing the correct class name (case is also correct). But when I run it I get this in the apache error log (no php error) [Wed Mar 31 10:34:12 2010] [notice] child pid 987 exit signal Segmentation fault (11) Process id is different on every call. I am running PHP 5.3.0 on os x 10.6. This site seems to work on 5.2.11 on another Mac. Not really sure where to go next to debug it. I guess it could be an apache setting as much as a php bug or a problem with the code... any suggestions on where to look next?

• Exchange 2007 backup / restore

  - by Matt

  To explain my situation I have a exchange 2007 server and I have recently upgraded to SP2 so that I can use windows server backup to take an "exchange aware" backup of the server. Is there an easy way of restoring this data onto a second server to which I have pre-installed server 2008 / exchange 2007 without upsetting my current exchange server set-up. Also is there a better way to do this, such as running one as a fall over should the primary exchange server develop a fault. I am still new to all this so please excuse any stupidity in my questions. Thanks in advance for any help and assistance

• The canonical "blocking BitTorrent" question

  - by Aphex5

  How can one block, or severely slow down, BitTorrent and similar peer-to-peer (P2P) services on one's small home/office network? In searching Server Fault I wasn't able to find a question that served as a rallying point for the best technical ideas on this. The existing questions are all about specific situations, and the dominant answers are social/legal in nature. Those are valid approaches, but a purely technical discussion would be useful to a lot of people, I suspect. Let's assume that you don't have access to the machines on the network. With encryption use increasing in P2P traffic, it seems like stateful packet inspection is becoming a less workable solution. One idea that seems to make sense to me is simply throttling down heavy users by IP, regardless of what they're sending or receiving -- but it doesn't seem many routers support that functionality at the moment. What's your preferred method to throttle P2P/BitTorrent traffic? My apologies if this is a dupe.

• SonicWall HA "gotchas"?

  - by Mark Henderson

  We're looking to move away from PFSense and CARP to a pair of SonicWall NSA 24001 configured in Active/Passive for High Availability. I've never dealt with SonicWall before, so is there anything I should know that their sales guy won't tell me? I'm aware that they had an issue with a lot of their devices shutting down connectivity because of a licensing fault, and they have an overtly complex management GUI (on the older devices at least), but are there any other big "gotchas" that I need to be aware of before committing a not insubstantial amount of money towards these devices? 1If you're outside the US, the SonicWall global sites suck balls. Use the US site for all your product research, and then use your local site when you're after local information.

• Switching PHP to FastCGI from mod_php broke AMFPHP

  - by wezzy

  Hi, i've just switched my debian server from mod_php to fastcgi following this tutorial everything goes right but now i've found that one of the hosted application that using AMFPHP for flash remoting is broken. I'm trying to understand what's happend. Looking at it with FireBug and FireAMF it seems that the responses has a content but the Flash callbacks never get called and if i try to open the service browser it displays this error: (mx.rpc::Fault)#0 errorID = 0 faultCode = "Client.Error.RequestTimeout" faultDetail = "The request timeout for the sent message was reached without receiving a response from the server." faultString = "Request timed out" message = "faultCode:Client.Error.RequestTimeout faultString:'Request timed out' faultDetail:'The request timeout for the sent message was reached without receiving a response from the server.'" name = "Error" rootCause = (null) It's strange it seems that the server takes a long time to responde, then (in the service browser) flash made a new call to the server and the old one get a response. Some problem with sessions ? Really no idea ....

• Windows 2008 VPS always crashes when out of disk space

  - by Pickels

  Hello, I am renting a Windows server 2008 dc SP2 VPS for hosting my Asp.Net projects. Now for the second time this month my VPS ran out of disk space. The first time it was a log file that got to big and yesterday it was my mistake for uploading a website without noticing the lack of space on my VPS. Now the side effect this has is that my VPS corrupts some files when trying to write them. Last time it was Plesk that stopped working yesterday it was IIS. So I was wondering is this normal behavior? I called my service provider to ask if they could restore a back-up and to ask if this is normal and they ensured me it was. I am not trying to blame them and I know it's mostly my fault for not monitoring my VPS better or for not setting better defaults.
