If the transaction logs are available, the recovery procedures in Table 9-4

 

guide you through replaying the IDB transaction logs. Refer to

 

“Replaying IDB Transaction Logs” on page 430.

 

 

If the transaction logs are not available, you can update the IDB by

 

importing media. Refer to “Updating the IDB by Importing Media” on

 

page 433.
