• Oracle Logical Standby redo generation

  - by DCookie

  Oracle 10.2.0.4 database with a logical standby on Win2K3. Recently a rather large delete operation was carried out on the production instance. I'm experiencing difficulty with the logical standby, in that it gets a couple of hundred (58M size) archive logs into the operation and the apply process fails with an out-of-memory error. Unfortunately, every time it fails it has to restart the apply from the beginning of the transaction. This is taking a couple of days each time. Anyway, in trying to resolve this problem, I've noticed that each archive log from the production system generates 5 or 6 log switches on the standby. I don't understand why this should be. Anyone have any ideas? A related question that I've not found the answer for: does anyone know if the logical standby must be running in archivelog mode? I really don't have a need to keep the logs.

• Configure GNU screen so that it stores command histories in files

  - by user65950

  I would like to configure GNU screen such that it stores the command histories of all the different windows in different files. I know by default GNU screen does not store the command histories (of its different windows) in a file at all (it stores them in memory instead), but it might be possible to tell it to store them in files instead? The different command history files should have the names <session>.<window>.history, or similar. Does anyone have an idea how to do that? (Just to be clear, I want each GNU screen window to write a different file. I like that each window has a different history, and I typically run different types of commands in the different windows.)

• How to diagnose a Windows XP hard crash

  - by Jon

  I have a 64-bit Windows XP machine which has hard crashed several times today. The symptoms are that the screen just goes blank, then the reboot cycle starts. There is no blue screen and even though it is switched on, no crash dump file is created. On all occasions it has happened during a period of high CPU/memory activity. I have run a full Dell diagnostics with no failures. Any ideas how to track this down further? Thanks.

• Optimal Instance Size for EC2 Sharepoint Server

  - by Rob Wilkerson

  I'm surprised that I can't find any info about this, but I'm not a Windows admin and just a novice EC2 user. I have a client who wants to stand up a Sharepoint server on EC2 for internal use. The team is small (10-20) folks and traffic will be light. Mostly, the client is looking for one place to store documents (and revisions of documents) while making access easy for authenticated users anywhere in the world. They've settled on Sharepoint and have other EC2 instances so that seems like the natural fit, but I'm trying to figure out what to recommend for them. I'm currently thinking about a Medium instance. I'm afraid to go smaller because I think Windows would need a fair amount of memory just to run, but I'm very open to suggestions. Any advice would be much appreciated. I expect that the storage itself would happen in an EBS mount, but again, suggestions welcome. Thanks for your input.

• Solution to Manage and Monitor (Ubuntu) Machines

  - by Elmar Weber

  I'm looking for a tool like Canonical (system management and monitoring for Ubuntu) that is Open Source and free. The goal is to manage a dozen or so KVM machines for private testing purposes. I know of puppet and munin or RHQ as separate tools to manage and monitor, but I'd prefer something integrated. Any tips? Basic requirements would be: system package management and update (individual selection for each managed node) configuration of basic system services (Users, NFS, cron, ideally also Apache) monitoring (charting of system resources, disk, io, memory, etc) and alerting, ideally a default configuration with sensible values for alerts

• Windows7 + Dell D830 = frequent blue screens

  - by Mulone

  I'm using Windows 7 on a Dell laptop (Latitude D380). The laptop used to be incredibly stable on Windows XP, but now I experience frequent blue screens (with a message saying "MEMORY DUMP") when I open a lot of applications concurrently. Is there a way to diagnose the issue and track it down? It could be some incompatible drivers or application. I checked the folder C:\Windows\Minidump and I found some files. THen I tried to open them and they disappeared. Any hints?

• JFFS2 poor mount performance

  - by Marcin Polkowski

  I run multiple ARM boards with Debian Linux installed. Board is equipped with 512 MB of NAND memory. I've observed that after ~3 months of continuous run booting time increased significantly - it takes over 3 minutes to mount filesystem (JFFS2). System was using about 35% of available storage so I’ve removed unnecessary files (got to ~18%) but this didn't change anything. Then I realized that my software produces directories that are left empty so I’ve removed ~500 empty and unnecessary dirs. This didn’t help either. After system is started I see JFFS2 garbage collector (jffs2_gcd_mtd4) running and occupying over 90% of CPU. Now my question: is there a way to „optimize” JFFS2 filesystem for better performance - faster booting (my system have limited timid to boot up)? It would be great if this optimization could be done remotely - I have no physical access to boards.

• Painless way of consolidating files across multiple machines/OSes

  - by 5arx

  Just bought a NAS. So I thought I'd get all our photos, media files and pdfs consolidated, de-duplicated, de-junked and virus-checked and stick them all on it. We have 3 laptops, one running Windows, the others OSX. We have a file server running Windows - it was the result of an earlier attempt at a networked fileserver - and a Mac Pro that is also kind of a server (previous attempts at this job have resulted in most of our stuff being on it). Also memory cards/sticks, cd backups and so on. I would be grateful if anyone could suggest a strategy or, ideally, tool(s) I could use to solve this problem. It is probably no more than one or two terabytes of data in total, but I can imagine that going through it all manually, file-by-file may well drive me insane.

• Problem with running a program from flashdrive

  - by rajivpradeep

  I have a USB drive with two partitions in it, one hidden and one normal. I have an application which swaps the memory and runs the flash application in hidden zone. The problem is that the application works fine on Windows 7 and when run on Win XP, it swaps the partitions but doesn't run the flash applications but just keeps running in the background. I can see it in task manager. But, when I copy the application to desktop and run, it runs with no glitch. I was facing the same problem on Win 7 too, but it was running as required when I ran it using "Run in XP mode" and then I applied a SHIM and is running since then as required. The application is built using VC++ 2008. What might be the problem?

• How to version large binary files?

  - by Walter White

  I run Windows XP inside a virtual machine for some tasks. I attempted to use git to version the image for virtual box; however, it is about 6GB after all the service packs. I only have 6GB of ram and git bombs out saying it is out of memory. I would basically like to have snapshots of Windows so that I can simply blow away an image and start anew when I want to. I like to have something I can rollback to in the event that an upgrade doesn't work so I would prefer to use version control or snapshots if the filesystem supports it. Any ideas on what tools I can use to do that?

• Tomcat access logs - are failed requests included?

  - by Maxim Eliseev

  We have a RESTful web service (Java, hosted in Tomcat on Ubuntu on Amazon EC2). From time to time it fails (not every week). When it fails, Java CPU consumption goes to 100% and it takes all available memory. It does not finish by itself. I have to restart the server. There is nothing suspicious in Tomcat access logs. I guess one of our users could submit a very "heavy" request which brought the server down. Is it possible this request is not in Tomcat logs since it never finished?

• Ubuntu/Linux version recommendation for HP dv6 3122TX?

  - by sanjayav

  I purchased a HP dv6 3122TX recently and after installing Ubuntu 10.10 64 bit I ran into multiple issues like, The wireless driver is not supported by Uubntu. (1) [The driver is RaLink RT3090 ] The ethernet stopped working sometimes for no reason [The driver is Realtek RTL8111/8168B ] "Corrupted low memory at ..." issue which is described as a kernel bug in Ubuntu support forums. (It started to take me to a terminal instead of the GUI and couldn't start x server after that) As I'm not an expert Ubuntu user I got fed up of all these issue and got back to Windows 7. But I need an Ubuntu installation up and running for my development work. What are your suggestions about a reasonable Ubuntu version that I should try? Or a different Linux variation? Should I stick to a 32-bit version? It'd be great anyone can give some advice on this issue.

• txt file descriptor in lsof

  - by wfaulk

  In my experience, files that have the file descriptor of txt in lsof output are the executable file itself and shared objects. The lsof man page says that it means "program text (code and data)". While debugging a problem, I found a large number of data files (specifically, ElasticSearch database index files) that lsof reported as txt. These are definitely not executable files. The process was ElasticSearch itself, which is a java process, if that helps point someone in the right direction. I want to understand how this process is opening and using these files that gets it to be reported in this way. I'm trying to understand some memory utilization, and I suspect that these open files are related to some metrics I'm seeing in some way. The system is Solaris 10 x86.

• how to disable moving down on Enter key in Excel 2007?

  - by earlyadopter

  There used to be a check-box in preferences in Excel 2003 to disable moving down on Enter key after you edited a cell. Where could I find that setting in Excel 2007? <whining on>It drives me insane how microsoft trashes users skills and "fingers" memory to make what their new users may be will find easier. What about us, using these products for ten years?<whining off> I want to control moving around with arrow keys, and Enter to only return me from the cell editing mode to navigation, not moving down. I'm not in a data entry business!! I'm analyzing data, editing just few cells time-to-time.

• windows VPS running apache and mysql, php scripts running slow.. but cpu usage is 1-3%..

  - by Roeland

  So every night I run some cron jobs. It requires probably about 20 min to process all the records. I gather the script does something like 10,000 sql queries. I figure this task was just that intense and needs time to complete, but I looked at CPU and memory usage, and it is super low. Cpu usage is between 1-3% and once in a while will bounce to 50ish for 2-3 seconds. This VPS is running windows 2003 server with Apache and MySQL. Does this sound right?

• How do I pick a motherboard?

  - by EpsilonVector

  When building your own computer one part was always a mystery to me: the motherboard. Picking a CPU/GPU/memory is easy- you just figure out where the various chips are in the low end to high end scale, do a little market research on what current games demand, and pick the parts from their respective continuums of low-to-high-end models. A mother board is more complicated though. Its features are not as obvious as "this motherboard is faster than that motherboard". Now you need to deal with part compatibilities, bus speeds, maybe power management stuff, etc. I'm interested in a short guide for selecting a motherboard, especially- what pitfalls to avoid (for example, can bus speed become a bottleneck?). To clarify: I'm not looking for motherboard recommendations. I'm looking for guidance regarding how to evaluate the fitness of a motherboard given the rest of the computer parts.

• Rolling desktop recorder?

  - by lance

  I want a piece of software that will constantly record what I'm doing on my desktop, discarding footage that's over [30] seconds old. Its recording would be a rolling one. The idea is that I can somehow hit a button and see "what just happened". I don't want to have to babysit it. That is, I don't want a piece of software designed for screencasting (which I'm not trying to do). My bias against that is based on my (maybe incorrect?) assumption that I'd regularly have to start/stop the recording throughout the day. The idea is that this piece of software would consume fewer resources (than a screencast recorder) on my box, as it's only keeping a very limited amount of footage in memory (and low quality would even be acceptable), because it's discarding frames fairly quickly after they're captured. Where can I find a piece of software with features like this?

• server performance metrics report and practicality

  - by Anjesh

  I have a need of preparing web server (apache-php) performance report containing important metrics like CPU usage, disk io, memory usage on user basis. Couple of domains are hosted in the same server and they run from separate users using fcgi. The reason being sometimes some hosted applications take lots of cpu usage, making the server slow for other applications (running as separate users). i am planning to develop scripts for this, as i can't seem to find any simple utilities for this purpose. This script will take snapshots of the user wise metrics at defined periods say 15 minutes and record it. Any abnormalities will be reported via emails. How practical is that? also would be interesting to know what else need to be recorded.

• Apache crashing at random intervals. Can not find a reason in log files

  - by Nick Downton

  We are having an issue with a VPS running plesk 9.5 on ubuntu 8.04 At seemingly random intervals Apache will disappear and needs to be started manually. I have checked the apache error log, /var/log/messages, individual virtual host apache error files and cannot find anything that coincides with the time of the failure. dmesg is empty which is a bit odd. We have also had the psa service go down for no apparent reason but apache stay up. I'm at a loss to diagnose this really because all the log files I can find do not point to any issues. Are there any others I can look at? Memory usage sits at about 55% (out of 400mb) and it isn't a particularly high trafficed server. Any pointers as to where else I can find out what is going on would be very much appreciated. Nick

• Remove postgres from Mac - installed in /usr/local/, can I just delete files?

  - by Richard

  I want to completely uninstall postgres and start from scratch - the version I have is refusing to work with PostGIS 2.0. I have read other answers on how to do this, but none of them seem to fit the way postgres is set up on this machine. I'm not sure postgres was originally installed on this machine - it wasn't via brew or Postgres.app or the EnterpriseDB installer - but it seems to be living in /usr/local: $ which psql /usr/local/pgsql-9.1/bin/psql The postgres binary itself is in /usr/local/var/postgres/. How can I kill it forever? Can I simply go to /usr/local and do rm -rf pgsql-9.1, and the same in /usr/local/var, and make sure there are no paths in my profile file? Or is there more to it than that? From memory I think I'll need to delete the database files too somehow. Thanks for the help.

• Why does my CPU Usage reach 100% too often?

  - by deathlock

  I'm using a dual-core processor and often see my CPU usage reaches 100%. I realize this may happen if I'm running too much applications, so when I know the computer starts to run slowly, I start to close my applications. I usually run 4-5 applications simultaneously. Usually those are: web browser (Google Chrome), Adobe Photoshop, Notepad++, XAMPP, and Windows Task Manager. Usually I close tabs in my Chrome first, because I often browse the net with about 20 tabs/4 windows open, so I presume that would take much memory (bad habit, I know). But even after closing Chrome's tabs or closing other applications, my CPU Usage often stays at high percentage - 72% at best, 100% at worst. I check the Processes tab on Windows Task Manager and usually found the System, System Idle Process, or services.exe taking the highest CPU process (could reach 60). Why is this happening? And is there any solution? EDIT I have T2250 @ 1,73 Ghz and 2.5 GB RAM

• VMware ESX 3.5 Host Health shown as unknown

  - by dunxd

  I have an ESX 3.5 update 5 cluster of five host servers, all fully patched as of this Friday. Today I noticed that one of the servers has the Hardware Health status as unknown in Virtual Center Infrastructure Client. When I look at the Health Status view under configuration for that host, all the items are status Unknown. The server is exactly the same configuration as the others - same model (HP DL360 G5), memory, NICs etc. I have tried restarting the management service with service mgmt-vmware restart but this has not resolved the issue. Asides from this, I am not seeing any issues with the cluster - however, I hate having a blind spot like this. Any ideas?

• Firefox Task Manager [closed]

  - by chris Frisina

  CLOSED!??? I SPECIFICALLY said for OSX, and the previousquestionprovides answers for Windows and other addons are for older versions of FF, or do not answer the question. This is a specific question for OSX. Chrome has a built in task manager under "Tools" to look at the process within Chrome, extremely beneficial in locating a stuck page. What is the similar feature in firefox? I need to identify what is causing it to run slowly, and the addons they suggested dont work for OSX or are outdated, and Chrome's about:memory isn't recognizing FF FF Version 17.0, OSX version 10.8.2 Build 12C3006 How to get to Task Manager: Task Manager: THIS IS NOT A DUPLICATE OF: Possible Duplicate: “Task Manager” addon for Firefox?
