IMS-DLI native browse, view segments, and layouts
Browse PSBs and hierarchical IMS segments through native DL/I batch, apply COBOL layouts, and approve which segments you can reach.
Some IMS databases are not exposed through JDBC, or they need a PSB-scoped DL/I call. OL CoreIQ runs that call through the bundled OLIMDBR program. SQL-like access, when ODBM is available, is IMS-DB Universal JDBC.
