  • mount.nfs: access denied by server while mounting (null), can't find any log information

    - by Mark0978
    Two ubuntu servers: 10.0.8.2 is the client, 192.168.20.58 is the server. Between the 2 machines, Ping works, ssh works (in both directions).

  • Why are people trying to connect to me network on TCP port 445?

    - by Solignis
    I was playing with my new syslog server and had my m0n0wall firewall logs forwarded as a test, I noticed a bunch of recent firewall log entries that say that it blocked other WAN IPs from my ISP (I checked) from connecting to me on TCP port 445. Why would a random computer be trying to connect to me on a port apperently used for Windows SMB shares? Just internet garbage? A port scan?

  • Can't get DHCPd to assign IPs to unknown clients

    - by Jakobud
    I'm using Webmin to admin our DHCPd server. But I'm having a hard time getting it to assign IP addresses to unknown clients. The only way I can get it to assign an IP is to make sure a host is added to DHCPd as a host so that it gets a static-lease IP assigned to it. I thought "Allow Unknown Clients" was the key, but it still isn't assigning IPs to unknown clients. I have a pool setup so that the unknown clients should get an IP between 10.20.0.200 - 10.20.0.249. Here is the config file. What am I missing here? allow unknown-clients; # Primary DHCP server config authoritative; ddns-update-style none; failover peer "dhcp-failover" { primary; address 10.20.0.30; port 647; peer address 10.20.0.25; peer port 647; max-response-delay 60; max-unacked-updates 10; load balance max seconds 3; mclt 3600; split 128; } subnet 10.20.0.0 netmask 255.255.255.0 { allow unknown-clients; option subnet-mask 255.255.255.0; option broadcast-address 10.20.0.255; option routers 10.20.0.100; option domain-name "ourdomain.com"; option domain-name-servers 192.168.10.20; default-lease-time 86400; max-lease-time 86400; option ntp-servers 192.168.10.20; option time-offset -25200; pool { allow unknown-clients; failover peer "dhcp-failover"; max-lease-time 86400; range 10.20.0.200 10.20.0.249; deny dynamic bootp clients; } host Server-myserver { option host-name "whatever.ourdomain.com"; hardware ethernet 00:89:D4:35:4F:13; fixed-address 10.20.0.23; } }

  • Network update solutions for a company of ~20 (5 local, 15 remote)?

    - by Margaret
    Hi all This is probably going to be a bit up in the air, because we're still in the "reaching towards solutions" phase, but I figured I'd see what you guys had to say. Plus I honestly know very little about systems and what is good and bad pratice. My organisation has always more or less worked on the concept of local machines; since it primarily employed contractors who were working from home, each of those people was largely responsible for their own machine and backup procedures and the like. We're now expanding, though we're still reasonably small (we're up to about 20 staff members). Most people still work remotely, but we have a central office where about five people are working. But we're getting large enough that we're starting to think it would be a good idea to have a central file server, and things like that - if someone gets hit by a bus, we want someone else to know where to look for the files to continue their work. A lot of the people who work for us remotely work on projects for other companies as well, so I don't want to force them to log in to our server whenever they're on a network. But I do want to make connection to be as painless as possible to do so, to improve utilisation. The other thing is that we're getting more people who would like to remote into the office server and do their work there. Our current remote connection application is an SSH install that allows people access to the network; the problem is, it's a black box to me, and I've never understood how to even connect to it (despite supposedly being de facto sysadmin). Thus far I've been able to bounce questions about how to get it working to the guy who does know it well, but he's leaving the company soon. So we probably need a solution for this that I actually understand. We were knocking around the idea of implementing a VPN with some form of remote desktop, and someone mentioned that this was largely a matter of purchasing a router capable of it; I'm not sure of the truth of that statement. This is what we have in the office: Two shiny new i7 servers, each running Windows Server 2008. Precise eventual layout is still being debated, a little, but the current suggestion is that one is primary database crunching, while the other is a warm backup of the databases, along with running Reporting Services. They currently have SQL Server 2008 installed on them, which is being connected to via the 'sa' account. We're hoping to make each person use their own account (preferably one tied to the 'central' password we set up, so we can use Windows Authentication). An older server, running XP Pro, that we are currently using as a test bed for a project that requires access to older versions of software. This machine is also being used to take backups, but I'm thinking of moving that functionality elsewhere. A spare desktop from a guy who left the company (XP Pro). We're thinking of bumping up the hard disk space and using it as the magical file server that's going to solve one particular everything. Assorted desktops, laptops, etc, at least one for each person in the office (mix of Win XP and Win 7; occasionally a person who normally works remotely might drop in to the office and bring a laptop bearing Vista, but it's pretty rare). All are set up as local user accounts at the moment; I don't know if it's the best arrangement. Purchasing more hardware is not a big problem, but we figure we might as well make use of what we've got first. Is Active Directory a big magic wand that's going to solve all the world's problems? Is there some other arrangement we should be looking to instead?

  • Inserting Newline from XML to Database

    - by blackmage
    I am trying to parse this xml document in which a newline is required for certain fields and must be inserted into the database with the newline. But I've been running into problems. 1)First Problem: \n Character The first problem I had was using the \n like below. <javascript>jquery_ui.js\nshadowbox_modal.js\nuser_profile.js\ntablesorter.js</javascript> The problem was in the database the field came out ot be jquery_ui.js\nshadowbox_modal.js\n... and when output into html it was jquery_ui.jsnshadowbox_modal.jsn............... 2) Then I tried actually having newlines in the xml <javascript>jquery_ui.js shadowbox_modal.js user_profile.js tablesorter.js</javascript> The problem was the output become %20%20%20%20%20%20%20%20%20%20shadowbox_modal.js, and so forth. So how can I get a newline to hold from xml when entered into a database and then output with the newline still?

  • Calcualting Optimal Site to Site Routing using pre-computed times between sites

    - by Idistic
    Assume that I have a number of sites (locations) and the time it takes to travel from each site to each site is pre-computed Example Data - Site to Site Pre-Calculated Times in minutes From Start Site To A 20 To B 15 To C 15 From Site A To B 10 To C 15 Site B To A 10 To C 20 Site C To A 15 To B 20 4 Sites is fairly simple, but what if the site set was say 1000 sites? Given a large site set What would the best approach be to quickly find the optimal routes from the start site while visiting every other site just once? Route Solutions from Start Site for 3 sites from a start site 1 A(20) B(10) C(20) = 50 2 A(20) C(15) B(20) = 55 3 B(15) A(10) C(15) = 40 4 B(15) C(20) A(15) = 50 5 C(15) A(15) B(10) = 40 6 C(15) B(20) A(10) = 45

  • Is it possible to convert a 40-character SHA1 hash to a 20-character SHA1 hash?

    - by ewitch
    My problem is a bit hairy, and I may be asking the wrong questions, so please bear with me... I have a legacy MySQL database which stores the user passwords & salts for a membership system. Both of these values have been hashed using the Ruby framework - roughly like this: hashedsalt = Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{login}--") hashedpassword = Digest::SHA1.hexdigest("#{hashedsalt}:#{password}") So both values are stored as 40-character strings (varchar(40)) in MySQL. Now I need to import all of these users into the ASP.NET membership framework for a new web site, which uses a SQL Server database. It is my understanding that the the way I have ASP.NET membership configured, the user passwords and salts are also stored in the membership database (in table aspnet_Membership) as SHA1 hashes, which are then Base64 encoded (see here for details) and stored as nvarchar(128) data. But from the length of the Base64 encoded strings that are stored (28 characters) it seems that the SHA1 hashes that ASP.NET membership generates are only 20 characters long, rather than 40. From some other reading I have been doing I am thinking this has to do with the number of bits per character/character set/encoding or something related. So is there some way to convert the 40-character SHA1 hashes to 20-character hashes which I can then transfer to the new ASP.NET membership data table? I'm pretty familiar with ASP.NET membership by now but I feel like I'm just missing this one piece. However, it may also be known that SHA1 in Ruby and SHA1 in .NET are incompatible, so I'm fighting a losing battle... Thanks in advance for any insight.

  • IE 7 activex object (or xmlhttprequest?) open method using POST takes 20-30 seconds to return

    - by Toddeman
    i have a problem that only shows itself in IE7. its a simple ajax call. i got my object (accounting for the browser) so in 7 i SHOULD have an ActiveXObject. when i call open with POST, it takes 20-30 seconds to return. i am using a TON of GET calls to populate information and all of these work (finally, after some bug fixing), but i am NOT a web developer so much like the other bugs i had to fix, i figured i was just missing another IE anomaly. this is not a consistent bug either, which makes it harder to find for me. most times the POST functions like it does in Firefox or Chrome, but maybe 1 out of 4 or 5 will take 20-30 seconds to return. it DOES return correctly when it returns, it just takes a long time. am i missing something simple? or is there a smarter way for me to find out exactly what is going on (like the equivalent of the firebug 'net' tab for windows?).

  • How to connect to bluetoothbee device using j2me?

    - by user1500412
    I developed a simple bluetooth connection application in j2me. I try it on emulator, both server and client can found each other, but when I deploy the application to blackberry mobile phone and connect to a bluetoothbee device it says service search no records. What could it be possibly wrong? is it j2me can not find a service in bluetoothbee? The j2me itself succeed to found the bluetoothbee device, but why it can not find the service? My code is below.

    - by Lily
    When I am deserializing a hierarchy I get the following error The input stream is not a valid binary format. The starting contents (in bytes) are The input stream is not a valid binary format. The starting contents (in bytes) are: 20-01-20-20-20-FF-FF-FF-FF-01-20-20-20-20-20-20-20 ..." Any help please? Extra info: public void Serialize(ISyntacticNode person) { Stream stream = File.Open(fileName, FileMode.OpenOrCreate); try { BinaryFormatter binary = new BinaryFormatter(); pList.Add(person); binary.Serialize(stream, pList); stream.Close(); } catch { stream.Close(); } } public List<ISyntacticNode> Deserialize() { Stream stream = File.Open(fileName, FileMode.OpenOrCreate); BinaryFormatter binary = new BinaryFormatter(); try { pList = (List<ISyntacticNode>)binary.Deserialize(stream); binary.Serialize(stream, pList); stream.Close(); } catch { pList = new List<ISyntacticNode>(); binary.Serialize(stream, pList); stream.Close(); } return pList; } I am Serializing a hierarchy which is of type Proxem.Antelope.Parsing.ISyntacticNode Now I have gotten this error System.Runtime.Serialization.SerializationException: Binary stream '116' does not contain a valid BinaryHeader.

  • Voice Recognition Connection problem

    - by user244190
    I,m trying to work through and test a Voice Recognition example based on the VoiceRecognition.java example at http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html but when click on the button to create the activity, I get a dialog that says Connection problem. My Manifest file is using the Internet Permission, and I understand it passes the to the Google Servers. Do I need to do anything else to use this. Code below UPDATE: Ok, I was able to replace my emulator image with one from HTC that appears to come with Google Voice Search, however now when I run from the emulator, i'm getting an Audio Problem message with Speak Again or Cancel buttons. It appears to make it back to the onActivityResult(), but the resultCode is 0. Here is the LogCat output: 03-07 20:21:25.396: INFO/ActivityManager(578): Starting activity: Intent { action=android.speech.action.RECOGNIZE_SPEECH comp={com.google.android.voicesearch/com.google.android.voicesearch.RecognitionActivity} (has extras) } 03-07 20:21:25.406: WARN/ActivityManager(578): Activity is launching as a new task, so cancelling activity result. 03-07 20:21:25.968: WARN/ActivityManager(578): Activity pause timeout for HistoryRecord{434f7850 {com.ikonicsoft.mileagegenie/com.ikonicsoft.mileagegenie.MileageGenie}} 03-07 20:21:26.206: WARN/AudioHardwareInterface(554): getInputBufferSize bad sampling rate: 16000 03-07 20:21:26.256: ERROR/AudioRecord(819): Recording parameters are not supported: sampleRate 16000, channelCount 1, format 1 03-07 20:21:26.696: INFO/ActivityManager(578): Displayed activity com.google.android.voicesearch/.RecognitionActivity: 1295 ms 03-07 20:21:29.890: DEBUG/dalvikvm(806): threadid=3: still suspended after undo (s=1 d=1) 03-07 20:21:29.896: INFO/dalvikvm(806): Uncaught exception thrown by finalizer (will be discarded): 03-07 20:21:29.896: INFO/dalvikvm(806): Ljava/lang/IllegalStateException;: Finalizing cursor android.database.sqlite.SQLiteCursor@435d3c50 on ml_trackdata that has not been deactivated or closed 03-07 20:21:29.896: INFO/dalvikvm(806): at android.database.sqlite.SQLiteCursor.finalize(SQLiteCursor.java:596) 03-07 20:21:29.896: INFO/dalvikvm(806): at dalvik.system.NativeStart.run(Native Method) 03-07 20:21:31.468: DEBUG/dalvikvm(806): threadid=5: still suspended after undo (s=1 d=1) 03-07 20:21:32.436: WARN/IInputConnectionWrapper(806): showStatusIcon on inactive InputConnection I,m still not sure why I,m getting the Connect problem on the Droid.

  • How do you Send More that 20 Parameters to a Stored Procedure Using ODP.Net?

    - by discwiz
    Switching from Microsofts Oracle Driver to ODP.NET version 10.2.0.100. After changing the data types to OracleDBTypes in a procedure, that worked perficetly using System.Data.OracleClient, the procedure fails if we try and pass in more that 20 parameters. The error returned is: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'ADD_TARP_EVENT' ORA-06550: line 1, column 7: PL/SQL: Statement ignorede If we reduce the number of parameters to less than 20 it works. Is this a known issue? Thanks, Dave Here the code for creating the parameters: Shared Function CreateTarpEventCommand(ByVal aTarpEvent As TARPEventType) As OracleCommand Dim cmd As New OracleCommand With aTarpEvent cmd.Parameters.Add(New OracleParameter("I_facID_C", OracleDbType.Char)).Value = .FacilityShortName cmd.Parameters.Add(New OracleParameter("I_facName_VC", OracleDbType.Varchar2)).Value = .FacilityLongName cmd.Parameters.Add(New OracleParameter("I_client_VC", OracleDbType.Varchar2)).Value = .ComputerNameTarpIsRunningOn cmd.Parameters.Add(New OracleParameter("I_TARP_Version_VC", OracleDbType.Varchar2)).Value = .TarpVersionNumber cmd.Parameters.Add(New OracleParameter("I_NAS_Type_VC", OracleDbType.Varchar2)).Value = .FacilityNASSystemType cmd.Parameters.Add(New OracleParameter("I_Aircraft1_Callsign_VC", OracleDbType.Varchar2)).Value = .Aircraft1Callsign If .Aircraft1Type Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_Aircraft1_Type_VC", OracleDbType.Varchar2)).Value = .Aircraft1Type End If If .Aircraft1Category Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_Aircraft1_Cat_VC", OracleDbType.Varchar2)).Value = .Aircraft1Category End If cmd.Parameters.Add(New OracleParameter("I_Aircraft2_Callsign_VC", OracleDbType.Varchar2)).Value = .Aircraft2Callsign If .Aircraft2Type Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_Aircraft2_Type_VC", OracleDbType.Varchar2)).Value = .Aircraft2Type End If If .Aircraft2Category Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_Aircraft2_Cat_VC", OracleDbType.Varchar2)).Value = .Aircraft2Category End If If .SensorShortName Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_Sensor_Name_VC", OracleDbType.Varchar2)).Value = .SensorShortName End If If .TarpConfigurationName Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_TARP_Config_Name_VC", OracleDbType.Varchar2)).Value = .TarpConfigurationName End If If .EntryCreatorID Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_Create_VC", OracleDbType.Varchar2)).Value = .EntryCreatorID End If If .LogAction Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_Log_Action_VC", OracleDbType.Varchar2)).Value = .LogAction End If cmd.Parameters.Add(New OracleParameter("I_TARP_Mode_VC", OracleDbType.Varchar2)).Value = .TarpOperatingMode cmd.Parameters.Add(New OracleParameter("I_Min_Loss_N", OracleDbType.Decimal)).Value = .ClosestMeasureOfLoSS If .MapName Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_MAP_NAME_VC", OracleDbType.Varchar2)).Value = .MapName End If If .TarpConfigurationFileHash Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_CONFIG_HASH_VC", OracleDbType.Varchar2)).Value = .TarpConfigurationFileHash End If Dim aDate As OracleDate = CType(.LossEventsMessages(0).LossEventTime, System.DateTime) cmd.Parameters.Add(New OracleParameter("I_FIRST_LOSS_EVENT_DATE", OracleDbType.Date)).Value = aDate cmd.Parameters.Add(New OracleParameter("I_FIRST_LOSS_EVENT_MS_N", OracleDbType.Int32)).Value = .LossEventsMessages(0).LossEventMilliSeconds If .ZippedMapFiles Is Nothing Then cmd.Parameters.Add(New OracleParameter("I_Map_File_BL", OracleDbType.Blob)).Value = .ZippedMapFiles End If cmd.Parameters.Add(New OracleParameter("I_TARP_Package_BL", OracleDbType.Blob)).Value = .ZippedTarpPackageWithoutMaps cmd.Parameters.Add(New OracleParameter("rs_RESULTS", OracleDbType.RefCursor)).Direction = ParameterDirection.Output End With Return cmd End Function And here is the code for executing the procedure: Dim workingDataSet As New DataSet Dim oracleConnection As New OracleConnection Dim cmd As New OracleCommand Dim oracleDataAdapter As New OracleDataAdapter Try Using oracleConnection oracleConnection.ConnectionString = System.Configuration.ConfigurationManager.AppSettings("MasterConnectionODT") cmd = HelperDB.CreateTarpEventCommand(TarpEvent) cmd.Connection = oracleConnection cmd.CommandText = "LOADER.ADD_TARP_EVENT" cmd.CommandType = CommandType.StoredProcedure Using oracleConnection oracleConnection.Open() Dim aTransation As OracleTransaction = oracleConnection.BeginTransaction(IsolationLevel.ReadCommitted) Try Using oracleDataAdapter oracleDataAdapter = New OracleDataAdapter(cmd) oracleDataAdapter.TableMappings.Add("Results", "rs_Max") oracleDataAdapter.Fill(workingDataSet) ....

  • Perl daemon script for message queue hanging for 20 seconds after each process. Why?

    - by Mike Diena
    I have daemon script written in Perl that checks a database tables for rows, pulls them in one by one, sends the contents via HTTP post to another service, then logs the result and repeats (only a single child). When there are rows present, the first one is posted and logged immediately, but every subsequent one is delayed for around 20 seconds. There are no sleep()'s running, and I can't find any other obvious delays. Any ideas?

  • Do spaces in your URL (%20) have a negative impact on SEO?

    - by Kevin
    All the articles I Googled on this subject are dated back in 2004-2005. Basically I am structuring precanned searches, and it is based off of categories the client will input. Example content/(term name)/index.htm Does it matter if I used the raw term with a space, which is converted to %20 in the URL, or should I convert the link to '-' and remove that before querying for results? I already have it working, but does anyone know if this definitely has a negative impact on SEO and ranking?

  • Ubuntu server has slow performance

    - by Rich
    I have a custom built Ubuntu 11.04 server with a 6 disk software RAID 10 primary drive. On it I'm primarily running a PostgreSQL and a few other utilities that stream data from the web. I often find after a few hours of uptime the server starts to lag with all kinds of processes. For example, it may take 10-15 seconds after log-in to get a shell prompt. It might take 5-10 seconds for top to come up. An ls might take a second or two. When I look at top there is almost no CPU usage. There's a fair amount of memory used by the PostgreSQL server but not enough to bleed into swap. I have no idea where to go from here, other than to suspect the RAID10 (I've only ever had software RAID 1's before).

  • SQL SERVER – Solution – Puzzle – Statistics are not Updated but are Created Once

    - by pinaldave
    Earlier I asked puzzle why statistics are not updated. Read the complete details over here: Statistics are not Updated but are Created Once In the question I have demonstrated even though statistics should have been updated after lots of insert in the table are not updated.(Read the details SQL SERVER – When are Statistics Updated – What triggers Statistics to Update) In this example I have created following situation: Create Table Insert 1000 Records Check the Statistics Now insert 10 times more 10,000 indexes Check the Statistics – it will be NOT updated Auto Update Statistics and Auto Create Statistics for database is TRUE Now I have requested two things in the example 1) Why this is happening? 2) How to fix this issue? I have many answers – here is the how I fixed it which has resolved the issue for me. NOTE: There are multiple answers to this problem and I will do my best to list all. Solution: Create nonclustered Index on column City Here is the working example for the same. Let us understand this script and there is added explanation at the end. -- Execution Plans Difference -- Estimated Execution Plan Vs Actual Execution Plan -- Create Sample Database CREATE DATABASE SampleDB GO USE SampleDB GO -- Create Table CREATE TABLE ExecTable (ID INT, FirstName VARCHAR(100), LastName VARCHAR(100), City VARCHAR(100)) GO CREATE NONCLUSTERED INDEX IX_ExecTable1 ON ExecTable (City); GO -- Insert One Thousand Records -- INSERT 1 INSERT INTO ExecTable (ID,FirstName,LastName,City) SELECT TOP 1000 ROW_NUMBER() OVER (ORDER BY a.name) RowID, 'Bob', CASE WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%2 = 1 THEN 'Smith' ELSE 'Brown' END, CASE WHEN ROW_NUMBER() OVER (ORDER BY a.name)%20 = 1 THEN 'New York' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 5 THEN 'San Marino' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 3 THEN 'Los Angeles' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 7 THEN 'La Cinega' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 13 THEN 'San Diego' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 17 THEN 'Las Vegas' ELSE 'Houston' END FROM sys.all_objects a CROSS JOIN sys.all_objects b GO -- Display statistics of the table sp_helpstats N'ExecTable', 'ALL' GO -- Select Statement SELECT FirstName, LastName, City FROM ExecTable WHERE City  = 'New York' GO -- Display statistics of the table sp_helpstats N'ExecTable', 'ALL' GO -- Replace your Statistics over here DBCC SHOW_STATISTICS('ExecTable', IX_ExecTable1); GO -------------------------------------------------------------- -- Round 2 -- Insert One Thousand Records -- INSERT 2 INSERT INTO ExecTable (ID,FirstName,LastName,City) SELECT TOP 1000 ROW_NUMBER() OVER (ORDER BY a.name) RowID, 'Bob', CASE WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%2 = 1 THEN 'Smith' ELSE 'Brown' END, CASE WHEN ROW_NUMBER() OVER (ORDER BY a.name)%20 = 1 THEN 'New York' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 5 THEN 'San Marino' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 3 THEN 'Los Angeles' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 7 THEN 'La Cinega' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 13 THEN 'San Diego' WHEN  ROW_NUMBER() OVER (ORDER BY a.name)%20 = 17 THEN 'Las Vegas' ELSE 'Houston' END FROM sys.all_objects a CROSS JOIN sys.all_objects b GO -- Select Statement SELECT FirstName, LastName, City FROM ExecTable WHERE City  = 'New York' GO -- Display statistics of the table sp_helpstats N'ExecTable', 'ALL' GO -- Replace your Statistics over here DBCC SHOW_STATISTICS('ExecTable', IX_ExecTable1); GO -- Clean up Database DROP TABLE ExecTable GO When I created non clustered index on the column city, it also created statistics on the same column with same name as index. When we populate the data in the column the index is update – resulting execution plan to be invalided – this leads to the statistics to be updated in next execution of SELECT. This behavior does not happen on Heap or column where index is auto created. If you explicitly update the index, often you can see the statistics are updated as well. You can see this is for sure happening if you follow the tell of John Sansom. John Sansom‘s suggestion: That was fun! Although the column statistics are invalidated by the time the second select statement is executed, the query is not compiled/recompiled but instead the existing query plan is reused. It is the “next” compiled query against the column statistics that will see that they are out of date and will then in turn instantiate the action of updating statistics. You can see this in action by forcing the second statement to recompile. SELECT FirstName, LastName, City FROM ExecTable WHERE City = ‘New York’ option(RECOMPILE) GO Kevin Cross also have another suggestion: I agree with John. It is reusing the Execution Plan. Aside from OPTION(RECOMPILE), clearing the Execution Plan Cache before the subsequent tests will also work. i.e., run this before round 2: ————————————————————– – Clear execution plan cache before next test DBCC FREEPROCCACHE WITH NO_INFOMSGS; ————————————————————– Nice puzzle! Kevin As this was puzzle John and Kevin both got the correct answer, there was no condition for answer to be part of best practices. I know John and he is finest DBA around – his tremendous knowledge has always impressed me. John and Kevin both will agree that clearing cache either using DBCC FREEPROCCACHE and recompiling each query every time is for sure not good advice on production server. It is correct answer but not best practice. By the way, if you have better solution or have better suggestion please advise. I am open to change my answer and publish further improvement to this solution. On very separate note, I like to have clustered index on my Primary Key, which I have not mentioned here as it is out of the scope of this puzzle.

  • Oracle pl\sql question for my homework in oracle 11G class [migrated]

    - by Bjolds
    I am new to oracle 11G programming and i have run into a tough situation with pl\sql funtions and automation. I ame unsure how to create the function for the automation of Registration system for a College registration system. Here is what i want to do. I want to automate the registrations system so that it automaticly registers students. Then I want a procedure to automate the grading system. I have included the code that i am written to make most of this assignment work which it does but unsure how to incorporate Pl\SQL automated fuctions for the registrations system, and the grading system.
