SQL & PL/SQL :: Terminate Script If Remote Database Is Down?
Sep 19, 2011I have a simple script which fetch data from another SQL server database.
The remote SQL Server database is accessed by oracle thru gateway, and a simple DB link is made in local database to the remote oracle datbase (which actually access the MS SQL Server)
The SQL script empties all the data in local database, and fills it with the fresh data from MS SQL server.
Problem is sometimes SQL Server is down, and i lose all the data in local database. The script runs automatically as schedualed job. I want to make my script intelligent enough to terminate the script if the other database is down.
Server Utilities :: Slow Exports Using Exp Command Due To Open Sessions
Nov 11, 2011I have had the following problem open with Oracle support since March 2011 (8 months), and still no resolution.
When I export all our schema's on Sunday night it takes about 1 hour 50 minutes. When I export the same schema's on any other night it takes 7 hours. The only difference is that on Sunday at 4:00am we drop all connections in the connection pools and reestablish new connections. Then 19hours later on Sunday at 23:00 we perform the exports which only take 2 hours to complete.
I have also tried recreating the connections in the connection pools during the week, and the exports have then only taken 2 hours to complete. But the following night after the connections have been used during the day, the exports again take 7 hours. So it appears the export speed gets significantly slower when there are many open connections that have been used and not closed.
From the stats pack report I found 2 SQL statements internal to the export command, that had an order of magnitude in difference when looking at the elapsed execution time between the fast export, and the slow export (see below).
How to speed up the exports without having to drop and recreate the database connections in the connection pools each night.
FAST:
elapsed_time: 430.90
executions: 161,388
Module: exp@Oracle1 (TNS V1-V3)
SELECT COLNAME, COLNO, PROPERTY, NOLOG FROM SYS.EXU10CCL
WHERE CNO = :1 ORDER BY COLNO
elapsed_time: 264.29
executions: 50,349
Module: exp@Oracle1 (TNS V1-V3)
SELECT TOWNER, TNAME, NAME, LENGTH, PRECISION, SCALE, TYPE, ISNULL, CONNAME, COLID, INTCOLID, SEGCOLID, COMMENT$, DEFAULT$, DFLTLEN, ENABLED, DEFER, FLAGS, COLPROP, ADTNAME, ADTOWNER, CHARSETID, CHARSETFORM, FSPRECISION, LFPRECISION, CHARLEN, TFLAGS, 100 FROM SYS.EXU8COL
WHERE TOBJID = :1 ORDER BY INTCOLID
SLOW:
elapse_time: 8264.16
executions: 124,662
Module: exp@Oracle1 (TNS V1-V3)
SELECT COLNAME, COLNO, PROPERTY, NOLOG FROM SYS.EXU10CCL
WHERE CNO = :1 ORDER BY COLNO
elapsed_time: 3877.78
executions: 38,813
Module: exp@Oracle1 (TNS V1-V3)
SELECT TOWNER, TNAME, NAME, LENGTH, PRECISION, SCALE, TYPE, ISNULL, CONNAME, COLID, INTCOLID, SEGCOLID, COMMENT$, DEFAULT$, DFLTLEN, ENABLED, DEFER, FLAGS, COLPROP, ADTNAME, ADTOWNER, CHARSETID, CHARSETFORM, FSPRECISION, LFPRECISION, CHARLEN, TFLAGS, 100 FROM SYS.EXU8COL
WHERE TOBJID = :1 ORDER BY INTCOLID
I use the following export command for each schema:
$ORACLE_HOME/bin/exp user/pass file=somefile.dmp owner=$SCHEMA log=somelog.log buffer=9000000
I have an Oracle Standard edition 11.1.0.7 database on 64bit Linux with a 7GB SGA. I currently export (I use exp not datapump because datapump is a lot slower and we can't use parallel processing features of datapump on a standard edition database) approx 200 schema's each night. The export normally takes 1 hour 50 minutes which is approximately 2 schema's exported every minute. When the exports run slowly each export takes almost 2 minutes to complete.
The database has about 20 GB data and 50 GB indexes. The database has also approx 500 connections via toplink connection pools from 8 application servers.

SQL & PL/SQL :: How Oracle Manages Multiple Sessions In A Database Performing DML
Feb 25, 2011I was just wondering how Oracle manages multiple sessions in a database performing DML. I believe this is related to 'Read Consistency' and I tried to search for the same but could not get any satisfactory online documents.
CASE 1:
user A logs in to a database1
issues select on table A and then inserts 4 rows
user B logs in to databse1
issues select on table A and then inserts 5 rows
issues rollback
user C logs in to a database1
issues select on table A and then inserts 6 rows
issues commit
How many rows can user C see in the table A when he issues select?
CASE 2:
user A logs in to a database1
issues select on table A and then inserts 4 rows
user B logs in to databse1
issues select on table A and then inserts 5 rows
user C logs in to a database1
user B issues rollback
user C issues select on table A and then inserts 6 rows
issues commit
How many rows can user C see in the table A when he issues select?
NOTE: All the users are currently logged in to the same database and none has logged out.
Server Administration :: Database Sessions - Setting Value Of Parameter
Mar 26, 2013I have a simple question about database sessions. The value of parameter "sessions" is set to 500 and the users connect to database through an application server(Jboss). There are more than 500 users connect to the database through application.
My question is, how more than 500 users can connect to the database without any issue, if we set the value of "sessions" parameter to 500?
Application Express :: 4.2 New Database Sessions Per Report Region?
Nov 22, 2012Does version 4.2 create a new db session for each report run on a page?
The reason I ask is we have a page with 4 report regions, each querying a global temporary table that is populated in a 'Before Regions' page process. The first report displays the correct data, but the others return 'No Data Found' and it is because the Global Temporary Table has been cleared out following the first report. This did not happen in 4.1.
I know we should be using Apex Collections, and we will in future, but time is at a premium to get this live
Slow Database - V$session Has Lots Of Active Sessions With 00 As Sql-address?
Oct 1, 2012Server:
Windows 2008 R2 x64
Oracle Database 11g Release 11.2.0.1.0 Standard Edition
I recently applied the Oracle® Database Server Version 11.2.0.1 Patch 16 I have several databases running on this box with the same application.Since then I've had lots of customers complaining about slow systems. The server has plenty of RAM availableI also have several other servers all on the same versions, same patch, running the same application with no issues.
Looking at v$session there are often lots of active sessions that have a sql_address of "00". I've never seen this before and I regularly look at v$session, as you can see for below these have been running for a while. The sessions do drop off but I am at a loss as to what is happening.
select username, last_call_et, sid, serial#, user#, status, sql_address, sql_hash_value
from v$session
where username is not null and status = 'ACTIVE'
order by last_call_et desc, sid

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.

Security :: Limit Sessions Per User In RAC

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

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.
