Oracle Database@ 中零 ETL 整合的先決條件AWS

設定零 ETL 整合之前，請確定您符合下列先決條件。

一般先決條件

Oracle 資料庫先決條件

您必須使用下列設定來設定 Oracle 資料庫。

複寫使用者設定

在您要複寫的每個可插入資料庫 (PDB) 中建立專用複寫使用者：

將下列許可授予複寫使用者。

-- For Autonomous Database on Dedicated Infrastructure only
ALTER USER GGADMIN ACCOUNT UNLOCK; 
ALTER USER GGADMIN IDENTIFIED BY ggadmin-password;

-- For Oracle Exadata only
GRANT SELECT ON any-replicated-table TO "ODBZEROETLADMIN";
GRANT LOGMINING to "ODBZEROETLADMIN";

-- Grant the following permissions to all services. 
-- For Oracle Exadata, use the ODBZEROETLADMIN user. For Autonomous Database on Dedicated Infrastructure,
-- use the GGADMIN user.
GRANT CREATE SESSION TO "ODBZEROETLADMIN";
GRANT SELECT ANY TRANSACTION TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$ARCHIVED_LOG TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$LOG TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$LOGFILE TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$LOGMNR_LOGS TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$LOGMNR_CONTENTS TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$DATABASE TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$THREAD TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$PARAMETER TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$NLS_PARAMETERS TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$TIMEZONE_NAMES TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$TRANSACTION TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$CONTAINERS TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_INDEXES TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_OBJECTS TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_TABLES TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_USERS TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_CATALOG TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_CONSTRAINTS TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_CONS_COLUMNS TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_TAB_COLS TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_IND_COLUMNS TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_ENCRYPTED_COLUMNS TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_LOG_GROUPS TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_TAB_PARTITIONS TO "ODBZEROETLADMIN";
GRANT SELECT ON SYS.DBA_REGISTRY TO "ODBZEROETLADMIN";
GRANT SELECT ON SYS.OBJ$ TO "ODBZEROETLADMIN";
GRANT SELECT ON DBA_TABLESPACES TO "ODBZEROETLADMIN";
GRANT SELECT ON DBA_OBJECTS TO "ODBZEROETLADMIN";
GRANT SELECT ON SYS.ENC$ TO "ODBZEROETLADMIN";
GRANT SELECT ON GV_$TRANSACTION TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$DATAGUARD_STATS TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$DATABASE_INCARNATION TO "ODBZEROETLADMIN";
GRANT EXECUTE ON SYS.DBMS_CRYPTO TO "ODBZEROETLADMIN";
GRANT SELECT ON SYS.DBA_DIRECTORIES TO "ODBZEROETLADMIN";
GRANT SELECT ON ALL_VIEWS TO "ODBZEROETLADMIN";
GRANT SELECT ON DBA_SEGMENTS TO "ODBZEROETLADMIN";
GRANT SELECT ON V_$TRANSPORTABLE_PLATFORM TO "ODBZEROETLADMIN";
GRANT CREATE ANY DIRECTORY TO "ODBZEROETLADMIN";
GRANT EXECUTE ON DBMS_FILE_TRANSFER TO "ODBZEROETLADMIN";
GRANT EXECUTE ON DBMS_FILE_GROUP TO "ODBZEROETLADMIN";
GRANT EXECUTE on DBMSLOGMNR to "ODBZEROETLADMIN";
GRANT SELECT on V_$LOGMNRLOGS to "ODBZEROETLADMIN";
GRANT SELECT on V_$LOGMNRCONTENTS to "ODBZEROETLADMIN";
GRANT LOGMINING to "ODBZEROETLADMIN";
GRANT SELECT ON GV_$CELL_STATE TO "ODBZEROETLADMIN";

補充記錄

在您的 Oracle 資料庫上啟用補充記錄，以擷取變更資料。

-- Check if supplemental logging is enabled
SELECT supplemental_log_data_min FROM v$database;

-- Enable supplemental logging if not already enabled.
-- For Oracle Exadata, enable supplemental logging on both the CDB and PDB.
-- For Autonomous Database on Dedicated Infrastructure, enable supplemental logging on the PDB only.
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;

-- For Autonomous Database on Dedicated Infrastructure only
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (PRIMARY KEY) COLUMNS;

-- Archive current online redo log
ALTER SYSTEM ARCHIVE LOG CURRENT;

若要設定 Oracle Database@AWS 與 Amazon Redshift 之間的零 ETL 整合，您必須設定 SSL。

AWS 服務先決條件

在設定零 ETL 整合之前，請設定 AWS Secrets Manager 並設定 IAM 許可。

設定 AWS Secrets Manager

將 Oracle 資料庫登入資料儲存在 AWS Secrets Manager 中，如下所示：

若要取得 TDE 金鑰 ID 和密碼，請使用支援加密方法中所述的技術，以使用 Oracle 做為 AWS Database Migration Service 的來源。下列命令會產生 base64 錢包。

base64 -i cwallet.sso > wallet.b64

下列範例顯示 Oracle Exadata 的秘密。對於 asm_service_name，111.11.11.11 代表 VM 節點的虛擬 IP。您也可以向 SCAN 註冊 ASM 接聽程式。

{
  "database_info": [
    {
      "name": "ODBDB_ZETLPDB",
      "service_name": "ODBDB_ZETLPDB.paas.oracle.com",
      "username": "ODBZEROETLADMIN",
      "password": "secure_password",
      "tde_key_id": "ORACLE.SECURITY.DB.ENCRYPTION.key_id",
      "tde_password": "tde_password",
      "certificateWallet": "base64_encoded_wallet_content"
    }
  ],
  "asm_info": {
    "asm_user": "odbzeroetlasm",
    "asm_password": "secure_password",
    "asm_service_name": "111.11.11.11:2484/+ASM"
  }
} 

下列範例顯示專用基礎設施上自治資料庫的秘密。

{
  "database_info": [
    {
      "database_name": "ZETLACD_ZETLADBMORECPU",
      "service_name": "ZETLADBMORECPU_high.adw.oraclecloud.com",
      "username": "ggadmin",
      "password": "secure_password",
      "certificateWallet": "base64_encoded_wallet_content"
    }
  ]
}

設定 IAM 許可

建立允許零 ETL 整合操作的 IAM 政策。下列範例政策允許描述、建立、更新和刪除 Exadata VM 叢集的操作。對於自治 VM 叢集，請使用 值cloud-autonomous-vm-cluster，而不是資源 ARN cloud-vm-cluster的值。
