Why is 1 second as shown in PLAN not fast enough?

No Blackswan,

View performance is not good and execution time is approx 5 mins for single record.

Since NOBODY can optimize SQL just by looking at it, we need a few more details.
http://www.orafaq.com/forum/mv/msg/84315/433888/#msg_433888
Please refer to URL above & be sure to provide the details requested:
1) DDL for all tables & indexes
2) EXPLAIN PLAN
3) output from SQL_TRACE & tkprof

It might help if actually posted the query, you know. However, this looks pretty odd:

  34 |       UNION-ALL                          |                                |       |       |            |          |
|* 35 |        TABLE ACCESS STORAGE FULL         | IPTV_PRDCT_PARAM_FILE_TVPSE00  |     4 |    24 |    12   (0)| 00:00:01 |
|* 36 |        TABLE ACCESS STORAGE FULL         | IPTV_PRDCT_PARAM_FILE_TVPSE00  |     4 |     8 |    12   (0)| 00:00:01 |
|* 37 |        TABLE ACCESS STORAGE FULL         | IPTV_PRDCT_PARAM_FILE_TVPSE00  |     4 |     8 |    12   (0)| 00:00:01 |
|* 38 |        TABLE ACCESS STORAGE FULL         | IPTV_PRDCT_PARAM_FILE_TVPSE00  |     4 |     8 |    12   (0)| 00:00:01 |
|* 39 |        TABLE ACCESS STORAGE FULL         | IPTV_PRDCT_PARAM_FILE_TVPSE00  |     4 |     8 |    12   (0)| 00:00:01 |

Looking at the predicates:
  35 - filter(TRIM("PRODUCT_ID_S_E_OF_STB1")=:B1)
  36 - filter(TRIM("PRODUCT_ID_S_E_OF_STB2")=:B1)
  37 - filter(TRIM("PRODUCT_ID_S_E_OF_STB3")=:B1)
  38 - filter(TRIM("PRODUCT_ID_S_E_OF_STB4")=:B1)
  39 - filter(TRIM("PRODUCT_ID_S_E_OF_STB5")=:B1)

you are scanning that table five times, when once would do.

Dear John,
As per your suggestion.I checked that part but not getting any performance issue.As per our analysis,We are getting performance issue because we have used function in .sql query:
