利用 Oracle 和 PHP 管理分布式跟踪文件

Trace File Manager (TFM) - Using PHP and Oracle to manage your distributed trace files--------------------------------------------------------------------------------------Deployment InstructionsOracle Layer The Oracle JServer must be installed and exist in a valid state. Ensure that the directories specified in the parameters for USER_DUMP_DEST and BACKGROUND_DUMP_DEST are set up as utl_file_dir directives in the init.ora, eg utl_file_dir=myDB/oratrace/back utl_file_dir=myDB/oratrace/user Run all of the below mentioned scripts in any database whose trace files you want to view As SYS create a user account (TFMADMIN) See - tfmadmin_create.sql This account will be the repository for all of the Oracle objects used by the utility and will be responsible for retrieving information from the file system for presentation to the PHP layer. nb ! The supplied create script is for demo purposes only. You will need to specify a password and you may also want to assign alternative default and temporary tablespaces. create the external library call Windows - see extWindows.sql Linux - see extLinux.sql nb ! for unix it would be ; create or replace library systemcalls is ‘/lib/libc.so‘; / grant necessary database privileges to tfmadmin tfmAdmin_privs_and_syns.sql grant necessary java privileges to tfmadmin tfmAdmin_java_privs.sql if this fails with any spurious dbms_java errors then issue the statements manually, eg exec dbms_java.grant_permission (‘TFMADMIN‘, ‘SYS:java.io.FilePermission‘,‘your background_dump_dest‘, ‘read‘) exec dbms_java.grant_permission (‘TFMADMIN‘, ‘SYS:java.io.FilePermission‘,‘your user_dump_dest‘, ‘read‘) create a wrapper package for utl_file pk_utl_file.sql As TFMADMIN set up the tables, views and sequence tfmadmin_objects.sql create the controlling package pack_trace_file_manager.sqlJava Layer TraceFileDisplay.java you need to compile this and use loadjava to deploy it into the TFMADMIN account sample compilation & load - see javacomp.txt test the Java laye
