Environmental Challenges Combining AS/400 data with HP-UX data

For reporting from Windows Metadata – Table names shared

16 AS/400 database 64 HP-UX Schemas

Standardized Metadata across platforms

Metadata Names by Default

AS/400 Metadata

HP-UX Metadata

Metadata Names Shared

•Standardized naming conventions

•User Friendly Metadata

Available Options Maintain 80 sets of Metadata per Table

Maintain 80 dataflows per iDM job Share Metadata and loop through databases

Solution: Share Metadata and loop through databases

Reading the System Connections

EX PULL_ACTIVE_DBS_FROM_PHARMACY DM_FOLDER=&DM_FOLDER -SET &NUM_CONNECTIONS = &LINES;

Use Focexec to pull the system information needed:

•Active –vs- in-active

•Hold output as ALPHA

Set up Loop controls

-IF &NUM_CONNECTIONS = 0 THEN GOTO NO_CONNS; -SET &LOOP_CNT = 1;

Reading the System Connections

Read in the information from the ALPHA HOLD file created using the Focexec above.

Point to AS/400 Sub System

Since source systems are on the sub servers we need to create the ACX files on those sub servers.

Execute the iDM Data Flow to pull the AS/400 data, passing the “company ID” as a parameter.

Parameter as Filter

Process HP-UX

ENGINE SQLEDA SET HP-UX

-REMOTE BEGINEX WRITE_ACCESS_FILE SYS_CONN=&SYS_CONN-REMOTE END

EX CMASAP REQ_NAME=HP-UX_data_flow, CM_ASYNC=OFF, PARMS="SYS_CONN=&SYS_CONN"

Point to HP-UX Sub System

Since source systems are on the sub servers we need to create the ACX files on those sub servers.

Execute the iDM Data Flow to pull the HP-UX data, passing the system connection information.

Parameter as Transformation

Final Step -INCR_LOOP-SET &LOOP_CNT = &LOOP_CNT + 1;-IF &LOOP_CNT LE &NUM_CONNECTIONS THEN GOTO

START_PROC ELSE GOTO DONE;

Increment the Loop counter and test to see if there are more connections to process.
