Re: Snapshots vs PL/SQL?

Hello,

    I am a DBA and a PL/SQL Developer.

    I am having ALL snapshots fast refresh across three instances from 2 other different
instances with no issues.

    My instances as 8.1.6 and 8.0.5

    Total number of snapshots are over 100, with snapshot logs on the master sites.

    I don't know what your specifics are, but basic replication operates as designed if
implemented correctly.

    If you have any specific questions, please post.

    Thank you,

john
