SQL*Loader-926, ORA-04031 unable to allocate x bytes of shared memory

A customer received this error while importing serveral files. The import routine (VB.NET) is using SQL*Loader (Release 11.2.0.3.0) via Process on each table separately (64 in total) and is called weekly for many years now. Last week following error was thrown: value used for ROWS parameter changed from 1024 to 795 (all tables are imported with ROWS=1024, no BINDARRAY parameter specified) > SQL*Loader-926: OCI error while executing delete/truncate (due to > REPLACE/TRUNCATE keyword) for table x ORA-04031: unable to allocate > 4160 bytes of shared memory ("shared pool","unknown object","sga > heap(1,0)","modification ") I'd googled the ORA-4031 and determined the current memory informations: - 3,08 GB (shared pool) (select sum(bytes), pool from v$sgastat GROUP BY pool), - 922MB free memory (select * from v$sgastat where name = 'free memory';) and - 1,18 GB shareable memory (select sum(SHARABLE_MEM) from v$db_object_cache;) To resolve the issue several posts pointed out to look at the views v$SGA_TARGET, v$PGA_TARGET, v$SGA_TARGET_ADVICE, v$PGA_TARGET_ADVICE, v$SGA_DYNAMIC_COMPONENTS and so on, but i have no dba privilege. (table or view does not exist). Thus i'd like to know whether i can resolve the issue only with SQL*Loader settings or must a DBA investigate into this?
