User Interface Strategy - Administration

5

Provide a holistic view of your IMS databases from a single web interface. Dynamic, interactive graphs and charts provide you with a visual

representation of your sensor data. Integration with the Autonomics Director provides a list of policy

exceptions and recommended resolutions for all of your monitored databases.

All IMS Tools reports stored in the IMS Tools Knowledge Base can be searched, retrieved, and viewed as needed.

Prepare for the next generation of IMS DBAs. Uses the current web technologies. Access from anywhere via the Internet using popular web browsers. Includes a help system that serves as a learning aid for new IMS

DBAs.

for System z


• Visualize and change IMS database (DBDs) and program definition sources (PSBs)

– View IMS database hierarchical structures

– View, create, and edit PSBs

– Change/add fields in DBDs

– Import COBOL copybooks and PL/I structures to a database segment

– Generate DBD source and PSB source

• Access IMS data using SQL statements

– Leverage IMS V11 Universal JDBC driver

• Connect to the z/OS system

– Browse data sets

– Submit JCL and inspect the output in JES

– Import and export DBD and PSB source files from a data set to the IMS Explorer, and vice-versa

19

Double click under Imported Source to see the actual DBD source

Double click on the DBD name under the Imported Source to see the DBD source to generate the DBD to IMS



20

Double click under Generated Source to see the GUI representation of the DBD

Double click on the DBD name under the Generated Source to see the GUI representation of the DBD



21

Explorer knows there are some, but any DBDs of them is not imported here

Click on the Database Relationships button to see indexed of logical databases connected to this DBD

Now we want to see if there are any relationships to another DBD. We click on the DBD Relationship button to show those relationships. IMS Explorer can identify that there is a relationship, and can not display it because the DBD with the external relationship to be displayed is not available.



22

Explorer has found related Databases that may also need to be imported to allow a full view of related databases

After initially selecting the DBD to be Imported IMS Explorer will identify any related DBD and recommend they be selected to be Imported also



23

Click on the Database Relationships button to see indexed of logical databases connected to this DBD

Now we can see rated databases and how they are related

After Imported the rest of the related DBDs from the IMS Source dataset, we can now click on the DBD relationship button and see the related Database and how it is related.
