The PAL is a Platform Abstraction Layer that is used in a variety of projects. The PAL allows for easy compatibility between many different flavors of UNIX/Linux, including AIX 6.1 and later, HP/UX 11.31 and later, Solaris 5.10 and later, and most versions of Linux as far back as RedHat 5.0, SuSE 10.1, and Debian 5.0.
The PAL has two primary components:
SCXCoreLib provides portable services for:
- atomic handling
- UNIX conditions
- directory lookup
- file handling (reading/writing/modifying)
- ref-counted handle mechanism to release on last use
- common logging framework
- marshalling/unmarshalling
- DNS name resolution
- pocess launching/controlling
- regular expressions
- singletons
- threading
- time handling
- other various functions
The above list is not intended to be all-inclusive. Features are added to the PAL as necessary.
SCXSystemLib primarily returns statistical information for products like SCXcore and SCXcm, and other omi providers. This subsystem primarily follows the CIM module (enumerate a set of instances, get detailed information on a specific instance).
Primary enumeration information is supported for:
- bios
- computer system
- cpu statistics
- cpu property information
- disk information
- file system information
- installed software
- memory information
- network configuration
- network routing information
- operating system information
- process information
- processor information
This component tends to be highly system specific, and may run on fewer systems than SCXCoreLib, above.
