Marcin Policht provides an overview of a number of new features that facilitate Azure SQL Database business continuity.
When you are setting up a new SQL Server machine you need to determine how big you should make tempdb. To make sure you size tempdb appropriately you should monitor the tempdb space usage. If there are autogrowth events occurring after you have recycled SQL Server than you might want to increase the size of your tempdb data files. If tempdb never uses most of the tempdb space, then you might want to consider decreasing the size of tempdb.
There may be a time when you want to turn off transparent data encryption on one of your TDE enabled databases. In this tip, Greg Larsen shows you how simple it is to remove Transparent Data Encryption.
Keeping data secure also means keeping it obscured should a breach occur. Read on to see how Oracle's Transparent Data Encryption can keep that data from prying eyes.
The cursor_sharing=force setting is designed to substitute system-generated bind variables for literals, but there are cases where not all literals are replaced. Read on to see when this can occur.
Many organizations are looking at the prospect of a technology migration, where capabilities are moved to a new set of technologies, supporting and enabling the business of the future. Anoop Kumar lays out the steps that can be followed to migrate an on-premise Oracle database to the SQL Server cloud database, Azure SQL Database.
IBM’s Db2 Version 12 for z/OS was designed to synergize with new IBM z14 hardware, which includes several new and updated options for hardware-assisted data encryption and compression. These features can be used by the database management system to store and retrieve encrypted and compressed data transparently without application knowledge or intervention. Read on to learn more.
IBM now provides an option to configure its Db2 version 12 for z/OS and complementary IBM Db2 Analytics Accelerator (IDAA) to permit concurrent transactional processing of operational data with analytics processing of data in the appliance. This new feature, zero-latency HTAP (hybrid transactional analytical processing) provides a patented replication process that propagates native Db2 table changes to the IDAA data store. This then allows BI queries to act on up-to-date data.
The General Data Protection Regulation (GDPR) went into effect worldwide on May 25, 2018. In response, companies throughout the world increased their data security awareness, appointed data protection officers and updated their privacy policies. IT support staff responded with updated data dictionaries, flagging of personal data, encryption at various points (local and cloud storage, network traffic, etc.) and heightened security procedures. However, more work is needed. In this article we focus on what the DBA must do in the near term in order to anticipate and prevent performance and capacity issues.
