Are you preparing for IBM – MVS job interview?. MVS is Multiple Virtual Storage was one of the operating system commonly used on System/370 and 390 IBM computers. MVS supports very large virtual storage that is larger than available storage. MVS is the perfect solution for business problems that resulted from the need to run more applications. Job Control Language is the main user interface to MVS. Later on CICS and TSO, the interactive time sharing interface are used mainly to run development tools. TSOs basic interface is command line. MVS software recovery is used for problem debugging. Good knowledge on these concepts will fetch right job. Wisdomjobs framed IBM – MVS job interview questions and answers to make it easier for your interview preparation.

SQL Server 2012 AlwaysOn Availability Group supports row and page compression for tables and indexes, we can use the data compression feature to help compress the data inside a database, and to help reduce the size of the database. We can use encryption in SQL Server for connections, data, and stored procedures; we can also perform database level encryption: Transparent data encryption (TDE). If you use transparent data encryption (TDE), the service master key for creating and decrypting other keys must be the same on every server instance that hosts an availability replica for the availability group
The faster your network and your servers are, and the less transactional activity you have, the more up-to-date each replica will be. I’ve seen setups where the replicas are indistinguishable from the primary. However, I’ve also seen cases with underpowered replicas, slow wide area network connections, and heavy log activity (like index maintenance) where the replicas were several minutes behind.
SQL Server 2014’s biggest improvement is that the replica’s databases stay visible when the primary drops offline – as long as the underlying cluster is still up and running. If I have one primary and four secondary replicas, and I lose just my primary, the secondaries are still online servicing read-only queries. (Now, you may have difficulties connecting to them unless you’re using the secondary’s name, but that’s another story.) Back in SQL 2012, when the primary dropped offline, all of the secondaries’ copies immediately dropped offline – breaking all read-only reporting queries.
Session-timeout period is a replica property that controls how many seconds (in seconds) that an availability replica waits for a ping response from a connected replica before considering the connection to have failed. By default, a replica waits 10 seconds for a ping response. This replica property applies only the connection between a given secondary replica and the primary replica of the availability group.
When I go through an AG design with a team, we talk about the work required to merge the two databases together. If it’s complex (like lots of parent/child tables with identity fields, and no update datestamp field on the tables), then management agrees to a certain amount of data loss upon failover. For example, “If we’re under fifteen minutes of data is involved, we’re just going to walk away from it.” Then we build a project plan for what it would take to actually recover >15 minutes of data, and management decides whether they want to build that tool ahead of time, or wait until disaster strikes.
Difference between TSO and ISPF
| TSO | ISPF |
| Stands for Time Sharing Option | Stands for Interactive system productivity facility |
| Used to create an interactive session | You can add, configure and manage the system using ISPF |
| TSO allows users to access ISPF | ISPF is Menu driven |
