Summary :
In SAP environments, transaction ST06/OS07 may not display historical data for some servers if their names exceed 8 characters and share identical initial sequences. The issue originates from limitations in the MONI and OSMON tables which store server names up to 8 characters only. Problems include incorrect server name abbreviations due to a software glitch in SAPWLSERV, truncation in SAPDBHOST, and use of rfchost within RFC_SYSTEM_INFO. Solutions involve consulting specific SAP Notes for corrections (Notes 337585, 764684, and 956213), ensuring unique 8-character identifiers, or using SAPLOCALHOST parameter for logical naming through an SAPccmsr agent. Ensuring unique server identifiers is crucial for correct system monitoring.
