Rsync DBFS To ACFS For GoldenGate Trail Migration

Filed under: GoldenGate,shell scripting — mdinh @ 2:25 pm

Planning to move GoldenGate trail files from DBFS to ACFS.

This is pre-work before actual migration to stress IO for ACFS.

Learned some cron along the way.

# Run every 2 hours at even hours
0 */2 * * * /home/oracle/working/dinh/acfs_ggdata02_rsync.sh > /tmp/rsync_acfs_ggdata_to_ggdata02.log 2>&1

# Run every 2 hours at odd hours
0 1-23/2 * * * /home/oracle/working/dinh/acfs_ggdata02_rsync.sh > /tmp/rsync_acfs_ggdata_to_ggdata02.log 2>&1

Syntax and ouptput.

Source Oracle Environment Easily

Filed under: oracle,shell scripting — mdinh @ 3:50 am

I have been patching a lot lately and wanted a fast and easy method to source Oracle environment.

The objective is to copy, paste from action plan vs having to selectively copy, edit, paste.

Example: . /media/patch/gi.env vs . oraenv — +ASM[n]

Started by creating gi.env which will be used to source GI for all RAC hosts.

You are probably thinking, isn’t it a PITA to have to edit and maintain all the gi.env per host, e.g. 6 nodes RAC cluster?

Rightfully so and it’s a PITA unless it’s dynamic.

There is one requirement: host# = instance#

Hence, +ASM1 is running on host05 will not work.

Next step would probably be to script the tasks.

DEMO1:

RMAN 12c NF – SQL interface in RMAN 

Filed under: 12c,RMAN,shell scripting — mdinh @ 11:51 pm

Admittedly, I did not realize the benefit at first until there came a need.

Example:


# Set ORACLE_SID
ORACLE_SID=$1
export ORACLE_SID
### This retrieve the numeric value from PROD1/PROD2, i.e. 1,2 respectively
n=`echo "${ORACLE_SID:(-1)}"`

run {
backup tag 'ARCHIVED_LOG' archivelog all delete input skip inaccessible;
alter database backup controlfile to trace as '/rman_bkup$n/$ORACLE_SID/cf_@.sql' REUSE RESETLOGS;
create pfile='/rman_bkup$n/$ORACLE_SID/init@.ora' from spfile;
create pfile from spfile;
}

Automating DG Broker

Filed under: 11g,awk_sed_grep,Dataguard,oracle,shell scripting — mdinh @ 2:11 am

I have been applying PSU lately and what’s so hard out it?

Four+ databases running on Primary with DG Broker for standby.

There are no conventions, as some standby databases have dr appended to primary name while others have 2 appended to primary name.

I wanted to view the DG configuration for currently active instances and show_dg_config.sh will show me this.

Next, I want a faster way to shutdown DG by having syntax generated and gen_dg_cmd.sh does this.

Guess I could have taken it further by creating a shell script to create shell scripts to shutdown DG.

One day when I am really bore, I might OR may be you are so nice to complete my mission.

Tested on AIX 7.1

Note: the ps -ef syntax is for AIX and will not work with Linux.

See below for the Linux alternative.

$ ps -ef -o args|grep ora_smon|grep -v grep|awk -F"_smon_" '{print $2}'
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQ

Using dynamic variables for shell scripting

Filed under: linux,oracle,shell scripting — mdinh @ 7:21 pm

So you may ask, why go through all the trouble?

Have you ever had to move scripts from one directory to another to find out the script is now broken?

This is due to the hard coding of the location for SQL script in the shell script.

When possible, I would like to separate shell / SQL scripts so they can be run individually and easier for debugging.

Don’t you hate it when copy/paste SQL from shell and require modifications?

Example: SELECT count(*) FROM v\$transaction t, v\$session s WHERE t.addr=s.taddr

When the shell & SQL scripts have the same name, it’s more intuitive, as well as the log file.

Example: open_trans.sh, open_trans.sql, /tmp/open_trans_hawklas.log

You can find example of shell scripts with all comments open_trans.sh

DEMO:

oracle@arrow:hawklas:/media/sf_working/scripts
$ ./open_trans.sh

Not enough variables passed to shell script.

Shell script – checking for NULL & RMAN backup

Filed under: 11g,RMAN,shell scripting,solaris — mdinh @ 2:13 pm

The existing backup strategy for archivelog is Disk-to-Disk-to-Tape (D2D2T), using RMAN for disk and NetBackup for tape.

Delete existing backup after successfully back up to tape.

Don’t know enough about NetBackup or whether it can do the deletion, and that’s a story for another day.

Here is the scenario: the file exist but contains NULL data, will the RMAN backup be deleted?

File exists:

> ll /home/oracle/check_backup/check_bkup.out
-rw-r--r--   1 mdinh    dba            0 Dec 15 13:15 /home/oracle/check_backup/check_bkup.out

NULL data: the file is ZERO byte.

Script:

> cat t.sh
#!/bin/sh

DN=`dirname $0`
BN=`basename $0`
SID=${1:?"---> USAGE: $DN/$BN <ORACLE_SID>"}

date
FILE=/home/oracle/check_backup/check_bkup.out
LAST=`head /home/oracle/check_backup/check_bkup.out |grep Archive|head -1|awk '{print $1}'`
# Check for ora_smon process
if [ `pgrep -lf ora_smon_$1|awk -F_ '{print $3}'` != $1 ]; then
exit 1
elif [ `pgrep -lf "$BN $1"|wc -l` -gt 2 ]; then
exit 1
elif [ ! -f $FILE ]; then
mailx -s "Missing $FILE" maile@me.com < /dev/null
exit 1
fi

echo ---------- NO NULL check ----------
echo "delete noprompt backup completed before \"to_date('${LAST}','mm/dd/yyyy')\";"

# if $LAST IS NOT NULL
if [ ! -z "$LAST" ]; then
echo "delete noprompt backup completed before \"to_date('${LAST}','mm/dd/yyyy')\";"
fi
exit

Execution:

> ./t.sh db01
Tue Dec 18 05:31:20 PST 2012
---------- NO NULL check ----------
delete noprompt backup completed before "to_date('','mm/dd/yyyy')";

Curiosity: What will happen when delete noprompt backup is executed? Any guess?

RMAN> list backup;
using target database control file instead of recovery catalog
specification does not match any backup in the repository

Shell and SQL Script

Filed under: oracle,shell scripting — mdinh @ 10:36 pm

A quick note on separating SQL from shell script.

If I have a shell script name longops.sh, then it will call longops.sql.

Don’t embed SQL in shell script so that SQL script can be executed independently.

> cat longops.sh
#!/bin/sh
. /home/oracle/.common.conf > /dev/null
DN=`dirname $0`
BN=`basename $0`

sql=`echo $BN|cut -d'.' -f1`.sql
for sid in `ps -eo args|grep ora_smon|grep -v grep|awk -F_ '{print $3}'`
do
  OUTF=/tmp/longops.${sid}.html
  rm -f $OUTF
  ORACLE_SID=$sid
  . oraenv
  $ORACLE_HOME/bin/sqlplus -SL > /dev/null / << END
    spool $OUTF
    prompt From: oracle@mail.com
    prompt To: dba@mail.com
    prompt Subject: WARNING ${BN}: $ORACLE_SID - SQL running over one hour
    prompt Content-type: text/html
    prompt MIME-Version: 1.0
    set markup html on entmap off table 'BORDER="2"'
    @${sql}
    spool off
    exit
END
  if [ "$?" -ne "0" ]; then
    mailx -s "FAILED: $BN $*" $EMAIL < /dev/null
  exit 1
  fi
  if [ `grep -ic MACHINE $OUTF` != 0 ]; then
    /usr/sbin/sendmail -t < $OUTF
  fi
done
exit


> cat longops.sql
ALTER SESSION SET NLS_DATE_FORMAT='Dy, DD-Mon-YYYY HH24:MI:SS';
SELECT s.sid, s.serial#,
       s.username,  s.osuser, s.machine, s.program,
       s.sql_id, s.sql_exec_start, s.logon_time,
       ROUND (s.last_call_et/3600,3) last_call_hr,
       ROUND ((SYSDATE-s.SQL_EXEC_START)*24,3) exec_start_hr,
       CASE WHEN s.state != 'WAITING' THEN 'WORKING' ELSE 'WAITING' END AS state,
       CASE WHEN s.state != 'WAITING' THEN 'On CPU / runqueue' ELSE event END AS sw_event
FROM   v$session s
WHERE  s.type = 'USER' AND s.status = 'ACTIVE' AND ROUND (s.last_call_et/3600)>1
ORDER BY s.last_call_et DESC;
