Teradata MDS Logs
MDS Logs track error messages, warnings, and debug information on individual machines where the MDS software is installed. The MDS Log files can be found in the directory specified for the MDS Log File Location during installation (default is C:\mdslog).
For detailed installation information, see the Teradata Metadata Services Installation Guide (B035-3045).
The Teradata MDS Audit Trail is a table in the MDS repository that contains an audit trail of changes to the Teradata metadata. Entries are written to the table by the metaload utility. Entries are also written to the table by the MDS DDL Gateway Integrity Servers if the Automatic DIM Update feature is enabled. For each update to the DIM, an entry is inserted into the audit trail table when audit logging is enabled. For more information on enabling audit trail logging, see “Audit Log” on page 58.
The Teradata MDS Activity Log is a table in the MDS repository that, when activity logging is enabled, tracks user access (reads, writes, deletes) of objects in the repository. The log also indicates when access to an object is rejected because of permission conflicts. The Activity Log, unlike the Audit Trail, is not limited to only tracking changes to the DIM. For more information on enabling activity logging, see “Activity Log” on page 61.
The logs available through the Manage Services Logger feature of MDS Repository Explorer are intended primarily for Teradata support technicians and troubleshooting. Use only when instructed to do so by a Teradata support representative.
You can view the contents of both the Activity log and the Audit Trail when logged on as Administrator through MDS Repository Explorer or MetaManager, or by using SQL directly.
