Disk i/o error sqlite3

disk i/o error sqlite3

OperationalError: disk I/O error During handling of the above exception, I don't know where sqlite puts its files, in particular the temporary journal. That sounds like a problem with the shared drive arrangement, rather then one specific to sqlite. It would be worth stating which virtualisation method you are. When I've seen this, it's due to SQLite trying to write to a non-local volume. PhotoStructure runs SQLite in WAL mode, which requires a file.

    [SQLite] cannot execute select-statement: disk i/o error (10)

    Hello,

    The problem was in the title "cannot execute select-statement: disk i/o error (10)"

    I use the DLL sprers.eu ()

    And I have this error for some users (a few of them but the problem is that I don't know how to fix it)

    Anyone have any idea about this problem?
    Thanks a ton !

    Re: [SQLite] cannot execute select-statement: disk i/o error (10)

    As I wrote this only happens to very few users. maybe like 2% .
    My code seems normal :

    Code:

    If Cnn Is Nothing Then MsgBox "error", vbCritical + vbApplicationModal: Exit Sub Dim SQL As String SQL = "SELECT ID,Name FROM Team ORDER BY Name" Dim RS As cRecordset Set RS = sprers.eucordset(SQL) If Err Then MsgBox "SQL:" & SQL & vbCrLf & sprers.euptionf & vbCr & sprers.euError: sprers.eu: Exit Sub

    or

    Code:

    Dim SQL As String SQL = "SELECT ID,date,Caption,color FROM Memory WHERE date BETWEEN ? AND ? ORDER BY date" Dim RS As cRecordset Dim Sel As cSelectCommand Set Sel = sprers.euSelectCommand(SQL) With Sel .SetShortDate 1, d0 .SetShortDate 2, d1 Set RS = .Execute End With Set Sel = Nothing Dim oSheetWrng As oWarning Do While sprers.eu = False Set oSheetWrng = New oWarning disk i/o error sqlite3 = RS![Date] sprers.eu = RS![ID] sprers.eu = RS![Color] sprers.euon = RS![caption] sprers.euning oSheetWrng Set oSheetWrng = Nothing sprers.euxt Loop Set RS = Nothing

    the database is mostly on a shared disk

    Re: [SQLite] cannot execute select-statement: disk i/o error (10)

    sounds like there is no valid Connection to the Database

    also your CommandParameters looks strange

    here a sample disk i/o error sqlite3 Parameter.

    Code:

    Private Sub Command5_Click() Dim Parm1 As New sprers.euter Dim Parm2 As New sprers.euter If sprers.eudText = "" Then sprers.euConnection = cn With cmd 'PARAMETERS KW Long, FJahr Long; .CommandText = "SELECT sprers.eu_ID As [Lfd-Nr], sprers.eu_Datum As Datum, sprers.eu_KW AS Adobe reader c runtime error, sprers.eu_Tag As Tag, sprers.eu_Uhrzeit As Uhrzeit, sprers.eu_Tagbez " & _ "FROM tbl_Jahr INNER JOIN ZeitMeldung ON tbl_sprers.eu_ID = sprers.eu_JaID " & _ "Where Format(ZE_Datum, 'm')=? " & _ "And Format(ZE_Datum, 'yyyy')=? " & _ "GROUP BY sprers.eu_ID, sprers.eu_Datum, sprers.eu_KW, sprers.eu_Tag, sprers.eu_Uhrzeit, sprers.eu_Tagbez, Format([ZE_Datum],'m')" End With 'Parameter 1 = KW With Parm1 .Type = adInteger .Size = 4 .Direction = adParamInput .Value = Text1 sprers.eu Parm1 End With 'Parameter 2 = Jahr With Parm2 .Type = adInteger .Size = 4 .Direction = adParamInput .Value = Text2 sprers.eu Parm2 End With End If sprers.euters(0).Value = Text1 sprers.euters(1).Value = Text2 Set Rs = sprers.eue() If sprers.euCount Then Call FillGridJahr(Rs) End If If sprers.euCount = 0 Then sprers.eu End If Set Rs = Nothing End Sub

    Re: [SQLite] cannot execute select-statement: disk i/o error (10)

    Dilettante's link in Post #11 is 13 years old and no longer accurate. Concurrency in SQLite has come a long way since then (see the WAL mode documentation here: sprers.eu). Not saying it's perfect or anything. but it's better than is being claimed here.

    Dlitantte is right about avoiding SQLite over a network shared drive though. It is not recommended as per the Sqlite documentation. Sometimes it works, disk i/o error sqlite3, other times it doesn't, and when it doesn't bad things can happen.

    Instead you might consider creating an intermediary server application that handles requests from your client software and performs SQL commands autocad menu utilities loaded. error function cancelled locally stored databases. I have been using this approach for many years now in multi-user scenarios with no reported database issues. See this excerpt from sprers.eu

    Server-side database

    Systems designers report success using SQLite as a data store on disk i/o error sqlite3 applications running in the datacenter, or in other words, using SQLite as the underlying storage engine for an application-specific database server.

    With this pattern, the overall system is still client/server: clients send requests to the server and get back replies over the network. But instead of sending generic SQL and getting back raw table content, the client requests and server responses are high-level and application-specific. The server translates requests into multiple SQL queries, gathers disk i/o error sqlite3 results, does post-processing, filtering, and analysis, then constructs a high-level reply containing only the essential information.

    Developers report that SQLite is often faster than a client/server SQL database engine in this scenario. Database requests are serialized by the server, so concurrency is not an issue. Concurrency is also improved by "database sharding": using separate database files for different subdomains. For example, the server might have a separate SQLite database for each user, so that the server can handle hundreds or thousands of simultaneous connections, but each SQLite database is only used by one connection.

    Lastly, here's an anecdote that is contrary to what Diletantte's "robustness" claims disk i/o error sqlite3 Jet/ADO. A legacy version of my software from many moons ago used Jet/ADO and users encountered occasional errors when databases were stored on a network drive. Happened enough that there was a "Repair" option in the File menu that would attempt to fix mildly corrupted databases, but even that failed a couple of times and users had to restore from backup. This hasn't happened even once with the client/server/SQLite implementation. YMMV of course.

    Nope, my mileage does not vary from yours.

    SQLite, when disk i/o error sqlite3 in a true Client/Server-Setting (behind the MS-WebServer (IIS), or other WebServers - or the vbRichClient-RPC-Classes, or COM+)
    shows very good concurrent behaviour (far better than ADO/JET, which does not even support concurrent reads)
    In my tests SQLite in such an AppServer-setting was much faster than even the MS-SQLServer (with concurrent Reads).

    @dilettante
    Your dislike of *any* kind of OpenSource-library is not really comprehensible to me.
    Discouraging VB6/VBA developers who try to decouple from MS-libs/dependencies is in my opinion irresponsible at this point of time,
    especially when we talk about SQLite, which is one of the finest pieces of Software ever written (having one of the broadest Test-Coverages known to man).

    SQLite is the "quasi-standard" for App-DBs on this planet (it is used on PCs and mobile-devices anywhere, and from
    nearly any imaginable programming-language) - and that for very good reasons (performance and stability being only two of them)
    So it's "us VBers" who are the exception here - not the other way around.

    @christ62
    What you encountered are "Network-protocol-errors" (happening on the "input/output-channel" to the "Remote-Disk" - meaning, it's finally a socket-protocol which fails).
    Because when you work against a "mapped drive" (a Network-Share), you are not working directly against a local disk i/o error sqlite3 of course (which has a much shorter -
    and much more reliable connection over SATA/SCSI or PCIe cables or channels).

    Communication with "remote-drives/shares" happens per sockets over SMB/CIFS in the Windows-world (sprers.eu=vs).aspx) -
    and SQLite relies on "transparently supported FileLocking" when such Network-Protocols are used (to manage concurrent DB-Access from Clients in a LAN).

    And these network-protocols might fail (e.g. due to a "pairing" which runs slightly different versions of SMB/CIFS) -
    or you get Network-dropouts for other reasons (WLAN-connections for example, or failures in Switches or Routers).

    So I would encourage you, to put your SQLite-DBs behind a dedicated ServerHost, which runs one of the above mentioned AppServers.

    If you have questions about implementing VB-Code for such a scenario, just ask
    (setting up SQLite-DBs for "AppServer-mode" is not as difficult as it sounds).

    Re: [SQLite] cannot execute select-statement: disk i/o error (10)

    Gee, a debate over databases that has spilled over into the even longer running open source debate. This is one that seems unlikely to ever fade, but let's keep it impersonal.

    There are a few additional points I would add:

    In this very thread, there is one person who saw issues with Jet/ADO (jbpro), while one person reported a long-running mdb that had no issues (DEXWERX). I have a foot in each camp. I have a few very long running applications based on Jet and an MDB. I've had issues, but only three or four in twenty years. So, there were issuesbut they were rare. I wouldn't use an Access database for multiple users over a network due to the issuesbut it would the issues obviously aren't all that big.

    One other point I'd clear up is that SQL Server Express is free, so that's also an option to put out there.

    Open source is an interesting thing. I use some, such as LibreOffice, but I also use SQL Server Express, so I'm no True Believer. I've seen plenty of projects come and go (Open Office has done both, perhaps more than once). I would guess that the percentage of users of open source stuff who contribute in either code or money is REALLY small. I'd be surprised if it disk i/o error sqlite3 10%. So, open source tends to be a labor of loveand love fades all too often. Somebody (I'm not feeling like reading through this thread one more time for one more correct attribution) suggested that they move away from MS after being burned by the abandonment of VB6, but I would argue that open source often has no more longevity, and often has less. For all that people love to hate MS, you still have VB6, programs written in it still run, the IDE still works on the new OS, though nearly 20 years have passed since the last version, disk i/o error sqlite3, and it looks like it will still work for at least another decade. That's incredible longevity in this industry. We can't even be certain what hardware we'll be using in 10 years, and we certainly can't be certain that any single open source project we use will still be a going thing in ten years.

    Change happens. Nowhere more so than in tech. You take a guess at the future and bet on it, but if the world shifts out from under you, don't be bitter about it, it's not personal.

    My usual boring signature: Nothing

    I can't see any "longer running OpenSource-debate" here
    I mentioned the term once in my post #21 -
    and the only other usage of the term (until your post above) was by Dexwerx's reply (#22), expressing "his love for it"
    So, no - cannot find any error mumaker 1.07 about OpenSource so far

    while one person reported a long-running mdb that had no issues (DEXWERX).

    There's no contradiction, because Dexwerx "long-running mdb" was not sitting "behind a Network-Share" (as in jpbro's case),
    but behind an *.asp-WebServer (the MS-IIS), which then in turn plays "DB-Server" (allowing the MDB in question, to work against a local disk == "much more stable").

Connector Service Fails to Start with Disk I/O Error

 

Cause

 

Upon launching the NetBackup SaaS Protection (NSP) Connector Service, the error below is shown:

 

 

Restarting the service does not help nor does uninstalling/reinstalling the application.  

 

The Connector Service log (sprers.eu) shows the error below.  

This log can be found in the following path:  C:\Users\hubstorsvc\AppData\Roaming\sprers.eutorService

 

 

Cause

This issue is very infrequent and there has been no root cause defined disk i/o error sqlite3 of yet.

 

Solution

Running the following query against the DB seems to clear up the issue:   pragma integrity_check;

This can be done by using either of the following utilities:

  1. DB Browser for SQLite: sprers.eu
  2. Using sprers.eu from SQLite tools: sprers.eu

Note: it has been reported that running this check needs to be done more than once.  

disk I/O error with SQLite3 in Python 3 when writing to a database

i am a student just starting out with python, and i was tasked with creating a relational database management system. I think i came pretty far, but i seem to have hit a wall. This is my code:

import csv import sqlite3 conn = sprers.eut('sprers.eu') c = sprers.eu() sprers.eue('''CREATE TABLE unfccc ( Country TEXT, CodeCountryFormat TEXT, NamePollutant TEXT, NameYearSector TEXT, NameParent TEXT, Sector TEXT, CodeSector TEXT, CNUEDSPD TEXT )''') def insert_row(Country, CodeCountryFormat, disk i/o error sqlite3, NamePollutant, NameYearSector, NameParent, Sector, CodeSector, CNUEDSPD): sprers.eue("INSERT INTO unfccc VALUES (?, ?, ?, ?, ?, ?, ?, ?)", (Country, CodeCountryFormat, NamePollutant, NameYearSector, NameParent, disk i/o error sqlite3, Sector, CodeSector, disk i/o error sqlite3, CNUEDSPD)) sprers.eu() with open('UNFCCC_vcsv') as csvfile: readCSV = sprers.eu(csvfile, delimiter='t') counter = 0 for row in readCSV: insert_row(row[0], row[1], row[2], row[3], disk i/o error sqlite3, row[4], row[5], row[6], row[7]) counter = counter+1 print('%d down, more to go' % counter) sprers.eu()

when i run it with line 4 directing the input towards :memory: it works perfectly and i have myself what i think is a relational database.

However, when i try to run the code like this, disk i/o error sqlite3, writing the data to a db file, i get this error:

File "<ipython-inputcbc>", line 19, in insert_row sprers.eue("INSERT INTO unfccc VALUES (?, ?, ?, ?, ?, ?, ?, ?)", (Country, CodeCountryFormat, NamePollutant, NameYearSector, NameParent, Sector, CodeSector, CNUEDSPD)) OperationalError: disk I/O error

I&#;ve searched stackoverflow, and i&#;ve used google, but i don&#;t think any of the cases i found match up to what i&#;m trying to do here (or i don&#;t have the knowledge to figure out whats going on). One other thing i noticed about my code is that it inputs the data into memory super fast, but when i write to a db file it is really slow, it shouldn&#;t be a hardware limit as i am using an SSD. Any help will be greatly appreciated!

Answer

Setting Backup/Sync to pause on the system tray icon while working with a project stored on Google Drive will prevent disk i/o errors.

This is because when the file is written to or changed, backup & sync attempts to upload the new version to your Google Drive, while it is doing this; the file becomes a &#;Read-Only&#; file.

While sync is paused your Google Drive folder acts more like a normal directory.

disk I/O error in SQLite

What are the possible things that would trigger the "disk I/O error"? I've been having this problem and I couldn't find a solution. I have a SQLite3 database, and I'm trying to insert data from a file that contains SQL inserts.

Sample data in the file:

I tried inserting that in the db file with the following command:

See below the error that I get:

The input lines that don't generate error are successfully included, disk i/o error sqlite3, but I don't understand why some lines have errors, and they are not inserted into the DB. There's nothing special in the lines with error, and if I run the command again I get errors in different lines, which means it's random (not related to the data itself). I tried adding andto no success. I'm running that on a lubuntu, which runs in a VirtualBox virtual machine. The host machine is a windows 7. The pwd of the files is a shared folder, i.e., it's a folder in the host machine. If I run it in a "local folder" in the guest machine, the error doesn't happen, although for some reason it's much slower In any case, I'd like to know about the I/O error.

How to reduce the Log Level generated in RE/CE?

Hello Guys,

I have developed a comparison tool using Talend, which will compare 2 huge SQLite Database (80GB each) and store the compared result in another System error 14001 has occurred Database.

Problem:

1) The tool is unable to read Input SQLite fileif size is beyond 2GB as it shows an error "sprers.eueption: database disk image is malformed", but if the file size less then that it works, have checked the Integrity (OK) and it also opens with SQLite tool. So for now I moved to Disk i/o error sqlite3 file as Input.

2) But after comparing when I wanted to store the result in SQLite Database it shows "sprers.eueption: disk I/O error" after reaching to a disk i/o error sqlite3 size close to 2GB. I have checked the server size its GB free and 16GB RAM available.

Any suggestion what can be done?
