Increase INI_TRANS for heavily logging tables

if the tables are transaction intensive like used for logging then increase ini_trans from default upto 4 or as you deem correct.

verify ini_trans using the below query
select table_name,ini_trans,freelists,freelist_groups from dba_tables
where owner='SIEBEL' AND TABLE_NAME IN
(
'S_DOCK_TXN_LOG')
