52:24
Click on SHOW MORE for video highlights! Products and functionality covered in the Autonomous Health Framework's (AHF) family include the Applied Machine Learning-based products of Cluster Health Advisor (CHA), Hang Manager (HM) and Trace File Analyzer (TFA), as well as performance management and continuous availability functionality in ORAchk/EXAchk, Memory Guard, Cluster Health Monitor Cluster Verification Utility and QoS Management. The session covers the new Trace File Analyzer Service that is part of Oracle Database 18c. 03:32 - What is Oracle’s goal in developing the TFA Service?05:50 - Is TFA available on ODA and is it licensed for Standard Edition? 07:10 - When to use TFA and when to use IPS? 09:31 - How do you envision its integration into Operations? 11:18 - Does it connect to Oracle Support Services? 12:18 - Which type of events show up in its timeline? 13:39 - What actions can I take on these events? 16:45 - Can I get alerted to these events? 17:30 - What is considered an Anomaly? 20:26 - How do I know whether it is good or bad? 23:55 - What is the best way to make use of the Anomaly Timeline? 26:30 - How do I get this service? 28:52 - Is the 18c DSC TFA different from the standalone TFA that I download from Oracle? If so, how do I upgrade the DSC TFA? 31:34 - So if we upgrade GI to 18.x will TFA upgraded as well or do we upgrade TFA additionally? 33:00 - Does it only work with Oracle 18.3 and later databases and GI? 34:40 - Can I get this in the latest MOS version? 35:38 - Does it require initial configuration post installation?37:50 - Does the TFA Service on the DSC have a UI? 39:00 - Does it require specific browsers or plugins? 39:15 - Is the TFA Service is an Oracle Cloud offering or it is a built-in function within the DSC? 41:06 - Which users have access to it? 42:35 - Is lifecycle management of the repository automatic? 44:40 - Is it integrated with Enterprise Manager? 45:22 - Is it integrated with ORAchk/EXAchk? 47:05 - Is there any plan to integrate with DBSAT? 48:32 - Does it require any special or paid Oracle licenses? 50:02 - How do you see this integrating with other AHF components?

Working with the Trace File Analyzer Collector
 
28:22
The Trace File Analyzer (TFA) Collector Tool is a utility for collecting first failure diagnostics when creating Service Requests with Oracle Support. Using TFA Collector to make diagnostic collections removes questions about what files to collect and upload. TFA knows about all the well known Oracle and operating system diagnostic locations and collects only files that have been modified proximate to problem time specified from any of those well known locations. Larger files are also pruned proximate to problem time specified to reduce the size of the upload. If the system is a clustered environment TFA collects relevant diagnostics from the remote nodes as well. All of this can be accomplished with one simple command. Key features of TFA Collector include: RAC and single instance non-RAC support Time-based collection of relevant files OS Clusterware ASM DB OSW and CHMOS etc Large file pruning Cluster-wide time-relevant collections Analytics for key files DB alert logs Clusterware alert logs ASM alert logs system messages OSWatcher top and slabinfo data Flexible command-line interface Copyright © 2014 Oracle and/or its affiliates.

Tracing: Transaction ST12 = Combination of two transactions . SAT (ABAP Trace) , ST05 = SQL Trace SQL Trace: To monitor the database access of reports and transactions. Less common traces : Enqueue Trace: (the locking system),RFC Trace, Table buffer trace: Performance Improvements ABAP Coding: Keep an eye on those loops. Select statements in loops = absolutely avoid = use for all entries instead Function call, or performs in loops = re - visit and see if you can optimize The "READ TABLE" statement Sorted table- Binary search .. Or even better use "Index" on internal tables. Use mass operations on internal table = internal table copy one to another, Append lines of int_fligh1 to int_fligh2. Use field symbols to modify internal table in a loop (minor improvement ) A little trick if you call performs in a loop:: Use static variables Avoid sleep, wait etc commands.. Or synchronous RFC calls 2)Database bottleneck Use Indexes : Make sure Indexes are being used in your select statement (check with trace if needed) Extreme case , create new index (this has the disadvantage of making the insert slower) Select -- End select loop : Usually database optimiser will fix it, still avoid it Select * into corresponding fields = about a millisecond slower Make clever use of inner joins Use views Use (max,min, avg): example : Select max( flightnum ) from flight . GET RUN TIME command Reduce I/O first, then memory, then CPU activity.Field-groups can be useful for multi-level sorting and displaying. However, they write their data to the system's paging space, rather than to memory (internal tables use memory)

Can you flashback table into SYSTEM tablespace?
 
10:02
Flashback feature in Oracle database is well known to roll back the table to a specific timestamp (depends on undo retention) or to restore dropped table and many more. We must have used this flashback feature so far on application schema objects and found working without any issues. As an Oracle DBA did you configure any tools (might be monitoring, RMAN catalog or any) with objects created in SYSTEM tablespace? If so, you probably would see some problems later when you need to use Flashback on these objects though they are not Oracle supplied objects. Let us go through a case study which will clearly explain you the functionality of Flashback table. Did you like the video? Subscribe now, Like it and share it.
