Several instructions exit in a method - good or bad practice

• Several instructions set-peer - failover behavior

  Hi all

  I would like to confirm the behavior of the use of several instructions of the command "set-peer" under a single sequence of crypto-map for failover to IPSEC tunnel. In particular, what happens when a peer that has been previously unavailable returns to service?

  For example:

  I have two sites; Site 1 and Site 2 have two routers. All are connected by a routed cloud.

  Routers at each site have the following crypto card configured:

  Site1 - the two router A and router b:

  10 encryption ipsec-isakmp crypto map

  defined by peer RouterD
  defined peer RouterC

  Set transform-set 3desMd5
  match address 101

  Site2 - router-C and router D:

  10 encryption ipsec-isakmp crypto map
  defined peer RouterA

  defined peer RouterB

  Set transform-set 3desMd5
  match address 101

  HSRP is used on the side LAN between two routers on each site to prefer the router A and router C respectively as the active device.

  According to the Cisco documentation:

  "you can specify several counterparts by repeating this command (set-peer). The peer who has in fact, packets are sent to is determined by the last counterpart who heard the router (received traffic or a request for negotiation of) for a given stream. If the attempt fails and the first pair, Internet Key Exchange (IKE) tries the next peer on the crypto card list '.

  http://www.Cisco.com/en/us/docs/iOS/Security/command/reference/sec_s2.html#wp1046908

  If RouterA has an IPSEC tunnel to routerD... and router D fails, a tunnel is built between routerA and routerC. When the router D is backup... traffic switches to D from router to router A?

  What sequence of events would be the tunnel does not switch back once the main router has recovered from a failure?

  Thanks in advance.

  OK, that explains the behavior. When the router D returns, he becomes the main HSRP, traffic at the start of site 2 will use router D as point to exist; Router D paraphera session with A router ipsec. It looks like back switch for router D, but it's just because the initial D router to the router ipsec session has once he returns.

• several instructions box in where clause

  Hello

  I'm trying to create report filters using substitution variables in a case statement in a where clause clause. I have several instructions box running on the same column. I don't really know how to write it. Here's what I have so far but I know I'm going in the wrong direction.

  where

  i.compute_zone =

  When: P14_zone is NOT NULL

  then: P14_zone

  of other i.compute_zone

  How get the desired results of your data depends on the desired results and your data.  What do you do?  (I can't tell just by looking at the aat code that do not do).  After CREATE TABLE and INSERT statements for some sample data and a couple of sets of parameters (variables such as p14_zone) and the exact results that your choices in each set of parameters, given the same sample data.

  Check out the Forum FAQ: Re: 2. How can I ask a question on the forums?

  CASE expressions are generally not useful in a WHERE clause.  CASE expressions are a convenient way to IF-THEN-ELSE logic of the places where you can't do anything other than (the SELECT clause), but WHERE the clauses allow IF-THEN-ELSE logic in any case

  Maybe you want something like

  WHERE MERGE (: p14_zone,: p14_zone_2,: p14_zone_3,: p14_zone_4) IS NULL

  OR IN i.compute_zone (: p14_zone,: p14_zone_2,: p14_zone_3,: p14_zone_4)

  It returns TRUE if all 4 parameters are set to NULL.  If 1 or more of them are not NULL, then it will return TRUE if i.compute_zone is equal to one of them.

• Re-organization of database every week, it is good or bad?

  We use windows 2003 server and oracle 10.2.0.4, having two databases with 38 GB and another 72 GB. And the recommendation of the application team suggested to the reorganization of the database for each week. So, I want to know wheather do re-organization of complete database for each week is good or bad.

  Uwe Hesse wrote:
  It's bad. No sophisticated response required here. No DBA (Oracle) is supposed to do a "database reorganization' - whatever that means in detail - once a week.

  And if it is indeed a requirement of the team of apps: they built a very bad application :-)

  Uwe,

  I know you have read this before, but for reasons of the constant stream of the beginners

  I remember once more the seller make a ground for its product, kept talking about SQL Server. We informed that we were an Oracle shop. He said (and I quote): "we do not recommend running on Oracle, because we found that the Oracle can't handle more than 5 concurrent connections.

  I started my career 30 years ago as a developer. I am constantly amazed at the current generation of developers who seem to not only know nothing about the technology with which they work, but do not yet seem a curiosity about this. They give without thinking at all made to design anything.

  * I predict this thread will be sleeping in the next 48 hours, but 3 years from now, someone will record this with the forum, do some research on... on what? ... and revive this thread with a useless comment as their very first post.

  Kind regards

• Is the indicator parallel use / * + PARALLEL * / good or bad?

  Hello
  
  I am facing problem in the use of / * + PARALLEL * / hint in SQL Query took his time to run.
  
  Parallel Hint degrades performance?
  
  The FCT_TABLE Table is to have clause PARALLEL (DEGREE by DEFAULT DEFAULT INSTANCES).
  
  We use the suspicion parallel as SELECT / * + PARALLEL (FCT_TABLE 2)
  
  Any help will be necessary for me.
  
  Thanks and greetings

  Re: Using parallel Hint / * + PARALLEL * / good or bad?

  Bad news. (in production systems)

  Why? You, when you code this SQL statement with this point in development, have absolutely no idea of what the production will be like in a month. No idea what data will be. What another charging process will run. Or what will be the version of Oracle and hardware will look like.

  Yet, by coding this suspicion in the production of SQL, you claim you know. And not only that, you claim that you are in a position higher than the CBO to make an informed decision on whether to run SQL in parallel. You declare that production DBA knows his work and how to improve performance, and you have decided for them that the SQL should be run in parallel.

  Be very careful with advice in the code that lands in the production. Generally these efforts will simply cause more problems to solve problems.

  So why the parallel indicator then exist if it is so "+ bad +"?

  Very rarely (if ever) there are absolutes in software engineering. And there are exceptions where this indication can be extremely useful. But it's like a hammer in a Toolbox. You use it on the odd nail. You don't use every day to drive screws because the screwdriver is "+ hard +" to use.

• Several instructions if in conditional actions?

  Hello

  I have a single button on a slide.  Whenever the user clicks on it, a legend of additional text should be.  My original idea was to hide all captions, create a variable to keep track of how many times the user has clicked the button and when the button was clicked, check to see how many times it has been clicked and present the appropriate caption.  This approach would require multiple if statements because according to many times the button has been clicked, a different legend would have shown.

  After my research is preliminary, it was not possible in 2012.

  Someone at - it ideas?

  You cannot nest the IF, but you can achieve this with several decisions. You do not have to nest IF s to achieve this goal, although having a function BOX would make it easier (you can do that with JS). Here is a much simpler application with advanced actions:

• Qosmio X 770 - 11 c - good or bad experience?

  As a fan of Toshiba products (after my two PC Toshiba: M200, Satellite A200-1DS protégé), decided by a performance plus one.

  So I bought Toshiba Qosmio X 770 - 11 c, I was satisfied with the performance, I use matlab and 3dsmax.
  Then, after 7 months, I started seeing blue screens;

  I thought that it was perhaps with window 8 that the problems will be solved, unfortunately not...
  Call Toshiba, they fixed it (when I received it, indicating windows... blue screen again...)

  so I don't know what they fixed...!)
  Calling again because several times, finally after 3 and a half months they send UPS to fix it... up to now my PC is to toshiba repair...

  For me, it's a good chance with toshiba: I bought my PC... I've used it for 7 months... then... I'm on standby... :(

  I think that this will be my last PC Toshiba...
  Unfortunately, I loved their products before, I'm looking now for Lenovo, anyone has an idea on the performance of the pc. ?

  Sorry to read all this. The Qosmio series is Toshiba's best multimedia machine, but it was always too expensive for me so I m user of Satellite P series. I always use my Satellite P500 in hope Toshiba will again offer a large series of P again. I love the 18.4 screen.

  I put t know which BSODS have you noticed (error code) and what can be the reason. Have you tried to reinstall the recovery image and again test the functionality with the factory settings?

  I rally hope you will get your Qosmio soon and everything will be OK again.

• LabVIEW FPGA. Good modular coding practices.

  Hello

  Installation program:

  I have controls in the top vi FPGA communicates the host settings to the FPGA. I also have a sub - vi to generate output based on these settings. I placed the last part in a subvi since I want to reuse the code for several generators.

  Now to the question:

  If you want a sub - vi to run for always on the FPGA would you put you outside while loop within the subvi or in the top vi surrounding the sub - vi?

  First I always placed the while loop inside the subvi to have a cleaner top-vi. Now, I realized that it's probably a bad idea since I can no longer update the settings for the sub - vi because top-vi settings controls are not placed in a while loop. In the top vi I could just read another infinite loop controls the settings and save them in a global variable, only then I read in the sub - vi, but it would force the various sub - vi use the same global variable (and therefore the same settings). Is there a solution to this problem or should I always see just my sub - vi to be used in a loop to outter rather than having the loop in the sub - vi himself?

  For very simple applications, put the while loop in the first level VI will allow you to read/write controls/indicators according to the needs that may be the least amount of code. However, as your design becomes more complex, you really want to modularize and use an approach focused more on the events.

  I'll interpret your application as a processing loop main (i.e. under - reusable VI) with a secondary event loop that monitors updates to the host and RECONFIGURES the system. If this is the case, I would follow the other model you mentioned where I would separate the code into two separate processes (screws) that run independently. To the next level, you can build VI - Defined FIFO, memories or registers which then connect to each of these processes of 'connect' together so that they can communicate. The event host code treatment will be abandoned in a loop on the chart of top level so you can read/write commands/indicators directly, but we hope that most of the code is inside the event processing under VI.
