Handling Too-Long Or Too-Short Transactions Because MyISAM tables do not support, you might not have paid much attention to the configuration option and the and statements. These keywords are important to allow multiple sessions to read and write InnoDB tables concurrently, providing substantial scalability benefits in write-heavy workloads. While a transaction is open, the system keeps a snapshot of the data as seen at the beginning of the transaction, which can cause substantial overhead if the system inserts, updates, and deletes millions of rows while a stray transaction keeps running.
Thus, take care to avoid transactions that run for too long. If you are using a session for interactive experiments, always (to finalize the changes) or (to undo the changes) when finished. Close down interactive sessions rather than leave them open for long periods, to avoid keeping transactions open for long periods by accident. Make sure that any error handlers in your application also incomplete changes or completed changes. is a relatively expensive operation, because, and operations are written to InnoDB tables prior to the, with the expectation that most changes are committed successfully and rollbacks are rare.
When experimenting with large volumes of data, avoid making changes to large numbers of rows and then rolling back those changes. When loading large volumes of data with a sequence of statements, periodically the results to avoid having transactions that last for hours. In typical load operations for data warehousing, if something goes wrong, you truncate the table (using ) and start over from the beginning rather than doing a. The preceding tips save memory and disk space that can be wasted during too-long transactions. When transactions are shorter than they should be, the problem is excessive I/O. With each, MySQL makes sure each change is safely recorded to disk, which involves some I/O.
For most operations on InnoDB tables, you should use the setting. From an efficiency perspective, this avoids unnecessary I/O when you issue large numbers of consecutive, or statements. From a safety perspective, this allows you to issue a statement to recover lost or garbled data if you make a mistake on the command line, or in an exception handler in your application. The time when is suitable for InnoDB tables is when running a sequence of queries for generating reports or analyzing statistics. In this situation, there is no I/O penalty related to or, and InnoDB can. If you make a series of related changes, finalize all the changes at once with a single at the end.
For example, if you insert related pieces of information into several tables, do a single after making all the changes. Or if you run many consecutive statements, do a single after all the data is loaded; if you are doing millions of statements, perhaps split up the huge transaction by issuing a every ten thousand or hundred thousand records, so the transaction does not grow too large. Remember that even a statement opens a transaction, so after running some report or debugging queries in an interactive session, either issue a or close the session. Handling Deadlocks You might see warning messages referring to “ deadlocks” in the MySQL error log, or the output of.
Despite the scary-sounding name, a is not a serious issue for InnoDB tables, and often does not require any corrective action. When two transactions start modifying multiple tables, accessing the tables in a different order, they can reach a state where each transaction is waiting for the other and neither can proceed. When is enabled (the default), MySQL immediately detects this condition and cancels the “ smaller” transaction, allowing the other to proceed. If deadlock detection is disabled using the configuration option, InnoDB relies on the setting to roll back transactions in case of a deadlock. Either way, your applications need error-handling logic to restart a transaction that is forcibly cancelled due to a deadlock. When you re-issue the same SQL statements as before, the original timing issue no longer applies. Either the other transaction has already finished and yours can proceed, or the other transaction is still in progress and your transaction waits until it finishes.
If deadlock warnings occur constantly, you might review the application code to reorder the SQL operations in a consistent way, or to shorten the transactions. You can test with the option enabled to see all deadlock warnings in the MySQL error log, rather than only the last warning in the output. For more information, see. Planning the Storage Layout To get the best performance from InnoDB tables, you can adjust a number of parameters related to storage layout.
When you convert MyISAM tables that are large, frequently accessed, and hold vital data, investigate and consider the and configuration options, and the of the statement. During your initial experiments, the most important setting is.
When this setting is enabled, which is the default, new InnoDB tables are implicitly created in tablespaces. In contrast with the InnoDB system tablespace, file-per-table tablespaces allow disk space to be reclaimed by the operating system when a table is truncated or dropped. File-per-table tablespaces also support and row formats and associated features such as table compression, efficient off-page storage for long variable-length columns, and large index prefixes. For more information, see. You can also store InnoDB tables in a shared general tablespace, which support multiple tables and all row formats.
For more information, see. Transferring Existing Data To transfer a large volume of data into an empty InnoDB table created as shown in the previous section, insert the rows with INSERT INTO innodbtable SELECT. FROM myisamtable ORDER BY primarykeycolumns. You can also create the indexes for the InnoDB table after inserting the data. Historically, creating new secondary indexes was a slow operation for InnoDB, but now you can create the indexes after the data is loaded with relatively little overhead from the index creation step. If you have UNIQUE constraints on secondary keys, you can speed up a table import by turning off the uniqueness checks temporarily during the import operation: SET uniquechecks=0.
Import operation. SET uniquechecks=1; For big tables, this saves disk I/O because InnoDB can use its to write secondary index records as a batch. Be certain that the data contains no duplicate keys. Permits but does not require storage engines to ignore duplicate keys. For better control over the insertion process, you can insert big tables in pieces: INSERT INTO newtable SELECT. FROM oldtable WHERE yourkey something AND yourkey.
Storage Requirements If you intend to make several temporary copies of your data in InnoDB tables during the conversion process, it is recommended that you create the tables in file-per-table tablespaces so that you can reclaim the disk space when you drop the tables. When the configuration option is enabled (the default), newly created InnoDB tables are implicitly created in file-per-table tablespaces. Whether you convert the MyISAM table directly or create a cloned InnoDB table, make sure that you have sufficient disk space to hold both the old and new tables during the process. InnoDB tables require more disk space than MyISAM tables. If an operation runs out of space, it starts a rollback, and that can take hours if it is disk-bound. For inserts, InnoDB uses the insert buffer to merge secondary index records to indexes in batches. That saves a lot of disk I/O.
For rollback, no such mechanism is used, and the rollback can take 30 times longer than the insertion. In the case of a runaway rollback, if you do not have valuable data in your database, it may be advisable to kill the database process rather than wait for millions of disk I/O operations to complete. For the complete procedure, see. Declare a PRIMARY KEY for each table.
Typically, it is the most important column that you refer to in WHERE clauses when looking up a single row. Declare the PRIMARY KEY clause in the original statement, rather than adding it later through an statement. Choose the column and its data type carefully. Prefer numeric columns over character or string ones.
Consider using an auto-increment column if there is not another stable, unique, non-null, numeric column to use. An auto-increment column is also a good choice if there is any doubt whether the value of the primary key column could ever change.
Changing the value of a primary key column is an expensive operation, possibly involving rearranging data within the table and within each secondary index. Consider adding a to any table that does not already have one. Use the smallest practical numeric type based on the maximum projected size of the table.
This can make each row slightly more compact, which can yield substantial space savings for large tables. The space savings are multiplied if the table has any, because the primary key value is repeated in each secondary index entry. In addition to reducing data size on disk, a small primary key also lets more data fit into the, speeding up all kinds of operations and improving concurrency. If the table already has a primary key on some longer column, such as a VARCHAR, consider adding a new unsigned AUTOINCREMENT column and switching the primary key to that, even if that column is not referenced in queries.
This design change can produce substantial space savings in the secondary indexes. You can designate the former primary key columns as UNIQUE NOT NULL to enforce the same constraints as the PRIMARY KEY clause, that is, to prevent duplicate or null values across all those columns.
If you spread related information across multiple tables, typically each table uses the same column for its primary key. For example, a personnel database might have several tables, each with a primary key of employee number. A sales database might have some tables with a primary key of customer number, and other tables with a primary key of order number. Because lookups using the primary key are very fast, you can construct efficient join queries for such tables. If you leave the PRIMARY KEY clause out entirely, MySQL creates an invisible one for you. It is a 6-byte value that might be longer than you need, thus wasting space. Because it is hidden, you cannot refer to it in queries.
Application Performance Considerations The reliability and scalability features of InnoDB require more disk storage than equivalent MyISAM tables. You might change the column and index definitions slightly, for better space utilization, reduced I/O and memory consumption when processing result sets, and better query optimization plans making efficient use of index lookups. If you do set up a numeric ID column for the primary key, use that value to cross-reference with related values in any other tables, particularly for queries. For example, rather than accepting a country name as input and doing queries searching for the same name, do one lookup to determine the country ID, then do other queries (or a single join query) to look up relevant information across several tables.
Rather than storing a customer or catalog item number as a string of digits, potentially using up several bytes, convert it to a numeric ID for storing and querying. A 4-byte unsigned column can index over 4 billion items (with the US meaning of billion: 1000 million). For the ranges of the different integer types, see.
Install Mysql Using Inno Setup Skin Rating: 3,7/5 9378reviews Lately I was told at work to create an installer for our new product. Till that moment I used to create exe installers with which has many advantages: it’s easy-to-use, powerfull and (the most important ? ) I used it so many times that creating a new installer is a matter of minutes. But this time I heard a big ‘no-no’ for an exe – it had to be msi. A reserve currency (or anchor currency) is a currency that is held in significant quantities by governments and institutions as part of their foreign exchange reserves. Install Mysql Using Inno Setup Unpacker. Inno Setup itself and additionally includes an option to install the Inno Script Studio. Inno Script Studio v.
Feature GUI Toolkit for Visual Basic v. Featured Inno Script free downloads and reviews. This installation was built with Inno Setup. I created a simple “Setup Project” in Visual Studio, played with it for a while and hoped that will work as expected. Well, it worked, but I was told it needed some customizations (graphics, custom dialogs, launching the installed application after install). After doing some googling I was able to do all those things by editing the setup project and modifying the output MSI with Orca.
But because every time I needed to create that installer for the new version I had to do some things (for example in Orca) manually – I really hated this solution. So I used google again and I found a really cool, freeware toolset called which does everything I needed. You just create a XML-like file describing the installer and the toolset creates the MSI for you. Our goal We will create here a simple MSI installer for our program (called Sample App). The installer will:. allow the user to select the installation directory. create a program folder in the Start-Programs menu.
show license agreement dialog. have customized graphics. give the user the option to launch our application after installing it.
install the application for all users One thing to note – there are two versions of WiX available – v2 and v3. As v3 is still in beta stage, I used v2 at the beginning. But then I tried using the beta and it occured to be simpler to use and so much more powerful that I haven’t returned to v2. So I recommend using the WiX 3 (as I will do in the examples below).
A tiny bit of theory The are some good WiX tutorials on the Internet that will give you more in-depth knowledge about WiX and MSI than this little article. I recommend reading for a start. Here I will just show you how to create your first MSI installer with WiX, without worrying about more advanced features and background details. First some basic concepts:. our application is a product. It’s identyfied by two unique GUIDs.
Filemaker Pro 13 Advanced Mac Ita Torrent. Product GUID changes every time you change the version of your app.
candle.exe SampleApp.wxs light.exe SampleApp.wixobj Play with it for a while, check if it installs the executable into the Program Files subdirectory, if you can uninstall the application (and if it’s actually removed). Application folder in Programs menu Ok, we installed our product, but the user has to manually navigate to its home directory to launch it. We really should create a folder in Programs menu. Here is how we do that. First we have to create a subfolder in Program Menu. Add the following Directory structure as a child of TARGETDIR directory tag: This would create a folder we wanted.
We have a new component responsible for creating this directory. Add it to our ‘Complete’ feature. We create also a dummy registry entry. This is required because without it light would complain about ICE38 error. This is a workaround ? We want our shortcut to have an icon. We can define it this way: This can be put before Feature tag. Now we have everything that’s needed to create a shortcut in ‘ProgramMenuDir’ folder.
To create it we to put this inside out File tag: Adding and customizing the UI WiX offers some predefined user interfaces. We will use InstallDir, which shows license agreement and allows the user to specify the installation directory. To add this interface place the following two lines (for example after Feature closing tag): While creating the installer we have to use the extension containing our UI. Use the following command. light.exe SampleApp.wixobj -ext WixUIExtension That was pretty simple, wasn’t it?
Now we can customize the interface a little bit. First we can provide the our own license. It should be in RTF format.
I assume the file is called OurLicense.rtf. You can also change the graphics (I really don’t think the default red skin looks good). To do so create two bitmaps. The first is for the welcome dialog. It’s size is 493×312 pixels, call the file dlgbmp.bmp.
The second image is the top banner visible on the rest of the dialogs. Its size is 493×58 pixels. Put it in bannrbmp.bmp file. Both bitmaps should be RLE compressed, cos this will reduce our output msi file size.
Now, that we have the necessary file prepared, we can customize the installer. Those three lines take care of it: You can put those 3 lines after UIRef tag. And voila, we customized our installer! Launching the application when setup ends Suppose we want to add a checkbox on the last installer dialog, something like “Launch Sample App when setup exits.” This is more tricky ‘cos we have to copy the default exit dialog and modify it. I’ve found a very useful describing the way to do it (the second method in “Conditionally launching the application after installation”). Follow the steps described in that article to add the checkbox we wanted. This works almost perfect.
However I advise to improve it a little bit. First we would like the checkbox to be checked by default.
To achieve this add the following property to our installer: The text next to the checkbox has a fixed application name. Replace ‘Sample App 1.0’ with ‘ProductName’ in MyExitDialog.wxs.
The WiX will put our application name automatically. The third annoying thing is that the ckeckbox is visible every time the installer finishes. If you run the installer for the second time and chose ‘Remove’ option, your application will be removed and the checkbox ‘Launch’ won’t make any sense – it should be hidden. So let’s hide it. Open MyExitDialog.wxs again and add the condition that will hide the checkbox: To make sure the action will not be executed after removing the application, edit the SampleApp.wxs adding the new launch condition: LAUNCHAPPONEXIT AND NOT (WixUIInstallMode = 'Remove') This does the trick.
To build the installer execute the following commands. candle.exe SampleApp.wxs MyExitDialog.wxs MyWixUIInstallDir.wxs light SampleApp.wixobj MyExitDialog.wixobj MyWixUIInstallDir.wixobj -out SampleApp.msi -ext WixUIExtension Minor installer improvements We can add some minor features to our installer:. installing the application for all users If you want to install your application for all users, not only the current one, this does the trick: 1. prerequisites Suppose your application requires Microsoft.NET Framework 2.0 to run. Add the following condition to check if it’s installed: = '2.0.50727'. installer privileges If your installed needs administrative right to install the software, add this condition: Privileged. product version Right now the product version is specified in SampleApp.wxs file and has to be changed manually when your product version changes.
I use a little Python script that reads the version from compiled executable and modifies wxs file. Moreover if the product version changed from the last time, it generates a new product GUID. If you wold like to write that script, here are the two functions that will be useful: import win32api import msilib import os.path def getversionnumber(file): if os.path.exists(file): info = win32api.GetFileVersionInfo(file, ' ') ms = info'FileVersionMS' ls = info'FileVersionLS' return win32api.HIWORD(ms), win32api.LOWORD(ms), win32api.HIWORD(ls), win32api.LOWORD(ls) def generatenew guid: return msilib.genuuid1:-1 Our final installer Here is the final version of the SampleApp.wxs file (remember that you need also MyExitDialog.wxs and MyWixUIInstallDir.wxs as described ). Privileged = '2.0.50727'LAUNCHAPPONEXIT AND NOT (WixUIInstallMode = 'Remove') 12 Responses. Asif October 14, 2008.
