• Server load increases by lot of httpd request with same PID

  - by user3740955

  I can see that my server load increases to more than 200-300 range. Before 1 week the maximum load was around 20-25. In top and ps -ef i can see a lot of httpd threads and the PPID of most of the httpd request are of the same PID. When i verified this the parent process ID is of root. Please let me know how i can reduce the server load. I have searched a lot for this but not able to find out a proper solution for this. Please let me know. Please see below a part of the top output. apache 29698 2062 1 16:54 ? 00:00:00 /usr/sbin/httpd apache 29700 2062 3 16:54 ? 00:00:00 /usr/sbin/httpd apache 29701 2062 10 16:54 ? 00:00:02 /usr/sbin/httpd apache 29702 2062 0 16:54 ? 00:00:00 /usr/sbin/httpd apache 29703 2062 1 16:54 ? 00:00:00 /usr/sbin/httpd apache 29705 2062 0 16:54 ? 00:00:00 /usr/sbin/httpd apache 29706 2062 3 16:54 ? 00:00:00 /usr/sbin/httpd apache 29707 2062 0 16:54 ? 00:00:00 /usr/sbin/httpd apache 29708 2062 1 16:54 ? 00:00:00 /usr/sbin/httpd apache 29709 2062 0 16:54 ? 00:00:00 /usr/sbin/httpd apache 29710 2062 0 16:54 ? 00:00:00 /usr/sbin/httpd apache 29711 2062 0 16:54 ? 00:00:00 /usr/sbin/httpd apache 29712 2062 0 16:54 ? 00:00:00 /usr/sbin/httpd Server version: Apache/2.2.3

• Combine multiple network interfaces to connect to a dedicated server

  - by Dženis Macanovic

  this is an underpaid employee writing, who's apparently responsible for all the IT stuff in a very small (non-IT) company. Today said company got a bunch of PCs/workstations, a switch, a computer that's supposed to be used as a router, two DSL connections (each 16 MBit/s downstream and 1 MBit/s upstream) and a dedicated server which is hosted and managed professionally by a larger local company with some decent connection speed (1 GBit/s both directions if I'm not mistaken). This is what I've set up (note I'm not making use of the second DSL connection at all)... ETH0 ETH1 [ SWITCH ]---[LINUX DEBIAN ROUTER]---[DSL MODEM 1]---[INTERNET] | | | PC1 | | PC2 | ... ... when my boss asked me, if it was somehow possible to get 32 MBit/s downstream and 2 MBit/s upstream. At that time I replied "no" without thinking too much about it. Now I've just had the following idea... ETH1 ETH0 ETH0 ,---[DSL MODEM 1 (NON-STATIC IP)]---, ,---, ETH0 [ SWITCH ]---[LINUX DEBIAN ROUTER] [INTERNET] [LINUX DEBIAN SERVER]---[INTERNET] | | | '---[ DSL MODEM 2 (STATIC IP) ]---' '---' PC1 | | ETH2 ETH0 PC2 | ... ... but I have absolutely no clue how to implement that. Would that even be possible? What would the masquerading rules look like on the router? What about the server? I didn't find anything on the internet, mainly because I couldn't come up with any good keywords to search for to begin with. English obviously isn't my first language. Thanks in advance for your time!

• Windows Server 2008 Alerting to Low memory

  - by t1nt1n

  I have a file and print server running on Windows 2008 R2 fully patched in a VSphere environment (ESXi 5.1 fully updated). Every evening between 19:20 and 19:30 our monitoring software reported that the available memory is 1% and performance is dire. There is nothing in the event logs to point to an issue. At this point in the evening I am general the only user on the system to check to see why these alerts are going off. Things I have done; Checked to see if any backups are running – None at all. Checked Scheduled tasks – None before or during this time period. Moved the VM to another host. AV is disabled to rule out that as the issue. The server does not have any problems during the day with memory when fully loaded with about 50 users. The server did have 4GB ram provisioned but I have increased this to 5Gb. Running PrefMon at the time (I will save the graphs tonight) There very little CPU usage at the time but RAM usage goes up.

• 5 year old server upgrade

  - by rizzo0917

  I am looking to upgrade a server for a web app. Currently the application is running very sluggish. We've made some adjustments to mysql (that's another issue in itself) and made some adjustments so that heaviest quires get run on a copy of the database on another server was have as a backup, however this will not last that much longer and we are looking to upgrade. Currently the servers CPUs are (4) Intel(R) XEON(TM) CPU 2.00GHz, with 1 gig of ram. The database is 442.5 MiB, with about 1,743,808 records. There are two parts of the program, the one, side a, inserts and updates most of the data. Side b, reads the data and does some minor updates. Currently our biggest day for side a are 800 users (of 40,000 users all year) imputing the system. And our Side b is currently unknown, however we have a total of 1000 clients. The system is most likely going to cap out at 5000 side b clients, with about a year 300,000 side a users. The current database is 5 years old, so we can most likely expect the database to grow pretty rapidly, possibly double each year (which we can most likely archive older records if it comes to that). So with that being said, should we get a server for each side of the app, side a being the master, side b being the slave, any updates made on side b are router to side a. So the question is should i get 2 of these or 1. 2 x Intel Nehalem Xeon E5520 2.26Ghz (8 Cores) 12GB DDRIII Memory 500GB SATAII HDD 100Mbps Port Speed And Naturally I would need to have a redundant backup so it could potentially be 4 of them.

• Advantage Database Server: slow stored procedure performance.

  - by ie

  I have a question about a performance of stored procedures in the ADS. I created a simple database with the following structure: CREATE TABLE MainTable ( Id INTEGER PRIMARY KEY, Name VARCHAR(50), Value INTEGER ); CREATE UNIQUE INDEX MainTableName_UIX ON MainTable ( Name ); CREATE TABLE SubTable ( Id INTEGER PRIMARY KEY, MainId INTEGER, Name VARCHAR(50), Value INTEGER ); CREATE INDEX SubTableMainId_UIX ON SubTable ( MainId ); CREATE UNIQUE INDEX SubTableName_UIX ON SubTable ( Name ); CREATE PROCEDURE CreateItems ( MainName VARCHAR ( 20 ), SubName VARCHAR ( 20 ), MainValue INTEGER, SubValue INTEGER, MainId INTEGER OUTPUT, SubId INTEGER OUTPUT ) BEGIN DECLARE @MainName VARCHAR ( 20 ); DECLARE @SubName VARCHAR ( 20 ); DECLARE @MainValue INTEGER; DECLARE @SubValue INTEGER; DECLARE @MainId INTEGER; DECLARE @SubId INTEGER; @MainName = (SELECT MainName FROM __input); @SubName = (SELECT SubName FROM __input); @MainValue = (SELECT MainValue FROM __input); @SubValue = (SELECT SubValue FROM __input); @MainId = (SELECT MAX(Id)+1 FROM MainTable); @SubId = (SELECT MAX(Id)+1 FROM SubTable ); INSERT INTO MainTable (Id, Name, Value) VALUES (@MainId, @MainName, @MainValue); INSERT INTO SubTable (Id, Name, MainId, Value) VALUES (@SubId, @SubName, @MainId, @SubValue); INSERT INTO __output SELECT @MainId, @SubId FROM system.iota; END; CREATE PROCEDURE UpdateItems ( MainName VARCHAR ( 20 ), MainValue INTEGER, SubValue INTEGER ) BEGIN DECLARE @MainName VARCHAR ( 20 ); DECLARE @MainValue INTEGER; DECLARE @SubValue INTEGER; DECLARE @MainId INTEGER; @MainName = (SELECT MainName FROM __input); @MainValue = (SELECT MainValue FROM __input); @SubValue = (SELECT SubValue FROM __input); @MainId = (SELECT TOP 1 Id FROM MainTable WHERE Name = @MainName); UPDATE MainTable SET Value = @MainValue WHERE Id = @MainId; UPDATE SubTable SET Value = @SubValue WHERE MainId = @MainId; END; CREATE PROCEDURE SelectItems ( MainName VARCHAR ( 20 ), CalculatedValue INTEGER OUTPUT ) BEGIN DECLARE @MainName VARCHAR ( 20 ); @MainName = (SELECT MainName FROM __input); INSERT INTO __output SELECT m.Value * s.Value FROM MainTable m INNER JOIN SubTable s ON m.Id = s.MainId WHERE m.Name = @MainName; END; CREATE PROCEDURE DeleteItems ( MainName VARCHAR ( 20 ) ) BEGIN DECLARE @MainName VARCHAR ( 20 ); DECLARE @MainId INTEGER; @MainName = (SELECT MainName FROM __input); @MainId = (SELECT TOP 1 Id FROM MainTable WHERE Name = @MainName); DELETE FROM SubTable WHERE MainId = @MainId; DELETE FROM MainTable WHERE Id = @MainId; END; Actually, the problem I had - even so light stored procedures work very-very slow (about 50-150 ms) relatively to plain queries (0-5ms). To test the performance, I created a simple test (in F# using ADS ADO.NET provider): open System; open System.Data; open System.Diagnostics; open Advantage.Data.Provider; let mainName = "main name #"; let subName = "sub name #"; // INSERT let cmdTextScriptInsert = " DECLARE @MainId INTEGER; DECLARE @SubId INTEGER; @MainId = (SELECT MAX(Id)+1 FROM MainTable); @SubId = (SELECT MAX(Id)+1 FROM SubTable ); INSERT INTO MainTable (Id, Name, Value) VALUES (@MainId, :MainName, :MainValue); INSERT INTO SubTable (Id, Name, MainId, Value) VALUES (@SubId, :SubName, @MainId, :SubValue); SELECT @MainId, @SubId FROM system.iota;"; let cmdTextProcedureInsert = "CreateItems"; // UPDATE let cmdTextScriptUpdate = " DECLARE @MainId INTEGER; @MainId = (SELECT TOP 1 Id FROM MainTable WHERE Name = :MainName); UPDATE MainTable SET Value = :MainValue WHERE Id = @MainId; UPDATE SubTable SET Value = :SubValue WHERE MainId = @MainId;"; let cmdTextProcedureUpdate = "UpdateItems"; // SELECT let cmdTextScriptSelect = " SELECT m.Value * s.Value FROM MainTable m INNER JOIN SubTable s ON m.Id = s.MainId WHERE m.Name = :MainName;"; let cmdTextProcedureSelect = "SelectItems"; // DELETE let cmdTextScriptDelete = " DECLARE @MainId INTEGER; @MainId = (SELECT TOP 1 Id FROM MainTable WHERE Name = :MainName); DELETE FROM SubTable WHERE MainId = @MainId; DELETE FROM MainTable WHERE Id = @MainId;"; let cmdTextProcedureDelete = "DeleteItems"; let cnnStr = @"data source=D:\DB\test.add; ServerType=local; user id=adssys; password=***;"; let cnn = new AdsConnection(cnnStr); try cnn.Open(); let cmd = cnn.CreateCommand(); let parametrize ix prms = cmd.Parameters.Clear(); let addParam = function | "MainName" -> cmd.Parameters.Add(":MainName" , mainName + ix.ToString()) |> ignore; | "SubName" -> cmd.Parameters.Add(":SubName" , subName + ix.ToString() ) |> ignore; | "MainValue" -> cmd.Parameters.Add(":MainValue", ix * 3 ) |> ignore; | "SubValue" -> cmd.Parameters.Add(":SubValue" , ix * 7 ) |> ignore; | _ -> () prms |> List.iter addParam; let runTest testData = let (cmdType, cmdName, cmdText, cmdParams) = testData; let toPrefix cmdType cmdName = let prefix = match cmdType with | CommandType.StoredProcedure -> "Procedure-" | CommandType.Text -> "Script -" | _ -> "Unknown -" in prefix + cmdName; let stopWatch = new Stopwatch(); let runStep ix prms = parametrize ix prms; stopWatch.Start(); cmd.ExecuteNonQuery() |> ignore; stopWatch.Stop(); cmd.CommandText <- cmdText; cmd.CommandType <- cmdType; let startId = 1500; let count = 10; for id in startId .. startId+count do runStep id cmdParams; let elapsed = stopWatch.Elapsed; Console.WriteLine("Test '{0}' - total: {1}; per call: {2}ms", toPrefix cmdType cmdName, elapsed, Convert.ToInt32(elapsed.TotalMilliseconds)/count); let lst = [ (CommandType.Text, "Insert", cmdTextScriptInsert, ["MainName"; "SubName"; "MainValue"; "SubValue"]); (CommandType.Text, "Update", cmdTextScriptUpdate, ["MainName"; "MainValue"; "SubValue"]); (CommandType.Text, "Select", cmdTextScriptSelect, ["MainName"]); (CommandType.Text, "Delete", cmdTextScriptDelete, ["MainName"]) (CommandType.StoredProcedure, "Insert", cmdTextProcedureInsert, ["MainName"; "SubName"; "MainValue"; "SubValue"]); (CommandType.StoredProcedure, "Update", cmdTextProcedureUpdate, ["MainName"; "MainValue"; "SubValue"]); (CommandType.StoredProcedure, "Select", cmdTextProcedureSelect, ["MainName"]); (CommandType.StoredProcedure, "Delete", cmdTextProcedureDelete, ["MainName"])]; lst |> List.iter runTest; finally cnn.Close(); And I'm getting the following results: Test 'Script -Insert' - total: 00:00:00.0292841; per call: 2ms Test 'Script -Update' - total: 00:00:00.0056296; per call: 0ms Test 'Script -Select' - total: 00:00:00.0051738; per call: 0ms Test 'Script -Delete' - total: 00:00:00.0059258; per call: 0ms Test 'Procedure-Insert' - total: 00:00:01.2567146; per call: 125ms Test 'Procedure-Update' - total: 00:00:00.7442440; per call: 74ms Test 'Procedure-Select' - total: 00:00:00.5120446; per call: 51ms Test 'Procedure-Delete' - total: 00:00:01.0619165; per call: 106ms The situation with the remote server is much better, but still a great gap between plaqin queries and stored procedures: Test 'Script -Insert' - total: 00:00:00.0709299; per call: 7ms Test 'Script -Update' - total: 00:00:00.0161777; per call: 1ms Test 'Script -Select' - total: 00:00:00.0258113; per call: 2ms Test 'Script -Delete' - total: 00:00:00.0166242; per call: 1ms Test 'Procedure-Insert' - total: 00:00:00.5116138; per call: 51ms Test 'Procedure-Update' - total: 00:00:00.3802251; per call: 38ms Test 'Procedure-Select' - total: 00:00:00.1241245; per call: 12ms Test 'Procedure-Delete' - total: 00:00:00.4336334; per call: 43ms Is it any chance to improve the SP performance?

• Unable to connect SQL Server instance from Visual Studio 2008 Version 9.0

  - by salvationishere

  I am getting the below error from VS on an 32-bit XP Professional server even though I set Tools-Options-Database Tools-Data Connections to "SIDEKICK", which is the name of my computer. In other words SIDEKICK should default to the full SQLSERVER. In other words, I want VS to use SQLSERVER instead of SQLSERVER EXPRESS. And I can clearly see my database both from VS in the Server Explorer and also in SSMS 2008. Furthermore, I can view the tables of this database in Server Explorer from VS. I do not get any build errors. And it looks like all of the naming is consistent in my web.config file. I am developing my website according to a Microsoft tutorial, so I should not be getting an error. Yet I get the following exception when I run this code below: CreateAccounts.aspx.cs file protected void CreateAccountButton_Click(object sender, EventArgs e) { MembershipCreateStatus createStatus; //This line below is where the exception occurs MembershipUser newUser = Membership.CreateUser(Username.Text, Password.Text, Email.Text, passwordQuestion, SecurityAnswer.Text, true, out createStatus); And here is what the exception looks like: System.Web.HttpException was unhandled by user code Message="Unable to connect to SQL Server database."

• Setting Up TFS Server outside of a domain

  - by Ben

  Hi Im trying to set up TFS 2010 on a machine that is connected to a network, but not on the domain. I am trying to connect this to a SQL Server that is also connected to the network and also not on the domain. When I run through the TFS configuration Wizard and try to connect to the SQL Server, it fails with a message "A connection can not be made...." which looks like it cant see the Server. However when i connect through SQL Management Studio it works when i use SQL Authentication (not Windows Auth). I beleive its failing because TFS needs to connect using Windows Authetication (please correct me if im wrong). I can not add the Windows Authentication for my TFS machine onto the SQL machine becuase they are on different domains (again, pleas correct me if I'm wrong). Does anyone have any suggestions? Thanks.

• How can i test my DB speed? (Learning)

  - by acidzombie24

  I have design a database. Theres no columns with indexing, nor any code for optimizing. I am positive i should index certain columns since i search them a lot. My question is HOW do i test if any part of my database will be slow? ATM I am using sqlite and i will be switching to either MS Sql or MySql based on my host provider. Will creating 100,000 records in each table be enough? Or will that always be fast in sqlite and i need to do 1mil? Do i need 10mil before a database will become slow? Also how do i time it? I am using C# so should i use StopWatch or is there a ADO.NET/Sqlite function i should use?

• Caching result of SELECT statement for reuse in multiple queries

  - by Andrew

  I have a reasonably complex query to extract the Id field of the results I am interested in based on parameters entered by the user. After extracting the relevant Ids I am using the resulting set of Ids several times, in separate queries, to extract the actual output record sets I want (by joining to other tables, using aggregate functions, etc). I would like to avoid running the initial query separately for every set of results I want to return. I imagine my situation is a common pattern so I am interested in what the best approach is. The database is in MS SQL Server and I am using .NET 3.5.

• Are conditional subqueries optimized out, if the condition is false?

  - by Tobias Schulte

  I have a table foo and a table bar, where each foo might have a bar (and a bar might belong to multiple foos). Now I need to select all foos with a bar. My sql looks like this SELECT * FROM foo f WHERE [...] AND ($param IS NULL OR (SELECT ((COUNT(*))>0) FROM bar b WHERE f.bar = b.id)) with $param being replaced at runtime. The question is: Will the subquery be executed even if param is null, or will the dbms optimize the subquery out? We are using mysql, mssql and oracle. Is there a difference between these regarding the above?

• WS2008 subst in Logon script does not "stick"

  - by Frans

  I have a terminal server environment exclusively with Windows Server 2008. My problem is that I need to "map" a drive letter to each users Temp folder. This is due to a legacy app that requries a separate Temp folder for each user but which does not understand %temp%. So, just add "subst t: %temp%" to the logon script, right? The problem is that, even though the command runs, the subst doesn't "stick" and the user doesn't get a T: drive. Here is what I have tried; The simplest version: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") WinShell.Run "subst T: %temp%", 2, True That didn't work, so tried this for more debug information: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") Set procEnv = WinShell.Environment("Process") wscript.echo(procEnv("TEMP")) tempDir = procEnv("TEMP") WinShell.Run "subst T: " & tempDir, 3, True This shows me the correct temp path when the user logs in - but still no T: Drive. Decided to resort to brute force and put this in my login script: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") WinShell.Run "\\domain\sysvol\esl.hosted\scripts\tempdir.cmd", 3, True where \domain\sysvol\esl.hosted\scripts\tempdir.cmd has this content: echo on subst t: %temp% pause When I log in with the above then the command window opens up and I can see the subst command being executed correctly, with the correct path. But still no T: drive. I have tried running all of the above scripts outside of a login script and they always work perfectly - this problem only occurs when doing it from inside a login script. I found a passing reference on an MSFN forum about a similar problem when the user is already logged on to another machine - but I have this problem even without being logged on to another machine. Any suggestion on how to overcome this will be much appreciated.

• Exchange 2007 two node cluster setup on Windows 2008 Enterprise, install error

  - by Shadow00Caster

  I am installing Microsoft Exchange 2007 x64 in a two node environment using Microsoft Windows 2008 Enterprise x64. The Failover Cluster is all setup properly and following best practices for setting up the windows clustering for use with Exchange 2007. All the validation tests pass on the cluster and all of that portion is working fine. The problem is when I go to install the first Exchange node as an Active mailbox in configuration for a two node CCR. It gets all the way through the first 3 steps (Copy Exchange Files, Management Tools, Mailbox Role) and then fails on the 4th step 'Clustered Mailbox Server' with the following error: Error: The clustered mailbox server's group 'XXXX' was not found, and should already exist. Firewalls are all disabled, DNS is all setup properly, the environment has 3 domain controllers all 2k8 ent x64, all replication works. The name I pick for the CCR cluster (XXX) does not exist in AD or in DNS. I have attempted this install from both of the two Exchange nodes and multiple times .. tried with different names. I have been banging my head against the wall for days working on this and would appreciate any feedback on the issue.

• Windows 2008 RemoteAPP client disconnects within a matter of minutes

  - by Jeroen Wilke

  I'm having an odd problem with Windows 2008 TS, and remote applications specifically. The situation is as follows: TS idle timeout is disabled via GPO TS terminating disconnected sessions after 1hr (via GPO) My users can log on to the Terminal server, and get a full desktop, OR via rdp files that give access to a few remote applications. When a user connects to a full desktop, everything is fine and dandy, they will remain logged on indefinately, and when they disconnect the session is terminated after an hour. however, when a user connects using a remote application link, the client seems to disconnect after only a few minutes of inactivity, when you click the window, the session reconnects. EventID's on TS server: 4779: This event is generated when a user disconnects from an existing Terminal Services session, or when a user switches away from an existing destop using Fast User Switching. 4778 : This event is generated when a user reconnects to an existing Terminal Services session, or when a user switches to an existing desktop using Fast User Switching users are connecting directly to 3389, not using a TS-gateway at the moment. This behavior is consistent on different clients that we have, Full desktop is fine, RemoteAPP constantly disconnects. The .rdp file used doesn't list any interesting parameters, aside from what application to launch, and where to find it. Can someone explain to me how there can be a difference in behaviour between full desktop, and remoteapp ? since essentially they use the exact same client ? Regards Jeroen

• SPARC M7 Chip - 32 cores - Mind Blowing performance

  - by Angelo-Oracle

  The M7 Chip Oracle just announced its Next Generation Processor at the HotChips HC26 conference. As the Tech Lead in our Systems Division's Partner group, I had a front row seat to the extraordinary price performance advantage of Oracle current T5 and M6 based systems. Partner after partner tested  these systems and were impressed with it performance. Just read some of the quotes to see what our partner has been saying about our hardware. We just announced our next generation processor, the M7. This has 32 cores (up from 16-cores in T5 and 12-cores in M6). With 20 nm technology  this is our most advanced processor. The processor has more cores than anything else in the industry today. After the Sun acquisition Oracle has released 5 processors in 4 years and this is the 6th.  The S4 core  The M7 is built using the foundation of the S4 core. This is the next generation core technology. Like its predecessor, the S4 has 8 dynamic threads. It increases the frequency while maintaining the Pipeline depth. Each core has its own fine grain power estimator that keeps the core within its power envelop in 250 nano-sec granularity. Each core also includes Software in Silicon features for Application Acceleration Support. Each core includes features to improve Application Data Integrity, with almost no performance loss. The core also allows using part of the Virtual Address to store meta-data.  User-Level Synchronization Instructions are also part of the S4 core. Each core has 16 KB Instruction and 16 KB Data L1 cache. The Core Clusters  The cores on the M7 chip are organized in sets of 4-core clusters. The core clusters share  L2 cache.  All four cores in the complex share 256 KB of 4 way set associative L2 Instruction Cache, with over 1/2 TB/s of throughput. Two cores share 256 KB of 8 way set associative L2 Data Cache, with over 1/2 TB/s of throughput. With this innovative Core Cluster architecture, the M7 doubles core execution bandwidth. to maximize per-thread performance.  The Chip  Each  M7 chip has 8 sets of these core-clusters. The chip has 64 MB on-chip L3 cache. This L3 caches is shared among all the cores and is partitioned into 8 x 8 MB chunks. Each chunk is  8-way set associative cache. The aggregate bandwidth for the L3 cache on the chip is over 1.6TB/s. Each chip has 4 DDR4 memory controllers and can support upto 16 DDR4 DIMMs, allowing for 2 TB of RAM/chip. The chip also includes 4 internal links of PCIe Gen3 I/O controllers.  Each chip has 7 coherence links, allowing for 8 of these chips to be connected together gluelessly. Also 32 of these chips can be connected in an SMP configuration. A potential system with 32 chips will have 1024 cores and 8192 threads and 64 TB of RAM.  Software in Silicon The M7 chip has many built in Application Accelerators in Silicon. These features will be exposed to our Software partners using the SPARC Accelerator Program.  The M7  has built-in logic to decompress data at the speed of memory access. This means that applications can directly work on compressed data in memory increasing the data access rates. The VA Masking feature allows the use of part of the virtual address to store meta-data.  Realtime Application Data Integrity The Realtime Application Data Integrity feature helps applications safeguard against invalid, stale memory reference and buffer overflows. The first 4-bits if the Pointer can be used to store a version number and this version number is also maintained in the memory & cache lines. When a pointer accesses memory the hardware checks to make sure the two versions match. A SEGV signal is raised when there is a mismatch. This feature can be used by the Database, applications and the OS.  M7 Database In-Memory Query Accelerator The M7 chip also includes a In-Silicon Query Engines.  These accelerate tasks that work on In-Memory Columnar Vectors. Oracle In-Memory options stores data in Column Format. The M7 Query Engine can speed up In-Memory Format Conversion, Value and Range Comparisons and Set Membership lookups. This engine can work on Compressed data - this means not only are we accelerating the query performance but also increasing the memory bandwidth for queries.  SPARC Accelerated Program  At the Hotchips conference we also introduced the SPARC Accelerated Program to provide our partners and third part developers access to all the goodness of the M7's SPARC Application Acceleration features. Please get in touch with us if you are interested in knowing more about this program.

• Multiple IPv6 addresses being assigned to single interface

  - by Steven Copestake

  I'm configuring a DHCP scope for IPv6, however all my clients are getting 2 or more IPv6 addresses assigned to the interface. I'm using fda8:6c3:ce53:a890:/64 as the prefix. The scope is on a machine running Windows Server 2008 R2 however I'm looking to roll it out on Server 2012 as well. My clients are getting the following: IPv6 Address. . . . . . . . . . . : 1024::1492:9288:7357:7d30(Preferred) IPv6 Address. . . . . . . . . . . : fda8:6c3:ce53:a890::1(Preferred) IPv6 Address. . . . . . . . . . . : fda8:6c3:ce53:a890:1492:9288:7357:7d30(Pr rred) Link-local IPv6 Address . . . . . : fe80::1492:9288:7357:7d30%10(Preferred) In this example there's no DHCP scope and the machine has a static IP of fda8:6c3:ce53:a890::1. With this in mind where are the 1024 address and the fda8:6c3:ce53:a890:1492:9288:7357:7d30 address coming from?

• PDFs and Networked Printers

  - by Bart Silverstrim

  Weird issue. We have users printing to networked windows-shared printers (print server Win2003 sp2). Some users have been reporting recently that they can't print PDF documents to particular printers (two example printers are HP 2430 PCL 6 driver and 4250 PCL 6 driver). At first, we found that on many of these systems the "Everyone" object was added to the permissions for the root of the C: volume but had no permissions checked. We added modify privileges to it (these are Deep-Freeze systems, so modifications to these systems that we don't add as administrators won't matter) and they seemed to be able to print. Perhaps Acrobat Reader was writing a temp file for printing where users didn't have permission, we surmised, and made the change and moved on. Yesterday the user called in saying it's not working still. Looked at it; bring up a PDF, click Print and the reader app says that you have to install a printer. Look at the printers folder (Windows XP workstation), and it has printers installed. Print a test page, return to AcroReader, and it will print fine to that printer. The whole time web pages, MS Office documents, etc. print without issue to the same printers. Has anyone seen this issue with Acro Reader 9 and certain network printer drivers or shares involving HP printers? I'd post this to SuperUser but it seems to be associated with a networked printer issue, seems to affect subsets of users but may be more widespread and our users aren't reporting it to us assuming we just know about it, and I've not found rhyme or reason as to why it's affecting just PDF printing and particular printers. The print spoolers are all running on the workstations and print server without errors being logged so far, but I'm going through the logs now to see if I can find anything out of place.

• restoring a failed SBS 2000 box...

  - by Brad Pears

  Hi there, I read a post where you had mentioned you have had a PERC card blow up on you in an SBS box... I've got a similar situation where one of my RAID drives failed and then the power supply failed before I could replace the drive... I then replaced the power supply and the failed drive and reconfigured the RAID array. I had a recent full backup of the my Win2k SBS's C: drive stored on my SYmantec backup exec server so I installed win2K server on the c: partition and then once I had that up and running, installed the backup exec agent so as to do a restore of the entire c drive including system state. THis all worked just fine, until I had to reboot. I received an "incorrect drive configuration" error and then it hangs. I figure that likely makes sense becasue I think my RAID array is configured slightly different now in that the partitions may be sizeded ever so slightly differently now than they were before I think... Is there a way I can just restore from my backup BUT maybe exclude some of the registry and hidden boot files it wants to restore so that it is booting with the current configuration now active on that machine - not the pre blow up configuration files? I also read a post that indicated you might have to install the exact same service pack etc... etc.. before attemting a restore but that does not make sense to me being as the entire c drive contents are going to be overwritten by the restore anyway? THe basic OS install is just to be able to get the backup exec agent installed . I can;t understand why one would need to install the exact same SP level. CAn you shed some light on what I might be able to do to get this thing up and running? Thanks,Brad

• Slow File Copy observed copying 40GB files across network to iSCSI device

  - by Rick

  Here's a curious ones for the gurus: Setup: Source Machine: Windows Server 2003 R2 machine with local hard drive. VHD file of 40GB. 1 x 1Gbps network card, Cat6 cable, switch. Target Machine: Windows Server 2008 R2 machine with iSCSI connection to iSCSI target on separate machine (1TB, RAID5). 1 x 1Gbps network card, Cat6 cable, connected to same switch as for Source Machine. Second 1Gbps network card, Cat6 cable, connected via isolated switch to the iSCSI target. Switches are Netgear JGS524 model (web managed). If I copy from the Win2003R2 machine to Win2008R2 machine local drive I get 40GB in 45 minutes, 36 seconds. If I copy from the Win2008R2 machine to the iSCSI target (local drive to iSCSI target) I get 40GB in 37 minutes 56 seconds. If I copy from the Win2003R2 machine to the iSCSI target via the Win2008R2 machine I get 40GB in 3 hours, 50 minutes, 24 seconds. All copies were done via the following command issued on the Win2008R2 box: XCOPY <source> <target> /J XCOPY /J - Copies using unbuffered I/O. Recommended for very large files. So, what's the bit I'm missing here? Why does a back-to-back copy take in total 1 hour, 23 minutes, 32 seconds when a "straight through" copy take almost 3 times as long? Switches show no errors, network hovers around the 3% utilisation mark for the duration of the copy (whereas the "back-to-back" copies are around the 25% utilisation mark). What have I missed?

• SPARC T4-4 Delivers World Record Performance on Oracle OLAP Perf Version 2 Benchmark

  - by Brian

  Oracle's SPARC T4-4 server delivered world record performance with subsecond response time on the Oracle OLAP Perf Version 2 benchmark using Oracle Database 11g Release 2 running on Oracle Solaris 11. The SPARC T4-4 server achieved throughput of 430,000 cube-queries/hour with an average response time of 0.85 seconds and the median response time of 0.43 seconds. This was achieved by using only 60% of the available CPU resources leaving plenty of headroom for future growth. The SPARC T4-4 server operated on an Oracle OLAP cube with a 4 billion row fact table of sales data containing 4 dimensions. This represents as many as 90 quintillion aggregate rows (90 followed by 18 zeros). Performance Landscape Oracle OLAP Perf Version 2 Benchmark 4 Billion Fact Table Rows System Queries/hour Users* Response Time (sec) Average Median SPARC T4-4 430,000 7,300 0.85 0.43 * Users - the supported number of users with a given think time of 60 seconds Configuration Summary and Results Hardware Configuration: SPARC T4-4 server with 4 x SPARC T4 processors, 3.0 GHz 1 TB memory Data Storage 1 x Sun Fire X4275 (using COMSTAR) 2 x Sun Storage F5100 Flash Array (each with 80 FMODs) Redo Storage 1 x Sun Fire X4275 (using COMSTAR with 8 HDD) Software Configuration: Oracle Solaris 11 11/11 Oracle Database 11g Release 2 (11.2.0.3) with Oracle OLAP option Benchmark Description The Oracle OLAP Perf Version 2 benchmark is a workload designed to demonstrate and stress the Oracle OLAP product's core features of fast query, fast update, and rich calculations on a multi-dimensional model to support enhanced Data Warehousing. The bulk of the benchmark entails running a number of concurrent users, each issuing typical multidimensional queries against an Oracle OLAP cube consisting of a number of years of sales data with fully pre-computed aggregations. The cube has four dimensions: time, product, customer, and channel. Each query user issues approximately 150 different queries. One query chain may ask for total sales in a particular region (e.g South America) for a particular time period (e.g. Q4 of 2010) followed by additional queries which drill down into sales for individual countries (e.g. Chile, Peru, etc.) with further queries drilling down into individual stores, etc. Another query chain may ask for yearly comparisons of total sales for some product category (e.g. major household appliances) and then issue further queries drilling down into particular products (e.g. refrigerators, stoves. etc.), particular regions, particular customers, etc. Results from version 2 of the benchmark are not comparable with version 1. The primary difference is the type of queries along with the query mix. Key Points and Best Practices Since typical BI users are often likely to issue similar queries, with different constants in the where clauses, setting the init.ora prameter "cursor_sharing" to "force" will provide for additional query throughput and a larger number of potential users. Except for this setting, together with making full use of available memory, out of the box performance for the OLAP Perf workload should provide results similar to what is reported here. For a given number of query users with zero think time, the main measured metrics are the average query response time, the median query response time, and the query throughput. A derived metric is the maximum number of users the system can support achieving the measured response time assuming some non-zero think time. The calculation of the maximum number of users follows from the well-known response-time law N = (rt + tt) * tp where rt is the average response time, tt is the think time and tp is the measured throughput. Setting tt to 60 seconds, rt to 0.85 seconds and tp to 119.44 queries/sec (430,000 queries/hour), the above formula shows that the T4-4 server will support 7,300 concurrent users with a think time of 60 seconds and an average response time of 0.85 seconds.

• Windows Server 2008 R2 - Cannot Change DNS Domain Context on Some Machines

  - by Richie086

  So I have a small Windows Server 2008 R2 network consisting of a domain controller, a file server, sql server, etc. All machines are joined to a windows domain (CPUSHIELD.COM) and show up in Active Directory Users and Computers under the Computers OU. Each computer has a DNS record as well that was populated when I joined each computer to the domain. However, when I go to my SQL server VM (which is joined to CPUSHIELD.COM) and try to add domain users or groups to the local users or groups on my file server (which is a physical machine) or my sql server (which is a virtual machine), for some reason I cannot change the context to the CPUSHIELD.COM domain.. For example: Here is the really strange thing, I have two other servers on my network that do show CPUSHIELD.COM in the From This Location field (as I would expect with any machine joined to a domain) and I am able to search the local machine and/or domain for users/groups to add. I have done hundreds of Windows Server 2008 installs and this is the first time I have run into this issue. Any ideas? Let me know if you need more info

• Hyper-v on 2012R2 startup gen1 vm causes the host to freeze up

  - by sputnik

  I've searched a lot to resolve the following issue, but nothing helped me. My problem is, that starting up a first-gen vm locks up the whole host. Only a hard reset helps. Second-gen vm starts and runs perfectly. The freezes happened on 3 different vms. FreeBSD, Ubuntu, Windows Server 2008R2, while Windows 8.1 on second gen config works perfectly. Im using this pc mainly as a workstation. No eventlog errors nor dumps are generated. My system: Windows Server 2012R2 FX-8350, non OC ASRock 870 Extreme R2 (Crappy board imho) 32GB DDR3 1866@1600 (My motherboard, against the "support" for 1866ram won't work with full speed) 120GB SSD 4.5TB Storage space device I dont think that its due to my system, because vmware workstation was running without problems. Did I forget to configure something? Any help is appreciated. P.S: Even deactivating C1E, C6, C&Q didnt work. P.P.S: With no virtual network adapter set, the system still locks up. Creating a first gen vm without any hdds and network and launching works. Attaching a boot dvd causes the host to freeze. The host freezes as the gen1 vm begins to boot, doesn't matter if from dvd or hdd
