See the sfrac_ckptcreate(1M) and sfrac_ckptmount(1M) manual pages for more information. Also refer to the examples, Creating Storage Checkpoints Using sfrac_ckptcreate and Mounting Storage Checkpoints Using sfrac_ckptmount.
To verify that a Storage Checkpoint is error-free using the command line
-
Create and mount a Storage Checkpoint:
$ sfrac_ckptcreate -S DB12 -H $ORACLE_HOME
Storage Checkpoint Checkpoint_903937870 created.
$ sfrac_ckptmount -S DB12 -c Checkpoint_903937870 \
-m /ckptmnt
-
Examine the content of the Storage Checkpoint:
$ ls -l /ckptmnt/db01/DB12
