2E Modernization Workshop

Database Modernization with SQL

Database Modernization with SQL A. Set up the Model Values

1. YCHGMDLVAL = CMINSMDL2 a. YCHGMDLVAL MDLVAL(YSQLLIB) VALUE(CMINSMDL2)

2. YDBFGEN = *DDL a. YCHGMDLVAL MDLVAL(YDBFGEN) VALUE(*DDL)

3. YSQLLEN = 25 a. YCHGMDLVAL MDLVAL(YSQLLEN) VALUE(25)

4. YSQLVNM = *LNG (Use the long names of the CA 2E objects in the model along with the DDS or implementation names.)

a. YCHGMDLVAL MDLVAL(YSQLVNM) VALUE(*LNG)

5. YCHGMDLVAL = *NO


a. YCHGMDLVAL MDLVAL(YSQLCOL) VALUE(*NO)Compile the file

6. Look at the DDS for file “DDS File to SQL” file to verify that the code is DDS code.

7. Enter a G on the Physical File for “DDS File to SQL” 8. Look at the code again. This time, the generated code for the physical file should be similar

to below and written in SQL/DDL


9. To generate the Logical files: a. Z into the Update Index. b. Set the Data access method to T for Table. This will suppress creating a View.


c. Once the Data access method is set, generate the source for the logical. d. View the source to verify it has been generated as SQL/DDL e. Report steps a, b, c and d for all logical files for this file. f. Go to the Generate/Create screen and finish the create step. You are now creating

type YSQL.

g. Run the program without generating or compiling it.

h. You should end up with the program functioning as it did before.

Quick Modernization with Web Option

Quick Modernization with Web Option A. Add the Screen ID

a. Select the header/footer that contains the Screen ID.

B. Verify that the Screen ID has been added.

C. Gen and create your function. D. Generate the HTML

E. Run the web application.

a. http://devi5.cmfirsttech.com:4630/web2e b. Call mlslib/inswo c. Locate your screen.

Modern Integrations with Web Services


A. Create a Web Service to bring back a record. 1. Create three basic functions.

a. SRV Get Person (USERID) PGM b. SRV Get Person (USERID) MOD c. SRV Get Person (USERID) SPS d. SRV Get Person(USERID) WS – Optional based on method of WS Deployment.

2. Set up the PGM.

a. Set the HLL to RPG. We could use another language but in this demo RPG will be

used.

b. The parameters. i. Input – Person ID ii. Output – All fields except the audit stamp fields. – Create an array with

these values.

c. Set up the business logic.


i. Call a retrieve object to return all the fields for person except for the audit stamp fields.

ii. Be sure to put in an exit program.

3. Configure the MOD program

a. Set the HLL to RP4 b. Set the Object Type to MOD

i. To do this, enter a T at ? and the Object Type will change to a module. c. Check the Compile Overrides

i. The Compiler Overrides for the PGMINFO parameter to ii. PGMINFO(*PCML *MODULE)

d. Set the Parameters

i. Input parameters – If you use an access path or array, all parameters must be used.

ii. Output parameters – Create an array with the fields you will return.


e. Add code to the service program

i. Call the program. ii. Add an exit program to return the *return code.

4. Configure the SPS program

a. Add the module just created to this service program.


b. Press F6 to add the module and then select the module from the existing list of modules.

5. Install the Web Service using the IBMi Web Services Manager a. Open up the Web Services manager

i. http://devi5.cmfirsttech.com:2001/HTTPAdmin ii. Select Application Services

b. Click on the Deploy button. c. Click Next until you are at the Deploy Web services screen that asks for the program

and library.


d. Enter the library: CMINSGEN2 e. Enter the Service program name: (This is the SPS you created) f. Click Next. g. Enter the name and description for the web service.

i. The Service name cannot have blanks between words. ii. Service description should point back to the service program name you

created.

h. Click Next


i. Enter the type of parms for the Service.

j. Click next until the Service is complete and you are back an the manage Services screen.


6. Test the web service with SOAPUI. a. Create a test project


b. Enter the Project Name and the WSDL URL.


c. Double click on the Request 1 for testing.

d. Enter any necessary parameters and press the green go arrow.


B. Create Web Service to Change values

1. Create three basic functions.

a. SRV Get Person (USERID) MOD b. SRV Get Person (USERID) PGM c. SRV Get Person (USERID) SPS


d. WS is optional 2. Build the CTL – Same options as in the first web service.

a. Set the HLL to RP4 b. Set the Object Type to MOD

i. To do this enter a T at ? and the Object Type will change to a module. c. Check the Compile Overrides

i. The Compiler Overrides for the PGMINFO parameter to PGMINFO(*PCML *MODULE)

3. Build the PGM

a. Set the Input Parameters. i. Key – User ID ii. Inputs – all fields except audit stamp fields.

b. Optional, the target can be RP4, RPG, COBOL or CBI c. Add code in the program to change the user information.

4. Build the SPS

a. Add the module using the IBM Deployed Services tool. b. Z into the function and enter an M on the option field. c. F6 to select and add the module to the Service Program.

7. Deploy the Web Service

a. Open to tools if it is not open: http://devi5.cmfirsttech.com:2001/HTTPAdmin b. Follow the sets in section 5 above.

8. Test the web service with SOAPUI.

B. Create a Web Services to bring back a List of Records.

1. Create three basic functions.


a. SRV List Persons (USERID) MOD b. SRV List Persons (USERID) PGM c. SRV List Persons (USERID) SPS d. WS is optional e.

2. Build the PGM a. Set the Input Parameters.

i. Key – User ID ii. Inputs – all fields except audit stamp fields.

b. Optional, the target can be RP4, RPG, COBOL or CBI

3. Add code in the program to get a list of user. a. Initialized the Array. Create a loop that will initialize all 30 elements of the output

array. b. Build the internal data array by reading the person table and add each person to the

array. c. Build the output array list. Read through the data array and add each element to

the output array.


d. In the look write the data to the output array

e. Set the return code and exit the program.

4. Build the Module – Same options as in the first web service. a. Set the HLL to RP4 b. Set the Object Type to MOD

i. To do this enter a T at ? and the Object Type will change to a module. c. Check the Compile Overrides

i. The Compiler Overrides for the PGMINFO parameter to PGMINFO(*PCML *MODULE)

d. The Module calls the PGM.


5. Build the SPS a. Add the module using the IBM Deployed Services tool. b. Z into the function and enter an M on the option field. c. F6 to select and add the module to the Service Program.

9. Deploy the Web Service

a. Open to tools if it is not open: http://devi5.cmfirsttech.com:2001/HTTPAdmin b. Follow the steps in the previous exercises to deploy the web service.

10. Test the web service with SOAPUI.
