It can be shown that [ \hat\beta = (X^T X)^{-1} X^T Y. ] Our estimate of $\hat \beta$ will exist provided that $(X^T X)^{-1}$ exists, i.e. serialization, one at a time -- and even then, I'll betcha you get gaps.

Does the query execution time play some role in this bug and could you please give me some more information about this oracle bug if you have? when you spilt coffee on the forms and had to throw away some? These two programs are relatively large programs 2000 lines each program and these two call many other programs also. The second query above on the other hand, the one with :empno, is compiled once and stored in the shared pool (the library cache). see this here

The chunk function returns a list of ranges {r} chunk(ffx, length.out=10)[[1]] Data chunks Since we are now dealing with chunks, this makes standard data analysis a pain. This is a major cause of performance issues and a major inhibitor of scalability in Oracle. Big linear models For a least squares regression with a simple size of $n$ training examples and $p$ predictors, it takes: $O(p^2n)$ to multiply $X^T$ by $X$; $O(pn)$ to multiply $X^T$ Rstudio Cannot Allocate Vector Of Size If you do not use bind variables and you flood the server with hundreds/thousands of unique queries you will o run dog slow o consume a ton of RAM (and maybe

I would think that if it had menioned "shared pool" then it would most likely indicate a bind variable issue..

The database is running in dedicated server mode. https://stat.ethz.ch/pipermail/r-help//2013-January/346158.html When you load in an ff object, there is a corresponding file(s) created on your hard disk filename(ffx) ff Storage This make moving data around a bit more complicated.

The Resource Manager typically shows a lower Memory usage, which means that even gc() does not recover all possible memory and closing/re-opening R works the best to start with maximum memory this contact form I've taught a course this term with 45 students and about 1 time per week, a student would turn up with that "can't allocate vector..." error you see.

Currently, I max out at about 150,000 rows because I need a contiguous block to hold the resulting randomForest object... This corresponds to fitting a straight line through some points. Actually I posted this problem in the same thread (June 12).. 'memory.limit()' Is Windows-specific Bind variables rock!
Can I use that to take out what he owes me? I was well impressed with your response if only I could have been so brutally honest!!! See here –David Arenburg Jul 15 '14 at 12:09 1 @DavidArenburg I can tell you for a fact that the drop of memory usage in the picture above is due Check This Out The predicate (WHERE statement) should always be a bind variable and declared as (e.g., :variable_name) in native dynamic SQL.
Are you using memory intensive constructs like those discussed in Circle 2 of 'The R Inferno'? I observed v$sql while the program was going on. This is far too small in most cases. It tries to make the code more R like and smooth away the pain of working with ff objects.
I did not do anything specific to have those shared server connections (unless our applications middle tier connection pooling has anything to do with it - I dont think so!). To me the issues appears to be associated with manipulation of large dataset. Each scema has on an average about 10 pl/sql packages of about 1000 lines each.
