Do wait_timeout session clear all running session or only sessions which are in SLEEP mode for specified seconds ?

On MySQL 5.7. I would like to prevent all alter table scripts \ update scripts that are taking longer than 10 minutes to run. Is it possible? I've tried to set **MAX_EXECUTION_TIME** and it does work but only for SELECT queries. I still could execute a long update\alter query.

We can use SET MAX_EXECUTION_TIME=10; statement to stop the execution of a SELECT statement, if it took more than 10 milliseconds to execute the query. But the same wont work for other statements like CREATE TEMPORARY TABLE and INSERT etc. Reference: https://dev.mysql.com/doc/refman/5.7/en/optimizer-hints.html#optimizer-hints-execution-time Currently my temporary table creation takes more than 50s to complete. I want to put a limit like 10s. Is it possible in MySQL?

My SQL Server version is 2012 R2. I have one publishing machine with several publications, one distribution machine, and several subscription machines. Everything is working fine. However, when I try to add a new subscription on one of the publishers (The size of this database is close to 150 GB) and start the agent to create a snapshot, it gives me the following error message when it reaches 99%, Based on the information provided, there are some indications of query timeouts. I checked the setting: Property -> Connection -> Remote Query Timeout value 0,which means there is no limit for the duration of remote queries. plz advise, thanks all!

My understanding is that PostgreSQL functions are executed similar to a transaction. However, when I tried to "SET LOCAL statement_timeout" within a function, it did not work. Here's how it works within a transaction: BEGIN; SET LOCAL statement_timeout = 100; SELECT pg_sleep(10); COMMIT; where the results are (as expected): BEGIN SET ERROR: canceling statement due to statement timeout ROLLBACK However, if I put the same commands within a function body: CREATE OR REPLACE FUNCTION test() RETURNS void AS ' SET LOCAL statement_timeout = 100; SELECT pg_sleep(10); ' LANGUAGE sql; SELECT test(); the timeout does not occur, and the function test() takes 10 seconds to execute. Please advise on why the two cases differ, and how I can correct it to set statement timeouts within a function.

My table consists of the following columns: job_id, event_type, timestamp, client_type, role_type, Every job_id has record of which event_type (example login, edit, delete) , what timestamp, which role did the event (system, master, agent) and which client it happened. My query is that I want to find the list of job_id that DO NOT have a login event BUT have a DELETE event and acted by the system I tried a simple query using only one condition (have a loggedin event), but the DB times out/ lost connection. Is there anything I could do? SELECT job_id FROM table.events WHERE wa_id NOT IN (SELECT wa_id FROM table.events WHERE event_type = 'LoggedIn' ) AND role_type = 'MASTER' AND YEAR(timestamp) = '2023' AND platform_id = '1';

I understand that I can set the value of the global MAX_EXECUTION_TIME by running (from mysql client): SET GLOBAL MAX_EXECUTION_TIME But how do I just inquire its value? GET instead of SET does not seem to accomplish that.

I've done my best to follow https://dba.stackexchange.com/questions/204565/why-is-my-query-suddenly-slower-than-it-was-yesterday The ShowPlanXML parses fine with SQL Sentry Plan Explorer but not via brentozar.com/pastetheplan (not sure why) so I have pasted text files to my github instead below: Here is the DDL and TSQL I am executing. Here is the bad query plan (times out). PasteThePlan Here is the good query plan. PasteThePlan Any idea how I can more reliably get the engine to use a "good" query plan? Thank you!

I have an API endpoint that runs a query. For some reason, when I hit the production endpoint the query times out (after 2 minutes) but when I hit the same endpoint locally with my local environment connected to the same production DB the query runs in a couple of seconds. Is there a reason why this might happen? The issue is definitely not a connectivity issue because when I hit the same endpoint (on prod) with a different token it doesn't timeout. It's only some tokens that timeout on prod (yet when I run it locally connected to my prod DB it runs in a couple of seconds)

I have encountered a query timeout ("Execution Timeout Expired") on a sub-second query on a connection set to 30 seconds timeouts. Client side logging indicated that 4 days elapsed between submitting the query and receiving the timeout. The client and the server were both running as part of the same virtual machine. The root cause was fairly evident: the virtual machine, having been suspended over several days, synchronized its system time via NTP and jumped 4 days ahead in time and the system time adjustment propagated to SQL Server just as it was executing the unfortunate query. However, this incident got us thinking. **Can transitions to daylight saving time cause random query timeouts, by spuriously adding 1 hour to the measured execution time of the query?** **Can other time zone changes cause random query timeouts?** I am hoping that SQL Server would use UTC timestamps to detect query timeouts and thus be unaffected by time zone changes. But I am unable to find any documentation to this effect.

I have multiple users in Postgres. I would like to set up different statement timeouts for different users. Eg: Guest 5 minutes and Admin 10 minutes. Is it possible in Postgres 11.11?

Recently I have noticed that a job is failing on our Production 2014 SQL Server with this error text: > Timeout error . [SQLSTATE 42000] (Error 258) OLE DB provider "SQLNCLI11" for linked server "LinkedTestServer01" returned message "Login timeout expired". [SQLSTATE 01000] (Error 7412) OLE DB provider "SQLNCLI11" for linked server "LinkedTestServer01" returned message "Unable to complete login process due to delay in login response". [SQLSTATE 01000] (Error 7412). The step failed. The job fails during random times of the day and night. Sometimes even overnight (2am or 3am) - The connection timeout and remote query property in the linked server property is set to 0. - The Remote login Timeout property on the server itself is set to 10. - I have been monitoring the server using Activity Monitor and DMV queries and am not seeing any blocking or deadlocks. - There are no errors in windows event log or SQL error log that shows any timeout errors. - Index maintenance is running nightly and there are no index fragmentation in the corresponding databases. - There are no spikes in CPU. CPU does not go above 20% even during the busiest times of the days. - There are no memory issue. Memory stays at a steady 88%. In this scenario, what are the other ways I can find the root cause of this timeout error? If you have faced this situation before, what did you do to solve this issue?

Is there a DMV or other mechanism available that returns the command timeout for an executing session_id?

I use SQL Server 2008 R2 and ASP.NET 4.5. Sometimes, I get this error when I executed a complex procedure: > System.Data.SqlClient.SqlException > > Timeout expired.

I am trying to if confirm query timeout in Azure. Our frontdoor is reporting a 503 response at 30 Seconds response, as its the SQL server default value, I am trying to confirm if these are indeed query command timeouts. I've searched for "Timeout" in the Logs section of the portal monitoring (not sure this how they would be represented) Is there an method to locate query timeouts in Azure? Answers or links with a decent resource would be highly appreciated as my searches are not proving fruitful at the moment

We experienced an issue in which a read-only query, run through MySQL workbench, timed out from a user's UI perspective and remained running on the server (and apparently consuming more and more resources) until we had an outage. Questions - Is there a standard way to deal with this sort of issue in MySQL? - Is there a fundamental cause that we need to avoid?

We have two separate SQL Servers. On one server we have a data warehouse (DWH), on the other we have sales information database. Now on the DWH server there is an ETL job that collects the information from the sales server. The job runs daily after midnight. The DWH collects the information via linked server from the sales database. Now, the most time the ETL job runs without any problems. But sometimes it fails because of query timeout. We have found out, that there is a specific pattern: The failure happens every 11th day. So on the 11th day the ETL job fails to collect information. The following error occurs: > SQLNCLI11 for linked server “my linked server” returned message “Query timeout expired.” Note: The job fails usually 10 minutes after start. We have searched everything and could not found out what this issue causes. Also we know that the amount of data is every time, almost the same. Also there is no any scheduled job that runs all 11 days or something. The remote query timeout on the linked server is set to 0. Our next step will be, to turn off the antivirus programm on the sales server, to check if this causes the problem. Does anyone have any clue or idea, where i can search further to find the problem?

SQL Server 2008 SP3 How do I track down these timeout errors ? The errors are displayed on an intranet dashboard used specifically for error reporting in IIS. My suspicion is that there is a default timeout of 30 seconds in the web application and if a query takes more than thirty seconds, an exception is thrown. As there are many queries that take longer than 30 seconds on these SQL servers, I can't just filter in profiler based on duration. Serving up the website being monitored by this dashboard are two IIS servers retrieving data from seven SQL Server instances. Could I use the **"User Error Message Event"** and the **"OLEDB Errors Event"** to track these errors in SQL Server Profiler?

**Without changing the settings on servers**, etc to the linked server connections, etc, is there a way to catch the dreaded? > "OLE DB provider "SQLNCLI10" for linked server "[Some Server here]" returned message "Query timeout expired"" > > "OLE DB provider "SQLNCLI11" for linked server "[Some Server here]" returned message "Query timeout expired"" and either have the procedure retry to run or continue on to the next process in a cursor? We have a dynamic SQL Server system set up to call procedures based on a specific process we're running. This works fine but every once in a while, one of the steps will throw the above error and of course a traditional Try...Catch block doesn't capture it. I've searched for several hours on this and I need a way to be able to "capture" this error and either retry the procedure or skip the procedure but not exit the cursor (so go to the next process in line). We have a 2016 and a 2008 R2 servers communicating with each other. Right now we have a single cursor running with 20 such steps in it (we are trying to use this as a job task replacement) but eventually we will have 30 or 40 processes, with tasks totaling well into the hundreds using this system. Please let me know if you have any ideas.
