           INDEX(T2 I0_ESTRUTURA_COMERCIAL)  */
        T2.CD_TIPO_ESTRUTURA_COMERCIAL,
        T2.CD_ESTRUTURA_COMERCIAL,
        T2.CD_GERENCIA_VENDA
FROM  T_PS_COMPL_ESTRUT_COMERCIAL T1,
       T_ESTRUTURA_COMERCIAL       T2
  WHERE  T1.CD_TIPO_ESTRUTURA_COMERCIAL = T2.CD_TIPO_ESTRUTURA_COMERCIAL
  AND   T1.CD_ESTRUTURA_COMERCIAL = T2.CD_ESTRUTURA_COMERCIAL

  HASH JOIN               73     534     27768     71          1
   MAT_VIEW ACCESS BY INDEX ROWID     SISESTAT     M_ESTRUTURA_COMERCIAL_CAD     69     1685     23590     68     SEL$F5BB74E1     1
    INDEX FULL SCAN     SISESTAT     I0_ESTRUTURA_COMERCIAL     10     3370          10     SEL$F5BB74E1     1
   REMOTE          T_PS_COMPL_ESTRUT_COMERCIAL     3     1069     40622     3     SEL$F5BB74E1     1

Answer 1

Maybe I'm missing something but this:
INDEX FULL SCAN     SISESTAT     I0_ESTRUTURA_COMERCIALindicates that one of those indexes is being used.
This:
T_ESTRUTURA_COMERCIALIs nowhere to be found in your Explain Plan. It appears that either you have posted the wrong plan
or Oracle is doing a query rewrite to a materialized view.
