Creating the integration node directory on z/OS

Create the integration node directory, as a part of creating an integration node on z/OS®.

Before you begin

Use the TSO command OMVS to get into OMVS.
Create the integration node root directory by using the command:
```
 mkdir -p <ComponentDirectory>
```
The name of the directory must be the same as the JCL variable ++COMPONENTDIRECTORY++.
Display the contents of the directory, which is empty, using the command:
```
ls -dl /var/wmqi/MQP1BRK
```
Display the permissions on the directory by using the command:
```
ls -al /var/wmqi/MQP1BRK
```
Ensure that the user ID of the person who does the customization has a group that matches the group of the directory.
Use the following command, where userid is the ID you want to check:
```
id <userid>
```
Check that the directory has a valid group, and that the group has rwx permissions.
If they do not, use the following command to set the group of the directory:
```
chgrp <group> <pathname>
```
For example:
```
chgrp WMQI /var/wmqi/MQP1BRK
```
You must be the owner of the group, or have superuser authority, to use this command.
To give the group READ, WRITE, and EXECUTE access, use the following command:
```
chmod g=rwx <pathname>
```
For example:
```
chmod g=rwx /usr/wmqi/MQP1BRK 
```
To display the amount of space that is used and available, use the following command:
```
df -P /var/wmqi/MQP1BRK
```
