PURPOSE:

This document provides information on bugs known to cause "wrong results". "Wrong results" in this context has quite a broad classification - it may be a performance monitoring view giving slightly misleading information, or may be completely wrong rows returned (or missing) from a query result set. 
These issues can be particularly difficult to match to a known bug as the symptom often depend on the query. The aim here is to provide a list of bugs known to cause wrong results and to provide both version affected and radio options to trim the list.

Documented Database Bugs With High “Solved SR” Count

2017-02-02 没有评论

APPLIES TO:

Oracle Database - Enterprise Edition - Version 9.2.0.8 and later

1	Oracle Database - Enterprise Edition - Version 9.2.0.8 and later

PURPOSE:

This note lists "documented" database bugs that have been marked as the solution to a "high number of Service Requests".
For the purpose of this listing:
A "documented" bug means one with a bugno.8 KM document created from BugTag data.
A "high number of Service Requests" means that there are more than 50 "Solved SR" entries for the bug - ie: all bugs in this doc have > 50 "Solved SR" entries from the SR closure data.
It is suggested to restrict the list based on the version of interest, and then use the radio buttons to check on particular features / symptoms / facts linked to the bug descriptions.

The list includes some bugs with a "D" in the "NB" column - this is used to denote a bug fix that is DISABLED by default and so a customer may encounter that issue in DB versions where the bug is marked as fixed.

PURPOSE:

In recent quarters, during non-code closure bug review for Performance, it was found that more than 50% of duplicates (36,96) closed by Sustaining Engineering (SE) belonged to version 12.1. As a result this document was created to list most commonly reported and share this with Tier-1 engineers so that they could check this before logging any new bugs. Thus the Goal of this document is to provide a list of known bugs reported in 12C for database & SQL performance for support analysts to check before logging new bugs.

In addition to the bugs listed in this article, there is also a useful list of Documented Database Bugs With High "Solved SR" Count where a high number of Service Requests means that there are more than 50 "Solved SR" entries for the bug - ie: all bugs in this doc have > 50 "Solved SR" entries.” :
