    Before learning to eliminate fragmentation, you should have a clear understanding of the types of fragmentation. We can classify fragmentation into two types:

    Internal Fragmentation: When records are stored non-contiguously inside the page, then it is called internal fragmentation. In other words, internal fragmentation is said to occur if there is unused space between records in a page. This fragmentation occurs through the process of data modifications (INSERT, UPDATE, and DELETE statements) that are made against the table and therefore, to the indexes defined on the table. As these modifications are not equally distributed among the rows of the table and indexes, the fullness of each page can vary over time. This unused space causes poor cache utilization and more I/O, which ultimately leads to poor query performance.

    External Fragmentation: When on disk, the physical storage of pages and extents is not contiguous. When the extents of a table are not physically stored contiguously on disk, switching from one extent to another causes higher disk rotations, and this is called Extent Fragmentation.

    murag naa na belong sa internal fragmentation sir, diba murag sa non-clustered index? ky mag create man ug pages.. naka kita ko ug script to view the fragmentation percentage ang number of pages base sa result ky tag 99 percent nya almost 15k pages nya ang mga rows 1M plus..

    Sir @defender_1611, i really hope matabangan ko nimo sa akong problema ba...
    Ambot kung pareha ba mi ni @nyor... basta beginners ra sad ko...
    Scenario sir sa akong clustering nga mo.work pero naay problema:
    naa koy db1, db2, witness server and 2 ka subscribers...
    kung mo.down ang db1, automatic failover sya sa db2 ky nka.mirror man.

    Question nako sir:
    1. nganu kung e.view nko ang synchronization status sa db2 ky running sya nya sa subscribers ky error man sya?, pero ang data ky okay ra replicate ra gyapon nya ang mga subscribers sa db1 ky automatic balhin ra sa db2. pero mao lage error ang view synchronization status kung sa subscriber ko mag.view... dili nko ma.monitor.

    2. naa bay way sir nga ma.backup.pan nako ang akong witness kung sya na sd ang mo.down?, (na.test nako nga kung y witness dli mg.synchronize ang mga data.)

    configuration info:
    push configuration akong gamit sa subscriber.

    Hope sir nga imo kung matabangan...

    up nato ni nga thread....

    Sir @defender_1611 , unsa imong ma.advise ani akong problem?
