TimescaleDB

Upgrading your PostgreSQL 11 to PostgreSQL 13 with TimescaleDB and PostGIS can be a tedious job, especially if you’re not familiar with the steps and procedures. What are the caveats and the prerequisites for doing this before you start the job? This blog will guide you on how to manage the major version upgrade on a complex setup with plugin extensions being enabled such as TimescaleDB and PostGIS.

Data is probably the most valuable asset in a company, so you need to make sure it is safe and can be restored in case of failure. In this blog, we will see how to restore a PostgreSQL and TimescaleDB backup from the ClusterControl CLI using the powerful s9s tool.

Backups are a basic step in all Disaster Recovery Plans, but the management and monitoring of them could be a difficult task if you have a complex environment. In this blog, we will see how you can use ClusterControl to manage your PostgreSQL backups using advanced backup features.

When you install ClusterControl, it has a default configuration that maybe doesn’t fit your requirements, so probably you will need to customize this installation. In this blog, we will show you where you can modify the configuration and the available options.

Security is a must for all systems. Even when there is always a risk to be hacked, by following a security checklist will reduce this risk significantly. As part of this security checklist, on Debian-Based operating systems you can use a tool called AppArmor to help you in this task. In this blog, we will see what is and how to configure it for PostgreSQL and TimescaleDB databases.

To protect your data it is important to take all the security considerations into account in your database servers. One important security feature on RedHat-based Operating Systems is SELinux. In this blog, we will see what this feature is and a basic configuration to make it work for PostgreSQL and TimescaleDB databases.

Advanced failover is very important - it might even be necessary when you have a very complex database setup. When dealing with disasters that can happen in unanticipated events, pre/post scripts can be very helpful to determine how feasible and how true is the alarm that was triggered. Proceeding on a failover after a false positive is a waste of money, resources, and waste of time. ClusterControl has these features and this blog demonstrates how you can take advantage of them dedicated for advanced failover.

ClusterControl offers you a different approach of managing databases which can not be observed and experienced in other platforms. It can be deployed on-prem, on the cloud, or on a containerized type of environment. It can be deployed flexibly and has a massive feature that offers rich and powerful operations that makes it easier to manage your database and without requiring you to create your automated scripts. ClusterControl will handle this for you as shown by this blog. This blog showcases how it is feasible to manage multiple database technologies with ClusterControl.

Data governance defines a set of principles to ensure data quality in a company. It describes the processes, roles, policies or responsibilities, and metrics to ensure accountability and ownership of data assets across the enterprise. This blog discusses the six critical components to successful data governance for better data quality.

In this blog post, we are going to focus on SNMP traps and alerting. SNMP Traps are the most frequently used alert messages sent from a remote SNMP-enabled device (an agent) to a central collector, the “SNMP manager.” In the case of ClusterControl, a trap could be an alert after the critical alarm for a cluster is not 0, indicating something bad is happening.

In this blog series, we are going to showcase a proof-of-concept (PoC) on how to integrate ClusterControl with SNMP protocol. At the end of the blog series, we would ultimately be able to send an SNMP trap to an SNMP manager (Nagios, Zabbix, etc). In this first part, we are going to cover the MIB and SNMP agent.

Managing a very large database incurs huge challenges and fears in case of data loss, disasters, or lack of experience of the database to use. However, knowing the basics that could help you determine beforehand to prepare things and make it efficient is the most important thing to have. This blog covers these things on how to manage a very large database and what are the things you have to know.

In this blog post, we are going to look into the new user management system introduced in ClusterControl 1.8.2, and to see how it is different from the previous ones. Just for clarification, the old user management system will still work side-by-side with the new user authentication and management system until Q1 2022. From now on, all new installations for ClusterControl 1.8.2 and later will be configured with the new user management system.

Configuration check and tuning are an important part of the DBA and SysAdmin routine to ensure a critical system like database and reverse proxies are always relevant and optimal as your workloads grow. Our focus in this blog post is to automate the database configuration check and validation process.

This blog provides a brief guide on how to start with database automation. It will walk you through the main points and essentials of database automation, such as what can be and what should not be automated, and discusses some useful automation tools.

Role-Based Access Control (RBAC) in ClusterControl allows super administrators to provide fine-grained restrictive access based on a role.  This blog guides you in using RBAC, teaching you the differences among available roles and how to use roles and their privileges to achieve a desired level of security.

Hybrid Cloud vs Full Public Cloud dares how organizations and companies have to decide and design the infrastructure to achieve high availability, scalability but with tightened security. In this blog, we showcase how both differ and how you are going to utilize them whenever you engage with these infrastructure solutions for your business requirements.

Object storage in the cloud is inexpensive, reliable and durable, and is a great way of archiving backup data. In this blog, we will share some tips on how to store TimescaleDB backups on AWS S3 and Google Cloud Storage.

If you need to handle time-series data in your current PostgreSQL installation, you should consider enabling TimescaleDB there to manage it in a more performant way. In this blog, we will see how to enable TimescaleDB in an existing PostgreSQL installation both manually and using ClusterControl.

In this blog post, we look deeper into one of the most advanced features offered by ClusterControl called automatic database recovery and failover. ClusterControl is able to recover clusters, nodes and database-related processes to ensure you achieve the best database uptime possible.

PostgreSQL and its underlying platform solutions can help you cut down the high costs associated with an Oracle Database license; all with small to moderate changes. This blog walks you through some of the advantages of migrating from Oracle to PostgreSQL for your SQL database needs.
