Error description
After the installation of maintenance, the Omegamon XE for DB2 PE on z/OS Server is suffering from repetitive error messages msgFPEV1315I, which are filling up the spool and require the server to be stopped: FPEV1315I DBS NUMBER OF PARALLEL SESSIONS EXCEEDS SPECIFIED MAXIMUM On the PE Client, error messages DGOK1446 (server timeout) and DGO1421 (maximum number of TCP/IP sessions exceeded) are conti- nuously issued. Initial analysis has unveiled two problems but more trace points have to be added to the code to isolate the root cause: 1. PE Client suffers from timeouts causing reconnects. 2. PE Server does not free sessions after they become unused.

Problem summary
**************************************************************** * USERS AFFECTED: OMEGAMON XE for DB2 PE/DB2PM * * users of component: * * - PE Server * * - Performance Expert Client * **************************************************************** * PROBLEM DESCRIPTION: When the same pair of host and port is * * specified more than once during the * * configuration of data collectors on PE * * Client side, all data requests issued * * by the PE Client will be routed to the * * single collector which is uniquely * * identified by the specified host and * * port. * * When multiple log on is performed from * * the PE Client to the misconfigured * * collectors, communication sessions * * between the PE Client and the single * * collector will remain open and the * * maximum amount of available sessions * * will become exhausted over time. * * The server will then repeatedly issue * * message FPEV1315I to the server log and * * the PE Client will display messages * * DGOK1446 and DGO1421. * * * * for V310 * * The service level of the * * OMEGAMON server subtask PESERVER * * FPEV0000I DATA SERVER INITIALIZATION * * FPEV0114I PTF BUILD IS 07.163 * * * * for V410 * * The service level of the * * OMEGAMON server subtask PESERVER * * FPEV0000I DATA SERVER INITIALIZATION * * FPEV0114I PTF BUILD IS 07.163 * * * **************************************************************** * RECOMMENDATION: Apply this PTF * **************************************************************** Multiple use of the same pair of host and port during the PE Client configuration results in misconfigured communication paths between the PE Client and configured collectors. This will result in timeout conditions, leave unused sessions open and finally exhaust the maximum available sessions.
Problem conclusion
The server will respond to the PE Client request, close the communication session and provide the freed session for reuse. KEYWORDS : TIMEOUT FPEV1315I DGOK1446 DGO1421 PE CLIENT MAXIMUM SESSIONS
