SharePlex reports errors and other abnormal conditions in the following ways.
SharePlex reports operational errors, notices and warning conditions to the Event Log. This log provides a perpetual step-by-step record of replication activities, errors, and events. The Event Log can help you replay the sequence of events that led up to a problem.
Examples of replication events include:
Execution of a command in sp_ctrl. User-issued commands are recorded for every SharePlex command that is issued.
Note: A user-issued command appears in the Event Log as a notice, as in the following example:
Notice 08-07-02 16:13:24.641582 23696 1 User command: rjones activate config 1route (from mycomp14)
Login or logout of a user
Each entry in the Event Log includes:
To view the Event Log
Use the show log command in sp_ctrl or open the file named event_log in the log sub-directory of the SharePlex variable-data directory.
SharePlex provides a script for unattended monitoring of this log. For more information, see Monitor events with sp_eventmon.
Note: To control the number of out-of-sync messages that Post logs when a target table is very out-of-sync, use the SP_OPO_SYNC_LOG_FREQUENCY parameter. For more information, see the SharePlex Reference Guide.
The Status Database contains a summary of the conditions reported in the Event Log, including events that did not generate an error message or warning at the sp_ctrl user interface. This information alerts you to potential problems and helps you resolve existing ones. The Status Database may refer you to the Event Log for a more detailed explanation of a warning, notice or event.
To view the Status Database
Use the show statusdb command in sp_ctrl or open the file in the data sub-directory of the SharePlex variable-data directory.
When the Post process detects that source and target tables are out of synchronization, it logs the first 100 SQL statements and data for the out-of-sync transactions to an error file on the target system. You can use this log to determine the extent of the out-of-sync condition, and you can use the SQL statements to repair target tables if the condition is not too severe, after first correcting the cause of the problem.
To view the Error Log
Open the ID_errlog.sql file in the log sub-directory of the SharePlex variable-data directory (where ID is the identifier of the SharePlex target, for example a target database).
When a SharePlex process cannot process a record, the process not only logs the record to the Event Log, but also to its process log file. The process logs are primarily for use in debugging.
The name of a process log consists of the datasource identifier (such as the ORACLE_SID), the short name of the process (such as ocap, ord, opo, rcl), the file number, and the file extension (.log).
Examples:
Capture: ora10_ocap02.log
Read: ora10_ord01.log
Post: ora10_opo03.log
Reconcile: ora10_rcl01.log
The aging of old log files is performed in a circular pattern. The numbering begins with 01 and ends with 03. Up to three logs can exist at any time, including the current one. When all three logs are full (50 MB), the process starts overwriting them, beginning with the oldest one.
To view a process log
Open the file in the log sub-directory of the SharePlex variable-data directory.
When you activate a configuration, it generates a log.
To view the activation log
Open the file named SID_oconf##.log in the log sub-directory of the SharePlex variable data directory.
The compare and repair commands log errors, messages and warnings to a log. For more information about these logs, see the compare commands in the SharePlex Reference Guide.
