ebs: Gather Statistics

In R11i/R12 customers should be using the FND_STATS command.

Do not use the ANALYZE command or DBMS_STATS package directly,

as doing so may cause incomplete statistics to be generated.

Use the following command to gather schema statistics:

   exec fnd_stats.gather_schema_statistics('ONT') < For a specific schema >
   exec fnd_stats.gather_schema_statistics('ALL') < For all schemas >

Use the following command for gathering statistics on a temporary table
(ie: temporary tablename = TEMP_tmp in schema ABC):
   exec fnd_stats.gather_table_stats('ABC','TEMP_tmp');
