初始化工作

首先建立目錄：

$ sudo mkdir /u01/dumpdir $ sudo chown oracle:oinstall /u01/dumpdir

PDB數(shù)據(jù)庫中創(chuàng)建directory:

SQL> alter session set container=orclpdb1;Session altered.SQL> create directory dp_dir as '/u01/dumpdir';Directory created.SQL> set pagesize 0 SQL> select owner, directory_name, directory_path from dba_directories; SYS DP_DIR /u01/dumpdir SYS XMLDIR /u01/oracle/product/12.2.0.1/dbhome_1/rdbms/xml SYS XSDDIR /u01/oracle/product/12.2.0.1/dbhome_1/rdbms/xml/schema SYS ORA_DBMS_FCP_LOGDIR /u01/oracle/product/12.2.0.1/dbhome_1/cfgtoollogs SYS ORA_DBMS_FCP_ADMINDIR /u01/oracle/product/12.2.0.1/dbhome_1/rdbms/admin SYS OPATCH_INST_DIR /u01/oracle/product/12.2.0.1/dbhome_1/OPatch SYS ORACLE_OCM_CONFIG_DIR /u01/oracle/product/12.2.0.1/dbhome_1/ccr/state SYS DATA_PUMP_DIR /u01/oracle/admin/ORCLCDB/dpdump/878E05CEE9E952CAE0530100007F118F SYS ORACLE_OCM_CONFIG_DIR2 /u01/oracle/product/12.2.0.1/dbhome_1/ccr/state SYS OPATCH_SCRIPT_DIR /u01/oracle/product/12.2.0.1/dbhome_1/QOpatch SYS OPATCH_LOG_DIR /u01/oracle/product/12.2.0.1/dbhome_1/rdbms/log SYS ORACLE_BASE /u01/oracle SYS ORACLE_HOME /u01/oracle/product/12.2.0.1/dbhome_113 rows selected.

創(chuàng)建用戶dpuser，并賦予權(quán)限：

SQL> show con_name; ORCLPDB1 SQL> create user dpuser identified by "foo";User created.SQL> grant create session, create table to dpuser;Grant succeeded.SQL> grant read, write on directory dp_dir to dpuser;Grant succeeded. SQL> alter user dpuser quota 100m on users;User altered.

使用dpuser創(chuàng)建一些表：

$ sqlplus dpuser/foo@orclpdb1SQL*Plus: Release 12.2.0.1.0 Production on Sun Apr 28 16:35:32 2019Copyright (c) 1982, 2016, Oracle.

SQL> insert into foo values(1);1 row created.

導(dǎo)出測試：

$ expdp dpuser/foo@orclpdb1 directory=dp_dir tables=foo dumpfile=exp.dmp logfile=exp.logExport: Release 12.2.0.1.0 - Production on Sun Apr 28 16:40:19 2019Copyright (c) 1982, 2017, Oracle and/or its affiliates.

查看：

$ cd /u01/dumpdir/ $ ll total 188 -rw-r-----. 1 oracle oinstall 188416 Apr 28 16:40 exp.dmp -rw-r--r--. 1 oracle oinstall 1016 Apr 28 16:40 exp.log

導(dǎo)入測試：

先刪除表：

[oracle@oracle-12201-vagrant-dev ~]$ rlwrap sqlplus dpuser/foo@orclpdb1SQL*Plus: Release 12.2.0.1.0 Production on Sat May 4 18:23:40 2019Copyright (c) 1982, 2016, Oracle.

使用參數(shù)文件

注意用戶名userid的寫法：

[oracle@oracle-12201-vagrant-dev ~]$ cat exp.par userid=dpuser/foo@orclpdb1 directory=dp_dir dumpfile=exp.dmp logfile=exp.log tables=foo reuse_dumpfiles=y [oracle@oracle-12201-vagrant-dev ~]$ expdp parfile=exp.parExport: Release 12.2.0.1.0 - Production on Sat May 4 18:47:39 2019Copyright (c) 1982, 2017, Oracle and/or its affiliates.

更重要的一點(diǎn)是，即使執(zhí)行多次，結(jié)果都是一樣的，并非追加數(shù)據(jù)。

[oracle@oracle-12201-vagrant-dev ~]$ rlwrap sqlplus dpuser/foo@orclpdb1SQL*Plus: Release 12.2.0.1.0 Production on Sat May 4 18:49:03 2019Copyright (c) 1982, 2016, Oracle.

使用參數(shù)文件的一個好處是轉(zhuǎn)義會簡單些，例如使用SYS用戶的命令行為：

$ impdp 'sys/Abcdef_123456 as sysdba'

而使用參數(shù)文件則寫為：

$ cat expsys.par userid="sys/Abcdef_123456 as sysdba"

整庫導(dǎo)出

參數(shù)文件為：

[oracle@oracle-12201-vagrant-dev ~]$ cat exp.par userid="sys/Abcdef_123456 as sysdba" directory=dp_dir dumpfile=exp.dmp logfile=exp.log reuse_dumpfiles=y full=y

導(dǎo)出，第一次失敗是由于沒有為SYS用戶創(chuàng)建dump目錄。

$ expdp help=yExport: Release 12.2.0.1.0 - Production on Sat May 4 19:14:35 2019Copyright (c) 1982, 2017, Oracle and/or its affiliates. All rights reserved.The Data Pump export utility provides a mechanism for transferring data objects between Oracle databases. The utility is invoked with the following command:Example: expdp scott/tiger DIRECTORY=dmpdir DUMPFILE=scott.dmpYou can control how Export runs by entering the 'expdp' command followed by various parameters.

Valid keyword values are: [AES128], AES192 and AES256.ENCRYPTION_MODE Method of generating encryption key. Valid keyword values are: DUAL, PASSWORD and [TRANSPARENT].ENCRYPTION_PASSWORD Password key for creating encrypted data within a dump file.ENCRYPTION_PWD_PROMPT Specifies whether to prompt for the encryption password [NO]. Terminal echo will be suppressed while standard input is read.ESTIMATE Calculate job estimates. Valid keyword values are: [BLOCKS] and STATISTICS.ESTIMATE_ONLY Calculate job estimates without performing the export [NO].EXCLUDE Exclude specific object types. For example, EXCLUDE=SCHEMA:"='HR'".FILESIZE Specify the size of each dump file in units of bytes.FLASHBACK_SCN SCN used to reset session snapshot.FLASHBACK_TIME Time used to find the closest corresponding SCN value.FULL Export entire database [NO].HELP Display Help messages [NO].INCLUDE Include specific object types. For example, INCLUDE=TABLE_DATA.JOB_NAME Name of export job to create.KEEP_MASTER Retain the master table after an export job that completes successfully [NO].LOGFILE Specify log file name [export.log].LOGTIME Specifies that messages displayed during export operations be timestamped. Valid keyword values are: ALL, [NONE], LOGFILE and STATUS.METRICS Report additional job information to the export log file [NO].NETWORK_LINK Name of remote database link to the source system.NOLOGFILE Do not write log file [NO].PARALLEL Change the number of active workers for current job.PARFILE Specify parameter file name.QUERY Predicate clause used to export a subset of a table. For example, QUERY=employees:"WHERE department_id > 10".REMAP_DATA Specify a data conversion function. For example, REMAP_DATA=EMP.EMPNO:REMAPPKG.EMPNO.REUSE_DUMPFILES Overwrite destination dump file if it exists [NO].SAMPLE Percentage of data to be exported.SCHEMAS List of schemas to export [login schema].SERVICE_NAME Name of an active Service and associated resource group to constrain Oracle RAC resources.SOURCE_EDITION Edition to be used for extracting metadata.STATUS Frequency (secs) job status is to be monitored where the default [0] will show new status when available.TABLES Identifies a list of tables to export. For example, TABLES=HR.EMPLOYEES,SH.SALES:SALES_1995.TABLESPACES Identifies a list of tablespaces to export.TRANSPORTABLE Specify whether transportable method can be used. Valid keyword values are: ALWAYS and [NEVER].TRANSPORT_FULL_CHECK Verify storage segments of all tables [NO].TRANSPORT_TABLESPACES List of tablespaces from which metadata will be unloaded.VERSION Version of objects to export. Valid keyword values are: [COMPATIBLE], LATEST or any valid database version.VIEWS_AS_TABLES Identifies one or more views to be exported as tables. For example, VIEWS_AS_TABLES=HR.EMP_DETAILS_VIEW.------------------------------------------------------------------------------The following commands are valid while in interactive mode. Note: abbreviations are allowed.ADD_FILE Add dumpfile to dumpfile set.CONTINUE_CLIENT Return to logging mode. Job will be restarted if idle.EXIT_CLIENT Quit client session and leave job running.FILESIZE Default filesize (bytes) for subsequent ADD_FILE commands.HELP Summarize interactive commands.KILL_JOB Detach and delete job.PARALLEL Change the number of active workers for current job.REUSE_DUMPFILES Overwrite destination dump file if it exists [NO].START_JOB Start or resume current job. Valid keyword values are: SKIP_CURRENT.STATUS Frequency (secs) job status is to be monitored where the default [0] will show new status when available.STOP_JOB Orderly shutdown of job execution and exits the client. Valid keyword values are: IMMEDIATE.STOP_WORKER Stops a hung or stuck worker.TRACE Set trace/debug flags for the current job.
