• SQL tuning advisor recommnds to create the function SYS_OP_C2C function index

  I have a large table and an index on it. I use a tool to fill data, this simple tool submits the sql for Oracle DB and it does NOT index to use for requests. When I run the sql tuning advisor, he recommends to create additional indexes and use the SYS_OP_C2C function, which I don't want.
  
  When I run the query through sql plus picks it up in the index.
  Someone of you came, why its recommend that additional nonsense?
  
  create index abc.xxxx on this_table (SYS_OP_C2C ("this_column"));
  
  Thank you

  The internal Oracle SYS_OP_C2C function perform the conversion of a set of characters to another set of characters - C (haracterSet) 2 c (haracterSet). There are situations where you will see this conversion without explicit, as in this case command that should be a sign that the data types are not the same and the implicit conversion takes place and this could also be a problem from the point of view performance because it can disable the use of the index.

  Make sure you the characterset and nls set of all of the database and the tool are the same.
  Make sure that the data type of the column in the index is the same as the database.
  Confirm the ETL vendor for your database support and fixes, etc..

  Optimizer will only advise to use this function when the data type or the character set does not match.

• PL/SQL... avoiding the database

  Dear all,
  
  Maybe it's a weird question, but I want to run PL/SQL processes without writing them in the database. Let me explain...
  
  In the past, I've always used "CREATE OR REPLACE PROCEDURE... "to write PL/SQL code.
  
  However, with my current client data is "locked" and I don't have permissions to do this. Usually, this is not a problem, as almost everything I do can be managed with SQL scripts that I can call with SQL * more. No problem.
  
  But there are a few points where it would be very nice to set up a simple loop and repeatedly call some SQL commands (send a different filter/parameter each time clause). So my question is whether it is possible to write code PL/SQL 'temporary' in a SQL script, call this script (with SQL * more) and then to have this script without writing in the database?
  
  If so, then maybe someone knows a link or a howto that I can take a look at?
  
  Best regards and many thanks,
  Alan Searle

  They are called anonymous blocks. You can do it like that.

  DECLARE
        
  BEGIN
        
  END;
  /
  

  It can run directly within your window of sqlplus.

  Thank you

• What is this new SQL Beta - 1z1 - 071 - 2 SQL - Oracle Database SQL 12 c

  Hello

  It's confusing.

  This looks like a 2nd review SQL for Oracle 12 c.

  What is this new SQL Beta - 1z1 - 071 - 2 SQL - Oracle Database SQL 12 c

  Can someone explain.

  Roger

  OK - I guess I should have held off a few hours before my previous answer.  I just got an email in the Certification of Oracle program manager. Now, I have inside information.

  1Z0-071 is a SQL new test and the role it plays is between that of the review of databases SQL and SQL Expert.  Specifically, unlike review of databases SQL, passing it will give proof of the OCA for people who spend. I don't know more than that yet.  The review details page is not available and if the subjects are currently a grey area for me.  I'll probably create a blog on the review, if I can get a few details about it.

• SRM + SQL + 3rd party replication and suspend the DB

  Gentlemen

  What can the SRM to ensure customers a SQL VM running on (and replicated by) 3^rd party storage is applied consistently? The HP SRA has code that can invoke the suspension in the virtual machine? Or is there some kind of way scripted as part of SRM, that a quiesce DB in the virtual machine can be triggered in tandem with or just as a LUN replication occurs?

  I know that HP is responsible for the ASR - but in these situations, we sometimes get caught between vendors. Looking for experience "How have any other mission critical SQL resources protected using 3PAR and SRM".

  In other words:

  We are looking for assistance with a DR implementation for a specific application of SQL. The app is on virtual machines running on 3PAR storage. We bought all the necessary "3PAR suite application licenses" and then also have VMware SRM.

  We are more concerned than LUNS replicated DR on-site production (LUN will be virtual computers hosting SQL data storage I assume) will be fully SQL-compliant (i.e. better than crash-consistent), during replication.

  We have some experience with 3PAR replications - but to my knowledge have not yet worked with the application suites.

  Question - anyone can describe what role (if any) suites of applications 3PAR can have in correctly the suspension SQL running on a virtual machine that is on a LUN 3PAR? I don't know we can do this medium - seems that we will have to use RDM (or vVOls if they are compatible SRM) be properly suspended the DB. Is there a HP storage agent that can run on a VM SQL in order to coordinate with the table when the underlying LUN snapshots are performed?

  You are right. Consistency in the application will have to be managed at the level of the array. Some providers of table (I know NetApp specifically) offer the ability to place an agent on the VMS and this agent to use the table to ensure uniformity in the application, I'm not sure of HP.

  Another option that you might look at is vSphere replication. VR offers quiecing VSS (with JEREMIAH) in native mode.

  If you are looking for a specific response to the use of replication 3PAR application suites I suggest you post to a forum of HP. vVOLs are not yet compatible with SRM and I do not see how RDM you will get what you are looking for.

  Finally, how you deal with your post, I would say that you do not assume that only men participate in this forum.

• Performance problem on the SQL query that does not use the primary key index

  Hello!
  
  I have some performance issues on a single SQL query (Oracle 10 g).
  I could solve the problem by using the INDEX indicator, but I would like to know WHY this is happening.
  
  * Tables *.
  create table jobs)
  ID number (5) not null,
  name varchar2 (100),
  primary key constraint Job_PK (id)
  )
  /
  -Record count: 298
  
  create table Comp)
  integer ID not null,
  name varchar2 (100),
  primary key constraint Comp_PK (id)
  )
  /
  -Record count: 193
  
  -Relation m: n
  create table JobComp)
  integer ID not null,
  id_job integer not null,
  id_comp integer not null,
  primary key constraint JobComp_PK (id),
  unique key constraint JobComp_UK (id_job, id_comp),
  Constraint JobComp_FK_Job foreign key (id_job) refers to Job (id),
  Constraint JobComp_FK_Comp foreign key (id_comp) makes reference Comp (id)
  )
  /
  create index JobComp_IX_Comp on JobComp (Cod_Comp)
  /
  create index JobComp_IX_Job on JobComp (Cod_Job)
  /
  -Record count: 6431
  
  * Ask *.
  
  When I run this query, the execution plan shows the index using (JobComp_PK and JobComp_IX_Comp).
  No problem.
  
  Select JobComp.*
  of JobComp
  Join jobs
  on Job.id = JobComp.id_job
  where JobComp.id_comp = 134
  /
  -runs in 0.20 sec
  
  But when I add the field 'name' of the work table the plan uses full access table to the table of work
  
  Select JobComp.*, Job.name
  of JobComp
  Join jobs
  on Job.id = JobComp.id_job
  where JobComp.id_comp = 134
  /
  -runs in the 2.70 dry
  
  With the help of the index
  
  Select / * + INDEX (Job Job_PK) * /.
  JobComp.*, Job.name
  of JobComp
  Join jobs
  on Job.id = JobComp.id_job
  where JobComp.id_comp = 134
  /
  -runs in 0.20 sec
  
  * Doubt *.
  
  This behavior is correct?
  
  PS. : I tried to recalculate the statistics, but nothing changes:
  
  analyze the job calculation table statistics.
  /
  change the statistical calculation of index Job_PK reconstruction;
  /
  Start
  dbms_utility.analyze_schema (sys_context ('userenv', 'current_schema'), 'CALCULATE');
  end;
  /

  The execution time of the querys "without field name' and 'with the field name with suspicion" are equal.
  He has no problem caching, because I get the plans of the sequence different from the querys and repeated the performance. The result is always the same.

  I don't think that there is no problem with oracle crossing LOOP IMBRIQUEE to the HASH JOIN when you include the field name and this should be the expected behavior. But it seems that your WORKING table has a degree of parallelism set against what is causing the query to run in parallel (as JOB table is now available with full table scan, instead of indexed access earlier). It could be that the parallel execution is contributor to extra Runtime.
  (a) do you know why the degree of parallelism on the WORK table has been defined? Do you need it?

  You can see if the following query provides a better response time?

  select /*+ NOPARALLEL(JOB) */ JobComp.*, Job.Name
    from JobComp
    join Job
      on Job.id = JobComp.id_job
   where JobComp.id_comp = 134

  Depending on what you mean by "voice command", either:

  Settings / general / accessibility / VoiceOver / OFF, or

  Settings / Siri / OFF

  As for your use of the battery, you can check what app pulls most of its use in the settings / battery.  A new version of the app is sometimes problematic, not necessarily iOS or iPhone.  If you see a unusual % of use of a particular application, or force-to leave it removal/reinstalling it or remove it until an update comes.  If anything seems unusual, it might be a problematic installation of iOS, in which case, you could backup your iPhone and restore it:

• mail increases with the size of file and attached attachment

  The question:
  Mail with no attachment size is approximately 3, 17 KB (3,251 bytes)
  An email with an attachment 38.1 MB (38075102 bytes), where the attachment is
  27.8 MB (27820247 bytes) why this great email with attachment and is even greater
  When the attachment is larger? I've calculated 30% increase in the mail itself to size
  the size of the attachments. This causes problems with sending mail to an SMTP server with a size limit
  20 MB of not able to send a 19 MB file cause the post itself is even more important. It is only in

  Sending a binary file as an attachment increases its size by a third due to base64 encoding sending two 8-bit characters as three characters of 7-bit ASCII.

• Satellite R830-1GZ - CPU usage high (> 25%) and increase in the speed of the fan after reactivation

  Hi all

  The CPU usage of my laptop shoots upward to 25% (and beyond) and increases in fan speed considerably after waking up, but only when I use an external mouse (Microsoft Natural Wireless Laser Mouse 6000) - disconnect the mouse once it happened does not solve the problem, so I always have to restart my computer if I let go sleep with the connected mouse.

  I noticed that when this produces the system interrupts - delayed appeals procedure and Interrupt Service routine appears in the resource monitor > CPU > process and seems to explain the increase in the use of the processor.

  Any ideas on how to solve this problem would be most appreciated.

  I use a Toshiba Satellite R830 1GZ with Windows 7 (64-bit). This problem will not occur when I use the same mouse with another laptop (Dell with Windows XP).

  Thank you very much.
