3.1.18 Secure permissions for the secondary archive log location - LOGARCHMETH2 OS Permissions

Information

1. Attach to the DB2 instance.
2. Run the following command from the DB2 command window to change the secondary archive log directory, if necessary-
db2 => update database configuration using logarchmeth2 <valid directory>
Additional steps for Windows (assuming that the logarchmeth2 parameter includes DISK)-
1. Connect to the DB2 host
2. Right-click on the secondary archive log directory
3. Choose Properties
4. Select the Security tab
5. Grant all DB2 administrator accounts the Full Control authority
6. Grant all other accounts read and execute privileges only (revoke all other privileges)
Additional steps for Linux (assuming that the logarchmeth2 parameter includes DISK)-
1. Connect to the DB2 host
2. Change to the secondary archive log directory
3. Change the permissions for the directory
