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

 Getting familiar with basic problems
 Developing the ability to deal with Extract and Replicatstartup issues
 Verifying file names, file permissions, consistency between Extract and Replicat group names and their supporting files
 Verifying consistent naming conventions 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 parameter file exists and 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

 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, and many columns listed in tables being replicated
 Introducing the use of the CacheMgr parameter to control the virtual memory and temporary disk space that is 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?

 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?

 Developing the ability to deal with and troubleshoot missed transactions involving issues such as Tables that are not properly specified – Missing” Add TranData” command – LOB data not replicating
 Analyzing the reasons why transactions are not being processed: Were the tables included in Table and Map statements? Are fully qualified names (owner. table) used for both Table and Map?
 ‘Single quotes’ on object names imply case-sensitive names for some databases (including the Oracle database)
 Are the transactions coming out of the source system properly?

 Developing the ability to deal with and troubleshoot mapping problems, such us: Fetching from the source data fails – Table and column names not matching between the source and the target
 Analyzing the causes of various mapping problems: Is Extract returning fetch-related errors? Was the row containing the data deleted?
Has the undo retention expired?
 Is “NoUseLatestVersion” for “FetchOptions” being used?
 Do the source and target tables exist in the databases? Are they specified correctly in the Table or Map statement? Are their names fully qualified (schema. table)?
 Do table and column names contain only supported characters?
 Are WHERE clauses comparing different data types?
 Is KeyCols being used? Are both source and target KeyCols being used? Corresponding source and target columns must match.

 Developing the ability to deal with and troubleshoot :
 SQLEXEC problems – File maintenance problems – Time differences – Too many open cursors
 File-Maintenance Problems: Discard File Is Not Created – Discard File Is Too Big – Trail File Is Too Big
 Miscellaneous Problems: Time Differences – INFO Command Shows Incorrect Status
