Will there be any tools avialable to the on query performance tuning

Hello

How to tune a database query?
Suppose that there are basic query "select * from emp where empid = '1101' ';"

Y at - it all avilabale tools to suggest performance Tuning on a query?

How can I resolve this application, and what is the best approach on this?

Please share your ideas and thanks.

Oracle provides tools such as SQL Trace and TKPROF. For the information on a SQL query.

But basically, you should know how oracle works. You must be aware of the different access plans and know why they are being used.

You need to know when to use an index and when not to use a.

There are many more. Best thing for you would be to start reading the document.

  • The objects will not retain any color defined when the surrounding objects have their color changed

    Just Illustrator CC 19.0.0 was downloaded to me. When I place a line and then set its color, close objects can also have their color changed. This includes the items in the file of until I added the line, not on the same map-art objects. It is not universal, nor is it compatible. Objects already in the file are perhaps there for months, but a change is close will change their.

    The Illustrator files can still be an earlier version, and there were a number of illustrations that had black lines and text to white turned a few months back. As these illustrations are for a book, being unable to guarantee that the colors will stay together long enough to complete the illustration and export it tends to make unusable Illustrator for tasks of editions. I hope that InDesign and Photoshop do not have the same questions!

    nwjh,

    You must update to 19.1 (or 19.1.1 for Windows) or 19.2 (lattethe has some problems, then you can start with the former).

    If 19.1 (or 19.2) does not appear, disconnect and then reconnect the creative cloud application. After that, the 19.1 update must be visible in the creative application of Cloud.

  • The BLASTP_ALIGN query performance decreases as increases the size table Ref?

    Newbie here.

    I'm using Oracle 11.2.0.3.

    I am currently running and a loop through the cursor according to who uses the tool BLASTP_ALIGN from Oracle:

    FOR MyALIGN_TAB IN

    (

    Select a.query_string, H.AA_SEQUENCE target_string, t_seq_id, pct_identity, alignment_length, incompatibilities, positive, gap_openings, gap_list, q_seq_start, q_frame, q_seq_end, t_seq_start, t_seq_end, t_frame, score, wait

    from (select t_seq_id, pct_identity, alignment_length, incompatibilities, positive, gap_openings, gap_list, q_seq_start, q_frame, q_seq_end, t_seq_start, t_seq_end, t_frame, score, wait

    table (BLASTP_ALIGN ((p_INPUT_SEQUENCE SELECT query_string FROM DUAL),

    CURSOR (Select GB_ACCESSION, AA_SEQUENCE from HUMAN_DB1. HUMAN_PROTEINS),

    1-1, 0, 0, 'PAM30',. 1, 10, 1, 2, 0, 0)

    )

    ),

    (SELECT p_INPUT_SEQUENCE FROM DUAL Query_string).

    HUMAN_DB1. HUMAN_PROTEINS H

    WHERE UPPER (t_seq_id) = UPPER (H.gb_accession) and gap_openings = 0

    )

    LOOP


    This initial query works relatively well (about 2 seconds) on a table target of approximately 20,000 documents (reproduced above, as the HUAMN_DB1. Table HUMAN_PROTEINS. However, if I had to choose a selected target table that contains approximately 170 000 records, the query performance are significantly reduced in about 45 seconds. The two tables have identical ratings.


    I was wondering if there are ways to improve the performance of BLASTP_ALIGN on large tables? There only seems to be a lot of documentation on BLASTP_ALIGN. I could find this (http://docs.oracle.com/cd/B19306_01/datamine.102/b14340/blast.htm), but it wasn't that useful.


    Any ideas would be greatly appreciated.



    In case one is interested... it looked like the AA_SEQUENCE column in the following slider: SLIDER (Select GB_ACCESSION, AA_SEQUENCE from HUMAN_DB1. HUMAN_PROTEINS) was a CLOB field. In my second target, my column correspodoning table was VARCHAR2. One hypothesis is that BLASTP_ALIGN made a VARCHAR2-> CLOB conversion internally. I changed the table to have a CLOB column and with success against BLASTP_ALIGN 170 000 documents about 8 seconds (not much, but better than 45).

    I will mark it as answered.

  • Will there be any attempt to ADOBE to mitigate the "FLASH Update", twice a week, on all browsers, on all platforms?

    in my house, we run 3 win laptops, Win 2 tablets, 2 desktop computers Win, 2 SmartPhones Win, an iPad and an iPhone (as well as 2 Linux boxes).

    Now, you might say, OH, right there is your problem - I agree, this IS my problem.

    I wish I didn't have to run all of these machines, and 3 or 4 different browsers EACH requires different FLASH implementations--but, please, don't bother to argue this case.

    However, if FLASH needs updated, I have to spend more than an hour, sometimes for days at a time, just to get current FLASH!

    Part of this issue is that update 3 or 4 steps (in office), you must monitor - this seems very inefficient. (I am aware of the security implications)

    The situation is really impossible and considering FLASH is uninstalled on all systems, just to remove the headache - and costs (my time > potentially $100 / week X 52 weeks = eek!... for FLASH, really?)

    For comparison - my windows machines of updated (daily, or more) the operating system, applications, updates of malware, etc., without having to restart automatically in the background.

    What should do?

    Hello

    We anticipate to releases once a month.  Cases where we push several updates in a single week (or month) are made because a security hole has been found.  Our top priority is keeping our clients safe course.  We are working around the clock (and most weekends and holidays) to make sure get out us a fix to our customers as soon as POSSIBLE when such problems occur.  We know keeping up-to-date is difficult but you have a few options to choose from that will relieve the pain.

    My first recommendation would be to select "Allow Adobe to install updates (recommended)" in the Advanced tab of the control panel Flash Player.  Alternatively, you can also choose this option during the installation of Flash Player.

    Once selected, all your machines and browsers get more updates silently installed without any user interaction within 24 hours of an update made available.  There will be a few updates (usually quarterly) you will see a notification dialog box appear. They occur generally when a new major version is made available.  You can choose either manually install via this dialog box, or you can simply reject this dialogue and we will silently update you within 45 days.

    You can also switch your browser to Google Chrome, in which case Flash Player is built in.  No need to update, Google does it for you when they push their automatic updates.  Chrome is available for Mac, Win, Linux and of course, ChromeOS.

    If you have Windows 8, you can use Internet Explorer.  Flash Player for IE is integrated into Windows 8 and customers receive updates using the standard Windows Update service.

    On Linux, I recommend once again using Google Chrome.  If you need the NPAPI plugin, then I use one of the services of the distribution update and install Flash like this.

    Thank you

  • Will there be any problem of reactivation after the XP system restore?

    I just do a system restore (if out-of-the-box original factory of the machine) to a disk image.  After starting in Windows XP Pro SP2 I have entered configuration information initial requested as well as (as requested) Windows product key, but I jumped the (reactivation) activation step for now.  The motherboard has been replaced a year ago and I added RAM.  I all provided with the machine when you purchase including an OEM Windows XP SP2 "Recovery disc".  Will I have problems trying to activate/reactivate Windows or do I have to call Microsoft customer service to begin with.  Any advice or suggestions would be greatly appreciated.  Thank you!

    If the replacement motherboard was provided by Dell and Windows XP is as you mentioned a Dell OEM Dell recovery disk is required to provide support by Dell with Microsoft license agreement. If the computer is still in warranty, then support should be free.

    Activation should not be a problem as long as the product key belongs to the OEM recovery disk.

  • Will there be proactive with moderation after the 10 June 7 to upgrade?

    This is my first post on this topic (or any other) Oracle Forum.

    I want to know if my messages and responses here will be immediately available for others to view, or they will be subject to a delay caused by the need for a "moderator" approve my presentation.

    I looked at the FAQ for this forum, and I understand that it is subject to moderation after the fact (which is understandable and good).

    Thank you!

    Breck

    Addendum: When I posted this question, a message appears saying that there is a "slight delay" before she was visible... but the delay was very short. She says some kind of automatic process of moderation before the fact, or he says there is a huge room full of human moderators responding with wonderfully inhuman speed?

  • Any tool for debugging the server data sent

    Hello

    I sent a swf file to the Tomcat server.
    On the contribution to opt for this swf file, I expect an XML response from the server.
    Under debugging, when I used Mozilla Firebug to see the response XML generated from the server, I am disappointed
    as it does not show anything, except

    Content-Type: application/x-shockwave-flash

    Its not at all helpful for me, could someone let me know is there any other tool that would be useful, as in this case.


    Thank you.

    One word and one word:

    CHARLES!

    www.charlesproxy.com

    It is free to use, in 30-minute sessions, unless you pay for the license then it's unlimited use, and you could use wireshark is free.  But Charles puts all data in an easy to read format.  I don't go without it.  Look at my username, I don't pay for the software, but I paid for Charles (well... my employer did).

  • Will there be any vector drawing for Surface RT programs?

    I regularly use Adobe Illustrator. I would like to be able to work on the vector illustrations of a Tablet and then export it for heavier work as .ai or .eps file.

    Always do this; If you have friends, family, colleagues, etc., than do illustrative and CGI type work, the Pro model is the only tablet to get.  Believe it or not, the Pro is the tablet to cost lowest in its class compared to other windows tablets on the market and they are using the ATOM processor, which is inferior to the NVIDIA Tegra 3 located in the RT.

    Save your money and get the Pro model and the type of key keyboard/cover and mouse Microsoft Bluetooth Wedge.  The model Pro with a digitizing Tablet and includes a stylus.  This is also in place with what you want to do.

    Get an external DVD drive is not a bad idea either if you have a software that comes on disc.  These tablets can handle most of the models out there and if you know someone who has one, you can borrow to install these programs.

    A handful of 64 GB micro-SDHC card cards also will be useful as well.

    Plan before you buy and you can save yourself a big headache later.  The Pro model is worth over the long term.
