I am using UTL_TCP package of Oracle to connect to remote server. As per my architecture, I am opening multiple connections TCP in the same Oracle session.
I have come arround the limiation of 16 connections with this package.
code for using utl_tcp for communication between client and server.
my requirement is: i am using utl_tcp package for tcp/ip communication between client(my client application based on c#) and server(plsql code for server).
when i am sending data to client, then client receives that data successfully but when client sends back some data to server, my code does not receive client's requested data.
Using UTL_TCP package (for the first time; maybe there's smarter way to do that), I captured contents of a certain web page. The page contains (along with some text, images, etc.), a list of values I'd like to extract. Something like this:
PRVI miravira pond 23.7.2010 102,2221
NEKI miravira pond 23.7.2010 105,0996
DRUGI miravira pond 22.7.2010 101,3789
The result (output) of the PL/SQL procedure contains several hundreds of lines. I narrowed the output to a part which I'm interested in. It looks like this (a screenshot, because [code] or [pre] tags won't allow me to paint text, while the others don't preserve formatting):
Red values are what I'm looking for. The first one represents a date (July 23rd 2010), and the second one is amount (105,0996).
Now, what's the problem: the above mess doesn't look the same every day (probably because the rest of data that appears on a web page changes too). Therefore, SUBSTR (with hard-coded positions) that seems to be working today is wrong tomorrow. Moreover, IF condition I used might not provide desired part of a web page every time.
Here's the code (modified a little bit, unimportant for what matters):
declare
c utl_tcp.connection;
n number;
buffer varchar2(255);
l_x_dat varchar2(10);
l_x_izn varchar2(10);
[code].....
L_X_DAT and L_X_IZN are values I need. SUBSTR parameters, as I said, are far from being good.Is there any smart way to extract those two values? What (Oracle) technology could be used here? Or should I just try to, somehow, set SUBSTR values correctly (dynamically)?
If there was a way to uniquely fetch those values (instead of getting the whole web page and digging for what I'm interested in), it would be extraordinary.
I am trying to use utl_tcp to connect, through TCP/IP, to a 3rd party program PC Miler. When I use telnet, PC Miler works without any issue. However, when I use utl_tcp, beginning from the second PC Miler API call, when I do a utl_tcp.get_line to get the result, the first line that return is always blank (with 1 white space). Here is my program.
---------------------------------------------------
DECLARE
c utl_tcp.connection;
ret_val PLS_INTEGER;
v_data VARCHAR2(4000);
BEGIN
c := utl_tcp.open_connection('mars', 8145);
[code]....
Note that the 1st and 3rd API call is the same and should give me the same results. The 2nd API is supposed to give me 1 line back. At the end of each output, the server will end will the word "Ready". I use that to indicate when to exit the loop.
If I disconnect and reconnect after each API call, each output result will be correct because each API call will become the "1st" call since connection - like this program:
DECLARE
c utl_tcp.connection;
ret_val PLS_INTEGER;
v_data VARCHAR2(4000);
BEGIN
c := utl_tcp.open_connection('mars', 8145);
[code]....
If there is something wrong with PC Miler, why would it work when I telnet through a Windows Command prompt? If it is not PC Miler and utl_tcp, what else can be wrong?
I've written a .net program for inserting blobs into our database, and it works fine, except if the path has more than 30(+) characters. I've read that this is a limitation in oracle, but the actual contents being stored is just the filename, extension, and blob itself, so I'm not actually storing anything more than 30 characters.

For the another profile LIMIT value is mentioned as UNLIMITED.
Working on building an application which will be in C# (.NET 3.5) and some PL/SQL. However, for the tables which have to store the data, I added a column, comments, to the table and assigned it a data type CLOB. No big deal, except my PL/SQL function is giving me errors if the CLOB built from several varchar2 rows exceeds 4000 characters. I understand the varchar2 field is restricted in 10g, but I was under the impression there wasn't such a restriction on a CLOB (hence the reason we're using it.)
I end up getting:
ORA-6502: PL/SQL: numeric or value error: character string buffer too small

I'm using Toad 11.6, I can see about 156 sessions for the database in the session browser but when I do a select from v$session, only 40 sessions are showing up. I was able to look at all the sessions until yesterday. I tried several views like v$session, v$open_cursor etc, but only 60 sessions show up. I'm connected to the database using same user login yesterday and this morning.. May be this user had some privileges revoked last night??If so is it possible to limit sessions in these views (v$session etc) but it's strange that I can see them in the session browser in Toad. 'm very confident that there are 156 sessions in the database but it's just that I'm not able to see them in the v$session etc views. I need to troubleshoot a session but it is not showing up in any views.
View 9 Replies View RelatedI have a problem with one table.. First of all:
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
The problem table resides in a locally managed tablespace. About 10 millions records is added in this table every day. After 36 hours all these records moved to another (partitioned) table, so the size of data in the problem table always about 75 Gb. But the size of table is reached 157 Gb today, and it still growing. The results of dbms_space.space_usage are showed below:
Size of blocks with:
0-25% free space: 4726784
25-50% free space: 17301504
50-75% free space: 24920064
75-100% free space: 102418669568
full blocks: 54761594880Thus, a lot of blocks have 75-100% free space but the table constantly growing: during last 9 days the size increased from 123 to 157 Gb.
how to stop the table growing? It there any way to limit the table size in locally managed tablespace?
I'm looking for the information on:
•Limit of number of sub programs in a package.
•Limit of number of lines in a sub-program.
•Limit of number of statements in a sub-program.
I searched on net and found below useful information.
The size limit for PL/SQL stored database objects such as subprograms, triggers, and packages is the size of the Descriptive Intermediate Attributed Notation for Ada (DIANA) code in the shared pool in bytes. The Linux and UNIX limit on the size of the flattened DIANA/code size is 64K but the limit might be 32K on desktop platforms.
The most closely related number that a user can access is the PARSED_SIZE in the static data dictionary view *_OBJECT_SIZE. That gives the size of the DIANA in bytes as stored in the SYS.IDL_xxx$ tables. This is not the size in the shared pool. The size of the DIANA part of PL/SQL code (used during compilation) is significantly larger in the shared pool than it is in the system table.
is there any recommendation on limit of number of subprograms should exist in a package exist, If there is any guidelines/recommendation exist for these.
The following link states
Quote:
SESSIONS_PER_USER
Each instance maintains its own SESSIONS_PER_USER count. If SESSIONS_PER_USER is set to 1 for a user, the user can log on to the database more than once as long as each connection is from a different instance.

Of course the following is not working even when resource_limit is TRUE
ALTER PROFILE DEFAULT LIMIT SESSIONS_PER_USER 2;
How can I restrict a user to have limited sessions say 2 sessions across 4 node cluster? Presently I am checking the sessions logged in using sql+ and no connection pooling of front end etc. is involved.
In regard to the Oracle 4GB limit, what exactly is this limit? Is this the total size of the datafiles of the user defined tablespaces (excluding SYSTEM and UNDO) so if, for example, we have a 2.8Gb datafile, can we only add another 1.2Gb datafile.
or is it the total size of extents/segments in the user defined tablespace i.e. if we have a 2.8Gb datafile but the database data comes to only 1.7Gb, can we add another tablespace with a new 2.8Gb datafile to allow for another 1.7Gb schema.
I have a question regarding a selection limit from a list of values. The table where my IDs (unit_codes) come from has another column called 'points'. each ID has its own number of points. Is there a way to put a selection limit on the display field that points will be placed on?
FOR EXAMPLE: a course block has a selection limit of 70 points, A person named someguy selects :
music = 20 points
maths = 20 points
mathsXTRA = 40 points
**ALERT!!! - U can ONLY select 70 points worth of units**

The procedure uses bulk collect to fetch from a normal cursor, Then I am using for all to insert into target table, The number of rows are 234965470
Question: What should ideally be the limit for my bulk collect ?
According to below, it should be in hundreds[URL]...
I put a bulk collect limit of 50000 - took close to 2 hours then i tried 10000 - just 3 mins shorter than the above time But if you commit every 500 rows, Then is there not another theory that frequent commits is not good ?
Is there something I have to ask the DBAS ?

View 6 Replies View RelatedI have to optimize a batch job which returns > 1 lakh records . I have a commit limit being passed . I am planning to divide the cursor records for processing as follows.

After this is done, i will fetch the next 200 records from the cursor and repeat the processing. I would like to know how i can divide the cursor records, and fetch "limit" number of records at a time and also be able to go to the next 200 recs of the cursor next time.
