How to use "csscan" on RAC 10g environment

Hi all,
I have a 10g RAC database whose character set is US7ASCII, and needs to converted to WE8ISO8859P1.
I need to run "CSSCAN" to get the information regarding possible issues for this charset conversion.
Per Oracle Doc, cluster_database should be set to FALSE before running CSSCAN & CSALTER.
For the time being, I only need to run CSSCAN to analyze charset convertion factivility (I will not
run CSALTER).
My concern is if the setting of cluster_database=false and the bounce of the instances can be avoided
having into account that I will not run CSALTER.
I will aprecciate your replies.
thanks
Gustavo

CSALTER is the one who demands cluster_database=false, so you can use CSSCAN without setting this parameter.

How to use JMS in a J2EE environment

Hello all,
I would like to find out how to use JMS in a J2EE environment. I use Borland Enterprise Server. Do I need to buy a message software to use JMS? How to use JMS with Message Driven bean?
Thanks a lot.
Best regards
Susan

If you don't want to buy you could try OpenJMS, a free JMS product (http://openjms.sourceforge.net/)
As for learning how to use JMS w/ MDBs, I would suggest grabbing a book on JMS. I found the OReilly book on JMS to be pretty helpful for me.

How to use connection pools in production environment

Hai
We are using Statless Session beans which will call bean managed entity beans
as a developer we completed the first phase of our project successful but when
comming to the production environment they(Higher authoritites of the company)
are asking abt the connection pools. Suppose if my wlserver5.1 has 100 hits per
a second how many connection pools i need to put in the production envirornment
and also is it the right way to increase the connectionpools depends upon the
clients hits????. Can anybody help me regarding this It is very urgent for us.
Cheers Kiran Nallam

Hi Aravind,
It can be used only for calculation kinda "minimum size".
Nothing can prevent a developer from writing something
like this:
Connection con1 = ds.getConnection();
Connection con2 = ds.getConnection();
Connection con3 = ds.getConnection();

You can fix the size of the weblogic connection pool depending on yourexecute
thread count value. For example the default value of execute thread countvalue
is 15. So at a given point of time you cannot use more then 15 databaseconnection.
Database connection pool size should be equal to or less then the size ofexecute
thread count
"Slava Imeshev" <[email protected]> wrote:
Hi Kiran,
It's hard to provide exact dependence between number of hits
and actual number of consumed connections because it's a highly
variable distributed environment. But the general approach is
simple - before rolling out your application, make sure you
tested it under simulated peak load. Your connection pool should
have enough connections to serve peak load. Without such a testing
you will never know whether your app scales or not.

How to use TABLE_FROM_BLOCK in forms 10g ??????

i have use the procedure below code in when-validate of a database item in forms6i its working fine ,but the same form i have compiled in forms10g and then when the when validate is fired it gives following error
frm-40933 Cannot populate table because datatype is incorrect.
CODE :-
PROCEDURE CHK_DISB_DT(RECNO NUMBER) IS
LOAN_DISB_TBL_TYPE ITEMS_IN_BLOCK;--DECLARE A VAIRIABLE OF TYPE ITEMS_IN_BLOCK
TYPE LOAN_DISB_REC IS RECORD(LNA_DISB_DATE DATE);
TYPE LOAN_DISB_TABLE IS TABLE OF LOAN_DISB_REC INDEX BY BINARY_INTEGER;
LOAN_DISB_TBL LOAN_DISB_TABLE;
I NUMBER;
DT DATE;
BEGIN
LOAN_DISB_TBL_TYPE(2):='LNA_DISB_DATE';
TABLE_FROM_BLOCK(LOAN_DISB_TBL,'PT_EMP_LOAN_ADV_DISB',1,ALL_RECORDS,LOAN_DISB_TBL_TYPE);
DT:=TRUNC(LOAN_DISB_TBL(RECNO).LNA_DISB_DATE);
END LOOP;

You've specified the lna_disb_date item to be the stored in the second field in the record but only 1 field has been defined for the record.
TryLOAN_DISB_TBL_TYPE(1):='LNA_DISB_DATE';Since you're only using the data from 1 record in the table you could make the code more efficient by using "recno, recno" instead of "1, all_records" and then reference the date as "dt := trunc(loan_disb_tbl(1).lna_disb_date)". Note that doing this might give a different error message to what you previously may have seen when recno is greater than the number of records in the block. So if recno could ever be too large then you should test to find the error which is generated.

How to configure TAF on RAC 10g

Hi,
I am facing issue with TAF over jdbc client. I have created the jdbc client (HelloWorld java program) to test TAF.
The following is my jdbc url:
"jdbc:oracle:thin:@(DESCRIPTION = (LOAD_BALANCE=on)(FAILOVER=on)(ADDRESS_LIST= (ADDRESS=(PROTOCOL=TCP)(HOST=10.77.242.35) (PORT=1521)) (ADDRESS=(PROTOCOL=TCP)(HOST=10.77.242.55)(PORT=1521))) (CONNECT_DATA=(SERVICE_NAME=dcnm)))"
Simply, i have created the connection through jdbc and put sleep in my code, meanwhile i down one of the db instance, then client code wake-up, but the connection is not failed over to another db instance. Please see below my tnsnames.ora file :

about jdbc thin + TAF
Oracle 10g JDBC/THIN Driver does not support TAF. TAF is only supported by the JDBC OCI driver.
http://download.oracle.com/docs/cd/B19306_01/java.102/b14355/ocitaf.htm#BABGIDEE
http://download.oracle.com/docs/cd/B28359_01/java.111/b31224/ocitaf.htm#BABGIDEE
Transparent Application Failover (TAF) is a feature of the Java Database Connectivity (JDBC) Oracle Call Interface (OCI) driver. It enables the application to automatically reconnect to a database, if the database instance to which the connection is made fails. In this case, the active transactions roll back.

How to use oracle servcies in roacle 10g rac

hi all,
I want to know how to use SERVICES in oracle 10g rac.I know how to create servcies i.e using srvctl create servcies or DBMS_SERVICES.
I know servcies can be used with JOBS using DBMS_SCHEDULER but i wat ot know besides jobs what are all the things we can used with services.

Yeah.That's right.
But in my case mwe are having a ERP applicaiton that has been build on oracle forms, so here we are having aeprate forms.Lets suppose that one form name is MEMBER.
and i have also created on servcie using
srvctl add service -d DB -s MEM -r RAC1,RAC2 -a RAC3
now my question how do i integrate this MEMBER form to services i.e MEM.
Like we can use in case oj create scheduling jobs using dbms_scheduler, we are having one prameter job_class where er have to specify the name of the parameter
but in my case how do i integrate it.
I hope you understandb my question.

RAC 10g - Undo full istance off

Hi,
I have Oracle Rac 10g environment with 2 istances in Solaris 10 SPARC.
For testing high availability, I have shutdown one istance and I have executed the performance test.
The undo datafile of instance off was filled, while the instance was running the other half, why?
Best Regards
Francesco Maisano

Hi Francesco,
Each instance in the RAC system can only use one undo tablespace at a time. In other words, instances cannot share undo tablespaces. Each instance in the cluster, being an independent transaction-processing environment, maintains its own UNDO area for undo management.
The undo tablespace cannot be shared among the instances at the same time. Only once an undo tablespace is released by an instance, it can be assigned to another instance. However, all instances can read blocks from any or all undo tablespaces for the purpose of constructing read-consistency images.
Switching Undo Tablespaces
You can switch from using one undo tablespace to another. Because the UNDO_TABLESPACE initialization parameter is a dynamic parameter, the ALTER SYSTEM SET statement can be used to assign a new undo tablespace.
If the parameter value for UNDO TABLESPACE is set to '' (two single quotes), then the current undo tablespace is switched out and the next available undo tablespace is switched in.
The database is online while the switch operation is performed, and user transactions can be executed while this command is being executed. When the switch operation completes successfully, all transactions started after the switch operation began are assigned to transaction tables in the new undo tablespace.
The switch operation does not wait for transactions in the old undo tablespace to commit. If there are any pending transactions in the old undo tablespace, the old undo tablespace enters into a PENDING OFFLINE mode (status). In this mode, existing transactions can continue to execute, but undo records for new user transactions cannot be stored in this undo tablespace.
An undo tablespace can exist in this PENDING OFFLINE mode, even after the switch operation completes successfully. A PENDING OFFLINE undo tablespace cannot be used by another instance, nor can it be dropped. Eventually, after all active transactions have committed, the undo tablespace automatically goes from the PENDING OFFLINE mode to the OFFLINE mode. From then on, the undo tablespace is available for other instances.
In another post I put the GV$ .. to you identify the cause of UNDO is full. (e.g Which transactions are on TBS UNDO full)

Error when adding a new node to RAC 10g

Hi all,
I have a RAC 10g environment test in Linux Red Hat Umbreakble 5 with two nodes. This RAC is fine on 2 nodes.
I want to add a new node (rac3) of the following way:
- The node 1 (rac1) is started and the instance ORCL1 is online.
- The node 2 (rac2) is offline. i.e the machine is off.
- The node 3 (rac3). The machine is on and already configured
So that when I execute the CRS_home\oui\bin\addnode.bat on node 1 and put the information of node 3 (Public node name, Private node name, Virtual host name) and press next I get the following message:
OUI-35000: Fatal cluster error encountered (PRKC-1071 Nodes rac2 did not respond to ping in 30 seconds) - Sure: The machine is off;
My question is: Can´t I add a new node on RAC if a node is off ?
Anybody can help me.
Thanks.
(Wander Brazil)

Interesting question.
You might have better luck getting an answer if you ask where people discuss RAC, instead of asking where people report documentation issues. (Go to http://forums.oracle.com and scroll down to 'Grid Computing' to see RAC forums.)
