Previously we introduced:Oracle 10 Gb Memory StructureIn this section, we will introduce the 10 Gb memory structure of Oracle.Sharing poolNext, let's take a look at this part. The third component of SGA is the shared pool. The shared pool is the memory area for syntax analysis, compilation, and execution of SQL, pl, and SQL programs. The shared pool includes the library cache of the library Buffer and the D

What we want to introduce today is the operating language (DML) for Oracle to use FIRALL to process some non-consecutive arrays and execute relevant data in PL/SQL loops) in fact, it is a very time-consuming task, because every cycle needs to be switched from the PL/SQL engine to the SQL engine. Applying FORALL is a better way to submit a set of temporary values to SQL statements at a time. Before Oracle 10 Gb, The FORALL statement syntax can only pro

Php obtains the file size and converts the file size to gb, mb, and kb. this code uses the php program to obtain the file size and displays the file size as gb, mb, the code of kb code is very intelligent. the code is as follows: Function sizecount ($ filesize ){ If ($ filesize> = 1073741824 ){ $ Filesize = round ($ filesize/1073741824*100)/100. 'GB '; } El

Solutions to Em-related problems in Oracle 10 GB The EM in Oracle 10 Gb adopts the web form to manage databases and related services. However, some em-related problems may occur during use. Based on the prompts from the peers and the actual experience of the author, I have summarized some ideas and hope to help related fans:(1) After the Database Console is started, 1) The database instance has no inform

1. Get the file size 1. Use the stat function to obtain the file size. Let's take a look at the struct structure. The file size is defined as follows: # Ifndef _ use_file_offset64_ Off_t st_size;/* size of file, in bytes .*/# Else_ Off64_t st_size;/* size of file, in bytes .*/# Endif Generally, we use _ off_t, that is, long int (4 bytes,-2147438648 ~ + 2141438647), while _ off64_t is long int (8 bytes,-9223372036854775808 ~ + 9223372036854775807 ). We try to use stat to read a 4.2g file and chec

The customer brought a virtual machine. As a result, the C drive is divided into 126 GB. As shown in: When you use csupload for upload, the error "thevhds logical size of 130048 MB exceeds the system maximum of 66560mb" will appear. Solution: shrink disk C Procedure: 1. Shut down thevm. 2. Copy vhd fileto your machine from where you will be using Ming csupload. 3. Attach locallycopied vhd from disk management console. 4. Right clickand select o

Tags: des blog Io OS Java ar strong I believe many people have encountered the same problem. During map loading, the memory occupied by IE has been increasing, and IE crashes when it reaches 1g or more. I checked it online and found many results. I will summarize them below: A). 64-bit Ie can reach up to 4 GB memory, but skyline6.5 only supports IE-32bit, it is said that 6.6 will support Google, fireforx, IE-64bit and other browsers, but currently

Oracle uses Incomplete Database-level recovery to solve the logical errors caused by data loss or human error before 10 Gb. After 10 Gb, RMAN introduces a new feature called "tablespace point-in-time recovery", TSPITR for short, which can actually achieve Incomplete recovery at the tablespace level, of course we know that after 10 Gb, the flashback feature can al

If you want to restore a database on a colleague's machine to your own machine, the DMP file provided by the colleague cannot be used. I suddenly thought of Oracle 10 Gb, and I was still in the Oracle 9I stage. Back up again with your own 9I client, resulting in a EXP-00003 error. I checked on the Internet that the BLOB field is used in the table (it seems that this field does not affect Data Storage). By the way, I found a solution. After using this

Use the filesize () function command to calculate the file size. The value 1 must be an output of GB, MB, KB, and B. 2. the order of magnitude must be greater than 1 and less than 1024, and two decimal places must be retained; Start: Copy codeThe Code is as follows: $ len = filesize ("1. rmvb "); $ I = 4; While ($ I ){ If ($ out = $ len/pow (1024, $ I)> 1.0 | $ I = 1 ){ Switch ($ I ){ Case 4: {printf ("%. 2f TB", $ out); break ;} Case 3: {prin

PHP implements the original method of converting Byte to KB, MB, GB, and TB. This example describes how to convert the number of bytes in PHP to KB, MB, GB, or TB. We will share this with you for your reference. The details are as follows: The previous section describes how to convert the number of bytes in java to KB, MB, GB, and TB. Here, PHP is used to impleme

The uninstallation and installation of the Oracle Database 10 Gb database system are equally important. Many users are concerned about how to completely uninstall the Oracle system without affecting the use of the operating system. Different Versions of Oracle have the same uninstall method. There are three ways to uninstall ORACLE: manual uninstallation of Incomplete installation, uninstallation of independent components, and full uninstallation of d
