The onlog utility displays the contents of a logical-log file on disk.
The onlog output is useful in debugging situations when you want to track a specific transaction or see what changes have been made to a specific tblspace. (For information about interpreting the logical-log file contents, see Interpreting Logical-Log Records.)
Any user can run all of the onlog options except the -l option. Only user informix can run the -l option.
If the database server is in offline mode when you execute onlog, only the files on disk are read. If the database server is in quiescent or online mode, onlog also reads the logical-log records stored in the logical-log buffers in shared memory (after all records on disk have been read).
When Extended Parallel Server is offline, you can perform onlog operations on specific coservers.
