Example

For example, you may be running an Adaptive Server Enterprise server on a

 

UNIX system that holds the consolidated database, but wish to deploy

 

remote databases on laptop computers running some flavor of Windows.

In this circumstance, you have several options for the platforms on which you extract the database, including the following, assuming you have the requisite software:

Run the extraction utility on UNIX to create the reload script and data files. Copy the script and data files to a Windows machine. Create the Adaptive Server Anywhere databases and load them up with the schema and data on Windows.

Run the extraction utility on UNIX to create the reload script and data files. Create the Adaptive Server Anywhere databases and load them up with the schema and data on the same UNIX platform, and then copy the database files onto Windows machines for deployment.

Run the extraction utility on Windows, and carry out all database creation and other tasks on the Windows operating system.

Notes on synchronization and extraction

Extracting large numbers of subscriptions, or synchronizing subscriptions to large, frequently-used tables, can slow down database access for other users. You may wish to extract such subscriptions when the database is not in heavy use. This happens automatically if you use a SEND AT clause with a quiet time specified.

Synchronization applies to an entire subscription. There is currently no straightforward way of synchronizing a single table.

For performance tips for Adaptive Server Enterprise users using a subscription-listcolumn, see “Tuning extraction performance” on page 155 and “Tuning extraction performance for shared rows” on page 162 .
