What is the retention period for DDMDB event tables?

[MARUBUN SUPPORT]

Hi Team,

Product
OS：RHEL9.5
Spectrum 24.3.9

A customer has asked me a question, so I would appreciate some advice.

The DDMDB event table is a partitioned table, but how many days is the default retention period for the DDMDB event table?
Also, is it possible to change the retention period for the DDMDB event table?
If it is possible to change the retention period, please tell me how to do it.

The background to this is that the customer's system has a large number of events, which is putting pressure on the disk.
They are planning to expand the disk, but they do not have much space to spare, so they would like to know if there is a temporary solution until then.

I am aware that the ReprotDB can be changed from the OneClick web management screen by going to [Management] → [Report Manager] → [Basic Settings], but I was wondering if a similar or similar setting is possible in DDMDB, so I asked the question.

Regards,
MARUBUN

Default value for storing DDMDB events is 45 days. It can be modified under $SPECROOT/SS/DDM/.configrc.

The 2 relevant parameters are:

---

MAX_STAT_DAYS=45
MAX_EVENT_DAYS=45

---

There are some queries mentioned that can help you decide which period is optime for your installation.
