BIG/db Configuration Keys
Supported BIG/db configuration keys
The BIG/db is a database that contains configuration elements for the BIG-IP Controller. Currently, the following configuration options are supported by BIG/db:
Using the Failover and Cluster keys
The switch-over daemon (sod) uses all .Failover keys (Table 8.1). The sod and the mirroring daemon (sfd) use all .Cluster keys. If you change one of these values, you must update the BIG-IP Controller configuration with the bigpipe failover init command. This command forces sod to reread the BIG/db database and use the new values. To run this command, type the following:
bigpipe failover init
For more information about sod, see sod, on page 7-2.
The BIG/db keys that store fail-over information
| Fail-Over Key Name |
Description |
| Common.Bigip.Failover.AwaitPeerAliveDelay |
Delay in seconds before testing whether peer is active. The default value is 2. |
| Common.Bigip.Failover.AwaitPeerDeadDelay |
Delay in seconds before testing whether the peer has failed. The default value is 1. |
| Local.Bigip.Failover.UnitId |
This key is required. Each controller must have a unique unit ID of 1 or 2 in the event that network communication is not possible with its peer. |
| Common.Bigip.Failover.ActiveMode |
Use active-active mode if set to 1. By default, this is off and active/standby mode is used. |
| Common.Bigip.Failover.ManFailBack |
If using active-active mode, the fail-over mechanism waits until receiving a command before surrendering resources to a rebooted machine. |
| Common.Bigip.Failover.NoSyncTime |
By default, one BIG-IP Controller synchronizes its time with the other. Set this key to 1 to turn off the time synchronization feature. |
| Common.Bigip.Failover.DbgFile |
File into which sod logs the fail-over debug information. |
| Common.Bigip.Failover.PrintPeerState |
The default value for this key is 0. Fail-over daemon (/sbin/sod) writes the state of its connection to its peer, hardwire and/or network. This information is written to the fail-over daemon's debug log file. |
| Common.Sys.Failover.Network |
Use the network (via the sfd) as a backup to, or instead of, the serial line for fail-over if this value is 1. By default, this feature is off. |
| Common.Bigip.Cluster.ActiveKeepAliveSec |
The default value for this key is 0. An active unit sends a heartbeat message to its peer with this frequency. Default is 1 second. |
| Common.Bigip.Cluster.StandbyTimeoutSec |
Consider the peer BIG-IP Controller failed if no message is receied within the timeout period. Used by network fail-over. Default is 3 seconds. |
Using StateMirror keys
The mirroring daemon (sfd) uses all StateMirror keys (Table 8.2). If you change one of these values, you must reboot the BIG-IP Controller to load the new configuration and restart the sfd.
The BIG/db keys that store state mirroring information
| State Mirroring Key Name |
Description |
| Common.Bigip.StateMirror.DbgFile |
File into which debug information is written, required if debug level is specified (below). |
| Common.Bigip.StateMirror.DbgLevel |
The debug level is composed of the following options: 1 - log reads and writes 2 - log connection attempts and results 4 - log state changes 8 - open log files in append mode, the default is to truncate the files when opening. The debug level is zero by default. |
| Common.Bigip.StateMirror.NoGC |
By default, state mirroring causes mirrored data structures to be deleted when it receives a new connection. This key is brought up to date by the controller's peer. This can cause a delay if the system is absolutely loaded. Turning off the GC is provided as an option. |
| Common.Bigip.StateMirror.ActiveFile |
Enables writing of data from the active unit's kernel into the ActiveFile file. This data file can be read with the sfread program. |
| Common.Bigip.StateMirror.StandbyFile |
Enables writing of standby data into the StandBy file. This data file can be read with the sfread program. |
| Common.Bigip.StateMirror.PeerListenPort |
Port on which the BIG-IP Controller listens for connections from the active unit. Default is 1028. |
| Local.Bigip.StateMirror.Ipaddr |
IP address of this BIG-IP Controller. |
| Local.Bigip.StateMirror.PeerIpaddr |
IP address of this BIG-IP Controller's peer controller. A value is required. |
Using Gateway Pinger keys
The following table lists the Gateway Pinger keys.
The BIG/db keys that store gateway pinger information
| Gateway Pinger Key Name |
Description |
| Local.Bigip.GatewayPinger.Ipaddr |
IP address or host name of the gateway router for the BIG-IP Controller |
| Local.Bigip.GatewayPinger.Pinginterval |
Ping interval of this BIG-IP Controller gateway pinger |
| Local.Bigip.GatewayPinger.Timeout |
Timeout of the BIG-IP Controller gateway pinger |
Using configuration synchronization and Interface keys
The First-Time Boot utility sets the configuration syncronization and Interface keys (Table 8.4 and Table 8.5). You should not change these keys manually with bigdba.
The BIG/db keys that store configuration synchronization information.
| Configuration Synchronization Key Name |
Description |
| Common.Bigip.ConfigSyncKey |
Used for synchronizing the configuration of two BIG-IP Controllers. |

First-Time Boot utility fields. These fields are populated by the First-Time Boot utility. These represent a small fraction of the actual fields produced, as the rest are dynamic and dependent upon First-Time Boot utility user input such as host names and interface identifiers. |
The BIG/db keys that store interface information
| Interface Key Name |
Description |
Local.Bigip.Interface.*.Name
Common.Bigip.Interface.*.Name |
The interface name is used as the key for querying or modifying its attributes. The key is common by default, but can be local to accommodate redundant BIG-IP Controllers with different interface names. However, the interface names must all be local or all be common. |
Common.Bigip.Interface.*.AddrList.*.Address
Common.Bigip.Interface.*.AddrList.*.Netmask
Common.Bigip.Interface.*.AddrList.*.Broadcast |
Attributes of an interface's addresses. Currently, the BIG/db contains only shared IP addresses. |
| Common.Bigip.Interface.*.AddrList.*.Type |
Type is Shared or True. Shared is associated with an IP alias, True is associated with an IP address. |
| Common.Bigip.Interface.*.AddrList.*.UnitId Common.Bigip.Interface.*.AddrList.*.VlanTag |
The unit number with which the shared IP alias is associated. |
