Allen Cao, Niyaz Mohamed, NetApp
Scopo
Il ripristino di un database molto grande (VLDB) in Oracle utilizzando lo strumento di backup di Oracle Recovery Manager (RMAN) può essere un'attività molto complessa. Il processo di ripristino del database dai supporti di backup in caso di errore può richiedere molto tempo, ritardando il ripristino del database e potenzialmente compromettendo significativamente il contratto SLA (Service Level Agreement). Tuttavia, a partire dalla versione 10g, Oracle ha introdotto una funzionalità RMAN che consente agli utenti di creare copie di immagini a fasi dei file di dati del database Oracle su un ulteriore storage su disco situato sull'host del server DB. Queste copie delle immagini possono essere aggiornate in modo incrementale utilizzando RMAN ogni giorno. In caso di guasto, l'amministratore del database (DBA) può passare rapidamente dal supporto guasto alla copia dell'immagine del database Oracle, eliminando la necessità di un ripristino completo dei supporti del database. Il risultato è un SLA notevolmente migliorato, anche se al costo di raddoppiare lo storage del database richiesto.
Se sei interessato a SLA per VLDB e desideri spostare il database Oracle in un cloud pubblico come AWS, puoi impostare una struttura di protezione del database simile utilizzando risorse come AWS FSX ONTAP per gestire la copia dell'immagine del database in standby. In questa documentazione, dimostreremo come eseguire il provisioning e l'esportazione di un file system NFS da AWS FSX ONTAP per il montaggio su un server di database Oracle per lo staging di una copia di database in standby per un ripristino rapido in caso di guasto dello storage primario.
Inoltre, mostreremo come sfruttare NetApp FlexClone per creare una copia dello stesso file system NFS di staging per altri casi di utilizzo, come ad esempio la creazione di un ambiente Oracle di sviluppo/test con la stessa copia dell'immagine di database di standby senza ulteriori investimenti in storage.
Questa soluzione risolve i seguenti casi di utilizzo:
-
Un'Unione incrementale della copia dell'immagine Oracle VLDB tramite RMAN sul punto di montaggio NFS dallo storage AWS FSX ONTAP.
-
Ripristino rapido di un VLDB Oracle passando alla copia dell'immagine del database sullo storage FSX ONTAP in caso di guasto.
-
Clonare il volume del file system NFS di FSX ONTAP che memorizza una copia dell'immagine Oracle VLDB da utilizzare per creare un'altra istanza di database per altri casi di utilizzo.
Pubblico
Questa soluzione è destinata alle seguenti persone:
-
Un DBA che ha configurato la fusione incrementale delle copie delle immagini di Oracle VLDB tramite RMAN in AWS per un ripristino più rapido del database.
-
Un architetto di soluzioni di database che testa i carichi di lavoro Oracle nel cloud pubblico AWS.
-
Amministratore dello storage che gestisce i database Oracle implementati nello storage AWS FSX ONTAP.
-
Proprietario di un'applicazione che desidera supportare i database Oracle in un ambiente AWS FSX/EC2.
Ambiente di test e convalida della soluzione
Il test e la convalida di questa soluzione sono stati eseguiti in un ambiente AWS FSX ONTAP ed EC2 che potrebbe non corrispondere all'ambiente di implementazione finale. Per ulteriori informazioni, vedere la sezione [Key Factors for Deployment Consideration].

Fattori chiave per l'implementazione
-
Layout dello storage Oracle VLDB per la fusione incrementale RMAN. nei nostri test e convalide, il volume NFS per il backup incrementale e la fusione Oracle viene allocato da un singolo file system FSX, con throughput di 4 Gbps, 160,000 IOPS SSD raw e limite di capacità di 192 TiB. Per l'implementazione oltre le soglie, è possibile concatenare più file system FSX in parallelo con più punti di montaggio NFS per fornire una capacità superiore.
-
Ripristinabilità di Oracle con la fusione incrementale di RMAN. il backup incrementale e l'Unione di RMAN vengono generalmente eseguiti a una frequenza definita dall'utente in base agli obiettivi RTO e RPO. In caso di perdita totale dello storage primario e/o dei registri archiviati, si può verificare la perdita dei dati. Il database Oracle può essere ripristinato fino all'ultimo backup incrementale disponibile dalla copia dell'immagine di backup del database FSX. Per ridurre al minimo la perdita di dati, è possibile configurare l'area di ripristino flash Oracle sul punto di montaggio NFS FSX e eseguire il backup dei registri archiviati sul montaggio NFS FSX insieme alla copia dell'immagine del database.
-
* Esecuzione di Oracle VLDB dal file system NFS FSX.* a differenza di altri sistemi di storage in blocco per il backup del database, AWS FSX ONTAP è uno storage di livello produzione abilitato al cloud che offre un elevato livello di performance ed efficienza dello storage. Una volta che Oracle VLDB passa dallo storage primario alla copia dell'immagine sul file system NFS FSX ONTAP, le performance del database possono essere mantenute ad alto livello mentre viene risolto il guasto dello storage primario. Puoi stare tranquillo nel sapere che l'esperienza dell'applicazione utente non subisce alcun problema a causa di un guasto dello storage primario.
-
FlexClone copia dell'immagine Oracle VLDB del volume NFS per altri casi di utilizzo. AWS FSX ONTAP FlexClone fornisce copie condivise dello stesso volume di dati NFS scrivibili. Pertanto, possono essere utilizzati per molti altri casi di utilizzo, mantenendo l'integrità della copia dell'immagine Oracle VLDB in fase di staging anche quando il database Oracle viene commutato. In questo modo si ottiene un notevole risparmio sui costi di storage riducendo sostanzialmente l'impatto dello storage VLDB. NetApp consiglia di ridurre al minimo le attività di FlexClone in caso di passaggio da uno storage primario a una copia dell'immagine del database per mantenere le performance di Oracle ad alto livello.
-
Istanze di calcolo EC2. in questi test e convalide, abbiamo utilizzato un'istanza AWS EC2 t2.xlarge come istanza di calcolo del database Oracle. NetApp consiglia di utilizzare un'istanza EC2 di tipo M5 come istanza di calcolo per Oracle nell'implementazione in produzione, poiché è ottimizzata per il carico di lavoro del database. È necessario dimensionare l'istanza EC2 in modo appropriato in base al numero di vCPU e alla quantità di RAM in base ai requisiti effettivi del carico di lavoro.
-
Implementazione di cluster ha storage FSX a singola o multi-zona. in questi test e convalide, abbiamo implementato un cluster ha FSX in una singola zona di disponibilità AWS. Per l'implementazione in produzione, NetApp consiglia di implementare una coppia FSX ha in due diverse zone di disponibilità. Un cluster FSX ha viene fornito in maniera ininterrotta in una coppia ha con mirroring sincronizzato in una coppia di file system Active-passive per fornire ridondanza a livello di storage. L'implementazione multi-zona migliora ulteriormente l'alta disponibilità in caso di guasto in una singola zona AWS.
-
Dimensionamento del cluster di storage FSX. un file system di storage Amazon FSX per ONTAP fornisce fino a 160,000 IOPS SSD raw, throughput fino a 4 Gbps e una capacità massima di 192 TiB. Tuttavia, è possibile dimensionare il cluster in termini di IOPS con provisioning, throughput e limite di storage (minimo 1,024 GiB) in base ai requisiti effettivi al momento dell'implementazione. La capacità può essere regolata dinamicamente in tempo reale senza influire sulla disponibilità delle applicazioni.
-
Configurazione DNFS. DNFS è integrato nel kernel Oracle e, quando Oracle viene distribuito sullo storage NFS, aumenta notevolmente le performance del database Oracle. DNFS viene inserito in un pacchetto binario Oracle, ma non viene attivato per impostazione predefinita. Deve essere attivato per qualsiasi implementazione di database Oracle su NFS. Per l'implementazione di più file system FSX per un VLDB, è necessario configurare correttamente il percorso multiplo DNFS per diversi file system NFS FSX.
Implementazione della soluzione
Si presuppone che il proprio Oracle VLDB sia già stato implementato in un ambiente AWS EC2 all'interno di un VPC. Per assistenza sull'implementazione di Oracle in AWS, consulta i seguenti report tecnici.
Il tuo Oracle VLDB può essere eseguito su un FSX ONTAP o su qualsiasi altro storage disponibile nell'ecosistema AWS EC2. La sezione seguente fornisce le procedure di implementazione passo-passo per impostare la fusione incrementale di RMAN su una copia immagine di un database virtuale Oracle in fase di staging in un montaggio NFS dallo storage ONTAP di AWS FSX.
Prerequisiti per l'implementazione
Details
L'implementazione richiede i seguenti prerequisiti.
-
È stato impostato un account AWS e sono stati creati i segmenti VPC e di rete necessari all'interno dell'account AWS.
-
Dalla console AWS EC2, è necessario implementare due istanze EC2 Linux, una come server Oracle DB primario e un server DB di destinazione clone alternativo opzionale. Per ulteriori informazioni sulla configurazione dell'ambiente, vedere il diagramma dell'architettura nella sezione precedente. Esaminare anche il "Guida utente per istanze Linux" per ulteriori informazioni.
-
Dalla console AWS EC2, implementare Amazon FSX per cluster ha di storage ONTAP per ospitare i volumi NFS che memorizzano la copia dell'immagine di standby del database Oracle. Se non si ha familiarità con l'implementazione dello storage FSX, consultare la documentazione "Creazione di FSX per file system ONTAP" per istruzioni dettagliate.
-
I passaggi 2 e 3 possono essere eseguiti utilizzando il seguente toolkit di automazione Terraform, che crea un'istanza EC2 denominata
ora_01E un file system FSX denominatofsx_01. Prima dell'esecuzione, rivedere attentamente le istruzioni e modificare le variabili in base all'ambiente in uso. Il modello può essere facilmente rivisto in base ai tuoi requisiti di implementazione.git clone https://github.com/NetApp-Automation/na_aws_fsx_ec2_deploy.git
|
Assicurarsi di aver allocato almeno 50 G nel volume root dell'istanza EC2 per avere spazio sufficiente per la fase dei file di installazione Oracle. |
Provisioning ed esportazione del volume NFS da montare sull'host dell'istanza DB EC2
Details
In questa dimostrazione, mostreremo come eseguire il provisioning di un volume NFS dalla riga di comando effettuando l'accesso a un cluster FSX tramite ssh come utente fsxadmin tramite l'IP di gestione del cluster FSX. In alternativa, è possibile allocare il volume anche utilizzando la console AWS FSX. Ripetere le procedure su altri file system FSX se sono configurati più file system FSX per adattarsi alle dimensioni del database.
-
Innanzitutto, eseguire il provisioning del volume NFS tramite CLI accedendo al cluster FSX tramite SSH come utente fsxadmin. Modificare l'indirizzo IP di gestione del cluster FSX, che può essere recuperato dalla console dell'interfaccia utente di AWS FSX ONTAP.
ssh fsxadmin@172.30.15.53 -
Creare un volume NFS con le stesse dimensioni dello storage primario per la memorizzazione dei file di dati del database Oracle VLDB primario copia dell'immagine.
vol create -volume ora_01_copy -aggregate aggr1 -size 100G -state online -type RW -junction-path /ora_01_copy -snapshot-policy none -tiering-policy snapshot-only -
In alternativa, è possibile eseguire il provisioning del volume dall'interfaccia utente della console AWS FSX con opzioni: Efficienza dello storage
Enabled, stile di sicurezzaUnix, Criterio SnapshotNone`E il tiering dello storage `Snapshot Onlycome mostrato di seguito.
-
Crea una policy di snapshot personalizzata per il database oracle con una pianificazione giornaliera e una conservazione di 30 giorni. È necessario modificare la policy in base alle proprie esigenze specifiche in termini di frequenza delle snapshot e finestra di conservazione.
snapshot policy create -policy oracle -enabled true -schedule1 daily -count1 30Applicare il criterio al volume NFS con provisioning per il backup incrementale e l'Unione RMAN.
vol modify -volume ora_01_copy -snapshot-policy oracle -
Accedere all'istanza EC2 come ec2-user e creare una directory /nfsfsxn. Creare ulteriori directory di mount point per file system FSX aggiuntivi.
sudo mkdir /nfsfsxn -
Montare il volume NFS FSX ONTAP sull'host dell'istanza DB EC2. Modificare l'indirizzo LIF NFS del server virtuale FSX. L'indirizzo lif NFS può essere recuperato dalla console dell'interfaccia utente di FSX ONTAP.
sudo mount 172.30.15.19:/ora_01_copy /nfsfsxn -o rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=262144,wsize=262144,nointr -
Modificare la proprietà del punto di montaggio in oracle:oisntall, quindi modificare il nome utente e il gruppo primario oracle in base alle necessità.
sudo chown oracle:oinstall /nfsfsxn
Impostare la fusione incrementale di Oracle RMAN sulla copia dell'immagine su FSX
Details
La fusione incrementale RMAN aggiorna continuamente la copia dell'immagine dei file di dati del database di staging a ogni intervallo incrementale di backup/Unione. La copia dell'immagine del backup del database sarà aggiornata quanto la frequenza di esecuzione del backup/Unione incrementale. Pertanto, prendere in considerazione le performance del database, gli obiettivi RTO e RPO quando si decide la frequenza del backup incrementale e dell'Unione RMAN.
-
Accedere all'istanza EC2 del server DB primario come utente oracle
-
Creare una directory oracopy sotto il punto di montaggio /nfsfsxn per memorizzare le copie delle immagini dei file di dati oracle e la directory archlog per l'area di ripristino flash Oracle.
mkdir /nfsfsxn/oracopymkdir /nfsfsxn/archlog -
Effettua l'accesso al database Oracle tramite sqlplus, attiva il tracciamento delle modifiche dei blocchi per un backup incrementale più rapido e modifica l'area di ripristino flash Oracle in FSxN mount se si trova attualmente sullo storage primario. In questo modo è possibile eseguire il backup del file di controllo predefinito RMAN/spfile autobackup e dei registri archiviati su FSxN NFS mount per il ripristino.
sqlplus / as sysdbaDal prompt di sqlplus, eseguire il seguente comando.
alter database enable block change tracking using file '/nfsfsxn/oracopy/bct_db1.ctf'alter system set db_recovery_file_dest='/nfsfsxn/archlog/' scope=both; -
Creare un backup RMAN e uno script di Unione incrementale. Lo script alloca più canali per il backup e l'Unione di Parallel RMAN. La prima esecuzione genererebbe la copia iniziale completa dell'immagine di riferimento. In un'esecuzione completa, il reparto IT rimuove prima i backup obsoleti che si trovano al di fuori della finestra di conservazione per mantenere pulita l'area di staging. Il file di log corrente viene quindi commutato prima dell'Unione e del backup. Il backup incrementale segue l'Unione in modo che la copia dell'immagine del database sia in grado di eseguire il processo di recupero dello stato corrente del database con un ciclo di backup/Unione. L'ordine di Unione e backup può essere annullato per un ripristino più rapido in base alle preferenze dell'utente. Lo script RMAN può essere integrato in un semplice script della shell da eseguire da crontab sul server DB primario. Assicurarsi che l'autobackup del file di controllo sia attivo nell'impostazione RMAN.
vi /home/oracle/rman_bkup_merge.cmd Add following lines: RUN { allocate channel c1 device type disk format '/nfsfsxn/oracopy/%U'; allocate channel c2 device type disk format '/nfsfsxn/oracopy/%U'; allocate channel c3 device type disk format '/nfsfsxn/oracopy/%U'; allocate channel c4 device type disk format '/nfsfsxn/oracopy/%U'; delete obsolete; sql 'alter system archive log current'; recover copy of database with tag 'OraCopyBKUPonFSxN_level_0'; backup incremental level 1 copies=1 for recover of copy with tag 'OraCopyBKUPonFSxN_level_0' database; } -
Sul server EC2 DB, accedere a RMAN localmente come utente oracle con o senza catalogo RMAN. In questa dimostrazione, non ci stiamo collegando a un catalogo RMAN.

Questa operazione completa la configurazione del backup e dell'Unione delle copie delle immagini di standby del database Oracle.
Passare Oracle DB alla copia dell'immagine per un ripristino rapido
Details
In caso di guasto dovuto a problemi di storage primario, come perdita o danneggiamento dei dati, è possibile passare rapidamente al database per la copia dell'immagine sul montaggio NFS di FSX ONTAP e ripristinarlo allo stato attuale senza ripristinare il database. L'eliminazione del ripristino dei supporti accelera enormemente il ripristino del database per un VLDB. Questo caso di utilizzo presuppone che l'istanza dell'host del database sia intatta e che il file di controllo del database, i registri archiviati e quelli correnti siano tutti disponibili per il ripristino.
-
Accedere all'host del server DB EC2 come utente oracle e creare una tabella di test prima di eseguire lo switch.

È possibile eseguire il database Oracle in FSX NFS Mount per un periodo prolungato senza penalizzare le performance, perché FSX ONTAP è uno storage ridondante di livello di produzione che offre performance elevate. Una volta risolto il problema dello storage primario, è possibile tornare indietro invertendo i processi incrementali di backup merge con tempi di inattività minimi.
Ripristino del database Oracle dalla copia dell'immagine a un host di istanza del DB EC2 diverso
Details
In caso di guasto in caso di perdita dello storage primario e dell'host dell'istanza del DB EC2, il ripristino non può essere eseguito dal server originale. Fortunatamente, sul file system NFS FSxN ridondante è ancora disponibile una copia dell'immagine di backup del database Oracle. È possibile eseguire rapidamente il provisioning di un'altra istanza EC2 DB identica e montare facilmente la copia dell'immagine del VLDB sul nuovo host EC2 DB tramite NFS per eseguire il ripristino. In questa sezione, illustreremo le procedure passo-passo per farlo.

Inserire una riga nella tabella di test creata in precedenza per il ripristino del database Oracle in una convalida host alternativa.

Arrestare l'host istanza DB EC2 primario per simulare un guasto totale dello storage e dell'host server DB.
-
Privison un nuovo host di istanze EC2 DB ora_02 con lo stesso sistema operativo e la stessa versione tramite la console AWS EC2. Configurare il sistema operativo kernal con le stesse patch dell'host del server DB EC2 primario, con gli RPM di preinstallazione Oracle e aggiungere spazio di swap anche all'host. Installare la stessa versione e le stesse patch di Oracle dell'host del server DB EC2 primario con opzione solo software. Queste attività possono essere automatizzate con il toolkit di automazione NetApp, come indicato nei link riportati di seguito.
Toolkit: "na_oracle19c_deploy"
Documentazione: "Implementazione automatica di Oracle19c per ONTAP su NFS" -
Configurare l'ambiente oracle in modo simile all'host dell'istanza primaria di EC2 DB ora_01, ad esempio oratab, orainst.loc e oracle user .bash_profile. È consigliabile eseguire il backup di questi file nel punto di montaggio NFS FSxN.
-
La copia dell'immagine di backup del database Oracle sul montaggio NFS FSxN viene memorizzata su un cluster FSX che copre le zone di disponibilità AWS per ridondanza, elevata avilabilità e performance elevate. Il file system NFS può essere facilmente montato su un nuovo server fino a quando la rete è raggiungibile. Le seguenti procedure montano la copia dell'immagine di un backup di Oracle VLDB su un host di istanza EC2 DB appena predisposto per il ripristino.
In qualità di utente ec2, creare il punto di montaggio.
sudo mkdir /nfsfsxnIn qualità di utente ec2, montare il volume NFS che ha memorizzato la copia dell'immagine di backup di Oracle VLDB.
sudo mount 172.30.15.19:/ora_01_copy /nfsfsxn -o rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=262144,wsize=262144,nointr -
Convalidare la copia dell'immagine di backup del database Oracle sul punto di montaggio NFS FSxN.

Per un ripristino più rapido, abilitare sessioni parallele con il parametro recovery_parallelism o specificare il grado di parallelismo nel comando di recovery per il ripristino del database: RECOVER DATABASE PARALLEL (DEGREE d INSTANCES DEFAULT);. In generale, i gradi di parallelismo devono essere uguali al numero di core della CPU sull'host. -
Uscire da RMAN, accedere a Oracle come utente oracle tramite sqlplus per aprire il database e reimpostare il log dopo un ripristino incompleto.

Altre attività di post-recovery
Add FSxN NFS mount to fstab so that the NFS file system will be mounted when EC2 instance host rebooted. As EC2 user, vi /etc/fstab and add following entry: 172.30.15.19:/ora_01_copy /nfsfsxn nfs rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=262144,wsize=262144,nointr 0 0 Update the Oracle init file from primary databse init file backup that is restored to /tmp/archive and create spfile as needed.
In questo modo viene completato il ripristino del database Oracle VLDB dalla copia dell'immagine di backup sul file system NFS FSxN a un nuovo host di istanze DB EC2.
Clonare la copia dell'immagine di standby Oracle per altri casi di utilizzo
Details
Un altro vantaggio offerto dall'utilizzo di AWS FSX ONTAP per la gestione temporanea della copia dell'immagine di Oracle VLDB è la possibilità di utilizzare FlexCloning per molti altri scopi con un investimento di storage aggiuntivo minimo. Nel seguente caso d'utilizzo, dimostreremo come eseguire lo snapshot e clonare il volume NFS di staging su FSX ONTAP per altri casi d'utilizzo Oracle, ad esempio SVILUPPO, UAT e così via

I processi di recovery sono ora simili al caso di utilizzo precedente di recovery per una nuova istanza di EC2 DB dopo un errore: Impostare l'ambiente oracle (oratab, Oracle_HOME, Oracle_SID) in modo che corrisponda all'istanza di produzione primaria, Creare un file init che includa db_recovery_file_dest_size e db_recovery_file_dest che puntino alla directory di ripristino flash sul montaggio NFS di FSX. Quindi, lanuch RMAN per eseguire il recovery. Di seguito sono riportati i passi dei comandi e l'output.
