Re: init.ora processes ??
Another thing to consider is this: From OraPerf: The LGWR needs to scan all processes to find each process that is waiting for the commit to be written. So when you have an excess of process LGWR works harder.

RE: init.ora processes ??
For each process 'reserved' by oracle, there is a small amount of space allocated in the SGA and a semaphore is reserved at the O/S level (assuming UNIX).

Re: init.ora processes ??
the larger the number of processes in the init.ora, the larger the number of semaphores you need on most Unix systems. Not all, I *think* from reading the list that AIX doesn't use semaphores (I've only worked on HP-UX and SUN, both of which use semaphores) If the processes parameter is set so high that there are no more semaphores available, your database won't open --- Bob Robert [EMAIL PROTECTED] wrote: All, What is the impact of processes init.ora parameter other than restricting number of user sessions ?

Re: Init.ora and Config.ora
I always thought it was for separating instance-specific parameters from database-specific parameters in an OPS environment. At least, that's one place where it is very useful to have separate files. Of course, it was a matter of style whether "config.ora" was the database-level one or vice-versa... Also, somewhere back in the mists of time, any ".ora" file for initialization parameters had to be less than 10,000 characters in size; anything beyond that boundary was simply not used(I kid you not!). So, having multiple files related by "ifile=" was the workaround, especially for those neurotic souls who insisted on leaving comments for documentation... - Original Message - From: Fink, Dan To: Multiple recipients of list ORACLE-L Sent: Thursday, June 13, 2002 10:48 AM Subject: Init.ora and Config.ora Beware...DBA heresy below...

RE: Init.ora and Config.ora
Dan, I agree with Rachel. I have one init.ora file for each database instance. I personally *HATE* the "ifile" business. All that it does is make me go searching in another directory to see what the parameters are set to. I like to go to one directory/one file to set/review my init params. I can see everything in one place, and I don't have to go searching/remembering where things are. I also keep this file in the ORACLE_HOME/dbs or database directory (depending on OS). Frig the pfile directory. Another lousy idea from somebody. hope this helps.

Re: Init.ora Compabible Setting
Well, if you are using any functionality related to 8.1.0 then leave it as it is.. or atleast boost it up to 8.1.5 or 8.1.6 .. This will enable your DROP COLUMN too.. As might have been suggested..

RE: Re: init.ora
Rood: Not exactly correct. The ifile parameter will tell you all the files included in the init.ora via this method. However, it will not necessarily give you the location of the init.ora itself. Now, on a Windows NT system, this is how Oracle is able to keep the init.ora in the %ORACLE_ADMIN%\%ORACLE_SID%\pfile directory and still have a link to it in the %ORACLE_HOME%\dbs directory. However, on UNIX, where symlinks are used, there may be no ifile parameter in the init.ora and certainly probably not one pointing to the init.ora itself. Therefore, at best, this parameter is unreliable for finding the init.ora.

The default is 100, but my boss thinks 10 is a better value for Cost based Opmtzr.. doesn't make any sense to me.. why would reducing the cost of using an optimizer make it more CBO or go faster.. what if its a large table? Is it a good strategy to reduce this value to 10 or so .. any one played with this on a 30GB database ? or any other size db? thanks, Bruce -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: INET: [EMAIL PROTECTED] Fat City Network Services-- (858) 538-5051 FAX: (858) 538-5051 San Diego, California-- Public Internet access / Mailing Lists To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).

Re: Init.ora .. OPTIMIZER parm: optimizer_index_cost_adj
This parameter tells the optimizer how much weight to give to indexes when evaluating a query. That's the short answer, it's really more complicated than that. A client I have uses a value of 4 for this parameter. This was arrived at using the old fashion method of changing the value and running some test queries and capturing timings for them.
