I have written a Database procedure to move data from one data to another database using Database link. When i run that procedure on Sql it is running fine, but i use same procedure in a button in form using "When-Button-Pressed" trigger it generates error, error code is ORA-02055 and ORA-02067.

The requirement details are as below,
1) The database contains static as well as transactional data for telecom domain.
2) We have to move region-wise data from one database to another.
3) There are around 10 regions.
4) The region wise data extraction from source db is based on around 40 to 50 tables. Rest of the tables contains static data & it will not change.
5) The volume is around 1 million subscribers per region.
6) The migration is required because
a) The client is upgrading its base product which uses this database
b) There is a change in structure of static tables
c) Hardware upgrade
d) The client want to start with single region on new database & rest of the regions will be operated from old database.
7) Keep execution time to very minimum.
I am thinking to have solution as below,
1) Create destination database with upgraded db structure (as mentioned in 6b)
2) Create database links to access source db in destination db.
3) Write SQL queries to fetch data from all the respective tables for a specific region
4) Write separate PL/SQL blocks for each table to fetch data from source db & insert into respective table in destination db
a) Use FOR ALL & bulk collect to improve the performance
b) Divide table data into multiple chunks & execute parallel batches (around 10) to insert the data
5) Validate pre & post counts to verify the success of migration
I have one PLSQL package that does a join of two tables of remote database instance via the datalink. I just wonder where the most calculation(the join) is done, local machine or remote machine? Is there any best practice to have a better performance for such configuration.

Error: ORA-16535: CRS is preventing execution of a broker operation
Oracle Says
Quote:Cause
A broker operation was underway that required CRS to stop managing the instances of this database, but CRS management could not be stopped on behalf of the broker"s request on at least some of the instances, so the broker operation was canceled.Suspend CRS management of this database using SRVCTL STOP DATABASE -D <name> -O NONE. Then reissue the broker request.But this command is not working as it's given to stop the database.
One more thing, it's nowhere said to stop CRS while performing Switchover / Switchback using DG Broker. When we do Switchover / Switchback we keep open only one of the Primary instance.
is there any documentation / link available to switchover of RAC database using dgmgrl (DG Broker)
We have this archicture:
OLPT DB --> OLPT DB (Physical Standby, active dataguard) --> Data warehouse DB
We only allowed to connect to OLPT DB (Physical Standby, active dataguard) from Data warehouse DB. If there is possibility to use some of Oracle "native" method of data extraction (replication) from OLPT DB (Physical Standby, active dataguard) to Data warehouse DB.
As far as I know we cannot create materialized view log in OLPT DB (Physical Standby, active dataguard) in order to do data replication, but maybe there is some others ways?

View 3 Replies View RelatedI got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site
If flashback is enable in physical standby database 1.

Here we have a data guard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. Also we configured one schema on a third machine as catalog database using following steps. The steps executed in catalog database(appsdb):
SQL> create tablespace rmancatlog_tbs datafile '/u01/app/oracle/oradata/NEW/rman_catalog.dbf' size 500M autoextend off extent management local segment space management auto;
SQL> create user rman identified by oracle
2 default tablespace rmancatlog_tbs
3 quota unlimited on rmancatlog_tbs
4 ;SQL> GRANT connect, resource, recovery_catalog_owner TO rman;
RMAN> create catalog;
recovery catalog created
Added tns entries of catalog database in primary and standby. Then from primary database we tried to register to catalog database. It is showing that it is registering. But every query afterwards in rman is throwing the error. Below are the steps and error:

We are migrating a proc application as described below.
Old Env: UNIX
Old DB: Oracle 8i
New Env: Linux
New DB: Oracle 11g
New modules are successfully compiled in Linux environment. But we are facing issues in writing the output of VARCHAR datatype to a file.
find below the extract of code.
EXEC SQL BEGIN DECLARE SECTION;
varchar mcolmnvarchar[4];
EXEC SQL END DECLARE SECTION;
EXEC SQL DECLARE crs CURSOR FOR
SELECT NVL(colmn,' ') FROM table1
memset(mcolmnvarchar.arr,'�',4); //Was added for only Linux migration. Not present in unix env.
EXEC SQL FETCH c1 INTO :mcolmnvarchar;
cout << "Data at Stage one"<< mcolmnvarchar << endl;
mcolmnvarchar.arr[mcolmnvarchar.len]='�';
cout << "Data at Stage two"<< mcolmnvarchar << endl;
fprintf(fptr,"%-4s",mcolmnvarchar.arr);
Above code works absolutely fine in Unix env with Oracle 8i. But with Linux env & Oracle 11g it is not working. No compilation or run time errors. Data at Stage one prints the output of database properly. But after null terminator code, Data at Stage two statement prints without any value. Value is lost after null terminator code.

I need to migrate data from Mysql database to Oracle11g database.
a) is there any method available to import the all the sqls like table script,constraint scripts,data(insert ) script from Mysql.so that we can apply the sql directly to the oracle schema after making necessary changes(like datatype).
b) Is there any free tool available for the migration.
We plan to move the database to a new host with much more RAM, CPU. The new database server will have exactly the same OS version, Kernel version and the same version of database / grid standalone (ASM). I will have to install OS, Database software, Grid Standalone on the new server.
The current version of the database is 11.2.0.3.0 Enterprise Edition and the OS version is Oracle Enterprise Linux 6.3. However, we plan to use the same disks (ASM disks). I believe I don't need to use RMAN to do the migration, Is it correct?
I have to move data from old tables into new tables. I use a sqlplus script and execute multiple 'insert from select'. I thought the SQL statements are executed in sequence, one after the other. I run into this problem: Let's take this script for an example
insert into A (a,b,c,....
select a,b,c......
from X;
insert into B (a,b,....
select a,b,....
from A joined with Y;
commit;
After executing the script in our development DB
select count (*) from A
returns 200
When the script is executed in production, A table record count is 5
select count (*) from A joined with Y; (used in the second insert)
returns 200.
It seems that the two statements are executed at the same time and table A is not fully populated when the select in statement two is executed.I suspect this is due to parallel execution in production.
Will executing
ALTER SESSION DISABLE PARALLEL DML;
ALTER SESSION DISABLE PARALLEL QUERY ;

View 4 Replies View RelatedI have database A and B , we are strictly restricted to not to create any DB links between these database.

Question here :
1.When we try to bulk collect all the data into table type , i am getting error operand exceeds limit, but it is mandate to put all data in one short to table type as dot net will take that and insert into B database.
