How do I enable 16MB pages for an account that uses LDAP?

[DavidYeager]

With an account that uses "Login AUTHENTICATION GRAMMAR" = "LDAP", I get this when trying to enable 16 MB page support:

-bash-3.00# chuser capabilities=CAP_BYPASS_RAC_VMM,CAP_PROPAGATE trbld
Error changing "capabilities" to "CAP_BYPASS_RAC_VMM,CAP_PROPAGATE" : Value is invalid.

However, it works when the account uses "compat" as its login authentication grammer.

I really need to get this to work for an LDAP account. Any suggestions?

-R flag on the chuser command?

chuser -R LDAP ...

or whatever load module you need in order to connect to LDAP server and change the user on the server.


HTH,

Thanks for the help, but unfortunately it still doesn't work.

-bash-3.00# chuser -R LDAP capabilities=CAP_BYPASS_RAC_VMM,CAP_PROPAGATE trbld
Error changing "capabilities" to "CAP_BYPASS_RAC_VMM,CAP_PROPAGATE" : Value is invalid.

Have you set your system to use large pages?

I believe the default is to not have any memory allocated to the large page physical memory pool.

Also you may have a typo

Try

CAP_BYPASS.RAC_VMM,CAP_PROPAGATE

Thanks for the response. I'm sure I have configured the system to use large pages because I tested this while running jobs as root. The problem is when trying to add this capability to users that use LDAP as their authentication grammar. I have also tried the CAP_BYPASS_RAC_VMM => CAP_BYPASS.RAC_VMM spelling, and that didn't work. I believe the first spelling is correct since that is how it is spelled under the man entry for my version of chuser, and this command has worked before for accounts with he compat authentication grammar. I noticed the second spelling in google searches and I'm guessing it's for an older version.
