BASICS OF LINUX FOR ORACLE APPS


Hi all, In this I will discuss you with the basic of linux that we used on daily bases. Now a days you will find linux servers every where. So let me help you understand this platform.





First I will tell you about the directory structure of Linux as below.





/ The root directory, the top-level directory in the FHS. All other directories are subdirectories of root, which is always mounted on some partition. All directories that are not mounted on a separate partition are included in the root directory


/bin Essential command line utilities. Should not be mounted separately; otherwise, it could be difficult to get to these utilities when using a rescue disk.



/boot Includes Linux startup files, including the Linux kernel. Can be small; 16MB is usually adequate for a typical modular kernel. If you use multiple kernels, such as for testing a kernel upgrade, increase the size of this partition accordingly.



/etc Most basic configuration files.



/dev Hardware and software device drivers for everything from floppy drives to terminals. Do not mount this directory on a separate partition.



/home Home directories for almost every user.



/lib Program libraries for the kernel and various command line utilities. Do not mount this directory on a separate partition.



/mnt The mount point for removable media, including floppy drives, CD-ROMs, and Zip disks.



/opt Applications such as WordPerfect or StarOffice.



/proc Currently running kernel-related processes, including device assignments such as IRQ ports, I/O addresses, and DMA channels.



/root The home directory of the root user.



/sbin System administration commands. Don't mount this directory separately.



/tmp Temporary files. By default, Red Hat Linux deletes all files in this directory periodically.



/usr Small programs accessible to all users. Includes many system administration commands and utilities.



/var Variable data, including log files and printer spools.



Now you have simple idea about structure . please wait for next post .

DBA_SCHEDULER_JOB_RUN_DETAILS and PURGE_LOG

How to purge DBA_SCHEDULER_JOB_RUN_DETAILS? Manually deleting from DBA_SCHEDULER_JOB_RUN_DETAILS is not recommended by oracle.DBA_SCHEDULER_JOB_RUN_DETAILS is a view that is using two master tables (scheduler$_job_run_details and scheduler$_event_log) and display the information about jobs history. As there is one procedure named PURGE_LOG and Oracle have Scheduler for this procedure. It will purges all rows in the job log that are older than 30 days.This is the default behavior of this procedure. You can change this to any number of days you want by setting the attribute "SET_SCHEDULER_ATTRIBUTE". e.g. exec DBMS_SCHEDULER.SET_SCHEDULER_ATTRIBUTE('log_history','15'); It will purge all logs older than 15days and it will maintain the history of 15days. But If you want manually purge these logs, you can use below solution:- exec DBMS_SCHEDULER.PURGE_LOG(log_history => 15, which_log => 'JOB_LOG'); It will purge all entries from the jog log that are o...

ORA-65016: FILE_NAME_CONVERT must be specified

ORA-65016: FILE_NAME_CONVERT must be specified I just started working on 12C version of oracle database.It's new to me and facing many problems. Error code: ORA-65016: FILE_NAME_CONVERT must be specified Description:"ORA-65016: FILE_NAME_CONVERT must be specified" normally occurs when you create a PDB.I will explain later what is a PDB. Cause and solution :  ORA-65016: FILE_NAME_CONVERT must be specified caused when Data files, and possibly other files, needed to be copied as a part of creating a pluggable database.Enable OMF or define PDB_FILE_NAME_CONVERT system parameter before issuing CREATE PLUGGABLE DATABASE statement, or specify FILE_NAME_CONVERT clause as a part of the statement and make sure the path you are giving to convert the file exists. I think if you are creating the PDB's using GUI then you will not face this error "ORA-65016: FILE_NAME_CONVERT must be specified". If you creating ODB using script and you have gave a wrong path then may you f...
