with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work

or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Tanel Poder's Troubleshooting Scripts (TPT)
These sqlplus scripts are for Oracle Database performance optimization & troubleshooting.
Most of the scripts should be runnable directly from SQL Developer too.
### Getting Started & Videos
To get an idea of how I set up my client environment and use some of my main Oracle-related scripts, check out the videos here:
* [https://www.youtube.com/tanelpoder](https://www.youtube.com/tanelpoder)
Also you can follow me in Twitter as I'll post any noteworthy updates there:

-- Bug 12345717 - ORA-600 [13013] or hang/spin from MERGE into table with added column [ID 12345717.8]
--
-- ORA-600 [13013] can occur when executing a MERGE statement
-- with an UPDATE clause into a table which has had an ADD COLUMN
-- executed against it with a DEFAULT value with add column
-- optimization enabled.
--
--
-- Rediscovery Notes:
-- ORA-600 [13013] on a MERGE SQL.
-- In some cases this problem can also show up as a spin
-- executing a MERGE SQL against a table with an added column.
--
-- In both cases the problem can occur only if the target table has
-- a NOT NULL added column with a default value.
-- You can check this with SQL of the form below which shows such columns:
-- select owner, object_name, name
-- from dba_objects, col$
-- where bitand(col$.PROPERTY,1073741824)=1073741824
-- and object_id=obj#;
--
-- Workaround
-- Set _add_col_optim_enabled=false before adding columns
-- (this can cause the ADD COLUMN DDL to take longer as
-- all rows need updating)
-- For existing tables set the parameter then rebuild the table
-- to remove any existing optimized columns.
-- DROP TABLE tab1;
-- DROP TABLE tab2;

-- MOS: Bug 13250244 : ORA-4031 ERRORS SEEN WHEN PARAMETER _KGHDSIDX_COUNT IS SET TO >1 DUE TO MEM LEAK
-- ~~~~~~~~~~~~~
-- Testcase
-- ~~~~~~~~~~~~~~~~~
--
-- Files: BDETC.tar.Z (containing init.ora, setup.sql, tc.sql)
--
-- Steps:
-- ** IMPORTANT ** Merge init.ora into the pfile used to start the instance.
--
-- ie: Ensure the instance has _kghdsidx_count=4 set
--
--
-- sqlplus /nolog @setup
-- Creates a user TC with table FOO and a few stored outlines.
-- eg:
-- create table foo ( a number );
-- insert into foo values(10);
-- commit;
-- create index ifoo on foo(a);
-- analyze table foo compute statistics;
-- create sequence seq;
-- alter session set create_stored_outlines=true;
-- declare n number;
-- begin
-- for i in 1 .. 10 loop
-- execute immediate 'select count(*) from foo where a='||i INTO n;
-- end loop;
-- end;
-- /
--
-- sqlplus /nolog @tc
-- Sets USE_STORED_OUTLINES=TRUE and runs a load of literal selects.
-- eg:
-- alter session set use_stored_outlines=true;
-- declare n number;
-- begin
-- for i in 1 .. 40000
-- loop
-- select seq.nextval into n from dual;
-- execute immediate 'select count(*) from foo where a='||n INTO n;
-- end loop;
-- end;
-- /
--
-- Then flushes the shared pool and shows the number of 'STORED OUTLINE'
-- objects in V$DB_OBJECT_CACHE (ie: In the library cache).
-- eg:
-- select count(*) from v$db_object_cache
-- where namespace='STORED OUTLINE';
--
-- ^
-- After one run of tc.sql you will see there are many thousand
-- STORED OUTLINE objects in the library cache even after a flush
-- of the shared pool. These objects are not in use by anyone
-- but are not on the shared pool LRU so just accumulate "KGLHD"
-- space.
--
-- If you run tc.sql several times then eventually you will get
-- ORA-4031 errors as all free space is taken by the STORED OUTLINE
-- KGLHD handles.
--
--
-- Reproduced
-- ~~~~~~~~~~
-- Reproduced in 11.2.0.2
-- Reproduced in 11.2.0.3
-- Reproduced in RDBMS_MAIN_LINUX.X64_111025
--
--
-- Workaround/s
-- ~~~~~~~~~~~~
-- Use plan baselines and related 11g options to control the execution
-- plans instead of using stored outlines.
-- OR
-- The problem does not seem to occur if there is only one SGA subpool.
-- ie: Instance runs with "_kghdsidx_count"=1
-- (but setting this to 1 may affect shared pool concurrency on some systems)
--
-- The problem is aggravated by having USE_STORED_OUTLINES set for sessions
-- running literal SQL as each literal statement gets a STORED OUTLINE
-- handle , even if there is no matching outline (this is expected).
-- Hence avoiding literal SQL in sessions with USE_STORED_OUTLINES
-- can help reduce/eliminate any impact from this problem
-- eg: If the DB has CURSOR_SHARING=FORCE then the example test above
-- leaks no KGLHD STORED OUTLINE handles
--
--
-- Diagnostic Notes
-- ~~~~~~~~~~~~~~~~
-- If a session has USE_STORED_OUTLINES set then any SQL issued by the
-- session gets an outline handle, even if there is no actual outline.
-- This is normal and expected.
--
-- However,
-- It seems that if there is more than one shared pool subpool then
-- we somehow manage to get some stored outline handles left off of
-- the LRU list leading to a leak of KGLHD STORED OUTLINE handles over

-- File name: ash_wait_chains.sql (v0.8)
-- Purpose: Display ASH wait chains (multi-session wait signature, a session

--
-- Author: Tanel Poder
-- Copyright: (c) http://blog.tanelpoder.com
--
-- Usage:
-- @ash_wait_chains <grouping_cols> <filters> <fromtime> <totime>
--
-- Example:
-- @ash_wait_chains username||':'||program2||event2 session_type='FOREGROUND' sysdate-1/24 sysdate
--
-- Other:
-- This script uses only the in-memory G$ACTIVE_SESSION_HISTORY, use
-- @dash_wait_chains.sql for accessiong the DBA_HIST_ACTIVE_SESS_HISTORY archive
--
-- Oracle 10g does not have the BLOCKING_INST_ID column in ASH so you'll need
-- to comment out this column in this script. This may give you somewhat
-- incorrect results in RAC environment with global blockers.

PROMPT This is an experimental script as some documentation/explanation is needed.
PROMPT The ASH "delta" metrics are not tied to individual SQL_IDs or wait events,
PROMPT They are valid in the session scope (and related mostly static attributes,
PROMPT like PROGRAM, MACHINE, MODULE). Which SQL_ID/operation/event happens to be
PROMPT active when ASH samples its data is just matter of luck.
