File Manager - IMS component
The IMS component of File Manager (FM/IMS) is an ISPF application, in which you can manipulate data stored in IMS databases. Using FM/IMS, you can:
Display data from one or more IMS segment occurrences, and see their relationship to other segment types within the database.
Edit and update data in IMS segment occurrences.
Insert segment occurrences into a IMS database.
Delete segment occurrences from an IMS database.
Extract a subset of IMS data to a flat file.
Load data into IMS databases.
Print selected data or entire databases.
For many tasks, you can use the FM/IMS elements called templates and views to define a logical view of a database, based upon field definitions from COBOL or PL/I copybooks. When you associate a view with a database you can:
Format data according to segment layouts defined in COBOL or PL/1 copybooks.
Select the segment types and fields that you want to display, edit or extract.
Change the order in which fields are displayed and adjust field headings.
Create criteria to identify and select the data that you want to use.
FM/IMS provides you with a number of flexible ways to connect to your IMS databases. For example, with BMP mode you can connect to an online multi-user database and manipulate the data. In DLI mode, you can work with data offline as a single user or you can share the data with others.
In addition, FM/IMS provides two functions that you can use in batch jobs. FM/IMS Edit Batch (IEB) runs a REXX procedure that can insert, update, retrieve, delete or print segments and create views. FM/IMS Batch Print (IPR) can print the entire database in one of several available display formats, or a selected subset of the database, based on a view.
The File Manager for IMS component of V8.1 has the following enhancements:
File Manager IMS is enhanced to support IMS V10.
File Manager IMS is enhanced to allow customization of a group of IMS settings for use in File Manager DL/I mode operations. This is similar to the capability that already exists for File Manager IMS settings that you can custom for batch message processing (BMP) mode access. A group of File Manager IMS DL/I options settings, once established, can be used by simply referring to an IMS "subsystem ID" name, instead of filling out many options panels. These File Manager DL/I mode options can also be customized as over-rideable by the user, or not.
