4. Recover the RAC database ASM11GR2.

Assume the Oracle binary is available and CRS is up. Mount all necessary file systems if the

file systems are used. In this case, asmlib is used, so scan the oracleasm disks and then mount

all database diskgroups.

a. Scan oracleasm devices.

dl160g6-13:# oracleasm scandisks

b. Mount ASM diskgroups.

alter diskgroup ASM11GR2_ARCHDG mount;

alter diskgroup ASM11GR2_ARCHDG2 mount;

alter diskgroup ASM11GR2_DATADG mount;

alter diskgroup ASM11GR2_DATADG2 mount;

alter diskgroup ASM11GR2_REDODG mount;

c. Start the ASM11GR2 database.

d. Repeat this operation to bring up other RAC nodes.

Recovering to the Asynchronous Periodic Backup System when the Local

and Synchronous Backup Systems are Unavailable

In this scenario, the local system S256 and synchronous backup system S347 are both unavailable.

The primary database ASM11GR2 cannot be brought up using the local system S256 and cannot

be failed over to the synchronous backup system S347.
