If you want to check whether that statement is using single row processing or
array processing then select executions, and rows_processed from v$sql for the
SQL_ID.
Do it a couple of times over a few minutes and the deltas should allow you to
work out the arraysize (with a little error, possibly).

Subject: Insert running long
Hello
DB Version 11.2.0.4 OS Linux
one of the insert process is running from 6 hours today and getting executed so
many times - Each Execution is roughly taking a sec -
its plain insert -I suspect it is is being done in pl/sql loop row by row
processing -
How can I validate it ? ask for the pl/sql procedure and check the code -
this is the insert query -
INSERT INTO MEMBER_BANK_BAL(MEMBER_BANK_BAL_ID,MEM
BER_BANK_ID,INTERNAL_ACCT_ID,MEMBER_BANK_BAL_AMT,A
CCRUED_INT_AMT,FROM_DT,TO_DT,CREATE_TS,LAST_UPDT_T
S,RT_RECRD_NUM,RT_TIER_BAL,BATCH_JOB_EXECUTION_ID)
VALUES ( :1, :2, :3, :4, :5, :6, :7, :8, :9, :10
, :11, :12)
Wait events:

It seems like db file sequential reads are generating from Index
