How to tell the last time a table was updated
I know I could do this with a trigger, but I was wondering if there is a data dictionary view I can query to find the date/time a table was last updated. What I have is a table that is constantly getting hammered with new data being uploaded from a third party. We need to keep close tabs to verify that this datafeed is constantly running and bringing in new data. Because the data that comes in comes from multiple timezones and there are hundreds of lines, our attempts at monitoring by just looking at the data leave something to be desired.
Any ideas?

How to get the last time a record was modified or created ?
Is there a way (hidden system fields for example, system view, other ?) to get the last time a record of a table was modified or the date it was created.
Thanks for any help.

If I never synced to itunes and I restore the device. Will I lose unstored data? How can I check to see the last time my phone was backed up if I forgot the passcode to my phone?
If you can't remember your passcode, you'll need to restore your phone. If you never synched to iTunes, all data on your phone will be erased. No way around this.

HT201269 How do I see the last time my phone was backed up?
My iphone has gone dark. I was planning on getting a new phone but I can't turn my old phone on to transfer data. How can I see the last time my phone was back up?
If you back up to iTunes, open iTunes on your computer. Go to Preferences (from the leftmost item in iTunes' menu bar), then choose "Devices". The backup time will be shown there.
If you back up to iCloud, you would be able to see it on your iPhone, but since you can't turn it on, I don't think there is another way to find it. -
My iPad was either stolen or lost and was in my luggage. Is there a way to tell the last time it was turned on. If so this will tell me if anyone has it.
If you have an iCloud account and Find My Device was enabled on the iPad, you could try to find it using the iCloud.com web site. Otherwise there is no way to find it.
You need to change all your online passwords immediately; notify the airport at which it went missing from your luggage (assuming it was at an airport); notify the police; notify your insurance company so you can get reimbursed and buy a new one; move on. -

When was the last time a program was run?
Experts, is there a way to know when was the last time a program was run (particularly, Z Program). We are trying to identify obsolete programs and avoid working on those programs that weren't touched for more than 3 years during our next upgrade. How can I find this? Any suggestion would be highly appreciated.
Thank you.Hi,
One way is to check TRDIR table(se11/se16) and display it. In the next screen once you will get 'Data Browser Table TRDIR' selection screen. There either you put the individual 'Z' program name in the 'Name' field & execute it or for all multiple entries execute it.
Once you execute it with the particular Z prog. name then you will get the required details like CDAT(Created on),UNAM(Last changed by),UDAT(Changed On),SDATE(Standard selection screen generation: Date),IDATE(Selection screen generation: Date) etc.
Hope this can help you. -
The last time an index was used
Hi to all,
I would like to know, if there is a way of knowing the last time an index was used, or what indexes have never been used.
Regards

Correo [email protected]Hi Eduardo,
reading through the updates from Thomas and Volker, I was wondering if there was a bug in i5/OS that causes the "Last used date" information in the file description not to be updated properly for indexes. If you have the plan cache dump or database monitor active (i.e. quite current data in ST04), you could do the following to find out if indexes have been used by the SAP system without a proper update in the file description:
1. List all indexes into a temporary output file:
DSPFD FILE(R3<sid>DATA/ALL) TYPE(MBR) OUTPUT(*OUTFILE)
FILEATR(*LF) OUTFILE(QTEMP/DSPFD)
2. Compare output with database monitor data using STRSQL or SQLUTIL:
SELECT T1.MBFILE, T1.MBUDAT, T2.QQTIME, T2.QQLIFN
FROM QTEMP/DSPFD T1, R3<sid>DATA/SQ3001_DB4 T2,
R3<sid>DATA/SYSINDEXES T3
WHERE T1.MBFILE = T3.SYSTEM_INDEX_NAME
AND T3.INDEX_NAME = T2.QQLIFN
ORDER BY T1.MBUDAT
If you find indexes, where the "Last Used Date" is smaller than the QQTIME value, you know that the
file statistics are not updated properly. You could then open a PMR at IBM for that.
On one of our internal systems I did not see a discrepancy, so it seems to me that the information is correct. Volker's experiences could be explained by the fact that indexes are not just used to implement SQL statements, but also for table statistics. I assume that the "Last used date" is not updated when the index was only used to obtain table statistics. With incomplete statistics, the optimizer may choose a different join order or access method, which can result in poor performance. So there is some risk involved when dropping an index that has a very old "Last used date", and you can only decide it by trying (with care!).
Kind regards,

I can get the last time a patch was applied. What I need is this info for ALL servers.
Getting the last time a server was patched is a simple, single line of PowerShell:
get-hotfix -computername seadcweb10 | sort InstalledOn | select -last 1
What I need is to get a list of *all* the servers in Active Directory, and get this information for each.
I've tried variations of foreach , but I get errors.
foreach ( $p in Get-ADComputer -Filter 'OperatingSystem -like "Windows *Server*"' ) { get-hotfix -computername $p.Name | select -last 1 }
Get-HotFix : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
At line:1 char:97
+ foreach ( $p in Get-ADComputer -Filter 'OperatingSystem -like "Windows *Server*"' ) { get-hotfix <<<< -computername
$p.Name | select -last 1 }
+ CategoryInfo : NotSpecified: (:) [Get-HotFix], COMException
+ FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,Microsoft.PowerShell.Commands.GetHotFixCommand
What am I doing wrong?Hi
The RPC server is unavailable
This error comes when any server is not pingable.
Make sure you are able to ping to all server from the server you are running the script.
Then give a try to below script :
foreach ( $p in Get-ADComputer -Filter {OperatingSystem -like "Windows *Server*"})
get-hotfix -computername $p.Name | select -last 1

When the last time a datafile was used
Hello.
This is from Solaris box, running Oracle 8.1.7.4.0.
There are two datafiles, actually three, that were created for three tablespaces. These in total take up more than 3G on the server and space is at a premium.
I suspect that these files can be removed but I need to understand when the last time they were used and if it is safe to remove them.
Each of these files was created as 800M files and each has 799.99M remaining.
Thank you for any advice.
DAit doeasn't help when you use ls -l, because the system checkpoint will upate all the datafiles(except the readonly ones)
SQL> create tablespace myts datafile '/tmp/myts.dbf' size 50M;
Tablespace created.
SQL> create table mytable1 (col1 date, col2 number) tablespace myts;
Table created.
SQL> !ls -ltr /tmp/*.dbf
-rw-r----- 1 oracle oinstall 52436992 Apr 18 09:22 /tmp/myts.dbf
SQL> alter system switch logfile;
System altered.
SQL> !ls -ltr /tmp/*.dbf
-rw-r----- 1 oracle oinstall 52436992 Apr 18 09:22 /tmp/myts.dbf
SQL> alter system checkpoint;
System altered.
SQL> !ls -ltr /tmp/*.dbf
-rw-r----- 1 oracle oinstall 52436992 Apr 18 09:24 /tmp/myts.dbf
if you want to drop the tablespace, just simply run the following command. it should be successful if your TS is empty:
SQL> drop tablespace myts;
drop tablespace myts
ERROR at line 1:
ORA-01549: tablespace not empty, use INCLUDING CONTENTS option
SQL> select segment_name,segment_type from dba_segments where tablespace_name='MYTS';
SEGMENT_NAME
SEGMENT_TYPE
MYTABLE1
TABLE
SQL> drop table MYTABLE1 purge;
Table dropped.
SQL> drop tablespace myts;
Tablespace dropped.
Or you can run the following command directly if you confirm to drop everything in this TS:
drop tablespace myts INCLUDING CONTENTS ;
