Base Platform Software

Following are the elements of the base platform software.

OSI Stack

This package implements the OSI protocol to allow communications between the LSMS and the NPACs.

LSMS HA

LSMS High Availability (HA) is software for a two-node cluster that provides automated switchover from an active server to a standby server when a server or monitored application experiences a failure. In the LSMS, the two servers are peers: either server can act as the active server (although only one server at a time can be the active server). When either automatic or manual switchover causes the standby server to become the active server, it can continue to be the active server until another switchover is needed.

Note: After switchover, the state of the previously active server is UNINITIALIZED "INHIBITED". As soon as possible, you need to perform the procedure described in Starting a Server to return the state of that server to STANDBY so that it is available when switchover is needed again.
