System Description: IBM Aptiva, 128 MB RAM , P2 processor
First I installed the Oracle Personal database 9i release 2 ( 18.104.22.168.0) complete version(1.80 GB0) in the system. I followed the instructions provided at the following link
After the installation was complete, the above instructions asked me to create a account called "dbuser/oracle " using the database configuration assistant. This also went thru fine. However when i try to connect to the databse using SQL plus i can only login using the "dbuser/oracle " login account. I cant login using the "system/manager" account. However with the "dbuser/oracle" a/c i am able to create , and retrieve tables from the database.
After this I installed the oracle Developer Suite 9i release 2 on the system again following the instructions provided at the above link. The installation was successful. For the first time I tried to run a form based developer application. The system asked me if i wanted to log on to the database. I logged on the the database using the "dbuser/oracle". After this the Java Initiator process was also successful. But after this , when the browser was beginning to load the applet, a database connect dialog Box appears with the error message " ORA: 12560 TNS protocol adapter error". Ths connect dialog box shoe text string "DBUSER" in the name field. If i try to enter the "oracle" password , it again gives the same error message.
I know the minimum memory requirements r 256 MB and i am soon upgrading to 256 MB of RAM. Also let me know if I need to re install oracle database and DS after memory upgrade.
I am teaching assistant and prompt help ll be sincerely apreciated.
