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
