Controlling adding a data set to a LNKLST set

To control who can add a data set to a LNKLST set, the RACF® security administrator can take the following steps:

To establish a profile for the LNKLST set name for the FACILITY class, issue RDEFINE:
```
RDEFINE FACILITY CSVDYNL.lnklstname.ADD UACC(NONE)
```
where lnklstname is the name of the LNKLST set. For example,
```
MYLNKLST.SET
```
You can use generic characters for the qualifiers in the LNKLST set name. For example,
```
CSVDYNL.MYLNK*
```
If you have RACF 1.9 or higher installed, you can use the following generic to cover all LNKLST set names:
```
CSVDYNL.**
```
To ensure that generic profile checking is in effect for the class FACILITY, issue the following command:
```
SETROPTS GENERIC(FACILITY)
```
For coverage of LNKLST sets, check the names currently specified in the PROGxx parmlib members. Also use the DISPLAY PROG,LNKLST system command.
To permit the user (in this example user OPER1) to add a data set to LNKLST set l, issue the following:
```
PERMIT CSVDYNL.l.ADD CLASS(FACILITY) ID(OPER1) ACCESS(UPDATE)
```
OPER1 must be the name of a RACF-defined user or group profile.

Note: Instead of specifying individual userids, you can specify the name of a RACF group profile and connect authorized users to the group. See Defining RACF profiles.
If the FACILITY class is not already active, issue the SETROPTS command as follows:
```
SETROPTS CLASSACT(FACILITY)
```
(To ensure that the FACILITY class is active, you can issue the SETROPTS LIST command.)
To refresh the FACILITY resource class, issue SETROPTS RACLIST:
```
SETROPTS RACLIST(FACILITY) REFRESH
```
