Issues with Email attachments for Crontab Jobs

Hello ALL,

Last days I faced a strange issue with a shell script running as crontab job.

I had a Shell Script with working properly when executing manually, it functions simply sent an email with embedded attachments.  However, when it scheduled in Crontab, it does not send attachments ( I received the email but with BLANK attachments – even if code running fine and sending attachments when executed manually).

It made my brain burn for some time, then I found a lot of people facing the same issue when scripts in crontab.

It looks for some crontab relation with SH/Bash scripts.

Here are the workarounds I found and deployed in my script. Now, the email attachments are being included in emails when running as crontab jobs.

  • Include: ‘#!/bin/sh’ or ‘#!/bin/bash’ in the first line of your shell script.
  • Insert full path of commands you using in statements. E.g: Are you using ‘mailx’? so, execute ‘whereis mailx’, then, all statements where mailx is running will be like ‘/usb/bin/mailx -s “SUBJECT” myemail@domain.com’.
  • Source your sh/bash profile before the email statement. This statement solved my error. I found some posts explanations, but not sure why
    • ‘. ~/.bash_profile’.

Here is my code:

#!/bin/sh
################################################################################
# Email alerting to
################################################################################
EMAILTO="youremail@company.com"      # The email to send the alert to
SUBJECT="My shell script in crontab" # email subject

. ~/.bash_profile

sqlplus /nolog < /dev/null 2>&1
connect / as sysdba
spool /tmp/temp_out.txt
select * from dual
spool off
EOF

cat /tmp/temp_out.txt |grep "no rows selected"
if [ $? == 0 ]; then
echo "Nothing to do"
/usr/bin/echo "Nothing to do"| /usr/bin/mail -s "${SUBJECT}" ${EMAILTO}
else
/usr/bin/cat /tmp/temp_out.txt | /usr/bin/mail -s "${SUBJECT}" ${EMAILTO}
fi
rm /tmp/temp_out.txt

Checking Basic Licensing Info on a DB Server

 , ,

Hi all!
So, I got a new client and started checking on his licensing and hardware. Then I realized how “non-standard” this is and Oracle should probably provide a better way to do it. So I decided to share a few things:

# Checking Oracle Version Installed:

[oracle@greporaSRV inventory]$ cd /opt/oraInventory/logs
[oracle@greporaSRV logs]$  grep "\- Database edition" installActions*.log
INFO: - Database edition : Standard Edition One (Create and configure a database)

# Checking number of Sockets

[root@greporaSRV ~]# cat /proc/cpuinfo | grep "physical id" | sort -u | wc -l
1

# Checking number of CPU Cores per Socket

[root@greporaSRV ~]# lscpu | grep 'socket'
Core(s) per socket:    4

Parallel file transfer on Linux

Hi all,

I had a request to copy a ton of files from one file system to another,  I know that there are tools that can help with that like rsync but due to some requirements and me wanted to do some scripting I put something together  to help with this request. This is not the 1st time I do something like this but it is the 1st time I share 🙂

What I’m sharing is now what I did for the request I mentioned but you will get an idea

The script will copy a list of files from one server to another. This list I usually create by using find like this

find /Directory_which_I_want_to_copy -type f > file_list.txt

The script will receive some parameters as listed below

parallel_xfer.ksh

Also a requirement for this to work is that you can ssh to the target server without a password.

It will keep X parallel sessions running at all times until there are new files to start copying it, After all copies are started, it will monitor them until completion. Also the script assumes that the source and target directory destination is the same but this is easily changed if needed.

The logging needs to be improved but it will show the file it started as well their processes count

Hope it helps

Automatic Graceful Shutdown and Consistent Startup Method for Oracle DB on Linux

 , ,

Hi all,

This is quite a common question whenever I arrive on any new company. The things is, there are more then one way to implement this depending on your environment, licensing and version.

So I decided to compile here some sort of summary for this:

1. Prefer to use Oracle Restart
This is the automated and validated method provided by Oracle, however it can be a bit confusing in some items which can lead us to think it’s not working. Here is a summary of the the configuration I recommend:

a) Configure database management to AUTOMATIC on SRVCTL

srvctl modify database -y AUTOMATIC
  • If AUTOMATIC (the default), the database is automatically restored to its previous running condition (started or stopped) upon restart of the database host computer.
  • If MANUAL, the database is never automatically restarted upon restart of the database host computer.

Ref: https://docs.oracle.com/cd/E11882_01/server.112/e25494/restart.htm#BABHHAHI

b) Set AUTO_START=always on CRSCTL

crsctl modify resource ora.grepora.db -attr AUTO_START=always
  • ALWAYS: Restarts the resource when the server restarts regardless of the state of the resource when the server stopped.
  • RESTORE: Restores the resource to the same state that it was in when the server stopped. Oracle Clusterware attempts to restart the resource if the value of TARGET was ONLINE before the server stopped.
  • NEVER: Oracle Clusterware never restarts the resource regardless of the state of the resource when the server stopped.

NOTE: On Oracle 11.2, the database auto start policy in the clusterware is restore, which means that clusterware will remember the last state of the database. As well as database, Oracle 11.2 comes by default with several important resources with attribute AUTO_START=restore in the profile.

NOTE2: 12c on you might need to use the flag “-unsupported” on command above (crsctl modify resource ora.grepora.db -attr AUTO_START=always – unsupported).

Ref: https://docs.oracle.com/cd/E11882_01/rac.112/e41959/resatt.htm#CHDFFEHJ

Observation: This is recommended for all the required components managed by those tools, like databases, asm, listener, diskgroups, etc.
I wrote an article about it with an script that I made by my own and can help you: https://grepora.com/2018/08/22/services-not-starting-automatically-with-crs-after-reboot/

A common problem: “I set the SRVCTL to Automatic, but databases still not starting automatically’.”
Explanation: When database Management policy is configured as AUTOMATIC and the resource of the database parameter AUTO_START is configured as restore, the cluster will restore its last state, because the cluster level is the first in the chain of commands, it overrides the database.

c) Save desired state of Pluggable Databases in case of Multitenant:
With the PDB in desired state, save it with command below:

ALTER PLUGGABLE DATABASE pdb1 SAVE STATE;

When the CDB start, it will bring the pdbs to it saved states.

2. As second Option, Oracle Provided Scripts

Oracle has some scripts to automate it in a standard and supported way. This is documented for 12.1 in Stopping and Starting Oracle Software.

NOTES:

  • Oracle 11gR2 documentation states the use of the dbstart and dbshut scripts are deprecated. It’s supposed to be replaced by Oracle Restart.
  • The Oracle 12c documentation has no mention of the deprecation of dbstart and dbshut and has reinstated the documentation about them (as I linked above). So, feel free to use dbstart and dbshut in a supported manner for all versions of the database.

I also wrote an article about those, with some info and scripts: https://grepora.com/2017/11/22/how-to-setup-automatic-startup-and-shutdown-of-an-oracle-database-on-linux-not-using-oracle-restart/

Observation: Item 1.c is still recommended here.

3. Community proven scripts

As a third option, we would have some community scripts, which are usually proven and doesn’t require us to remember or to code everything. I’d use some additional time reviewing and testing them though, as they are not Oracle provided/supported.

In general, I’d recommend the material produced by Tim Hall (Oracle Base): https://oracle-base.com/articles/linux/automating-database-startup-and-shutdown-on-linux

He has additional articles that may help for other versions:

  • Automating Shutdown and Startup (12.2)
  • Automating Shutdown and Startup (12.1)
  • Automating Shutdown and Startup (11.2)
  • Automating Shutdown and Startup (10.2)
  • Automating Startup and Shutdown (10.1)
  • Automating Database Startup and Shutdown (9.2)
  • Linux Services (systemd, systemctl)

 

Some Additional Twists:

  • The Oracle Restart configuration assume the CRS is left “enabled”. Disabling it means we don’t want it to start automatically. So, if you want the CRS to start with your server, it need to be enabled. After this, to start targets, depend on configurations as per mentioned on my previous post.
  •  Oracle will no execute any rpm change or relink automatically, as this is not part of any “restart” process. It may be required due any configuration change or corruption, and it cannot be automated.
  • Regarding gracefulness, it depends on the configuration you have on your SRVCTL too. It’s configured using stop and start option, as per example below:
srvctl modify database -d [db_unique_name] -s [start_options] -t [stop_options]
  • So for your case, it seems to me a complete command containing what was recommended on my previous post PLUS gracefulness, it would be:
srvctl modify database -d [db_unique_name] -s OPEN -t IMMEDIATE -y automatic

(Note the SRVCTL syntax can very on the versions. This one is valid for 11.2).

I hope this helps you on understanding the process.

See you next time!

Getting Oracle version – new utility on 18c oraversion

While scripting on an environment with different Oracle versions, I often needed to get the Oracle version for the target database as usually the SQL to be executed is version depended.

I used different methods to grab the database  version some you can see below:

SQL> select 
substr(
substr(
banner, 
instr(banner,' ',-(length(banner)-instr(banner,'.')),1)+1, 
instr(banner,' ',+instr(banner,'.'),1)-instr(banner,' ',-(length(banner)-instr(banner,'.')),1)-1
),
1, 
instr(
substr(
banner, 
instr(banner,' ',-(length(banner)-instr(banner,'.')),1)+1,
instr(banner,' ',+instr(banner,'.'),1)-instr(banner,' ',-(length(banner)-instr(banner,'.')),1)-1
),
'.'
)-1
) version
from v$version
where rownum = 1
; 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

VERSION
--------------------------------------------------------------------------------
18

Or like this

SQL> select substr(version,1,instr(version,'.')-1) version from product_component_version where product like 'Oracle%';

VERSION
--------------------------------------------------------------------------------
18

But on Oracle 18c there is a new utility called oraversion which you can get the same result as the above queries.

[oracle@server01 ~]$ oraversion
This program prints release version information.
These are its possible arguments:
-compositeVersion: Print the full version number: a.b.c.d.e.
-baseVersion: Print the base version number: a.0.0.0.0.
-majorVersion: Print the major version number: a.
-buildStamp: Print the date/time associated with the build.
-buildDescription: Print a description of the build.
-help: Print this message.
[oracle@server1 ~]$

[oracle@server01 ~]$ oraversion -majorVersion
18
[oracle@server01 ~]$

This could be somewhat useful but I though it was worth sharing.

Until next time.

Oracle memory usage on Linux / Unix

 , ,

Hi all,

So one of the most important things that we need to do when setting up a new server or checking the capacity of the server is to see how much memory Oracle is using.

When checking the capacity there are some practical things that always help me to get a fast glimpse of the system:

  • When opening topas and hitting M you will see this below
Topas Monitor for host: SERVER1 Interval: 2 Sat Dec 8 03:39:59 2019
================================================================================
REF1 SRAD TOTALMEM INUSE FREE FILECACHE HOMETHRDS CPUS
--------------------------------------------------------------------------------
0 0 59.8G 59.6G 212.3 16.3G 528 0-15
1 1 61.4G 61.2G 188.8 15.7G 536 16-31

On the memory session you will see 3 categories, INUSE, FREE and FILECACHE. There you may see what is being using for what but there is not much granularity there.

  • When using top you have this summary below
top - 11:48:08 up 119 days, 10:18, 1 user, load average: 26.76, 26.16, 25.95
Tasks: 1936 total, 38 running, 1898 sleeping, 0 stopped, 0 zombie

Swap: 16773116k total, 505760k used, 16267356k free, 88055108k cached

Same you have a high level usage. So here comes the question:

How are you to prove that you have a memory shortage?

I often use vmstat on Linux looking on the columns si and so equals to 0 (swap in and swap out) and when the free command, the free column you will also have no or very low swap being used

Swap: 16773116 505760 16267356

To check a process specific memory usage (RSS) I often use ps along with other commands to calculate the process memory for a specific process id as below:

/home/oracle> ps -eo rss,pid,euser,lstart,args:100 --sort %mem | grep -v grep | grep 35796 | awk '{printf $1/1024 "MB"; $1=""; print }'| sort
19.6016MB 35796 oracle Sat Sep 8 02:43:54 2018 ora_lg00_ORC1
34.957MB 32340 oracle Sat Jan 5 11:50:09 2019 oracleORC1 (LOCAL=NO)

RSS is resident memory, but when comes to shared memory like the Oracle SGA the methods above could be miss leading – not to say wrong – but as Oracle memory is shared we may see double counting on the results. I sometimes use pmap to check a process memory as well when available

/home/oracle> pmap 35796
35796: ora_lg00_ORC1
total 0K

But, still when checking a server wide scope, do you want to keep doing manual work and lots of math? I don’t think so. 🙂

That’s why when I came across SMEM made my life a lot easier. It is a python script which gives you a nice breakdown of the memory usage and without the miss leading double counting.

You can see the commands and processes and their memory:

MySQL: Sed for Scripts using “Show” from Command Line

 , ,

Hi all,
So, a pretty basics one today… But useful to have handy. How to script an output from  mysql -B -e?

Easy, by using SED. Ok, by replacements are always tricky considering the line braking and etc. So, here goes an example with show tables:

Original Output.

[root@greporasrv ~]# mysql sbtest -B -e 'show tables'
Tables_in_sbtest
sbtest1
sbtest10
sbtest2
sbtest3
sbtest4
sbtest5
sbtest6
sbtest7
sbtest8
sbtest9
Cool, now with all in one line:
[root@greporasrv ~]# mysql sbtest -B -e 'show tables'|sed ':a;N;$!ba;s/\n/ /g'
Tables_in_sbtest sbtest1 sbtest10 sbtest2 sbtest3 sbtest4 sbtest5 sbtest6 sbtest7 sbtest8 sbtest9

Great, so let’s put some useful code on it:

[root@greporasrv ~]# mysql sbtest -B -e 'show tables'|sed ':a;N;$!ba;s/\n/ engine=innodb; \n alter table /g'
Tables_in_sbtest engine=innodb;
alter table sbtest1 engine=innodb;
alter table sbtest10 engine=innodb;
alter table sbtest2 engine=innodb;
alter table sbtest3 engine=innodb;
alter table sbtest4 engine=innodb;
alter table sbtest5 engine=innodb;
alter table sbtest6 engine=innodb;
alter table sbtest7 engine=innodb;
alter table sbtest8 engine=innodb;
alter table sbtest9 engine=innodb;

Hope you can use for your needs.

Cheers!

Amazon EC2: X11 Forwarding After Sudo SSH Session

 , , , , ,

Hello all!

So, now with more use of resources like Cloud servers, more and more silent instalations are being done, right? Myself, I do it in silent always I can.

What if I need to export X. Plus, if I need to export it from user oracle, but I can only login with ec2-user, as usual?

Here is the process for that:

1) Connect to AWS EC2 instance

[user@securehost ~]$ ssh -X ec2-user@ipaddress
Last login: Fri Dec 7 14:41:41 2018 from grepora.srv.com
__| __|_ )
 _| ( / Amazon Linux AMI
 ___|\___|___|
https://aws.amazon.com/amazon-linux-ami/2018.03-release-notes/
13 package(s) needed for security, out of 16 available
Run "sudo yum update" to apply all updates.

2) Test xclock works from ec2-user

[ec2-user@ipaddress ~]$ xclock
Warning: Missing charsets in String to FontSet conversion
^C

3) Show all magic cookie

[ec2-user@ipaddress ~]$ xauth list
ipaddress/unix:12 MIT-MAGIC-COOKIE-1 7e53e7600ff4177d7bbc66bde0a1b1ca
ipaddress/unix:11 MIT-MAGIC-COOKIE-1 e3d1a8915484c929ef3e809b047e6352
ipaddress/unix:10 MIT-MAGIC-COOKIE-1 07b3de3093cef835c19239ea952231b7

4) Show DISPLAY variable

[ec2-user@ipaddress ~]$ env|grep DISPLAY
DISPLAY=localhost:10.0

5) Create /tmp/xauth based on current DISPLAY variable

[ec2-user@ipaddress ~]$ xauth list | grep unix`echo $DISPLAY | cut -c10-12` > /tmp/xauth
[ec2-user@ipaddress ~]$ ll /tmp/xauth ; cat /tmp/xauth

ipaddress/unix:10 MIT-MAGIC-COOKIE-1 07b3de3093cef835c19239ea952231b7

6) Sudo to oracle

[ec2-user@ipaddress ~]$ sudo su - oracle
Last login: Fri Dec 7 14:43:12 UTC 2018 on pts/0

7) Add and Verify xauth

[oracle@ipaddress ~]$ xauth add `cat /tmp/xauth`
[oracle@ipaddress ~]$ xauth list
ipaddress/unix:10 MIT-MAGIC-COOKIE-1 07b3de3093cef835c19239ea952231b7

8) Verify and Add DISPLAY variable

[oracle@ipaddress ~]$ env|grep DISPLAY
[oracle@ipaddress ~]$ export DISPLAY=localhost:10.0

9) Test xclock works from oracle

[oracle@ipaddress ~]$ xclock
Warning: Missing charsets in String to FontSet conversion
^C
[oracle@ipaddress ~]$

Now you should be able to see the clock and so other graphical resources, like DBCA and so on.

Hope it helps!

Database, Shell Scripts

Managing listener.log and log.xml with Linux Logrotate

 , , ,

Hi all,
To manage Oracle trace files the way to go is ADRCI. You can see this post from Matheus if you have not read it yet.

In the last part of the script we have a small bash code to configure the ADRCI on all databases running on a server

You could add:

adrci exec="set home $1;purge -age 10080 -type ALERT";

In this case the age parameter is in minutes but still you would be required to run it periodically which could be another script in crontab to be managed.

SO the solution that I found to be best as it takes leverage from an existing solution is called logrotate.

Logrotate is a Unix/Linix based program that helps as its name says, rotate any file that you need. You just need to create a configuration file and place it on /etc/logrotate.d on most Linuxes distributions.

But when you have a server with several databases and listerners and more, it starts to get a bit tedious and time consuming to create this manually.

In this post on the Pythian Blog, will find how to create but it does not handle the listener.log nor the log.xml so I added this piece here

for L in `\ps -ef | grep tnslsnr | grep -v grep | sed s'/-.*$//g' | awk '{print $NF}'`
do
OUT=${DEST}/"logrotate_xml_"${L}
LSRN_LOG=`lsnrctl status ${L} | grep "Listener Log File" | awk '{print $NF}'`
echo ${LSRN_LOG%.*}"*" " {" > ${OUT}
cat << ! >> ${OUT}
daily
rotate 1
compress
notifempty
}
!
echo ${OUT} has been generated
done

for L in `\ps -ef | grep tnslsnr | grep -v grep | sed s'/-.*$//g' | awk '{print $NF}'`
do
	OUT=${DEST}/"logrotate_xml_"${L}
	LSRN_LOG=`lsnrctl status ${L} | grep "Listener Log File" | awk '{print $NF}'`
	echo ${LSRN_LOG%.*}"*.xml" " {"		>  ${OUT}
	cat << !			>> ${OUT}
	daily
	rotate 1
	compress
}
!
	echo ${OUT} has been generated
done

Using logroate really helps on the managing on Oracle related files which are not done by ADRCI.

Hope it helps,

ASM, Shell Scripts

Even Better Script: Map ASM Disks to Physical Devices

 , ,

Enjoyed last week post?

Cool, because looking further on the subject I found this pretty similar post, by Mohammad Nazmul Huda.

The additional script there is actually not working in my server, but the idea is great. So, I did just some small adjustments and it’s working pretty fine now:

# asm_report.sh (Adjusted by Matheus):

printf "\n%-15s %-14s %-11s %-7s\n" "ASM disk" "based on" "Minor,Major" "Size (MB)"
printf "%-15s %-14s %-11s %-7s\n" "===============" "=============" "===========" "========="
export ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/dbhome1
for i in `/usr/sbin/oracleasm listdisks`
do
v_asmdisk=`/usr/sbin/oracleasm querydisk -d $i | awk '{print $2}'| sed 's/\"//g'`
v_minor=`/usr/sbin/oracleasm querydisk -d $i | awk -F[ '{print $2}'| awk -F] '{print $1}' | awk -F, '{print $1}'`
v_major=`/usr/sbin/oracleasm querydisk -d $i | awk -F[ '{print $2}'| awk -F] '{print $1}' | awk -F, '{print $2}'`
v_device=`ls -la /dev | awk -v v_minor="$v_minor," -v v_major=$v_major '{if ( $5==v_minor ) { if ( $6==v_major ) { print $10}}}'`
v_size_bt=`blockdev --getsize64 /dev/${v_device}`
v_size=`expr $v_size_bt / 1024 / 1024`
Total_size=`expr $Total_size + $v_size`
Formated_size=`echo $v_size | sed -e :a -e 's/\(.*[0-9]\)\([0-9]\{3\}\)/\1,\2/;ta'`
printf "%-15s %-14s %-11s %-7s\n" $v_asmdisk "/dev/$v_device" "[$v_minor $v_major]" $Formated_size
done
Formated_Total_size=`echo $Total_size | sed -e :a -e 's/\(.*[0-9]\)\([0-9]\{3\}\)/\1,\2/;ta'`
printf "\nTotal (MB): %43s\n\n" $Formated_Total_size

Ok, and how it works?
[root@greporasrv ~]# sh asm_report.sh

ASM disk        based on      Minor,Major Size (MB)
=============== ============= =========== =========
DATA01          /dev/sdg1     [8 97]       255,999
DATA02          /dev/sdh1     [8 113]      255,999
DATA03          /dev/sdi1     [8 129]      255,999
DATA04          /dev/sdj1     [8 145]      255,999
FRA01           /dev/sdk1     [8 161]      307,199

Total (MB): 1,331,195

Even better, right?

Cheers!
