nhCheckInstallPreReqs fails on kernel.sem

Products

• CA eHealth

Issue/Introduction

Issue/Problem/Symptoms: 

nhCheckInstallPreReqs fail with the below which in turn causes attempts at running Install to fail as well:

     ./nhCheckInstallPreReqs -noPass

     NOTE -- Installing eHealth on Red Hat Enterprise Linux r7.2.

     Parameter sem needs to be at least 250 32000 100 128 but is  250        32000   100     128

     -1

Environment:  

eHealth 6.3.2.11 & 6.3.2.12

Linux 7.x (most seen in 7.2)

Cause: 

kernel.sem_next_id also exists in addition to kernel.sem

Resolution:

This problem is slated to be resolved in 6.3.2.13. 

Workaround:

Validate that kernel.sem is set to at least 250 3200 100 128 by running:

     sysctl -a | grep "kernel.sem ="

 

Example output would be:

     kernel.sem = 250        32000   100     128

 

So long as this is the ONLY failure of the nhCheckInstallPreReqs script, you can then initiate the install by issuing the below command:

     ./Install –noCheck

Additional Information: 

By using the –noCheck switch in any other situation when not directed by CA Support may potentially corrupt your installation / upgrade.  Use this switch ONLY at the direction of CA Support.  If you have any questions or concerns please open up a support case at http://support.ca.com and reference this KB Article in the description.
