We have a change in IT Dept in our organisation and we have been asked us about the impact of the following changes
1. Change in listener Port
2. Change in value of send and Recieve buffer in listener.ora
3. Change in Archive Size from 40M to 20M
i have created a database a make listener configuration and tns with netca.with netca configuration i used port 1525 then i need to change my database port with 1521 so i just moved to my listener.ora and tnsnames.ora and changed port setting to 1521 but after that also my database listening to both the locations.1521 and 1525..if i check connection with sql developer it says connect.how's it possible
View 3 Replies View Related i have a listener configured on default port 1521 and i wanted to change it. i did following:-
1. stop the listener through lsnrctl stop
2.change the port number in tnsnames.ora and listener.ora and save both files.
3.now i start the listener as lsnrctl start
4.it started successfully but saying that it cannot register to instance.
5.i connect sqlplus / as sysdba and execute "Alter system register" and "System Altered"
but even then the listener is not registering.
One of our requirements is to secure the listener and other Oracle services by running them as a local OS account rather than as LocalSystem on the server.
I created a local OS account (assume it's named oracleuser), assigned it to the User and ORA_DBA groups on the server, and then I went to the Local Policies and added oracleuser to "Deny log on locally" and "Log on as a service".
I opened up the Services utility and stopped the four Oracle services we have running (OracleMTSRecoveryService, xxx_home1iSQL*Plus, xxx_home1TNSListener, and OracleServiceMYDB). I changed the "Log on as" for each service to oracleuser with its password (copied and pasted so I know there are no typo's), and restarted the services.
All the services except the listener started up. Attempting to start the listener caused the following error:
"The xxx_home1TNSListener service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service."
I tried rebooting the server and had the same result.For now just the listener service has been switched back to logging in as LocalSystem while the other services continue to use the local OS account and the database seems stable, but I do need to figure this out.
I have installed Oracle 11g XE . After this , i have upgraded to Apex 4.2 All it's working fine, but..... by default XE installs and configure apex to use embebed pl/sql gateway.
In this scenario, the images are stored directly in the database within the oracle XML DB repository. This may be a problem because XE have a 11GB limit and my apex aplication is simple, but it may upload pictures for customers, etc, and in this schenma the pictures will consume space in the database instead consuming in the linux filesystem.Can i install HTTP server in a 11g XE and reconfigure apexr?, or can i change to apache+listener? or more easy....can i upload images outside the XML DB in my apex application easily?
Is there a way of changing the values of sysdate in a session only?
not the formate the actual values
is if the date was 31/12/2003 and i wanted to change it to 31/05/2003
could this be done
We are facing below issue in Oracle forms 10g( Rel 10.1.2.0.2) with Windows XP professional.Application server J2EE 10.1.2.0.2).
We have a multirecords block. After navigating to last record by clicking mouse in scroll bar and change values in a column by clicking mouse in column to change, cursor control is moving to some other record(where cursor is located previously) and current changed value it is showing as not fully validated.
Eg: We have columns like below in multirecords block
Security Price Date Price
--------------- ------ ----
1 1/1/2011 12.00
2 1/1/2011 16.00
3 1/1/2011 18.00
4 1/1/2011 19.00 (Last Record)
If am changing last records price to 20 then press tab key, cursor will be moved to second record and cursor will be highlighted in security 2. column price where we changed to 20 also not validated to show as 20.00 with 2 decimal format mask.Along with this we are getting below error message ' FRM-41008 - Undefined function key, press Ctrl + F1 for list of valid keys.After changing the price we are pressing the tab key only.
This occurs randomnly and when we querying more than 2000 records with multiple times.
I have 2 databases( A and .. which shares common ORACLE_HOME....
i configured 2 listeners through netca in different ports....
and both listener names are different...
But when I stop LISTENER.. both the listeners are getting stop and when i start both the listeners are up and running.. and I could see database B's services.. and vice versa...and when i tnsping , i am able to see port 1521 default port for database A.
when I run I bash, i have included ORACLE_HOME path... so should i add oracle_SID also there..if so, which SID should I add A or B?

Any problem using 4.2's One Level Tabs - Content Frame page where you have a parent region (of type content frame Body Container ) while number of child regions (of type Hide & Show Region - Borderless ), if you want to re-order them by changing the sequence, it has no effect when you run the page.
The regions still show in the same order top to bottom as it did before the update of sequences. Heading links (to show/hide child regons in content frames) has the same ordering as before.
One of my clients need to remove three(of four) CPU to comply the licensing agreement with Oracle.
To avoid problems and also to list the possible problems that removing the CPU can bring, I wish to make a survey of the possible impacts, especially in performance, that removal can cause.
How can I get this information?
I'm trying to find some information on the performance impact of a trigger on a heavily updated table when the condition to fire the update trigger is NOT met. In other words I guess what I'm really trying to find out is what the performance impact of the system checking the condition on the trigger to determine if it should fire or not is.
For example I have a batch job that inserts and updates a table heavily, but the batch job almost never updates the column in question on the trigger to the value that would cause it to fire, but it does update that column to other values often.
I know about the many downsides of using triggers in general, but I'm working with a third party application, so more optimal solutions aren't an option.
in my oracle enterprise manager under " user i/o " .i am having basically four category:
if we rank them out of ten it would be like :
read by other session 2/10
db file scattered read 1/10
direct path read .5/10
db file sequential read 6.5/10
and all these are comming for 2 tables involved for almost all time .some way to handle "read by other session" and " db file sequential read " .
i am rebuilding indexes of these involved table once in 10days and statistics for the these tables are collected every day using "analyze table "xxx" compute statistics."tell me the indepth approach i should take to minimize the impact as users are complaing for performance.
I am attempting to read from the maillog of our server, but I wish to make as few changes as possible for fear of blocking other systems access to the file.
I was initially going to call create directory maillogs as '/var/log/maillog' and then drop directory maillogs; when I was done but I found my user does not have "create any directory" permissions.
Rather than compromise security of the existing database configuration, I thought I would permanently add the maillogs to the list of available data directories. Are there any implications to the filesystem if I do this, or should I be able to add this without consideration of affects.
Understand that I will only be opening the file for (R) READ TEXT access only.
Primarily I am concerned that Oracle (in the background) will keep a file pointer open or something of that nature that would block other programs from writing to the file even after I close the file pointer. I want to make as little impact as possible to the file system.
Which config file is used to change the os version(RHEL 4.0 to RHEL 5.5) by OS admin what will be its impact on ORACLE Databases.

When I checked the status of $emctl status dbconsole. I got this error OC4J Configuration issue.
I was told by the forums to drop and recreate the repos. But I noticed the moment you drop the repos you will loose the passwords of SYSMAN and DBSNMP. emca -deconfig dbcontrol db -repos dropemca -config dbcontrol db -repos createI tried default passwords does not worked. it looks like the only option I have is to reset the passwords. but my main concerns is this impact the DB in generally or its common. or is there any other way we can get the OEM back(I already dropped the repos).
my sql query has three tables in from clause so it has two join conditions and one where condition.
account_no is number data type and v_account_no is varchar2() data type
The where clause is :
"where account_no=to_number(v_account_no)" with this condition in my sql query has the cost 392
we just modify the where clause as where v_account_no=to_char(account_no) with this condition in the sql query has the cost 11.
what is impact of this data type conversion and difference between these two "to_number() and to_char()" in performance wise to reduce the cost of query?
I'd like to call an existing function/procedure from a resource template. For example, I have a procedure called 'rest' with an out parameter of 'p_out' - how do I use this within a resource template?
At the moment I have defined the template as type 'PL/SQL Block' and with the 'GET' defined as:
begin
myschema.rest(:p_out);
end;
APEX_PUBLIC_USER has been granted 'all' on the procedure. The p_out is populated with a piece of text.
When I call this resource, I get a '500 Internal Error' returned. I've tried adding p_out as an X-APEX-FORWARD parameter, but nothing seems to work.
Query-based templates seem to work OK.
Using Listener 1.1.3 with Tomcat6.
I am using oracle 11.2.0 in linux platform.i have created a listener for the asm database. and i am using non default port of 1525 whenever i go for lsnrctl>status always shows for the port 1521. i don't want the default port 1521 and i have changed the local listener as listener1 with port 1525 protool tcp in spfile and registered with the asm database.Is there any option to change the default listener as listener1.
also,everytime when i give lsnrctl>show current_listener it is showing "listener"
i have set the current-listener to listener1 and save_config listener1 and reloaded.After exit and enter lsnrctl>status it will show for port 1521 When i attempt to start listener1 every time. it will prompt listener1 is already running.
I have been used to the consciousness that we should use the minimum length for varchar2 field that can store the data we need manipulate. But recently I was told that it has little impact on performance if we assign a much longer size.
View 13 Replies View RelatedAny impact is there if is do the following:
ALTER TABLE MY_TABLE TRUNCATE PARTITION P1 UPDATE GLOBAL INDEXES;
will there be any lock on the table during this operation? DML operations will work without any issue or not?
In one of our RAC envrionment, we have more than 15 databases in a server running in AIX Operating system.the Listener file I am able to find only one entry (SID). But while trying to execute lsnrctl status it displays all the 15 SIDs in the list hosted in the ser ver. Not sure how it works?
As we created another one new database in the database, where i need to add this SID in the listener.ora file to reload the listener.
I am looking at a performance issue at the moment and trying to replicate on a test system. I am initially looking at the impact of upto-date statistics on the main schema's objects.
For this I wanted to:
first run the batch with whatever stats were present in the database Flashback the db to before the batch . Gather stats Re-run the batch with updated stats and compare results.
However, I inadvertently ran the stats job before running the load the first time! I have the SCN from when the environment was set up like production (ie before the stats were run) so am I correct in saying that if I flashback to this point then the stats will be "old" and I can just run the batch then? I know I can verify this when I Flashback the database by looking at LAST_ANALYZED on tables etc but it would be good to know this before hand as it's a 12 hour batch.
I am using Oracle 9i and Unix on my system and trying to execute a UNIX shell command through external procedure in C.I created a shared lib (libextproc.so) for the following function.
int sysrun(char *command)
{
return system(command);
}
This function runs fine when caled through a driver function in C, meaning that the shared lib is fine.In PL/SQL, I have used the following method to invoke a UNIX command:-
create or replace library shell_lib as '/home/ECETRAonsite/oracle/OraHome1/lib/libextproc.so';
/
create or replace function sysrun (syscomm in varchar2)
return binary_integer
as language C
name "sysrun"
library shell_lib
parameters(syscomm string);
/
Now when I call this PL/SQL function to invoke the command, it is run succesfully but does not create the file.

We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.
The APEX listener appears to be more than just a Java PL/SQL gateway.
Is there a minimum version of APEX the APEX Listener supports?
I am using prebuilt MV to perform replication of about 300-400 master tables from one database to another database. I am wondering about the impacts on triggers in general replication.
IS there a general rule to enable/disable a trigger before a refresh.
I used Region, Process by to search the report which appears as shown above. Then I use Choose Auditors column to select my Auditor and copy paste it into the report under To be Audited By col. Is there a way to automate the process. I am here using a tabular form in APEX. My main aim is to assign auditors based on Region, not equal to Processed by.

My scenario is to insert values into 'out' column by comparing 's' and 'IP' columns of temp table.The exact situation is at first need to go to ip column,take a value and then go to source column and check for the same value of ip which is taken previously.Then after corresponding ip of that source column should be inserted back in previous source column.
The situation is marked clearly in file which i am attaching with '--' comments at respective places.I am also pasting the code which i tried out,unfortunately it is giving error as exact fetch returns more than requested number of rows since there are duplicates in the table.I tried it using nested for loops.Also implemented using rowid,but it didnt work.
fixing the errors or if there is any new logic that can be implemented.
