1 Introducing the Oracle Business Intelligence Discoverer EUL Command Line for Java

This chapter introduces the OracleBI Discoverer EUL Command Line for Java, and contains the following topics:

What is the OracleBI Discoverer EUL Command Line for Java?

The OracleBI Discoverer EUL Command Line for Java is a set of text based commands that enable you to create and manipulate Discoverer EULs.

Note: You use Heterogeneous Services to connect to non-Oracle databases, although the EUL is stored in the Oracle database. For more information about using non-Oracle databases, see Oracle Heterogeneous Connectivity Administrator's Guide.

The Discoverer EUL Command Line for Java runs in a Java environment, which means that you can run it from any Java-compatible platform (e.g. Windows, UNIX, Linux). For example, you might want to refresh (or patch) an EUL from a UNIX machine.

The figure below shows three different ways in which you can manipulate Discoverer EULs:

Description of Figure 1-1  follows
Description of "Figure 1-1 Discoverer interfaces to the Discoverer EUL"

Notes:

What are the differences between the OracleBI Discoverer Administrator Command Line Interface and the Discoverer EUL Command Line for Java?

Much of the Discoverer EUL Command Line for Java is compatible with the OracleBI Discoverer Administrator Command Line Interface. If you have commands and scripts written for the OracleBI Discoverer Administrator Command Line Interface, you can easily convert them to run on the Discoverer EUL Command Line for Java.

The OracleBI Discoverer Administrator Command Line Interface and the Discoverer EUL Command Line for Java differ as follows:

What is a Discoverer EUL Command Line for Java command?

A Discoverer EUL Command Line for Java command is an instruction that manipulates a Discoverer EUL in some way. For example:

What is a Discoverer EUL Command Line for Java command modifier?

A Discoverer EUL Command Line for Java command modifier is an instruction that qualifies or refines a command. For example:

What privileges do you require to use the Discoverer EUL Command Line for Java?

To use the Discoverer EUL Command Line for Java, the database username that you use to connect to a database must have the following database privileges:

The database username also requires a default tablespace, and a quota set on the default tablespace. For more information about granting privileges, see Oracle Business Intelligence Discoverer Administration Guide.

How to run a Discoverer EUL Command Line for Java command

You can run the Discoverer EUL Command Line for Java in two ways:

Notes

How to type commands directly at a command prompt

You might type commands directly at a command prompt when you want to patch an EUL from a UNIX machine.

To type a command directly at a command prompt:

  1. Open a command prompt (e.g. a UNIX command prompt).

  2. Type a command directly at the command prompt.

    For example, to refresh folders called Sales1 and Sales2, type the following (see figure below):

eulapi -connect jchan/12345@my_database -refresh_folder Sales1 -refresh_folder Sales2

Description of Figure 1-2  follows
Description of "Figure 1-2 Using the Discoverer EUL Command Line for Java from a UNIX command prompt"

How to run commands stored in a command file

You might run commands stored in a command file when you want to perform a regular EUL update.

To run commands stored in a command file:

  1. Create a text file and type the commands into the text file (e.g. import.txt).

  2. Open a command prompt (e.g. a UNIX command prompt).

  3. Type the -cmdfile command at the command prompt followed by the name of a command file.

    For example, to run commands stored in import.txt, type the following:

eulapi -connect jchan/12345@my_database -cmdfile import.txt

For more information about command files, see "What is a command file?".

Notes

  • You can also run more than one command file by repeating the -cmdfile command. For example, to run commands stored in the text file login.txt, then commands in import.txt, type:

    eulapi -cmdfile c:\scripts\login.txt -cmdfile c:\scripts\import.txt
    

About troubleshooting the Discoverer EUL Command Line for Java

The Discoverer EUL Command Line for Java provides a log facility. Use the log facility to test commands without changing data (i.e. for impact analysis) and troubleshoot problems as follows:

-log <log file name> -log_only

These modifiers produce a log file showing whether problems occurred during command execution without changing the data. For more information, see "-log_only".

java EulCommandLine -connect jchan/12345@my_database -delete -folder Store 4 -log
Started <date and time>...
Deleting folder Store 4...
Element Store 4 cannot be deleted because it is used in a summary 
Completed <date and time>.

About using wildcards to identify EUL objects

When you use the Discoverer EUL Command Line for Java, you can use wildcards to specify groups of EUL objects that you want to manipulate. Wildcards are special characters that you use to substitute other characters. For example, you might want to import OLAP functions with names that begin with 'BI_'.

There are two wildcards that you can use:

You can use wildcards when you:

You can use wildcards with item names or identifiers. When you use wildcards, you append the command with the -wildcard modifier (for more information, see "-wildcard").

How to identify EUL objects using the percent wildcard:

  1. Use the percent sign (%) followed by the -wildcard modifier.

    For example, to delete all business areas with display names that begin with 'A':

eulapi -connect jchan/12345@my_database -delete -business_area A% -wildcard 

How to identify EUL objects using the underscore wildcard:

  1. Use the underscore (_) followed by the -wildcard modifier.

    For example, to delete all business areas with an identifier 'A', followed by any character, followed by 'C':

eulapi -connect jchan/12345@my_database -delete -business_area A_C -identifier -wildcard

Notes:

Examples of commands

Example 1

To delete the Sales folder and Sum1 summary from the Sales EUL, use the following command:

eulapi -connect jchan/12345@my_database -delete -folder Sales -summary Sum1 -eul Sales

Example 2

To refresh the Sales1 and Sales2 folders, use the following command:

eulapi -connect jchan/12345@my_database -refresh_folder Sales1 -refresh_folder Sales2

Example 3

To create an Applications Mode EUL in the database under user jchan and grant access using the Applications username and password apps/apps, use the following command:

eulapi -connect eul_owner:appsresp/appspwd -create_eul -apps_mode -apps_grant_details apps/apps -user jchan -password 123456

Notes:

What is a command file?

Command files are text files that contain one or more Discoverer EUL Command Line for Java commands. You use command files to run commands automatically without having to type them manually at a command prompt. If you are familiar with MS-DOS or UNIX, command files work in a similar way to MS-DOS batch files and UNIX script files.

Notes:

Examples of command files

Three example command files are described below:

  1. connect.txt contains '-connect jchan/12345@my_database'

  2. create.txt contains '-create_eul -log create.log'

  3. delete.txt contains '-delete_eul -log delete.log'

You can use these command files in different combinations as shown in the following examples:

Example 1

To connect to a database:

eulapi -cmdfile connect.txt

Example 2

To connect to a database, create an EUL, and store processing information in a log file:

eulapi -cmdfile connect.txt -cmdfile create.txt

Example 3

To connect to a database, delete an EUL, and store processing information in a log file:

eulapi -cmdfile connect.txt -cmdfile delete.txt
