In the last post I looked at how you can do maintenance operations on the standby node when you are working in a PostgreSQL cluster protected by EDB Failover Manager. In this post I’ll look on how you can do maintenance on the primary node (better: the node where the primary instance currently runs on). This requires slightly more work…
Recently at a customer we again implemented a PostgreSQL architecture as described some time ago. When we delivered the first draft of the documentation the question popped up how to handle maintenance tasks in a failover cluster protected by EDB Failover Manager. So, here we go… The setup of my little test environment is as follows: IP Description 192.168.22.243 Current…
When you are working on Oracle you probably learned that each DDL does an implicit commit in the background. There is no way to have DDLs wrapped in a real transaction (with the exception of the “create schema” command which I blogged about a long time ago). If you take a look a the SQL:2008 standard (ISO/IEC 9075-1:2008) you can…
While doing a project at a customer we came to a point where we needed to install pl/java into Postgres Plus Advanced Server 9.5. If you follow the official documentation you will probably fail and get stuck when trying to build pl/java with maven (at least I did fail several times). Unfortunately there is not much documentation around for solving…
When it comes to designing a PostgreSQL architecture that fits your requirements there are a couple of things to think about: Do you need a HA setup? How shall backups and restores being done and how shall all of these components get monitored? Do you need vendor support for all the tools that make up the architecture? At dbi we…
The just released version of EDB Postgres Advanced Server 9.5 introduces profiles very much the same as in Oracle. Lets have a look at it. As in Oracle there is a default profile: (enterprisedb@[local]:5445) [postgres] > x Expanded display is on. (enterprisedb@[local]:5445) [postgres] > select * from edb_profile; -[ RECORD 1 ]———–+——– prfname | default prffailedloginattempts | -2 prfpasswordlocktime |…
Some days ago EnterpriseDB released EDB Postgres Advanced Server 9.5. As usual this release contains all new features that have been introduced with PostgreSQL 9.5 plus the additions that are documented in the release notes. Some time ago I blogged on how to install the 9.4 release. In this post I want to check if anything changed in the installation…
In the last posts (1, 2, 3, 4, 5) I looked at PostgreSQL in Amazon RDS. Another option you have if you want to go to the cloud is to use the The Postgres Plus® Cloud Database offered by EnterpriseDB. I will not go through the whole setup here as this is described in detail here. So once you went…
As I could not find any information about this error when I faced it this is just a short hint: If you try to use pg_dump or pg_dumpall out of a PPAS installation to dump or dumpall a community version of PostgreSQL you probably get this: pg_dump: [archiver (db)] query failed: ERROR: schema “sys” does not exist pg_dump: [archiver (db)]…
This post takes a look on how to migrate the Oracle 12cR1 sample schemas to PPAS 9.4 (PostgreSQL Plus Advanced Server 9.4). I’ll not dig into how to install PPAS as this was described in detail some time ago. Just follow this post if you need a setup guide. If you wonder why I am doing this there are two…
Dans mon dernier article sur PostgreSQL, j’ai présenté l’installation du logiciel en explorant les 2 solutions suivantes, l’installation Debian et l’installation EntrepriseDB. Ces deux installations créent immédiatement un cluster de base de données, Debian nous imposant le point de stockage et EntrepriseDB nous proposant de saisir une destination. Je vous propose maintenant d’explorer ce qui a été installé sur votre

Dans mon précédent article concernant PostgreSQL, j’ai annoncé une serie d’article sur ce SGBDR, aprés une courte introduction et avant de plonger dans le fonctionnement interne, l’architecture etc… je vous propose d’aborder l’installation du produit.
