Chapter 4 Target Promotions : Applying Change Requests To The Target System

Applying Change Requests To The Target System
You can apply change requests interactively or as a batch job. In either case, you must consider the potential issues that can develop during target promotions. For more information, refer to Considerations When Applying Target Promotions and Disposition of Objects.
Managing Impact To Users
Promotions and backing out of change requests can change the behavior of one or many of your applications. For more information, refer to Chapter 1, Introduction to Administration of Promotions.
Sequence of Events
When you apply change requests on a target system the following process is initiated:
1.
This check ensures that objects marked as new are in fact new and objects to be modified or deleted do actually exist. If validation is successful, the change request status is set to V (verified). If the validation is unsuccessful, the promotion fails and you get an error message. For more information on object dispositions, refer to Disposition of Objects.
2.
When a back up is completed, the change request status is set to S (saved).
3.
Applying Change Requests
To apply change requests, enter one of the following line commands in the Apply Change Requests screen:
B
All object sets that are to be modified by the target promotion must be disabled. Deviation from this requirement could result in serious security complications.
Segment Number Prompt
When you issue the A line command to apply a change request interactively, the Promotion system prompts you to confirm the Apply request and to enter target segment numbers for new TDS tables. If no value is entered, the default is segment 0.
Establishing the Segment Number
The Promotion system performs the following sequence of checks to establish the segment number:
1.
If this fails, it performs check number 2.
2.
If this fails, it performs check number 3.
3.
If you inadvertently created tables in segment 0, change the segment number immediately using the MOVTAB tool. You can also use the Table Definer from the administrator’s workbench.

Promotion Log
When change requests are promoted, the Promotion system provides a log of its activities. Review any warning and error messages associated with each promotion request. All messages are documented in TIBCO Object Service Broker Messages With Identifiers.
Saved logs are also available via Query Promotion Information.
Initiating Target Promotions from Rules
In addition to applying change requests interactively and in batch mode, you can initiate promotions using your own TIBCO Object Service Broker rules. For instance, you can decide to automate the promotion process by creating your own application to manage it.
To initiate the promotion of a change request in a target system other than its source, invoke the APPLY_CHANGE rule as in the following example:
APPLY_CHANGE(srclocn, change#, tds_segment,)
Rules Arguments
The arguments for the APPLY_CHANGE rule are defined as follows:
