The unquiesce callable service unquiesces a file system, making the files in it available for use again. The backup of the data in the file system is complete.
Operation | Environment |
---|---|
Authorization: | Supervisor or problem state, any PSW key |
Dispatchable unit mode: | Task |
Cross memory mode: | PASN = HASN |
AMODE (BPX1UQS): | 31-bit |
AMODE (BPX4UQS): | 64-bit |
ASC mode: | Primary mode |
Serialization: | Enabled for interrupts |
Locks: | No locks held |
Control parameters: | All parameters addressable in Primary |
|
AMODE 64 callers use BPX4UQS with the same parameters.
The name of a 44-character field that contains the file system name. The name should be left-justified in the field and padded with blanks.
The name of a fullword binary field that contains the unquiesce service options. This field is mapped by the BPXYMTM macro. Refer to BPXYMTM — Map the modes for mount and unmount for the unquiesce service options that are available.
The name of a fullword in which the unquiesce service returns 0 if the request is successful, or -1 if it is not successful.
Return_code | Explanation |
---|---|
EBUSY | The file system that was specified was not quiesced by this user, and force was not specified in Unquiesce_parms. The following reason code can accompany the return code: JRInvalidRequester. |
EINVAL | An incorrect parameter was specified. Verify that only the force bit in Unquiesce_ parms was specified, that File_system_name is correct, and that File_system_name is for a quiesced file system. The following reason codes can accompany the return code: JRFileSysNotThere, JRInvalidParms, and JRNotQuiesced. |
EPERM | The user cannot request this service, because it lacks the permission required to do so. The following reason code can accompany the return code: JRUserNotPrivileged. |
The name of a fullword in which the unquiesce service stores the reason code. The unquiesce service returns Reason_code only if Return_value is -1. Reason_code further qualifies the Return_code value. For the reason codes, see z/OS UNIX System Services Messages and Codes.
The unquiesce service makes a file system available for use again following a previous quiesce request.
For an example using this callable service, see BPX1UQS (unquiesce) example.
