I tried to change the process using SQL> alter system set processes=300 scope=spfile; and got the msg that system altered but still the error persisit. I reffered to a link RCU-6107, RCU-6092 for the same here it is mentioned in one ofthe post that some user has changed it manually ion init.ora file... Changing manually or through cmd ....

Database version: 10.2.0.4 Patch 45 on Windows 2003
1. Documentation says to set "_first_spare_parameter" to resolve bug 6904068. What should be the value if we actually see this bug occurring after applying the patch. How can we determine that we need this parameter to be turned on?
2. How can we determine we need to set "_third_spare_parameter"? How can we check if there is a regression on log files?

The following is the Record type and table type created. It is called in the below procedure. The procedure will be called in another procedure to return the records. But the count is showing as 0. How I get an OUT param with records which I can use in the calling procedure.
-- Record type
type t_ein_cmpl_rec IS RECORD(
IN_req_param_id t_IN_req_param_id,
IN_call_request_id t_IN_call_request_id,

I am adding a parameter to the parameter form of existing reports based on a select statement and has two columns. That part is fine. However, Oracle reports is adding a dash between the two values. Still fine, but I am also adding a UNION with ALL in case the user wants to run the report for all values. In the Parameter form it looks like this:
ALL -
RBC - 111
RRG - 234
TEB - 445
How do I get rid of the dash for "ALL" since I did not physically add it? Below is my select statement for the parameter I created:
SELECT code,
code_num
FROM codes
WHERE code_num <> 0
UNION
SELECT 'ALL', ' '
FROM dual
ORDER BY 1;

How oracle deals with the setting of init.ora parameter compatible.
e.g. we have
DB Version=10.2.0.4
compatible=10.2.0
what is the possible leak for us ? Is there any description about the features changed in 10.2 up to 10.2.0.4 in all steps - so that we can check out which functions we do not have.

In the program i wrote, posted in this thread I parallelize 340 jobs.
To do this, according to oracle documentation, i set the job_queue_processes parameters to 450. This works fine, all jobs are submitted, but, when i chek the dba_scheduler_job_run_details, i notice that there is a difference between REQ_START_DATE, which is my requested start date, when i enabled my job, and the ACTUAL_START_DATE, which is the date on which Oracle start this process.
And the more i submit job, the more difference between ACTUAL_START_DATE and REQ_START_DATE increase. But for each job, run duration is less than 1second. I check the processes parameter, and it is set to 100. if i have to increase the processes parameter to 450 too ?

In PL\SQL program, I am writing information from one table to file. In my current architecture, I am writing the information to approximately 1000 files.
If I put the database write operation in another package and in another method and call this method from my PL\SQL program asychronously, can that increase performance?

Is there any way to tell what processes/sessions were connected to a DB after I get an ORA 20error. As you can see from the query results below, I did hit the max value of processes but I would like to know when it happen and who was connected.
I realize I can up the value, but before I do that I want to see what caused this to happen.
SQL> select * from v$resource_limit where resource_name in ('sessions', 'processes');
RESOURCE_NAME CURRENT_UTILIZATION MAX_UTILIZATION INITIAL_AL

processes 221 1000 1000

i got this error..
ORA-00020: maximum number of processes (1100) exceeded
my oracle version is 10.2.0.2.0
when i was trying to login to oracle i got :ERROR at line 1: ORA-01012: not logged on
lucky i was having another sqlplus login ..
wht i should do to bring the number of process down without increasing the process value and shuting/restaring down db.
"Usually, when this happens, I want to get connected to the instance, so that I can try to figure out which user is causing the problem. One way to do that is to use the 'ps' command to identify some of the oldest server processes, and kill the 3-5 oldest processes, and then quickly try connecting to the database. Once you're in, you can look at things like V$SESSION to try and determine which user(s) is (are) consuming so many connections, and then go from there."
this is what i got from [URL]....
1.if i am giving ps -ef in OS it will give lot of detail ...
2. in v$session wht i should look for ....

I don't know if there is a beginner forum out there for PL SQL, but I cannot find one.I just started taking an Intermediate Oracle course to learn PL SQL. Today is my first day and I just installed Oracle 11g. I was in SQL Plus, tried the edit command. I got the message "wrote file Afiedt.buf" and then it was just a flashing cursor in the line below. I could not type any commands. I just hit the X to close the program.
What could I have done to exit the program with that flashing cursor since I was unable to type anything?

I am using Oracle 11g R2. (11.2.0.3)
I know that in the profiles of the user I can set limit for the number of sessions per database user, using the below command:
alter profile <profile_name> limit sessions_per_user=<required_number>;
I need to set maximum number of processes for the application user so in case they opened too many number of processes on the database they do not block the automated jobs to be run.My questions:
1. set a limit on sessions_per_user is it the same as a limit on processes? 1 proccess= 1 session ? Is there any way to limit the number of processes (not sessions) for a database user?
2. I am using RAC so the number of sessions is per the whole database, while the max number of processes is by instance (not database), so even I set a limit on the number of sessions (above the limit of processes for one of the instances) one instance may face ORA-20 errors, while the max number of sessions did not hit the limit. is there any workaround for this case?

We are currently using OCI to connect to Oracle DB using c language. Each process has its own dedicated Connection and Env handle, session handle ...
Right now we decided to use Connection Pooling. In the documentation , Connection pooling examples were using multi-threaded environment. But in our case its multi-process system and we cant modify products architecture to multi-thread.
I would like to know how we can use Connection Pooling on multiple processes.

oracle 11.2.0.3 I have insert only tables that receive srecords from multiple processes at a rate of about 200/second. Each transaction can have up to 100 records. I have another set of processes that queries this table for the latest data. These processes run anywhere from once a minute to once an hour. Processes do not get all of the data. They get data based on a type field.
Both of these are from java middle tiers. The process that queries data (The subscriber) does so at the request of many remote servers (there will be vast numbers). I am not allowed to expose these downstream databases to the internet (they are not oracle DBs anyway) so I cannot use streams or golden gate
So basicallyInsert Process: multiple sessions that combined insert records up to 200/second. There will be between 1-100 records per commit.
Query Process: Downtream process makes a request to my middle tier. This middle tier runs a query to get the latest data and passes it back. This design is set and I cannot change it.
1. right now we capture the insert time of the record. However, at this rate of inserts some processes will commit faster than others. So I cant use a 'greater than my insert time' query.
2. streams/golden gate won't work. can't register these DBs.
3. don't want to serialize my inserts because since I am not sure I can keep up with the insert rate. I don't even know what the specs will be for the production hardware. I have to actually deliver this before its decided. So I am being conservative.
4. I really want to avoid updates on this table if possible. In part due to my limited ability to test.
5. due to the number of downstream processes it is possible that it will request data and for some reason fail to insert the data locally. So the downstream application will keep track of the latest data it received. This means that a subscriber may need to request the same data again.
Is there a way to set up change data capture with multiple subscribers to handle this? if my subscribers are just queries? All the queries come from the same servers(there will be several, but all the same thing). If so, when I performance test this are there any wait issues I should keep an eye on?

Getting starting with diving deeper into APEX and reading the developers guide all 800 pages of it! Thing is I'd like to get started with some of the more interesting stuff.
I have created a form page based on the "Form on a Table with Report". The report part looks fine. What I'd like to do now is use an API I've built to change how the insert and update works. So when the submit button is pressed it rather performs an API call to the procedure/function.
1. Should the API be a function or procedure. In my playing around I saw that a procedure might work better or easier to implement
2. How would I go about creating a call for the button to use instead of the current processes?

Oracle 11g R2 on WIndows 20o8 R2 Standard edition
I have a test server that keeps running into ORA-00020: maximum number of processes error each night. Our current setting is '600' processes to be allowed. There are no users to this database except myself. No front end app connects to it either.
I found that ORACLE.EXE (SHAD) process coming from SYSMAN user is the one eating up all the processes and eventually causing that error.
From v$session, the program is OMS.
From v$process, the hostname is the server itself.
I narrowed it down to restarting the ConsoleService, if i do that, then the number of processes drops down. So now im not sure why something within the ConsoleService is logging in, taking a process and not releasing it...What i can check?

We have an application that has "After Submit" and AJAX "On-Demand" processes. We need the "After Submit" to fire and complete first, set an application item (by referencing the next value in a sequence), and then fire the "On-Demand" processes. We have the sequence number set accordingly, with all of the "After Submit" processes given a lower (APEX) sequence number than the "On-Demand" processes; however, it seems the "After Submit" processes are still not firing and completing because only intermittently are the "On-Demand" processes able to access the application item's value--80% of the time this value is simply blank. Making matters more complicated is that the application item is derived from an Oracle sequence, so in my "On-Demand" processes, I cannot simply re-run some of the same logic used in one of the "After Submit" processes that sets the sequence--the sequence may only be set once, and only by this "After Submit" process; we have no choice in that regard. Is there any way possible in APEX to 100% force processes to fire AND complete, one after another, in the order in which they are listed by their (APEX) sequence? In other words, if we have this:
(APEX) Seq Name & Process Type
1 process A ("After Submit")
2 process B ("After Submit")--this sets application item :XYZ
3 process C ("On-Demand)--this uses application item :XYZ and MUST have this item value available to do any processing Can we instruct APEX to fire process A, complete it, fire process B, complete it, and only then, fire process C?
