Change the version a try, even if sweep out what the underlying reveal that you are not processing, and customer communication or later add some validation best remedy

Looking for ORACLE technical support?
Or to send the problem to see ITPUB

CodePudding user response:

Don't understand this, don't know whether I like this kind of high-level language c # has destroyed object syntax;

CodePudding user response:

Player, but this thing is not the same as the standard, as defined in the open a sr to ask, who know how oracle can give a reply,

Is worth learning, continuous attention

Are you sure is a memory leak (100 times call 100 long memory, call 10000 long 10000 times), and not like the buffer function of the connection pool?
