Rebuild and Restore Master Database in SQL Server

database - @SeniorDBA

The Master database is important to your SQL Server instance. This database records all the system-level information for your SQL Server system. This includes instance-wide metadata like logon accounts, endpoints, linked servers, system configuration settings, and records for the existence of all other databases and their file locations.

SQL Server cannot start if the Master database is unavailable. The core information of master database is recorded in a physical file called master.MDF files, and the transaction logs are stored on to the masterlog.LDF file. This means the all user and login details for the instance and the information about all the other databases on that instance are stored on the master database.

If anything happens to the master database you can’t start or use your SQL Server instance. As a Database or System Administrator, it is essential that you to know the symptoms that may indicate the corruption or damage in your Master database so you can troubleshoot those types of issues correctly.

Transaction Log File Size and VLF in SQL Server

This article by Kimberly Tripp is very interesting. Simply put, she says you want the initial size of your transaction logs set to 8 GB, with auto growth set to 8 GB. This should help keep your Virtual Lof File (VLF) sizes below 512 MB, improve performance, and make maintenance during backups much faster.

The article, in part, reads:

First, here’s how the log is divided into VLFs. Each “chunk” that is added, is divided into VLFs at the time the log growth (regardless of whether this is a manual or auto-grow addition) and it’s all dependant on the size that is ADDED not the size of the log itself. So, take a 10MB log that is extended to 50MB, here a 40MB chunk is being added. This 40MB chunk will be divided into 4 VLFs. Here’s the breakdown for chunksize:

chunks less than 64MB and up to 64MB = 4 VLFs
chunks larger than 64MB and up to 1GB = 8 VLFs
chunks larger than 1GB = 16 VLFs

Microsoft Plans Office 365 Upgrades

Office 365 - @SeniorDBA

A few months ag0 Microsoft announced that Windows 10 would receive major updates just twice a year, scheduled for September and March. Based on feedback from enterprise customers wanting a more tolerable schedule, Microsoft moved to make their release schedule more predictable.

What some people missed is that they also announced an identical schedule for corporate subscribers to Office 365. They aligned the update schedule with Windows 10. Microsoft says they plan to deliver and support Office 365 ProPlus updates, starting in September.

Microsoft also extended support 50% from 12 months per update to 18 months. The additional six months means your IT team can choose to push updates just once or twice a year.

The twice-a-year feature updates will be named Semi-annual Channel (Pilot) and Semi-annual Channel (Broad), each describing how Microsoft envisions them being deployed in the enterprise. Most people will probably just refer to them as simply “Pilot” and “Broad”.
