HOW TO INSTALL 5770-JV1 OPTION 19 LPP ON THE IBM I OS

You will want to first download the .zip file to your PC per the instructions above, create the directory /jdk11 (MKDIR '/jdk11') on your IBM i server, and transfer the .zip file to the IFS directory, /jdk11, you just created.  This can be done using a mapped network drive, FTP, or IBM i Nav IFS connection).
Please refer to the following file names based on your IBM i OS VRM.
IBM i 7.4: Developer_Kit_for_Java_11_64bit_5770_JV1_LCD8_2628_00.iso.ZIP
IBM i 7.3: Developer_Kit_for_Java_11_64bit_5770_JV1_LCD8_2508_00.iso.ZIP
Then, extract the ISO image file to the IFS.
NOTE: The following commands use the file name for IBM i 7.4.  If you are installing on IBM i 7.3 OS, you will need to change the file name in the commands below accordingly.
1) STRQSH
2) cd /jdk11
3) jar xvf Developer_Kit_for_Java_11_64bit_5770_JV1_LCD8_2628_00.iso.ZIP
4) F12
Once the ISO image files have been extracted from the .zip files, use the instructions below for installing JDK 11 using an image catalog from an IBM i CL command line.
5) CHGOPTA EXTMEDFMT(*YES)
Important Note: The CHGOPTA command must be issued before the LODIMGCLG command shown below. If it is issued after the LODIMGCLG command, you will need to re-load the catalog.
6) CRTIMGCLG IMGCLG(jdk11) DIR('/jdk11/IMAGE') CRTDIR(*YES)
7) ADDIMGCLGE IMGCLG(jdk11) FROMFILE('/jdk11/Developer_Kit_for_Java_11_64bit_5770_JV1_LCD8_2628_00.iso') TOFILE(*fromfile)
8) CRTDEVOPT DEVD(OPTVRT01) RSRCNAME(*VRT) NOTE: If the OPTVRT01 device description already exists, please continue to the next step.
9) VRYCFG CFGOBJ(OPTVRT01) CFGTYPE(*DEV) STATUS(*ON)
10) LODIMGCLG IMGCLG(jdk11) DEV(OPTVRT01)
