  • Determine the Ports reserved and what service reserved them in Windows XP/2003

    - by bogha
    hi, this question is always rise. How can i know what ports are currently reserved in windows XP/2003 and what service had reserved them. for example when i want to install Apache, default port will be 80, but sometimes the Server will have IIS installed on the same port. so i want to know the way to check the ports and what services had reserved them and also if there is a way to re assign those ports to different services. thank you

  • Hardware reserved memory issue

    - by Robert Koritnik
    I've seen lots of folks having problem with hardware reserved memory issue in Windows 7/Server 2008 R2. I have it myself but not as huge as others have. Problem description When you install Windows 7 (or its bigger brother Windows Server 2008 R2) your memory may not be fully utilised. If you look at Task Manager > Performance Tab > Resource Monitor > Memory Tab And scroll to the bottom of the list you will see a graphical representation of your memory. Some of it may be hardware reserved. Previous Windows versions didn't have this problem. System was able to utilise all memory available. Question Is there any solution to lower/remove hardware reserved memory? Sidenote I tried installing 32 and 64 bit versions but to no avail. I also tried both Windows: 7 and Server 2008 R2. But always get the same amount reserved by HW. On previous Windows versions I had more memory available because I'm simultaneously running 2 VMs on host (so three machines all together). And my memory peaks much higher now as it did on older versions.

  • Amazon EC2 Reserved Instances: "Heavy Utilization" clarification

    - by gravyface
    Should be another easy one here, but I need clarification on what they define as "heavy utilization" for Reserved Instance types. From their Website: Heavy Utilization RIs – Heavy Utilization RIs offer the most absolute savings of any Reserved Instance type. They’re most appropriate for steady-state workloads where you’re willing to commit to always running these instances in exchange for our lowest hourly usage fee. With this RI, you pay a little higher upfront payment than Medium Utilization RIs, a significantly lower hourly usage fee, and you’re charged that lower hourly rate for every hour in the Reserved Instance term you purchase. Using Heavy Utilization RIs, you can save up to 41% for a 1-year term and 58% for a 3-year term vs. running On-Demand Instances. If you’re trying to find a break-even utilization, you’re economically advantaged using Heavy Utilization RIs (vs. On-Demand Instances) if you plan to use your instance more than 43% of a 1-year term or 79% of a 3-year term. I'm assuming that, if I'm planning on running a 24/7 Web Server, then regardless of how many resources I consume (bandwidth, cpu cycles, memory), I would want to go with a Heavy Utilization Reserved Instance? This one Web Server in particular will likely barely budge the cpu, but it needs to be up and running 24/7. Not 100% on what they're defining as "heavy".

  • System reserved

    - by arun sidharth
    I have a HP laptop. I upgraded to windows 7 ultimate from home basic. Now I'm trying to upgrade to Windows 8 but when I do I get a message saying not enough system partition. So I opened the disk manager and increased the size of system reserved partition and it was of no use I still got the same error. Then I unfortunately deleted the 100MB system reserved partition by right clicking it and clicking format in the disk manager! Now I am not able to boot any CD's from the startup including OS and recovery CD. Whenever I press esc it always goes to the login screen and it doesn't say anything about the boot from CD option. Now I could not even use my recovery CD. I have 3 questions: Is it necesseary to create a system reserved partition if so how to create it? How to use my recovery cd How to install win 8

  • Probelm with String.split() in java

    - by Matt
    What I am trying to do is read a .java file, and pick out all of the identifiers and store them in a list. My problem is with the .split() method. If you run this code the way it is, you will get ArrayOutOfBounds, but if you change the delimiter from "." to anything else, the code works. But I need to lines parsed by "." so is there another way I could accomplish this? import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; import java.util.*; public class MyHash { private static String[] reserved = new String[100]; private static List list = new LinkedList(); private static List list2 = new LinkedList(); public static void main (String args[]){ Hashtable hashtable = new Hashtable(997); makeReserved(); readFile(); String line; ListIterator itr = list.listIterator(); int listIndex = 0; while (listIndex < list.size()) { if (itr.hasNext()){ line = itr.next().toString(); //PROBLEM IS HERE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • Rails reserved words and convention

    - by PatrickLightning
    After having spent a lot of time researching Rails reserved words and implementing, I still have a few questions regarding use. In my example here, I'll consider the reserved word 'time'. Let's say I want to create a class 'Timepiece'. Is it not recommended to use 'timepiece' because the name begins with 'time'? Would it be recommended to use 'time_piece' or to avoid inserting the reserved word at all? My question here is also about use of the exact reserved word within the class like that. Thank you.

  • Need alternative field names for these reserved words

    - by MattSlay
    “type” and “class” are likely reserved or problematic words in C# and/or Ruby, two languages I may use to program against my new database schema in the future. So, in order to avoid potential conflicts with those languages, I’m looking for alternative names for these field names in my tables. In this case, it is from my Machines table, where I have: “class” field (values would be something like “manual” or “computerized”) and “type” field (values would be “lathe” or “mill”) I could call the fields “machineclass” and “machinetype”, but that is inconsistent with naming scheme in the rest of my schema (meaning, I do not re-use the table name in the field… For instance, I use Machine.name, not Machine.machinename) Any thought on this madness?

  • Reserved Memory Addresses?

    - by Nate
    Is there a list of reserved memory addresses out there - a list of addresses that the memory of a user-space program could never be allocated to? I realize this is most likely per-OS or per-architecture, but I was hoping someone might know some of the more common OSes and Arches. I could only dig one up for a few versions of windows: for windows NT,2k and XP that would be: 0x00000000 - 0x0000ffff - lowest page is protected to simplify debugging 0x00001000 - 0x7ffeffff - memory area for your application 0x7fff0000 - 0x7fffffff - protected area to keep memory-functions from damaging the following part 0x80000000 - 0xffffffff - memory where the system including drivers and so on is located Anyone know about for Linux, or BSD (or anything else, for that matter)?

  • How to Refresh or Reset Windows 8 without the System Reserved partition?

    - by Karan
    The article Refresh and reset your PC mentions exactly what happens during the refresh and reset operations in Windows 8: Refresh The PC boots into Windows RE. Windows RE scans the hard drive for your data, settings, and apps, and puts them aside (on the same drive). Windows RE installs a fresh copy of Windows. Windows RE restores the data, settings, and apps it has set aside into the newly installed copy of Windows. The PC restarts into the newly installed copy of Windows. Reset The PC boots into the Windows Recovery Environment (Windows RE). Windows RE erases and formats the hard drive partitions on which Windows and personal data reside. Windows RE installs a fresh copy of Windows. The PC restarts into the newly installed copy of Windows. It is my understanding that Windows RE (Recovery Environment) is included as part of the System Reserved partition created by default on the first hard disk. The size of this partition has gone up to 350 MB from the 100 MB it used to be in Vista/Windows 7, no doubt as a result of adding these features. Now we have already discussed how to skip the creation of this System Reserved partition during Setup. Basically, the same techniques that used to work with Windows 7 work with Windows 8 as well. What I want to know is, what will be the exact repercussions of not having the System Reserved partition in place? I assume Troubleshoot / Advanced options should still be available as before: But what about the Troubleshoot menu itself? Will the Refresh and Reset options disappear? Will they remain but be unavailable? Or possibly they will throw an error if selected? Also, will it be possible to access and successfully execute these options if installation media is available? Anything else that might be affected?

  • Proper Imaging Procedures to Restore and Deploy Image with Separate System Reserved Partition

    - by alharaka
    UPDATE: As per my experience here, no one responded. If I do not hear back from TechNet forum members about it, I will post a bounty here, if it makes a difference. I have banged my head against a wall for what seems like all week. I am going to explain my simple procedure, and how none of it, absolutely none, seems to work afterword despite few alternatives and everyone on the internet telling assuming this is how to do it. Diskpart Commands to Create FS Structure REM Select the disk targeted for deployment. REM REM NOTE: Usually disk 0, but drive failure can make it external USB REM media. This will erase the drive regardless! select disk 0 REM Remove previous formatting. clean REM Create System Reserved partition bootloader and files. create partition primary size=100 REM Format the volume format fs=ntfs label="System Reserved" quick override noerr REM Assign the System Reserved partition the D: mount for now assign letter=C REM The main system partition, size not specified to occupy whole drive. create partition primary REM Format the volume format fs=ntfs quick override noerr REM Assign the OS partition the D: mount for now assign letter=D REM Make this the active/bootable partition. sel disk 0 sel partition 1 active REM Close out the diskpart session. exit Now, I thought this was madness, but it turns out the System Reserved partition and standard "System Partition" (C:, commonly both the boot and system volumes where you find the Windows directory AND the bootmgr/ntldr hardware files, this is where Windows 7 diverges) as mounted in the Windows PE session where I run these commands do not matter. See reference here. Since this needs to be BitLocker-ready, enter this crappy System Reserved partition that is separate 100MB of awesome that goes before the regular boot volume. I do this, then I proceed to the next step. Deploy System Reserved and Normal System Images REM C is still the "System Reserved Partition", and the image is just like it sounds. imagex /apply G:\images\systemreserved.wim 1 C: REM D is now what will be the C: system partition on reboot, supposedly. imagex /apply G:\images\testimage.wim 1 D: Reboot the system Now, the images I just captured should look good. This is not even sysprepped, but reapplying the same fscking image I prepared on the same reference workstation hours before. Problem is I get 0xc000000e could not detect the accessible boot device \Windows\system32\winload.exe or different kinds of nonsense revolving around being able to find the boot volume with all the right files. I try different variations of things, now none of them work. I tried repairs with bcdboot, with a fresh System Reserved partition or not, bootrec, and maually editing the damn BCD store with bcdedit. I tried finalizing the above process with and without bootsect /nt60 C: /force. I need to wrap up and automate this procedure. What am I doing wrong that does not make the image happy, but really just miserable.

  • Intentional misspellings to avoid reserved words

    - by Renesis
    I often see code that include intentional misspellings of common words that for better or worse have become reserved words: klass or clazz for class: Class clazz = ThisClass.class kount for count in SQL: count(*) AS kount Personally I find this decreases readability. In my own practice I haven't found too many cases where a better name couldn't have been used — itemClass or recordTotal. However, it's so common that I can't help but wonder if I'm the only one? Anyone have any advice or even better, quoted recommendations from well-respected programmers on this practice?

  • Are there any reserved words in SQLite?

    - by DanM
    Three questions about reserved words: Are there any reserved words in SQLite? If so, what are they? If there are reserved words, is the correct syntax for using one of them as a column or table name still to surround it with brackets? E.g., [User] or [Name]? Are there any implications with using words that are reserved in other flavors of SQL (e.g., SQLServer) but not reserved in SQLite when using ADO.NET to query a SQLite database?

  • System and active partitions, and "System Reserved"

    - by a2h
    Upon trying a 3rd party bootloader (loaded from a disc), and trying to boot into my partition "Windows 7", I get "BOOTMGR is missing, Press Ctrl+Alt+Del to restart". But ordinary booting works fine. So I'm thinking, that perhaps it's because of my partitions. Upon opening "Disk Management", I notice out of my partitions, "System Reserved", "Windows 7" and "Documents", "Documents" is marked as both System and Active. I've looked into what an active partition is, and what "System Reserved" is for, so I'm thinking - should I mark "System Reserved" as active? The problem is, all images of Disk Management depicting "System Reserved" have it with both System and Active attributes, and so I am unsure on what to do, and also on why my "Documents" partition even is marked with System and Active.

  • Can't boot after Deleted System Reserved Partition

    - by mauris
    I accidentally deleted the System Reserved Partition and now I can no longer boot into Windows 7. The installation of Windows and all my files still exists in the partition, but without the System Reserved Partition I can no longer boot. After I deleted the System Reserved Partition I moved left the primary partition to fill the space. Is there any way I can "reinstall" that System Reserved Partition and the boot files? PS: I only have Windows 7 installed. No dual-boot nothing.

  • Where can I find a list of reserved words for Oracle fulltext search?

    - by Tyronomo
    I've a client testing the full text (example below) search on a new Oracle UCM site. The random text string they chose to test was 'test only'. Which failed; from my testing it seems 'only' is a reserved word, as it is never returned from a full text search (it is returned from metadata searches). I've spent the morning searching oracle.com and found this which seems pretty comprehensive, yet does not have 'only'. So my question is thus, is 'only' a reserved word. Where can I find a complete list of reserved words for Oracle full text search (10g)? Full text search string example; (<ftx>test only</ftx>)

  • window 7 hardware reserved ram

    - by alex
    Hi, I have Windows 7 64bit, 8gb ram and 1152mb is hardware reserved which leaves me with 7039mb of physical memory available as I can see on the task manager. What is the advantage or disadvantage of keeping it this way? If I disable it from the MSCONFIG, the hardware reserved comes down to 1mb. Well, which way I should keep it for best performance in all meanings considering that nowdays, 8gb is still a lot. Could someone explain the easy way please?

  • AMQP 'connection.open' reserved parameters

    - by jldupont
    I am writing an AMQP Client Library in Erlang. For the 'connection.open' method, there are 2 reserved parameters "documented" in AMQP 0.9.1 out of a total of 3. When I send the method in question without the "reserved parameters", I get "unable to decode method" in the error log. What should I be sending as value for those "reserved parameters" ?? Update: It seems the server still expects some parameters even if the parameters are deprecated (see source code for code generator).

  • Half of installed RAM is hardware reserved

    - by user968270
    After a rather arduous and convoluted series of problems that left me without a desktop for ~80 days, I've finally got the thing up and running, having replaced the power supply, motherboard, graphics card and CPU. Now, however, I'm experiencing the 'hardware reserved RAM' issue. Perhaps this is the exhaustion talking, but looking at the question that tends to get pointed to when this kind of topic gets locked as a duplicate hasn't helped. I have 16 GB of RAM installed in an MSi 970A-G46, which is spec'd for up to 32 GB of RAM. The BIOS recognizes that I have 16 GB installed, and the resource monitor also shows the whole 16 GB, only it shows 8 GB as hardware reserved. I've seen suggestions that it's an OS issue, but the particular installation of Windows 7 (64-bit) which I'm running on my boot drive is the same as the one that could actually access the 16 GB in my previous motherboard (MSi 870A-G54). I've updated my BIOS using the MSi Live Update tool and restarted the machine with no effect, and I cannot seem to locate any 'Memory Remapping' option as I've seen mentioned. I've physically swapped the RAM between the slots to no effect. I've unchecked the Maximum Memory box in the msconfig Boot tab's advanced options, also to no effect. These are my system's basic specifications OS: Windows 7 Home Premium (64-Bit) Motherboard: MSi 970A-G46 CPU: AMD FX-8150 Graphics Card: XFX Radeon HD 6870 Boot Drive: OCZ Agility 3 Storage Drive: Samsung Spinpoint F3 ST1000DM005/HD103SJ 1TB PSU: Thermaltake TR-2 TR600 600W ATX12V v2.3

  • System Reserved partition no longer marked as System

    - by Mark
    I recently posted a question to Super User about accidentally marking my external HDD's partition as Active and how I could undo my accidental mistake. I followed the instructions provided and they worked fine. This involved some command line magic and from what I understand, I did not have to really do this, but I just wanted to get things back to how they were originally. After making the fix things went back to normal in disk management. After I restarted my computer though i had an issue: BOOTMGR is missing Press Ctrl+Alt+Del to restart Rugh roh! I brought my laptop to work so I could search for a solution on my work computer and I found a nice guide on fixing the issue. To summarize the instructions, I had to reboot with my Windows 7 install disc and click the Repair button. Once there I could then repair the start-up options. One of the commenters on the site claimed you need to do this twice, as the first time the "repair" doesn't actually fix it. I found this to be true as well. I tried to repair it and it did some work, then rebooted. I then got the same error again. I booted from the CD again and repaired the start-up options then after this second time Windows started to boot up. Before the restart I got a nice info window telling me that it did make repairs to the boot info (this was promising). I've been using Windows 7 for a few days now with no problem, but I just recently noticed that I now can see the System Reserved partition in Computer: (click for full size) I immediately went to disk management to see what was up. I noticed that my System Reserved partition is no longer marked as System and instead I believe the repair operation made my C: drive the system partition. I'm not fully aware of what the System partition really is but I briefly read that its a Windows 7 thing that gets created on install of Win7 that writes some BitLocker encryption stuff to a isolated partition as well as some boot files. (click for full size) How can I undo this and make the System Partition marked as System instead of my OS C: partition? How can I make it so that I don't see this partition in Computer (I believe fixing #1 will fix this) What are the implications of what the current state is and the fact that I can now browse into this new partition? Thanks in advance.

  • Control SQL Server CLR Reserved Memory

    - by Ryu
    I've recently enabled CLR on my 64 bit SQL Server 2005 machine for usage of about 3 procs. When I run the following query to gather some info on memory usage... select single_pages_kb+ multi_pages_kb + virtual_memory_committed_kb as TotalMemoryUsage, virtual_memory_reserved_kb from sys.dm_os_memory_clerks where type = 'MEMORYCLERK_SQLCLR' I get 129 mb MemoryUsage and 6.3 gb Virtual Memory Reserved The total memory of the machine is 21 gig. What does reserved virtual memory mean exactly and how can I control the size that is allocated? 6 gig is overkill for what we're doing and the memory would be much better utilized by the sproc cache. I'm concerned this reserved memory will cause swapping to the page file. Please help me take back control of the memory! Thanks

  • What are the IPv6 Public and Private and Reserved ranges

    - by vipin raj
    I just want to know what are all the public IPv6 ranges which ISPs or other users can use? Also need a list of addresses which can be used in private networks and also the list of addresses which never can be used in any network. I have been searching through different web sites. But none gives a reliable answer. Actually we are developing an application which allows user to plan their IP address(create supernets, subnets, hosts, assign host to ports etc). So my application should be able to distinguish between all kinds of address ranges, whether it is reserved, public, private, multicast etc
