Hello guys, today, I am going to share one small but the useful tip about logging in to your Java application. If your Java application is a weekly restart, I mean it starts on Sunday and not again on the weekday, then you really want to have separate log files for each day. This helps during troubleshooting and debugging. But If you are facing a problem where your log files are not rolling daily and becoming bigger and bigger after each passing day, making it challenging to search anything in case of any production issue, then it might be that you have not configured your Log4j properly to roll your logs daily.
How to solve Arithmetic overflow error converting IDENTITY to data type tinyint, smallint or int in Microsoft SQL Server database
Last year we had a production issue where one of our backup jobs was failing while inserting Orders aggregated from other systems into our SQL Server database. The reason was dreaded "Arithmetic overflow error converting IDENTITY to data type int" because the table was using IDENTITY feature of SQL Server to generate OrderId, and Identity has breached it a maximum value, which is around 2.1 billion, precisely 2,147,483,647. The error "Arithmetic overflow error converting IDENTITY to data type int" comes when the IDENTITY value is inserted into a column of data type int, but the value is out-of-range. For example, if the current value of Identity becomes more than 2,147,483,647, then you cannot store that into an int column because it's more than the maximum value of int in SQL Server.
How to Fix java.lang.OutOfMemoryError: Metaspace in Java? [Solution]
Hello guys, An OutOfMemoryError related to Metaspace indicates that your Java application has exhausted the memory allocated for the Metaspace area, which is used for class metadata and method information. This error typically occurs when an application dynamically generates and loads a large number of classes or when the Metaspace size is not properly configured to handle the application's requirements. Java class metadata (the virtual machine's internal presentation of Java class) is allocated in native memory (referred to here as metaspace). If metaspace for class metadata is exhausted, a java.lang.OutOfMemoryError exception with a detail MetaSpace is thrown.
