Nevertheless, it was GUI version of the SQL*Plus that I was using most often for ad hoc access to database. Once it is up, it falls through to the Tomcat start command.Hands down, an old “GUI” version of Oracle SQL*Plus ( sqlplusw.exe) which was available only on Windows, was always a bit awkward to use compared to a command line version of the same tool. The "tomcat_start_dev.sh" script loops round, checking to see if the DB is up. It could be combined, but this allows the "check_db.sh" script to be shared by multiple scripts. This sources the "check_db.sh" script, so it is included as if it were part of this script. Next, create a script called "tomcat_start_dev.sh" with the following contents.Įcho "DB not up yet. RETVAL=`sqlplus -silent $CONNECTION < # Environment variables necessary for Oracle Instant ClientĮxport LD_LIBRARY_PATH=/home/tomcat/scripts/instantclient_11_2 This is the script that will check if the database is up or not. This could be a full client installation, or an Oracle Instant Client installation.Ĭreate a script called "check_db.sh" will the following contents. The script requires an Oracle Client to make connections to the database. If the database is down, the script sleeps for 5 minutes, then checks again. In the following example, we check the database is up before starting a Tomcat application server. It is sometimes necessary to check the database is up before performing a task. If you are returning multiple rows of multiple columns it gets a bit messy and forces you to parse the return value. If you are returning a single value, this method works well.

UNIX and Linux (Returning values from SQL) Once again, the script can be made executable using the following command. Create a file called "/u01/backup.ksh" with the following contents. The following example shows how RMAN can use the same method. The shell script is ready to be run manually from the command line or scheduled using CRON. The shell script is made executable using the following command. Notice the "<< EOF" and "EOF" tags, indicating the start and end of the command being piped into the SQL*Plus executable. For example, save the following commands in a file called "/u01/get_emp.ksh". UNIX and Linux environments also allow the SQL*Plus and RMAN commands to be piped directly from theĬommand line. Once again, resulting shell script must be made Rman target=/ command can include a catalog= entry if a recovery catalog is used. Next create a batch file called "/u01/backup.ksh" containing the following lines. The resulting shell script can be run manually from the command line, or scheduled using CRON.įor RMAN, place the following RMAN commands in a file called "/u01/cmdfile.txt". Sqlplus /nolog following command makes the file executable for the file owner. Next, create a shell script called "/u01/get_emp.ksh" containing the following lines. The previous methods works equally well in UNIX and Linux environments. Powershell allows file redirection similar to UNIX/Linux shell scripting, so we can do something like the following for scott/tigerīACKUP DATABASE PLUS | rman target=/ UNIX and Linux (Method 1) Once again, resulting batch file can be run manually or scheduled. Next create a batch file called "C:\backup.bat" containing the following command. As an example, place the following RMAN commands in a file called "C:\cmdfile.txt". The method is very similar when using Recovery Manager (RMAN). (Start > Programs > Accessories > System Tools > Scheduled Tasks) or the AT scheduler. Sqlplus /nolog resulting batch file can be run manually, by double-clicking on it, or scheduled using the Scheduled Tasks Wizard Next, create a batch file called "C:\get_emp.bat" containing the following command. For example, save the following script in a file called "C:\emp.sql". To run a SQL script using SQL*Plus, place the SQL along with any SQL*Plus commands in a file and save it on your operating system. This article presents some basic techniques for creating Windows batch files and UNIX/Linux shell scripts that connect to SQL*Plus and RMAN. Home » Articles » Misc » Here Oracle Shell Scripting
