SQL errors in 1.2.2 ?
-
Hi,
Server Platform: Windows Server 2008 R2 standard (64bit)
NetXMS Server: netxms-1.2.2-x64Since upgrading to 1.2.2 I'm having intermittent problems viewing graphs of DCI values and getting DCI collection failures in the client. In the server system log I get a number of entries when the DCI collection fails:
SQL query failed (Query = "INSERT INTO event_log (event_id,event_code,event_timestamp,event_source,event_severity,event_message,root_event_id,user_tag) VALUES (?,?,?,?,?,?,?,?)"): constraint failed
SQL query failed (Query = "INSERT INTO event_log (event_id,event_code,event_timestamp,event_source,event_severity,event_message,root_event_id,user_tag) VALUES (?,?,?,?,?,?,?,?)"): constraint failed
SQL query failed (Query = "INSERT INTO event_log (event_id,event_code,event_timestamp,event_source,event_severity,event_message,root_event_id,user_tag) VALUES (?,?,?,?,?,?,?,?)"): column event_id is not unique
SQL query failed (Query = "INSERT INTO event_log (event_id,event_code,event_timestamp,event_source,event_severity,event_message,root_event_id,user_tag) VALUES (?,?,?,?,?,?,?,?)"): constraint failed
SQL query failed (Query = "INSERT INTO event_log (event_id,event_code,event_timestamp,event_source,event_severity,event_message,root_event_id,user_tag) VALUES (?,?,?,?,?,?,?,?)"): column event_id is not unique
SQL query failed (Query = "INSERT INTO event_log (event_id,event_code,event_timestamp,event_source,event_severity,event_message,root_event_id,user_tag) VALUES (?,?,?,?,?,?,?,?)"): constraint failed
I then restart NetXMS Core and its ok again for a while before failing again with the same problem.
Any pointers on where I should be looking would a great help.

Hi!
Looks more like a bug. What database you are using and what driver?

Hi!
Check netxmsd.conf file, DBDriver parameter.

Guys... Just a reminder or in case you are not aware. Please do not use SQLite for production. SQLite is not designed to handle big data volumes or a high DB load. Don't get me wrong, SQLite is still a great DB engine and does very well what its designed for. But it's just not up to the task for an average NetXMS production environment. Use NetXMS with SQLite for trying out, testing new features or if you monitor home network with 3 nodes
But stay away from it in the production!!! You will be really better off with MySQL, Postgres or Oracle.As for the topic. There is a fix for this specific problem committed yesterday. Well, actually this is a work around some obscure SQLite behaviour (see warning above!). It will go into 1.2.3. If you need it faster feel free to get it off the svn and test

Hi!
There are export/import option in nxdbmgr. What it basically does is exporting data from your existing database into SQLite database file, and the importing into another database. As you have SQLite already, you can try to just create empty database on another engine, create correct netxmsd.conf, and the use your existing database file as input for nxdbmgr import command.

Hi,
I have now installed MySQL Community Server 5.5.27 (x64), re-installed NetXMS to include MySQL client support. I setup MySQL database thus:
mysql> CREATE DATABASE netxms;
mysql> GRANT ALL ON netxms.* TO netxms@localhost IDENTIFIED BY 'password'netxmsd.conf:
---------------------------------------------------------------------------------
#
# NetXMS Server configuration file
# Created by NetXMS Server configuration wizard at Wed May 09 15:31:46 2012
#LogFile = {syslog}
DBDriver = C:\NetXMS\bin\mysql.ddr
DBServer = localhost
DBName = netxms
DBLogin = netxms
DBPassword = password
LogFailedSQLQueries = yes
---------------------------------------------------------------------------------I initialised the database using:
nxdbmgr.exe init C:\NetXMS\lib\sql\dbinit_mysql.sql
then I tried importing the existing configuration and history using:
mxdbmgr.exe import C:\NetXMS\database\bn-netxms
this results in the following output:
-------------------------------------------------------------------------
NetXMS Database Manager Version 1.2.2WARNING!!!
This operation will clear all configuration and collected data from database.
Are you sure? (Y/N) Y
Database successfully cleared

-------------------------------------------------------------------------The import generates an exception, logged as follows:

Hi!
Just try to reproduce the error on my system, but without success. Is it possible to send me your SQLite database because I suspect that some combination of data causes this crash. If it violates your security policy, we will find other ways to debug it.

Sure. Send it to [email protected].
