2.4 Manager

The data collected by each Agent is sent to the Manger and stored in the PDB.

Four different types of data are held in the PDB, depending on the interval at which the data is collected. The following table shows the retention periods for each of these types of data.

Collection interval	Function that displays this data	Retention period
1 to 10 minutes (Monitor data)	Monitor	3 days
10 minutes (Resource data)	Drill Down On-Demand Report (specified in 10-minute units) Scheduled Report (daily)	7 days
1 hour (Resource data)	On-Demand Report (specified in one-hour units) Scheduled Report (weekly)	6 weeks
24 hours (Resource data)	On-Demand Report (specified in one-day units) Scheduled Report (monthly)	53 weeks

The rest of this section explains the roles of the directories that are used when Managers run.

DsaPDBWriter directory

This is a buffer directory for temporarily storing data that is to be written to the PDB. Data that is received from Agents is temporarily stored in this directory.

The amount of data in this directory will grow continuously if data is received from Agents faster than the Manager can write it to the PDB.

The specific location for this directory is as follows:

Variable file directory\transfer\DsaPDBWriter

/var/opt/FJSVssqc/temp/DsaPDBWriter

BackupPDBinsert directory

This directory holds archive files for backing up the PDB. Refer to Chapter 17, "Maintaining the Operating Environment"for details on backing up the PDB.

The specific location for this directory is as follows:

Variable file directory\spool\BackupPDBinsert

/var/opt/FJSVssqc/BackupPDBinsert
