Getting the code:
You can download the code to your workstation by choosing the IBM 64-bit SDK 1.4 for z/OS file UK36704.PAX.Z.
To assist you with the download, a link to Download Director is available. Download Director is a highly reliable tool designed to resume an interrupted download connection, access files through the firewall, and download large files.
To verify that the download was complete you should determine if the file sizes of the files downloaded match the file sizes listed on the IBM download server web page.
The current size of the files on the IBM server are as follows:
UK36704.PAX.Z 86085 KB 86085089 bytes
Once the file has been downloaded to your workstation, you will need to use a binary transfer to move the file to an HFS directory on your z/OS system with at least 180MB of space.
Prereqs and Recommended Service:
There are no specific APARs required for z/OS V1.7 and above.
The z/OS level should be at the GA level of z/OS V1.6 (5694-AO1) with all the maintenance required/documented in the PSP bucket.
In addition, please be sure to have installed:
- PQ86742 (PTF UQ88825)
- PQ87127 (PTF UQ88986)
- PQ88522 (PTF UQ90946)
- PQ90923 (PTF UQ92626)
- OA08252 (PTF UA13606)
Java will NOT function without these APARs.
The z/OS MEMLIMIT parameter should be set to 256MB or greater.
Note: The MEMLIMIT value may need to be increased depending on what applications are being run.
Uncompress and install the code:
Once you have the code in your HFS directory you will need to uncompress the file to complete the installation.
- Use the PAX command to restore the code archive, as follows:
pax -ppx -rvzf UK36704.PAX.Z
Note: 64-Bit SDK 1.4 comes packaged with the +p bit already set for the files in the "J1.4_64/bin" and "J1.4_64/bin/j9vm" directories.
- The command will create and expand the code in directory J1.4_64.
If you are not able to restore the code archive with this command, it may be because you do not have the necessary authority (see "Required authorization") to restore the program control bit. In this case, you can issue the following command. Please note, certain applications may require that the program control bit be set.
pax -pp -rvzf UK36704.PAX.Z
Required authorization:
To restore the files with the proper permission bits, you must have the following authority:
- - UID(0) or access to BPX.SUPERUSER.FACILITY class
- - Access to BPX.FILEATTR.APF
- - Access to BPX.FILEATTR.PROGCTL
- - Access to BPX.FILEATTR.SHARELIB
Note: Access to BPX.FILEATTR.* could be used instead.
This is the typical authority you require to install z/OS.
Please note, certain applications may require that the program control bit be set.
Verification:
Post Installation Information
If you were successful in downloading and uncompressing all the files, there should be a file titled "JDK_INSTALL_OK" in the directory J1.4_64.
Set the Environment
The installation below assumes you installed the code into the following directory:
/mydir/java
Set the following environment variables:
export PATH=/mydir/java/J1.4_64/bin:$PATH
export DISPLAY=hostname.of.my.machine:0.0
Verify the Install
To verify that the install process completed successfully, issue the following command:
java -version
You will see the following message showing the java version level and other information:
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 2.2)
IBM J9SE VM (build 2.2, J2RE 1.4.2 IBM J9 2.2 z/OS s390x-64
j9mz64142-20080517 (JIT enabled)
J9VM - 20080428_1701_BHdSMr
JIT - r7_level20080115_1845)
The CLASSPATH environment variable can be updated. For example, issue the following command to set the CLASSPATH variable:
export CLASSPATH=.:/path/to/my/classes:$CLASSPATH
In this example, the JVM will first look for the required classes in the current directory. If the required classes are not found there, the JVM will look in the /path/to/my/classes directory.
For more information please see the z/OS Java website.
