Another process has added/updated/deleted the ‘{0}’ record. Your changes will be lost.

Hi There, Today want to discuss with you how what is ” Another process has added/updated/deleted” error and how to investigate/fix it. Why it happens? Let’s start with error understanding. Actually, this error comes from potential differences between user copy of data and actuals in database. Before I jump into details I want to remind you few architectural points about Acumatica: Acumatica commits records one by one in most cases. For several records update statement will be executed multiple times. Also Acumatica stores the data needed to be save inside in-memory user specific cache. So it is possible that 2 users may have several versions of the same record with… Read more

Disaster Recovery vs Failover

Hi All, Today want to speak with you about protecting your ERP from accidents. There are 2 possible way to protect you application from disaster, which are different by approach and recovery time: Disaster Recovery (DR) – involves a set of policies, procedures and tools to enable the recovery infrastructure and systems following a natural or human-induced disaster. So basically disaster recovery assumes that disaster can happen and we just need to recover it as soon as possible. Failover Protection – is automatic switching to a redundant computer server, system, hardware component or network upon the failure. Failover basically assume that stability of the system should not be affected by… Read more

Optimizing Large Import

Hi All Want to share with you some good approaches to Import a large amount of data. If you ever tried to import some large set of data from Excel you actually know that it is not as fast as importing data into the SQL table.

Reset User Password

Hi Everyone, In Acumatica all passwords are stored as a Hash, so even if you get database, you are not able to login with user password. But in case of trouble you can reset it to new one directly in the database. Just execute this query against the sql: UPDATE Users SET Password = ‘123’, LockedOutDate =null WHERE Username = ‘admin’ Don’t worry about clear text password – Acumatica will automatically calculate new hash on first login operation. LockedOutDate is field where system stores last unsuccessful login attempt date-time. So if your user is locked out you can use this statement to unlock it. Thank you!

Analyze Running Queries on Database

Hi Everyone. If you face database performance issues, you might need some way to get running queries from there. SQL profiler is good, but some times you do not have it or you don’t have access to it. But if you can run SQL queries, you can use this script. It will show you immediate snapshot of all running queries. Script: View the code on Gist. If you are searching for statistical information you can use that query. This one will show you to 30 heaviest queries on the sever. Script: View the code on Gist. Have a nice development!

Log Exceptions with First Chance Excetion Log

Hi All Microsoft .Net has a very nice feature like First Chance Exception Log. You can easily use it in your Acumatica to log specific exceptions. Read more about first chance exceptions. Now I want to share with you my logger example: Logger example: View the code on Gist. To to enable this logger, you just need to put an additional file to <SitePath>App_code folder and add this line to your global.asax file: void Application_Start(object sender, EventArgs e) { ….. SessionLogger.Initialise(); ….. } Based on this idea I have created a logger that catchs “Session Expired” messages for monitoring purposes. The source code of SessionLogger is available on GitHub.
