Each time the ASM instance starts the ASM or database, it will allocate a shared memory area named system global zone (SGA) and start the Oracle ASM and da

Occasionally a valid ANSI/ISO program may be incompatible with the extensions in gnu c. To deal with this situation, the compiler option-ansiDisables those GNU extensions which are in conflict with the ANSI/ISO standard. On systems using the gnu c library (glibc) It also disables extensions to the C standard library. This allows programs written for ANSI/iso c to be compiled without any unwanted effects from GNU extensions. For example, here is a valid ANSI/iso c program which uses a variable ca

allocation: I/O is automatically distributed across all available Disks without manual intervention. This reduces the possibility of hot spots.3 Band Width: segments in the redo log file can be subdivided (K for faster transmission rate). For data files, the band width is slightly larger (MB, to transmit a large number of data blocks at a time ).4 Buffer: the ASM file system directly performs input/output

There are some basic concepts about ASM in the previous section, such as: The first class version in visit, the description of the method, the description of the reference, etc., which are described below.Class version A Java binary class file that has a version that corresponds to a different JDK version. Therefore, ASM provides several constants to specify the version of a class, which are defined in the

ASM instances using the Asmcmd tool to manage ASM catalogs and files

In the ASM instance, all files stored in the ASM Disk group are inaccessible to the operating system commands and therefore cannot be manipulated using regular commands to manipulate the files on the ASM disk. Fortunately, we have asmcmd tools to do this work in lieu of operating system commands. The Asmcmd tool provides common commands similar to the operating s

A friend came to me and said they had switched the previously stored to AIX direct-attached storage to a storage network with a fibre switch, and the RAC failed to start, allowing me to support it.
