hi,
I tried to export my instance oracle:

EXP SYSTEM/MANAGER@MYDB FULL=Y FILE=C:\MYDB\EXP.DMP LOG=C:\MYDB\ERROR_EXP.LOG


but I get this error:

xporting table WYTYPE 0 rows exported
. exporting referential integrity constraints
. exporting synonyms
EXP-00008: ORACLE error 4031 encountered
ORA-04031: unable to allocate 4032 bytes of shared memory ("large pool","unknown object","joxu heap init","ioc_allocate_pal")
EXP-00000: Export terminated unsuccessfully


How can I resolve this problem??

Thanks in advance!
