I am looking to understand how the functionality for searching a vendor device for sqluvint with action=SQLUV_QUERY_LOGS and db2VendorGetNextObj in the IBM DB2 vendorlib library should be implemented as part of the backup and restore functionality.
There is very minimal documentation on the input/response expectations available at https://www.ibm.com/docs/en/db2/11.1?topic=products-db2-call-sequence-vendor-apis and the sample code at https://github.com/IBM/db2-samples/blob/master/BARVendor/vendor.C does not provide any sample implementation for this.
Thanks in advance!!
Output of db2level:

I am trying to restore encrypted DB to non-encryped DB. I made changes by setting piDbEncOpts to SQL_ENCRYPT_DB_NO but still restore is being failed. Is there db2 sample code is there where I can check how to set "NO Encrypt" option in DB2. I am adding with below code snippet.
db2RestoreStruct->piDbEncOpts->encryptDb = SQL_ENCRYPT_DB_NO
The 'C' API named db2Restore will restore an encrypted-image to a unencrypted database , when used correctly.
You can use a modified version of IBM's samples files: dbrestore.sqc and related files, to see how to do it.
Depending on your 'C' compiler version and settings you might get a lot of warnings from IBM's code, because IBM does not appear to maintain the code of their samples as the years pass. However, you do not need to run IBM's sample code, you can study it to understand how to fix your own C code.
If installed, the samples component must match your Db2-server version+fixpack , and you must use the C include files that come with your Db2-server version+fixpack to get the relevant definitions.
The modifications to IBM's samples code include:
When using the db2Restore API ensure its first argument has a value that is compatible with your server Db2-version-and-fixpack to access the required functionality. If you specify the wrong version number for the first argument, for example a version of Db2 that did not support this functionality, then the API will fail. For example, on my Db2-LUW v11.1.4.6, I used the predefined db2Version1113 , like this:
db2Restore(db2Version1113, &restoreStruct, &sqlca);
When setting the restore iOptions field: enable the flag DB2RESTORE_NOENCRYPT, for example, in IBM's example, include the additional flag: restoreStruct.iOptions = DB2RESTORE_OFFLINE | DB2RESTORE_DB | DB2RESTORE_NODATALINK | DB2RESTORE_NOROLLFWD | DB2RESTORE_NOENCRYPT;
Ensure the restoredDbAlias differs from the encrypted-backup alias name.
I tested with Db2 v11.1.4.6 (db2Version1113 in the API) with gcc 9.3.
I also tested with Db2 v11.5 (db2Version11500 in the API) with gcc 9.3.
After Changing to version 1.19, but using Omnipath implementation, I'm randomly receiving the following error: ERROR calling: gasnet_barrier_try(id, 0).
I know that the Omnipath implementation of GASNet is no longer supported by the current version of Chapel. However, I would like to use some features available only in version 1.19, and the cluster I use runs over an Omnipath network.
In order to use the PSM substrate (OmniPath), I proceed as suggested by Chapel's Gitter community:
export CHPL_GASNET_ALLOW_BAD_SUBSTRATE=true
wget https://gasnet.lbl.gov/download/GASNet-1.32.0.tar.gz
tar xzf GASNet-1.32.0.tar.gz
rm -rf $CHPL_HOME/third-party/gasnet/gasnet-src
mv GASNet-1.32.0 $CHPL_HOME/third-party/gasnet/gasnet-src
Then, I setup other variables:
export CHPL_COMM='gasnet'
export CHPL_LAUNCHER='gasnetrun_psm'
export CHPL_COMM_SUBSTRATE='psm'
export CHPL_GASNET_SEGMENT='everything'
export CHPL_TARGET_CPU='native'
export GASNET_PSM_SPAWNER='ssh'
export HFI_NO_CPUAFFINITY=1
Next, I build the runtime, etc.
However, when I run experiments, I randomly receive the following error:
ERROR calling: gasnet_barrier_try(id, 0)
at: comm-gasnet.c:1020
error: GASNET_ERR_BARRIER_MISMATCH (Barrier id's mismatched)
Which finishes the execution of the program.
I cannot find in GASNet documentation the reason for this error. I could only find a bit of information on GASNet's code.
Do you know what's the cause of this problem?
Thank you all.
I realize this is an old question, but for the record the current version of Chapel (1.28.0) now embeds a version of GASNet (GASNet-EX 2022.3.0 as of this writing) that provides CHPL_COMM=gasnet CHPL_COMM_SUBSTRATE=ofi (aka GASNet ofi-conduit) that provides high-quality support for Intel Omni-Path.
In particular, there should no longer be any reason to clobber Chapel's embedded version of GASNet-EX with an ancient/outdated GASNet-1 to get Omni-Path support, as suggested in the original question.
For more details see Chapel's detailed Omni-Path instructions.
I'm trying to automize WebSphere Deployment process for zero down-time using steps which you can find in this link..
According to documentation's first step , we should disable "Automatic Synchronization" for each node. To automize it, I'm using script which given in documentation but when I try to apply the command below :
set syncServ [$AdminConfig list ConfigSynchronizationService $na_id]
I'm facing with an error that : ADMG0007E: The configuration data type ConfigSynchronizationService is not valid
As I checked IBM documentations, I couldn't see any resource which referred to this problem.
Does anyone have any workaround or direct solution for it?
Thanks in advance for your suggestions.
PS: I should mention that document written for zOS system but I'm trying to apply that methodology to WebSphere AS on Linux.
I have installed openTSDB(.deb package) on ubuntu 15.04 by following the guidelines stated in documentation. when I give this command "service opentsdb start" it is not starting and it is mentioned in documentation that we have to change some configuration files.can anyone please tell me what are the changes that we have to do and in which file the changes have to be done?
Thanks in advance

Check your logs in /var/log/opentsdb/opentsdb.log. You should have HBase up&running correctly (means i.e. you are able to create table and store some values)
Remember you have to create tables in HBase running
env COMPRESSION=NONE HBASE_HOME=path/to/hbase-X.XX.X /usr/share/opentsdb/tools/create_table.sh
http://opentsdb.net/docs/build/html/installation.html#create-tables
In the vmc document from cloudfoundry, it says the "vmc services" command will return two tables, the first tables contains the available service types, and the second table returns the provisioned services instances. But I found with the latest version of vmc, the "vmc services" command only returns one table which contains "provisioned services". It's very in-convenient as I cannot see what kind of services the system can support.
Note: I found the very old version of vmc can list two tables.
Anyone have meet this issue?
For the latest version vmc, please use
vmc info --services
to get all the services available. Use
vmc help COMMAND
to get the usage of each command.
I believe the CF team is working on refining the document of all these stuff. They should soon make it better.
