When ASM is used for an Oracle source endpoint, you should not be using a direct IP address to connect to the ASM.
Attempting to add multiple IP address connection strings into the ASM connection string field may lead to a connection failure with the following error:
SYS,GENERAL_EXCEPTION,Incorrect connection string for the thread 10
The TNS connection string of the ASM node cluster should be used for the ASM connection.
Correct Example:
(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=asmhostname)(PORT=1531))(CONNECT_DATA=(SERVICE_NAME=+ASM)))
Incorrect Example:
10.89.145.143:3100/+ASM,10.89.134.144:3100/+ASM
Resolution
The correct format of the ASM connection string should be used when using ASM with a cluster format.
