By Kirtikumar Deshpande As a DBA, there will be situations when you would like to know if a particular Oracle database is up and running, and if it is accessible to end users. Most solutions involve checking for the presence of a background process such as PMON or SMON (or in older versions, the file sgadef.dbf). However, these solutions do not tell the DBA if the database is accessible or not. The following simple code does two things. It positively verifies that the listener process is working properly and the database is accessible by trying to connect to it. You do not need to set up any special user account to try to make a connection! Here's the code: #!/usr/bin/ksh # # dbcheck : Script to check if datbase is up # and accessible #----------------------------------------------- echo "Enter Name of the Database SID to check if it is accessible" read DB # Let us try to connect to the DB using a # dummy userid/password. sqlplus -s << EOF > /tmp/$$.1 whenever sqlerror exit aaa/aaa@$DB exit; EOF ## Please be sure EOF start in column 1 egrep 'ORA-121|ORA-01034' /tmp/$$.1 > /dev/null if [[ $? = 0 ]] then echo "-----> '$DB' is _NOT_ Accessiblen" else grep 'ORA-01017' /tmp/$$.1 > /dev/null if [[ $? = 0 ]] then echo "-----> '$DB' is UP and Accessiblen" else echo "-----> '$DB' is _NOT_ Accessiblen" fi fi rm /tmp/$$.1 # --- End of File FOR MORE INFORMATION: The Best Oracle Web Links: tips, tutorials, and more http://searchdatabase.techtarget.com/bestWebLinks/0,289521,sid13_tax282873,00.html Ask your technical Oracle questions--or help out your peers by answering them--in our live discussion forums: http://searchdatabase.techtarget.com/forums/0,289802,sid13_fid1,00.html Help your peers: Submit your own tip and win a Toshiba DVD player! http://searchdatabase.techtarget.com/tipsPrize/0,289492,sid13_prz520733_cts520732,00.html ================================================ SPONSORED BY: **Storage Decisions 2001** ================================================ TIME IS RUNNING OUT to qualify to attend the FREE Storage Decisions 2001 conference in Chicago September 26-28.
