Infrastructure at your Service
Introduction RDS provide automatic backup feature. This feature will backup the entire RDS instance. As a DBA sometimes you need to backup individual database, they are many reason for that (legal, migration, replication,…). Unfortunately individual database backups are not available within the RDS instance. This post explains how you can enable the native database backup on RDS , as you are used to with an on-premises SQL Server instance. To summarize we will create a…
The SQL Server environment I worked with today has dozens of SQL Server instances using AlwaysOn Availability Groups for High Availability. When a login is created on the Primary replica of an Availability Group it is not synchronized automatically on secondary replicas. This might cause some issues after a failover (Failed logins). Since this is not done automatically by SQL Server out of the box the DBA has to perform this task. To avoid doing…
What is Nagios ? “Nagios is a powerful monitoring system that enables organizations to identify and resolve IT infrastructure problems before they affect critical business processes.” https://www.nagios.org/ In simple words, you can monitor your servers (linux, MSSSQL, etc …) and databases (Oracle, SQL Server, Postgres, MySQL, MariaDB, etc …) with nagios. We use the free version !!! 😀 VM configuration : OS : CentOS Linux 7 CPU : Intel(R) Xeon(R) CPU E5-2620 v4…
During my last blog post I explained how to installed a MABS. Now that your infrastructure is setup you will be able to protect the workload of your Hyper-V Virtual Machines. You have first to create a new protection group. This group will contain one or more VMs which will share the same backup configuration for retention, synchronization and recovery. Protection is managed as follow: DPM create a copy of the selected data on the…
By one of our customer we use Avamar for the backup and restore solution. I was asked by this customer to find a solution to run Avamar backups for a group of databases on a specified instance. In fact, we currently try a database clone solution on some instances and clone’s databases must not be backed up, but the rest of the databases must be. After some discussions with my colleague I decided to use…
I just had to restore a database in production for my customer. Before doing the restore I have the habit to query the msdb.dbo.backupset table to get an overview of the last backups. When running my query, I felt it was taking longer than usual. So out of curiosity, I looked at the SSMS standard report “Disk Usage by Top Tables”. Here is the output. This instance contains dozens of databases in Always On Availability…
MSSQL-CLI is a useful new command line tool. Not so new because this tool exist since 2018 but a little bit unknow. You find this tool on GitHub here. One of the big advantage is the number of platforms available, Windows of course but also macOS, Ubuntu, Debian, CentOs, Red Hat, OpenSuse, Suse Enterprise and Fedora. This interactive command-line query tool has many advantages like the full IntelliSense support, the auto-complete, the syntax highlighting, the…
AWS S3 offers different Storage Classes, allowing to optimize cost among others. For instance, some classes are used for archiving purposes: S3 Glacier and S3 Glacier Deep Archive. It means the storage cost is the lowest you can obtain, but your data is not available immediately and the access cost is increased. In the case of S3 archive classes, retrieving the data is not cost-effective because this is clearly not what it is aimed for….
By Franck Pachot The Oracle Cloud is not only for Oracle Database. You can create a VM running Oracle Linux with full root access to it, even in the free tier: a free VM that will be always up, never expires, with full ssh connectivity to a sudoer user, where you are able to tunnel any port. Of course, there are some limits that I’ve detailed in a previous post. But that is sufficient to…
In addition of my precedent blog about this subject “SQL Server Tips: Default trace enabled but no file is active…”, I add a new case where the default path of the trace file was empty. The first step was to verify if the default trace is enabled with the command: SELECT * FROM sys.configurations WHERE name=’default trace enable’ It is enabled, then I check the current running trace with the view sys.traces SELECT * FROM…
