本文件詳細說明如何使用自動化命令列介面( CLI )部署 Oracle 19c 。

CLI部署Oracle 19c資料庫

本節說明使用CLI準備及部署Oracle19c資料庫所需的步驟。請確定您已檢閱 "「使用入門與需求」一節" 並據此準備環境。

下載Oracle19c repo

  1. 從 Ansible 控制器執行下列命令:

    git clone https://github.com/NetApp-Automation/na_oracle19c_deploy.git
  2. 下載儲存庫之後、請將目錄變更為 na_oracle19c_deploy <cd na_oracle19c_deploy> 。

編輯hosts檔案

部署前請先完成下列事項:

  1. 編輯主機檔案na_oracle19c_deploy目錄。

  2. 在[ESI]下ONTAP 、將IP位址變更為叢集管理IP。

  3. 在[Oracle]群組下、新增Oracle主機名稱。主機名稱必須透過DNS或主機檔案解析為其IP位址、或必須在主機中指定。

  4. 完成這些步驟之後、請儲存任何變更。

以下範例說明主機檔案:

#ONTAP Host

[ontap]

"10.61.184.183"

#Oracle hosts

[oracle]

"rtpora01"

"rtpora02"

此範例執行方針、並在兩部Oracle資料庫伺服器上同時部署Oracle 19c。您也可以只用一部資料庫伺服器進行測試。在這種情況下、您只需要設定一個主機變數檔案。

註 無論您部署多少Oracle主機和資料庫、實戰手冊的執行方式都相同。

在host_vars下編輯host_name.yml檔案

每個Oracle主機的主機變數檔案都會以主機名稱識別、其中包含主機專屬的變數。您可以為主機指定任何名稱。編輯並複製「Host VARS Config(主機VARS組態)」區段中的「host_vars」、然後貼到您想要的「host_name.yml」檔案中。

註 必須變更藍色項目、以符合您的環境。

pdb_num: "3"
pdb_name: "{{ oracle_sid }}_pdb"

# CDB listener port, use different listener port for additional CDB on same host
listener_port: "1523"

# CDB is created with SGA at 75% of memory_limit, MB. Consider how many databases to be hosted on the node and how much ram to be allocated to each DB. The grand total SGA should not exceed 75% available RAM on node.
memory_limit: "5464"

# Set "em_configuration: DBEXPRESS" to install enterprise manager express and choose a unique port from 5500 to 5599 for each sid on the host.
# Leave them black if em express is not installed.
em_configuration: "DBEXPRESS"
em_express_port: "5501"

# {{groups.oracle[0]}} represents first Oracle DB server as defined in Oracle hosts group [oracle]. For concurrent multiple Oracle DB servers deployment, [0] will be incremented for each additional DB server. For example,  {{groups.oracle[1]}}" represents DB server 2, "{{groups.oracle[2]}}" represents DB server 3 ... As a good practice and the default, minimum three volumes is allocated to a DB server with corresponding /u01, /u02, /u03 mount points, which store oracle binary, oracle data, and oracle recovery files respectively. Additional volumes can be added by click on "More NFS volumes" but the number of volumes allocated to a DB server must match with what is defined in global vars file by volumes_nfs parameter, which dictates how many volumes are to be created for each DB server.
host_datastores_nfs:
  - {vol_name: "{{groups.oracle[0]}}_u01", aggr_name: "aggr01_node01", lif: "172.21.94.200", size: "25"}

  - {vol_name: "{{groups.oracle[0]}}_u03", aggr_name: "aggr01_node01", lif: "172.21.94.200", size: "25"}

編輯vars.yml檔案

vars.yml檔案整合了ONTAP 所有環境特定的變數(例如、Linux或Oracle)、以供Oracle部署。

  1. 編輯並複製VARS區段中的變數、然後將這些變數貼到您的「vars.yml」檔案中。

Each mount point dedicates to a particular Oracle files: u01 - Oracle binary, u02 - Oracle data, u03 - Oracle redo. Add additional volumes by click on "More NFS volumes" and also add the volumes list to corresponding host_vars as host_datastores_nfs variable. For multiple DB server deployment, additional volumes sets needs to be added for additional DB server. Input variable "{{groups.oracle[1]}}_u01", "{{groups.oracle[1]}}_u02", and "{{groups.oracle[1]}}_u03" as vol_name for second DB server. Place volumes for multiple DB servers alternatingly between controllers for balanced IO performance, e.g. DB server 1 on controller node1, DB server 2 on controller node2 etc. Make sure match lif address with controller node.

執行教戰手冊

在完成必要的環境先決條件、並將變數複製到「vars.yml」和「yer_host.yml」之後、您就可以開始部署教戰手冊了。

註 必須變更以符合您的環境。
  1. 傳送正確的標記和 ONTAP 叢集使用者名稱、以執行 ONTAP 教戰手冊。請填入 ONTAP 叢集的密碼、並在系統提示時填入 vsadmin 。

    ansible-playbook -i hosts all_playbook.yml -u username -k -K -t ontap_config -e @vars/vars.yml
  2. 執行 Linux 教戰手冊以執行部署的 Linux 部分。輸入管理 ssh 密碼和 Sudo 密碼。

    ansible-playbook -i hosts all_playbook.yml -u username -k -K -t linux_config -e @vars/vars.yml
  3. 執行 Oracle 教戰手冊以執行部署的 Oracle 部分。輸入管理 ssh 密碼和 Sudo 密碼。

    ansible-playbook -i hosts all_playbook.yml -u username -k -K -t oracle_config -e @vars/vars.yml

在相同的Oracle主機上部署額外的資料庫

每次執行時、實戰手冊的Oracle部分會在Oracle伺服器上建立單一Oracle Container資料庫。若要在同一部伺服器上建立其他容器資料庫、請完成下列步驟:

  1. 修改host_vars變數。

    1. 返回步驟3 -在「host_vars」下編輯「host_name.yml」檔案。

    2. 將Oracle SID變更為不同的命名字串。

    3. 將接聽程式連接埠變更為不同的號碼。

    4. 如果您已安裝EM Express、請將EM Express連接埠變更為不同的編號。

    5. 將修訂的主機變數複製並貼到Oracle主機變數檔案的「host_vars」下。

  2. 執行含有「oracle_config」標記的方針、如上所示 執行教戰手冊

驗證Oracle安裝

  1. 以 Oracle 使用者身分登入 Oracle 伺服器、然後執行下列命令:

    ps -ef | grep ora
    註 如果安裝已如預期完成、且Oracle資料庫已啟動、則會列出Oracle程序
  2. 登入資料庫、檢查使用下列命令集建立的資料庫組態設定和 PDB 。

    這證實 DNFS 運作正常。
