Hi ,

We have a table which has 168900 records and my load check service_disruption_number and if found then delete else it insert the records.

I have observe that delete take lots of time and insert is very fast. first i delete all those records and then i run the insert command.

SGA is 1gb set to target at parameter for balancing.

Please suggect best method to delete fast.
A lot of code here
table structure as below

Use MERGE statement.
However, given the number of bitmap indexes you have it will be slow.
Bitmap indexes are for read-only tables not for OLTP ones.
Often, it is faster to invalidate all indexes and rebuild them afterwards.
