VisualAge Smalltalk Server provides a mechanism by which application programmers can run packaged application images without rebuilding the load module. These application images are stored in data sets (RECFM=FB, LRECL=80) that are dynamically allocated at run-time. Before the application programmer can use this feature, the image data sets must be defined in the image control table (ICT).
To setup the ICT, do the following:
Note: | The data set name is of your choice: This document uses
HLQW.ABT450. The ICT requires the following four
statements:
|
ICT TITLE 'VA SMALLTALK SERVER IMAGE CONTROL TABLE' ABTICT TYPE=INITIAL ABTICT TYPE=ENTRY, DSN=HLQ.SMALTALK.IMAGE ABTCIT TYPE=FINAL END
Note that the table is searched in the order in which the entries are placed. Also the dataset does not need to exist at the time the table is created.
Note: | IMS, CICS, and MVS Native can share the same image data sets through the same ICT, or you can generate separate ICTs for IMS, CICS, and MVS Native. Also, test and production systems in IMS, CICS and MVS Native can share the ICT. |
