WebSphere MQ Software

Perform the following steps to check for WebSphere MQ software:

1. Determine where the WebSphere MQ queue manager runs.

   • Local system

     If the WebSphere MQ queue manager runs on the local systen, then the queue manager runs on the same system on which you intend to install the gateway product set.

   • Remote system

     If the WebSphere MQ queue manager runs on a remote system, then the queue manager runs on a different system, and not the system where you intend to install the gateway product set.

2. Verify that the WebSphere MQ software is already installed. If the WebSphere MQ server software in installed on a different system than the gateway, then the WebSphere MQ client software must be installed on the gateway system.

3. Identify the name of the WebSphere MQ queue manager.

4. Identify the WebSphere MQ client channel definition.

If the queue manager resides on a different system than the gateway, then the WebSphere MQ client software is used to access the remote queue manager. A channel definition is required for this configuration.

Setting Environment Variables

Before installing Oracle Procedural Gateway for WebSphere MQ on UNIX platforms, set the the following environment variables:

• ORACLE_HOME

• ORACLE_SID

• DISPLAY

• TMP

  
  

  Note: Verify that the values that you assign to the environment variables, which are listed in this section, are less than 42 characters long. Longer values might generate errors such as ÒWord too longÓ during installation.

  
  

oraInventory Directory

Oracle Universal Installer creates the oraInventory directory the first time it is run on your system. The oraInventory directory keeps an inventory of the products that Oracle Universal Installer installs on your system as well as other installation information. If you have previously installed Oracle products, then you might already have an oraInventory directory.

• When a UNIX group name is specified, it grants that group the permission to write to the oraInventory directory.  If another group attempts to run Oracle Universal Installer, then they must have permission to write to the oraInventory directory. If they do not have permission the installation fails.

• The user running Oracle Universal Installer must have permission to write to the oraInventory directory and all its files. This is required to run the installer.

• The location of oraInventory is defined in /etc/oratab/oraInst.loc for HP 9000 Series HP-UX and AIX-Based Systems.

• The location of oraInventory is defined in /var/opt/oraInst.loc for Sun Solaris.

• The latest log file is oraInventory_location/logs/installActions.log. Log file names of previous installation sessions are in the following format: installActionsdatetime.log.

• Do not delete or manually alter the oraInventory directory or its contents. Doing this can prevent Oracle Universal Installer from locating products that you have installed on your system.

Starting Oracle Universal Installer

Perform the following steps to launch Oracle Universal Installer, which installs Oracle Procedural Gateway for WebSphere MQ:

1. Stop all Oracle processes and services (for example, the Oracle database).

2. Mount the installation CD-ROM.

   The Oracle Product Installation CD-ROM is in RockRidge format. To begin installation, insert the CD.

   To manually mount or unmount the CD-ROM, you must have root privileges. Unmount the CD-ROM before removing it from the drive.

   To manually mount the CD-ROM, perform the following tasks:

   1. Insert the Oracle Procedural Gateway for WebSphere MQ CD-ROM into the CD-ROM drive.

   2. Log in as the root user.

   3. Create the CD-ROM mount point directory.

      prompt> mkdir mount_point
      
      

   4. Mount the CD-ROM drive on the mount point directory and exit the root account:

      prompt> mount options device_name mount_point
      prompt> exit
      
      

   The following examples show how to mount the CD-ROM manually on /cdrom:

   Platform	Command Example
   AIX-Based Systems	prompt> mkdir /cdrom prompt> mount -o ro -V cdrfs device_name /mnt/cdrom prompt> exit
   HP 9000 Series HP-UX	Note:  Add the following line to the /etc/pfs_fstab file: /dev/dsk/c5t2d0./cdrom pfs-rrip xlat=unix 0 0 where /dev/dsk/c5t2d0 is the CD-ROM device file and pfs-rripxlat=unix 0 0 indicates the CD-ROM is in Rockridge extention. prompt> nohup /usr/sbin/pfs_mountd & prompt> nohup /usr/sbin/pfsd & Note:  Insert the CD-ROM into the CD-ROM drive. prompt> /usr/sbin/pfs_mount /cdrom prompt> exit
   Sun Solaris	prompt> mkdir /cdrom prompt> mount -r -F hsfs device_name /cdrom prompt> exit

   
   
   
   

   Note: For AIX-Based System users only. Before installing the gateways from the CD-ROM, become root and run rootpre.sh. Log in as root and change directory to the CD-ROM mount point. prompt> su root prompt> cd mount_point Run rootpre.sh and exit root account. prompt> ./rootpre.sh prompt> exit

   
   

3. Run Oracle Universal Installer from the CD-ROM.

   
   

   Note: Be sure you are not logged in as the root user when you start Oracle Universal Installer. If you are, only the root user will have permissions to manage Oracle Procedural Gateway for WebSphere MQ.

   
   

   1. Log in as the Oracle Procedural Gateway for WebSphere MQ user.

   2. Start Oracle Universal Installer by entering:

      prompt> mount_point/runInstaller
      
      

This launches Oracle Universal Installer using which you can install Oracle Procedural Gateway for WebSphere MQ.
