RE: SQL Query causing "gc buffer busy " or Not ?

That would depend to a large extent on whether the block(s) in which the
desired row appears are the same block(s) the other instances are inserting
into and whether the predicate columns (and possibly selected column(s)) are
in a branch of an index with blocks being modified by the inserts.

So it could, but I can't predict whether it will significantly from the
facts in evidence.

Folks

If the following SQL is Running ONLY on 1 Node & NOT on Other RAC Nodes,
will it contribute to ""gc buffer busy" wait on that Node?

NOTE - However INSERTs happen concurrently to SOD Table from the Other RAC
Nodes too using Other SQLs

Cheers

Vivek

P.S.

SELECT field1  FROM SOD
WHERE  TABLE_ABBR =  :1
and  TABLE_KEY =  :2
and  CONTEXT_SOLID =  :3
