Infrastructure at your Service
Today, many enterprises are striving to transform their IT organization from a cost center into a strategic asset and looking for ways to get more value from their application and data platform investments. To deliver on this vision, Microsoft SQL Server 2016 – via its on-premises, cloud, or hybrid deployment options – provides customers with significantly lower total cost of ownership (TCO) compared to existing Oracle DB platform. How to know the real difference in…
Qu’est-ce que DBSAT ? C’est un outil gratuit d’Oracle que vous pouvez télécharger sur My Oracle Support avec comme référence : Doc Id 2138254.1. Il a pour but d’évaluer la sécurité de vos bases de données Oracle en analysant la configuration et les stratégies de sécurité mise en place afin de découvrir les risques liés à la sécurité. Comment cela fonctionne t-il ? Dans un premier temps il sera nécessaire de collecter les informations de…
When it comes to choose a cloud instance to run Oracle Database, you want to be able to run your workload on the minimum CPU cores. This is why in a previous post I measured how many logical reads per seconds can be achieved with a SLOB workload, on AWS which is often the first considered, and will probably do it on Azure in the future. I did the same on the Oracle Cloud which…
In the Oracle Public Cloud, fast provisioning gets all its meaning when creating a RAC database service: in one hour you can get an operational highly available multitenant database. You can even create it in Data Guard for Disaster Recovery. Now, Oracle is pushing ACFS to store the datafiles rather than direct ASM. Especially in multitenant because a great feature is thin cloning: CREATE PLUGGABLE DATABASE AS SNAPSHOT COPY. However, I encountered an error when…
If you use a login.sql script to set the SQL*Plus environment from your current working directory, you will see that it will not run anymore in 12.2. This is a security feature, and a good occasion to explain how sqlplus finds the scripts to run, on Linux.
In the latest post I’ve run a cached SLOB workload on Oracle Cloud IaaS to measure logical reads per seconds on a system covered by 2 processor licences (so 4 OCPs). Just as a comparison, here is the same on Oracle PaaS database as a service.
The Oracle PDBaaS is for database developers. And database developers may need to trace what happens with their queries: SQL trace and Optimizer trace. Let’s see what we can do on Exadata Express Cloud Service
In Oracle Public Cloud, Transparent Data Encryption is not an option. You can use it because it is included in all database services for all editions. You have to use it because the database won’t allow you to create, or import, non encrypted tablespaces. This is controlled by a new parameter, encrypt_new_tablespaces, which defaults to CLOUD_ONLY;
The separation of roles between system DBA and application DBA is the way to go for agile development and the PDBaaS managed service is an excellent way to play with this concept: You are PDB administrator but not the CDB administrator. Here is an example about tablespace creation/deletion, and the kind of problems that may arise with this architecture.
In a previous blog we installed Dbvisit Standby 7 on two AWS linux instances. In this article we are just upgrading to Dbvisit Standby 8. The first thing is to stop on both nodes dbvnet and dbvserver on both servers [oracle@primaserver dbvnet]$ ps -ef|grep dbv|grep -v grep oracle 2062 1 0 04:53 ? 00:00:02 /u01/app/dbvisit/dbvserver/dbvserverd oracle 2064 2062 0 04:53 ? 00:00:00 /u01/app/dbvisit/dbvserver/dbvserverd oracle 2131 1 0 04:54 ? 00:00:00 /u01/app/dbvisit/dbvnet/dbvnetd oracle 2132 2131 0…
