13.3 Distributing the Database Directory and the Spool Directory The following describes how to distribute the database directory and the spool directory to optional disks for such cases as executing a large numbers of jobs in a subsystem environment.
Directory storage location
When a subsystem environment is created, the database directory and the spool directory are stored in the following locations.
Database directory
Windows | Installation directory\MpWalker.JM\mpjobsch\jobdbn |
Solaris | /var/opt/FJSVJOBSC/JOBDBn |
HP-UX | /opt/FHPJOBSCH/db/JOBDBn |
AIX | /usr/FAIXJOBSC/db/JOBDBn |
Linux | /var/opt/FJSVJOBSC/JOBDBn |
Spool directory
Windows | Installation directory\MpWalker.JM\mpmjessv\mjesn\mjespool |
Solaris | /var/opt/FJSVMJS/var/spool/mjes/mjesn |
HP-UX | /opt/FHPMJS/var/spool/mjes/mjesn |
AIX | /opt/FAIXMJS/var/spool/mjes/mjesn |
Linux | /var/opt/FJSVMJS/var/spool/mjes/mjesn |
"n" in "JOBDBn", "jobdbn" and "mjesn" above corresponds to the subsystem number from one to nine. When the subsystem number is zero, the same directory as when not using multiple subsystems will be used.
Procedure to distribute directories [UNIX version]
Distribution of database directory and spool directory in the UNIX system environment can be carried out by moving the database and spool directories to optional disks and creating symbolic links in the default storage location when the subsystem environment has been created.
The following provides an example of moving the database directory to "/disk1" and the spool directory to "/disk2" in the Solaris environment.
1) Moving to disks
Move the database directory and the spool directory to different disks.
# mv /var/opt/FJSVJOBSC/JOBDBn /disk1/JOBDBn |
2) Creating symbolic links
Create symbolic links as follows.
# ln -s /disk1/JOBDBn /var/opt/FJSVJOBSC/JOBDBn |
Remark: Replace "n" in the example above with the actual subsystem number.
Procedure to distribute directories [Windows version]
Distribution of database directory and spool directory in the Windows system environment can be carried out by specifying the database directory and the spool directory on the distribution destination disks in the sheet displayed from the Systemwalker Operation Manager Environment Setup window.
Display the Database sheet of the Define Jobscheduler Startup Parameters window from the Systemwalker Operation Manager Environment Setup window. In this window, change the default drive name to a drive name on another disk.
Display the Define Operating Information window from the Systemwalker Operation Manager Environment Setup window. In the Spool directory field in the Cluster settings sheet of the Define Operating Information window, change the directory to a directory on another disk.
Note
If you specify the spool directory, its files and directories are deleted when you start up the system in the Initialization mode. This is because the spool directory is used as the work directory by Job Execution Control. Always specify an empty directory as the destination of spool directory.
