Snapcreator configuration for SAP Sybase ASE

JOSEF_158
‎2013-11-22 06:06 AM

Hello.

I am trying to configure snapcreator to backup our Sybase database. I am using snapcreator 4.0p1 on Linux RHEL 6.4. The relevant part of my config file looks like this:

------------------------------------------------------

SYBASE_SERVER=SBT

SYBASE_USER=sybsbt

SYBASE_DATABASES=SBT:sapsa/93616c7425625f5f44b68281853be0e3219c33df62a8bc16c5adc374c7ed88e4

SYBASE_ISQL_CMD=/sybase/SBT/OCS-15_0/bin/isql

SYBASE=/sybase/SBT

SYBASE_LOGDIR=/sybase/SBT/saplog_1

------------------------------------------------------

   

However, when I start the command for backup, I receive following error during DB quiescence:

------------------------------------------------------

[2013-11-22 15:36:15,348] INFO: [dbhost:9090 (4.0.0.1)] SYBASE:QUIESCE: Quiescing database SBT

------------------------------------------------------

Another problem (that did not occure yet but i expect it to come) is that I have the DB installed with a virtual hostname (DB is using hostname that is not the same as OS host). Therefore the calling for isql must contain -X parameter otherwise an error will be displayed:

------------------------------------------------------

[root@host01 sybase]# /bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -Usapsa -Ppassword -SSBT -w 1024 -i /tmp/jYMsmsFNjz.sc"

Msg 1640, Level 16, State 2:

Server 'SBT':

Adaptive Server requires encryption of the login password on the network.

Msg 4002, Level 14, State 1:

Server 'SBT':

Login failed.

CT-LIBRARY error:

        ct_connect(): protocol specific layer: external error: The attempt to connect to the server failed.

------------------------------------------------------

 

How can I configure this -X parameter to be a part of -sql calling ?

 

Any assistance with these 2 problems would be appreciated.

Thank you.

Josef

Hello Siva and Karthikeyan for your help. I summarize here the information if anyone else would need to solve the problem. There were 3 more or less independent problems.

1) Connection to encrypted Sybase DB or DB running with different hostname. Add -X parameter to config file:

SYBASE_ISQL_CMD=/sybase/SBT/OCS-15_0/bin/isql -X

2) Problem with command not found:

[2013-11-22 15:36:15,349] ERROR: [dbhost:9090 (4.0.0.1)] [syb-00012] SYBASE:RUN_CMD: Command [/bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -Usapsa -Pxxxxx -SSBT -w 1024 -i /tmp/1qZre74f5v.sc"] failed with return code 256 and message -SSBT: Command not found.

Password of sapsa user must not end with exclamation mark .

3) Problem with quiescence of DB:

[Mon Dec  9 12:20:04 2013] ERROR: [dbhost:9090 (4.0.0.1)] [syb-00002] SYBASE:QUIESCE: Could not get Database master status, ensure database is running!

[Mon Dec  9 12:20:04 2013] ERROR: Task: quiesce with config:sybase@sbt failed

Must be solved with following steps:

a)

[sybsbt@host01~]$ isql -X -Usapsso -Ppasswd -SSBT -w 1024

1> use master

2> go

1> sp_configure "allow updates",1

2> go

(1 row affected)

Configuration option changed. ASE need not be rebooted since the option is dynamic.

Changing the value of 'allow updates to system tables' does not increase the amount of memory Adaptive Server uses.

(return status = 0)

1>

b) restart DB

c)

[sybsbt@host01~]$ isql -X -Usapsa -Ppasswd -SSBT -w 1024

1> use master

2> go

1> update master.dbo.sysdatabases set status = 0 where name = "master"

2> go

(1 row affected)

1> exit

Thanks again.

Br,

Josef

Hi Josef,

Maybe using "-S SBT" instead of "-SSBT" will already do the job!?

Also I would use "-P xxxxx" instead of "-Pxxxxx".

So, try to add a space after the options!

maybe this will help...

Thanks,

Horst

Hello Josef,

The error you have given is discussed here.

http://scn.sap.com/thread/3268654

In the above thread, they are suggesting to unlock the sa account as below.

$> isql -Usapsso -S<SID>

                       1> sp_locklogin 'sa', 'unlock'

                       2> go

Please let me know if that helps.

Also about the -X option

http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc30191.1550/html/utility/BABEFHFB.htm

This allows below.

-X

initiates the login connection to the server with client-side password encryption. -X enables both extended password encrypted connections and password encrypted connections without plain text password reconnection. isql (the client) specifies to the server that password encryption is desired. The server sends back an encryption key, which isql uses to encrypt your password, and the server uses the key to authenticate your password when it arrives.

If isql crashes, the system creates a core file that contains your password. If you did not use the encryption option, the password appears in plain text in the file. If you used the encryption option, your password is not readable.

Are you using encryption?  If not, you may not need the -X

Thanks,
Siva Ramanathan

Hello.

Thank you for your answer. The thread you refer to is discussing a general problem in connecting to Sybase DB but my problem is different. Anyway, to make really sure, I unlocked the account but the result is the same.

Anyway, I will try to re-formulate my problem once again to prevent any misunderstanding. I use snapcreator configuration file for my Sybase DB as described in my original post. When I try to run the backup command, I get following:

------------------------------------------------------

[root@host01 sybase]#

------------------------------------------------------

I belive my problem lies in the way how the snapcreator constructs the command to quiesnce DB. This part: Command [/bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -Usapsa -Pxxxxx -SSBT -w 1024 -i /tmp/_8kBhPV8Af.sc"] failed with return code 256 and message -SSBT: Command not found.    What is written in output debug file is naturally not exactly what is executed in background (my password is not xxxxx) and I would say that my password for sapsa is supplied by snapcreator in "" which creates problem for bash to interpret the command.

My second problem with -X parameter could be seen when I investogated the issue. I tried to run the command manually and this is the result:

------------------------------------------------------

[root@host01 sybase]# /bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -Usapsa -Ppasswd -SSBT -w 1024"

Msg 1640, Level 16, State 2:

Server 'SBT':

Adaptive Server requires encryption of the login password on the network.

Msg 4002, Level 14, State 1:

Server 'SBT':

Login failed.

CT-LIBRARY error:

        ct_connect(): protocol specific layer: external error: The attempt to connect to the server failed.

[root@tsbp01sap20 sybase]#

------------------------------------------------------

As written in previous error message, Adaptive Server requires encryption of the login password on the network. So if I specify -X parameter, I can log in sucesfully:

------------------------------------------------------

[root@host01 sybase]# /bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -Usapsa -Ppasswd -SSBT -w 1024 -X"

1>

------------------------------------------------------

As I wrote in my first post, i belive the reason is that I used virtual hostname for Sybase installation and therefore, although it is on the single host, it uses the "network communication" and -X parameter is needed.

Hope I managed to explain both issues a little better.

Thank you.

Josef

Hello ,

It executes following sql queries one by one and check at least one of the query satisfy, during quiesce operation.

#status3 - quiesce database - (AND)         True(Tq) & False(Fq)

" SELECT CASE WHEN (status3 & 128) = 0 THEN 'Fq' ELSE 'Tq' END AS [(qui)]

from master.dbo.sysdatabases where name=\"".$db."\"",

#status - mixed log and data - True(Tm) & False(Fm)

#status - no options set

" SELECT CASE WHEN status = 0 THEN 'Tm' ELSE 'Fm' END AS [(mix)]

from master.dbo.sysdatabases where name=\"".$db."\"",

#status - select_into/bulkcopy -(AND)       True(Ts) & False(Fs)

" SELECT CASE WHEN (status & 4) = 0 THEN 'Fs' ELSE 'Ts' END AS [(sel)]

from master.dbo.sysdatabases where name=\"".$db."\"",

#status - trunc_log_on_chkpt - (AND)        True(Tt) & False(Ft)

" SELECT CASE WHEN (status & 😎 = 0 THEN 'Ft' ELSE 'Tt' END AS [(trn)]

from master.dbo.sysdatabases where name=\"".$db."\"",

#status - ddl in tran - (AND) True(Td) & False(Fd)

" SELECT CASE WHEN (status & 512) = 0 THEN 'Fd' ELSE 'Td' END AS [(ddl)]

from master.dbo.sysdatabases where name=\"".$db."\"",

#status2 - abort_tran_on_log_full - (AND)   True(Ta) & False(Fa)

" SELECT CASE WHEN (status2 &  1) = 0 THEN 'Fa' ELSE 'Ta' END AS [(abt)]

from master.dbo.sysdatabases where name=\"".$db."\"",

#status - allow_nulls_by_default - (AND)    True(Tn) & False(Fn)

" SELECT CASE WHEN (status & 8192) = 0 THEN 'Fn' ELSE 'Tn' END AS [(aln)]

from master.dbo.sysdatabases where name=\"".$db."\""

Can you copy the one of the sql quey into /tmp/testfile and try to execute the below sql query from scagent running user, I hope you run the scagent as root user

/bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -Usapsa -Pxxxxx -SSBT -w 1024 –I /tmp/testfile

It look like ‘sybsbt’ user don’t  have access to "/sybase/SBT/OCS-15_0/bin/isql”.  I think some environment variable is missing.

Hello.

I created the /tmp/testfile with first SQL query:

------------------------------------------------------

SELECT CASE WHEN (status3 & 128) = 0 THEN 'Fq' ELSE 'Tq' END AS [(qui)]

from master.dbo.sysdatabases

go

------------------------------------------------------

When I try to execute it with the given command, it fails but only because this -X parameter is missing. Kindly see the output:

------------------------------------------------------

[root@host01 sybase]# /bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -Usapsa -Ppasswd -SSBT -w 1024 -i /tmp/testfile"

Msg 1640, Level 16, State 2:

Server 'SBT':

Adaptive Server requires encryption of the login password on the network.

Msg 4002, Level 14, State 1:

Server 'SBT':

Login failed.

CT-LIBRARY error:

        ct_connect(): protocol specific layer: external error: The attempt to connect to the server failed.

[root@host01 sybase]#

------------------------------------------------------

However, when I add this -X parameter, query is executed properly:

------------------------------------------------------

[root@host01 sybase]# /bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -Usapsa -Ppasswd -SSBT -w 1024 -i /tmp/testfile -X"

(9 rows affected)

[root@host01 sybase]#

------------------------------------------------------

For this reasons I belive that snapcreator is just not generating the command syntax properly (as mentioned before I would guess for a " character at password) and also this is the reason why I think that it is necessery to use -X parameter for a distributed SAP installation where virtual hostnames are used for SAP application server and also for Sybase database.

Thank you very much for your assistance.

Hello Josef,

Here is another thought.

Could you please try this and let us know the results?

SYBASE_ISQL_CMD=/sybase/SBT/OCS-15_0/bin/isql

to

SYBASE_ISQL_CMD=/sybase/SBT/OCS-15_0/bin/isql -X

Thanks,

Hello Siva.

Thanks much for your replay. Now the -X parameter problem is solved. System adds this parameter into the command. Howerver, there is still the problem with the command parsing:

------------------------------------------------------

[Tue Nov 26 08:19:51 2013] ERROR: [dbhost:9090 (4.0.0.1)] [syb-00012] SYBASE:RUN_CMD: Command [/bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -X -Usapsa -Pxxxxx -SSBT -w 1024 -i /tmp/eZpaHcl27p.sc"] failed with return code 256 and message -SSBT: Command not found.

------------------------------------------------------

Thank you for your help.

Josef,

You are correct in the assumption of debug logs showing xxxxx as the password.
Since we don't want the log files to hold sensitive information, we replace the password with xxxxx

Meanwhile, let me talk to who is the developer of this Sybase plugin and see how best to address this issue here.

Thanks much for bringing this to our attention.

Regards,
Siva Ramanathan

Hello Josef,

I am sorry, I did not find any solution yet.

Note: In the US, this is a 4 days holiday weekend, and my response will be delayed.

Here are the questions, I have.

1) Please login as sybsbt and provide me with the output of below commands.

set

which isql

echo $SYBASE

ls -al /sybase/SBT

cat /sybase/SBT/interfaces

I think, isql does not know about SBT. (because of missing interfaces or wrong interfaces file)

Thanks,
Siva Ramanathan

Thank you Josef.

1) Please provide me with cat /sybase/SBT/SYBASE.csh

2) netstat -na | grep 4110

3) Does your password end in ! character? (like mypassword!)

     If so, please try changing the password to something simple and try again.

     If the password ends in ! and csh might interpret as history character (unless you escape using \!) - this might make the script to throw -SSBT command not found error.

Please let me know.

Thanks.

Hello Josef,

Are you able to ping dbhost?

from [sybsbt@host01 ~]$ping dbhost

If you are not able to ping you may add an entry to /etc/hosts for dbhost

Hi.

Yes of course, I can ping the dbhost. But even if I could not, I would probably not see an error message saying "-SSBT: Command not found." 🙂

[Tue Nov 26 08:19:51 2013] ERROR: [dbhost:9090 (4.0.0.1)] [syb-00012] SYBASE:RUN_CMD: Command [/bin/su - sybsbt -c "/sybase/SBT/OCS-15_0/bin/isql -X -Usapsa -Pxxxxx -SSBT -w 1024 -i /tmp/eZpaHcl27p.sc"] failed with return code 256 and message -SSBT: Command not found.

The problem must be in command parsing. Either snapcreator does not correctly compose the command or something in the environment variable causes parsing to fail. Anyway, my installation is clean SAP NW on Sybase ASE with no additional setup. It is just installed as High-Available installation, thats all. Maybe it could be possible for NetApp to reproduce the error in some sandbox environment ?

Br,

Josef

Just to double check again,

your  snapcreator agent hostname in the prompt says as "host01" (why host01 and why not dbhost?)

Are you able to ping it from the host01 itself? not from outside (ex: from snap creator server)

Because, I am seeing similar messages in the SAP communities when the hostname is not resolved properly.

The other thing you can test for me is replace dbhost with IP address in the file below and try a backup again.

[sybsbt@host01 ~]$ cat /sybase/SBT/interfaces

SBT

        master tcp ether dbhost 41101

        query tcp ether dbhost 41101

SBT_BS

        master tcp ether dbhost 41102

        query tcp ether dbhost 41102

SBT_JSAGENT

        master tcp ether dbhost 41103

        query tcp ether dbhost 41103

Sure, I will try to reproduce this in the lab as time permits this week.

Thanks,

Siva Ramanathan

Hello Siva and Karthikeyan for your help. I summarize here the information if anyone else would need to solve the problem. There were 3 more or less independent problems.

1) Connection to encrypted Sybase DB or DB running with different hostname. Add -X parameter to config file:

SYBASE_ISQL_CMD=/sybase/SBT/OCS-15_0/bin/isql -X

2) Problem with command not found:

Password of sapsa user must not end with exclamation mark .

3) Problem with quiescence of DB:

Configuration option changed. ASE need not be rebooted since the option is dynamic.

Changing the value of 'allow updates to system tables' does not increase the amount of memory Adaptive Server uses.

(return status = 0)

1>

b) restart DB

c)

[sybsbt@host01~]$ isql -X -Usapsa -Ppasswd -SSBT -w 1024

I'd be extremely careful to update status within the master database! That's definitely asking for problems down the road.

I ran into the same defect with Snapcreator's Sybase ASE plugin myself some time ago, with some new SAP systems running on Sybase ASE 15.7.SP101.

As documented in this thread, the plugin searches for databases status modulo various, most important for the databases model and master is mod 0. In older releases this was correct, these database had status 0.

But things changed with ASE version 15.7 SP100 and higher. I had to open  SAP call to clarify, here's the answer

[quote=SAP]

Status 1 in sysdatabases is correct for model and master.

ASE 15.7 SP100 has various new features, amongst on handling text columns and shrink database, that require certain ASE internals to be in place. The status value of 1 in sysdatabases from ASE 15.7 SP100 is to show that the database was created using ASE 15.7 SP100 or higher or was upgraded to successfully to that version and thus that ASE can be certain these internals are correct. This new value was introduced with CR 733495, the documentation wasn't yet updated, this will be done with CR 693828 "Doc CR: ASE sysdatabases status columns need to include newer values in manual pages.".
I've created KBA 1938310 (will be released shortly) to document this, please contact your backup tool vendor to check their routines. Thank you.

[/quote]

SAP note 1938310 exists nowadays.

Personally I made a workaround of changing the status query for status=0  status =1 and it works. Wanted to open a NetApp support case last year but got sidetracked with other things, guess I'll do it today since I found this thread by chance to get an official fix (or est. date for a fix)

Again, do not update status bits of databases in 15.7.SP100, that could end ugly when you want to upgrade in few months and find weird errors from the upgrade scripts...
