To let you control operating system and third-party processes,
Privileged Access Manager Server Control
lets you make calls to UNIX exits automatically when unloading the kernel extension.When you run
SEOS_load -u
, Privileged Access Manager Server Control
performs the following actions:- Looks for programs in the following directory:ACInstallDir/exits/LOAD
- Selects all the programs that have file names of the following format:SEOS_unload_string.alwaysWherestringcan be any descriptive strings.
- Executes, in lexicographical order, each file it found in the directoryACInstallDir/exits/LOAD:SEOS_load_string.always -preEach file is executed with the-preparameter so that you can write your exits to detect the parameter and perform the actions required before the kernel is unloaded.If the exit returns a nonzero value,Privileged Access Manager Server Controlkills the exit process, displays an error message, and aborts the kernel unloading.
- Tries to unload the kernel.If the kerneldoes notunload:
- Selects all the programs that have file names of the following format:
SEOS_unload_string.opt Executes, in lexicographical order, each file it found in the directory ACInstallDir/exits/LOAD: SEOS_unload_string.opt -preEach file is executed with the -pre parameter so that you can write your conditional exits to detect the parameter and perform the additional optional actions required before the kernel is unloaded.Note: If the exit returns a nonzero value, CA ControlMinder kills the exit process, displays an error message, and aborts the kernel unloading.Unloads the kernel.Executes, in lexicographical order, each file it found in the directory ACInstallDir/exits/LOAD: SEOS_unload_string.opt -postEach file is executed with the -post parameter so that you can write your conditional exits to detect the parameter and perform the additional optional actions required before the kernel is unloaded.Note: If the exit returns a nonzero value, CA ControlMinder kills the exit process and displays an error message. Having already been unloaded, the CA ControlMinder kernel remains unloaded.SEOS_unload_string.opt- Executes, in lexicographical order, each file it found in the directoryACInstallDir/exits/LOAD:
