Monitoring scripts - Crontab - how to ?

HI Gurus,
I`m very interesting how can I execute monitoring scripts in Oracle ?
Let say that I would like to have a script which will monitor Sessions and Queries every few minutes. Does Oracle have any internal crontab ?
In OS crontab script should include system user password to be executed, how to do it without password ? Is there any good way ?

Monitoring script

I created a monitoring script which would run from crontab....Would anyone tell me how I would export Oracle SID in crontab script instead of hard coded it. Thanks.

I do some simple checks for correct number of arguments using "if [[ $# -lt 1 ]]; then..."
This is very simple and doesn't confirm that the arguments are valid.
Example:
if [[ $# -lt 1 ]]; then
print "\n ERROR: You did not specify an Oracle SID."
print "\n Please enter which Oracle SID to import into. \n"
exit 1
else
echo "\n ORACLE_SID = $1 \n"
echo "Do you wish to continue? \n "
    read REPLY
     case $REPLY in
        y|Y) echo "\n test good \n";;
        n|N) echo "\n exiting... \n"; return 1;;
        echo "Invalid response (Bozo). Exiting..."
        echo ""
        return 2;
     esac
fiBut my point was to show a quick and easy solution to the OP for his purposes.
Using "echo $1 |. oraenv" passes the variable to oraenv and sets everything he needs for his purposes.
From the sounds of the OP's question, it didn't seem to have the skills to develop more complex scripts.
Personally, I like to use a special file that I keep updated on all servers.
I call the file 'localsids' and place it in the /var/opt/oracle directory.
I have a similar file called 'allsids', which contains a list of all sids on all servers for when I want to check all databases (e.g., such as for users having DBA role, or something like that).
Then, I check for validity (and can add and remove SIDs from the file at will, (depending on purposes such as blackouts).
I like using a loop for this purpose (SIDFILE='var/opt/oracle/localsids' cat $SIDFILE |while read SID... do....)
Example:
# ==================================================
# check input given against valid sids on this machine
# ==================================================
export SIDFILE='/var/opt/oracle/localsids'
SID=`grep $1 $SIDFILE`
if [ "$SID" = "$1" ]; then
print "\n \"$SID\" verified... \n"
else
print "\n ERROR... \"$1\" is not a valid SID for this machine. \n"
exit 1
fiI have a couple other variations as well.
I think it would be nice if OTN had a more appropriate forum for people like us who like scripting and/or what to share unix skills.

Tablespace growth monitoring script

Hi,
I am done with tablespace growth monitoring script.
But I doesnot know how to configure it in WINDOWS to send alert MAIL.
Is there any utility for mail configuration in windows.
Please suggest any solution ASAP.
Regards,
Thiru

It is called OEM alerts. I think we can have configuration in oracle eneterprise manager grid control for automated warnings for tablespace growth. You just have to read below link :
http://download.oracle.com/docs/cd/B19306_01/server.102/b25159/monitor.htm#i1007180

Database uptime monitoring by either snmp or active monitor script anyone?

Hi,
Has anyone previously setup any type of active monitoring script through whats up gold or an snmp informant type of monitoring script to advise when a database is down or specific process is down?
An example would be like ORACLE_PKG1, and the process is named ora_smon_hrprd88.
This is what the HP-UX “ps” shows:
tpadb01:/# ps -ef | grep -i ora_smon
oracle 13207 1 0 Jan 1 ? 0:29 ora_smon_epprd88
oracle 13281 1 0 Jan 1 ? 1:31 ora_smon_hrprd88
oracle 13635 1 0 Jan 1 ? 1:03 ora_smon_fsprd84
oracle 3620 1 0 Jan 2 ? 0:18 ora_smon_mtprd04
oracle 14586 1 0 Jan 1 ? 0:23 ora_smon_mtprd05
oracle 15223 1 0 Jan 1 ? 0:26 ora_smon_inprd88
oracle 15879 1 0 Jan 1 ? 0:25 ora_smon_epsal88
oracle 16769 1 0 Jan 1 ? 0:52 ora_smon_hrsal88
root 17976 22609 0 10:46:39 ttyp2 0:00 grep -i ora_smon
tpadb01:/#
Not sure if the extra info helps, but you never know. We can set it up to send us database up alerts, but the problem I have is when the listener service is down I can't get my script to finish no matter how I change the values of my script around. I can provide my script if that would help as well. If someone has already done this and is willing to share great!

I would suggest you install OEM Grid Control to monitor your databases. For basic monitoring function it's free. OEM GC works great, it's a little overweight though. It's also use SNMP.
Or you can choose any third party tool like

Folder level script? How can I use field value as a pdf filename in save as dialog box

I read somewhere that if you use a folder level script, you can do things like save a pdf with a specific filename - possibly based on a field name.
How would one set up a folder level script?
How do you execute a script from the PDF?
What code would you use to change the PDF name to the contents of the fFieldName text field?
Or, is this really just impossible to do?

The article is interesting. It suggests you place code like this:
// Page Replacement Function
var ReplaceLastPage = app.trustedFunction( function(cPath) {
app.beginPriv();
this.replacePages(this.numPages-1, cPath); app.endPriv();
In the trusted folder. What is the path of the trusted function(s) that get automatically loaded into Acrobat?
I assume in the example above, function(cPath) is a function inside of the PDF...

An error occcurred on line 105 while executing script 'MOM Backward Compatibility Service State Monitoring Script"

We've been getting the following error for some time now.
An error occurred on line 105 while executing script 'MOM Backward Compatibility Service State Monitoring Script'
Source: Microsoft VBScript runtime error
Description: The remote server machine does not exist or is unavailable: 'GetObject'
One or more workflows were affected by this.
Workflow name: System.Mom.BackwardCompatibility.ServiceStateMonitoring
Instance name: server.domain.local
Instance ID: {INSTANCE}
Management group: GROUP
Unfortunately the instance in question has since been decommissioned and simply does not exist any more.
We're currently on a repeat count of over 350,000 and I would REALLY like to get it stopped. I've had a look at adding an override but that points to the management server rather than the instance itself.
Does anyone have any suggestions?
thanks in advance!

Hi Steven,
There are for option for us to override a monitor ot rule:
For all objects of class:
Class
When you select this option for your override, the override settings apply to all objects in the class at which the rule or monitor is targeted.
For a group
When you select this option for your override, the override settings apply only to members of the group. The rule or monitor without the override settings continues to apply to all objects in the targeted class except for those objects that are also members
of the group used for the override.
When you create a group, you save it to an unsealed management pack. However, an element in an unsealed management pack, such as an override, cannot reference an element in a different unsealed management pack, such as a group. If you are going to use a group
to limit the application of an override, you must either save the group to the same unsealed management pack as the override, or you must seal the management pack that contains the group.
For a specific object of class:
Class
When you select this option for your override, the override settings apply only to the specified object. The rule or monitor without the override settings continues to apply to all other objects in the targeted class.
For all objects of another class
When you select this option for your override, the override settings apply only to objects of a class other than the targeted class. The rule or monitor without the override settings continues to apply to all objects in the targeted class.
Did you try to override it for a specific object of class?

Yan Li

Using action script 2 how can i send a variable value to a dynamic textbox on a different keyframe?

using action script 2 how can i send a variable value to a dynamic textbox on a different keyframe?

Thanks for your swift response.
That sounds like a good solution, but the code I have on frame 2 is this
timer = 0;
countup = function(){
timer++;
countupInterval = setInterval(countup,100);
If I added the same actionscript to frame 3 which has a dynamic textbox with a variable timer attached wouldn't it just put the timer back to 0? What I want is the last known value that was given when it was in frame 2.
I am thinking of temple run here, I am trying to caculate the total distance(set in the timer variable) from the previous try.
Hope this makes sense.

You were writing a row for each drive, I basically just wrote the drive information to an array and looped through that array when adding members. I tested this and it worked for me. Note that you can't have the same value names when you add-member
so I appended a numeral to differentiate them.
I hope this post has helped!

Oracle 9i database monitoring scripts

Hi Friends,
I am asked by my boss to submit weekly reports about the database status.
She wanted something in excel format.
Can you suggest me what reports do I submit?

Can you give me some other scripts that u have?

Oracle 9i comes with Oracle Enterprise Manager. This includes a reporting website with monitoring scripts.
Why write them yourself?My boss want a cumulative report over time, for example : what happened @ 1am,2am,3am on tuesday last week, why is the server so slow that the batch job did not complete as expected? Why was an error occured about a table that can not extend? Ora 1635. I mean you can see in the report that at this certain hour a certain tablespace was full.
oops maybe tablespace sample is not logical :D
say every day I can have excel reports of tablespace space status like:
tablespace_name   used     free     date
TS_DATA          1000K   5000k 1-Oct-2010
TS_DATA          2000K   4000k 2-Oct-2010
TS_DATA          3000K   3000k 3-Oct-2010
TS_DATA          4000K   2000k 4-Oct-2010
TS_DATA          5000K   1000k 5-Oct-2010
TS_DATA          5000K      0k 6-Oct-2010Does Statspack can hold historical data for analysis? say for the last 24 hrs?
Thanks a lot

Monitoring scripts for AlwaysOn Availability Group

Does anyone have any any monitoring scripts for AlwaysOn AG using Transact SQL or stored procedures? I'm not a strong coder and don't know Powershell at all. But if there are some Powershell scripts we may be able to use them. I've
seen the dashboard but that's only good if you're logged onto it.
I'm looking for things like monitoring when a database is suspended, send an alert to us but also tries to do the resume.
Thanks for any info.

Start with this list
http://technet.microsoft.com/en-us/library/ff877954.aspx
Automating the issue resolution has to conform to your operational standards. For example, if you use a file share witness for your quorum configuration and your monitoring tells you that it is offline, do you automate bringing it online or do you escalate
to your infrastructure team so that they can look into it? If the database is suspended or the Availability Group in offline state, do you just bring it online or do you check other dependencies like the quorum configuration and instead perform a forced quorum?
I'm a big fan of automation but make sure you define your process first so that you don't cause more issues as a result.
