Access Method
Access Method shows the access method used to process the data set:
Method | Description |
|---|---|
BATCHPIPE | files processed by the BatchPipes subsystem |
BDAM | basic direct access method |
BDAM FP | basic direct access method fast path |
BPAM | basic partitioned access method |
BSAM | basic sequential access method |
EXCP | direct invocation of execute channel program |
HFS | Hierarchical File System |
IAM | accessing an BMC AMI Storage IAM (IAM) file |
IAMLOAD | loading an IAM file |
ISAM | indexed sequential access method |
MEDIA MGR | Media Manager |
MM/EXTSEQ | Media Manager on behalf of extended sequential format data sets |
MM/PDSE | Media Manager on behalf of partitioned data set extended |
OSAM | overflow sequential access method |
Other | non-standard access method |
QSAM | queued sequential access method |
TCAM LINE | telecommunications access method line group |
TCAM MSG | telecommunications access method message queue |
VIO | virtual input/output |
VSAM | virtual storage access method |
ZFS | zSeries File System |
For VSAM this field may contain:
Abbreviation | Meaning |
|---|---|
VSAM AIXD | data portion of an alternate index |
VSAM AIXX | index portion of an alternate index |
VSAM ESDS | entry sequenced data set |
VSAM KSDS | key sequenced data set |
VSAM INDX | index of a key sequenced data set |
VSAM LDS | linear data set |
VSAM RRDS | relative record data set |
VSAM UPGD | data portion of an alternate index in the upgrade mode |
VSAM UPGX | index of an alternate index in the upgrade mode |
VSAM VRRD | variable length relative record data set |
The VSAM values may be followed by:
FP | fast path |
GSR | global shared resource |
LSR | local shared resource |
If a file is processed without shared resources and as an LSR, the report will identify it as an LSR.
