  • An unexpected error occurred during the generation of the Volume License Installer

    I'm building a Volume of NI Developer Suite 2016 DS1 License Installer.  I created the master suite and the installer from the DVD device drivers successfully.

    However, when I try to create tools Xilinx DVD separated issued with the Game Developer on I get the error "an unexpected error occurred during the generation of the Volume License Installer '.

    There is no other information.

    Nobody knows what is this 'unexpected error' and how to work around.

    Just worked it out.  The DVD contains 2 sets of tools; 14.7 & 2014.4.  You must come down with each of them separately, you can't just select the top-level of the DVD folder as you do with all the other discs in the package.  Would be useful if the error to a little more explicit.

    Found new hardware wizard runs, but after scanning stops the disc from the manufacturer with the message ' year error occurred during the installation of the device.»  The required section was not found in the INF"

    The export is only if you have installed Exchange or Outlook.  Copy the entire repertoire of dbx files to the Win7 computer desktop and make sure that the files are not read-only.  Then, in WLM use file | Import | Messages and point to this directory.

  • Microsoft 1.0.3001.0 security scanner will not complete scan

    I ran MS Safty Scanner several times. Fast parse does not return anything. The full scan checks the 1.6 million files and shows 42 infected files. The analysis ends but crashes it after completion and view the results file or fix anything. I ran in regular as well as several times safe mode. How can I fill this scan?

    You should check your version number of the Scanner.  The Safety Scanner is only good for 10 days after that it is downloaded, so a course on the site of Microsoft Safety Scanner download displays Versions of these files on the Version tab, when checking the properties for the msert.exe by right-clicking on it:

    32-bit: 1.115.1003.0

    64-bit: 1.115.1006.0

    Perhaps you need to redownload everything in making sure get you only the true Microsoft site.  I just ran a quick scan where the EICAR test file was found, removed and reported on the results of the scan.

    If you still have problems of deleting these 42 files, Microsoft security holders should be able to help:

    Yes, it's the way it happens. All the other stuff are load - computer office, drivers, anti-virus, etc.
    It takes longer is that you have a lot of programs that load with Windows.

    Win7 also much faster than XP load, anything.

  • Query not using Full Scan Index

    Hello world

    I'm on 11.2.0.3.0 AIX 6.1.

    There is a query such as:

    Select: sys_b_0 | Count (distinct (column_name)) table;

    that goes for the analysis full table. The column was values separate only 104 with not NULL values. To save memory buffer gets, I created an index on the table with the column used in the query (i.e. whose distinct values are recovered).

    The problem is that even after the creation of indexes and force the flag index that it does not use the full scan of the index. The provided indication is correct in syntax and was the only clue in the query, so there is no question of conflicts with others.

    Can anyone suggest me what I might be missing?

    Thank you

    It seems to me that if print_branch_code is defined as nullable in the table. If this is the case, the optimizer goes for a sweep of index, even if there is no real NULL values

  • Why the optimizer ignores Index Fast full Scan when much lower cost?

    Summary (tracking details below) - to improve the performance of a query on more than one table, I created an index on a table that included all the columns referenced in the query. With the new index in place the optimizer is still choosing a full Table Scan on an Index fast full scan. However, by removing the one query tables I reach the point where the optimizer suddenly use the Index Fast Full Scan on this table. And 'Yes', it's a lot cheaper than the full Table Scan it used before. By getting a test case, I was able to get the motion down to 4 tables with the optimizer still ignoring the index and table of 3, it will use the index.

    So why the optimizer not chooses the Index Fast Full Scan, if it is obvious that it is so much cheaper than a full Table Scan? And why the deletion of a table changes how the optimizer - I don't think that there is a problem with the number of join permutations (see below). The application is so simple that I can do, while remaining true to the original SQL application, and it still shows this reversal in the choice of access path. I can run the queries one after another, and he always uses a full Table Scan for the original query and Index fast full scan for the query that is modified with a table less.

    Watching trace 10053 output for the two motions, I can see that for the original query 4 table costs alone way of ACCESS of TABLE UNIQUE section a full Table Scan. But for the modified query with a table less, the table now has a cost for an Index fast full scan also. And the end of the join cost 10053 does not end with a message about exceeding the maximum number of permutations. So why the optimizer does not cost the IFFS for the first query, when it does for the second, nearly identical query?

    This is potentially a problem to do with OUTER joins, but why? The joins between the tables do not change when the single extra table is deleted.

    It's on 10.2.0.5 on Linux (Oracle Enterprise Linux). I did not define special settings I know. I see the same behavior on 10.2.0.4 32-bit on Windows (XP).

    Thank you

    DETAILS
    I've reproduced the entire scenario via SQL scripts to create and populate the tables against which I can then run the queries. I've deliberately padded table so that the length of the average line of data generated is similar to that of the actual data. In this way the statistics should be similar on the number of blocks and so forth.
