EDB Failover Manager in EDB containers in Minishift/OpenShift – Failovers

By | Database Administration & Monitoring | No Comments

In the last post we had a look at the basic configuration of EDB EFM and confirmed that we can do manual switchovers for maintenance operations. Being able to do a switchover and switchback is fine but what really is important are automatic failovers. Without an automatic failover this setup would be somehow useless as a) EDB EFM is supposed to do exactly that and b) without that we would need to implement something on…

OpenSSH is now available on Windows 10

By | Database Administration & Monitoring | No Comments

A couple of days ago, the Windows 10 april 2018 update was installed on my laptop. And what, you may say? Well, surprisingly this update provides some interesting “hidden” features and one of them concerns OpenSSH that is now available on-demand in Windows 10 (and likely available soon on Windows Server). This a obviously a good news because so far, I used either putty or directly a bash environment from my Windows 10 laptop available since…

Windocks – a different way to use SQL Server on Docker

By | Database Administration & Monitoring | No Comments

I spent some times to write blog posts about SQL Server on Docker since few months and you likely noticed it concerned mainly SQL Server on Linux. But what about SQL Server on Docker and Windows? If you take a look at the Docker images provided by Microsoft, only 2017 version is available and it is only intended for development and testing use. Versions prior 2017 seem to not be supported so far (but I…

Scaling the EDB containers in MiniShift/OpenShift

By | Database Administration & Monitoring | No Comments

When you followed the last post you should have two pgpool instances and one EDB Postgres instance running in OpenShift. pgpool is responsible for the load balancing, meaning: Send write requests to the master instance and spread read requests over all instances. In the current setup this does not make much sense as we only have one instance so in this post we will scale the setup to finally consist of one master and one…

PDB RMAN backups available after plugging in on a new CDB with Oracle 18c

By | Database Administration & Monitoring | No Comments

With Oracle 18c, it is possible to use PDB rman backups created on the source CDB (they are called PREPLUGIN backups) when the PDB has been relocated to a target CDB. In my environment, my original CDB is DB18, with the PDB named pdborig. The target CDB is PSI18. The first step consist in running a rman backup on pdborig: oracle@localhost:/u00/app/oracle/ [DB18] rman target sys/manager@pdborig Recovery Manager: Release 18.0.0.0.0 – Production on Tue May 15…

SP2 for SQL Server 2016 is available with new helpful DMVs

By | Database Administration & Monitoring, Development & Performance, SQL Server, Technology Survey | No Comments

Last month (April 24, 2018), the Service Pack 2 for SQL Server 2016 was released and distributed. This Service Pack has new DMVs, already available in SQL Server 2017 RTM. In this article, I will just write few words about 2 DMVs (sys.dm_db_log_stats & sys.dm_db_log_info) and a new column (modified_extent_page_count) in the DMV sys.dm_db_file_space_usage that I presented during our last event about SQL Server 2017. I think they are really helpful for DBA. It’s also…
