The block size is number of bytes of data the SAP on Oracle database reads for backup and restore operations. The default value is 1MB.
Set the block size to 0 to use the default RMAN block size.
Note
The block size value must be a minimum of 32 KB and be divisible by 16.
When you set this value in the CommCell Console, the client init<SID>.sap profile is automatically updated with the BLKSIZE parameter similar to the following line:
RMAN_PARMS="SBT_LIBRARY=$[/opt/commvault/Base64/libobk.so],BLKSIZE=$[32768],ENV=(CvClientName=$[client_name]1,CvInstanceName=$[Instance001])"
Procedure
-
From the CommCell Browser, expand Client Computers > client > SAP for Oracle.

Right-click the instance and then click Properties.
-
Select the size of the block for backup and restore operations. On the Details tab of the Instance Properties dialog box, in the Block Size box, type the block size.
