Configuring the database
The database accounts and files to be backed up with a Hot Backup configuration must be specified.
There are two options for this specification:
Procedure
- All files in the database (Not Recommended)
- Select Accounts/Files in the database
It is recommended that you only log those files that need to be logged to the secondary server. To specify the account and files to log, the D-Pointers on these accounts and files can be changed using the set-dptr command (See the D3 Reference Manual for more information on the details.). The flags relevant to Hot Backup are:
| Flag | Description |
|---|---|
| DL | Log this file. |
| DT | Do not log this file (applicable if logging all files). |
| DX | Do not save this file during a regular backup and do not log this file via Hot Backup. |
| DY | Save this file, but not its contents during a regular backup. Also, do not log this file via Hot Backup. |
See the D3 Reference Manual for more information on the set-dptr command.
Complete the instructions below to turn the logging attribute on for an account.
-
Enter:
set-dptr +L accountname (A
where accountname is the name of the account.
The example above illustrates running the set-dptr command on the hbtest account. Attribute 1 in all D-Pointers in the hbtest account is changed from D to DL for both dictionary and data levels.
Note:-
The set-dptr command changes any item in the MD or dictionary level of a file whose attribute 1 value starts with a D.
-
The (d option of the set-dptr command (when used with the +l attribute) ensures that newly logged files are synchronized with the Hot Backup secondary server.
-
To change multiple accounts, you can run the set-dptr command on each account or build a list containing the account names that you wish to process and run the set-dptr command on the active select-list. For example:
: get-list acclist > set-dptr +L (A
The example above illustrates the set-dptr command working with an active select-list containing file names.
