In Linux you can use Asmlib to manage these tasks, but it's seen as an additional layer of complexity and have never reall Y gained any popular
Do not use the form of service, directly in/etc/rc. add a script for local: su-oracle-c "/home/oracle/product/10.2.0/db_1/bin/dbstart". Change ORACLE_HOME_LISTNER of dbstart to $ ORACLE_HOME.Restart the system. The oracle instance is not started.

Oracle RAC Environment ASM Disk Group is forcibly deleted with kfed tool for perfect recovery of mistakenly deleted disk group casesIn some cases, may be due to misoperation, not small drop diskgroup, this time do not be nervous, this type of failure, can be kfed for a perfect recovery (data 0 lost). If the relevant ASM disk is further damaged, subsequent restores will be cumbersome, You may need to use the

Chapter One: ASM introduces 1.1 asm motives:Program analysis, generation, and conversion techniques can be applied to many scenarios:1. Program analysis, from simple syntax parsing to complete semantic analysis, can be applied to find potential bugs in the program, find useless code, reverse engineering code, and so on.2. Code generation is applied in a variety of compilers: both traditional compilers and d
1.1 ASM Motive:Program analysis, generation, and conversion techniques can be applied to many scenarios:1. Program analysis, from simple syntax parsing to complete semantic analysis, can be applied to find potential bugs in the program, find useless code, reverse engineering code, and so on.2. Code generation is applied in a variety of compilers: both traditional compilers and distributed programming stubs or skeleton compilers, instant compilers, and
Starting from Oracle11gR2, GI has integrated ASM, and OCRVOTEDISK is also stored in the ASM disk group (which needs to be stored on bare devices before 11gR2). At the same time, ASM has a larger function than 10 Gb. Starting from Oracle 11gR2, GI has integrated ASM, and OCR/VOTEDISK has also been stored in the
For disks that are managed with ASM, you need a means to consistently identify disk devices and their proper owning relationships and permissions. In a Linux system, you can use Asmlib to perform this task, but the disadvantage of doing so is to add an extra layer to the operating system, which leads to the complexity of management, and the way to configure ASM with Asmlib is now no longer popular.An altern
ASM (Automatic Storage Management) is a new feature introduced in oracle10g R2 to simplify the management of Oracle databases, which is Oracle's own volume manager, which is used primarily to replace the LVM provided by the operating system. It not only supports single instances, but also supports RAC very well.First, the Origin of ASMASM is a new feature introduced in Oracle 10g R2 to simplify the management of Oracle databases, a volume manager prov
CHAPTER 10 ASM Persistent Data Structures Like traditional file systems and volume managers, ASM stores metadata to describe and track the content of a disk group. All metadata descriptions are stored in the composition and content of the above ASM disk group, which enables the disk group to implement self-description. The AS

Comparison of two-live solutions: ASM vs V-plexWang WenjieOracle Company Principle System AnalystOracle Advanced ServicesThe evolution of Oracle Database Center disaster Recovery has evolved over the years from initial cold backup, to hot backup, to storage replication, to Dg,adg,rac one node, RAC, and eventually to the hottest dual-live dual-center architecture, This is the remote RAC (Extended RAC) we often call.General pre-Sales engineers to realiz
In some scenarios, if there are problems with the host in the RAC environment, such as hardware failure, we need to store the startup database as soon as possible, and restore the business, then we need to migrate the previous RAC environment to the new host environment, I tested 11.2 and 12.1 of RAC, the recovery process is very fast, basically is the process of installing software, if the real scenario to restore business, there are two ways:1, follow my method to reinstall the host, restore t

Label:First, ASM (Automatic storage management) for the reason: ASM is a new feature introduced in Oracle 10g R2 to simplify the management of Oracle databases, a volume manager provided by Oracle itself, primarily used to replace the LVM provided by the operating system, which not only supports single instancing, but also supports the RAC very well.

CHAPTER ASM Persistent Data structuresAs with traditional file systems and volume managers, ASM storage metadata is used to describe and track the contents of a disk group. All metadata describes the composition and content of the ASM disk group stored above, which enables the disk group to be self-describing. ASM Disk
Oracle 10R2 releases the asmcmd tool to manage files stored in asm.1. To use the asmcmd command, you must first start the asm instance. Otherwise, the following error occurs: Rac2-> asmcmd-pA ORA-01034: ORACLE not availableORA-27101: shared memory realm does not existLinux Error: 2: No such file or directory (dbd error: OCISessionBegin)2. To use asmcmd, you must specify ORACLE_HOME and ORACLE_SID. Note that
Oracle 11gR2 uses gpnp profile to store the spfile path of ASM Since Oracle 11gR2, GI has integrated ASM, and OCR/VOTEDISK has also been stored in the ASM disk group (which must be stored on bare devices before 11gR2 ), at the same time, the functions of ASM are greatly enhanced by 10 Gb. Let's first introduce the foll
My RAC Virtual Machine reported that diskgroup space was insufficient during Backup yesterday, so I added asmdisk to my schedule. When installing RAC, I had 2 ASM diskgroups + DG, respectively, + recoverydest: Now + recoverydest has insufficient space, and no redundant asmdisk is created during installation. Only now can the remaining space be recovered. At the same time, two nodes can create asmdisk with virtual machines, then, run the alter diskgrou
