The T_DEVICE
class represents configuration and run-time attributes of raw disk slices or UNIX system files being used to store BEA Tuxedo system device lists. This class allows for the creation and deletion of device list entries within a raw disk slice or UNIX system file.
(k)— |
T_DEVICE
class are local attributes.TA_DEVINDEX
is required for SET
operations to identify the particular device list entry except when setting the state to NEW
for the purpose of creating a new device list entry. In the latter case, TA_DEVINDEX
must not be set; a value will be assigned by the system and returned after a successful creation.TA_DEVSIZE
may only be SET
on object creation.Logical machine identifier where the device is located. Note that this attribute may be used as a key field in both unbooted and booted applications as long as they are already configured (that is, at least one T_MACHINE
entry is defined). It is required as a key field on SET
operations when accessing a booted application. If specified when accessing the T_DEVICE
class in an unconfigured application, this attribute is ignored.
Absolute pathname of the file or device where the BEA Tuxedo filesystem is stored or is to be stored.
The offset, in blocks, at which space on this TA_DEVICE
begins for use within the BEA Tuxedo System VTOC specified by TA_CFGDEVICE
. Limitation: This attribute must be set to 0 for the first device list entry (TA_DEVICE
) on the BEA Tuxedo filesystem (TA_CFGDEVICE
).
The size in pages of the disk area to be used for the device list entry. Limitation: This attribute may be set only in conjunction with a state change to NEW
.
Device index for TA_DEVICE
within the device list addressed by TA_CFGDEVICE
. This attribute value is used for identification purposes only in getting and setting attribute values relating to particular devices within a BEA Tuxedo filesystem.
A GET
operation will retrieve run-time information for the selected T_DEVICE
object(s). The following states indicate the meaning of a TA_STATE
returned in response to a GET
request.
The BEA Tuxedo filesystem indicated by |
A SET
operation will update information for the selected T_DEVICE
object or add the indicated object. The following states indicate the meaning of a TA_STATE
set in a SET
request. States not listed may not be set.
