✔ 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
