Issues starting Siebel Server on Unix

Scenario: UNIX file system reaches 100% and none of the Siebel services are getting started and starting them results in protection error.

Solution: Clean up the file system by deleting some old logs and core dumps found under SIEBEL_ROOT/log and SIEBEL_ROOT/bin respectively.
Rename the osdf.(gateway name).(enterprise name) file under SIEBEL_ROOT/sys directory.
Rename the (gateway name).(enterprise name).shm file under SIEBEL_ROOT/admin directory.
Start the gateway server followed by the enterprise server; the servers will come up clean with all the protections removed.
