Seting the Database IDs

I have the feeling that a given DB ID cannot be re-used also if the database has been removed. Need clarification...

dbid -r cusdefinitions -> show DBID
dbid -d cusdefinitions -> delete DBID
setdbid 12002 cusdefinitions -> set DBID
dbid -C 12002 cusdefinitions

Traps and Tricks

Replication aware Datbase or not

Sometimes you get an error that the Database is Replication aware or not and does not match to your access

You have two options :

Hot Spot error for remote access

When a remote user (like Diego) start cusgui and he/she gets a java hotspot whatever error it might be caused by the user access rights !

A strange error for such a problem. Locally access you get a proper error message.

Do :

  dbuser -add -P <DBName>

Check whether there are open transactions

   dbtool -trans -info <DBName>

Hot Spot and Low Level Connection Error

Sometimes a user starting cus may get an JAVA Hotspot error like this :

comm/CVS> cus -f -import DMC_grat_scan_chop2_fast.txt

Then you may try on PACS1 the db2tty on that database. In case you get here a different error (Low Level connection error) you may need to restart the xinetd. DonĀ“t ask me why.

/etc/init.d/xinetd restart

If it still not work , try a second time. At least I was successful with it...

Funny enough you may get also this HotSpot error in case the license.xml file is not at the right place !!

Delivery of Databases to ESAC

Make a backup of the Database :

   vbackup -dev <name>_<version>.vbck -backup <name>

and put the backup on PACS1 /home/esac/databases

send an email to John Dowson <John.Dowson@sciops.esa.int> Larry O'Rourke <Laurence.O'Rourke@esa.int>

Offline DataFrame Generation into Database

Assumption: Database is backed up in case something goes wrong!!!!!!

* Log into PACS1 account oper

* type psetup

* Edit .pcss/props : Configure the TM ngestion process (see HCSS TM Ingestion User Manual - HERSCHEL-HCS-DOC-0231

* Start the EGSE router.

startRouter 9875

* Start dfgen

dfgen

This has the same properties as tmingest.

* Use rtaplay to retrieve telemetry packets from the database and pass them to the router

rtaplay

* Check progress

db2tty -d <database> | grep PacsDataFr

* In case of problems you may connect the TmPacketDumper to the Router and check :

Usage of 64 Bit Versant Beta Client in PCSS

You need to get the beta Version of Versant for 64Bit Linux from Tilmann Zaeschke <tzaeschk@rssd.esa.int>. Then your CLASSPATH and LD_LIBRARY_PATH need to point to the right libraries.

Onm PACS4 done in : /etc/csh.cshrc.local

Example in csh (installation of Versant 64Bit beta under :/opt/vds7020Blinux64_opt_beta1) :

# 64 Bit Versant test
setenv LD_LIBRARY_PATH /opt/vds7020Blinux64_opt_beta1/lib:${LD_LIBRARY_PATH}

setenv CLASSPATH /opt/vds7020Blinux64_opt_beta1/lib/jvi7.0.2-jdk1.4.jar:${CLASSPATH}
