解決方式一：（Oracle 11g R1版本）
extract 的參數文件中加一行 TRANLOGOPTIONS ASMUSER <user>@<ASM_INSTANCE TNS>,ASMPASSWORD <ASM密碼>
註釋：
user必須sys用戶
ASM_INSTANCE TNS配置ASM實例TNSNAME如下：
ASM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.30.27.10)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME =+ASM) (INSTANCE_NAME =+ASM1) (UR=A)
(SERVER = DEDICATED)
)
)
ASM密碼 是SYS用戶密碼
解決方式二：（Oracle 10.2.0.5及更高版本10g R2版本以及Oracle 11.2.0.2及更高版本11g R2版本，現在可以使用新的AMS API）
Oracle GoldenGate的Extract使用以下方式訪問ASM：
TRANLOGOPTIONS DBLOGREADER
從Oracle Database 11.2.0.5.0及Oracle Database 11.2.0.2.0起，Oracle GoldenGate可以通過Database新的API訪問ASM中的Redo Log File及Archived Redo Log File，無需在GoldenGate的Extract配置文件中指定ASM的連接方式，也無需配置ASM的監聽。
Oracle Database使用以下Archive Log Dest參數：
log_archive_dest_1 歸檔獨立出來切勿放在閃回區。鄭州婦科醫院：http://yyk.familydoctor.com.cn/sysdfkyy/
