Sample text

From a user perspective, OCR management and maintenance works the same as in previous versions, with the exception of OCR recovery, which is covered later in this section. As in previous versions, the OCR is backed up automatically every four hours. However, the new backup location is /cdata/. A single OCR file is stored when an external redundancy disk group is used. It is recommended that for external redundancy disk groups an additional OCR file be created in another disk group for added redundancy.

The following query, when run on the ASM instance, reflects that it is an ASM instance: ASM_SQL> SELECT INSTANCE_NAME FROM V$INSTANCE; INSTANCE_NAME ---------------+ASM The ASM instance is generally named +ASM, and in RAC configurations, the ASM system identifier (SID) is named the +ASMx instance, where x represents the instance number. The ORACLE_SID environment variable can be set as follows: export ORACLE_SID=+ASM1 When the INSTANCE_TYPE=ASM parameter is set, it signals the Oracle initialization routine to start an ASM instance and not an RDBMS instance.

In this case, the database foreground communicates directly with the ASM instance to coordinate the operation (this is covered in Chapter 2). Each database instance maintains a pool of connections to its ASM instance to avoid the overhead of reconnecting for every file operation. Additionally, the RDBMS instances never directly update ASM metadata. ASM metadata is managed and written only by the ASM instance. indd 30 5/31/13 5:20 PM Oracle-Regular / Database Cloud Storage / Vengurlekar & Bagal / 015-2 Chapter 3: ASM Instances 31 Managing ASM Instance ASM is the volume manager for all databases that employ ASM on a given node.
