28.3 Edit/browse without using a view
Next we discuss editing and browsing without using a view.
28.3.1 Preparation
From the Primary Option Menu shown in Figure 28-9 we select option 1 (Browse data) and
press Enter.
Figure 28-9 Primary Options Menu
FM/IMS will now show the Browse Entry Panel (Figure 28-10 on page 845). In this panel we
can see that a dynamic PSB will be used. We defined this in a previous step.
On this panel we specify:
򐂰 For the DBD
Data set name 1: the DBD library (or libraries) that the database definitions are to be
obtained from (in this example, CHABERT.IMS.TRADER.DBDLIB).
Member: the name of the database (in this example, DR1E). If we leave the field blank
or enter a pattern, a member selection list is displayed. We can select a member from
this list.
򐂰 Processing options
When accessing the database we can do that in two modes:
DL/I mode
When the database is offline, we access it in DLI mode. In DLI mode, we must specify
the data sets that we want to update, and security is controlled at the data set level
(that is, if we have access to the data sets via ISPF, we can access them via FM/IMS in
DLI mode). These data sets are allocated to the TSO address space and we manually
control the environment by using the Set Options panels. This type of access is
typically used by developers. While DLI mode usually provides single user access, we
Chapter 28. File Manager/IMS 845
can share databases with other users by working with the IRLM option turned on
(depending on your IMS subsystems definitions).
–BMP mode
When the database is allocated to an online system, we access it in BMP mode. BMP
mode provides strict controls that are suited to live production environments. For
example, we can only access those database data sets that have been defined for the
IMS subsystem. Any changes that we make are logged in the IMS online log data set
and IMS controls such things as multi-user access to the segment data and automatic
backout if needed.

After completing the information in the Browse Entry Panel we press Enter and the Database
Data Set Specification panel (as shown in Figure 28-11) will be shown. Here we enter the
data set names for the DBD. We can also enter a slash (/) to choose to save these names in
our profile to be reused next time we access this DBD.
