Behavior Changes (9.5.1)

Behavior Changes (9.5.1)

This section describes behavior changes in version 9.5.1.

Caching

Effective in version 9.5.1, you specify the total cache size in the --cacheSize option in the InstallTests and RunTests DVOCmd commands. The PowerCenter Integration Service divides the cache size among all Aggregator, Joiner, Lookup, and Sorter transformations in the underlying PowerCenter session. The PowerCenter Integration Service allocates cache memory based on the transformation requirements, such as the number of rows processed, number of tests, and precision and scale of the table columns.
Previously, the cache size that you specified in the command option was the cache size for each transformation, except the Sorter transformation. Data Validation Option assigned 8 MB for each Sorter transformation. For example, if you set the cache size to 200 MB and the session contained two Aggregator transformations, two Joiner transformations, and one Sorter transformation, then each Aggregator and Joiner transformation received 200 MB of cache memory and the Sorter transformation received 8 MB of cache memory.

Connections

Effective in version 9.5.1, connections appear in alphabetic order.
Previously, connections were not sorted alphabetically.

JasperReports Configuration

Effective in version 9.5.1, you do not have to re-enter JasperReports configuration after you disable JasperReports.
Previously, when you disabled JasperReports, the Data Validation Option Client deleted the previous configuration.

Lookup Views

Effective in version 9.5.1, you cannot enter an expression for the Lookup field in a lookup view if the lookup table is from any of the following data source types: flat file, mainframe flat file, ADABAS, IMS, or VSAM.
Previously, you could enter an expression, but an error occurred when you ran a test on the lookup view.
If the lookup table is from a flat file, mainframe flat file, ADABAS, IMS, or VSAM data source and you upgrade to 9.5.1, you must delete the expression from the Lookup field in the lookup view.

Metadata Refresh

Effective in version 9.5.1, Informatica significantly improved repository refresh performance for networks with high latency between the Data Validation Option Client and the Data Validation Option repository.

Repository Selection

Effective in version 9.5.1, you can select a repository faster when you have a large number of repositories, such as 10,000 repositories, defined in the Data Validation Option Client.
Previously, it took a few seconds to select a repository when a large number of repositories were defined in the Data Validation Option Client.
