 、TROUBLESHOOTING
   1.ORA-28528:               
     [oracle][odbc sybase wire protocol driver]string data,right truncated.error in column 3.{01004}
    ora-02063:   2Line（  to_sybase)
   ORA-28528:
Heterogeneous Services datatype conversion error Cause: Either an Oracle datatype could not be converted to a non-Oracle datatype, or a non-Oracle datatype could not be converted to an Oracle datatype. The following are possible reasons for for the conversion failure: -- overflow problems (in the case of numbers) -- length limitations (in the case of character strings) -- invalid values passed into the conversion routines
Action: Contact customer support of the agent vendor. If the problem is due to size discrepancies between Oracle and the non-Oracle system, it may not be possible to convert the value

2.ora-28511:      sid=……           rpc  
ORA-28511:
lost RPC connection to heterogeneous remote agent using SID=string Cause: A fatal error occurred in one of the following places: -- the connection between the ORACLE server and the agent -- the heterogeneous services remote agent itself -- the connection to the non-Oracle system This error occurred after communication had been established successfully.
Action: Check for network problems and remote host crashes. The problem is probably in the agent software. If so, contact a customer support representative of the agent vendor.
