Setting up the ADCD package

Before you configure Z instances, set up the ADCD package.

When you run the installer, a non-root user ID (ibmsys1) is created. The user ID is required to enable the z/OS® images. You can also create other non-root user IDs.

To set up the ADCD package, complete the following steps:

Switch to the non-root user ID (ibmsys1).
Create a folder that is named volumes under /home/ibmsys1, and keep all ADCD volumes in the non-root user directory that you downloaded at step 2 of Checklist.
Decompress all .gz volumes by using the Linux® command.
```
gunzip *.gz
```

Set the environment variables by using the following command.

export PATH=/usr/z1090/bin:$PATH
export LD_LIBRARY_PATH=/usr/z1090/bin:$LD_LIBRARY_PATH
export MANPATH=/usr/z1090/man:$MANPATH
ulimit -c unlimited
ulimit -d unlimited

Decrypt .ZPD volumes by using the command from /usr/z1090/bin:

./Z1091_ADCD_install <path of volume>/C4RES1.ZPD <output path of volume>/C4RES1

For example:

./Z1091_ADCD_install
/home/ibmsys1/volumes/C4RES1.ZPD
/home/ibmsys1/volumes/C4RES1

Make sure that all volumes are owned by the non-root user ID. You can use the following command to change the owner and group.
```
chown ibmsys1 *
chgrp zpdt *
```
Note: Make sure that the folder that contains *.gz and .ZPD volumes are also owned by the non-root user ID.
Make sure that all volumes are executable. Otherwise, enter the following command:
```
chmod 755 *
```
