Steps to create a Syctl application

Task :- User siju (kerberos principal siju.adm) should get the permission to start a subsystem by executingthe command substart. Permission should not be given to other users.

1) Create the client application substart in /usr/bin directory of cws with following contents

if [ $# -gt 2 ]then echo "Arguments exceed the limit"exit 1

fi/usr/lpp/ssp/bin/hostlist -n $1 | /usr/bin/sysctl -c - substart_proc $2

In the above script if condition will check for the number of arguments and execute procedure oncorresponding host

2) Change the mode to executable

chmod 755 /usr/bin/substart

3) Create server application substart.tcl with a procedure substart_proc with following contents

create proc substart_proc {SubSystem} AUTH {global SCUSERif [ aclcheck -f /etc/substart.acl $SCUSER ] {

exec /etc/substart.srv $SubSystemreturn}

}

if condition in the above example checks for kerberos user in the acl file /etc/substart.aclIf the condition is true it execute the command /etc/substart.srv with arguments passed bysubstart command

4) Create the script substart.srv with following contents

startsrc -s $2

This script execute the command startsrc with the argument passed by the substart command

5) Change the mode to executable

chmod 755 /etc/substart.srv

6) Create acl file substart.acl with the entry for user siju

#acl#


20/25

_PRINCIPAL siju.adm@CWS

7) Add the application to the sysctl by adding following line to sysctl.conf file

include /etc/substart.tcl

8) Distribute the files to all nodes

pcp -av /usr/bin/substartpcp -av /etc/substart.tclpcp -av /etc/substart.srvpcp -av /etc/substart.aclpcp -av /etc/sysctl.conf

9) Restart the sysctld daemon to get the new information on cws and on all nodes

10) Get the kerberos ticket for user siju and execute following command

substart 3 lpd

This should start the lpd daemon on node 3

11) Try the above command with any other kerberos ticket. Result should be negative

Cluster stateCheck the status of the cluster daemons by issuing lssrc -g cluster and lssrc -g lock.

Run /usr/sbin/cluster/clstat to check the status of the cluster and the status of the network interfaces.Check the cluster log files with tail -f /tmp/hacmp.out, more/usr/sbin/cluster/history/cluster.mmdd (mmdd = current date), tail -f/var/adm/cluster.log, and more /tmp/cm.log.

Check that the nodename is correct (use odmget HACMPcluster).

Verify that all the HACMP Configuration is synchronized. To check the state of the HACMP clusternodes, you have to test the topology and configuration of your HACMP cluster. This is done by using theclverify command.

The state of cluster can be found by using the /usr/sbin/cluster/clstat

LPARuname L

Use the uname command to obtain information about the system in relation to the LPAR.

> uname -L-1 NULLThe "-1" indicates that the system is not running with any logical partitions, but is running in full systempartition mode.


24/25

The following example demonstrates how the uname command provides the partition number and thepartition name as managed by the HMC:

> uname -L3 Web ServerKnowing that the application is running in an LPAR can be helpful when you are assessing slightperformance differences.
