kevin closson’s oracle blog: platform, storage & clustering topics related to oracle databases

kevin closson’s oracle blog: platform, storage & clustering topics related to oracle databases kevin closson’s oracle blog: platform, storage & clustering topics related to oracle databases oracle-related platform, storage and clustering topics (with the occasional rant) blog about appearances/contact papers, etc index of my posts off topic: peave of the day == the fax machine. published november 9th, 2007 oracle 3 comments instead of fax communication, why don’t organizations just ask for 80 column punch cards or cuneiform on papyrus reed? these days i get so agitated when, say, a customer service department requires a fax to clear up an issue. does anyone else feel the way i do, or am i just (un?)characteristically crabby this morning? instead of wandering around looking for a fax machine, i thought i’d email the following reasonable anti-fax position to see where it would get me: regarding […customer service issue…], do you really want a fax? anymore that is becoming so outdated. how about a scanned pdf emailed? that would surely take the same amount of human resources (perhaps less since you wont be changing paper), cuts down on filing space, saves trees and keeps me from trying to find a  fax machine. and their brilliant reply? of course: regarding your inquiry, the preferred methods of documentation submission are via postal mail [or] fax to our office at […] doesn’t it stand to reason i already knew their preferred method? oh, hold it, there is new information there after all: i can simply stuff it in an envelope and snail mail it. brilliant! a recommended blog: christian bilien. published november 8th, 2007 oracle 1 comment i’d like to recommend christian bilien’s blog. he covers solaris and san-related topics (and more) that pertain to oracle very, very nicely. one more for the blog roll. oracle11g automatic memory management part iii. automatically automatic? published november 8th, 2007 automatic memory management , oracle11g 0 comments oracle database 11g automatic memory management is not automatic. let me explain. the theory (my interpretation) behind such features as amm is that omission of the relevant initialization parameters for the feature constitutes an implied disabling of the feature. i’m sure many of you are going to think i’m stupid for not knowing this, and indeed it is likely documented in bold 14 pitch font somewhere, but unless you set memory_target you don’t get amm. i sort of presumed it would be the other way around. here is a simple example. i have a minimal init.ora and am running catalog.sql and catproc.sql only to hit an ora-04031. here is the init.ora: control_files=("+sdata/test/cntltest.dbf") undo_management=auto db_block_size = 8192 db_files = 300 processes = 100 db_name = test and, here is the ora-04031: sql> grant select on ku$_fhtable_view to public 2 / grant select on ku$_fhtable_view to public * error at line 1: ora-00604: error occurred at recursive sql level 1 ora-04031: unable to allocate 1044 bytes of shared memory ("shared pool","select value$ from sys.props...","typecheck","kggfadokghalloc:1") and here is all i had to add to the init.ora to fix it: control_files=("+sdata/test/cntltest.dbf") undo_management=auto db_block_size = 8192 db_files = 300 processes = 100 db_name = test memory_target=1500m memory_max_target=1500m as i pointed out in my blog entry entitled oracle11g  automatic memory management part ii - automatically stupid?, i have been pleasantly surprised by amm in 11g. i suppose this simple catalog.sql/catproc.sql example is another-albeit very simplistic-example. blog a lot, or blog not. i’m not dead. published november 7th, 2007 oracle 4 comments well, it’s official. i am a completely delinquent blogger. it isn’t that i don’t have a lot of stuff to blog about, because i do. i just don’t know what is “safe” to blog about. i’m still trying to get a feel for things. i’ve taken a role as a performance architect in oracle’s systems technology group, which is a division of the database server technologies organization. i’m working on future products that i cannot talk about whatsoever. that is proving to be a bit of a bummer. even if i blog about some of the lower-level stuff i’m seeing that is platform generic, it would still tip folks off on the sorts of things we are doing on this project, so as they say, “mums the word.” i know there are all sorts of folks i’ve wanted to meet up with at oow. send me an email at ora_kclosson at yahoo dot com , ok? i do have a linux block layer i/o related blog entry that is just about ready. i’ll do my best. oracle database 11g (11.1.0.6) for x86_64 published october 18th, 2007 oracle 1 comment oops, there was a false alarm about the availability of oracle database 11g (11.1.0.6) for x86_64 (amd/em64t). i just checked and it is now downloadable on otn. next page » disclaimer the views expressed on this blog are my own and do not necessarily reflect the views of oracle. the views and opinions expressed by visitors on this blog are theirs, not mine. pages about appearances/contact index of my posts fs, cfs, nfs, asm topics general performance and i/o topics miscellaneous oracle on opteron, k8l, numa, etc oracle11g topics real application clusters related topics papers, etc recent posts off topic: peave of the day == the fax machine. a recommended blog: christian bilien. oracle11g automatic memory management part iii. automatically automatic?
