### Setting up EMSRV for Solaris

On Solaris, filesystems automatically have large file support but limits for the user starting the EMSRV process must still be set using the `ulimit` command. To set the limits for the user starting the EMSRV process, specify the number of 512 byte blocks as arguments on the `-Hf` and `-Sf` options of the ulimit command. Use the following commands to enable repositories up to 16 GB in size:

    ulimit -Hf 33554432
    ulimit -Sf unlimited

With large file support, EMSRV for Solaris supports a maximum repository size of 16 GB on UFS volumes.

EMSRV for Solaris implements authentication using PAM. PAM must be correctly configured on a machine running EMSRV otherwise it will not even be possible to shutdown EMSRV using EMADMIN. The `/etc/pam.conf` file must detail the `emsrv` service. This release includes an example `pam.conf` file in /opt/IBMvast/6.0/samples/PAM.
