blockchain is a decentralized technology that acts a digital open distributed ledger and is used to record transaction data between two parties that is both verifiable and permanent. Made famous, or infamous, by Bitcoin, this article will separate the entities and focus on the technology behind blockchain, and its potential application. Blockchains are composed of a block, a timestamp and the transaction data, as well as a cryptographic hash of the previous block that links the two by cryptography. A single blockchain exists within a network of computers and cannot be edited without changing all other blocks - by design, making them permanent and resistant to change. As such, participants can track, control, and verify transactions efficiently and securely. A good example is to picture a blockchain as a giant spreadsheet that has been shared hundreds of times across a network of computers that exist solely to update the spreadsheet regularly.

The Problem:

SharePoint is, of course, a monster of an application platform with many configuration quirks.  As a DBA supporting a content database utilized by a SharePoint environment, I ran across a problem:  After installing SharePoint, there is no way for the application administrator to tell the DBA the real database name. 

The Reason: 

During installation, an alias is created for the database.  Unless you write that name down or name the alias something that reflects the database name, there is no clear way to determine the name of the database, either in the application or in the configuration files.

The Solution:

Since the solution was not particularly obvious, I’d like to share it, so that another DBA does not have to solve the issue at the worst possible time:  an outage.

Your DBA is receiving complaints about a slow server at random periods throughout the week.  How do you assess the environment and troubleshoot performance issues at different periods?

Using a series of PowerShell scripts, you can easily gather key statistics across your entire environment, and run the process several times a day to capture those statistics during different time periods and activity levels.  The data is stored in a series of tables, which can then be used for alerting and trend reporting.
