Oracle Version 8.1.7

We are getting following error:
ORA-04031: unable to allocate 4096 bytes of shared memory ("shared pool","begin :1 := dbms_lob.getLeng...","PL/SQL MPCODE","BAMIMA: Bam Buffer")

We have used CLOB and BLOB columns in tables and we are fetching the data using JDBC 2.0.

We have set the shared_pool_size = 30728640 and
shared_pool_reserved_size = 1572864

Please let me know the cause of the problem and how to fix it.

try to check java_pool_size and increase shared_pool_size.
sizing SGA depends on available memory

definetly its problem of SGA so increase the size.
