I have noticed that a profile (created by Sqltune) which has been utilized by Oracle for some time suddenly stopped being used- When I disabled and than enabled the identical profile Oracle resumed using it.“MIXED_PAGE_ALLOCATION OFF

ORA-03001: unimplemented function Try out it without the bulk obtain line and find out what comes about. What Variation are you presently on by the way?
SQL Server 2016 introduces adaptive spinlock scope (While Microsoft likely has another, cooler name for it). When a world or NUMA node stage spinlock useful resource is deemed contended, the scope is mechanically promoted.
The exterior stage defines how Each and every team of conclude-people sees the Business of knowledge while in the database. Just one database may have any variety of sights for the external level.
A database model is a kind of information model that decides the sensible construction of the database and essentially decides where fashion details might be stored, arranged, and manipulated.
“I've to confess that I have improved my brain about Outlines genuinely owning a chance to wholly lock a prepare by the way. I believe that attempting to Restrict the optimizer to buying an individual plan with hints is often a challenging undertaking at most effective.
A few months ago I came up by having an strategy / wish which I now realized may be doable without having A great deal engineering on my section. My contemplating was that It might be wonderful if oracle stored from the historic performance on queries (which I now recognized it does for maybe ten times in dba_hist_sqlstat, dba_hist_sqlplan and dba_hist_sqltext ) making sure that just after an up grade (or optimizer parameter improve) we could contend with the sql that's not performing very well and see the way it did before.
Trace flags are Particular switches that, once you you can try here flip them, allow different behaviors within your SQL Server. Again during the SQL Server 2000-2005 times, these were Tremendous-rare undocumented tips which were handed out by Microsoft aid to repair uncommon instances.
In the command prompt, sort netstat -n -a. The -n switch instructs netstat to numerically display the handle and port range of Lively TCP connections. The -a swap instructs netstat to Exhibit the TCP and UDP ports on which the computer is listening.
So i have this SQL_ID that has been managing wonderful and recently shopper started out complaining regarding the slowness. so i went in to examine the transform of explain prepare and turns out the make clear strategy hasn’t transformed, even so the corresponding avg_etime has spiked poorly (avg_lio also).
Thank you over and over more than for your code! It’s helped us include hints to not merely errant SQL that we will hint to the fly and confirm the functionality right before investing the months of paperwork and regression screening for a code alter.
Another approach to hardware assistance for database administration was ICL's CAFS accelerator, a hardware disk controller with programmable lookup abilities. In the long run, these initiatives had been normally unsuccessful since specialized database machines couldn't preserve pace Together with the immediate progress and progress of normal-reason computer systems.
