Sun Java Directory Server 6.2 corruption and recovery…
This has not been classified as a Sun Directory Server error, rather it led to
a method of recovery that I would like to share.
I was working on a pair of Sun Directory Servers (version 6.2)
recently, with a custom plugin. The servers would only start with a very peculiar error
logged every second in the error log (anyone know what this means?)
[18/Jan/2008:18:49:15
+0000] – INFORMATION – conn=-1 op=-1 msgId=-1 – allow_operation:
component identity is NULL
After
a day of researching the error proved futile, we decided to rebuild
from scratch. Fortunately the data appeared intact, though there were
replication errors galore! Secondly, the partner master server logged
the same error every second so that server also needed to be rebuilt.
I
followed the following steps. Note that this was a pair of Sun
Directory Servers (version 6.2) with only a few thousand objects
(development and QA environment). The steps below may not be optimal
for many replicated servers containing hundreds of thousands or
millions of users.
-
Export
the old instance to LDIF -
Create
a new instance -
Copy
the certificates and schema from the old instance to the new -
Import
the LDIF file -
Enable
replication
Assumptions
-
Sun
Java Directory Server 6.2 -
Solaris
10 -
PKG
version of Directory Server.(location of commands differs for the
ZIP version) -
The
hostname & IP address of the new and faulty Directory instances
are the same -
Two
servers in MMR (multi-master replication) -
Custom
schema in 99user.ldif
Perform
the following……………..
First Solaris
host
1.
Shutdown the faulty Directory Server
/opt/SUNWdsee/ds6/bin/dsadm
stop /var/opt/SUNWdsee/dsins1
2.Export
the data without replication information
/opt/SUNWdsee/ds6/bin/dsadm
export -Q /var/opt/SUNWdsee/dsins1 dc=company,dc=com
/export/home/CleanExport.ldif
3.
Create a new instance on port 389 since the faulty instance is not
running
/opt/SUNWdsee/ds6/bin/dsadm
create /var/opt/SUNWdsee/dsins2
4.
Copy custom schema from the faulty directory server to the new
instance
(a)
backup the new 99user.ldif
cp
/var/opt/SUNWdsee/dsins2/config/schema/99user.ldif
/var/opt/SUNWdsee/dsins2/config/schema/99user.ldif.BACKUP
(b)
copy the schema
cp
/var/opt/SUNWdsee/dsins1/config/schema/99user.ldif
/var/opt/SUNWdsee/dsins1/config/schema/
5.
Start the new instance
/opt/SUNWdsee/ds6/bin/dsadm
start /var/opt/SUNWdsee/dsins2
6.
Create the suffix
/opt/SUNWdsee/ds6/bin/dsconf
create-suffix dc=company,dc=com
7.
Import the data into the new instance
/opt/SUNWdsee/ds6/bin/dsadm
import /var/opt/SUNWdsee/dsins2 /export/home/CleanExport.ldif
dc=company,dc=com
8.
Enable replication on the new instance
/opt/SUNWdsee/ds6/bin/dsconf
enable-repl /var/opt/SUNWdsee/dsins2 -d 40404 master
dc=company,dc=com
Second
Solaris host
1.
Shutdown the faulty Directory Server
/opt/SUNWdsee/ds6/bin/dsadm stop
/var/opt/SUNWdsee/dsins1
2.Create
a new instance on port 389 since the faulty instance is not running
/opt/SUNWdsee/ds6/bin/dsadm create
/var/opt/SUNWdsee/dsins2
3.
Copy custom schema from the faulty directory server to the new
instance
(a)
backup the new 99user.ldif
cp
/var/opt/SUNWdsee/dsins2/config/schema/99user.ldif
/var/opt/SUNWdsee/dsins2/config/schema/99user.ldif.BACKUP
(b)
copy the schema
cp
/var/opt/SUNWdsee/dsins1/config/schema/99user.ldif
/var/opt/SUNWdsee/dsins1/config/schema/
4.
Create the suffix
/opt/SUNWdsee/ds6/bin/dsconf
create-suffix dc=company,dc=com
5.
Start the new instance
/opt/SUNWdsee/ds6/bin/dsadm
start /var/opt/SUNWdsee/dsins2
6.
Enable replication on the new instance
/opt/SUNWdsee/ds6/bin/dsconf
enable-repl /var/opt/SUNWdsee/dsins2 -d 50505 master
dc=company,dc=com
First Solaris
host
1.Create
replication agreement from host 1 to host 2
/opt/SUNWdsee/ds6/bin/dsconf
create-repl-agmt dc=company,dc=com secondhost:389
2.Initialize
the second Directory Server with data from the first Directory Server
/opt/SUNWdsee/ds6/bin/dsconf
init-repl-dest dc=company,dc=com secondhost:389

Humbled by those who have less, much less.
Although it has been 20+ years since I
finished high school, The English poetry I learnt, still resonates
with me and I can recall phrases and lines to this day. William
Wordsworth wrote a sonnet that I shall reproduce here, since it is,
of course, only 14 lines.
The world is too much with us; late
and soon,
Getting and spending, we lay waste our powers;
Little
we see in Nature that is ours;
We have given our hearts away, a
sordid boon!
This Sea that bares her bosom to the moon,
The
winds that will be howling at all hours,
And are up-gathered now
like sleeping flowers,
For this, for everything, we are out of
tune;
It moves us not.–Great God! I’d rather be
A Pagan
suckled in a creed outworn; (1)
So might I, standing
on this pleasant lea, (2)
Have glimpses that would
make me less forlorn;
Have sight of Proteus (3)
rising from the sea;
Or hear old Triton (4) blow his
wreathed horn.
(1)
Brought up in an outdated religion.
(2)
Meadow.
(3)
Greek sea god capable of taking many shapes.
(4)
Another sea god, often depicted as trumpeting on a shell.
For two years our family was very
fortunate to have the services of a live-in nanny who began her
employment with us a year after our son was born. A rather simple woman,
almost illiterate, and not conversant in English, I recall that when
our daughter started grade one and began to learn reading and
writing, our nanny used some of her free time to study English
reading and writing as well. I remarked to myself that a 60 and 6
year old were learning to read and write English for the first time.
Our nanny grew very fond of our younger son and loved him as if he were the
son she could not bear (her husband divorced her in their youth as they
were unable to conceive). Upon recent a visit to her home country, she
phoned us with the most unfortunate news that she was not returning to
America as she had been diagnosed with breast cancer.
With no dependents of her own, our nanny worked to
save for her and her sisters’ retirement. Her sole possessions
accompanied her in one suitcase when she went home a few weeks ago. Thus when she called to inform us of her
condition, we offered to send her few remaining possessions to her
but she refused and suggested we give them away.
As I cleaned her
room I found notes she had taken in her English language classes. In
the notebook, among other sentences, was written:
“I love children.”
“I love to cook
for the children.”
I was moved to
tears. Here we live in one of the most
sought after areas in the world. Our children attend magnificent
schools and not deprived of toys nor clothing nor extra-curricular activities. And a
woman who at age 60 is learning English for the first time, writes of her love for children that she could not bear herself. Those of us
consumed by the rat-race and materialism that American consumerism
thrusts upon us, as
Wordsworth wrote, should stop and smell the flowers…..

a useful link – searching all libraries
I am a member at two public libraries and occasionally use university libraries too.
I found this link that will search for a book across multiple public and university libraries.
The website lists libraries near you, so I am guessing it does a reverse DNS lookup and then determines your location?
Patches required to enable Solaris servers and workstations to migrate to native-ldap clients
