If + inconsistentName or inconsistentValue is returned, the row + remains in state A. + + (5) depending on the MIB definition for the column/table, + either noError or inconsistentValue may be returned. + + (6) the return value can indicate one of the following + errors: + + wrongValue: because the agent does not support + notInService (e.g., an agent which does not support + createAndWait), or + + inconsistentValue: because the agent is unable to take + the row out of service at this time, perhaps because it + is in use and cannot be de-activated. + + (7) the return value can indicate the following error: + + inconsistentValue: because the agent is unable to + remove the row at this time, perhaps because it is in + use and cannot be de-activated. + + (8) the transition to D can fail, e.g., if the values of the + conceptual row are inconsistent, then the error code would + be inconsistentValue. + + NOTE: Other processing of (this and other varbinds of) the + set request may result in a response other than noError + being returned, e.g., wrongValue, noCreation, etc. + + + Conceptual Row Creation + + There are four potential interactions when creating a + conceptual row: selecting an instance-identifier which is + not in use; creating the conceptual row; initializing any + objects for which the agent does not supply a default; and, + making the conceptual row available for use by the managed + device. + + Interaction 1: Selecting an Instance-Identifier + + The algorithm used to select an instance-identifier varies + for each conceptual row. In some cases, the instance- + identifier is semantically significant, e.g., the + destination address of a route, and a management station + selects the instance-identifier according to the semantics. + + In other cases, the instance-identifier is used solely to + distinguish conceptual rows, and a management station + without specific knowledge of the conceptual row might + examine the instances present in order to determine an + unused instance-identifier. (This approach may be used, but + it is often highly sub-optimal; however, it is also a + questionable practice for a naive management station to + attempt conceptual row creation.) + + Alternately, the MIB module which defines the conceptual row + might provide one or more objects which provide assistance + in determining an unused instance-identifier. For example, + if the conceptual row is indexed by an integer-value, then + an object having an integer-valued SYNTAX clause might be + defined for such a purpose, allowing a management station to + issue a management protocol retrieval operation. In order + to avoid unnecessary collisions between competing management + stations, `adjacent' retrievals of this object should be + different. + + Finally, the management station could select a pseudo-random + number to use as the index. In the event that this index + was already in use and an inconsistentValue was returned in + response to the management protocol set operation, the + management station should simply select a new pseudo-random + number and retry the operation. + + A MIB designer should choose between the two latter + algorithms based on the size of the table (and therefore the + efficiency of each algorithm). For tables in which a large + number of entries are expected, it is recommended that a MIB + object be defined that returns an acceptable index for + creation. For tables with small numbers of entries, it is + recommended that the latter pseudo-random index mechanism be + used. + + Interaction 2: Creating the Conceptual Row + + Once an unused instance-identifier has been selected, the + management station determines if it wishes to create and + activate the conceptual row in one transaction or in a + negotiated set of interactions. + + Interaction 2a: Creating and Activating the Conceptual Row + + The management station must first determine the column + requirements, i.e., it must determine those columns for + which it must or must not provide values. Depending on the + complexity of the table and the management station's + knowledge of the agent's capabilities, this determination + can be made locally by the management station. Alternately, + the management station issues a management protocol get + operation to examine all columns in the conceptual row that + it wishes to create. In response, for each column, there + are three possible outcomes: + + - a value is returned, indicating that some other + management station has already created this conceptual + row. We return to interaction 1. + + - the exception `noSuchInstance' is returned, + indicating that the agent implements the object-type + associated with this column, and that this column in at + least one conceptual row would be accessible in the MIB + view used by the retrieval were it to exist. For those + columns to which the agent provides read-create access, + the `noSuchInstance' exception tells the management + station that it should supply a value for this column + when the conceptual row is to be created. + + - the exception `noSuchObject' is returned, indicating + that the agent does not implement the object-type + associated with this column or that there is no + conceptual row for which this column would be + accessible in the MIB view used by the retrieval. As + such, the management station can not issue any + management protocol set operations to create an + instance of this column. + + Once the column requirements have been determined, a + management protocol set operation is accordingly issued. + This operation also sets the new instance of the status + column to `createAndGo'. + + When the agent processes the set operation, it verifies that + it has sufficient information to make the conceptual row + available for use by the managed device. The information + available to the agent is provided by two sources: the + management protocol set operation which creates the + conceptual row, and, implementation-specific defaults + supplied by the agent (note that an agent must provide + implementation-specific defaults for at least those objects + which it implements as read-only). If there is sufficient + information available, then the conceptual row is created, a + `noError' response is returned, the status column is set to + `active', and no further interactions are necessary (i.e., + interactions 3 and 4 are skipped). If there is insufficient + information, then the conceptual row is not created, and the + set operation fails with an error of `inconsistentValue'. + On this error, the management station can issue a management + protocol retrieval operation to determine if this was + because it failed to specify a value for a required column, + or, because the selected instance of the status column + already existed. In the latter case, we return to + interaction 1. In the former case, the management station + can re-issue the set operation with the additional + information, or begin interaction 2 again using + `createAndWait' in order to negotiate creation of the + conceptual row. + + NOTE WELL + + Regardless of the method used to determine the column + requirements, it is possible that the management + station might deem a column necessary when, in fact, + the agent will not allow that particular columnar + instance to be created or written. In this case, the + management protocol set operation will fail with an + error such as `noCreation' or `notWritable'. In this + case, the management station decides whether it needs + to be able to set a value for that particular columnar + instance. If not, the management station re-issues the + management protocol set operation, but without setting + a value for that particular columnar instance; + otherwise, the management station aborts the row + creation algorithm. + + Interaction 2b: Negotiating the Creation of the Conceptual + Row + + The management station issues a management protocol set + operation which sets the desired instance of the status + column to `createAndWait'. If the agent is unwilling to + process a request of this sort, the set operation fails with + an error of `wrongValue'. (As a consequence, such an agent + must be prepared to accept a single management protocol set + operation, i.e., interaction 2a above, containing all of the + columns indicated by its column requirements.) Otherwise, + the conceptual row is created, a `noError' response is + returned, and the status column is immediately set to either + `notInService' or `notReady', depending on whether it has + sufficient information to (attempt to) make the conceptual + row available for use by the managed device. If there is + sufficient information available, then the status column is + set to `notInService'; otherwise, if there is insufficient + information, then the status column is set to `notReady'. + Regardless, we proceed to interaction 3. + + Interaction 3: Initializing non-defaulted Objects + + The management station must now determine the column + requirements. It issues a management protocol get operation + to examine all columns in the created conceptual row. In + the response, for each column, there are three possible + outcomes: + + - a value is returned, indicating that the agent + implements the object-type associated with this column + and had sufficient information to provide a value. For + those columns to which the agent provides read-create + access (and for which the agent allows their values to + be changed after their creation), a value return tells + the management station that it may issue additional + management protocol set operations, if it desires, in + order to change the value associated with this column. + + - the exception `noSuchInstance' is returned, + indicating that the agent implements the object-type + associated with this column, and that this column in at + least one conceptual row would be accessible in the MIB + view used by the retrieval were it to exist. However, + the agent does not have sufficient information to + provide a value, and until a value is provided, the + conceptual row may not be made available for use by the + managed device. For those columns to which the agent + provides read-create access, the `noSuchInstance' + exception tells the management station that it must + issue additional management protocol set operations, in + order to provide a value associated with this column. + + - the exception `noSuchObject' is returned, indicating + that the agent does not implement the object-type + associated with this column or that there is no + conceptual row for which this column would be + accessible in the MIB view used by the retrieval. As + such, the management station can not issue any + management protocol set operations to create an + instance of this column. + + If the value associated with the status column is + `notReady', then the management station must first deal with + all `noSuchInstance' columns, if any. Having done so, the + value of the status column becomes `notInService', and we + proceed to interaction 4. + + Interaction 4: Making the Conceptual Row Available + + Once the management station is satisfied with the values + associated with the columns of the conceptual row, it issues + a management protocol set operation to set the status column + to `active'. If the agent has sufficient information to + make the conceptual row available for use by the managed + device, the management protocol set operation succeeds (a + `noError' response is returned). Otherwise, the management + protocol set operation fails with an error of + `inconsistentValue'. + + NOTE WELL + + A conceptual row having a status column with value + `notInService' or `notReady' is unavailable to the + managed device. As such, it is possible for the + managed device to create its own instances during the + time between the management protocol set operation + which sets the status column to `createAndWait' and the + management protocol set operation which sets the status + column to `active'. In this case, when the management + protocol set operation is issued to set the status + column to `active', the values held in the agent + supersede those used by the managed device. + + If the management station is prevented from setting the + status column to `active' (e.g., due to management station + or network failure) the conceptual row will be left in the + `notInService' or `notReady' state, consuming resources + indefinitely. The agent must detect conceptual rows that + have been in either state for an abnormally long period of + time and remove them. It is the responsibility of the + DESCRIPTION clause of the status column to indicate what an + abnormally long period of time would be. This period of + time should be long enough to allow for human response time + (including `think time') between the creation of the + conceptual row and the setting of the status to `active'. + In the absence of such information in the DESCRIPTION + clause, it is suggested that this period be approximately 5 + minutes in length. This removal action applies not only to + newly-created rows, but also to previously active rows which + are set to, and left in, the notInService state for a + prolonged period exceeding that which is considered normal + for such a conceptual row. + + Conceptual Row Suspension + + When a conceptual row is `active', the management station + may issue a management protocol set operation which sets the + instance of the status column to `notInService'. If the + agent is unwilling to do so, the set operation fails with an + error of `wrongValue' or `inconsistentValue'. Otherwise, + the conceptual row is taken out of service, and a `noError' + response is returned. It is the responsibility of the + DESCRIPTION clause of the status column to indicate under + what circumstances the status column should be taken out of + service (e.g., in order for the value of some other column + of the same conceptual row to be modified). + + + Conceptual Row Deletion + + For deletion of conceptual rows, a management protocol set + operation is issued which sets the instance of the status + column to `destroy'. This request may be made regardless of + the current value of the status column (e.g., it is possible + to delete conceptual rows which are either `notReady', + `notInService' or `active'.)
