4.2 高级特性(2) -加密

1.对密码进行加密

GGSCI (db11) 3> ENCRYPT PASSWORD ogg ENCRYPTKEY DEFAULT
Using default key...

Encrypted password: AACAAAAAAAAAAADAHBLDCCIIOIRFNEPB
Algorithm used: BLOWFISH

得到加密的秘密后，修改参数文件

USERID ogg, PASSWORD "AACAAAAAAAAAAADAHBLDCCIIOIRFNEPB", ENCRYPTKEY default

用法举例：

2.加密trail文件

在参数文件中添加参数ENCRYPTTRAIL和DECRYPTTRAIL

先在源段的抽取进程参数文件中添加参数ENCRYPTTRAIL，这个参数一定要加载要加密的trail file之前

GGSCI (db11) 11> view param lhremd1

EXTRACT lhremd1
setenv(NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
USERID ogg, PASSWORD "AACAAAAAAAAAAADAHBLDCCIIOIRFNEPB", ENCRYPTKEY default
ReportCount Every 100 RECORDS, Rate 
Report at 22:45
ReportRollover at 21:57
DiscardFile dirrpt/LHREMD1.dsc, Append
DiscardRollover at 02:00 ON SUNDAY
DBOPTIONS ALLOWNOLOGGING 
ENCRYPTTRAIL 
EXTTRAIL ./dirdat/l1
TABLE hr.T; 

然后再在投递进程参数文件中进行解密后再加密远程trail file

GGSCI (db11) 13> view param phremd1

Extract PHREMD1 
------------------------------------------------------------------- 
-- Data Pump extract for HR schema 
------------------------------------------------------------------- 
PassThru 
DECRYPTTRAIL 
ENCRYPTTRAIL 
RmtHost 192.168.1.3, MgrPort 7809 
RmtTrail dirdat/l2 
Table HR.* ;

最后在目标端进行解密

GGSCI (10gasm) 9> view param rhremd1

Replicat RHREMD1 
------------------------------------------------------------------- 
-- Replicat for HR Schema 
------------------------------------------------------------------- 
SETENV (NLS_LANG = AMERICAN_AMERICA.AL32UTF8) 
USERID ogg, PASSWORD ogg
DiscardFile dirrpt/LHREMD1.dsc, Append 
DiscardRollover at 02:00 ON SUNDAY
HandleCollisions 
AssumeTargetDefs 
DECRYPTTRAIL
Map HR.T, Target HR.T ; 

重启所有的进程！
