Error description
The message subsystem does not reuse message buffers obtained in ECSA efficiently. This enhancement will cap the amount of ECSA the message subsystem will use as well as reuse previously obtained ECSA buffers.

Problem summary
**************************************************************** * USERS AFFECTED: OMEGAMON XE for DB2 PE/DB2PM * * users of component * * - OMEGAMON Server * * - Classic Interface * **************************************************************** * PROBLEM DESCRIPTION: 1. OMEGAMON message subsystem loads * * routines to ECSA that can only be * * removed or refreshed by an IPL. * * 2. OMEGAMON message subsystem leaves * * E/CSA virtual storage allocated on * * subsequent OMPE Collector start up. * * 3. OMEGAMON message subsystem may use * * excessive ECSA. * **************************************************************** * RECOMMENDATION: Apply this PTF * **************************************************************** PROBLEM SUMMARY: 1. The OMEGAMON message subsystem remains active on subsequent OMPE Collector start. When maintenance effects these routines an IPL is required to prevent incompatible levels of modules. 2. The OMEGAMON message subsystem does not properly manage E/CSA virtual storage on subsequent OMPE Collector start up. 3. During processing the message subsystem may GETMAIN excessive ECSA. PROBLEM CONCLUSION: 1. Upon restart of OMPE, internally cycle the message subsystem to avoid the need for IPL when maintenance effects the message subsystem routines. 2. Enhance message subsystem E/CSA buffer management. 3. Cap the amount of E/CSA used by the OMEGAMON message subsystem. KEYWORDS: OMEGAMON-MESSAGE-SUBSYSTEM
