Welcome to this Ask the Expert discussion. In this session we will be covering Captiva: Is your system healthy? What to look for to make sure your system is performing optimally? Among the many areas we’ll be discussing, our experts will answer your questions in regards to best practice sizing and tuning considerations centered around the “Captiva Capture 7.1 Performance Sizing and Tuning Guide”, broken down into Client, Server, Database, Licensing, and Reporting performance recommendations.

This Ask the Expert discussion is now open for questions and comments. we look forward to a lively and interactive discussion on Captiva Health.
To keep your system healthy run a row count on all tables in your database and identify the large tables. Large is anything over a million rows. If you find some make sure they are only reporting tables and that the tables are being purged through Captiva Administrator.
Yes. Also, if you have Audits enabled, expect the database to grow very quickly and overall InputAccel Server performance to degrade. Hence, it is very critical to schedule a periodic purge of the Audit Logs to avoid the InputAccel Database from growing too large too quickly.
One key cause of performance issues is a slow disk system. If it seems like a possible cause in your case, it's worth running the PixSafeTestApp utility, which you can obtain from Support, to check the speed of the disk - any returned value above 100 is slow, although a good disk generally returns less than 60.
If your disk is found to be slow, bear in mind that RAID 5 is not recommended because of its slow performance, but RAID 10 is faster and equally fault tolerant. Also, bear in mind that using a NAS or any form of shared folder (UNC path) for the IAS root is not recommended for several reasons, one of which is poor performance, because the IA server makes heavy use of this folder and the throughput of an Ethernet connection is much less than that of a native disk controller.
Have you ever thought why isn’t my Captiva Server processing tasks faster? We all look at server logs (debug.out) looking for trouble, but have you looked in your Data Access Layer (DAL) logs? These logs show you long running queries and queries that update lots of data.
When using Dispatcher, don’t forget to send your Dispatcher project to production using the “send to production” button (ctrl+P) in Dispatcher Manager. This streamlines the project by removing unnecessary files (such as the template image base), thus reducing the project size and the time for it to be loaded into memory when starting a task.
Send to production can also be used when using Captiva Advanced Recognition: Set the send to production folder of your recognition project to the same path as the RecognitionProjectSharedDirectory value in the File management section of GlobalOptions in the System Configuration tab (Captiva Designer) to ensure your project doesn't become too cumbersome.
