I want to know what oracle internal process is running for the below session details.
How to check what process is being carried out by "ora_j001" ?
Please provide me query to find out the process ?
INST_ID SID SERIAL# USERNAME OSUSER MACHINE PROCESS OS Process ID VALUE STATUS LAST_CALL_ET PROGRAM
1 1303 13000 APPS orafin ARG-FIN1A-DC 3842124 3842124 224905256 ACTIVE 57661 oracle#ARG-FIN1A-DC (J001)
$ ps -ef | grep 3842124
orafin 3842124 1 0 18:24:54 - 2:02 ora_j001_FINPROD1
argora 4395248 4784358 0 10:41:08 pts/6 0:00 grep 3842124
$ hostname
ARG-FIN1A-DC
In such kind of process how to check whether what kind of oracle internal process is running ?
You have listed your SID there. This will find the current SQL being run by any SID. Tie this back to DBA_JOBS or DBA_SCHEDULER_JOBS to see job related activity.
select q.sql_text, q.piece from V$SQLTEXT_WITH_NEWLINES
where q.SQL_ID = <SID>
order by 2;

I need to run a snakemake pipeline on a DRMAA cluster with a total number of >2000 jobs. When some of the jobs have failed, I would like to receive in the end an easy readable summary report, where only the failed jobs are listed instead of the whole job summary as given in the log.
Is there a way to achieve this without parsing the log file by myself?
These are the (incomplete) cluster options:
jobs: 200
latency-wait: 5
keep-going: True
rerun-incomplete: True
restart-times: 2
I am not sure if there is another way than parsing the log file yourself, but I've done it several times with grep and I am happy with the results:
cat .snakemake/log/[TIME].snakemake.log | grep -B 3 -A 3 error
Of course you should change the TIME placeholder for whichever run you want to check.
I am currently working on making a CICD script to deploy a complex environment into another environment. We have multiple technology involved and I currently want to optimize this script because it's taking too much time to fetch information on each environment.
In the OpenShift 3.6 section, I need to get the last successful deployment for each application for a specific project. I try to find a quick way to do so, but right now I only found this solution :
oc rollout history dc -n <Project_name>
This will give me the following output
deploymentconfigs "<Application_name>"
REVISION STATUS CAUSE
1 Complete config change
2 Complete config change
3 Failed manual change
4 Running config change
deploymentconfigs "<Application_name2>"
REVISION STATUS CAUSE
18 Complete config change
19 Complete config change
20 Complete manual change
21 Failed config change
....
I then take this output and parse each line to know which is the latest revision that have the status "Complete".
In the above example, I would get this list :
<Application_name> : 2
<Application_name2> : 20
Then for each application and each revision I do :
oc rollout history dc/<Application_name> -n <Project_name> --revision=<Latest_Revision>
In the above example the Latest_Revision for Application_name is 2 which is the latest complete revision not building and not failed.
This will give me the output with the information I need which is the version of the ear and the version of the configuration that was used in the creation of the image use for this successful deployment.
But since I have multiple application, this process can take up to 2 minutes per environment.
Would anybody have a better way of fetching the information I required?
Unless I am mistaken, it looks like there are no "one liner" with the possibility to get the information on the currently running and accessible application.
Thanks
Assuming that the currently active deployment is the latest successful one, you may try the following:
oc get dc -a --no-headers | awk '{print "oc rollout history dc "$1" --revision="$2}' | . /dev/stdin
It gets a list of deployments, feeds it to awk to extract the name $1 and revision $2, then compiles your command to extract the details, finally sends it to standard input to execute. It may be frowned upon for not using xargs or the like, but I found it easier for debugging (just drop the last part and see the commands printed out).
UPDATE:
On second thoughts, you might actually like this one better:
oc get dc -a -o jsonpath='{range .items[*]}{.metadata.name}{"\n\t"}{.spec.template.spec.containers[0].env}{"\n\t"}{.spec.template.spec.containers[0].image}{"\n-------\n"}{end}'
The example output:
daily-checks
[map[name:SQL_QUERIES_DIR value:daily-checks/]]
docker-registry.default.svc:5000/ptrk-testing/daily-checks#sha256:b299434622b5f9e9958ae753b7211f1928318e57848e992bbf33a6e9ee0f6d94

You get the idea, with expressions like .spec.template.spec.containers[0].env you can reach for specific variables, labels, etc. Unfortunately the jsonpath output is not available with oc rollout history.
UPDATE 2:
You could also use post-deployment hooks to collect the data, if you can set up a listener for the hooks. Hopefully the information you need is inherited by the PODs. More info here: https://docs.openshift.com/container-platform/3.10/dev_guide/deployments/deployment_strategies.html#lifecycle-hooks
I currently look into the LXC container API. I am trying to figure out how can I make the operating system know to which container the currently running process belongs. In this way, OS can allocate resource for processes according to the container.
I am assuming your query is - Given a PID, how to find the container in which this process is running?
I will try to answer it based on my recent reading on Linux containers. Each container can be configured to start with its own user and group id mappings.
From https://linuxcontainers.org/lxc/manpages/man5/lxc.container.conf.5.html:
lxc.id_map
Four values must be provided. First a character, either 'u', or 'g', to specify whether user or group ids are being mapped. Next is
the first userid as seen in the user namespace of the container. Next
is the userid as seen on the host. Finally, a range indicating the
number of consecutive ids to map.
So, you would add something like this in config file (Ex: ~/.config/lxc/default.conf):
lxc.id_map = u 0 100000 65536
lxc.id_map = g 0 100000 65536
The above basically means that uids/gids between 0 and 65536 are mapped to numbers between 100000 and 1655356. So, a uid of 0 (root) on container will be seen as 100000 on host
For Example, inside container it will look something like this:
root#unpriv_cont:/# ps -ef
UID PID PPID C STIME TTY TIME CMD
root 1 0 0 02:18 ? 00:00:00 /sbin/init
root 157 1 0 02:18 ? 00:00:00 upstart-udev-bridge --daemon
But on host the same processes will look like this:
ps -ef | grep 100000
100000 2204 2077 0 Dec12 ? 00:00:00 /sbin/init
100000 3170 2204 0 Dec12 ? 00:00:00 upstart-udev-bridge --daemon
100000 1762 2204 0 Dec12 ? 00:00:00 /lib/systemd/systemd-udevd --daemon
Thus, you can find the container of a process by looking for its UID and relating it to the mapping defined in that container's config.
I am having a AIX 5.3 host to which we login and when needed uses pbrun tool to become root.Now the question is how do I find from command line as what user I have logged in to get this privileged/root user. If I am not wrong how do I find UID from my current EUID. Tried whoami and who am i both gives output as root.
"who am i" is coming from utmp. If utmp shows you as root then your pbrun tool must be changing it from what it was when you first logged in.
You could do:
ps l $$
which prints out a line with the PID and PPID. Take the PPID and do that again:
ps l <PPID>
The UID column is your numeric user id. If the PPID shows as 1, then pbrun did an exec rather than a folk / exec (which implies that it is a function or alias within your shell). In that case, you could revert to "last" which will show who logged in to which tty at what time.
======
Another idea. You can get the terminal the program is executing on via ps. This is called the controlling terminal. You can also get it via the "tty" command:
tty
/dev/pts/18
Now, feed that to "last" but remove the leading /dev/ part and take the first hit:
last pts/18 | head -1
myname pts/18 myhost.mydomain.com Nov 14 10:22 still logged in.
That is the last person to log into that particular terminal. Will that work?
I have a process that is kicked off by a scheduled batch file daily. I need to have error handling built in to restart the process if there is an error. All works great most days but I get a time out error once a month or so that is unavoidable. The process does not output an errorlevel to the bat file so I need to be able to parse the output file to determine if the process needs to restart.
I tried using the FOR /F function to pass the contents of line 12 as a variable to use in an IF statement but I have been unsuccessful. I can obviously skip to line 12 but then I am left dealing with the tokens of the remaining lines. Does anyone have any suggestions that I could try?

11 Time Out
12 General Time Out. The User ID and/or Password might be incorrect.
I would simply look for the error message in the output using FIND or FINDSTR. I wouldn't worry about the line number.
find "General Time Out. The User ID and/or Password might be incorrect." "yourFile.log" && (
echo Timeout occurred, you must put code here to restart
)
or
findstr /c:"General Time Out. The User ID and/or Password might be incorrect." "yourFile.log" && (
echo Timeout occurred, you must put code here to restart
)
This will test only line 12 of your file for a given string:
#echo off
for /f "skip=11 tokens=*" %%i in (your_log_filename) do (
echo %%i | find "General Time Out" >nul
goto check
)
:check
if errorlevel 1 (echo No Timeout occured!) else (echo Timeout occured)
