  What, exactly, is your question?

  Literally ask you which of these 2 methods is new?  As mentioned above, none is really new.  Both participated in Oracle at least 13 years.

  Query 1, above, ANSI join syntax uses, which is more recent.   As mentioned above, Oracle has started to support that the syntax in version 9.1 (2001) previous versions only supported syntax used in query 2.

  Did you mean to ask something else?  Maybe "How can I use a query as a query 1 forms?" or "are there other places where a method works, but the other is not?

• Setting sql plans

  Hello, I'm on 11 GR 2 and I was wondering if there is way I could plan attached to a sql_id sql based on a hash value of the plan? What I have is a sql with a sql_id which has two hash values of plan attached to the same sql_id and plan with hash value a1 is ok plan annexed to the sql_id even with the hash value a2 is unoptimal, with high cost and sql is wrong with this hash values. So I will try to find, is there a way to correct a good plan for a sql_id based on a hash value?

  To do this, you can use a SQL Plan basis or a SQL profile.

  For a profile of SQL, see script COE_XFR_SQL_PROFILE. SQL (Oracle Support id doc 215187.1) SQLT that takes a sql id and the hash value of plan that you want to apply.

• SQL PLAN Management

  In Oracle 11 g, I want to use sql plan management to achieve stability of the regime. My problem is that I don't know what all the plans, users can run, then I put

  OPTIMIZER_CAPTURE_SQL_PLAN_BASELINES=TRUE

  But then sysaux tablespace keeps growing. I started with 2GB and now I have SYSAUX tablespace of 12GB. Is there anyway to say that only plans in certain parsing schema are automatically captured and no recursive statements to data dictionary etc. are captured. I am only interested in sql plans run by my program and not those sql statements internally generated by Oracle. I want all of this to be automatic, that’s why I set above parameter to TRUE. If that is not the right approach, what other options I have.

  The simple answer is probably that if you want to capture base lines of sql plan for a subset of users or programs, and then set the parameter to the level of the system to false and use a logon trigger to true for sessions with the subset of attributes you have defined.

  However, depending on the exact version of 11 g, there are a number of bugs affecting both the performance and the storage of the basic mechanism worth overlap Oracel version with lists of related bugs in the support Web site.

  Also double check on the occupants of the tablespace SYSAUX because the base lines are not the only thing in there that can use a significant amount of space.

• Issue of SQL Plan Management

  Hello
  
  I have a question concerning the presence of 'Accepted' indicator (values or NOT) that is displayed by the function dbms_xplan.display_sql_plan_baseline.
  
  It is my understanding of the documentation of Oracle SQL plan does not become part of a plan SQL database until it is accepted by the process of evolution or manual loading in the base line. How is it possible to have a plan to be part of a reference that is not accepted? If the dbms_xplan.display_sql_plan_baseline function is used to display more than plans that are in a reference database and that are only in the story?
  
  
  Thanks for your thoughts on this.
  
  Richard
  
  PS. I use Oracle 11.1.0.7

  View code that you use to call the function and the result you get.

  Depending on how you call the function, and what plans are available, you will get different results. For example
  >
  plan_name
  Name of plan. It identifies a specific plan. Value default NULL means that all the plans associated with identified SQL statement are explained and displayed
  >
  You specify this setting? If this isn't the case, then all THE plans could include plans that have not been accepted.

  Section 15.5 display SQL Plan baseline in the Performance Tuning Guide contains an example of this and displays two plans: an accepted and the other not.
  http://docs.Oracle.com/CD/E11882_01/server.112/e16638/optplanmgmt.htm

  It's really the history display that includes all plans.

• How to age a sql plan?

  Hello
  I have a query that has a sql plan. Is there a way to age on the denunciations of the analysis of the cache or cause oracle to recalculate the plan sql?

  Insaponata wrote:
  I can not make structural changes... there at - it another way?

  I don't understand you not entirely, but the runtime of CBO, check if there may be a more effective plan if yes then it will generate the new plan. Even rinse you all the plans of the shared pool (using ALTER SYSTEM EMPTY POOL SHARED) then oracle will make analysis difficult when running query and then generated new and old plan will be even (if it is not happen over the case). What exactly is your want to do? Please explain more.

  All it seems a little weird. You can think of to raise a ticket with the Support of Oracle.

  In the source database, can you show the output of

  SELECT * FROM v$version;
  SELECT * FROM dba_sql_plan_baselines;
  SELECT * FROM test_baseline_15july_2;
  

  In the destination database, can you show the output of

  SELECT * FROM v$version;
  SELECT * FROM test_baseline_15july_2;

• What metrics to use for memory capacity planning? Active or consumed (in request or use vROPS)

  Hey all,.

  I was wondering once more what metrics to use for memory capacity planning. Since the information from different sources (for example your ESXi host needs more RAM to Iwan Rahabok or VMworld 2012: Session VSP1729 - virtualized memory understanding performance management - Eric Sloof - NTPRO.NL Kit Colbert) pointing all assets (vROPS request), I expect that when we have high memory consumption / use in vCenter there will be no balloon / compression / permutation.

  Also the metric active / request should not be used for all workloads (e.g. Java / DB), why is - this? I have not found the reason of this anywhere, only the fact.

  Other sources such as Mark Achtemichuk suggests using consumed/use, which is the opposite (Understanding Active Memory - VMware vSphere Blog - Articles VMware vSphere).

  So I thought I'll with active / demand as metric and ignoring the warnings inside of vCenter.

  But the last time we have fixed half of our group, we had consumed/high memory usage and the vCenter began to inflate, compress, and finally to Exchange. Not a lot but I had not expected that, because memory active was only a small percentage of consumed.

  Can someone explain to me why this happened and who is right on this issue.

  Kind regards

  jengl

  jengl I don't know if you asked the wrong question, or I give the wrong answer :-)

  It is always good to attach screenshots, background to the issues, and what exactly you are trying to solve.

  You wrote:

  So to summarize:

  -ESXi uses consume to decide when to start the recovery techniques of memory RAM

  -To rightsize VMs for RAM, you must use the counter inside the BONE, not active

  -If you do not want to commit too much RAM and have a lot of the balloon you should right-size your virtual machines or extend the RAM / buy additional servers

  Please correct me if I'm wrong.

  My answer: you are right. If you do not have access to the guest operating system, then Active VM and VM consumed are better guess. Better than nothing :-)

  Sizing sizing of VM and ESXi are 2 different things (2 use cases) different. Please don't mix up the as soon as they are confusing. Do not try to resize the virtual machine when you are sizing the ESXi, unless you have a control total on them.

  You wrote:

  The question for me is: how many cache (standby under Windows) inside the VM is really necessary for the virtual machine to get the best performance without wasting resources. Perhaps this issue can be resolved only by tests or do you know another option?

  My answer: it's a different topic brother :-) It is different, because it is within a guest operating system (Windows in this case) and is no longer at the level of the ESXi. Suggest that post you another, possibly under Windows or vSphere too :-)

• SQL plan

  Hello
  on the 11g R2,.
  -Each sql plan is unique in a database? If Yes, how is identified and how to find it when you query SQL_ID?
  -Any request to find a DBA_HIST_SQL_PLAN sql plan?

• SQL Plan Management vs. cursors

  Hello
  
  We have recently implemented SQL Plan Management in our Production environment after two weeks of testing in development.
  
  Wouldn't you know, we proceeded to six questions which lasted much longer (, instead of less than a minute).
  
  The common denominator of these queries is that they are used as part of a loop of slider and make the use of bind variables. All other queries (and we talk about hundreds) was fine. The data has not changed for relevant queries.
  
  Is there a 'problem' with SPM and sliders/bind variable that anyone could have heard?
  
  Mark

  When you say SQL Plan Management, do you mean Plan SQL schedules?

  Baselines work by locking in a sql statement to a particular regime.

  The only problem that come to mind is that the referenced plan is not suited for all bind variable values.

  The first thing to look at would be the execution plans and they are in the base line, etc. - see DBMS_XPLAN. DISPLAY_AWR, also cross references to ash.
  Keep an eye on other features such as feedback of the cardinality.

  On 11.2.0.2, one thing to watch is a big SPM and recursive merge instructions involved. There is a patch, but it's usually pretty obvious if you are affected by this bug, for example
