Amazon SimpleDB - Create session
Declaration
<AMAWSSIMPLEDB ACTIVITY="create_session" SESSION="text" ACCESSKEY="text" SECRETKEY="text (encrypted)" USERAGENT="text" MAXERRORRETRY="number" SERVICEURL="text" PROXYHOST="text" PROXYPORT="number" PROXYUSER="text" PROXYPWD="text (encrypted)" SIGNMETHOD="text" SIGNVERSION="number" />
Description: Creates a unique session which can be used to associate subsequent Amazon SimpleDB steps. This provides a single task the ability to execute multiple SimpleDB operations, each set of operations associated to a specific session.
Practical Usage
Ideally used to create a session to correlate subsequent Amazon SimpleDB activities to. Creating a session eliminates having to re-enter specific requirements for each activity. A single task can include multiple sessions. To end a session, use the End Session activity.

Description |
|---|---|---|---|---|---|
|
Access key |
Text |
Yes if connection is host-based |
(Empty) |
ACCESSKEY= "022QF06E7MXBSH9DHM02" |
A 20-character alphanumeric string that uniquely identifies the owner of the AWS service account, similar to a username. This key along with a corresponding secret access key forms a secure information set that AWS uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host. |
|
Secret Access key |
Text |
Yes if connection is host-based |
(Empty) |
SECRETKEY= "kWcrlUX5JEDGM/LtmEENI/ aVmYvHNif5zB+d9+ct" |
A 40-character string that serves the role as password to access the AWS service account. This along with an associated access key forms a secure information set that SQS uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host. |
|
Session |
Text |
Yes if connection is session-based |
SQSSession1 |
SESSION="SimpleDBSession1" |
Specifies the session name to create for this activity. Subsequent SimpleDB activities can be linked to this session allowing several SimpleDB operations (that may contain multiple activities) to be performed within a single task. The default session name is 'SimpleDBSession1'. NOTE: Make sure to use an End session activity to mark the end a particular session. |

|
User agent |
Text |
No |
AutoMate |
USERAGENT="AutoMate" |
The name of the client or application initiating requests to AWS, which in this case, is AutoMate. This parameter's default value is 'AutoMate'. |
|
Service URL |
Text |
No |
(Empty) |
SERVICEURL= "https://sdb.eu-west-1.amazonaws.com" |
The URL that provides the service endpoint. To make the service call to a different region, you can pass the region-specific endpoint URL. For example, entering https://sdb.us-west-1.amazonaws.com points to US West (Northern California) region. A complete list of SQS regions, along with their associated endpoints and valid protocols can be found below under SimpleDB Endpoints and Regions. |
|
Maximum retry on error |
Number |
No |
(Empty) |
MAXERRORRETRY="4" |
The total amount of times this activity should retry its request to the server before returning an error. Network components can generate errors anytime in the life of a request, thus, implementing retries can increase reliability. |
|
Proxy host |
Text |
No |
(Empty) |
PROXYHOST="proxy.host.com" |
The host name (e.g., server.domain.com) or IP address (e.g., xxx.xxx.xxx.xxx) of the proxy server to use when connecting to AWS. |
|
Proxy port |
Number |
No |
(Empty) |
PROXYPORT="1028" |
The port that should be used to connect to the proxy server. |
|
Proxy username |
Text |
No |
(Empty) |
PROXYUSER="username" |
The username that should be used to authenticate connection with the proxy server (if required). |
|
Proxy password |
Text |
No |
(Empty) |
PROXYPWD="encrypted" |
The password that should be used to authenticate connection with the proxy server (if required). |
|
Signature method |
Text |
No |
(Empty) |
SIGNMETHOD="HmacSHA256" |
The signature method to use for signing the request. This provides a valid hashing algorithm for signature calculation. Acceptable AWS signature methods are HmacSHA1 and HmacSHA256. |
|
Signature version |
Number |
No |
(Empty) |
SIGNVERSION="2" |
The signature version for signing the request. Valid AWS signature versions are 2 and 4. The difference with version 4 is that it allows you to sign your message using a key that is derived from your secret access key rather than using the secret access key itself. |
Description tab - A custom description can be provided on the Description tab to convey additional information or share special notes about a task step.
Error Causes tab - Specify how this step should behave upon the occurrence of an error. (Refer to Task Builder > Error Causes Tab for details.)
On Error tab - Specify what AWE should do if this step encounters an error as defined on the Error Causes tab. (Refer to Task Builder > On Error Tab for details.)
