ORA-13786 missing SQL text of statement object %s for tuning task %s

While implementing one sql tuning advice from OEM came across following error:

ORA-13786 missing SQL text of statement object %s for tuning task %s" when Accepting a SQL Profile for a Parallel Execution Plan

In order to identify exact error, query the view dba_advisor_rationale

SQL> select message from dba_advisor_rationale where object_id=<object number from error>;

MESSAGE

--------------------------------------------

This attribute enables parallel execution.

The message clearly states it's sql plan enables the parallel execution of query which needs extra attribute in the statement to proceed.

In order to re-produce the error on the database run the following commands:

EXEC dbms_sqltune.accept_sql_profile(task_name => 'SYS_AUTO_SQL_TUNING_EXAMPLE', object_id => 2);

ORA-13786: missing SQL text of statement object "1" for tuning task "SYS_AUTO_SQL_TUNING_EXAMPLE"

SQL> select message from dba_advisor_rationale where object_id=2;


MESSAGE

--------------------------------------------

This attribute enables parallel execution.


In order to apply this sql profile you need to add profile_type as PX_PROFILE to the above statment.

EXEC dbms_sqltune.accept_sql_profile(task_name => 'SYS_AUTO_SQL_TUNING_EXAMPLE', object_id => 2,profile_type => DBMS_SQLTUNE.PX_PROFILE);


Above statement should serve the purpose and needed for a SQL Profile with a change to parallel execution and REGULAR_PROFILE value without a change to parallel execution.

How to Solve - "WAIT FOR EMON PROCESS NTFNS"

Event Monitor Process in short called as EMON is generally used by oracle to send notification. Often applications uses Database Change Notification process also called as DBCN to be aware of changes in the database, based on these notifications they take further actions. Often clients subscribe to the database and notifications are send as callback to them. In some cases you will notice database sessions are showing wait event "WAIT FOR EMON PROCESS NTFNS" and it can even make your database un-responsive. One observation can be these processes are taking more CPU (may not in be in all cases). As stated EMON process deals with database notification and it's spawn and gets down itself and Administrators have no control on theses processes. Anyone can go through oracle documents to read more EMON functioning process.  EMON uses oracle advanced queues and database queue notifications into them and EMON process these notifications to clients based on their subscriptions.

Query Regression - "OR" Transformation Oracle 19c

Recently while upgrading Oracle Database from version 12.1 to 19.10 found there were couple of queries which was running slow post upgrade. Usually these type of behavior is seen while upgrading to newer version and oracle provide various ways to fix them. The difference between good and bad plan was an introduction of  "MERGE JOIN CARTESIAN" (aka MJC) and that's in where regressed query in 19c taking most of the time. MJC sometimes works for queries but in this case it was clearly not helping.  We had following options here:     1. Copy the profile from 12c to 19c database and it worked, but the problem was not just to specific query but with many similar query. This means profile option is not very attractive in this case.     2. We also tried running query with OFE 12.1 to use the same optimizer features as previous version and query behaves well. Though this option can't be placed as we need to use 19c OFE and can be placed only for testing purpose.           alte

ORA - 12537: TNS: connection closed

Often when active clone to be done to create a new environment, we land up into couple of issues. I will discuss about one issues during this process.
