Storage Mapping Views
The mapping information that is captured is presented in Oracle’s dynamic performance views.
Table 6-4 provides brief descriptions of these views. For more detailed information, refer to your
Oracle documentation.
Table 6-4 Storage Mapping Views
DescriptionView
Contains a list of all the mapping libraries that have been dynamically loaded by
the external process.
V$MAP_LIBRARY
Contains a list of all the file mapping structures in the shared memory of the instance.
V$MAP_FILE
Contains a list of all the file extent mapping structures in the shared memory of the
instance.
V$MAP_FILE_EXTENT
Contains a list of all the element mapping structures in the SGA of the instance.
V$MAP_ELEMENT
Contains supplementary information for all element mapping structures.
V$MAP_EXT_ELEMENT
Contains a list of all subelement mapping structures in the shared memory of the
instance.
V$MAP_SUBELEMENT
Describes the component list associated with the element name.
V$MAP_COMP_LIST
Contains the hierarchical arrangement of storage containers for the file. This
information is displayed as a series of rows. Each row represents a level in the
hierarchy.
V$MAP_FILE_IO_STACK
Verifying Oracle File Mapping Setup
To verify that $ORACLE_HOME is set up for Oracle file mapping (ORAMAP)
1. Verify $ORACLE_HOME is ready for Oracle file mapping (ORAMAP):
# cd $ORACLE_HOME/rdbms/filemap/bin
# ls -l
-r-r-sr-xr-x 1 root system 14614 Apr 08 19:16 fmputlhp
-xr-x--- 1 root system 900616 Apr 08 19:16 fmputl
2. Confirm the following items and make the appropriate corrections:
• root owns fmputlhp and the setud bit is set.
• The permissions for fmputlhp are -r-sr-xr-x.
• The permissions for fmputl are -r-xr-x---.
3. If any of these items is not set as specified, make the appropriate corrections.
Enabling Oracle File Mapping
To enable Oracle file mapping with the Veritas Storage Mapping option
1. Ensure that the file filemap.ora exists and contains a valid entry for the Veritas mapping
library for Oracle storage mapping.
# cd $ORACLE_HOME/rdbms/filemap/etc
# cat filemap.ora
For 64-bit Oracle, the filemap.ora file should contain the following setting:
• For PA
lib=VERITAS:/opt/VRTSdbed/lib/libvxoramap_64.so
• For IA
