~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 
          Findings and Recommendations
          ----------------------------
 
Finding 1: Hard Parse Due to Literal Usage
Impact is 78.8 active sessions, 87.04% of total activity.
---------------------------------------------------------
SQL statements were not shared due to the usage of literals. This resulted in 
additional hard parses which were consuming significant database time.
 
   Recommendation 1: Application Analysis
   Estimated benefit is 78.8 active sessions, 87.04% of total activity.
   --------------------------------------------------------------------
   Action
      Investigate application logic for possible use of bind variables instead 
      of literals.
   Action
      Alternatively, you may set the parameter "cursor_sharing" to "force".
   Rationale
      At least 2447 SQL statements with FORCE_MATCHING_SIGNATURE 
      11111540808842783623 and PLAN_HASH_VALUE 1534564159 were found to be 
      using literals. Look in V$SQL for examples of such SQL statements.
   Rationale
      At least 1390 SQL statements with FORCE_MATCHING_SIGNATURE 
      11574536825851767243 and PLAN_HASH_VALUE 1421812382 were found to be 
      using literals. Look in V$SQL for examples of such SQL statements.
   Rationale
      At least 158 SQL statements with FORCE_MATCHING_SIGNATURE 
      17588589506158663903 and PLAN_HASH_VALUE 1421812382 were found to be 
      using literals. Look in V$SQL for examples of such SQL statements.
   Rationale
      At least 145 SQL statements with FORCE_MATCHING_SIGNATURE 
      3836291656695528921 and PLAN_HASH_VALUE 1421812382 were found to be 
      using literals. Look in V$SQL for examples of such SQL statements.
   Rationale
      At least 57 SQL statements with FORCE_MATCHING_SIGNATURE 
      15725224174066296020 and PLAN_HASH_VALUE 3364108953 were found to be 
      using literals. Look in V$SQL for examples of such SQL statements.
 
   Symptoms That Led to the Finding:
   ---------------------------------
      Hard parsing of SQL statements was consuming significant database time.
      Impact is 78.81 active sessions, 87.05% of total activity.
 
 
Finding 2: Shared Pool Latches
Impact is 47.54 active sessions, 52.51% of total activity.
----------------------------------------------------------
Contention for latches related to the shared pool was consuming significant 
database time.
Waits for "library cache: mutex X" amounted to 44% of database time.
Waits for "latch: shared pool" amounted to 7% of database time.
 
   No recommendations are available.
 
   Symptoms That Led to the Finding:
   ---------------------------------
      Wait class "Concurrency" was consuming significant database time.
      Impact is 69.99 active sessions, 77.3% of total activity.
 
 
Finding 3: Unusual "Concurrency" Wait Event
Impact is 21.62 active sessions, 23.88% of total activity.
----------------------------------------------------------
Wait event "row cache mutex" in wait class "Concurrency" was consuming 
significant database time.
 
   Recommendation 1: Application Analysis
   Estimated benefit is 21.62 active sessions, 23.88% of total activity.
   ---------------------------------------------------------------------
   Action
      Investigate the cause for high "row cache mutex" waits. Refer to 
      Oracle's "Database Reference" for the description of this wait event.
 
   Recommendation 2: Application Analysis
   Estimated benefit is 21.62 active sessions, 23.88% of total activity.
   ---------------------------------------------------------------------
   Action
      Investigate the cause for high "row cache mutex" waits in Service 
      "conndemo".
 
   Recommendation 3: Application Analysis
   Estimated benefit is 16.69 active sessions, 18.43% of total activity.
   ---------------------------------------------------------------------
   Action
      Investigate the cause for high "row cache mutex" waits with P1 ("cache 
      id") value "10" and P2 ("where requested") value "19".
 
   Recommendation 4: Application Analysis
   Estimated benefit is 10.96 active sessions, 12.11% of total activity.
   ---------------------------------------------------------------------
   Action
      Investigate the cause for high "row cache mutex" waits in Module 
      "java@scao08adm03.us.oracle.com (TNS V1-V3)".
 
   Recommendation 5: Application Analysis
   Estimated benefit is 10.66 active sessions, 11.78% of total activity.
   ---------------------------------------------------------------------
   Action
      Investigate the cause for high "row cache mutex" waits in Module 
      "java@scao08adm02.us.oracle.com (TNS V1-V3)".
 
   Symptoms That Led to the Finding:
   ---------------------------------
      Wait class "Concurrency" was consuming significant database time.
      Impact is 69.99 active sessions, 77.3% of total activity.
 
 
Finding 4: Soft Parse
Impact is 8.25 active sessions, 9.11% of total activity.
--------------------------------------------------------
Soft parsing of SQL statements was consuming significant database time.
 
   Recommendation 1: Application Analysis
   Estimated benefit is 8.25 active sessions, 9.11% of total activity.
   -------------------------------------------------------------------
   Action
      Investigate application logic to keep open the frequently used cursors. 
      Note that cursors are closed by both cursor close calls and session 
      disconnects.
 
   Recommendation 2: Database Configuration
   Estimated benefit is 8.25 active sessions, 9.11% of total activity.
   -------------------------------------------------------------------
   Action
      Consider increasing the session cursor cache size by increasing the 
      value of parameter "session_cached_cursors".
   Rationale
      The value of parameter "session_cached_cursors" was "50" during the 
      analysis period.
 
 
 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
          Additional Information
          ----------------------
 
Warnings
--------
The impact of cursors being aged out of the shared pool cannot be determined 
because of changes in the shared pool size.
 
Miscellaneous Information
-------------------------
Wait class "Application" was not consuming significant database time.
Wait class "Cluster" was not consuming significant database time.
Wait class "Commit" was not consuming significant database time.
Wait class "Configuration" was not consuming significant database time.
CPU was not a bottleneck for the instance.
Wait class "Network" was not consuming significant database time.
Wait class "User I/O" was not consuming significant database time.
The network latency of the cluster interconnect was within acceptable limits 
of 1 milliseconds.
Session connect and disconnect calls were not consuming significant database 
time.
