Switch To Oracle DBA From Non Computer Science Background
Aug 16, 2010
I am on H1 visa and working as chemical engineer...but I am bored of this job... I wanted to switch to IT and particularly oracle dba..
How much is the risk for me as I am coming from non computer science background..there are various IT consulting companies who can provide training and do h1 transfer......currently (year 2010) the market for oracle is booming a lot...so I was thinking what can go wrong if I do this switch.

Im doing a project for my college and i need to transfer database. The thing is that i have created tables with databases and linked it to VB using ADODC.
I have done all this in the Computer at my home. So i have done all the project in my computer. I want to show the same project in my college, but i cant do it as the database is stored in my personal computer at home. Is there any ways i could transfer the database from my house to college like storing it in a pendrive. I used sqplus
oracle 9i to create the tables.

What are the differences of;
1. ALTER SYSTEM SWITCH LOGFILE;
2. ALTER SYSTEM ARCHIVE LOG ALL;
3. ALTER SYSTEM ARCHIVE LOG CURRENT;
I read Oracle's document but still didn't understand the difference in real life-use.
If you were writing a hotbackup script, which would you use at the end of datafile copy?

I recently started working with legacy code and noticed that some huge tables (5 years worth of data, don't have more details on me right now but can post later if needed) are partitioned based on time sequence number column while majority of queries are done based on time (different column). Queries performance is degrading and I'd like to try to modify partitioning and run some tests to evaluate performance improvement.
My only concern is with so much live data I have to come up with solution on how to switch partitioning with the least impact on applications running 24 x 7. Something you have done in the same situation and it worked?

I have an Oracle database 11.1.0.6 with ASM storage.
SQL> select * from v$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
PL/SQL Release 11.1.0.6.0 - Production
CORE 11.1.0.6.0 Production
TNS for Solaris: Version 11.1.0.6.0 - Production
NLSRTL Version 11.1.0.6.0 - Production
There is a disk group named +FRA which has only 1 disk (call it disk 0 for later references).
+FRA disk group is in type of EXTERNAL redundancy
I'd like to add another disk to +FRA disk group and copy all files stored in disk 0 to the new disk (call it disk 1 for ex.), then take off disk 0 (not use for +FRA disk group any more).
Expected result: there is only one disk 1 left in the +FRA disk group, with all the data from disk 0 and keep their original file names

I have seen in many RMAN backup scripts that a manual log switching is performed in first line of the script? What is it purpose, just to write changes needed to reconstruct the DML/DDL statements to online redo logfiles and start the archiving process if db is running in archive log mode?

I am trying to connect to a database located at my work from at home. I am running into the following issue (see command and error below):
ansichart@ansivm:~/src/perl$ sqlplus aspxdba/********@aspxp2 SQL*Plus: Release 11.2.0.3.0 Production on Thu Jul 18 21:15:09 2013 Copyright (c) 1982, 2011, Oracle.
All rights reserved. ERROR:ORA-12545: Connect failed because target host or object does not exist-- Here is my tnsnames.ora file (I have the service_name censored out for privacy reasons):-
ansichart@ansivm:~/src/perl$ cat $ORACLE_HOME/network/admin/tnsnames.oraaspxp2 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = orarac9-scan)(PORT = 1521)) ) (CONNECT_DATA =(SERVICE_NAME = *****************)(UR=A) ) )-
I have verified that I can establish a TCP connection to this DB server on the port specified, using the same info from the TNSnames.ora file (see below):-
---ansichart@ansivm:~/src/perl$ nmap -sT -p 1521 orarac9-scan Starting Nmap 5.21 (URL.... ) at 2013-07-18 20:53 CDTNmap scan report for orarac9-scan (10.1.13.115)Host is up (0.0088s latency).PORT STATE SERVICE1521/tcp open oracle Nmap done: 1 IP address (1 host up) scanned in 0.09 secondsansichart@ansivm:~/src/perl$--
I have another terminal opened up to a server at work and I can connect to the DB with sqlplus just fine. I verified that the record for this database on the tnsnames.ora file is the same as it is at work. In conclusion, I can connect to the Database at work, but I cannot at home, even though I am using the same connection information and verified that port 1521 is accessible on this Database server from at home. So why can't I establish a DB connection?

I configure exadata + 2 switch between application server and and exadata. And we have problem to connect to switch and load balancing between Ethernet switch to exadata.
We might end up that is 'How about remove ethernet switch and directly connect to exadata?' I don't know which idea comes up with Ethernet gigabit switch between application server and exadata, exadata might be gigabit.
but from application server to ethernet switch is still 100M network, it is only fast in that load, other load is still 100m , it might useless. and about load balancing, exadata is RAC cluster node, exadata is doing load balancing, why we want another load balancing feature of ethernet switch?
Is it good idea to have dual switch between application server and exadata? exadata iti is what might be pro and con of this setting? exadata is handled by oracle support team, but dual switch is only cared by application operation team, so if something wrong with switch, nobody except operation team can manage .

Just wanted to know if I do
ALTER SYSTEM ARCHIVE LOG CURRENT;
Then it archives the current redo and switches to next redo.
If again switching is done, then just wanted to know if redo is archived when its size is less than log_buffer, then is it resumed when it is switched into next time or after archiving it creates a empty redo file and then use it?

I have got a form in tabular format. each record contains some specific colour or it may not contain.
i want to chage the backgroud colour of that record based on what so ever user wants. for example, user want first record should be of RED back groud, second green, third blue etc.
colours are available in RGB format.
when i try to set_item_property(backgroundcolor) on post-query or on when new item instance, it makes all record of same colour.
note:- if a put another text/display item and make it number of record displayed property = 1 , then it works, because only one record colour is seen at a time.
I can not use multiple visual attributes because number of colours are up to user feedback.
how can it be applied in tabular format?
