Adabas Audit Data Retrieval uses spool files to store lists and indexes. Adabas Audit Data Retrieval uses spool files of the following type:
Adabas Audit Data Retrieval requires at least one spool file of each type. When needed, additional spool files can be allocated manually or automatically.
These are the four types of spool files used by Adabas Audit Data Retrieval:
The Adabas Audit Data Retrieval online spool comprises one or several files of this type.
The Adabas Audit Data Retrieval reload spool comprises one or several files of this type.
The Adabas Audit Data Retrieval index spool comprises one or several files of this type.
The Adabas Audit Data Retrieval global index spool comprises one or several files of this type.
The Adabas Audit Data Retrieval cache spool comprises one or several files of this type.
Spool file models enable Adabas Audit Data Retrieval to allocate spool files automatically as required.
Adabas Audit Data Retrieval allocates required spool files when it runs out of storage space in the existing spool files. Adabas Audit Data Retrieval allocates these spool files based on the model spool definitions created using option D.1.
A model spool file does not require any storage space while its status is MODEL.
Important
To prevent the system from running out of storage space, you must ensure that there are always spool file model definitions available for each type of spool file (see "Creating spool model definitions").
By default, Adabas Audit Data Retrieval uses the standard spool files (Type = SP) also for reloaded lists/reports. It is possible
to use separate spool datasets for reloaded lists and reports. If you are using separate spool datasets for reloading (B08_RELOAD_
We recommend that you use a small number of large spool files rather than a large number of small spool files. Using a small number of spool files reduces the time required by batch jobs to allocate the datasets and the amount of memory used by batch jobs.
The first four spool files are allocated by the B97DBFOR job.
The maximum number of spool files (cache, global, index, and spool) that can be opened by Adabas Audit Data Retrieval is 32000.
Important: The operating system may have a lower limit for the maximum number of open files. For more information, see the description of the task I/O table (TIOT) in the IBM publication MVS Initialization and Tuning Reference, chapter "ALLOCxx (allocation system defaults)".
The following panel shows the three types of spool files. The status of each spool file is displayed in column Sta:
