Data Migration From WORD To ORACLE?
Sep 20, 2011I have a long file in WORD as I try to load it in ORACLE quotes become periods, ex:
insert into mytab values ('myname, 26);
when i copy this and paste it in oRACLE (UNIX environment), it translates as insert into mytab values (.myname.,26)..does not recognize the quotes.
I tried copying from word to notepad to ORACLE same problem..
Performance Tuning :: Oracle Data Migration
Jun 7, 2011We have a data migration scripts written for oracle. Data is not huge but we are observing that the migration is faster in the development labs but is 5x slower in the production site.
The development Oracle setup is on Windows and Production setup on Solaris. I have attached the AWR generated for a period where migration was run for 3 hours and stopped due to slow performance.
Here is my initial analysis.
1) The first timed events is the DB CPU. Hence I feel the migration scripts can be modified to run in parallel so that they can finish faster. However here the question arises why it should run faster in development env if this is an issue.
2) I tried increasing the
a.large_pool_size set to 512M
b.sga_max_size set to 8G
c.sga_target set to 8G
from 0, 4G and 4G respectively.
I have attached the AWR and below are the etc/system contents for solaris settings.
* Begin MDD root info (do not edit)
rootdev:/pseudo/md@0:0,1,blk
* End MDD root info (do not edit)
set noexec_user_stack=1
set noexec_user_stack_log=1
* IBMdpo vpath_START (do not remove)
* default SCSI timeout is 60 seconds
* uncomment to change SCSI timeout * set sd:sd_io_time=0x1e
forceload: drv/vpathdd
* IBMdpo vpath_END (do not remove)
set noexec_user_stack=1
set semsys:seminfo_semmni=100
set semsys:seminfo_semmns=1024
set semsys:seminfo_semmsl=256
set semsys:seminfo_semvmx=32767
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=10
P.S. The awr report is renamed to .txt from .html to be able to upload the file.

Data Migration From 9i To 11g R2
Mar 9, 2011We have our current production running on 9i and eventually want to migrate to 11g-r2. But the challenges are as follows:
9i production is running in San Francisco data center. 11g-r2 Production already setup up and running in Atlanta data center.
The database size is around 2 TB running on 9i. We are looking to transfer this to 11g-r2 and wondering, what options we have at our disposal: I was looking into EXP/IMP, but somebody said, dblinks will be much faster and reliable than EXP/IMP.
Data Migration With XML Files?
Aug 25, 2010we're planning a data migration from an application (oracle-based) to another (also with oracle db).
the origin is a ca. 80 GB database. so lots of millions of records are to be migrated. (before loading records into the destination tables, they have to be transformed).
the current concept is to receive all origin data in xml files, load them in a staging area (an own migration scheme in oracle), transform and load them into the destination tables.
we have three days for the whole migration (including extract from origin database, transform, load, backup after completion...).
my question is, that a migration with xml-files is a good concept. i think xml processing is much slower than doing the same with csv files. my proposal to migrate an oracle dump (so we got the original data in our staging area) was declined.
is migration mass-data with xml files good or are there performance or other issues?
SQL & PL/SQL :: Script For Data Migration
Mar 23, 2012I had a table with columns as below
employee_id
payroll_pay_week1

I have created a new table, so that instead of having 26 columns for payment amount for each week, I want to have one column for pay amount and one column to represent the week as below
employee_id
payroll_pay
payroll_pay_week
how do I migrate the data from old table to the new table?

Feb 19, 2013I have Arabic data stored into below two encodings in oracle AL32UTF8 database
1 Million rows into WE8MSWIN1252
.5 million rows into AR8MSWIN1256
in all cases I like to convert 1 Million row of WE8MSWIN1252 into AR8MSWIN1256. I could convert the data encoding from 1252 to 1256 using SQLdeveloper. But no luck using oracle export/import utility (both exp and expdp)…. I’m thinking may be certain locale is required for export/import to work.
Also my company said SQL developer is free utility may not be supported by oracle so use export and import for this, I need to convert only one table.

SQL Queries Taking Long Time After 11g Data Migration
Sep 14, 2010I have upgraded oracle database from 9i to 11g using export and import utility. After migration we are facing performance issue in report generation, We have observed that First execution of report is taking very long time and when we generate the same report 2 -3 times there is considerable change in the execution time and it is more better than the first execution.
2 days back I have restarted the database and found the same issue. There are around 300 Reports and it is not possible to generate all the reports 2-3 times every time we restart the database.

PL/SQL :: Legacy Data Migration Project - Cyclic Dependency Records
Mar 1, 2013It's been a while since I worked with SQL Plus . I am using Oracle 11g. We are working on a legacy data migration project. I have a table of records with circular dependency records. i am trying to identify the records. I have the foll. columns- Product,Source,target. I want o identify the records which form a loop. For e.g.
Source Target
A B
B C
C D
D A
Last record forms a loop-I need to identify these records. My query is below-
SELECT DISTINCT SOURCE,TARGET FROM RULESELIB WHERE CONNECT_BY_ISCYCLE=1 CONNECT BY NOCYCLE SOURCE=PRIOR TARGET;
I ran this query on 2 tables- one with 75000 records and the other with 25000 records. It works fine on the table with 75000 records completes within a minute but it does not complete on the other table. I can't seem to be able to figure out the issue with the query or is there something about the data that is causing this query to loop infinitely?
Migration From Oracle 10g To 11g?
Apr 26, 2011Our Application is on Oracle 10g and we are going to migrate to Oracle 11g.
1) As of now we are using ojdbc14.jar. So if we migrate can we use the same jar or is it mandatory with 11g to use either ojdbc5.jar or ojdbc6.jar. I guess these jar version depends on the version of jdk we are using. But we are using jdk1.5 and still we use ojdbc14.jar which is working fine. So is it like , Oracle 11g can support only jdk1.5 or jdk1.6 ?
2) Is there any effect on the coding part if we change ojdbc14.jar to ojdbc6.jar ?I have seen there are some extra classes used in ojdbc6.jar.
3) Also we are going to migrate the Oracle database from Solaris to AIX. Our application lies on Solaris.So is there any compatibility problem , if our application lies on Solaris and database on AIX ?
