The following articles mainly introduce how to bind 10 Gb of Oracle to forall bulk collect in batches, we all know that batch binding generally reduces context switches between PL/SQL and SQL engines to improve performance. Bulk binds can be bound in batches: (1) Input collections, use the FORALL statement to Improve the Performance of DMLINSERT, UPDATE, and DELETE operations. (2) Output collections, use bulk collect clause, used to improve the perfor

Differences between a transaction-based temporary Oracle table under 11 GB and 12CThe transaction-based temporary tables in Oracle differ from those in 11g and 12C. After collecting statistics on the temporary tables, the former records are cleared, and the latter does not, this is an important difference. 12C is used in the company environment, and 11 GB is used at the site. Using temporary tables will slo

Song Bang Mobile power name generally starting from 501, now it's all out to 54W. Lucky, huh?Perhaps you will ask, a name to get good, there is sales? Of

New Features of Oracle 10 GB-code obfuscation Author: Fuyuncat Source: Www.hellodba.com Before Oracle 9i, a command 'warp' was provided to encrypt the code. However, it is based on scripts in the command line mode. In 10 Gb, the Oracle package dbms_ddl provides a new function create_wrapped to confuse the code. Example:SQL> declare2 v_protex varchar2 (2000): ='3 create or replace pr

Having stayed at school, I went over PhP and looked at the previously written functions. I suddenly wanted to write the known file size and sort the data. For example: 1.3G, 153 MB, 458kb, 998 m, 0.99g (the difference between MB and MB is not considered here, and generally does not involve the operation of MB, so MB, MB, and MB are regarded as mb. In fact, MB = 8 * MB) The function is as follows: PHP Function Sortsize ( $ Arr ){ $ Arr2 = $ Arr ; $ Arr3 = Array (); If (! Is_array ( $

Install Oracle 11g single-instance database on Linux under vmvm 1.

My plan is: The VM allocates MB of memory. Of course, if the host memory is sufficient, it can be faster to s

Why should we discuss this issue? It is rooted in history. Let's start with Oracle 10 Gb. Before 11G, if you want to add a new column to a large table and the new column has a default value, if you want to use alter table xx add xx_1 number default 1000; this type of statement settings will be very handy! Its action is to add a column and update the column. If the table is very large, a very large transaction will be generated. Because it is a ddl ope

Use Crontab in RedHat Linux to implement Oracle 10 Gb scheduled backup (including SFTP download instructions ). This is to say that regular backup is a hot backup, that is, writing a shell script. The syntax is oracle10g, and 9i is slightly modified (using exp syntax) After the scheduled backup, you can use the client machine to automatically download, use the sftp client, and set it to automatic download. If not, you can go to the Internet to find th

Starting from 10 Gb, Oracle began to provide shrink commands. If our tablespace supports automatic segment space management (assm), we can make Use this feature to narrow down the segment, that is, to reduce hwm. here we need to emphasize that the new 10 Gb feature is only valid for the assm tablespace, otherwise it will be reported ORA-10635: Invalid segment or tablespace type. Here, we will discuss how to

For versions earlier than 10 Gb, you must use the alter_database/schema_tab_monitoring process of dbms_stats or create/alter table... monitoring enables table monitoring. In 10 Gb, the keywords monitoring and nomonitoring are out of date. If you specify or cancel monitoring for a table in create/alter table, this keyword is ignored, table monitoring features are controlled by statistics_level. When statisti
