Depends on what you already have on your PC. If you have Microsoft Visio, it will work. Also If you are using Sql Server 2000 for you DB, it has a diagram tool in it. Look at the apps you have before you try to find a third party program.
Although there are a number of ways to do this in a single SQL statement, it’s best to use a cursor loop, since any such SQL statement would rely on order of execution, and that’s called a “pornographic specification”, since it can be version-dependent. Here’s how I’d do it: Assuming: CREATE TABLE myTable( major INTEGER, [...]
The following rudimentary script will show you the basics. You can expand on this to show what you need. select b.sid, b.username, a.sql_text from v$sqlarea a, v$session b where a.address=b.sql_address Oracle’s Enterprise Manager ‘Top Sessions’, ‘Top SQL’ provides a good gui interface.
Have a look in the oracle/admin/[sid]/bdump directory at the alert_[sid].log file. Should see entries of when a database is started or shutdown.
Actually, Oracle light is meant to do excatly what you are describing. A low maintenance db on devices that travel. http://download-east.oracle.com/docs/cd/B19188_01/doc/B15921/toc.htm Take a look. For details on what Oracle supports of replication (which is the term Oracle uses for DB-DB sync – not DB-user) check out the RDBMS manual for replication. There are restrictions based [...]
I seem to remember this behaviour when you don’t have the correct environment set up. $ORACLE_HOME amongst others must be set up. Talk to your DBA, there should be a script to set up all your necessary environment.
SAP has a OS/DB migrations guide/checklist and a go-live check that has to be performed before you go live on the new system. I have done this several time for different DB and OS. Seeing that this will be a hetrogenius migration you can run the R/3 Inst. on the DEV system and export the [...]
Have you verified that you have the latest DAO drivers? For development purposes could you make a start with ODBC?
I assume from your question, that you’re not using Java within Oracle. You’re “just” using JDBC to access Oracle. In case of performance problems, it important that you identify the wait causes. Is it the DB that’s busy, or your frontend application that’s slowing things down – or a combination. Reasons for performance problems are [...]
One way (maybe the only way) would be to recreate the table. You could do that by first creating the new table with the columns in the order you want them. Then insert the rows of the old table into the new table (using “Insert into table2 (col1,col2..) select col1,col2.. from table1″). Then rename or [...]
Hi, First check, if the 8i database is mounted. If the database is not mounted use SVRMGRL oracle command to mount the database. If database is mounted then check access to the database using userid – ‘sys’ or ‘system’
Do you have Oracle s/w for installing the client on the linux box? That’s the first step. Then is configuring the tnsnames.ora, listener.ora and sqlnet.ora files (help is around, such as http://www.orafaq.com/faqnet.htm). (I assume you ping the box, if not, you should get that to work first) You will need to ask for the database [...]
If it is an extranet: A) You need to set up a public IP for the server. You can do that in your firewall (it will do the NAT translation of the public IP to the internal network IP of the server) B) In your firewall, you need to open port 8000 for that public [...]
It’s best to know both. Working as a consultant, I’ve had to write a lot of code, and rescue a lot of projects in trouble. I’ve never had to fix bad Java code; just add to it. VB code often involves a lot of fixing. Either way, I have to know both. Where’s the future? [...]
There’s not a hard cutoff line. Having a changing element as a part of a key, primary or not, causes work. The only question is, are you better off indexed or not. You can work out the theory for weeks, or you can try the application with and without the index. Note also that having [...]
I also do this type of transactions. I don’t think it hurts the database to connect/disconnect. I have found that you have to weigh the problems of each option. The problem with connect/disconnect is that there is a certain amount of wait time for the application to make the connection. If the wait time is [...]
Hi, When optimizer values are changed for the instance and tables are analyzed, it takes the server sometime to settle down. Esp. if the tables are being analyzed after a long time. The parser has to generate new explain plan which may or may not be the best plan (depending on the options used with [...]
Hi, Can u specify which database severs ur trying to merge.
Analytic functions are cool; it is however tricky to get them right. The query skeleton below should work for you: select (select count(1) from tab_name where trans_date between sysdate – 7 and sysdate) seven_days_count, (select count(1) from tab_name where trans_date between sysdate – 180 and sysdate) six_month_count from dual ; ++ Olu
Hi, If you need to aggregate it in 90 days lot ,then just create MVs in oracle with your periodicity required, all further process can be continued from the MVs rather than complex scripts to extarct and calculate. If you are looking more please the full requirement. Regards Deva.
