goldengate配置文件裏面登入數據庫的密碼是明文的，這樣很不安全，我們需要對其加密
環境：redhat 5.7 oracle 11.2.0.3
beijing用戶，shenzhen用戶，tianjin用戶，shanghai用戶，4個用戶之間需要同步數據
ogg安裝目錄：
/ogg/beijing/
/ogg/shenzhen/
/ogg/tianjin/
/ogg/shanghai/
一：修改數據庫oggpro賬戶的密碼：
alter user oggpro identified by abc123;
二：生成密碼串：
cd /ogg/beijing/
./keygen 128 1
0x793E406328265C72A26E3861B7807147
將生成的密碼保存到OGG安裝目錄ENCKEYS文件中：
[oracle@rac01 beijing]$ more ENCKEYS
kasaur_key 0x793E406328265C72A26E3861B7807147
cp -rf ENCKEYS ../shenzhen/
cp -rf ENCKEYS ../tianjing/
cp -rf ENCKEYS ../shanghai/
三：根據修改後oggpro賬戶密碼生成密鑰：
GGSCI (rac01) 1> encrypt password abc123 encryptkey kasaur_key
AADAAAAAAAAAAAGATEQEMHNCCGDFKFYCAESDCDIBMGZGYENJXFIBQDWFQCLDYENAGHNCAEJBPIWGUBFA --beijing
AADAAAAAAAAAAAGALBGFSITATIHGIDACCEGAJJJEYIMHWHBDUAIJMDXEQHTECEQFAJGHGDBIWHDDNIOH --shenzhen
AADAAAAAAAAAAAGAMFCEPGNDRIXHEFPDRGAIYABGUDIETAXBXCAAIHNJGJJHLAUFHGDDLEICAEPHWDEF --tianjin
AADAAAAAAAAAAAGAQFQDUDIBNETGUCQGGABGVDYCRHRCIDEHKBDJFAACCIAGMENBBDYFOCLBRCCDZDBD --shanghai
測試登入數據庫：
GGSCI (rac01) 1> dblogin userid oggpro,password AADAAAAAAAAAAAGATEQEMHNCCGDFKFYCAESDCDIBMGZGYENJXFIBQDWFQCLDYENAGHNCAEJBPIWGUBFA,encryptkey kasaur_key --beijing
GGSCI (rac01) 1> dblogin userid oggpro,password AADAAAAAAAAAAAGALBGFSITATIHGIDACCEGAJJJEYIMHWHBDUAIJMDXEQHTECEQFAJGHGDBIWHDDNIOH,encryptkey kasaur_key --shenzhen
GGSCI (rac01) 1> dblogin userid oggpro,password AADAAAAAAAAAAAGAMFCEPGNDRIXHEFPDRGAIYABGUDIETAXBXCAAIHNJGJJHLAUFHGDDLEICAEPHWDEF,encryptkey kasaur_key --tianjin
GGSCI (rac01) 1> dblogin userid oggpro,password AADAAAAAAAAAAAGAQFQDUDIBNETGUCQGGABGVDYCRHRCIDEHKBDJFAACCIAGMENBBDYFOCLBRCCDZDBD,encryptkey kasaur_key --shanghai
四：修改OGG配置文件：
修改ogg配置文件（有多個同步用戶都需要拷貝ENCKEYS到對應ogg安裝目錄，都需要改配置文件密碼串對應生成的密鑰）密碼串位置如：
userid oggpro, password AADAAAAAAAAAAAGATEQEMHNCCGDFKFYCAESDCDIBMGZGYENJXFIBQDWFQCLDYENAGHNCAEJBPIWGUBFA,encryptkey kasaur_key --beijing
userid oggpro, password AADAAAAAAAAAAAGALBGFSITATIHGIDACCEGAJJJEYIMHWHBDUAIJMDXEQHTECEQFAJGHGDBIWHDDNIOH,encryptkey kasaur_key --shenzhen
userid oggpro, password AADAAAAAAAAAAAGAMFCEPGNDRIXHEFPDRGAIYABGUDIETAXBXCAAIHNJGJJHLAUFHGDDLEICAEPHWDEF,encryptkey kasaur_key --tianjin
userid oggpro, password AADAAAAAAAAAAAGAQFQDUDIBNETGUCQGGABGVDYCRHRCIDEHKBDJFAACCIAGMENBBDYFOCLBRCCDZDBD,encryptkey kasaur_key --shanghai
