Issues of Oracle Database Connection to TOAD

Connections to Oracle database via TNS are bit of a painful until you get all the components in the TNS configured correctly. We generally get different types of errors when we try to connect the DB using TOAD.  Usually we get Host, Port & Service Name in the TNS Entry but SID is excluded from it. But if we supply the SID information instead of service name it gets connected easily. If we get the SID for the database we can easily connect to the DB using TOAD.

Solution of Oracle Database Connection by TOAD:

We can connect to any database instance using TOAD by the following steps:

1.       Connect to the database using SQL*Plus as below
Ø  User Name: ORACLE_USER
Ø  Password: ORACLE_password1
Ø  Host String: 156.14.200.90:1542/VISSVC(host:port/Service Name)
Ø  Or conn ORACLE_USER/ORACLE_password1@156.14.200.90:1542/ORAVISSVC (Conn user/password@host:portNumber/ServiceName)

2.       Execute the following script
Ø     SELECT instance_name
            FROM v$instance;
-----------------
ORAVIS_1      

3.       Note the instance name from above script

Row splitting on BI Publisher report with excel output

-
Issue: ------ The BI Publisher Report with excel output is splitting lines into separate rows for the same record. Findings: --------- As per my analysis, carriage returns on the field is one of the reason for row splitting on BI Publisher Report. Oracle BI Publisher report output generator cannot identify those non-human readable carriage returns. I continued my analysis and found out there are similar issue with some others fields also and Swiss characters are not creating this issue.  I tried to create a prototype to replace those non-human readable carriage returns symbol with spaces. Finally the prototype has been successfully created for both the fields in test instance. Hopefully this solution has been successfully fixed the row splitting issue. Solution: Edit the data definition XML file and for each field with carriage return char with space replace with following: TRANSLATE(TRANSLATE(htv.TCRD_COMMENT_TEXT, CHR(10),' '), CHR(13),' ')
