Set File Availability

You can put a file on hold, causing CA-L-Serv to put requests for that file into a queue until the file is released. To do this, issue this command:
```
HOLDFILE   ddname
```
When you are ready to restore normal I/O processing for the file, you can release it by issuing this command:
```
RELEASEFILE   ddname
```
You can make a file unavailable to any job, so that all requests for it fail, by issuing this command:
```
CLOSEFILE   ddname
```
When you are ready to restore normal I/O processing for the file, you can make the file available by issuing this command:
```
OPENFILE   ddname
```
You can remove a CA-L-Serv file from the management of CA-L-Serv by issuing:
```
REMOVEFILE   ddname
```
This command does not delete a file it simply removes the file from the management of CA-L-Serv. The file is first closed, and then deallocated (if it was dynamically allocated).

Important! The HOLDFILE, and CLOSEFILE commands are not needed under normal circumstances. Use them only in consultation with CA Support.
