It does not convert columns that are too closely linked with Oracle physical structures or have no equivalent in SQL Server 2014. The following views can be migrated automatically to SQL Server views: ALL_INDEXES DBA_INDEXES ALL_OBJECTS DBA_OBJECT...
Note*: The number of standby log files (in this case for our single instance primary database MSDP) is equivalent to (#of online logfile groups + 1). We do not need to multiplex standby redo log files, as it is only used for recovery. After this, we need to change the Dataguard ...

PL/SQL binding operations fall into these categories: For in-binds and out-binds, bulk SQL uses bulk binding; that is, it binds an entire collection of values at once. For a collection of n elements, bulk SQL uses a single operation to perform the equivalent of n SELECT INTO or DML st...
If you’ve read the linked article you’ll see how Oracle’s sampling strategy has changed in recent years, so a check that will be relevant to some of your indexes is whether or not the average rows returned is equivalent to roughly 1,140 leaf blocks. Other simple checks that might be...
