This query is generated whenever CheckEachNewOpenConnection is 1 and eDirectory needs to
open a new connection for backlinking or when CheckEachAlreadyOpenConnection is 1 and
eDirectory needs to reuse an already existing connection.
• Version (Input Only, Type INTEGER)
The version of eDirectory.
• ExpirationInterval (Input and Output, Type INTEGER)
If ConnectionIsAlreadyOpen is TRUE, ExpirationInterval is set to the expiration interval
already set on the existing connection. Otherwise, it is set to the ExpirationInterval assigned in
the NDS_BACKLINKS query. A 0 value indicates that the default (2 hours) should be used.
On exit, the value of this variable is assigned as the expiration interval for the connection.
• ConnectionIsAlreadyOpen (Input Only, Type BOOLEAN)
This variable is TRUE if eDirectory can reuse an existing connection and FALSE if it needs to
create a new connection.
• ConnectionLastUsed (Input Only, Type TIME)
If ConnectionIsAlreadyOpen is TRUE, then ConnectionLastUsed is the last time that a packet
was sent from eDirectory using this connection. Otherwise, it is 0.
Sample NDS_BACKLINKS
Before eDirectory checks any backlinks or external references, it queries WAN Traffic Manager to
see if this is an acceptable time for this activity. NDS_BACKLINKS does not have a destination
address; it requires a NO_ADDRESSES policy. If WAN Traffic Manager returns DONT_SEND,
backlink checking will be put off and rescheduled. The following variables are supplied:
• Last (Input Only, Type TIME)
Value Description
<0, 0 Use the default expiration interval (default).
>0 Expiration interval to be assigned to this connection.
Value Description
TRUE eDirectory determines that it already has a connection to this address
and can reuse that connection.
FALSE eDirectory does not have a connection to this address and must create
one.
Value Description
TRUE ConnectionLastUsed is the time that eDirectory last sent a packet on
this connection.
FALSE ConnectionLastUsed will be 0.
