R12.1 log locations and log collection

To troubleshoot a technology stack (Web issue or Forms error),  Oracle Support asks a lot of logs, before they take a look on the service request (SR) or even they may not know what they are doing.  Recently I followed Doc ID 1942889.1 (SRDC - Data Collection Request for EBS: IAS) to collect diagnostic data/logs.

1. follow Doc ID 2026081.1 to run 5 sql scripts to generate 5 .txt files and save them to /tmp.

2. run below line to zip all needed files
$ more zip1942889_1.sh
zip -r /tmp/$TWO_TASK'_'`uname -n`_`date +%m%d%y`_Techstack_info.zip \
/tmp/apps_version_info.txt \
/tmp/fndnodes_oss.txt \
/tmp/web_urls.txt \
/tmp/atg_ver_patches.txt \
/tmp/login_profiles.txt \

$ORA_CONFIG_HOME/10.1.3/j2ee/* \
$ORA_CONFIG_HOME/10.1.3/javacache/* \
$ORA_CONFIG_HOME/10.1.3/opmn/*

3. run below line from Doc  (Doc ID 601736.1 to get techstack Component Versions (Forms, Http Server, JDK, Framework)

$ cd $FND_TOP/patch/115/bin   
$ $ADPERLPRG $FND_TOP/patch/115/bin/TXKScript.pl \

-outfile=/tmp/Report_App_Inventory.html
