About nbproxy processes on NetBackup master servers
When OpsCenter is connected to a master server, you may find one or more nbproxy processes running on the master server. You may also see nbproxy processes when NetBackup-Java GUI or NetBackup-Windows GUI request certain data from NetBackup (like LiveUpdate , storage lifecycle policies).
Most of the nbproxy processes are started, managed, and removed by NBSL. This section talks about the nbproxy processes that NBSL manages.
Note:
Not all nbproxy processes on the master server are managed by NBSL. For example, some of the nbproxy processes are managed by nbjm and nbpem.
An nbproxy process runs to retrieve the following NetBackup data for OpsCenter:
Policies
Catalogs
Storage lifecycle policies
LiveUpdate
Client details
Note the following points about the NBSL-managed nbproxy processes:
If the data collection for a master server is disabled or a master server is removed from the OpsCenter console, all nbproxy processes are stopped immediately.
If OpsCenter crashes (or is abruptly closed), the nbproxy process is removed within an hour.
If NetBackup is stopped (and NBSL is already killed), all nbproxy processes are stopped immediately.
If NBSL crashes (or is abruptly closed), all nbproxy processes exit within 10 minutes.
