• What is Google Docs' SLA?

  - by Walter White

  Hi all, I am evaluating online storage and for me, that means either Amazon S3 or Google Docs. Amazon very clearly posts there reliability and SLA: http://aws.amazon.com/s3/#protecting Their rates are obviously higher than Google's, but it is really hard to compare without having an SLA. Does anyone know what Google's commitment is for reliability? Is it 99.99% for data, is there anyway to make that more durable? I have to ask too, wouldn't google docs at least be inheritently more reliable than a hard drive? Thanks, Walter

• Why Both 8GB USB Flash Drives Have Different Integrities?

  - by Boris_yo

  USB 3.0 SuperTalent Express DUO 8GB recently had its partition corrupted and declared itself "write-protected" and I was told in chat by @sidran32 that this usually means that flash drive gone bad due to writing cycles limit being reached. Having this thumbdrive for over a year being used infrequently, I was in doubt and referred to SuperTalent's support. I was given recovery tool which I executed but it failed first time prompting me to reinsert it. After that, I formatted it with Windows 7 integrated format utility since recovery tool offered to do this as well which was successful. The problem as I have noticed is with integrity of SuperTalent: Compare above to SanDisk's Micro Cruzer 8GB: Am I missing something? Both thumbdrives are of 8GB and have same FAT32 file system.

• On MySQL 5.1 for Windows, why can't I assign DBA role to the "root" user?

  - by djangofan

  On MySQL 5.1 for Windows, why can't I assign DBA role to "root" user? The MySQL Workbench allows me to add all the other roles except for DBA. Also, when I "alter schema" on any table, while logged in as root, I dont see all the tabs that show me all the database properties... I only see the first tab that allows me to change collation only. What is wrong with this picture? How do i give root all priveleges? I've tried a few variations of GRANT ALL PRIVILEGES etc. from the command line but nothing works. My root account is unable to alter column names, indexes, or options of any given table that I create. I can create tables and delete them but I can't alter them.

• Severe errors in solr configuration: Error loading class

  - by James Lawruk

  Installed Solr on my Windows XP PC. Tomcat seems to be working fine. Cannot get Solr to work. I noticed the TrieDateField is declared in a file called schema.xml in the SolrHome directory. Any thoughts? The Url http://localhost:8080/solr/ returns: HTTP Status 500 - Severe errors in solr configuration. Check your log files for more detailed information on what may be wrong. If you want solr to continue after configuration errors, change: false in null ------------------------------------------------------------- org.apache.solr.common.SolrException: Unknown fieldtype 'date' specified on field updated Here is an excerpt from the catalina log file: SEVERE: org.apache.solr.common.SolrException: Error loading class 'solr.TrieDateField' at org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:273) Caused by: java.lang.ClassNotFoundException: solr.TrieDateField

• Can't uninstall SBS 2003 in sbs 2003 -> sbs 2008 migration

  - by ChrisMuench

  I'm trying to remove sbs from my sbs 2003 server. Also I'm logged in as Administrator. However When I start to go through the wizard it gives me the following error. You must be a member of the Domain Admins, Schema Admins, and Enterprise Admins group. I then did some research and found this (http://support.microsoft.com/kb/842694) and I came to the point where it says to delete the server from Sites and Services. However when I clicked delete it wanted me to dcpromo the box first. However I have read you have to uninstall exchange first and then dcpromo it to remove AD. Any ideas?

I can log into iSeries Navigator, navigate to schema functions permissions and change the permission for public from Exclude to All. bam it works. How do I grant permission to all, either in the CREATE FUNCTION or after?

• How to backup/restore excluding filestream varbinary in SQL Server 2008?

  - by fdierre

  There is an application used in a production site that uses SQL Server 2008 as its DBMS. The database schema uses Filestream Varbinary to save binary data on the filesystem instead of directly into the DB tables. The point is that now and then it would be useful to copy the production database on development machines, mostly for doing troubleshooting. The database is too big for comfortably moving it around, but it would be ok if it could be moved leaving out the filestream varbinary fields. In other words, I am trying to make an "imperfect" copy of a database: i.e., on the destination database, it is ok to have NULL values instead of the varbinary. Is this possible? I tried looking for the feature on the SQL Server Management studio and did a backup that excludes the filegroup containing the filestream varbinary, but I cannot restore: MSSMS complains that the restore cannot be done because the backup is incomplete (of course). Is it possible to achieve what I am trying to do in some way?

• Make server unavailable gracefully using Powershell in ARR

  - by Carl Bergquist

  We are using ARR as reverse proxy and I would like to make a server unavailable for various reasons. How can this be done using Powershell? Edit 1: I found this http://blogs.iis.net/anilr/archive/2009/11/09/using-arr-config-extensibility-to-gracefully-stop-server.aspx tutorial for using JScript. But I'm not able to translate it to powershell. Edit 2: Using the Set-WebConfigurationProperty in WebAdministration module I'm able to changes settings for a server. I found SetState in %windir%\system32\inetsrv\config\schema\arr_schema.xml but I don't know how to invoke that method.

• Hyper-V performance comparisons vs physical client?

  - by rwmnau

  Are there any comparisons between Hyper-V client machines and their physical equivalent? I've looked around and can find 4000 articles about improving Hyper-V performance, but I can't find any that actually do a side-by-side comparison or give benchmarking numbers. Ideally, I'm interested in a comparison of CPU, memory, disk, and graphics performance between something like the following: Some powerful workstation (with plenty of RAM) with Windows 7 installed on it directly Same exact worksation with Hyper-V Server 2008 R2 (the bare Server role) and a full-screen Windows 7 client machine Virtual Server 2005 had performance that didn't compare at all with actual hardware, but with the advances in CPU and hardware-level virtualization, has performance improved significantly? How obvious would it be to a user of the two above scenarios that one of them was virtualized, and does anybody know of actual benchmarking of this type?

• Create mix CDs from MP3 files

  - by Dave Jarvis

  How would you write a script (preferably for the Windows commandline) that: Examines thousands of MP3 files stored on a single drive (e.g., G:\) Randomizes the collection Populates a series of directories up to 650MB worth of songs (without exceeding 650MB) Every song is shucked exactly once (Optional) The directory size comes as close as possible to 650MB The DIR, COPY, and XCOPY commands have no explicit file size switches. A few Google searches have come up with: File size condition in DOS Cygwin and UWIN DOS File sizes It would be ideal if UNIX-like environments can be avoided. My question, then: How do you compare file (or directory) sizes using the Windows commandline?

• Migrating data from SQL Server 2000 to SQL Server 2005

  - by Muhammad Kashif Nadeem

  I have to migrate existing data which is in SQL Server 2000 to SQL Server 2005. The schema of two databases is different. For Example Locations table in SS2000 is split into two tables and has different columns. This is one time activity. After successful migration I don't need old db anymore. What is the best way to transfer data from one SQL Server to another having different schemas? I can write stored procedures to fetch data from SQL Server 2000 and insert/update tables in SQL Server 2005. What about SSIS? I don't have any experience with this and is this better to create package of SSIS because I don't need this again and need to learn it first. Thanks.

• Practical RAID Performance?

  - by wag2639

  I've always thought the following to be a general rule of thumb for RAID: RAID 0: Best performance for READ and WRITE from stripping, greatest risk RAID 1: Redundant, decent for READ (I believe it can read from different parts of a file from different hard drives), not the best for WRITE RAID 0+1 (01): combines redundancy of RAID 1 with performance of RAID 0 RAID 1+0 (10): slightly better version of RAID 0+1 RAID 5: good READ performance, bad WRITE performance, redundant IS THIS ASSUMPTION CORRECT? (and how do they compare to a JBOD setup for R/W IO performance) Are certain practical RAID setups better for different applications: gaming, video editing, database (Acccess or SQL)? I was thinking about hard disk drives but does this apply to solid state drives as well?

• How can I adapt a Dell 2001FP stand for use on newer Dell monitors?

  - by user26453

  I find myself really disappointed with how little vertical adjustment newer Dell LCD's have. I retiring a malfunctioning Dell 2001FP. The stand on the 2001FP allows over 6 inches of vertical adjustment. Compare this to my newer monitors, a 2005FP and a SW22209, both of which allow at most 2 inches of vertical adjustment. So while the Dell 2001FP monitor is shot, the stand is not. Is there anyway to fit the stand onto the SW2209 or the 2005FP? The 2001FP stand seems to have an odd plate with three tabs on the top edge. Can I replace this?

• Finding out whether files are added, changed or deleted on a FTP server

  - by futureelite7

  I've recently been given the task to migrate about 200GB of data from one dedicated server to another. As this will take a week or more, I've been taking a snapshot of the current files on the FTP server using wget's mirror feature. However, since other users will probably be uploading / changing stuff in the meantime, the snapshot that I have made will not include the most recent changes. Since I only have access to FTP on this server, I'm planning to write a script that will recursively do a FTP stat on all files in the FTP folder, and compare the directory listing against the snapshot I have locally. If there are differences in the number of files, then I know files have been added or deleted. If the modification dates have been changed, then I know the files have been changed, and should redownload those files specifically. Am I missing anything in my approach, or are there any possible improvements to this approach?

• Are Motherboards for the Acer Aspire One AOA150 Netbook Compatible with the AOA110?

  - by Mindstormscreator

  I have an Acer Aspire One ZG5 AOA110-1588 netbook, and the motherboard doesn't have a port for a SATA 2.5 inch hard drive; it only supports this slow 8GB SSD type drive. Through research I've discovered that the AOA150 motherboards do have a SATA slot, and the bottom plate of these laptops have an appropriate protrusion for the drive to fit in (for example, compare this to this). The AOA110 and AOA150 models are very similar in appearance and specs. I've even seen tutorials that involve soldering a SATA connector onto the AOA110's motherboard, essentially creating an AOA150 motherboard (right?) So, could I just swap out the motherboard in my netbook with the MBS0506001? (I'd post another link to the actual board but can't because of the spam prevention...) I assume I would also need to purchase and replace the bottom cover with a larger one and possibly get a hard drive caddy as well...? Thanks!

• What database is easy to maintain and manage in a cluster?

  - by Sanoj

  I'm looking for a database (DBMS) that is easy to scale out. I would like to have high availability so I need a multi-master cluster, where the data is replicated to two or more physical computers. I would also like to be able to start with one node (no replication), and then scale out to more nodes as needed without a reinstallation or downtime. I would like to have a DBMS that are easy to maintain and manage. It should be easy to add nodes, remove nodes, take live backup and monitor the use of resources. It doesn't have to be a relational database system, so a NoSQL is okey. And I would like to have a free version so I can test it in small scale and compare it with alternatives. What alternatives do I have?

• Modeling RBAC actors using LDAP (Core X.5xx)

  - by Tetsujin no Oni

  Mirrored from stackoverflow... When implementing an RBAC model using an LDAP store (I'm using Apache Directory 1.0.2 as a testbed), some of the actors are obviously mappable to specific objectClasses: Resources - I don't see a clear mapping for this one. applictionEntity seems only tangentially intended for this purpose Permissions - a Permission can be viewed as a single-purpose Role; obviously I'm not thinking of an LDAP permission, as they govern access to LDAP objects and attributes rather than an RBAC permission to a Resource Roles - maps fairly directly to groupOfNames or groupOfUniqueNames, right? Users - person In the past I've seen models where a Resource isn't dealt with in the directory in any fashion, and Permissions and Roles were mapped to Active Directory Groups. Is there a better way to represent these actors? How about a document discussing good mappings and intents of the schema?

• Help replacing old Windows 2003 SBS DC with a Win2008 Standard Edition DC

  - by Chris

  Objective: Trying to replace a Windows 2003 SBS domain controller with a windows server 2008 Standard Edition Domain Controller. What I did: used ADPREP. Then all user accounts and OUs are successfully replicated into the 2008 server. I have also managed to transfer all the DC roles (operations master,schema,pdc) into the Server 2008. I have also used NETDOM QUERY FSMO . It displayed that all the roles transferred to the 2008 server. Problem: When I am trying to demote the windows 2003 SBS server using DCPROMO, the message is “No other Active Directory for this domain can be contacted”. I also tried shutting down the 2003 server. Users can login into the domain but they have trouble finding SHARED folders. Can someone help me find out what I did wrong ? Need a little push in the right direction here. Thank you very much ?

• SQL Server User Mapping - Limit view of databases for a user

  - by Jaime

  Hi there, I am adding a new Login with SQL Server Authentication. I set its Server Role as public and then went into User Mapping, selecting the only database this user should have access to. I then change the Default Schema to dbo and made this user the db_owner. I then connect to the instance using the new user's credentials and I can see not only the database he should have access to but all the other attached databases. How can I limit this user to just see the database he has access to? Thanks in advance!

• Software to copy non-duplicate files from CD/DVD

  - by John22

  I have several CDs/DVDs which have partially overlapping content (the overlapping files are identical, but have different names), and some of the files are on my hard disk. I need to get the remaining unique files copied to my hard disk. I found a really good duplicate file finder, Duplicate Cleaner, which lets you select multiple folders and then finds duplicates by checksum (or file name, size, date) and is very fast, and free. It won't help me do what I want though, unless I just copied everything, and then deleted the duplicates - but I would have to do multiple cycles, as I don't have room to copy all the CDs/DVDs to my hard disk. I found a couple of file sync programs, but they don't have the compare function - the file names must match. (I tried other duplicate file finders on CNET, but they aren't as good as Duplicate Cleaner, and also don't have the functionality I need.) Thanks for any help.

• Sonicwall settings for Polycom TFTP

  - by Michael Glenn

  I'm switching our VoIP phones (Polycom 301s and 501s) to our data network. They were previously segmented to their own network. This means disabling the DHCP on the Trixbox (Asterisk) server and configuring the Sonicwall TZ 210 DHCP to indicate that Trixbox is the TFTP server. The Polycom phones are stating "could not contact boot server". All phones are configured to TFTP and were confirmed working when previously using the Trixbox server for DHCP. Trixbox DHCP is now turned off. I've configured options 66(as String), 128(as IP) and 150(as IP) in DHCP and added them to a TFTP Option Group. I've enabled "Allow BOOTP Clients to use Range" for the Dynamic IP range and assigned the Option Group TFTP as the DHCP Generic Option Group. Any idea what I'm missing? Is there a separate tool to inspect the DHCP response to compare Trixbox to the Sonicwall?

• How to detect a change in a background window

  - by Leonardo

  Hi, Let's say I have a chat window open in a web browser, and I'm waiting for a message from my partner, trying to do something else in the meantime. The chat window (not an installed program) will not alert me of an incoming message, nor will the task bar flash or anything. Is there any utility that can help me? In search of a solution, I came across AutoHotKey. There is a script called livewindows.ahk, which will show a piece of the window anywhere on the screen, but it won't alert me on a change. I'm not skilled enough to know how to store and compare e.g. every second's content of some window area. Maybe someone has invented this wheel? Thanks in advance for any hint or advice. Leonardo
