1.10.4 Database Definition - imsdbs.desc
imsdbs.desc is located
under$ART_IMS_CONFIG.
Some imsdbs.desc field configurations are mapped
from some DBD statement of IMS on z/OS. For persistent transactions
that issue ROLB or ROLL, the retry count
for creating the transaction queue should be set to a relatively
large number (the largest number could up to 2147483647).
Note:
It is suggested that the retry count is set to a number that is more than twice the number that a particular message enters a persistent transaction.Table 1-28 Section Name: [imsdb]

Input File Name. If this name is defined in JCL with the same

associated with the DD name in JCL. Otherwise, the real input file
is $ART_IMS_DB/Input file name.
