GoldenGate is a lightweight, log-based software. Interestingly, it’s popularly known as Oracle GoldenGate but it wasn’t initially an Oracle product. Oracle Golden Gate current release of it, 12.1.2, matches with the latest release of the Oracle database – 12c. The genesis of GoldenGate was inspired by its founders to make data replication happen easily, seamlessly, and not just between Oracle databases, but also between Oracle and non-Oracle databases. That’s why GoldenGate brings a very unique heterogeneous environment support. Enroll now and get certified in it.

✔ 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

✔ 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)?
