Directory Server Connection Pool
Log
Definition
The user management engine (UME) can use a directory server as a data source. The UME accesses the directory server through a number of connections in a connection pool. The directory server connection pool log takes a snapshot of the connections in the connection pool, reporting their state: idle or in use. You can configure how often the system records the state of the connections. The UME creates a separate log for each connection pool. There is a connection pool for each object class configured.
Use
You can use the directory server connection pool log to monitor how the directory server connections in the pool are being used. This enables you to troubleshoot connection problems and optimize performance.
To enable the directory server connection pool log, configure the setting Monitoring Interval. For more information, see Configuring the UME to Use an LDAP Directory as Data Source.
This log does not have a maximum file size. Disable the log when you no longer need it.
To view the log files, use any text editor.
Structure
When enabled, the UME creates the directory server connection pool log file, sapum_cpmon_<hostname>_<port>_<object_ID>.log, in the following location:
<drive:>\usr\sap\<SID>\<instance>\j2ee\cluster\server<n>
The file name uses the following syntax:
sap.um_cpmon_<hostname>_<port>_<objectID>.log
Hostname and port refer to the directory server. Object ID refers to the object class; the default values are GRUP, UACC, and USER.
When you restart the SAP NetWeaver Application Server (AS) Java, the system overwrites the log files.
