3. Concurrent Program Parameters :
The 3rd step in defining concurrent program is to define the parameters. To do this, click on the Parameters button as shown at the bottom the form in figure 4. The following screen (figure 5) is displayed when you click on parameters button. This screen is used to define the parameters in the concurrent program.

Figure 5. Parameter Window

Field Description

i) Program – will be defaulted from Concurrent Program

ii) Application – will be defaulted from Concurrent Program

iii) Conflicts Domain - Enter the parameter which will hold the value of the conflict domain of the program.

iv) Security Group - This field is for HRMS security only.

v) Seq – Enter sequence number for the parameter

vi) Parameter – name of the parameter, will be displayed in parameter entry screen

vii) Description – description about the usage of the parameter

viii) Enabled – check box to enable or disable the parameter. Disable a parameter when you don’t want to use it.

ix) Value set – enter the name of the value set which you want to use to validate the value enter in the parameter field.

x) Description – will be defaulted from value set definition

xi) Default Type – choose the default type for the default value of the parameter. Possible default types are

Constant : The default value can be any literal value.
Profile : The default value is the current value in the user profile option defined in the Default Value field. Use the profile option name, not the end–user name. You do not need to include $PROFILE$.
SQL Statement : The default value is determined by the SQL statement you defined in the Default Value field.
Segment : The default value is the value entered in a prior segment of the same parameter window.

xii) Display size – Enter the field length in characters for this parameter. The user sees and fills in the field in the Parameters window of the Submit Requests window.

xiii) Token - For a parameter in an Oracle Reports program, the keyword or parameter appears here. The value is case insensitive. For other types of programs, you can skip this field.

4. Incompatible Programs Window :

To navigate to this form, click on the Incompatibilities button on the bottom of the form shown in figure 4. This window is used for defining the incompatibilities of the concurrent program. Identify concurrent programs that should not run with your concurrent program as they might interfere with its execution.

Figure 6. Incompatibilities Form

Field Description

i) Program – Defaulted from Concurrent Programs Window

ii) Application – Defaulted from Concurrent Programs Window

iii) Application – Application of the concurrent program which is incompatible to the defined concurrent program.

iv) Name – Name of the concurrent program which is incompatible to the defined concurrent program.

v) Scope – Used to identify if concurrent program is incompatible if the program or also with its child requests.

vi) Type - Enter Domain or Global. If you choose Domain, the incompatibility is resolved at a domain-specific level. If you choose Global, then this concurrent program will be considered globally incompatible with your concurrent program, regardless of which domain it is running in.

5. Session Control :

To navigate to this form, click on the Session Control button on the bottom of the form shown in figure 4. This is a new functionality given in 11.5.10 to control the database session while executing concurrent program using following three parameters. The form would look like as shown in figure 7.

Figure 7. Session Control Form

Field Description

i) Consumer Group – resource consumer group of the concurrent program can be specified. A resource consumer group defines a set of users who have similar resource usage requirements. An overall resource plan specifies how resources are distributed among the different resource consumer groups. Resource consumer groups and resource plans provide a method for specifying how to partition processing resources among different users.

ii) Rollback Segment – Rollback segment specified here would be used instead of the default rollback segment. If you specify a rollback segment here, your concurrent program must use the APIs FND_CONCURRENT.AF_COMMIT and FND_CONCURRENT.AF_ROLLBACK to use the specified rollback segment.

iii) Optimizer mode - Optionally specify an optimizer mode. You can choose ALL_ROWS, FIRST_ROWS, Rules, or Choose. You would specify an optimizer mode only for a custom program that may not perform well with the default cost-based optimizer (CBO) and needs tuning. You can use a different optimizer mode until your program is tuned for CBO.
