当我尝试备份我的 oracle 数据库时,出现以下错误。
UDE-04031: operation generated ORACLE error 4031
ORA-04031: unable to allocate 16 bytes of shared memory ("shared pool","SELECT j
ob_id FROM v$datapum...","SQLA","tmp")
ORA-06512: at "SYS.KUPV$FT_INT", line 2904
ORA-06512: at "SYS.KUPC$QUE_INT", line 572
ORA-25254: time-out in LISTEN while waiting for a message

ORA-06512: at "SYS.DBMS_DATAPUMP", line 4551

我该如何解决这个问题?
