DBA in the Trenches

Came across this issue at a customer site or should I say my Liron ran across the issue and asked Arty and myself to investivate. He gave us the hint that it looked like XML Database was not installed. exec sys.dbms_network_acl_admin.create_acl (acl => 'test.xml', description => 'test acl', principal => 'test', is_grant => true, privilege => 'resolve') ;  PLS-00201: identifier 'DBMS_XEVENT.XDBREPOSITORYEVENT' must be declared Check which options are selected in the database select * from v$option order by value,parameter; PARAMETER                                                        VALUE ---------------------------------------------------------------- ---------- Active Data Guard                                        ...

Set the following to get a tracefile: SRW.DO_SQL ('alter session set events=''10046 trace name context forever, level 4'' tracefile_identifier=''REPORT'' '); Need to run this on the Database Tier select p.value from v$parameter p where 1=1 and p.name like 'user_dump_dest'; tkprof input.trc output.prf EXPLAIN=apps/apps SYS=NO You can know use this in a before report trigger srw.user_exit('FND SRWINIT');   srw.message(200,'XX_DEBUG_PRINT:'||fnd_profile.value('XX_DEBUG_REP'));  if (nvl(fnd_profile.value('XX_DEBUG_PRINT'),'N') = 'Y') then      SRW.DO_SQL ('alter session set events=''10046 trace name context forever, level 4'' tracefile_identifier=''REPORT'' '); end if;

I'm not a big fan of creating a db link in the tnsnames.ora file because during clones you need to start messing around with custom files. My preferred method is using a bit of SQL to create the db link. Using the details from the tnsname.ora file of the target database: TEST=  (DESCRIPTION=   (ADDRESS=(PROTOCOL=tcp)(HOST=oradbtest.company.com)(PORT=1521))  (CONNECT_DATA=   (SERVICE_NAME=TEST)   (INSTANCE_NAME=TEST)   )  ) I can now create the database link as follows: create public database link TESTDBLINK connect to apps identified by apps using '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=oradbtest.company.com)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=TEST)))'; Just remember you might want to not make it public and you may need to change user names and passwords to the target instance.

To be able to edit framework (OAF) pages in R12 you need a few profile options set either at site but more realistically at user level. The following profiles should be set as follows for your user level values: FND: Personalization Region Link Enabled Personalize Self-Service Defn Disable Self-Service Personal After setting these above you'll need to log out completely and then re-enter the instance. In some instances I've seen that you need to bounce Apache or clean out cache from browser. So check those if you don't see the option immediately. Reference: Puneet Rajkumar

I had a case where we need to clone an instance and set the date to the future to simulate a closing of an accounting period before an upgrade. Used the following to set the time the beginning of the following month on the database server. I'd set it on the application server to for consistency.  date -s "02/01/28 06:00:00"

Database Tier Because this is a cold backup of the database only need to run dbTier and it will do the rest for you. Thanks to Arty for this little jewel. cd $ORACLE_HOME/appsutil/clone/bin perl adcfgclone.pl dbTier Application Tier Run File System In R12.2 it has some check on the oraInst file. Make sure its there with the valid locations. vi /etc/oraInst.loc inventory_loc=/u03/APPLTEST/oraInventory inst_group=dba Remove the oracle inventory directory that you reference in oraInst. You could deregister or start messing around with the xml file but I found it easier to simply delete the directory. rm -rf /u03/APPLTEST/oraInventory Check which is the run file system grep s_file_edition_type /u03/APPLTEST/TEST/fs1/EBSapps/comn/clone/context/apps/TEST_erpapprod.xml grep s_file_edition_type /u03/APPLTEST/TEST/fs2/EBSapps/comn/clone/context/apps/TEST_erpapprod.xml Because this is a snapshot of PROD I have to remove some of the files that aren't required.
