Recensio instrumenti liberi SQLIindexManager

Ut nostis, indices magni ponderis partes in DBMS agunt, dum vivam inquisitionem ad inquisita monumenta praebes. Quam ob rem tanti momenti est illis tempestive inservire. Satis multa materia scripta est de analysi et optimiizatione, etiam in interreti. Exempli gratia, hic locus recens recensitus est hoc publication.

Multae ad hoc solvendae et liberae solutiones. Exempli gratia, promptum est решение, e methodo optimizatione indicem adaptivam fundatum.

Deinde inspiciamus de gratuita utilitate SQLIindexManager, authore AlanDenton.

Praecipua differentia technica inter SQLIindexManager et plures alias analogas ab ipso auctore datur hic и hic.

In hoc articulo, extra inspiciendum consilium et facultates operationales solutionis programmatis huius accipiemus.

De hac utilitate hic.
Subinde, cimices et commentaria plerique correcti sunt.

Itaque nunc ad SQLIindexManager utilitatem ipsam proficiscamur.

Applicatio scripta est in C#.NET Framework 4.5 in Studio Visual 2017 et utitur DevExpress pro formis:

et sic videtur:

Omnes petitiones sequentium imaginum generantur:

1. Index
2. query
3. QueryEngine
4. ServerInfo

Cum connexione cum database et quaestiones ad DBMS mittendas, applicatio haec subsignata est:

ApplicationName=”SQLIndexManager”

Cum applicationis immittas, fenestra modalis aperiet nexum adde:

Hic, plenam indicem levans omnium MS SQL Servorum instantiarum pervias per retiacula localia, nondum operatur.

Connexionem etiam addere potes utens bullam ultimi in elencho elencho:

Deinde sequentes interrogationes ad DBMS deducentur:

1. Habens informationem de DBMS

   SELECT ProductLevel  = SERVERPROPERTY('ProductLevel')

        , ServerVersion = SERVERPROPERTY('ProductVersion')
        , IsSysAdmin    = CAST(IS_SRVROLEMEMBER('sysadmin') AS BIT)
   

2. Questus index available databases cum suis brevibus proprietatibus

   SELECT DatabaseName = t.[name]
        , d.DataSize
        , DataUsedSize  = CAST(NULL AS BIGINT)
        , d.LogSize

   WHERE t.[state] = 0
       AND t.[database_id] != 2
       AND ISNULL(HAS_DBACCESS(t.[name]), 1) = 1
   

Post haec scripta exsequenda, fenestra apparebit continens breves informationes de databases instantia delectae MS SQL Server:

Notatu dignum est informationes extensas demonstrare in iuribus fundatur. Si illic sysadminErgo potes eligere notitia ex visu sys.master_files. Si talia iura non sunt, minus notitia simpliciter reddita est ut petitionem non retardet.

Hic debes eligere databases usurarum ac deprime in puga "OK".

Tabulae temporariae, ut ex ipsis quaestionibus videri potest, saepius adhibentur. Quo facto, ut nullae sint compilationes, et in magno schemate, consilium in notitia inserendo in parallelis generari potest, cum tabulae variabiles inseri nonnisi uno filo fieri possint.

Post supra scriptum exsequens, fenestra cum indice tabula apparebit;

Alias ​​accuratiores quoque informationes hic exhibere potes, ut:

1. database
2. numerus sectionum
3. diem et tempus ciemus
4. compressio
5. filegroup

and v. d.
Nativus ipsi oratores esse possunt;

In cellulis columnae Fixarum, eligere potes quae actio in optimiizatione peragatur. Item, cum scan completur, actio defalta eligitur secundum unctiones selectas;

Indices desideratos in dispensando eligere debes.

In elencho principali utens, scripto servare potes (incipit ipsum processum index optimizationis in eadem conjunctione):

et mensam in diversis formis serva (idem conjunctionem permittit ut singula loca aperias ad indices analysendos et optimizing);

Informationes quoque renovare potes strepitando in tertia puga sinistra in elencho principali iuxta vitrum magnificantem.

Bulla cum vitreo magnificando permittit ut desideratas databases ad considerationem deligeas.

Nulla in praesenti est ratio auxilii comprehensivi. Ideo premens "?" button simpliciter fenestra modalis causa est ut appareat continens informationes fundamentales de programmate producto:

Petitiones applicatio:

1. efficere ut possibilis ad selectively renovatio statistica non solum indices ac etiam diversimode (plene renovatio vel ex parte)
2. efficere posse non solum ut servientes database, sed etiam diversos ministrantes (quod percommodum est cum multae instantiae MS SQL Servo)
3. Ad maiorem flexibilitatem in usu, suggeritur involvi mandata in bibliothecis et output eas ad imperia PowerShell, ut fit, exempli gratia hic:
4. dbattools.io/mands
5. efficere posse ut occasus personales salvare et mutare tum ad totam applicationem ac, si opus sit, pro singulis instantia MS SQL Server ac singulis datorum.
6. Ex punctis 2 et 4, sequitur quod coetus a databases et coetus creare vis instantiarum MS SQL Server, quarum occasus sunt eaedem.
7. indicibus duplicatis (integri et incompleti, quae vel paulo diversae sunt vel tantum in columnis comprehensis differunt) quaeramus.
8. Cum SQLIindexManager pro MS SQL Servo DBMS tantum adhibetur, necesse est hoc nomine considerare, exempli gratia, hoc modo: SQLIindexManager pro MS SQL Server
9. Omnes GUI partes applicationis in singulos modulos non-movere et eas rescribe in .NET Core 2.1
