6.5.3 Logical host operation in the non-cluster system

(a) In a Windows environment

To set automatic startup and automatic termination:

1. Use a text editor to add the following code in the start sequence definition file (JP1SVPRM.DAT):

   storage-destination: Base-path\conf\boot\JP1SVPRM.DAT

   [Jp1BaseEvent_logical-host-name]

   Name=JP1/BaseEvent_logical-host-name

   ServiceName=JP1_Base_Event logical-host-name

   [Jp1Base_logical-host-name]

   Name=JP1/Base_logical-host-name

   ServiceName=JP1_Base_logical-host-name

   StopCommand=jbs_spmd_stop.exe -h logical-host-name

   [JP1/IM-Manager DB Cluster Service_logical-host-name]

   Name=JP1/IM-Manager DB Cluster Service_logical-host-name

   ServiceName=HiRDBClusterService_JMn

   StopCommand=Manager-path\bin\imdb\jimdbstop.exe -h logical-host-name

   [Jp1IM-Manager_logical-host-name]

   Name=JP1/IM-Manager_logical-host-name

   ServiceName=JP1_Console_logical-host-name

   StopCommand=jco_spmd_stop.exe -h logical-host-name

   JMn: For n, specify the same value as specified for LOGICALHOSTNUMBER in the cluster setup information file.

   The command specified in the StopCommand parameter is executed when shutdown is performed from JP1/Power Monitor.

(b) In a Solaris environment

To set automatic startup and automatic termination:

1. Create an automatic startup script and an automatic termination script for the logical host.

   storage-destination:/etc/init.d/jp1_service_cluster

   Example of automatic startup and automatic termination scripts:

   #!/bin/sh

   ## Set Environment-variables

   PATH=/sbin:/bin:/usr/bin:/opt/jp1base/bin:/opt/jp1cons/bin

   export PATH

   JP1_HOSTNAME=logical-host-name

   export JP1_HOSTNAME

   case $1 in

   start_msg)

   echo "Start JP1 Service $JP1_HOSTNAME"

   ;;

   stop_msg)

   echo "Stop JP1 Service $JP1_HOSTNAME"

   ;;

   'start')

   if [ -x /etc/opt/jp1base/jbs_start.cluster ]

   then

   /etc/opt/jp1base/jbs_start.cluster

   fi

   if [ -x /etc/opt/jp1cons/jco_start.cluster ]

   then

   /etc/opt/jp1cons/jco_start.cluster

   fi

   ;;

   'stop')

   if [ -x /etc/opt/jp1cons/jco_stop.cluster ]

   then

   /etc/opt/jp1cons/jco_stop.cluster

   fi

   if [ -x /etc/opt/jp1base/jbs_stop.cluster ]

   then

   /etc/opt/jp1base/jbs_stop.cluster

   fi

   ;;

   esac

   exit 0

2. Set a link to the scripts created in step 1.

   Startup script

   Execute the following command to set the link:

   ln -s /etc/init.d/jp1_service_cluster /etc/rc2.d/S**_JP1_SERVICE

   The larger the value of ** in a start script, the later the script is executed.

   Termination script

   Execute the following command to set the link:

   ln -s /etc/init.d/jp1_service_cluster /etc/rc0.d/K**_JP1_SERVICE

   The larger the value of ** in a termination script, the later the script is executed.

   In general, set the program that is started first to be stopped last.

(c) In an AIX environment

To set automatic startup and automatic termination:

1. Use the mkitab command to add the following code in the /etc/inittab file:

   # mkitab -i hntr2mon "jp1base:2:wait:/etc/opt/jp1base/jbs_start.cluster logical-host-name"

   # mkitab -i jp1base "jp1cons:2:wait:/etc/opt/jp1cons/jco_start.cluster logical-host-name"

   This code executes JP1 service startup processing when the system starts.

2. Following the entries for products that require JP1/Base and JP1/IM - Manager in /etc/rc.shutdown, use a text editor to add the following code:

   test -x /etc/opt/jp1cons/jco_stop.cluster && /etc/opt/jp1cons/jco_stop.cluster logical-host-name

   test -x /etc/opt/jp1base/jbs_stop.cluster && /etc/opt/jp1base/jbs_stop.cluster logical-host-name

   test -x /opt/hitachi/HNTRLib2/etc/D002stop &&

   /opt/hitachi/HNTRLib2/etc/D002stop

   This code executes JP1 service stop processing when the system terminates.

(d) In a Linux environment

To set automatic startup and automatic termination:

1. Create an automatic startup script and an automatic termination script for the logical host.

   Storage location: /etc/rc.d/init.d/jp1_service_cluster

   Example of automatic startup and automatic termination scripts:

   #!/bin/sh

   ## Set Environment-variables

   PATH=/sbin:/bin:/usr/bin:/opt/jp1base/bin:/opt/jp1cons/bin

   export PATH

   JP1_HOSTNAME=logical-host-name

   export JP1_HOSTNAME

   case $1 in

   start_msg)

   echo "Start JP1 Service $JP1_HOSTNAME"

   ;;

   stop_msg)

   echo "Stop JP1 Service $JP1_HOSTNAME"

   ;;

   'start')

   if [ -x /etc/opt/jp1base/jbs_start.cluster ]

   then

   /etc/opt/jp1base/jbs_start.cluster

   touch /var/lock/subsys/_JP1_BASE_$JP1_HOSTNAME

   set_return

   fi

   if [ -x /etc/opt/jp1cons/jco_start.cluster ]

   then

   /etc/opt/jp1cons/jco_start.cluster

   touch /var/lock/subsys/_JP1_CONS_$JP1_HOSTNAME

   set_return

   fi

   ;;

   'stop')

   if [ -x /etc/opt/jp1cons/jco_stop.cluster ]

   then

   /etc/opt/jp1cons/jco_stop.cluster

   rm -f /var/lock/subsys/_JP1_CONS_$JP1_HOSTNAME

   fi

   if [ -x /etc/opt/jp1base/jbs_stop.cluster ]

   then

   /etc/opt/jp1base/jbs_stop.cluster

   rm -f /var/lock/subsys/_JP1_BASE_$JP1_HOSTNAME

   fi

   ;;

   esac

   exit 0

2. Set a link to the scripts created in step 1.

   Startup script

   Execute the following command to set the link:

   ln -s /etc/rc.d/init.d/jp1_service_cluster /etc/rc.d/rc3.d/S**_JP1_SERVICE

   ln -s /etc/rc.d/init.d/jp1_service_cluster /etc/rc.d/rc5.d/S**_JP1_SERVICE

   The larger the value of ** in a startup script, the later the execution of the script.

   Termination script

   Execute the following command to set the link:

   ln -s /etc/rc.d/init.d/jp1_service_cluster /etc/rc.d/rc0.d/K**_JP1_SERVICE

   ln -s /etc/rc.d/init.d/jp1_service_cluster /etc/rc.d/rc6.d/K**_JP1_SERVICE

   The larger the value of ** in a termination script, the later the execution of the script.

   In general, set the program started first as the last program to be stopped.

   If you want to automatically terminate JP1 services, make sure that you automatically start them. If you set up only automatic startup, the termination script will not start.

(e) Settings for performing automatic startup and automatic termination on both physical and logical hosts

To perform automatic startup and automatic termination on both physical and logical hosts, you must specify the settings described below in addition to the automatic startup and termination settings for the logical host.

The setting method depends on the OS. This subsection describes the setting method for each OS.

In a Windows environment:

Startup control executes startup and termination processing sequentially in the order specified in the start sequence definition file (JP1SVPRM.DAT). To change the startup sequence of physical and logical hosts, define the startup and termination of physical and logical hosts in the desired sequence in the startup sequence definition file (JP1SVPRM.DAT).

In a Solaris or Linux environment:

The sequence of automatic startup and automatic termination is determined by the value of ** in the expressions S** and K** in the automatic startup and termination scripts. The greater the value of **, the later the processing is executed. A symbolic link to the automatic startup and termination scripts for the physical host is created automatically during installation. To also perform automatic startup and termination for the physical host, rename the symbolic link that is created for the logical host, and then adjust the startup and termination sequence for both physical and logical hosts.

Automatic startup and automatic termination scripts for a physical host have already been provided. The following table provides a list of the symbolic links to the automatic startup and automatic termination scripts for a physical host.

Table 6‒15: List of symbolic links to automatic startup and automatic termination scripts for a physical host

OS name	Startup script	Termination script
Solaris	/etc/rc2.d/S99_JP1_20_CONS	/etc/rc0.d/K01_JP1_80_CONS
Linux	/etc/rc.d/rc3.d/S99_JP1_20_CONS	/etc/rc.d/rc0.d/K01_JP1_80_CONS
	/etc/rc.d/rc5.d/S99_JP1_20_CONS	/etc/rc.d/rc6.d/K01_JP1_80_CONS

Adjust the startup sequence for the physical and logical hosts according to the relationship between the value (numeric) of ** in the expressions S** and K** in the above list, and the value (numeric) of ** in the expressions S** and K** in the symbolic link in the automatic startup and termination scripts for the logical host.

For example, to start the logical host first, set a value that is less than 99 (for Solaris and Linux) in ** in the expression S** that is the name of the symbolic link to the automatic startup script for a logical host.

In an AIX environment:

To perform automatic startup and termination of a physical host, you must add settings. For details about these settings, see 2.18.2 Setting automatic startup and automatic stop.
