PSQLException: current transaction is aborted, commands ignored until end of transaction block

How to Fix the PSQLException: current transaction is aborted Error

Are you getting the frustrating PSQLException: current transaction is aborted, commands ignored until end of transaction block error in your JBoss application? Don't worry, we've got you covered! This error usually occurs when there is a problem with the transaction management in your PostgreSQL database. In this blog post, we will dive into the common causes of this error and provide you with easy solutions to help you get back on track. Let's get started!

Common Causes of the Error

1. Incorrect SQL Statements or Missing Tables: One possible cause of this error is when your application is trying to execute SQL statements that are incorrect or referencing non-existent tables. In the provided context, the error occurs when Infinispan tries to run a SELECT count(*) statement and then a CREATE TABLE statement, but the first statement fails and causes the transaction to be aborted.

2. Conflicting Transactions: Another common cause is when there are conflicting transactions in progress. This can happen if your application is trying to execute multiple SQL statements within the same transaction, and one of the statements fails, causing the entire transaction to be aborted.

3. Locking or Deadlock Issues: Locking or deadlock issues can also lead to this error. If your application is trying to access locked resources or if there is a deadlock situation between multiple transactions, the current transaction may be aborted.

Easy Solutions to Fix the Error

Now that we understand the possible causes of the PSQLException: current transaction is aborted error, let's explore some easy solutions to resolve it.

1. Check for SQL Errors: Start by reviewing your SQL statements and make sure they are valid and referencing the correct tables. In the provided context, look for any typos or missing tables in the SELECT count(*) statement and the subsequent CREATE TABLE statement. Fixing these errors should prevent the transaction from being aborted.

2. Use Proper Transaction Management: Ensure that your application is using proper transaction management techniques. If you are manually managing transactions, make sure to handle any exceptions thrown during the transaction and roll back if necessary. If you are using an ORM framework like Hibernate, make sure to configure it correctly to handle transactions.

3. Investigate Locking and Deadlock Issues: If you suspect locking or deadlock issues, use PostgreSQL's logging functionality to gather more information. Enable the log_lock_waits and deadlock_timeout parameters in your PostgreSQL configuration file to get detailed logs. Analyze these logs to identify any locking or deadlock issues and take appropriate actions to resolve them.

4. Upgrade Infinispan or PostgreSQL: If you are using an older version of Infinispan or PostgreSQL, it's worth considering upgrading to the latest stable versions. Newer versions often include bug fixes and improvements related to transaction management, which could potentially resolve your issue.
