Oracle GoldenGate Troubleshooting Tools

Accessing knowledge Documents - Mailing lists, Oracle GoldenGate forums, etc.
Consulting the Documentation
Getting familiar with the ShowSyntax parameter
Getting familiar with the logdump utility

Basic and Startup Problems

Getting familiar with basic problems
Developing the ability to deal with Extract and Replicat startup issues
Verifying file names, file permissions, consistency between Extract and Replicat group names and their supporting files
Verifying consistent naming convention when defining trail files and their reference in the Extract/Replicat parameter files
Verifying that the correct software version has been installed
Verifying that the Oracle GoldenGate manager is running, that the group name which fails to start exists and is not misspelt
Verifying that the the parameter file exists, has the same name as the Extract/Replicat group, and is accessible by Oracle GoldenGate
Introducing the use of CHECKPARAMS to verify that the parameter syntax is correct

Data Extraction Problems

Developing the ability to deal with and troubleshoot data extraction issues:Extract is slow - Extract abends - Data pump abends
Analyzing various causes of a slow Extract startup
Tracing may be enabled, activity logging may be enabled, many columns listed in tables being replicated
Introducing the use of the CacheMgr parameter to control the virtual memory and temporary disk space that are available for caching uncommitted transaction data
In-depth analysis of abending Extracts: is Extract unable to open the transaction logs? - Checking to see if the disk is full -Is an archive log missing?
In-depth analysis of abending data pumps: Does the data pump abend with error number 509 ("Incompatible record")?Have the source tables been changed? Is the Extract abending due to data manipulation?
Was the primary Extract or the data pump stopped, re-added, or restarted without resetting the data pump’s read position in the local trail?

Data Replication Problems

Developing the ability to deal with and troubleshoot data replication issues:
Analyzing the various causes of a "stuck" Replicat: Does "Stats Replicat" return no statistics? Do successive "Info Replicat" commands indicate that the Replicat read checkpoint is not moving?
Verifying that the Replicat is reading the trail to which Extract is writing
Analyzing the reasons why a Replicat abends: Is Replicat unable to locate a trail? Is Replicat unable to open a trail file? Was "Add TranData" issued for each table?
