The following are recommended time policies and standards:
· All machines should be synchronized to Coordinated Universal Time (UTC). Strategies must be developed around distribution of UTC time providers and systematic management of how each machine becomes synchronized.
· Cells need a strategy for deploying time services in a heterogeneous infrastructure containing multiple network protocols and multiple namespace directories, which complicate deployment and management.
· For intracell communications:
¾ Setup three DTS servers per cell.
¾ If the cell spans several LANs, setup three DTS servers per LAN. In this case, DTS setup is more complicated.
¾ Any DCE host that is well-run and reliable can be a DTS server.
· For intercell communications:
¾ If your cell needs to communicate with other cells, your cell must have the correct time, within about 2 minutes. To achieve this, you can install a time provider.
¾ Typically, any machine that is a CDS or security server also acts as a DTS server.
¾ If your cell has a DNS name, send registration information to the BIND administrator.
¾ Setup trust relationships with other cell's using the rgy_edit cell command.
