Modifying a resource definition

To modify a resource definition in the permanent, autostart, and runtime databases, complete the following steps:

First, delete the resource definition entry from the runtime database by using the command:
```
cicsdelete -c class -r regionName -R key
```
where key is the key name for the resource definition entry. See Commands affecting resource definitions for an explanation of the other options that are associated with this command.
Then, modify the resource definition entry in the permanent database and install it in the runtime database using the command:
```
cicsupdate -c class -r regionName -B key \
           attribute=value \
           .
           .
           .
           attribute=value
```
where key is the key name for the resource definition entry. See Commands affecting resource definitions for an explanation of the other options that are associated with this command.

Note: When a resource definition already exists in the runtime database, you must delete it first before updating the definition in the permanent database.
