Label:This article introduces two major branches of Oracle memory database, TimesTen and database in-memory, which are well worth reading and are fully covered by the important features of both technologies, allowing readers to quickly get a comprehensive understanding of the key points of Oracle's in-Memory database technology, After reading this article, we suggest that we can read the original text in the reference again.OverviewAs memory capacity grows and prices fall, it is possible to put

. You need to adjust SORT_AREA_SIZE, HASH_AREA_SIZE, BITMAP_MERGE_AREA_SIZE, PGA (Process Global Area) is a private memory Area of server process. It contains Global variables, data structures, and some control information. In Oracle8i, PGA adjustment is very complex. You need to adjust parameters such as SORT_AREA_SIZE, HASH_AREA_SIZE, BITMAP_MERGE_AREA_SIZE, and CREATE_BITMAP_AREA_SIZE. In ORACLE9I, you only need to adjust PGA_AGGREGATE_TARGET. -- PGA_AGGREGATE_TARGET initialization settings T

storage method1. B * tree indexesB * tree indexes are the most common indexes. Their storage structure is similar to the index structure of books. There are two types of storage data blocks: branch and leaf. The branch block is equivalent to a large directory of books, A leaf block is equivalent to a specific index page. Generally, both the index and the unique constraint index use the B * tree index. 2. Bitmap IndexBitmap index storage is mainly used to save space and reduce ORACLE access to d

The OLTP on the top left adopts the shared storage mode and memory convergence technology. It is similar to the mongolerac. The only difference is that there is an independent node management server and the node management backup service. OLTP on the top left adopts shared storage and memory convergence technology. It is a type similar to oracle rac. The only difference is that it has an independent node M

which locks to upgrade. If you replace these row locks with a table lock, it will no longer exceed the MAXLOCKS value, and the lock upgrade will stop. Otherwise, the lock upgrade will continue until the percentage of the lock list held is lower than that of MAXLOCKS. The MAXLOCKS parameter multiplied by the MAXAPPLS parameter cannot be less than 100. Although the upgrade process does not take a long time, locking the entire table (as opposed to locking individual rows) reduces concurrency, in a

plans, oracle always emphasizes that binding variables must be used for application system design, that is, a variable is used to replace the literal value that originally appeared in the SQL statement. For example, for the following three SQL statements: Select col1 from t where col2 = 1;Select col1 from t where col2 = 2;Select col1 from t where col2 = 3; As we can see, these three SQL statements are almost the same, only the literal values (1, 2, 3) IN THE where condition are

became strictly compliant and hindered its innovation. The author Shivprasad has accumulated some experience in his usual work projects and introduced 11 data form creation techniques to us. This can be used as a reference when designing data forms, to enrich our application experience. Rule 1: What is the essence of an (OLTP or OLAP) application? When you begin to create a data table with a single time, First, analyze the nature of the program you

directions. The B-tree index stores the ROWID value of each data row with values in the index column. Oracle does not index rows with NULL values in the index column. If the index is a combination of multiple columns, and the column contains NULL values, this row will be in the index column containing NULL values, it will be processed as NULL (treated as NULL ). Tip: the value of the index column is stored in the index. Therefore, you can create a composite index that can directly meet querie

. From the above test results, we can see the impact of indexes on data modification. Iii. Index classification by storage method 1. B * tree indexes B * tree indexes are the most common indexes.

Datastage, Infosphere CDC, Infosphere Warehouse, and Cognos to quickly create data Analysis applications.

Microsoft SQL server reporting service step by step I have been reading MICROSOFT for two days. I think MICROSOFT's book has something in common: easy to understand and easy to understand the software framework; For example, for Reporting Service, authoring reports ----> manage reports -----> delivering reports, the detail of each step can be further understood by yourself, but the three steps are mastered, you have mastered the simple design of OLTP

Let's talk about FoundationDB and foundationFoundationDB Apple acquired FoundationDB1, and the latter immediately changed from open source to closed source. To be honest, I have never noticed such a DBMS product 2 before. From the official website, some of its design concepts are more practical. After all, Distributed DBMS has many problems that are hard to solve, it is unrealistic to achieve the same level as traditional RDBMS such as Oracle in the short term. For example, it focuses on core fe
