Dib u eegista qalabka bilaashka ah ee SQLIndexManager

Sidaad ogtahay, tusmooyinku waxay door muhiim ah ka ciyaaraan DBMS, iyagoo siinaya baaritaan degdeg ah diiwaanada loo baahan yahay. Taasi waa sababta ay muhiim u tahay in loo adeego waqti ku habboon. Wax badan ayaa laga qoray falanqaynta iyo hagaajinta, oo ay ku jiraan internetka. Tusaale ahaan, mawduucan dhawaan ayaa dib loo eegay daabacaadan.

Waxaa jira xalal badan oo lacag iyo lacag la'aan ah tan. Tusaale ahaan, waxaa jira mid diyaarsan go'aanka, oo ku salaysan habka tusmaynta la qabsiga.

Marka xigta, aan eegno adeegga bilaashka ah Maamulaha SQLIndex, waxaa qoray AlanDenton.

Farqiga ugu weyn ee farsamo ee u dhexeeya SQLIndexManager iyo tiro analoog oo kale ah waxaa bixiyay qoraaga laftiisa halkan и halkan.

Maqaalkan, waxaan ku eegi doonaa dibadda ee mashruuca iyo awoodaha hawlgelinta ee xal software this.

Ka doodista utility this halkan.
Muddo ka dib, inta badan faallooyinka iyo kutaannada waa la saxay.

Marka, aan hadda u gudubno utility SQLIndexManager laftiisa.

Codsiga wuxuu ku qoran yahay C # .NET Framework 4.5 gudaha Visual Studio 2017 wuxuuna u isticmaalaa DevExpress foomamka:

waxayna u egtahay sidan:

Dhammaan codsiyada waxaa lagu soo saaray faylasha soo socda:

1. Index
2. Su'aasha
3. Injin waydiinta
4. ServerInfo

Marka lagu xidho xogta xogta oo aad u dirayso weydiimaha DBMS, arjiga waxa loo saxeexaa sidan soo socota:

ApplicationName=”SQLIndexManager”

Markaad bilowdo arjiga, daaqad modal ah ayaa furmi doonta si loogu daro xidhiidh:

Halkan, rarista liis dhamaystiran ee dhammaan tusaalooyinka Server-ka MS SQL ee laga heli karo shabakadaha maxalliga ah wali ma shaqaynayo.

Waxa kale oo aad ku dari kartaa xidhiidh adiga oo isticmaalaya badhanka bidix ee ugu dambeeya ee liiska muhiimka ah:

Marka xigta, su'aalaha soo socda ee DBMS ayaa la bilaabi doonaa:

1. Helitaanka macluumaadka ku saabsan DBMS

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

2. Helitaanka liiska kaydka macluumaadka ee jira oo leh hantidooda kooban

   SELECT DatabaseName = t.[name]
        , d.DataSize
        , DataUsedSize  = CAST(NULL AS BIGINT)
        , d.LogSize
        , LogUsedSize   = CAST(NULL AS BIGINT)
        , RecoveryModel = t.recovery_model_desc
        , LogReuseWait  = t.log_reuse_wait_desc
   FROM sys.databases t WITH(NOLOCK)
   LEFT JOIN (
       SELECT [database_id]
            , DataSize = SUM(CASE WHEN [type] = 0 THEN CAST(size AS BIGINT) END)
            , LogSize  = SUM(CASE WHEN [type] = 1 THEN CAST(size AS BIGINT) END)
       FROM sys.master_files WITH(NOLOCK)
       GROUP BY [database_id]
   ) d ON d.[database_id] = t.[database_id]
   WHERE t.[state] = 0
       AND t.[database_id] != 2
       AND ISNULL(HAS_DBACCESS(t.[name]), 1) = 1
   

Ka dib marka la fuliyo qoraallada sare, daaqad ayaa soo bixi doonta oo ay ku jiraan macluumaad kooban oo ku saabsan kaydinta tusaalaha la doortay ee MS SQL Server:

Waxaa xusid mudan in macluumaadka la dheereeyay la muujiyo iyadoo lagu saleynayo xuquuqda. Haddii ay jiraan sysadmin, ka dibna waxaad dooran kartaa xogta aragtida sys.master_files. Haddii aysan jirin xuquuqahaas, markaas xog yar ayaa si fudud loo soo celiyaa si aysan u yarayn codsiga.

Halkan waxa aad u baahan tahay inaad doorato kaydka xogta ee xiisaha oo guji "OK" badhanka.

Marka xigta, qoraalkan soo socda ayaa loo fulin doonaa xog kasta oo la xushay si loo falanqeeyo xaaladda tusmooyinka:

Sida laga arki karo su'aalaha laftooda, miisaska ku meel gaarka ah ayaa badanaa la isticmaalaa.

Ka dib marka la fuliyo qoraalka sare, daaqad leh tusmooyin ayaa soo bixi doona:

Waxaad sidoo kale halkan ku soo bandhigi kartaa macluumaad kale oo faahfaahsan, sida:

1. database
2. tirada qaybaha
3. taariikhda iyo wakhtiga wacitaanka ugu dambeeya
4. tuujin
5. kooxda file

iyo wixii la mid ah.
Kuwa ku hadla laftooda waa la habeyn karaa:

Unugyada tiirka Fix, waxaad dooran kartaa ficilka la samayn doono inta lagu jiro hagaajinta. Sidoo kale, marka sawirku dhammeeyo, ficilka caadiga ah ayaa la doortaa iyadoo lagu salaynayo goobaha la doortay:

Waa inaad doorataa tusmooyinka la rabo si loo habeeyo.

Adigoo isticmaalaya menu-ka ugu weyn, waxaad kaydin kartaa qoraalka (badhan la mid ah ayaa bilaabaya habka kobcinta tusmada laftiisa):

oo u kaydi miiska qaabab kala duwan (badhan isku mid ah ayaa kuu oggolaanaya inaad furto dejin faahfaahsan oo falanqaynta iyo hagaajinta tusmooyinka):

Waxaad sidoo kale cusbooneysiin kartaa macluumaadka adigoo gujinaya batoonka saddexaad ee bidix ee liiska weyn ee ku xiga muraayadda weyneynta.

Marka lagu daro wax kasta oo kor lagu sharaxay, menu-ka ugu weyn wuxuu leeyahay bar goobeed:

Waxa kale oo aad arki kartaa log of falalka la qabtay xagga hoose ee daaqada:

Daaqadda goobaha faahfaahsan ee falanqaynta tusmooyinka iyo hagaajinta, waxaad habayn kartaa doorashooyin badan oo khiyaano leh:

Codsiyada codsiga:

1. suurtagal ka dhig in si xulashada ah loo cusboonaysiiyo tirokoobyada ma aha oo kaliya tusmooyinka iyo sidoo kale siyaabo kala duwan (si buuxda u cusbooneysii ama qayb ahaan)
2. suurto gal ma aha oo kaliya in la doorto database, laakiin sidoo kale servero kala duwan (tani waa mid aad u habboon marka ay jiraan xaalado badan oo MS SQL Server)
3. Dabacsanaan badan oo isticmaalka, waxaa la soo jeediyay in lagu duubo amarada maktabadaha oo loo soo saaro amarrada PowerShell, sida la sameeyo, tusaale ahaan, halkan:
4. dbatools.io/commands
5. suurtagal ka dhig in la kaydiyo oo la beddelo goobaha gaarka ah labadaba codsiga oo dhan iyo, haddii loo baahdo, tusaale kasta oo MS SQL Server iyo xog kasta
6. Laga soo bilaabo dhibcaha 2 iyo 4, waxay ku socotaa inaad rabto inaad ku abuurto kooxo by databases iyo kooxo by MS SQL Server tusaale ahaan, kuwaas oo goobaha ay isku mid yihiin.
7. raadi tusmooyin nuqul ah (dhamays ah oo aan dhamaystirnayn, kuwaas oo ama waxyar ka duwan yihiin ama ku kala duwan yihiin kaliya tiirarka lagu soo daray)
8. Maadaama SQLIndexManager loo isticmaalo kaliya MS SQL Server DBMS, waa lagama maarmaan in tan lagu muujiyo magaca, tusaale ahaan, sida soo socota: SQLIndexManager ee MS SQL Server
9. U rar dhammaan qaybaha aan ahayn GUI ee arjiga una beddelo qaybo kala duwan oo dib ugu qor .NET Core 2.1

Waqtiga qorista, shayga 6 ee rabitaanka ayaa si firfircoon loo horumarinayaa waxaana hore u jiray taageero qaab raadinta nuqullo dhammaystiran oo la mid ah:
