Installation Requirements

The JAMS installation takes 10–20 minutes. Please note: before installing JAMS, you must have the following privileges and resources:

SETPRV privileges, or CMKRNL, WORLD, and SYSPRV privileges

At least 13,000 (17,000 for Alpha) free blocks of disk space on the device that will hold the JAMS Executable files

At least 7,000 free blocks of disk space on the device that will hold the JAMS data files

A minimum of 2,200 (3,100 for Alpha) free global pages

A minimum of 15 free global sections

The installation procedure initially checks for the required resources before it begins the installation. However, if any resources are deficient, the procedure will issue error messages and identify the resource(s) before terminating the installation.

To determine the number of free global pages on your system, type the following DCL command:

$ WRITE SYS$OUTPUT F$GETSYI("FREE_GBLPAGES")

The number displayed equals the total number of free global pages. If this number is less than 1,800 (3,600 for Alpha), increase the GBLPAGES system parameter by editing the file SYS$SYSTEM:MODPARAMS.DAT and invoking the SYS$UPDATE:AUTOGEN.COM command procedure.

For more information on adjusting SYSGEN parameters and using AUTOGEN, please refer to the appropriate VMS documentation.

Installation Procedure

To install the JAMS Scheduler on OpenVMS, follow the 9 steps below:

Invoke VMSINSTAL $ @VMSINSTAL JAMSAXP040 DKA400:[JAMS040.KIT]

Answer the standard VMSINSTAL questions. VMSINSTAL will ask if you are satisfied with the backup of your system disk. Also, it may ask additional questions if you are not logged on as SYSTEM or it detects other unusual conditions.

Provide the device name for the JAMS executables. You will be asked what disk device to use for the JAMS executables.

Note: You can install both VAX and AXPexecutables on the same device. JAMS will create different directories for each installation.

Provide device name for JAMS data. You will then be requested to select what disk device to use for the JAMS data files.

Note: You can store the data files on the same disk as the executables. However, the JAMS data disk must be the same on all nodes in VMScluster.

Note: To abort the installation procedure at any time, press CTRL/Y. The installation procedure cleans up any files it has created and returns to the DCL prompt.

Start JAMS once the installation is complete? To execute the JAMS startup procedure when the installation is complete, press Return; otherwise enter NO and press Return.

Purge Files?

You will be asked if you want to purge files replaced by this installation. To purge, press Return; otherwise, enter NO and press Return.

Run the IVP?

If you want to run the JAMS installation verification procedure (IVP) after completing the installation, press Return; otherwise, enter NO and press Return.

Read the informational messages.

As the installation proceeds, you should scan the on screen informational messages for potential problems.

JAMS puts all files in its own directory tree, with the exception of the following files: SYS$STARTUP:JAMS_STARTUP.COM

VUE$LIBRARY:JAMS_PROFILE.VUE$DAT

VUE$LIBRARY:JAMS_VUE_STARTUP.COM
