1、首先配置sourcedb上的nfs服务,oggstd上挂载sourcedb的online redo和archive log的目录
oggsource上配置：
vi /etc/exports
/u01/app/oracle 134.178.1.182(rw,no_root_squash,no_all_squash,sync)
save and exit
exportfs -r
linux 6.X
service nfs start
service rpcbind start
oggstd:
mkdir /mnt/test
mount -t nfs oggsource:/u01/app/oracle /mnt/test
2、配置oggstd到sourcedb的tnsname解析
oggstd: netca
3、配置logmap方式
ext1:
EXTRACT ext1
EXTTRAIL ./dirdat/er
userid goldengate@sourcedb, password goldengate
WILDCARDRESOLVE DYNAMIC
DYNAMICRESOLUTION
TRANLOGOPTIONS LOGSOURCE LINUX, PATHMAP /u01/app/oracle/oradata/sourcedb /mnt/test/oradata/sourcedb
--TRANLOGOPTIONS LOGSOURCE LINUX, PATHMAP /u01/app/oracle/oradata/sourcedb /mnt/test/oradata/sourcedb PATHMAP /u01/app/oracle/oradata/sourcedb/archdata /mnt/test/oradata/sourcedb/archdata
TRANLOGOPTIONS ALTARCHIVELOGDEST /mnt/test/oradata/sourcedb/archdata
table scott.*
dblogin userid goldengate@sourcedb, password goldengate
ADD EXTRACT ext1, TRANLOG, BEGIN NOW
ADD EXTTRAIL ./dirdat/er, EXTRACT ext1, MEGABYTES 10
几个注意点：
1、要求该机器上的字节存储顺序（Endian）和源库保持一致,32位和64位也保持一致；
2、手册上描述同时可以在PATHMAP中配置archivelog，但是测试下来貌似不行，我想这样配置：
TRANLOGOPTIONS LOGSOURCE LINUX, PATHMAP /u01/app/oracle/oradata/sourcedb /mnt/test/oradata/sourcedb, PATHMAP /u01/app/oracle/oradata/sourcedb/archdata /mnt/test/oradata/sourc
edb/archdata，
但是不行，所以借助ALTARCHIVELOGDEST；（有点类似于ALO）
3、LOGSOURCE - 设置的是源端操作系统，如：solaris->linux->solaris，借助中间机linux来抽取和pump trail到目标solais，这里设置LOGSOURCE SOLARIS
ALO模式：
（archivelog only模式）
上面的例子中只要改一下：
TRANLOGOPTIONS ARCHIVEDLOGONLY
TRANLOGOPTIONS ALTARCHIVELOGDEST PRIMARY /mnt/test/oradata/sourcedb/archdata
TRANLOGOPTIONS ALTARCHIVEDLOGFORMAT %t_%s_%r.dbf
FETCHOPTIONS, NOUSESNAPSHOT, NOUSELATESTVERSION, MISSINGROW REPORT
STATOPTIONS REPORTFETCH
table scott.*
