« on: August 28, 2023, 07:39:31 AM »

Hi guys,
Anyone does have any experience with CMOD connected to S3 and using SSE-C (S3 Server Side Encryption with Customer managed keys)?
Not sure if this is even possible, if so, please share some info on how to configure.

Thank you,

MP Server / arsload stores the same AFP Resource many times

« on: May 20, 2020, 09:22:57 AM »

Hi guys,
not sure I my understanding of treating resources is correct or not. I have AG/AP with ACIF "RESTYPE=ALL" which does separate resource from data. While resource id 2739 is correctly found as matched,

Code: [Select]

2020-05-20 17:11:33.037909: ARS4312I Loading started, 6286 bytes to process
2020-05-20 17:11:33.075577: ARS1140I Resource /tmp/KS.70636113826651.41b25594-78ca-42a4-b051-a084c1c78101.6395.2020.05.20-11.25.39.afpds.res matches the resource >2739-106-0<

and the resource found in cache is from March-9 in TSM the same resource is stored 26'679 (!) times, given that it is still the same name TSM will try to version it. With so many versions, it starts to slow down the loads as long as 222 seconds ... not talking about space used.

The resource compare is set to 50 as per default, but I don't think so this has anything to do as the resource id is still the same and the content is identical.


Am I missing something? ...or is the is kind of "old" bug, we are on 10.1.0.5 and TSM 6.3 with SSAM mode ON.

Thank you,

MP Server / AWS S3 configuration with third party S3

« on: March 04, 2020, 08:15:21 AM »

Hi guys,

anybody has an experience configuring CMOD with Amazon S3 using non-Amazon service? e.g. Dell EMC ECS with S3 protocol.

As I understand CMOD supports this by configuring the host in config/ars.s3 config file putting there something target ECS host instead of amazonaws.com.

So far so good, AWS supports two means of addressing your bucket: path style and virtual host style.
To be more specific:
path style: https://S3host.your.domain/yourBucket/yourObject
vs
virt. host: https://yourBucket.S3host.your.domain/yourObject

Here is my question:
I am under impression the CMOD supports virtual host addressing ONLY, am I right? ... or is there a way to tweak it to support path style (the old method)? I mean by some sort of "undisclosed" config parameter(s)

I've managed to get it partially working, by configuring your.domain as host (looks odd) and S3host as your Bucket, then put the real bucket name as HLD. That worked for must of cases e.g. load/unload search and retrieve (not cached), however if your folder is configured to display object location icon at first column, this produces errors in System log. Not sure what else would not work as expected, due to this twisted configuration.

Any help here or experience will be appreciated.

Thank you,

Documentation / CMOD 10.1 ODWEK compatibility

« on: November 26, 2018, 07:02:21 AM »

Hi guys,

I just would like to share my findings in compatibility of ODWEK between CMOD Server 9.5 and 10.1.

https://www-01.ibm.com/support/docview.wss?uid=swg21392275

The ODWEK (the old "core") api used for search and retrieve of documents works as  expected. However,  using the ODWEK XMLparse method of ODServer, could give you a grief.

Since this is not a true Java API method, but rather masking with system call of arsxml utility, you will get incompatibility between server and client.
Basically the ODServer.XMLparse() method is not compatible in ANY of the combinations.

ODWEK 9.5 does not work with CMOD v10.1
nor
ODWEK 10.1 does not work with CMOD v9.5

Not sure if this is a bug or just an undocumented feature

Hope this helps to someone.

z/OS Server / Re: Automatic User and Group synchronization with LDAP

« on: November 22, 2018, 04:11:23 AM »

Hi guys,
sorry to hijack this thread, can some provide me with a sample of LDAP sub-tree which would demonstrate how to setup LDAP/AD to perform LDAP sync?
Creating CMOD Gorup(s)
Creating CMOD User(s)
Binding the respective user(s) to respective Group(s)

and the corresponding ARS_LDAP parameters mostly:
ARS_LDAP_USER_FILTER
ARS_LDAP_GROUP_FILTER
ARS_LDAP_GROUP_MAPPED_ATTRIBUTE


I would appreciate your help.
Thank you,

MP Server / arssockd reload cached configuration

« on: June 05, 2018, 07:41:07 AM »

Guys, is there a way to reload (cached) configuration of arssockd on Unix without arssockd reboot? A kind of similar concept as to send a user signal to the arssockd process which will internally trigger configuration reload (such as storage set configuration for System Log etc.)?
Thx a lot,

MP Server / CMOD MP Library server with zOS Object server

« on: October 03, 2017, 06:36:35 AM »

Guys,
I must admit haven't searched the forums in deep. 
So do blame me if this was already asked / answered elsewhere.

Anyone tried to connect CMOD Library server running on Linux with CMOD Object server running on z/OS mainframe?

I need to migrate huge CMOD (20+ years of data) from zOS to Linux farm. (If you would like to ask the obvious why: a. cost, b. the CMOD had never ran any expiry and OAM is configured to Never expire, so rather than expiring 60-70% of data, I would migrate what needs to be kept and can the rest)

So, the idea is:

• connect the two  Lib & Obj on MP to  Obj on zOS (if technically doable)
• script arsadmin retr/store from z/OS to MP, idea to run both ends from Linux

Thx for ideas,
N.

MP Server / ARSXML failed to create user with UID>49774

« on: August 01, 2017, 05:31:06 AM »

Guys, anyone noticed problem with creating (adding) a new user using arsxml when the last existing uid=49774 ?

Code: [Select]

<user password="XXXXXX" name="USER1234" description="A new user" fullName="USER1234" >
Failed with Err:

ARS7709I Adding user, USER1234
ARS7743E A user object named 'USER1234' already exists.
ARS7761I Add of user, USER1234 failed.


Forcing UID<49774 by finding a number range gap:

Code: [Select]

<user password="XXXXXX" uid="1001" name="USER1234" description="A new user" fullName="USER1234" >
Have worked well.

Any idea or known limitation?

Report Indexing / PDF Indexer with separate index data

« on: June 20, 2017, 12:46:13 PM »

Hi guys,
I have PDFs previously intended to be loaded by using Generic indexer (.IND) The PDF files do not contain PPDs.

However, I would like to use resource separation, in order to increase compression ratio, to do so I (guess) have to use the PDF Indexer.

Can you advise how to merge or instruct PDF Indexer to use the index data from .IND?

Note: I was looking into arspdoci tool, however 'm not sure if this is the right way (only way or no way) to go about.

Thx a lot

Documentation / How to use the new XML Indexer

« on: February 17, 2017, 09:03:21 AM »

Hi guys, I need your help or advice about new feature in CMOD9.5 the XML Indexer.
I've tried to locate some documentation which would explain how this stuff works, but have failed to find something complete with a e2e example.
I would like to know how the XML resp XSD would map to given application/application group as how would I say which field/tag of XML goes to which AG field? Or, does it needs to be one2one ?
Attached is my sample files, xml, generated xsd and application setup. I did not attached the AG setup as I think it is clear enough.
Thanks a lot for helping

Documentation / Configuring storage node access method with HDFS

« on: November 16, 2016, 09:04:00 AM »

Hi guys, there seems to be very little information about the new feature added in 9.5.0.4 using HDFS or Swift as storage access menthod instead of TSM.
Does any one know where to find more information / docu about how to setup CMOD with HDFS ? ... Or anyone can reply with a few bullet points about the process?

Thank you,
