The PSSAMSRV server process communicates through the Tuxedo conversational mode. It performs transactional SQL requests (updates).

Min Instances

Enter how many servers are started at boot time. This translates to the PSSAMSRV server's -m (min) parameter in the UBB file.

Max Instances

Enter the maximum number of servers that can be started. This translates to the PSSAMSRV server's -M (Max) parameter in the UBB file.

Service Timeout

Enter the number of seconds that the server processes waits for a request before timing out. This stops runaway processes, like an rccbl timeout.

Recycle Count

Enter the number of service requests that each server carries out before being terminated (intentionally). Tuxedo immediately restarts the server. Servers must be intermittently recycled to clear buffer areas. The time that is required to recycle a server is negligible, occurring in milliseconds. The recycle count does not translate into a native Tuxedo parameter in the PSAPPSRV.UBB file. Instead, the value is stored in memory and is managed by a PeopleSoft server.

Allowed Consec Service Failures

Enter a number greater than zero to enable dynamic server process restarts for service failures. To disable this option, enter 0. The default is 2. The value that you enter is the number of consecutive service failures that cause a recycle of the server process. This is a catchall error handling routine that enables PSAPPSRV, PSQCKSRV, and PSSAMSRV to terminate themselves if they receive multiple, consecutive, fatal error messages from service routines. Such errors should not occur consecutively, but if they do, the server process must be recycled or cleansed. A retry message appears on the client browser when this occurs.

Max Fetch Size

The default is 32 (K). Enter the maximum memory that is used by the server to store fetched rows for a transaction before sending results to the client and refilling the memory buffer. When the memory limit is reached, the server sends rows to the client, but then resumes refilling the buffer and sending results to the client until the query is complete. You should leave the default value unchanged.

PSSAMSRV supports conversational transactions, so this parameter enables users to tune performance by adjusting the number of network round-trips that are required for the average transaction. A value of 0 causes unlimited memory to be used, which means one round-trip no matter how large the result set. The memory is not preallocated, but is acquired as needed.
