304 IBM Content Manager OnDemand Guide
13.3  Data retrieval performance
All Content Manager OnDemand clients (such as the Windows client, CICS client, IBM 
Content Navigator, ODWEK application programming interfaces (APIs), and structured APIs) 
retrieve data from the Content Manager OnDemand server by using a standard proprietary 
Content Manager OnDemand protocol. From a Content Manager OnDemand server 
perspective, no difference exists between one client and another client.
13.3.1  Data retrieval parameters
Various parameters affect data retrieval performance.
Folder parameters: General tab
In the Content Manager OnDemand Administrator Client, under the Folder parameter and on 
the General tab, the following option is available:
/SM590000Note Search: If the Annotation flags in a document database are set to No in the Advanced 
tab of the General window of the Application Group, this option determines when Content 
Manager OnDemand searches the database for annotations and notifies users that 
annotations exist for the documents that match a query. Content Manager OnDemand 
provides three search and notification methods: 
– Hit List: Content Manager OnDemand searches for annotations when the user runs a 
query. When annotations exist for a document, the client programs display a note icon 
next to it in the document list. This method has a direct performance impact on the 
generation of the document list.
– Retrieve: Content Manager OnDemand searches for annotations when the user 
selects a document for viewing. This method is the default and recommended value.
– Note: Content Manager OnDemand searches for annotations when the user chooses 
the Note option while the user views a document.
Folder parameters: Permissions tab
In the Content Manager OnDemand Administrator Client, under Folder parameters and on 
the Permission tab, the following option is available:
/SM590000Max Hits: Determines the maximum number of hits that are retrieved and transmitted to 
the client. By reducing the maximum number of hits, users are forced to enter queries that 
better match the documents that they are searching for. By reducing the maximum number 
of hits, the system resources are used optimally both in performing the queries and in 
downloading the resulting document list.
TCP/IP considerations
A known Windows configuration setting might affect performance when you connect to a 
Content Manager OnDemand server. During repeated searches and retrievals on a Content 
Manager OnDemand server, many Windows sockets are opened and closed. Two default 
Windows settings might affect heavy traffic between the client and the Content Manager 
OnDemand server:
/SM590000When an application closes a Windows socket, Windows places the socket’s port into 
TIME_WAIT status for 240 seconds; during this time, the port cannot be reused. 
/SM590000Windows limits the number of ports that an application can use to 5000.
