ZCM 11SP2 slow device deleting

ZCM 11sp2 2 primary server
remote DB server Sybase 12
When I delete a device from either primary servers it takes over 5 min's to delete and the DB server CPU goes to 100% the hole time until the device is removed. Before we upgrade (10.3.4) did not have this problem, device remove quick. With the device getting remove I have no ideal what to look for to see why it is taking so long to delete a workstation.:confused:

Worth checking the database sizing as a starting point:

I have the same problem. I was about to delete 1200 dups, but even a
zman command in batch mode took several hours.
Database was also freshly rebuild and with tons of ressources.
Everything else runs smoothly. It must be a 11.2.1 anomaly.

Re: ZCM 11SP2 slow device deleting

I may open an SR on this as well. We're using external Oracle and even deleting ONE device can take 10-15 minutes.

However, our DBA is reporting that Novell's not using/setting up the database properly (something about
right now the indexes and the tables are in the same tablespace, although there are separate tablespaces for each... good design but it's not being implemented ???
)

Re: ZCM 11SP2 slow device deleting

we are seeing the same thing (slow deletes) using the embedded database (11.2.1).. did you hear anything on this ??
only started noticing this slowness when we went to 11.2.1 from 11.2

I only just got the Oracle Redo log stuff today and forwarded them on to Novell.

Yours might be easier if you open an SR since you're using the Sybase embedded database and don't have to depend upon your DBA to get stuff for you.

kjhurni,

Did you ever open a SR with Novell or find a solution to the slow deleting problem? (We are on 11.2.1 and Oracle 11.2.x)

Yes and No. Sorry that I forgot about this.

Okay, there's one thing you MAY be able to do to make it go faster:

IF you are using ZPM, and have lots of devices (or even if not), change the ZPM Dashboard trending from the default of 30 days to 7. WARNING: Novell/Lumension never tested this with Oracle, so they didn't know this can cause major issues). Novell ASSUMED that Oracle works like MS SQL and that if you change from 30 to 7, and the nightly database maint. runs, that it will not purge 50 million items and THEN commit. Novell ASSUMED that Oracle behaves like MS SQL and does the commits in batches. Oracle does NOT. So IF you do this, make sure you have LOTS of space on your archive partition because Oracle will create LOTS of archive files and fill up your disk until it can execute the final COMMIT.

Your alternative: Truncate the database directly, THEN set to 7 days. (or set to 7 days, and truncate before the nightly cleanup can begin).

In our case, this helped dramatically (it was taking 30+ minutes to delete a single pc)

HOWEVER:

It still takes about 5 minutes to delete a single PC now because of all the inventory tables that need to be updated. Novell has no fix for this yet. I suppose if you have NO (or little) inventory information it should be quicker.

Re: ZCM 11SP2 slow device deleting

Thank you kjhurni!

We do not run ZPM. Last year when we upgraded to 11.2.1 we had numerous database issues. They had us run some stored procedure that took days to finish.
It took about 20 minutes to delete each workstation this afternoon. Now (after hours) it seems like it is going a bit faster but still not what I consider good. I think after we upgrade to 11.2.3a next month I will open a new SR to deal with this.

Thanks for the info. Odds are it's the inventory stuff then. I never did get a good response other than:
a) Change your zone options so that after 30 days (example), the device is removed, not flagged.
b) You want to manually run the SQL scripts to delete workstations, but having to type it in for each workstation is quite tedious, and there's no facility to mass-delete.

But they did say they'd investigate things.
