  Degree: Degree of parallelism. The default for the level is set to NULL. The default value can be changed using the SET_PARAM procedure. NULL means use the default value of the table specified by the LEVEL clause in the CREATE TABLE or ALTER TABLE statement. Use the constant DBMS_STATS. DEFAULT_DEGREE to specify the default value based on the initialization parameters. The AUTO_DEGREE value determines the degree of parallelism automatically. It's 1 (series performance) or DEFAULT_DEGREE (the default value of the system will depend on the number of processors and initialization parameters) according to the size of the object

• degree of parallelism and the number of files in the tablespace

  Hello
  
  I'm trying to find the relationship between the number of files in a tablespace and the degree of parallelism. because of the number of files in a tablespace effect dop in parallel query. because if several files are in the tablespace/o of the system has increased and the system became more feverable for a query parallel.
  
  But I looked in the dop formulas I can't find any settings that specify how the file is there in a tablespace. Please give me the formula for calculting dop in oracle.
  
  
  concerning
  Nick

  Hi Nick,

  It is not easy to determine the optimum degree of parallelism for the tasks of the Oracle.

  Oracle says that the best degree of parallelism for a query is based on several factors. These factors are presented in order of importance:

  -The number of processors on the server.

  -The number of physical disks located in the tables.

  -For parallelization of the partition, the number of partitions that will be available, based on the size of partition (if any).

  I can't find any settings that specify how the file is there in a tablespace.

  This is the number of physical spindles that matters, is not at the level of the tablespace.

  If I have diploma = 8, cpu_count = 8 and data are on 8 discs, there is no pretense.

  It's one of the problems with big great drives today, too few concurrency...

  I hope this helps...

  Start Firefox in Firefox to solve the issues in Safe Mode to check if one of your modules is causing your problem (switch to the DEFAULT theme: Tools > Modules > themes).

• IBM Thinkpad message: 'this machine can run faster with the USB 2.0 hub.

  Original title: Thinkpad USB 2.0 Hub.

  Hello:

  I have an IBM Thinkpad T-21 which is under Ubuntu & Windows xp.  I primarily use Windows XP.  The pop-up that keeps occurring is "this machine can run faster with the USB 2.0 hub.  Can you tell me how to upgrade my USB 2.0 Hub?  Would like to know because I can't sync my Android phone with my computer until I do it. Thank you.

  Are you sure you copied this error message properly?  In other words, he says that the hub could perform better if connected to a USB 2.0 port?  As far as I can determine that the T21 is not come with a USB 2.0 port, even if you connect a USB 2.0 device (for example a hub), the unit will only race as fast as the port allows it.

  What is the brand and model of your terminal?

  It is possible that the message means the opposite (i.e., your computer has a USB 2.0 port, but the hub is only a USB 1.1 device).

  USB 2.0 was introduced in 2001, so if you bought your computer before 2001, it is likely that you use USB 1.1 or 1.0.

  Open the Device Manager (start > run > devmgmt.msc > OK)
  Expand the category of 'USB Bus controllers'.
  If you see the "Enhanced" work for one or more of the listed devices, you have a USB 2.0 port.  If you do not see "Enhanced", you have USB 1.1.

  

  If the problem is that the USB port on the computer is not 2.0, so your only solution is to buy a USB 2.0 PC Card adapter.  Example and example 2
  If the problem is that the hub is not 2.0, then you will need to buy a new hub.

• SQL - degree Maximum parallelism

  Hello

  What is the common practice of the Dell Wyse vWorkspace point of view about this setting SQL? It could boost the performance that I understand.

  More information here > support.microsoft.com/.../2806535

  "The configuration of Microsoft SQL Server option degree of parallelism (MAXDOP) control the number of processors used in a parallel plan for executing a query. This option determines the it resources and wire that are used to query plan operators who do the work in parallel. »

  Hi Maarten,

  MAXDOP value 0 (which I believe is default) works for most people.

• Script to run Python with EEM on Nexus 9K

  Hello!

  I am trying to run the example provided in the following link for "Running Scripts with Embedded Event Manager":

  http://www.Cisco.com/c/en/us/TD/docs/switches/Datacenter/nexus9000/SW/6-...

  Here is my configuration of the Nexus 9 K switch EEM:

  NX9K-autonomous-Pod-1 # sh run EEM

  ! Command: show running-config EEM
  ! Time: Sat Nov 15 09:54:52 2014

  version 6.1 (2) I3 (1)
  Event Manager applet a1
  cli event corresponds to "display the clock.
  Action 1 cli python bootflash:pydate.py
  2 default event action
  Action 3 syslog msg I like EEM

  And here is an example of work of pydate.py that I grabbed from GitHub:

  GitHub Repo: https://github.com/haya14busa/pydate/blob/master/pydate.py

  NX9K-autonomous-Pod-1 # python bootflash:pydate.py
  DATETIME = 2014-11-15 09:47:03
  TIMESTAMP = 1416044823
  DateTime: 2014-11-15 09:47:03-> TimeStamp: 1416044823
  TimeStamp: 1416044823-> DateTime: 2014-11-15 09:47:03
  NX9K-autonomous-Pod-1 #.

  Finally, here is what happens when I run the command 'See the clock' in an attempt to trigger the EEM applet:

  NX9K-autonomous-Pod-1 # sh clock
  09:54:58.746 UTC Saturday, November 15, 2014
  NX9K-autonomous-Pod-1 # 2014 Nov 15 09:54:58 NX9K-autonomous-Pod-1% VSHD-5-VSHD_SYSLOG_CONFIG_I: configured for the vty by admin on vsh.8883
  2014-15 Nov 09:54:58 NX9K-autonomous-Pod-1% VSHD-5-VSHD_SYSLOG_CONFIG_I: configured for the vty by admin on vsh.8894

  Any help is appreciated!

  The syslog message must come before the 'event' by default.  As for what the Python script prints, it won't happen when she is called to the EEM.  But you may like the Cisco.com article says, look at the log to make sure that the script ran.

• HP laserjet 1200 using windows7, wired to the printer with a USB to parallel adapter

  HP laserjet 1200 using windows7. My computer has USB ports, but no parallel port, if the computer is connected to the printer with a USB to parallel adapter. Sometimes works very well, sometimes States printer system as ready, but do not print. Reboot hardware and upon restarting, I got a page to print. Next attempt to print updates the document in cue, but is right there - no error message. Finally, after several reboots, I managed to do print (have no idea how), but now I had to print 20 pages one page at a time. It will print no more than one page, even if I have to print the 20. Next time I start the computer I don't know if the printer will print. Do you need to use the same USB port each time, or are USB to parallel unreliable maps?

  Hey renradd!

  Unfortunately, in addition to the adapters USB can be unreliable. Only a new printer, I don't know what it will provide you with a fix for this problem. You can try a different card if you have one, but if it still does not work, I would look for in a printer capable of supporting your computer.

  I hope this helps!

• Degree of parallelism

  Hello

  I like to read Oracle Performance Tuning Guide (11g R2, Chapter 11)

  When I was reading on fulltable scan it says that

  High degree of parallelism

  A high degree of parallelism for a table tilts the optimizer to full table scan on the beaches of analyses. Look at the column LEVEL in ALL_TABLES for the table to determine the degree of parallelism

  
  I did not understand this. When I questioned all_tables I see only the value 1 in the LEVEL column. Can you explain what values will be there in the level column and how it will force Full Table Scan.

  Thanks a lot for your help in advance.

  See you soon,.

• Run javascript with a taskflow input parameters

  With the help of PS4 11 g JDev
  
  I have a taskflow using javascript. When the taskflow was loaded, I need to execute a javascript function that uses my taskflow 2 input parameters.
  I don't really know how I can run javascript with my input parameters.
  
  A test, I added a commandButton control in my taskflow who will do the job:
  

  <af:commandButton id="btnRefresh" text="Open">
              <af:clientAttribute name="long" value="#{pageFlowScope.pLong}"/> 
              <af:clientAttribute name="lat" value="#{pageFlowScope.pLat}"/> 
              <af:clientListener method="doNavigate" type="click"/>

  How can I do the same thing when the taskflow charge instead of having to press the button.

  Please find attached examples based on your use cases:

• Debug a tuxedo that is running server with dbx

  Hi all
  
  I'm triying to debug a server running Tux with dbx, calling one of its services by using a Java client. I've read (Re: gdb - problem of debugging and Re: Service Tuxedo in C/C++ debugging but I can't solve my problem with them.) These are the steps I followed:

  Thank you
  Gabriel

  Hi Gabriel,

  don't know if this qualifies as a related smoking question and I'm a little lost in all these lines, but...

  ... When you attach dbx to a process, it will become annexed by dbx (normal behavior) and you start to go through the instructions (machine code) using 'step', but I would (probably) use "cont (inue)" instead giving control to the process rather (based on what you really want to)

  Good luck
