Abstract: ORA-8103 BEING HIT DURING GATHERING OF STATISTICS ON TABLE PARTITION

PROBLEM:
--------
Provide the following:

1. Clear description of the problem encountered
ora-8103 is being hit at analyze of table partition

2. Pertinent configuration information (MTS/OPS/distributed/etc)

3. Indication of the frequency and predictability of the problem
Problem is not reproducable at will but frequency is high

4. Sequence of events leading to the problem
- truncate of multiple partitions
- populating new content in partitions
- gathering statistics per table partition 

5. Technical impact on the customer. Include persistent after effects. 
Failure in job as done, gathering of statistics at later timestamp is 
successful

DIAGNOSTIC ANALYSIS:
--------------------
1) double checked that gathering of statistics is done at partition level:
- checked the code of the customer: etl_load.sql + etl_util.sql
==> confirms that statistics are gathered at table level
==> logging as done confirms that statistics are gathered at table level
- checked the tracefile of a failing run (library_cache) + successful run 
==> confirms that statistics are gathered at table level

2) during the job run multiple partitions are being truncated 
(library_cache), the failing gathering of statistics is started in between

3) tried to reproduce the problem using the steps as done by customer but was 
not successful

WORKAROUND:
-----------
WorkAround is to gather statistics after all table manipulation (truncate + 
populate of data) has finished

RELATED BUGS:
-------------
bug:7011872 was created before to address this problem. events as asked in 
bug (10236 + 8103 ..) did generate a tremendous tracefile which only showed 
blockdumps in the 1st couple of Gb. 

REPRODUCIBILITY:
----------------
Although problem is not reproducable at will it does occur frequently

TEST CASE:
----------
Unfortunately there is no testcase available, have tried but was unsuccessful
