Feed: Planet MySQL; Author: Marcelo Altmann; Chasing bugs can be a tedious task, and multi-threaded software doesn’t make it any easier. Threads will be scheduled at different times, instructions will not have deterministic results, and in order for one to reproduce a particular issue, it might require the exact same threads, doing the exact same work, at the exact same time. As you can imagine, this is not straightforward. Let’s say your database is crashing or even having a transient stall.  By the time you get to it, the crash has happened and you are stuck restoring service quickly and ... Read More

Feed: Planet PostgreSQL. A reliable backup tool with an ability to perform a point in time recovery (PITR) is a usual enterprise need. Postgres includes a backup tool called pg_basebackup for full backups. It is great for a database of a few hundreds of GBs in size but currently lacks the support for parallel, incremental and differential backups. This makes it slightly challenging for bigger postgres databases that are Terrabytes in size. pgBackRest is our savior in such a case. While migrating from Oracle to Postgres, users find pgBackRest as an Oracle RMAN equivalent for PostgreSQL with some more additional ... Read More

Feed: Planet PostgreSQL. The pgBackRest team is pleased to announce the introduction of multiple repository support in v2.33.

This feature is the culmination of many months of hard work, so let's delve into why we think multiple repositories are so important and how they can help preserve your data ... Read More

Feed: Planet MySQL; Author: MySQL Performance Blog; So your MySQL server has crashed.  What do you do now?  When a server is down, in my opinion, there are two steps that are essential and both are extremely important and neither should be neglected: Save diagnostic information for determining the root cause analysis (RCA). Get the server back up and running. Too many people rush to Step #2 and lose pertinent diagnostics from Step #1.  Likewise, too many people will spend too much time on Step #1 and delay getting to Step #2 and restoring service.  The goal is to collect ...
