到哪里去寻找Oracle Golden Gate的诊断线索?  这里只提供 troubleshooting的一些思路:


OGG troubleshooting way


Resources for finding information
GGSCI commands to view:
Processing status
Events
Errors
Checkpoints

GoldenGate reports and logs:
Process reports
Error log
Discard file
System logs



GoldenGate sends processing information to several locations to help you monitor processes and troubleshoot failures and unexpected results.
GGSCI - The GGSCI command interface provides several helpful commands for troubleshooting. For syntax, view the GGSCI online help by issuing the HELP command, or see the alphabetical reference in the GoldenGate for Windows and UNIX Reference Guide.
Process Reports - Each Extract, Replicat, and Manager process generates a report file showing:
    parameters in use                table and column mapping
    database information              runtime messages and errors
Event/Error log - The error log is a file that shows:
    a history of GGSCI commands         processes that started/stopped
    errors that occurred         informational messages
Discard file - GoldenGate creates a discard file when the DISCARDFILE parameter is used in the Extract or Replicat parameter file and the process has a problem with a record it is processing. The discard file contains column-level details for operations that a process could not handle, including:
  the database error message       
  the trail file sequence number
  the relative byte address of the record in the trail       
  details of the discarded record
System logs - GoldenGate writes operating-system-level errors to the Event Viewer on Windows or the syslog on UNIX. Errors appearing in the system logs also appear in the GoldenGate error log.




GoldenGate provides the following self-help tools:


GoldenGate Public Solutions Knowledge Base
Maintained by GoldenGate experts and accessible from the support site
GoldenGate Documentation
Configuration instructions and descriptions of GoldenGate errors, commands, parameters, and functions
SHOWSYNTAX parameter
Shows Replicat SQL statements
TRACE / TLTRACE parameters
Debugging feature to detect bottlenecks
Logdump utility
Tool for viewing and analyzing GoldenGate trails
Veridata?
High-speed table comparison solution

目前,即使生成了TRACE ,好像也无法分析吧?
