Stairway to the cloud

As  I’ve been involved in a few projects lately, moving Oracle databases and middleware to the (Oracle and Azure) Cloud, I thought it would be nice to share my experience and some do’s and don’ts. This post is not meant to be a highly academic and theoretical essay with a lot of architectural talk and

Should a standby database be considered in the cloud?

To answer this question for your company, the criticalness of your application and database must be clear. In a High Availability Environment, a standby-database can be part of the technical solution to ensure minimum downtime for your database.

Webinar “Oracle migration to Postgres in the Cloud”

Recently I attended a webinar “Oracle migration to Postgres in the Cloud”. It felt a bit like cheating, as I’m more an Oracle guy and my company is Oracle Platinum partner…. But very curious how easy it is to migrate (it depends…) and what hurdles to expect. The webinar (1 hour)  is on-line to watch,

Oracle disaster recovery without licensing the DR site

Recently I got a question of a customer regarding a failover configuration. They wanted to install a second server acting as a failover server, switched off until the primary experiences an outage, and they don’t want to pay licenses for it. By bringing the failover-server to life and restore the backup,  business continues on this

Oracle licenses needed while monitoring your (non-)Oracle environment with OEM

With Oracle Enterprise Manager (OEM) you are able to monitor an Oracle environment as well as a non-Oracle environment, like Microsoft’s SQL Server. You are also able to exchange notifications between Oracle Enterprise Manager and e.g. Microsoft’s SCOM. How to monitor this heterogeneous environment. What licenses do you for monitoring? And.. do you need Oracle

Licensing ODA on NUP’s and with different metrics

Maybe a slightly outdated post about NUP’s on Oracle Database Appliances. Since Oracle launched the Oracle Database Appliance HA (with two nodes) a few years ago it has become clear that from the X7-2 and further not only the Enterprise Edition is possible to use, but also the Standard Edition. But when NOT using the

expdp, ora-1555, Query Duration = 0

During a migration of a database, a remote export/import procedure (through database-link) fails intermittently. Some tables are skipped during export, with the familiair ‘ORA-0155’ error. Snapshot too old. Procedure hasn’t changed. What’s going on, besides the obvious reasons for an ORA-0155. Database version changed from 10.2.0.4 to 11.2.0.4.
