SQL & PL/SQL :: Read DIST From DISTANCE Where Origin And Destination Is From Cursor
May 30, 2013
CREATE OR REPLACE FUNCTION TRIPLENGTH(tripnum TRIP.T#%TYPE)
RETURN NUMBER IS
TNUM TRIPLEG.T#%TYPE;
LEGNUM TRIPLEG.LEG#%TYPE;
ORI TRIPLEG.ORIGIN%TYPE;
DES TRIPLEG.DESTINATION%TYPE;
[code]....
i am trying to read values from TRIPLEG to a cursor (it will return 6 rows). from the cursor, i am trying to read DIST from DISTANCE where the origin and destination is from the cursor(6 origin and destination so should return 6 dist) the dist should be added up and store in TDIS. then it return TDIS.
ORA-01403: no data found
ORA-06512: at "user.TRIPLENGTH", line 1
ORA-06512: at line 1
I have one Latitude and Longitude points. I need to calculate distance between them.Right now we are using HAVERSINE formula but the query takes longer time to complete.
I have a repeating frame wich displays each item and its quantity and pricethe second frame is a fixed frame which will display the total and price after discount.both frames are enclosed in the same frame.I made space beteewn the two frames so the second frame always prints in the same placewhen I run the report the second frame appears in the second page and the first frame (items in invoice) appear in the first page.
I've tried to change the vertical and horizental properties of the frames but the report is still the same
My DB is in Max Protection mode. In case Standby archive destination gets full & oracle cannot archive standby redo log to standby archive destination, will the primary database shutdown?
I am unable to find out the location of my archive logs. The VALUE field is null.

I m using Oracle Forms 6i and Oracle 10g Express Edition. I am having the following error message when I am trying to connect to the database from client.I have dont following configuration in my client's FORM's TNSNAMES.ORA file.
I am having trouble connecting to oracle forms 4.5, I keep getting an "Ora-12203:TNS:unable to connect to destination" eror message. I am able to connect using sql plus or other similar application so there is no problem with my tnsnames.ora file.
by default backup area is FRA, It can be change by db_recovery_file_dest FRA contains archivelog ,backupset,datafile,onlinelog folders..
NOW, i specially want to change backup dest. of archvelog to C: (suppose i have C , D, E, F , G) - (i know for archivelogs its log_archive_dest_N command can backup copies to other location but it also goes to default FRA )
backupset to D: datafile to E: onlinelog to F: controlfile to G: ALL SHOULD CONTAIN ONLY 1 DESTINATION NOT 2 FOR BACKUPS
I installed Oracle 11g Express edition in my local Machine(Windows 7).listener.ora, tnsnames.ora files seems fine. Service and listener are running; While trying to connect to the my db sqlplus>connect sys/oracle as sysdba
I am getting "ora - 12543 TNS: destination host unreachable."
what could be the issue. Find below listener.ora, sqlnet.ora, tnsnames.ora files:=
I install oracle database 11g and developer 6i on windows7 64bit server everything is working fine on the server and i install developer 6i on windows XP on client now i'm getting "ora-12203:TNS: unable to connect to destination" when trying to connect the server. i have check the TNSNAMES.ORA file the configuration is fine. then why i'm getting this message?
this my f drive space is full so i want to change this my archive destination to my another g drive so how can i do this.and if i change this my archive destination does its affect any problem while recover my database in future.
We have a request to configure data guard for databases on the production server. Here is my situation:
We have a backup strategy in place where the backups are being taken on a regular basis. Archive logs are deleted as soon as they are backed up.
My question now is , is there a way of configuring the Data guard in such a way that there would be no change to existing backup strategy (RMAN) and still duplicate the archive logs to another destination and not delete the archive logs by RMAN backup process on that destination while the first destination is deleted.
We will be deleting the logs in the second archive destination using a script which checks if the logs were applied.
RMAN-03009: failure of backup command on t1 channel at 12/15/2012 06:15:11 RMAN-10015: error compiling PL/SQL program RMAN-10033: error during compilation of job step 2: ORA-00603: ORACLE server session terminated by fatal error ORA-04030: out of process memory when trying to allocate 400 bytes (PL/SQL DIANA,LISIMA: Add cells)
We received the above error message after the following event:
rman failed to backup because archivelog destination was out of space
We moved SOME of the archivelog file manually using operating system command mv to another location so that our application can run first.When the engineers restarted the rman to backup, we receive the above error.
I'm dealing with an ORA-1000 error in a Pro*C application where all the cursors are correctly closed (or so it seems to me).
Here is the code for a simple program which reproduces the problem:
Each cursor is opened in a PL/SQL package:
CREATE OR REPLACE PACKAGE emp_demo_pkg AS TYPE emp_cur_type IS REF CURSOR; PROCEDURE open_cur(curs IN OUT emp_cur_type, dept_num IN NUMBER); END emp_demo_pkg;
[Code]....
While testing the initialization parameter open_cursors is set to 50.
It's my understanding that Oracle doesn't close the cursors until it needs the space for another cursor, which in my test case seems to happen when I enter a value of 50 or bigger for "number of loops". To see how oracle is reusing the cursors, while the test program is running I run SQL*Plus and query v$sesstat for the session that's running the test with the following sentence:
select name, value from v$sesstat s, v$statname n where s.statistic# = n.statistic# and sid = 7 and name like '%cursor%';
Even before I enter a value for number of loops I can see that the session opened 4 cursors and closed 2 of them:
NAME VALUE ---------------------------------------------------------------- ---------- opened cursors cumulative 4 opened cursors current 2
Entering a value of 5 for number of loops yields
NAME VALUE ---------------------------------------------------------------- ---------- opened cursors cumulative 11 <----- 7+ opened cursors current 8 <----- 6+
With a value of 30
NAME VALUE ---------------------------------------------------------------- ---------- opened cursors cumulative 36 <----- 25+ (apparently, Oracle reused at least 5 cursors) opened cursors current 33 <----- 25+
With a value of 47
NAME VALUE ---------------------------------------------------------------- ---------- opened cursors cumulative 53 <----- 17+ opened cursors current 50 <----- 17+
Now I reached the upper limit set by the initialization parameter open_cursors.
Entering a value of 48, I get the ORA-1000 error.
ORA-01000: maximum open cursors exceeded ORA-06512: at "SCOTT.EMP_DEMO
Since I open and close the cursor in the same loop iteration, I expect to find in every iterarion 1 explicit cursor and a number of implicit cursors (the PL/SQL call along with the so-called recursive cursors), but I don't expect the sum of all of them to be greater than 50. If my understanding is correct Oracle should be reusing the 50 cursors previously marked as "closeable", not raising the ORA-1000 error.
I want to replicate single table data/modification from source db to destination DB.procedure or steps how to create replication between source and dest db for single table.
Our application is using a two instance, one for the live active data and the other for the reports data. We have a process which moves the data from the live instance to reports instance every night. In a single db environment the process is working without any issues. However when we move to the RAC environment the reports db's (insert) in large table get locked and we are unable to insert data to the reports db.
What we are performing is:
Insert into my_table_rpt select * from may_table_live@db_link_to_livedb;
Issues:
my_table_rpt get locked
We have found the workaround by disable locking in destination and subsequent to the insert enable locking
ALTER TABLE my_table_rpt DISABLE TABLE LOCK;
Insert the data to the reports database table
Then
ALTER TABLE my_table_rpt ENABLE TABLE LOCK
Question:
Why does the large destination table (my_table_rpt) get locked in the RAC environment?
i am using client-server environment without using a domain.On One computer i have installed Oracle 8.0.5 and developer 2000. and on client side i have installed form 6i. i have made a service (star) in Tnsnames.ora in client side.
I have a situation where I want to configure primary database (11.2) with 2 remote destinations. dest_2 is the default and points to a standby on host_2. However, I also want the primary db to continue transporting redo to dest_3 on node_3 when node_2 is taken down (planned or unplanned).
1) Configure the ALTERNATE attribute of dest_2 to point to dest_3.
2) Configure tnsnames client-side failover on primary host to point to 2 nodes (node_2 and node_3).
-define a cursor with bind variables -get a cursor record from these cursor -and pass the bind variable in the OPEN clause
Did'nt succeed as shown in the example.

when I am trying to send report for prints then I received this error.
