The Main Storage Allocator Record controls the loading of the application fixed main storage area (GLOBAL). Since the ART resides protected main storage area a set of load control entries must be included in the GOA record for GLOBAL Area 1. For each ART record three parameters must be provided to describe the file location of the main storage backup, the size and characteristics of the main storage resident area. Each of these parameters is described below:
Other indicators in this item will show that it is:
Figure 5 in Examples shows an ART record requiring 4 items defined in the GOA to load an ART main storage table of 4144 bytes. The next available index in GL0BA is 49 (first nonkeypointable index) and the next available ordinal numbers in #GLOBL are 48 thru 51.
The user should also be aware that an increase in main storage usage in the global area may necessitate an increase in the amount of main storage allocated to that area. This value is set in Keypoint Record A via SIP macro GLOBAL. Also the size of the GL0BA directory is defined in the GLOBZ macro. Care should be made that the directory size (in doublewords) has sufficient space for an additional index item.
Name Number of Bytes Description @ARTCR 4 main storage address of ART @ARTFA 4 File address of ART
The above values are set by GOGO (INSLLBL) at restart.
The Application Recovery Table (ART) is a main storage table with file taken from record type #GLOBL. This may require SIP input modification to the FCTB (Face Table, FC0TB) to increase the number of records allocated to #GLOBL.
