Oracle MySQL 5.6 Developer

MySQL 5.6 boasts superior hurry | killexams.com real Questions and Pass4sure dumps

whereas the development world continues to be spellbound by using NoSQL revolutions, the decidedly SQL-based mostly MySQL hasn’t stood nevertheless. nowadays, Oracle announced the unlock of MySQL 5.6, which comprises a great number of speedups, and a brand fresh assume on the NoSQL model in line with Memcached.

Tomas Ulin, vice president of MySQL engineering at Oracle, mentioned that there are a number of most necessary optimizations covered in 5.6. Queries should soundless sprint quicker for a lot of kinds of workloads, as an instance.

Ulin mentioned there may soundless be “stronger question execution instances and more advantageous diagnostics. they beget sub-query optimizations. We’ve rewritten how they address sub-queries. There’s in reality no fresh features there, simply quicker execution.”

these optimizations prolong down into InnoDB, as neatly, the situation the MySQL team has brought index condition pushdown optimizations. These optimizations enable the MySQL server to hand off some records circumstances to the storage engine, allowing stated engine to in shape circumstances earlier than reading in a complete row of statistics. the employ of these optimizations, InnoDB (MySQL’s default storage engine) shouldn’t beget to conclude as many reads when doing a row retrieval.

in other places during this free up, Ulin mentioned loads of labor has been carried out to boost transparency when troubleshooting database issues. The team at Oracle, he spoke of, has added optimized traces and question execution plans. InnoDB has furthermore been optimized, and thru this work, MySQL 5.6 can aid up to forty eight cores.

“we will now address a considerable deal more concurrent load devoid of getting congestion, which means they are able to scale out with extra cores,” spoke of Ulin. “we beget linear scalability to 48 cores on both read and write masses. The transactional throughput has stronger thrice in the scale-out status of affairs. What this actually means is that MySQL can now utilize the simultaneous hardware.”

InnoDB has additionally brought full textual content search capabilities.

most likely essentially the most enjoyable fresh addition to MySQL 5.6 is the inclusion of NoSQL-like capabilities, created throughout the addition of Memcached. “We introduced a yr in the past they beget been adding the Memcached API to access and update information in InnoDB,” said Ulin. “we will be a fraction of the better of both worlds within the SQL/NoSQL discussion. They suppose they can create it much more convenient to profit the benefits of NoSQL-category access. They proffer you a versatile, powerful language to sprint through your data. We’ve observed as much as nine-times advancements the usage of the NoSQL interface.”


publication explores Oracle, MySQL question strategies | killexams.com real Questions and Pass4sure dumps

Michael McLaughlin’s Oracle 11g & MySQL 5.6 Developer lead  features out several techniques Oracle builders can create their lives more convenient. One chapter specializes in SQL querying and singles out some time-saving, speed-gaining hints, infatuation the usage of keywords and utility development tools.

SearchOracle.com currently caught up with McLaughlin to ascertain greater about how knowledgeable employ of Oracle queries can improvement developers.

What are some common mistakes and complications that builders countenance when querying?

Michael McLaughlin: medium mistake are design considerations more than they're syntax error. SQL design considerations create queries that return inconsistent, mistaken or inefficient results. discrepant or incorrect outcomes generally assume situation as a result of be a fraction of circumstances fail to resolve a relationship or where clause circumstances fail to filter rows accurately.

Inefficient queries often matter on inefficient joins that may furthermore disable or employ needless indexes, or they may furthermore matter on correlated queries, the situation the be fraction of commentary matches non-entertaining column values. A fix to the non-uniquely matched correlated queries is standard, since you employ a glance up operator just infatuation the IN, =ANY or =SOME, total of which return results sooner for non-uniquely matched column values.

What are the benefits of key phrase employ when querying?

McLaughlin: key phrases cowl a few roles in SQL and are efficient once they wait on developers visualize statistics or SQL syntax. key phrases equivalent to inner, LEFT, appropriate and gross be fraction of qualify the connection among tables and generally aid builders visualize which table gives what facts. for example, an inner be a fraction of or be a fraction of is the intersection of tables. It requires that you just determine the columns that assist the be a fraction of operation automatically following the observation. In ANSI 92, the where clause most efficient includes statements that filter the return set on non-be a fraction of conditions. The older ANSI 89 vogue separates tables with commas and lets be a fraction of statements appear any situation in the the situation clause. The the situation clause then incorporates be fraction of statements and filtering statements.

LEFT, birthright and entire unite statements intend you can role outer joins. A LEFT be a fraction of takes everything on the left plus the intersection, which is commonly clearer than the older Oracle option of the usage of "+" symbols. it truly is as a result of LEFT or appropriate means that you can visualize the situation the non-intersection data is determined. nevertheless, a "+" is build on the facet where there might not be any records backyard of the intersection. It only makes feel to a few builders in case you interpret set thought and mechanics and that makes it greater mathematical than valuable.

might you interpret the importance of table aliases and why builders should employ them?

McLaughlin: table aliases, infatuation desk names, disambiguate identical-named columns when they're returned with the aid of a query. desk aliases often curtail the typing of long, descriptive names. they may be gauge if you befall to unite copies of the identical tables since the table alias allows dissimilar copies of tables in a question.

What are the benefits and disadvantages of the employ of application development tools in comparison with the employ of the command-line interface?

McLaughlin: There are extra advantages to using utility edifice materiel than there are drawbacks. they are tremendous to prototype queries as well as insert, update and delete statements in isolation. They furthermore let you package and sprint script files. sooner or later, you occasionally should segregate an issue, and the command-line interface provides the naked bones of SQL interacting with the database. The command line is furthermore the lingua franca (or, commonplace language) for SQL, which means that you may talk about SQL devoid of needing to instruct the consumer the pass to employ a specific application construction tool. extra or much less, the command-line strategy to problems neutralizes the often extraordinary preferences for software development materiel amongst users.

What are two or three programming habits developers should adopt besides the fact that they may materialize infatuation additional labor on the entrance end?

They should pick a style for writing SQL statements that permits them to sight read their code for punctuation and syntax compliance. It often means a bit more typing, however this may dramatically store time when trying to find a stray comma or key phrase. as an instance, an outstanding approach places commas on the left in pick and ORDER via clauses and ratiocinative AND/OR key words on the left of the where clause.

always employ table aliases, since it's easier so as to add content material with them than it's to retroactively add content material and desk aliases later to disambiguate selfsame name columns. different recommendations involve always using the AS keyword before column aliases to assist clarify that the column identify is represented "as" the alias. which you could succeed indentation patterns on CASE statements.

Michael McLaughlin is a professor of desktop information know-how at Brigham green college-Idaho and an Oracle ACE. He has worked for Oracle in consulting, lead and construction and is the writer of six books on Oracle technology.

Benchmarking Aurora vs MySQL: Is Amazon’s DB Really 5x Faster? | killexams.com real questions and Pass4sure dumps

In this post we’re taking a closer peep at Amazon Aurora to espy how it fares against MySQL and if it delivers on the plight of a 5x performance boost. Recently reaching universal availability, Aurora is Amazon’s home grown MySQL compatible database. Currently available on three AWS regions (Virginia, Oregon and Ireland) on top of RDS, Amazon’s Relational Database Service.

Java / Scala developer? Takipi replaces logging in production JVMs and lets you espy the variable status that caused each log mistake and exception.

Aurora is basically the next stage in the evolution of Amazon’s hosted services. If now we’re used to using EC2 for their servers, and RDS was introduced for optimized database instances, Aurora is the next step in this offering. Fully compatible with any operation you’d sprint through MySQL so no code changes are needed.

To espy a previous hurry test they ran and discover how each of the regions compare to each other, you can check out this blog post birthright here.

Why Amazon is edifice a fresh MySQL compliant database?

Unlike hosting a database on RDS, where they have additional performance benefits over EC2, monitoring, and quick installation features, Aurora even has some newer tricks up its sleeve. Seems infatuation a fresh database was required to create it easier for Amazon to further optimize performance and add features infatuation backups and autoscaling database storage – Which is not available on the basic MySQL instances. In that sense, we’re promised that Aurora would act infatuation MySQL if it was optimized to sprint on AWS from day 1.

A side consequence of this makes Aurora available only on AWS. So for example, you’d not be able to employ a local version for testing and would beget to completely rely on AWS instances. On the colorful side, migrating to Aurora from an existing database instance is just a matter of a few clicks.

Benchmark Results

To beget more of a hands on feel of how Aurora stands up to MySQL performance-wise we’ve set up a simple benchmark covering a write-heavy scenario using sysbench. To conclude this, we’ve used a similar configuration from a previous Aurora performance assessment ran by Amazon. In this version of the benchmark, they ran 4 different instances: The latest MySQL 5.6 on EC2 and on RDS, Aurora on RDS, and the release candidate version of the upcoming MySQL 5.7 on EC2. The exact setup they used and the raw results are available on the next section of this post. Let’s jump straight ahead and beget a peep at the findings:

Operations Per Second

Operations Per Second

Comparing operations per second for MySQL and Aurora on EC2 and RDS

1. MySQL 5.6 was 8% faster than Aurora – The fresh database didn’t provide the best results on this test, and far off from the 5x plight we’re used to hear from Amazon. Perhaps the biggest differences kick in on different setups with bigger DB sizes, but this just comes to display us the importance of trying it out with your specific employ case.

2. RDS provides up to a 60% performance profit over EC2 – A more significant dissimilarity is seen when they compare performance of databases on EC2 vs RDS. Using RDS provided considerable improvement over deploying the selfsame database on EC2.

3. MySQL 5.7 RC provided slightly better results than MySQL 5.6 – The next version of MySQL shows some progress, even though the RC benchmark sprint contained a considerable amount of ignored errors (full results are available through the link below).

4. When taking 95th percentile response times into account, Aurora takes the lead – Aurora was 20% better than MySQL 5.6 on RDS, and MySQL 5.7 was 20% better than MySQL 5.6 on EC2. RDS performed about 3x better than EC2.

** [Edit] delight note that optimizing MySQL’s my.cnf configuration would beget probably improved its results. Thanks @morgo!

Response Times

Response time

Comparing 95h percentile response times for MySQL and Aurora on EC2 and RDS

The Groundwork

The benchmark included setting up 5 r3.large instances on AWS: An EC2 machine which will sprint the benchmark, and machines with the databases themselves. MySQL 5.6 on EC2, MySQL 5.7 RC on EC2, MySQL 5.6 on RDS and Aurora which is only available on RDS. Then, we’ve created a test database with 250 tables and a 25,000 table size on each of the tested machines:

./sysbench –test=tests/db/oltp.lua –mysql-host= –mysql-port=3306 –mysql-user= –mysqlpassword= –mysql-db= –mysql-table-engine=innodb — oltp-table-size=25000 –oltp-tables-count=250 –db-driver=mysql prepare

Afterwards we’ve ran a variation of Amazon’s write-heavy benchmark described here (300 sec instead of 600 and 125 threads instead of 1000):

./sysbench –test=tests/db/oltp.lua –mysql-host= –oltp-tables-count=250 –mysql-user= –mysqlpassword= –mysql-port=3306 –db-driver=mysql –oltp-tablesize=25000 –mysql-db= –max-requests=0 –max-time=300 — oltp_simple_ranges=0 –oltp-distinct-ranges=0 –oltp-sum-ranges=0 –oltporder-ranges=0 –oltp-point-selects=0 –num-threads=125 –randtype=uniform run

So basically, the benchmark had 5 minutes to hurl total it’s got at each of the database instances, and report back on the results. The raw sysbench output is available birthright here:

– MySQL 5.6 on EC2– MySQL 5.7 RC on EC2– MySQL 5.6 on RDS– Aurora on RDS

Final Thoughts

As far as managed services go, Aurora is definitely a step in the birthright direction. Taking on hosted solutions for databases to the next level. But was it really necessary to create a fresh database to back autoscaling? We feel that RDS proved that it’s the birthright pass to sprint as far as hosted MySQL goes and it’s a suitable time to experiment with Aurora if you’re containing it to specific cases for testing in production. infatuation with any fresh technology that gets so immediate to the data at the core of your business, you’ll necessity to proceed with caution. With that said, a main ache point they didn’t address here is pricing and this is where Aurora holds the greatest plight against traditional full blown commercial databases.

Use an updated_at Column in Your MySQL Table (and create it update automatically) | killexams.com real questions and Pass4sure dumps

Nothing is worse than trying to figure out what went wrong with application data and finding out your tables don’t beget created_at or updated_at columns to store when rows are inserted or updated.

RAGE DROP TABLE TABLE_NAME

Another profit you acquire from having an updated_at column is efficient data replication into systems infatuation Pipeline, one of their products at RJMetrics. If they know which rows beget been updated recently, they can sort by that column and forestall redundant queries.

Don’t rely on properly formed queries to populate these columns! Let the database conclude it. Unfortunately, not total back it. Here’s how to create an automatically updating created_at timestamp in MySQL 5.5.

CREATE TABLE orders(id INT NOT NULL AUTO_INCREMENT,user_id INT NULL,amount FLOAT NULL,updated_at TIMESTAMP NOT NULL DEFAULT NOW() ON UPDATE NOW(),created_at TIMESTAMP NOT NULL, PRIMARY KEY(id));Query OK, 0 rows affected (0.00 sec)

So now your table has been created. The necessary fraction is the “updated_at TIMESTAMP NOT NULL DEFAULT NOW() ON UPDATE NOW()”This ensures that when fresh rows are added, the default value is NOW() and then it updates again on every update to that row.

Let’s insert a few rows.

INSERT INTO orders (user_id, amount, created_at) VALUES (1,101.45,NOW());Query OK, 1 row affected (0.00 sec) INSERT INTO orders (user_id, amount, created_at) VALUES (1,45.32,NOW());Query OK, 1 row affected (0.00 sec)

INSERT INTO orders (user_id, amount, created_at) VALUES (2,12.00,NOW());Query OK, 1 row affected (0.01 sec)

SELECT * FROM orders;+----+---------+--------+---------------------+---------------------| id | user_id | amount | created_at | updated_at +----+---------+--------+---------------------+---------------------| 1 | 1 | 101.45 | 2016-05-04 15:59:21 | 2016-05-04 15:59:21 | 2 | 1 | 45.32 | 2016-05-04 15:59:21 | 2016-05-04 15:59:21 | 3 | 2 | 12 | 2016-05-04 15:59:22 | 2016-05-04 15:59:22 +----+---------+--------+---------------------+---------------------3 rows in set (0.00 sec)

And now we’ll create an update to the third row.

UPDATE orders SET amount = 120.00 WHERE id = 3;Query OK, 1 row affected (0.01 sec)Rows matched: 1 Changed: 1 Warnings: 0

SELECT * FROM orders;+----+---------+--------+---------------------+---------------------| id | user_id | amount | created_at | updated_at +----+---------+--------+---------------------+---------------------| 1 | 1 | 101.45 | 2016-05-04 15:59:21 | 2016-05-04 15:59:21 | 2 | 1 | 45.32 | 2016-05-04 15:59:21 | 2016-05-04 15:59:21 | 3 | 2 | 120 | 2016-05-04 15:59:22 | 2016-05-04 16:00:07 +----+---------+--------+---------------------+---------------------3 rows in set (0.00 sec)

So even though they didn’t create a change to the updated_at column in their UPDATE statement, MySQL knew to update it. The suitable advice is that in MySQL 5.6 you can beget the database handle both columns.

CREATE TABLE orders(id INT NOT NULL AUTO_INCREMENT,user_id INT NULL,amount FLOAT NULL,created_at TIMESTAMP NOT NULL DEFAULT NOW(),updated_at TIMESTAMP NOT NULL DEFAULT NOW() ON UPDATE now(),PRIMARY KEY(id));Query OK, 0 rows affected (0.02 sec)

Don’t rely on developers to craft proper values for INSERT and UPDATE statements. Let MySQL conclude the work.

INSERT INTO orders (user_id, amount) VALUES (1,101.45);Query OK, 1 row affected (0.00 sec)

INSERT INTO orders (user_id, amount) VALUES (1,45.32);Query OK, 1 row affected (0.01 sec)

INSERT INTO orders (user_id, amount) VALUES (2,12.00);Query OK, 1 row affected (0.00 sec)

UPDATE orders SET amount = 120.00 WHERE id = 3;Query OK, 1 row affected (0.00 sec)Rows matched: 1 Changed: 1 Warnings: 0

SELECT * FROM orders;+----+---------+--------+---------------------+---------------------| id | user_id | amount | created_at | updated_at +----+---------+--------+---------------------+---------------------| 1 | 1 | 101.45 | 2016-05-04 17:30:19 | 2016-05-04 17:30:19 | 2 | 1 | 45.32 | 2016-05-04 17:30:19 | 2016-05-04 17:30:19 | 3 | 2 | 120 | 2016-05-04 17:30:19 | 2016-05-04 17:30:27 +----+---------+--------+---------------------+---------------------3 rows in set (0.00 sec)

Fascinating

Awesome, right? But what if you’re stuck on MySQL 5.5 and you absolutely necessity this? My colleague, Buck Ryan, sent me this excellent trigger to create that work, too.

CREATE TRIGGER orders__before_insertBEFORE INSERT ON ordersFOR EACH ROW SET NEW.created_at = NOW(), NEW.updated_at = NOW();

CREATE TRIGGER orders__before_updateBEFORE UPDATE ON ordersFOR EACH ROW SET NEW.created_at = OLD.created_at, NEW.updated_at = NOW();
