Offline analysis
Fast Path Analyzer/EP can read and analyze an offline DEDB.
Offline analysis operating characteristics are as follows:
- The DEDB is offline to IMS when analysis occurs.
- Read-with-integrity access is used.
- No other application can update the DEDB while analysis is in progress.
To analyze an offline DEDB, the ACCESS keyword is set to OFFLINE (the default value). During analysis, no other applications can update the database.
Inputs and outputs
The following figure shows the inputs and outputs for the offline analysis function.
Control statement
A sample control statement for an offline analysis is shown in the following figure. In this example, the area data set and ACB library are accessed by using dynamic allocation. Analysis will be limited only to the area that is specified with the IAREA keyword.
//STEPLIB DD DSN=BMC.PFP.LOAD,DISP=SHR
// DD DSN=IMS.RESLIB,DISP=SHR
//PFPSYSIN DD *

DBRC considerations
When DBRC is active during execution of the offline analysis function, and the area is registered, a read-with-integrity authorization level is requested for the area data set.
If the area data set is used as input, the data set name must match the name that is registered with DBRC.
MADS considerations
When DBRC is active during execution of the offline analysis function, and the area is registered, a read-with-integrity authorization level is requested for the area data set.
If the area data set is used as input, the data set name must match the name that is registered with DBRC.
