SQL & PL/SQL :: Creating A Database From Scratch
Apr 10, 2011
I just started using SQL PL/SQL a couple of weeks ago and am now creating a database from scratch.The tables have all been created, and I'm now doing the triggers. One in particular is giving me a headache...
I have 3 different types of client, A, B and C. Each class gets a discount bigger than the one before, and you need to buy until you reach a threshold of X before you move to the next class. I'm trying to do the following trigger:
When I update one of the threshold for the class, I want to make sure the new value isnt bigger than the value of the next class. For example, if a client needs to buy for 100$ before moving to Class B from A and 200$ to move from Class B to Class C and I update the first threshold from 100$ to 250$, I want an error message to pop up saying the threshold is too high.
Right now the Class table looks like this:
Class ID (A,B and C)
Threshold (0,100 and 200)
Discount (0, 0.05, 0.10)

DB = Oracle 10.2.0.4
OS = Solaris 10 Sparc
I am trying to create a physical standby database using the add standby database option within OEM 10g. This is something we have done numerous times before on 10g and 11g db's without a single issue, but for some reason, this time after selecting my RMAN backup location and staging area location , I am getting the following error when I click Next:
RMAN Backup Location - The specified RMAN backup is invalid. Could not identify controlfile from the backup
It is the latest backup (using RMAN catalog) from the previous evening and includes datafiles and control file.
Here is the output for List backup:
BS Key Size Device Type Elapsed Time Completion Time
------- ---------- ----------- ------------ ---------------
1741586 7.70G DISK 00:03:26 06-DEC-12
BP Key: 1741590 Status: AVAILABLE Compressed: NO Tag: TAG20121206T220033
Piece Name: /carebackup/oradata/CARELIVE/carelive/backup/df_CARELIVE_4811_1.bus
[code].....
The only difference between creating a standby for this db and others we have created is that the file system the backups are stored on is on a non-global zone shared via nfs mount.
I know that when I try and share that filesystem with other servers I get the message: share_nfs: Cannot share filesystems in non-global zones If the /backup filesystem is not shared with any other servers would OEM be able to read from that NGZ? The filesystem is available to connect to using ssh from other locations, but not sure how OEM handles this part of the process.

We have a 2 database identical ( Say DB1 & DB2). In that, one of the database(DB2) base got corrupted. We cant recover back the database due to hard disk problem. So we did a new installation of database and patched to current level.
Now I want make DB2 up and running. So I though of generating a script from DB1 and run it in DB2 to restore back.

Just installed the new 2.0.8 version. Its been a while I am interested on using PM for our company.The problem I have is creating an Oracle DB connection. When I create a new Oracle DB connection, and test it, Steps 3 and 4 fail.What is strange is that I followed the following procedure in PM 1.9-825 and worked fine. I am wondering if something changed in the new PM 2.0.8 version (I noticed that php_oci8.dll was commented out in php.ini).
Oracle Version is 10GR2
PM installed on clean XP sp3
1. Got a new Windows XP SP3 PC
2. Installed PM 2.0.8
3. Edited php.ini and uncommented [PHP_OCI8] and extension=php_oci8.dll
4. Installed oracle instant client “instantclient-basic-win32-10.2.0.5” in c:oracle
5. Installed oracle instant client “instantclient-sqlplus-win32-10.2.0.4” in c:oracle
6. Added c:oracle in PATH environment variable
7. Created ORACLE_HOME = c:oracle environment variable
8. Added TNS_ADMIN = c: environment variable
9. Copied working tnsnames.ora file into c:
10. Rebooted.
-------------------------------------
1. Tried sqlplus connection to my oracle db and worked.
2. Launched PM
3. Created a new process
4. Created a new DB connection as follows:
a. Engine:Oracle
b. Server:192.168.xxx.xxx
c. Database name: my_name (where my_name appears in tns_names.ora)
d. Username:my_username
e. Password:my_password

Sun Solaris 10, Oracle 11gr2 x86 How are you doing? I am trying to build a test system. I never build ASM before. if I need to install database first then Migrating to ASM? The other problem I am having is that I only have a Raw disk. I have one disk for root and oracle and the other one for Raw disk for ASM. Do you know it's possible to build ASM on 1 raw disk?

based on a provided list of key values, joining the collected list against a source table to retrieve additional information related to the key. In this simple example, the procedure accepts a list of employee numbers. The goal is to print a list of names associated with those numbers.
The method is to materialize the list of employee numbers as rows and join those rows to a source table to get the names. I have used BULK COLLECT. Why we cannot cast PLSQL tables using a type defined in the procedure's specification (why the type needs to exist as an object before we can cast it, like this:
SELECT * FROM TABLE ( CAST ( SOME_FUNCTION(&some parameter) AS SOME_TYPE ) );
here is my demo SQL, which you should be able to execute against the SCOTT schema without any change
declare
type employee_numbers is table of emp.empno%type index by binary_integer;
type employee_names is table of emp.ename%type index by binary_integer;
type employees_record is record (empno employee_numbers, person_name employee_names);
records employees_record;

I am getting a ORA-03114 (not connected to Oracle) error when I am creating a DB using DBCA. Here are the steps that I do:
1) Log onto the server remotely, using Exceed Query
2) Connect as the oracle user (Oracle)
3) set ORACLE_HOME, PATH
4) Run DBCA, give parameters
At around 12% and again at 19%, I get the error (see screenshot). I also tried to generate the scripts and run them remotely, and the steps run successfully upto & including the step " startup nomount pfile="/oracle/admin/<dbname>/scripts/init.ora"; ". After that, when I try to run the script specified in rmanRestoreDatafiles.sql from SQL> prompt, the error appears, and connection to ORACLE is lost.
Googling the error shows that it is a connectivilty issue, and Oracle says that it is usually caused by user scripts. But I am not running any user-created scripts as part of the DBCA process. Somehow, the instance is timing out immediately after doing the "startup nomount".

This is on a vmware virtual server on Windows 2008R2 using ORACLE 11g R2 with patch set 6
I installed ORACLE (software only) and applied patch set 6 and tried to create a new database.
during the database creation I got an error as the system was adding the JVM that read:-
ORA-01927:cannot REVOKE privileges you did not grant.
I was given the options to ignore or abort
I chose to ignore the error and continue.
After the database creation completed I looked in the jserver log copied below and found two errors
I did not get the same error before installing patch set 6
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
No errors.
alter system flush shared_pool
drop role javauserpriv

I need to create a trigger for the below case:
index_id Time_vertex_id date rate pre_rate
4 1 17-06-2011 4.7 6.4
4 1 16-06-2011 6.4 7.4
4 1 14-06-2011 7.4
4 1 15-06-2011 8.4 7.4
the index_id and time_vertex_id will be unique and when the date is 17th i.e the first date will be inserted the current rate will be 4.7 and the previous rate will be blank and when another date is inserted i.e 16th the previous rate of 17th will be the current rate of 16th i.e 6.4.
when 14th is being inserted, the previous rate of 16th will be the current rate of 14th i.e 7.4 and if after 14th is being inserted, 15th is being inserted, then the previous rate of 16th should be updated as per the current rate of 15 say 8.5.
