3 Job Admin Services

This chapter discusses the Job Admin Services.

Job Admin RESTful Services

Job Admin provides below RESTful services. These services are secured with SSL and basic authentication.

• Batch Service - Ability to start/stop/restart, check status, and so on of jobs. This service is typically used by the BDI Process Flow engine.

• Receiver Service - Ability to stream data from one system to another system. This service is used by the Downloader-Transporter job.

• System Setting Service - Ability to view, change system settings, and credentials. Refer to Appendix D for details on System Setting REST resources.

• Data Service - Ability to get data set information using job information such as job name, execution id or instance id.

• Telemetry Service - Ability to get job metrics for jobs that ran between fromTime and toTime.

Receiver Service

The Receiver Service is a RESTful service that provides various endpoints to send data transactionally. Receiver Service is part of Job Admin. Receiver Service uploads the data to either database or files. By default, the Receiver Service stores the data in the database. It stores data as files and keeps track of metadata in the database. The Receiver Service also supports various merge strategies for merging files at the end. The Receiver Service is used by the Downloader-Transporter job to transmit data from source to destination.Seed data for Receiver Service is generated during design time and loaded during deployment of the Job Admin application.

BDI_RECEIVER_OPTIONS

The Receiver Service options can be configured at interface level.

Table 3-1 Receiver Options

Column	Type	Comments
ID	NUMBER	Primary key
INTERFACE_MODULE	VARCHAR2(255)	Name of the interface module
INTERFACE_SHORT_NAME	VARCHAR2(255)	Name of the interface
BASE_FOLDER	VARCHAR2(255)	This is the base folder for storing files created by Receiver Service. Receiver Service creates a subfolder ”bdi-data” under base folder. Base folder can be changed from ”Manage Configurations” tab of Job Admin GUI.
FOLDER_TEMPLATE	VARCHAR2(255)	Folder template provides the folder structure for storing files created by Receiver Service.Default value is ”${basefolder}/${TxId}/${TId}/${BId}/”. TxId - Transaction IdTId - Transmission IdBId - Block IdThis value can't be changed.
MERGE_STRATEGY	VARCHAR2(255)	The strategy for merging files. The default value is ”NO_MERGE”. The valid values are NO_MERGE, MERGE_TO_PARTITION_LEVEL, and MERGE_TO_INTERFACE_LEVEL.MERGE_TO_PARTITION_LEVELMerges all files for that partition and creates the merged file in ”${TId}” folder.MERGE_TO_INTERFACE_LEVELMerges all files for interface and creates the merged file in ”${TxId}” folder.MERGE strategies are only supported in cases where the Uploader is not used.

Endpoints

If ”mergeStrategy” is set to ”MERGE_TO_PARTITION_LEVEL” or ”MERGE_TO_INTERFACE_LEVEL”, then it merges the files and creates the merged file(s) at the appropriate directory. It creates an entry in the BDI_UPLDER_IFACE_MOD_DATA_CTL table so that Uploader job can pick up the data.

HTTP Method: POST

Path: receiver/endTransaction/{transactionId}/{sourceSystemName}/{interfaceModule}

Sample Response
 
{
        ”receiverTransactionId”: ”1”,
        ”transactionId”: ”Tx#1”,
        ”sourceSystemName”: ”RMS”,
        ”interfaceModule”: ”Diff_Fnd”,
        ”sourceSystemId”: ””,
        ”dataSetType”: ”FULL”,
        ”sourceSystemDataSetReadyTime”: ””,
        ”dir”: ””,
        ”fileName”: ””,
        ”receiverTransactionStatus”: ””,
        ”receiverTransactionBeginTime”: ””,
        ”receiverTransactionEndTime”: ””    
}

Uploader Interface Module Data Control Table

The BDI_UPLDER_IFACE_MOD_DATA_CTL table acts as a handshake between the downloader and uploader jobs. When the downloader-transporter job calls endTransaction on Receiver Service, the Receiver Service creates an entry in this table if it successfully received data and created files.

An entry in this table indicates to the uploader job that a data set is ready to be uploaded.

BDI_UPLDER_IFACE_MOD_DATA_CTL

Table 3-2 Module Data Control

Column	Type	Comments
UPLOADER_IFACE_MOD_DATA_CTLID	NUMBER	Primary key
INTERFACE_MODULE	VARCHAR2(255)	Name of the interface module
REMOTE_TRANSACTION_ID	VARCHAR2(255)	Transaction Id of Downloader-Transporter job
SOURCE_DATA_SET_ID	NUMBER	NUMBER ID of the source data set
SRC_SYS_DATA_SET_READY_TIME	TIMESTAMP	Source Data Set Ready Time
DATA_SET_TYPE	VARCHAR2(255)	Type of data set (FULL or PARTIAL)
DATA_SET_READY_TIME	TIMESTAMP	Time when data set was available in the outbound tables
DATA_FILE_MERGE_LEVEL	VARCHAR2(255)	Merge level for the files (NO_MERGE, MERGE_TO_PARTITION_LEVEL, MERGE_TO_INTERFACE_LEVEL)
SOURCE_SYSTEM_NAME	VARCHAR2(255)	Name of the source system (for example RMS)

Receiver Side Split for Multiple Destinations

If there are multiple destinations that receive data from a source, one of the options is to use the Receiver Service at one destination to receive data from the sender and then multiple destinations use the data from one Receiver Service to upload to inbound tables. The requirements for the Receiver Side Split are such that:

• The Receiver Service database schema is shared by all the destinations

• The File system is shared by all destinations

The performance of BDI can be improved by using the receiver side split if there are multiple destinations.

Batch Service

End Points for CRUD operations on Job XML

End points have been added to Batch Service to allow CRUD operations on Job XML.

CREATE Job XML

This end point creates an entry in BDI_JOB_DEFINITION table. It will throw an exception if job already exists.

HTTP Method: PUT

Path: /resources/batch/jobs/job-def-xml/{jobName}

Inputs:

Job Name (e.g. Diff_Fnd_ExtractorJob)

Job XML - It has to be valid XML that conforms to Job XML schema. The value of "id" in the XML should match "jobName" path parameter.

Update Job XML

This end point updates an entry in BDI_JOB_DEFINITION table. It will update if job is not in running state. This end point throws an exception if job doesn't exist in the table.

HTTP Method: POST

Path: /resources/batch/jobs/job-def-xml/{jobName}

Inputs:

Job Name (e.g. Diff_Fnd_ExtractorJob)

Job XML - It has to be valid XML that conforms to Job XML schema. The value of "id" in the XML should match "jobName" path parameter.

Delete Job XML

This end point deletes an entry in BDI_JOB_DEFINITION table. It will delete if job is not in running state and if there is no history in batch database.

HTTP Method: DELETE

Path: /resources/batch/jobs/job-def-xml/{jobName}

Inputs:

Job Name (e.g. Diff_Fnd_ExtractorJob)

Delete Job History

This end point deletes history for a job from batch database. It will delete history if job is not in running state.

HTTP Method: DELETE

Path: /resources/batch/jobs/{jobName}

Inputs:

Job Name (e.g. Diff_Fnd_ExtractorJob)

Bulk API for Batch Job CRUD Operations

ReST Endpoints have been introduced for Bulk create/update and Delete of Jobs in BDI/JOS Job admin application. There were existing end points to create/update/delete the individual jobs but it would be a great effort to use them sequentially for high number of jobs. A single end point service which can be used to take care of bulk create OR update operation for new job set has been added. Another end point for deleting multiple jobs has been added. Both the end points provide Job Level success and failure response for Create/Update/Delete.

End point for create/update job definitions

Error Response:

There would be individual calls for each job xml, if any job fails we can still process the next job and can show the list at the end for failed and success jobs.

Possible issues could be:

• Cannot update job XML if that job is running.

• Cannot create/update the Job if job id was not found in input job xml.

• Cannot create/update the Job if input job xml is not readable/parsable.

Configuration of Job Admin

During the deployment of Job Admin, seed data gets loaded to various tables. Seed data files are located in the bdi-<app>-home/setup-data/dml folder. If seed data is changed, Job Admin need to be reinstalled and redeployed. For loading seed data again during the redeployment, LOADSEEDDATA flag in the BDI_SYSTEM_OPTIONS table need to be set to TRUE.

Jobs

The following job properties can be changed to improve the performance of the jobs.

Item-count - Number of items read by a job before it writes. Default size is 1000.

fetchSize - Number of items cached by JBDC driver. Default size is 1000.

Receiver Service

The Receiver Service allows maximum number of blocks for transaction based on the following system option in BDI_SYSTEM_OPTIONS table.

receiverMaxNumBlocks - Default value is set to 10000

Seed data need to be changed to update the maximum number of blocks for the Receiver Service. To update the seed data, set the LOADSEEDDATA flag to TRUE, reinstall and redeploy Job Admin. The Value of the LOADSEEDDATA flag can be changed from the Job Admin Manage Configurations Tab.

Job Admin Customization

During the deployment of Job Admin, seed data is loaded to various tables. Seed data files are located in the bdi-edge-<app>-job-home/setup-data/dml folder. If seed data is changed, Job Admin must be reinstalled and redeployed. In order to load seed data again during the redeployment, the LOADSEEDDATA flag in the BDI_SYSTEM_ OPTIONS table must be set to TRUE.

During the deployment, Job XMLs get loaded to BDI_JOB_DEFINITION table. Job XML files are located in the "jos-job-home/setup-data/META-INF/batch-jobs" folder. If job xmls are changed, Job Admin must be reinstalled and redeployed. In order to load job xmls during redeployment, the LOADJOBDEF flag in the BDI_SYSTEM_OPTIONS table must be set to TRUE.

Note: Restart of job does not load job definition from the BDI_JOB_DEFINITION table. Java Batch loads job xml from JOBSTATUS table during the restart of a job. If there is an issue with Job XML, job needs to be started after fixing the job XML.

Throttling

Throttling is the capability of regulating the rate of input for a system where output rate is slower than input.

Java Batch runtime will not allow to run multiple instances of a job at same time, it will say job is currently running and fail the job. There can be only one instance of a job at any time (unless the job parameters are different).

Throttling is introduced to address the issue caused when there are many job start requests at the same time. In order to honor the throttle limits "throttleSystemLimit" is introduced to make sure the system never runs more than the throttle limit for the group and the system.

Three new tables are added to job schema to handle throttling, these are BDI_GROUP, BDI_GROUP_LOCK, BDI_GROUP_MEMBER.

Table 3-6 BDI Group

Column	Type	Comments
GROUP_ID	NUMBER	Primary Key
APP_TAG	VARCHAR2(255)	Name of the application
COMMENTS	VARCHAR2(255)	Comments
GROUP_ATTRIB_NAME_1	VARCHAR2(255)	Name of the group attribute ex - THROTTLE_JOBS_IN_SAME_GROUP
GROUP_ATTRIB_NAME_2	VARCHAR2(255)	Name of the group attribute
GROUP_ATTRIB_NAME_3	VARCHAR2(255)	Name of the group attribute
GROUP_ATTRIB_NAME_4	VARCHAR2(255)	Name of the group attribute
GROUP_ATTRIB_NAME_5	VARCHAR2(255)	Name of the group attribute
GROUP_ATTRIB_VAL_1	VARCHAR2(255)	Value of the group attribute
GROUP_ATTRIB_VAL_2	VARCHAR2(255)	Value of the group attribute
GROUP_ATTRIB_VAL_3	VARCHAR2(255)	Value of the group attribute
GROUP_ATTRIB_VAL_4	VARCHAR2(255)	Value of the group attribute
GROUP_ATTRIB_VAL_5	VARCHAR2(255)	Value of the group attribute
GROUP_NAME	VARCHAR2(255)	Name of the group

Table 3-7 BDI Group Member

Column	Type	Comments
GROUP_MEMBER_ID	NUMBER	Primary Key
APP_TAG	VARCHAR2(255)	Name of the application
GROUP_ID	NUMBER	Group id
MEMBER_NAME	VARCHAR2(255)	Name of the job
MEMBER_TYPE	VARCHAR2(255)	Type of the member ex - job

Table 3-8 BDI Group Lock

Column	Type	Comments
LOCK_ID	NUMBER	Primary Key
APP_TAG	VARCHAR2(255)	Name of the application
GROUP_NAME	VARCHAR2(255)	Name of the group

Prerequisite: In weblogic console, make sure the job admin data source has "Supports Global Transactions" and "Logging Last Resource" checked in the Transaction tab.

Example on how throttling is handled at runtime:Group1 <--(job1, job2, job3)-Throttle value 3 Group2 <-- (job1, job2) - Throttle value2

Step1:

Start job1, job2, job3 from process1, process2, process3 respectively. All 3 start running.

Step2:

Then start again process1 and process2. Both job1 and job2 get throttled.

There can be only one instance of a job at any time (unless the job parameters are different).
