The UNIX operating environments currently supported by the UNIX agent in
CA Client Automation
 are listed in the Compatibility Matrix. The platforms listed there are also the platforms on which the Packager for Linux and UNIX can run.
Installation Prerequisites for the Agent on Sun Solaris
Before you install the UNIX agent on a Sun Solaris computer, you must ensure that the required minimum kernel configuration parameters are set.
To set or modify the kernel configuration parameters for Solaris 5.10
For Solaris 5.10, the resource control configuration parameter max-shm-memory must be set to 5242880
or higher and the max-sem-ids parameter must be set to 256 or higher.
  1. Query the current values of these parameters using the prctl command, for example:
    prctl - P - n project.max-shm-memory - i project user.root prctl - P - n project.max-sem-ids - i project user.root
  2. If the resource control configuration parameters need to be updated, use
    one
    of the following commands:
    • Use prctl to modify resource control configuration parameters, for example:
      prctl -n project.max-shm-memory -v 5242880 -r -i project user.root prctl -n project.max-sem-ids -v 256 -r -i project user.root
      Configuration parameters modified using the prctl command are
      not
      persistent and you need to run the commands again after the system is restarted.
    • Use projmod to modify resource control configuration parameters, for example:
      projmod -s -K "project.max-shm-memory=(priv,5242880,deny)" user.root projmod -s -K "project.max-sem-ids=(priv,256,deny)" user.root
      Configuration parameters modified using the projmod command are persistent after the system is restarted.
Installation Prerequisites for the Agent on IBM AIX
The latest Runtime Environment libraries from IBM are installed when you install the
CA Client Automation
 UNIX agent on an IBM AIX computer running AIX version 5.3 and later.
Software Delivery Download and UNIX Agents
The following consideration applies when the software delivery download method is set to the Internal NOS method.
The Sun Solaris kernel currently does not support mounting Samba shares.
If the Scalability Server has only NFS mount points configured (that is, it does not use Samba), the Sun Solaris agents will automatically use NFS.
If the Scalability Server has Samba shares configured, and the NOSLessSwitchAllowed parameter is 1 (True), the Sun Solaris agents will fall back to use the Internal NOSless download method.
If the Scalability Server has Samba shares configured, and the NOSLessSwitchAllowed parameter is 0 (False), the download will fail, even if the Scalability Server also has NFS mount points configured.
The current value of the NOSLessSwitchAllowed parameter can be verified by running the command:
ccnfcmda -cmd GetParameterValue -ps itrm/usd/agent -pn NOSLessSwitchAllowed
The value of the NOSLessSwitchAllowed parameter can be set to 1 by running the command:
ccnfcmda -cmd SetParameterValue -ps itrm/usd/agent -pn NOSLessSwitchAllowed -v 1
