So far, the design is holding up and we have only one fragmentation issue to deal with. However, since database fragmentation is a major cause of poor performance I thought a discussion of how to minimize and deal with database fragmentation in SQL Server might be generally useful. ...
However, with frequent data alterations in this table over time, the issue of SQL Server index fragmentation arises. It consists of two types: Internal fragmentation: happens when data pages in SQL Server have unnecessary data storage space or capacity. The extra space emerges due to various ...
If a heap is getting the pattern of use that results in heavy fragmentation, then it probably shouldn’t be a heap in the first place. Still, if a database has heap tables and there are good reasons for keeping these as heaps, they should be maintained to avoid any performance issue an...
However, SQL Server 2008 does not address the issue with the restore operation having to almost complete before the DBA is informed that the database cannot actually be restored. In fact, this issue is unlikely to be addressed given the nature of how restore works—see theSQL Q&A column from...

Cause of the issue in our scenario Index key is a GUID data type Things to check Please make sure that index key is not a GUID. GUIDs if included in the index key causes index fragmentation in both clustered and non-clustered indexes. A GUID key causes fragmentation because of its rando...
compared to other protocols. The protocol is not without some unique challenges, however. IKEv2 is often blocked by firewalls, which can prevent connectivity. Another lesser know issue with IKEv2 is that of fragmentation. This can result in failed connectivity that can be difficult to trouble...
(theprimaryfragmentation) induces a horizontal fragmentation of another table based on the semijoin with the primary table. In this case, the primary and derived fragments with matching values for the join attributes can be stored on the same server; this improves efficiency of a join on the ...
