event 10261 and pga
event 10261 可以作为临时处理ora-4030错误的一个手段
[oracle@node1 bdump]$ oerr ora 10261
10261, 00000, "Limit the size of the PGA heap"
// *Cause: the limit is one kilobyte times the level of the event. If the

alter system set events '600 trace name heapdump level 0x20000001';

alter system set events '10261 trace name heapdump level 0x20000001';
