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

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

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
