Hi,

I am executing the command: "./opmnctl status" to get the status of the processes in the instance. There are totally 5 processes that are avaialble, out of which 3 are "Alive" and 2 are "Down". How can I use the IF loop to get the status and echo it??

For instance I want to run a check whether all the processes are "Alive" if yes then echo saying "OPMN is up" else "Not all OPMN processes are up"

Please help.

Thanks.

You can either just grep for the pattern you'd like not to find, in this case "Down" and test it's $? with if/then/fi to decide what to do.

Also to be more flexible you could do it like this:
There are many ways to do this of course.

Thanks for your reply....
I am actually new to working with Unix...Could you please explain in detail??
Following is how im getting the process details:

[root@SNRBBY34844 bin]# ./opmnctl status
Processes in Instance: oc4j_as1.mxb01981s001.naretail.na.com
---------------------------------+--------------------+---------+-----
ias-component | process-type |pid | status
---------------------------------+--------------------+---------+-----
ASG | ASG |N/A | Down
OC4JGroup:default_group | OC4J:IP-BO-C-I~ |21242 |Alive
OC4JGroup:default_group | OC4J:P-BO-M10 |N/A | Down
OC4JGroup:default_group | OC4Jc4j_soa |21240 | Alive
HTTP_Server | HTTP_Server |21239 | Alive

Thanks in advance. Appreciate your help...

If you post code, logs, data etc. use code-tags for better readability please.

Ok, processing the relevant part of your output:

1. Setting | as field separator
2. $NF is the last field, checking if it contains the pattern Alive
3. If so, the stuff in the curly braces is being done, ie. it increases the record counter r by +1 and the Alive counter a by 1. With the record counter we track how many rows we processed over all.
4. If it doesn't find the pattern "Alive" in the last field, it will use this line and check $NF for the pattern "Down". It increases the record counter by 1 and the Down counter d. The Down counter is not necessary but maybe for future use.
5. In the end, when all lines are processed, it checkes the variables and if the Alive counter is not equal the number of processed relevant rows/records, it will spit an error message as you can see.

All other lines that don't fit to the 2 rules $NF ~ /Alive/ or $NF ~ /Down/ are just bypassed.

I am trying to execute the set of code u have provided by putting it in a script file for e.g. "Test.sh" and when I am executing the script I get a following error:

awk: cmd. line:2: -
awk: cmd. line:2: ^ unexpected newline or end of string


Can u pls. help?? Thanks in advance...

If you are on Solaris use /usr/xpg4/bin/awk. Else you might check if you have gawk or nawk.

I just checked the code again with gawk, no problem, works flawless.
