As with other LDAP controls, the Persistent Search control is supported by CA Directory.
To enable Persistent Search, you set the following flag on the DSA:
set persistent-search = true;
Persistent searching can be used only where the namespace is managed by a single DSA. Only the local namespace is accessed, which means that there is little point in using it with routers.
For example, persistent searching does not work in the following situations:
- If you have update and search DSAs, then the persistent search is not likely to work unless it is done in the router.
- If there are multiple routers, then persistent search in the router does not work. Instead, it must be done on the update DSA.
- If there is query streaming and persistent search is done in the update DSA, the search is never sent to the update DSA, so it does not work in this situation either.
The following is simple method to verify that Persistent Searches are being correctly handled.
